Economic mobility is key to achieving human progress and aspiration, as it determines the living standards of future generations. Taking advantage of the expenditure data in two decades of the Indonesian Family Life Survey (IFLS), we measure intergenerational expenditure mobility and use a novel Unconditional. We found that there has been a clear trend of welfare improvement across generations. Findings of high absolute and relative intergenerational mobility among the poorest and most vulnerable groups in Indonesia reflect the success of children in climbing above their parents on the economic ladder. The absolute intergenerational expenditure mobility is high and insensitive to age group among the poorest 40%. Moreover, the relative intergenerational mobility is also very high, with 9.29% of parents in the lowest quintile able to have their children climb to the highest quintile. OLS and UQR estimations show that the Intergenerational Elasticity of Expenditure (IGE) ranges from 0.162 to 0.192. The determinants of mobility are children’s years of schooling, age, gender of the household head, and asset ownerships of children. Timing of household split-off among parents and children have varying degrees of importance for absolute and relative mobility, with different impacts along the distribution. Hence, our findings suggest that an understanding of intergenerational expenditure mobility is critical in ensuring better living standards while maintaining less inequality.

1. Introduction The universal desire of parents to see their children achieve higher living standards and the inherent desire of individuals themselves to climb higher up the economic ladder has determined the rise and fall of civilizations. Thus, intergenerational economic mobility (IGM) has long been, and continues to be, a key element in human progress and aspiration. Indeed, the promise of a better life is one which governments around the world pledge to their people. Yet, recent evidence finds that, despite massive progress towards equal access to opportunities, IGM trends have stalled since the 1960s, indicating that societies have been less successful in generating greater and shared prosperity (Narayan et al., 2018). A growing body of literature on IGM aims to understand the dynamics and determinants of economic mobility, as they are critical in reducing poverty, raising welfare and growth, and promoting equality. A low absolute IGM signals a low improvement in living standards; while a low relative IGM implies that privilege and poverty are highly persistent across generations (Narayan et al., 2018, p.57). One commonly used measure of IGM is the relative measure of intergenerational elasticity (IGE), which measures the differences in outcomes between children of low-income and high-income parents. However, research on intergenerational mobility that focuses on measuring and analyzing intergenerational elasticity has largely been conducted in developed countries (Cervini-Plá, 2015; Chetty et al., 2017; Chetty, Hendren, Kline, & Saez, 2014; Chetty, Hendren, Kline, Saez, & Turner, 2014; Corak, 2013; Corak, Lindquist, & Mazumder, 2014; Osterberg, 2000; Solon, 1999, 2002), and less in developing countries in China, Africa and Latin America (Gong, Leigh, & Meng, 2012; Lambert, Ravallion, & van de Walle, 2014; Narayan et al., 2018; Neidhöfer, 2019). This poses a challenge as most studies estimate IGE using the incomes of both parents and offspring; in developing economies, income data is relatively weak collected by statistical offices and also a less accurate measure of welfare (Bavier, 2008; Fields, 1994; Meyer & Sullivan, 2003). Unlike in developed countries, in developing countries consumption expenditure is viewed as the preferred indicator in measuring welfare or living standards because consumption can capture long run welfare levels than income (World Bank., 2001). Consumption is less vulnerable to under-reporting bias as income may fluctuate overtime due to some shocks or lifecycle income, while consumption may smooth across seasons or years by saving or dissaving or by other consumption smoothing mechanism. Consumption is more direct measure of material well-being and a better basis for determining economic status than is income (Bavier, 2008; Meyer & Sullivan, 2003). Many studies have explored in the extent to which economic well-being is transmitted across generations. Most of studies have focused on the intergenerational income mobility or elasticity ( for example Chetty, Hendren, Kline, & Saez, 2014; Corak, 2013; Gregg, Macmillan, & Vittori, 2019; Solon, 1999, 2002), where a relatively little attention on the intergenerational mobility in consumption expenditure (Aughinbaugh, 2000; Bruze, 2018; Charles, Danziger, Li, & Schoeni, 2014; Lambert et al., 2014; Waldkirch, Ng, & Cox, 2004). 2
Consumption is more directly related to consumer’s utility than other indicators. Moreover, the intergenerational expenditure correlation might also reflect a particular preferences in the family utility function that might not associate strongly in income or wealth correlation(Charles et al., 2014). Therefore, the exploration on the intergenerational mobility in consumption expenditure may reveal new insights about the transmission of well-being across generations. Additionally, an understanding of the intergenerational persistence of consumption allows for the analysis of long-run saving behaviors, consumption smoothing, and wealth inequality (Bruze, 2018). This paucity of literature is concerning, especially because intergenerational mobility is heavily linked with the success of developing economies. Therefore, taking advantage of the availability of long-term panel data (the Indonesian Family Life Survey, or IFLS, that spans 21 years), we examine the inequalities of opportunities that persist in a developing economy, the channels through which they are perpetuated, and the characteristics that allow low mobility to be broken. As a diverse country undergoing major economic, social, environmental, and political upheavals, Indonesia's history of intergenerational mobility can provide rich insight into how economic mobility varies within developing countries. Existing literature on Indonesia only explores intragenerational economic mobility (Dartanto, Moeis, & Otsubo, 2019; Dartanto & Otsubo, 2016) and the effects of child poverty on future labor outcomes (Rizky, Suryadarma, & Suryahadi, 2019). The study of intergenerational mobility across generation in Indonesia is fairly new. We then aim to close this research gap by using the IFLS data set to explore the absolute and relative intergenerational expenditure mobility. This study also introduces the novel method of unconditional quantile regression (UQR), which has only recently been used in the canon of IGM literature. The results guide policy makers to better design policies so that they can foster greater equality of opportunities, reduce low mobility, and thereby facilitate the fulfilment of people's aspirations. This paper proceeds with a literature review discussing various measures of intergenerational mobility, the findings of past research around the world, and debates regarding appropriate methodologies. Then, the third section presents an overview of the IFLS dataset is given, along with details on how classifications, thresholds, and percentiles are constructed. The fourth section follows with an exploration of changes and trends in living standards in Indonesia. The fifth section describes the research methodologies employed to delve further into the data, and the results are analyzed in the sixth section. The paper concludes by summarizing our main findings and considering their policy implications. 2. Literature Review on Intergenerational Mobility 2.1 Concept of Absolute and Relative Intergenerational Mobility Economic mobility itself is the ability of individuals, families, and groups to improve their economic status. The focus is often on incomes as a measure of living standards, and strands of literature in economic mobility study 3
intragenerational (the ability of individuals to climb the economic ladder within their own lifetimes) and intergenerational (the ability of children to climb above their parents in the economic ladder) mobility. The general convention in estimating intergenerational mobility is to distinguish between relative and absolute measures; measures of mobility can also differ by the outcome variable of interest (e.g. educational mobility, income mobility, consumption mobility, etc.) and by how outcome variables are distributed (e.g. continuously or discretely). When variables are discretely distributed, individuals are often grouped into quartiles or quintiles and the probabilities of transition between quantiles is a measure of relative mobility that can be organized into a transition matrix (Narayan et al., 2018). Relative mobility measures the extent to which children’s outcomes depend on their parents’ outcomes. The greater the dependence, or the greater the intergenerational persistence (IGP) in outcomes, the less intergenerational mobility there is. Conversely, greater independence implies greater intergenerational mobility as it indicates that the fate of children is less constrained by the fate of their parents. Widely used measures of relative mobility include intergenerational elasticity, which is obtained by regressing log child outcomes with log parent outcomes, and the rank-rank slope, which measures the relationship between children’s positions and their parents’ positions on the income distribution (Chetty, Hendren, Kline, & Saez, 2014; Narayan et al., 2018). However, both measures possess the drawback that they are unable to differentiate between upward and downward mobility, are informative of non-linearities in mobility (e.g. whether mobility is greater or lower in certain parts of the distribution), and, as will be further discussed later, can also be sensitive to how outcomes are measured and distributions are varied (Corak et al., 2014; Gregg et al., 2019). Thus, Corak et al., (2014) utilizes a directional rank mobility measure which resolves, to an extent, the first two drawbacks, and Gregg et al., (2019) applies an unconditional quantile regression to resolve the latter drawback. Meanwhile, absolute mobility measures the extent to which children’s outcomes differ from their parents. There are three widely used measures of relative mobility. Absolute upward mobility measures the mean rank (or percentile in the national distribution) of children whose parents are located at a certain percentile in the national distribution. In the context of income mobility, Chetty, Hendren, Kline, & Saez, (2014) estimates the mean rank of children whose parents are at the 25th percentile in the national income distribution. Although this measure is analogous of the rank-rank slope at the national level, when analysis is conducted at smaller levels, the measure becomes an absolute measure as incomes in individual areas have little effect on the national distribution (Chetty, Hendren, Kline, & Saez, 2014). The second measure of absolute mobility estimates the probability of rising from the bottom quintile to the top quintile, and the third measure estimates the probability that a child will exceed a certain threshold (e.g. poverty line) given that their parent’s income is at a certain percentile (Chetty, Hendren, Kline, & Saez, 2014). 4
Absolute mobility is important as, ceteris paribus, it allows for Pareto improvements in welfare that do not come at the expense of other groups in society. It is required for the improvement of living standards because it measures the ability of societies to expand the economic pie so that different groups do not compete for the same slice of a stagnant or shrinking pie and social cohesion does not deteriorate (Chetty, Hendren, Kline, & Saez, 2014; Narayan et al., 2018). Meanwhile, rising relative intergenerational mobility does not necessarily indicate that the living standards of the poor are improving; it may indicate that the rich are doing less well than they did in the past. However, even such trends in mobility are important; an absence of relative mobility represents intergenerational persistence of inequalities of opportunity, wasted human potential, and misallocation of resources. Thus, both measures of intergenerational mobility are necessary for economic progress and for the sustainability of the social contract that addresses the aspirations of society (Narayan et al., 2018). Studies using both relative and absolute measures of mobility find a wealth of diversity in intergenerational performance and its determinants. Chetty, Hendren, Kline, & Saez, (2014) finds that IGM in income varies widely in the United States, with high mobility areas being characterized by less residential segregation, lower inequality, better primary schools, greater social capital, and greater family stability; significant childhood exposure effects to neighborhood characteristics are further found in (Chetty & Hendren, 2018). In the United Kingdom, childhood exposure effects are also significant, but in terms of early skills, education, and early labor market attachment, as these variables mitigate, albeit not fully, the strong intergenerational persistence in the country (Gregg et al., 2019). A comparison of IGM in income among several developed economies finds that Britain’s exceeds Spain’s, and Spain’s is similar to France’s but exceeds Italy’s and the United States (Cervini-Plá, 2015). When direction of mobility is considered, it is found that Canada possesses higher downward mobility than Sweden and the United States, while upward mobility is similar in the three countries (Corak et al., 2014). In all countries, the extent of IGM and its determinants are nonlinear across the distribution; for example, returns to education are higher at the top of the income distribution while youth unemployment most adversely impacts the mobility of those at the bottom of the distribution (Gregg et al., 2019)(Gregg et al., 2019). These nonlinearities may reflect the availability of egalitarian public facilities and redistributive welfare programs (Torche, 2015). The scope of IGM may be broadened by extending analyses beyond earnings and income to include other outcome variables such as educational mobility, occupational status mobility, class mobility, and gender-based mobility. Narayan et al. (2018) provides a highly comprehensive analysis of intergenerational educational mobility across the world, as extended datasets on education are widespread and comparable, allowing educational mobility to be uniquely studied at the global level. Moreover, Intergenerational persistence is stronger in developing economies, where the education of 5
grandparents influences the educational attainment of individuals to a greater extent than that found in richer economies (Narayan et al., 2018). 2.2 Intergenerational Expenditure (Consumption) Mobility It is, however, evident that a majority of these studies have been conducted in developed economies. Yet, Narayan et al. (2018) show that IGM trends in developing economies are different to those observed in more developed ones. We now turn to another novel approach to mobility is to analyze mobility in consumption or expenditure rather than income. If measurements of IGM aim to measure how living standards of children are affected by their parents’ living standards, then consumption or expenditure would be a better indicator of material welfare than income (Bruze, 2018; Deaton & Zaidi, 2002; Meyer & Sullivan, 2003). A small number of studies have used consumption as a proxy for IGM, and although studies on United States data reach conflicting results, Bruze (2018) finds that, in Denmark, intergenerational elasticity of consumption significantly exceeds both intergenerational elasticity of disposable income and intergenerational elasticity of earnings. Such findings indicate that calculating intergenerational persistence using intergenerational elasticity of earnings (the lowest among the three measures) can greatly underestimate the persistence of living standards and therefore overestimate economic mobility. The intergenerational mobility of consumption approach is also particularly relevant in the context of understanding IGM in developing countries, as income datasets may not be available or are poorly collected in many developing countries, hence making income a less accurate measure of welfare. Although lengthy expenditure datasets that are sufficient to describe intergenerational mobility are rare for developing economies, those that do exist can provide unique insight into the extent of economic mobility found in poor, primarily rural, and largely agricultural societies, many of which are struggling to raise their standards of living. Lambert et al., (2014) uses expenditure data on Senegal to understand the dynamics of intergenerational mobility and interpersonal inequality, and they discover that mobility is higher when greater economic activity of women and a shift away from farming sectors are observed. They also discover that inheritance of land and housing have little effect on children’s consumption and on inequality, whereas inheritance of non-land assets, parental education and occupation, and parental choices about children’s schooling play more significant roles in raising the child’s welfare as an adult. These positive intergenerational effects were found to be stronger from the mother’s side. While debates on the efficacy of absolute versus relative measures have long existed in estimating intergenerational mobility, there has recently arisen debates regarding the use of conditional versus unconditional measures (Gregg et al., 2019). The relative and absolute measures discussed above are the result of conditional regressions and are therefore subject to greater sensitivity towards the distribution of variables. The measures are conditional because they rely on the child’s conditional income distribution in order to 6
obtain a conclusion about economic mobility. Conditionality not ideal because the pre-regression rank order of children’s earnings is not the same as that for the post-regression residuals, causing unclear interpretation of coefficients (Firpo, Fortin, & Lemieux, 2009; Gregg et al., 2019). Also, conditionality creates difficulties in adding covariates, as conditional quantiles vary across specifications. For example, the distribution for someone at the 10th percentile of the wage distribution of university graduates may not be the same as the distribution for someone at the 10th percentile of the wage distribution of all workers. Therefore, unlike OLS estimates, conditional quantile regression (CQR) estimates do not allow us to retrieve the marginal impact of a specific variable (e.g. university education) on the unconditional quantile of the dependent variable. They only allow us to conclude what the distribution (e.g. the expected value or mean) of the child’s outcome variable will be (Firpo et al., 2009; Gregg et al., 2019). 3. Measuring Intergenerational Mobility: Methods and Dataset 3.1 Absolute Mobility: Measurement and Determinants We now turn to empirical estimates of absolute and relative mobility using consumption expenditure data. As previously noted, expenditure or consumption can be a more accurate representation of living standards, particularly in developing economies (Aughinbaugh, 2000; Bruze, 2018; Charles et al., 2014; Lambert et al., 2014). Following Chetty et al., (2017) but modifying for our use of expenditure instead of earnings to measure mobility, we define absolute mobility, !" , as the percentage of children in cohort c that & spend weekly more than their parents. Let $%" denote the expenditure ' (capita/month) of child i in cohort c, $%" denote the expenditure (capita/month) of their parent, and (" be the number of children in the cohort. We use the consumer price index to convert the nominal value of expenditure into the real term of expenditure per-capita. During two decades, the consumer price index had jumped from 100 in 1993 becoming 763 in 2014. Then, absolute mobility is defined as: 1 !" = & + 1{ $%" ≥ $%"' } (" % Children and parents are then divided into two cohorts, based on whether they are aged above or below 40 years old. The children of ages 20 to 40 years old in 2013 with parents of ages 20 to 40 years old in 1993 are grouped into one cohort, and children of ages 40 and above in 2014 with parents of ages 40 and above in 1993 are grouped into another cohort. The expenditures of children and parents within cohorts are compared in order to obtain absolute mobility. Although grouping different ages into one cohort and distinguishing cohorts using the age of 40 as a threshold may introduce biases such as the life-cycle bias, we find that such a division results in the most consistent estimates. Moreover, it is intuitive to divide the sample using such a threshold because we observe divergent trends in mobility between the two cohorts. 7
Logit models are also regressed in order to identify the marginal effects of parents’ conditions in 1993 and their children’s conditions in 2014 on intergenerational mobility. The first model includes only variables describing parents’ conditions in 1993, while the second model also includes variables describing children’s conditions in 2014. Two variants of each model is regressed: one showing the marginal effects for when the expenditure distribution is grouped into deciles, and another for when it is grouped into vigintiles. & ' ' $%" = / 0 + 230 4%3 + ⋯ + 260 4%6 + 7%0 4%6 & + ⋯ + 7%0 4%6 & + 8% & where, $%" is the discrete variable of the absolute mobility of children in which 1 represents that children has a higher or equal rank than their parents ' and 0 represents that children has a lower rank than their parents. 4%9& :4%9 ; denotes child (parent) i's j-th characteristic of interest (e.g. child i's level of education) whereas 290 & 790 denote the returns or impacts of those characteristics at each quintile s across the distribution (Gregg et al., 2019). 3.2 Measuring Relative Mobility and Unconditional Quantile Regression Relative mobility is then estimated as the intergenerational elasticity, rank-rank slope, and directional rank mobility (Chetty, Hendren, Kline, & Saez, 2014; Corak, 2013; Corak et al., 2014; Gregg et al., 2019). The intergenerational expenditure elasticity is obtained by regressing log child income (logYi) on log parent income (logXi), whereas the rank-rank slope is obtained by calculating the correlation between the child’s position (quantile rank, represented by Ri) on the expenditure distribution and the parent’s position (quantile rank, represented by Pi) on the distribution. The rank-rank slope can be obtained by regressing Ri on Pi. Mathematically, the regression coefficients may be represented as (Chetty et al., 2914): CB MN(HEIK% ) =>? = @AB = DEFF(HEI4% , HEIK% ) CA MN(HEI4% ) OPQR SHETU = @VW = DEFF(X% , O% ) When the elasticity and slope are higher, intergenerational expenditure mobility is lower, because the two measures represent the intergenerational persistence in expenditure. The elasticity and slope differ only to the extent that inequality or the standard deviation of expenditures is higher across generations, with rising inequalities leading to a greater intergenerational elasticity (Chetty et al., 2014). Finally, in addition to the conditional measures above, we also conduct unconditional quantile regressions in order to identify covariates which influence intergenerational expenditure mobility. Ranking the children into quintiles, we apply the re-centered influence function (RIF) technique as found in Firpo et al. (2009) and Gregg et al. (2019): & O=Y:$%" ; [0 ; = / 0 + \ "0 $%"' + 230 4%3 ' ' + ⋯ + 260 4%6 + 7%0 4%6 & + ⋯ + 7%0 4%6 & + 8% 8
using UQR at different quintiles [0 where s takes the values of 0.2, 0.4, 0.6 and 0.8. The estimate \] "0 is the association between parent and child expenditures, conditional on all other variables. 4%9& :4%9' ; denotes child (parent) i's j-th characteristic of interest (e.g. child i's level of education) whereas 290 & 790 denote the returns or impacts of those characteristics at each quintile s across the distribution (Gregg et al., 2019). As discussed above, the use of the UQR and RIF approach allows for straightforward interpretation of the marginal effects of each variable, but with modifications for discrete variables. In estimating our RIF, we divide variables into two groups: the condition of parents in 1993, and the condition of children in 2014. Both groups of variables include parents’ and children’s respective age, gender of the household head, years of schooling, location of the household, and value of asset ownership. Moreover, in order to add nuance to the condition of children in 2014, we also include as a variable the year in which children split from their parents’ households to create a new household of their own. The use of unconditional quantile regression (UQR) allows for consistent interpretation of additional covariates in the model and for between-group comparisons because quantile distributions no longer vary across specifications. Coefficients for continuous variables such as income may be interpreted in the same way as OLS estimates, although for discrete variables such as years of schooling, the UQR coefficient reflects the impact of an increase in the proportion of schooling in the quantile (Firpo et al., 2009; Gregg et al., 2019). Unconditional quantiles are constructed using a re-centered influence function (RIF) that allows mobility to be estimated more reliably at different parts of the distribution and for additional variables to be added consecutively to the regression (Firpo et al., 2009). CQR and UQR estimates can differ greatly from each other, and their divergence can also provide insight into mobility dynamics. 4. Indonesia Family Life Survey (IFLS) Dataset and Overview of Intergenerational Mobility 4.1 Overview of the Indonesia Family Life Survey (IFLS) Dataset We use mainly the 1993 and 2014 waves of the IFLS to measure intergenerational expenditure mobility in Indonesia throughout the last two decades. The IFLS is a longitudinal survey, in which the sample of households in subsequent waves are primarily determined by the household sample in the first wave. The first wave, or the IFLS1 was conducted in 1993 following the sample frame of the national socio-economic survey (SUSENAS). The IFLS1 used a sampling scheme that stratifies by provinces, then conducts random sampling within provinces. The sampled provinces were the thirteen major provinces of Indonesia where approximately 83% of the population resided.1 The IFLS dataset provides uniquely rich detail of households’ demographics, 1 The original sample represented around 83% of the population, but recent samples cannot guarantee a similar representation rate due to attrition, split-off households, and migration. 9
socioeconomic characteristics, consumption behaviours, health conditions, and access to community facilities and social safety nets (see Frankenberg and Karoly 1995 and Frankenberg and Thomas 2000). The IFLS1 interviewed 7,224 households, while the IFLS2 in 1997 interviewed 7,619 households. The sample increased as split-off households created when children began their own households were also surveyed in IFLS2; around 11.5% of IFLS2 households are split-off households. In the IFLS3 conducted in 2000, approximately 35% of the households surveyed were split- off households, including those who split in and after 1997. The IFLS4 interviewed 13,535 households; the IFLS5 interviewed 16,930 households of which 5,053 were original IFLS1 households, 7,862 were old split-off households from IFLS2, 3, and 4, and 4105 were new split-off households. However, despite the richness of the data, we focus only the original households of IFLS1 because it is those households which always appear in every wave of the survey throughout the last two decades. The attrition rate is usually the Achilles heel of longitudinal studies. Yet, unlike many longitudinal household surveys in many developing countries where follow-up surveys explicitly target only the subset of respondents remaining in their baseline location, the IFLS aims to minimize attrition by constantly tracking respondents who move to other locations. Thomas et al. (2001) show that the attrition between the baseline and second follow up is only 5%. At least one member of every 20-target households was re-contacted in each of the three follow-up surveys (Thomas et al., 2012; Dartanto et al., 2019). The critical feature behind successful tracking is to provide interviewers and trackers with detailed information on a wide range of the individual, household, and family attributes of respondents (Thomas et al., 2012). Having merged the IFLS1 and IFLS5, we calculated an attrition rate of only 16.33%. 2 As our focus is not only on intergenerational welfare mobility throughout the two decades of survey data but also on its determinants, we create a combined dataset of all household characteristics of parent households in IFLS1 and their children’s households in IFLS5 for econometric estimations. Among the characteristics we include are the education, gender, age, expenditure pattern, and asset ownership. 4.2 Overview of Absolute and Relative Intergenerational Mobility Figure 1 shows the density of expenditure per capita. In 1993, the expenditure was highly dense between IDR10,000-50,000 per capita per month. However, in recent years, the density in real terms has flattened out, being more dispersed, which may be signal lower equality across generations. Meanwhile, Figure 2 shows that absolute mobility declines as parent expenditure increases, with absolute mobility being highest for the poorest and most vulnerable groups at the bottom of the distribution. Moreover, for those 2This attrition rate is the household attrition rate, not individual attrition rate. It is possible that the individual attrition rate is much higher than that of households. 10
whose expenditures are in the bottom 40% of the distribution, absolute mobility is not sensitive to the age at which the child’s and parents’ expenditures are measured. This is desirable, because regardless of the stage of life of parents or children, the most vulnerable children are able to consume more than their parents, therefore implying greater chances for those children to achieve better living standards than their parents. Yet, as we move up the expenditure distribution, we find that absolute mobility becomes sensitive to the age at which it is measured, with intergenerational expenditure mobility being greater for those in the 20- to 40- year-old cohort than those in the 40-and-above cohort. The factors influencing this mobility gap among the non-poor are left to future work, as we are largely concerned with intergenerational mobility among the poor, for whom moving up the income ladder has the highest stakes. Still, we explore some of the dynamics behind the differences in the following section, where we examine in greater detail some of the determinants behind absolute and relative mobility, one of which being the age at which children split off from their parents’ households to begin their own household.

Figure 4 illustrates the long run transition of intergenerational consumption mobility between parent and children. Around 9.19% of children from the 1st quintile of parents can climb up the economic ladder into the 5th quintile income during two decades, while 33.65% of children of the 1st quintile remained at the same quintile. However, only 35% of children from the richest expenditure group (quintile 5) can maintained their consumption level as same as their parents. Most of them dropped to the lower expenditure group. Surprisingly, around 9% of children from the richest expenditure group became the poorest group. These figures verify that the individual in Indonesia is very mobile both upward and downward mobility. Figure 4.

5. Analysis of Results 5.1 Absolute Intergenerational Mobility Having observed the general trends in intergenerational mobility, we first turn to our logistic regression which attempts to identify the marginal effects of various variables on the probability of absolute upward mobility or, equivalently, of a child’s expenditures weakly exceeding their parents’ expenditures. Results for when the distribution is divided into deciles and into vigintiles are similar for almost all variables. When only the characteristics of parents are considered, we find that parents living in urban areas and an increase in parents’ years of schooling reduces the probability of absolute mobility. This is natural as the more educated parents are, the higher their expenditures are likely to be, thereby reducing the room that children have to increase expenditures beyond their parents’ levels. Similarly, the older parents are in 1993, the less chance for absolute upward mobility in children, which may be linked with the ability for parents to provide for themselves and or their children. Meanwhile, when characteristics of children are also considered, the effect of the age of parents in 1993 reverses and becomes insignificant. The value of parents’ asset ownership becomes a negative and significant determinant of chances for absolute upward mobility, and the age of the child themselves also negatively impacts chances for mobility. Chances of upward mobility are further negatively influenced by the year in which children split away from their parents’ households to create their own households. However, the child’s own years of schooling, residence in urban areas, and asset ownership increases the probability of greater expenditures. Together, these findings reflect intergenerational persistence because parents’ conditions diminishes chances for mobility, but with the persistence being weakened due to the child’s ability to influence their absolute outcomes through their own attributes. Yet, these results must be treated with caution, as the conditionality of the measure on the distributions within each quantile can result in inconsistent estimates and misleading interpretations. Additionally, the marginal effects provide no clarity on the non-linearities of the effects along the expenditure distribution, therefore limiting their insight and usefulness. Therefore, we now turn to our unconditional quantile regression results. We find that although value of parents’ asset ownership influences absolute mobility, it does not influence relative mobility. The negative effects of parents’ years of schooling on absolute mobility is contradicted by its positive effects on relative mobility. Still, the effects of the child’s age, years of schooling, value of asset ownership, and timing of household split-off remain similar for absolute and relative mobility. The differences between the results can provide policy guidance for which aspects of individuals and households to target in order to achieve both an increase in living standards and a reduction in inequality. 14

earnings and education in Indonesia and other economies, the different estimates for mobility that intergenerational expenditures provide may indicate that children’s living standards are less constrained by their parents’ than previously thought. Both the IGE and the rank-rank slope for intergenerational expenditures fall but remain significant when other covariates are considered, with varying effects at each quantile of children’s expenditures. Based on the IGE resulted from both OLS and UQR estimations, we show that the IGM in Indonesia ranges from 0.80 to 0.83 :1 − \] "0 ;, while from the rank-rank regressions, the IGM ranges from 0.75 to 0.84. These mean that individual in Indonesia is very mobile in which children from a very poor family can easily climb up to the upper class. Unconditional quantile regression results from the IGE and rank-rank slope approach also generally concur with each other in terms of the variables that are significant in determining a child’s expenditure in 2014, although coefficients of the two approaches differ due to the different nature of the variables involved. However, as previously discussed, some results from the UQRs contradict the estimates obtained through the previous logit regression, especially as we find that the logit marginal effects to do not hold true at certain areas of the expenditure distribution. All UQRs indicate the importance of parents’ expenditures in determining their child’s expenditures across the income distribution, and agree that intergenerational persistence or correlation in expenditures is lower in the first quintile. This is desirable in the effort to reduce inequality, as it implies that the living standards of the very poor are relatively more mobile than their counterparts. The greater mobility among the very poor may also be reflected in our finding that the proportion of parents with greater years of schooling significantly and positively affects children’s expenditures in all quintiles except the bottom quintile. Moreover, the proportion of children with greater years of schooling significantly and positively affects their expenditures in all quintiles including the bottom quintile, indicating that, at least for the poorest group, children are able to improve their living standards through their own efforts in spite of their parents’ conditions. 16

Those implications are corroborated by the insignificance of parents’ value of asset ownership on their child’s expenditures across all quintiles, and the significance of the child’s own value of assets on their expenditures. The location of parents’ households is only notable for the top quintile, where an increase in the proportion of parents living in urban areas diminishes children’s expenditures. Similarly, the gender of household heads, in both parents’ and children’s households, is only relevant in the top half of the expenditure distribution, with a greater proportion of female-headed households raising relative mobility in the quintiles. The timing of when children’s households split away from their parents’ households is also only significant in that area. Household split-offs recorded in the 2000 and 2007 IFLS reduces the chances of greater expenditures among children in the top half of the distribution, while a household split-off in 1997 increases the chances of greater expenditures. No such effects are found for children in the lower half of the distribution. While we leave the exploration of the mechanisms behind this pattern to future work, the different effects observed imply that intergenerational mobility is influenced to an extent by the age and conditions at which children began their own households. 6. Concluding Remarks The improvement of living standards throughout the past two decades in the Indonesian economy has allowed millions of households to break free of poverty. This rise in well-being and resulting growth in Indonesia’s middle class can be attributed, in part, to trends in intergenerational mobility. Although most studies on mobility focus on income or earnings mobility, our study takes advantage of the IFLS dataset and uses per capita expenditures to compare parents and children, as consumption is a better reflection of living standards than income in developing countries. Our use of the novel unconditional quantile regression method also offers insight into some of the determinants of intergenerational mobility at various areas of the expenditure distribution. Dynamics of intergenerational mobility in Indonesia throughout the past two decades have been diverse, but there has been a clear trend of welfare improvement. Findings of high absolute and relative intergenerational mobility among the poorest and most vulnerable groups in Indonesia reflect the success of children in climbing above their parents on the economic ladder. Our econometric estimations highlight the role of education; children are able to determine their own outcomes in life, with years of schooling being consistently significant across the entire distribution. We find that other variables of age, gender, location, asset ownership, and timing of household split-off are also important in determining the living standards of children located in several areas in the distribution, with varying effects on absolute and relative mobility. Our study is the first to examine intergenerational expenditure mobility in Indonesia and to apply the unconditional quantile regression to assess 19
determinants of it in a developing economy. The diversity of our findings reveal that these approaches can provide more thorough insights to how governments should design policies that can raise living standards as well as reduce inequalities. Although we leave the detailed effects of some variables to future work, it is evident from the results presented here that both intergenerational expenditure mobility and its determinants are critical in determining the necessary and sufficient conditions for economies and governments to deliver not merely the wealth of nations but also the wealth of future generations. 7.
