Three Essays on Development Economics in China


Book Description

This dissertation is a collection of three independent essays in empirical development economics using data from China. In the first two chapters, I examine the determinants of choices within the household. In the first chapter, I estimate the causal effects of total income, relative female and relative male income on sex imbalance. The second chapter studies the effects of relaxations in the One Child Policy on sex ratios and family size and then exploits the exogenous variation in family size caused by the relaxations to estimate the causal effect of family size on school enrollment. The third chapter is a descriptive study of income inequality for top income earners in China during 1986-2002 and the potential redistributive effectiveness of progressive income taxation.




Essays in Empirical Development Economics


Book Description

This dissertation is a set of three independent essays on empirical development economics, with a focus on China. The first chapter examines the effect of maternal education on infant health by exploiting exogenous variation in women's exposure to the wholesale closure of rural high schools immediately after the Cultural Revolution, from 1977 to 1984. The second chapter explores the longterm effect of prenatal exposure to the 1978-84 land reform on academic performance, as captured by college entrance exam scores. The third chapter examines the effect of land reform on the sex ratio imbalance by comparing the sex of the second child between families with a first girl and those with a first boy before and after the reform.










Essays on Development Economics in China


Book Description

This dissertation consists of three applied economic studies on China. In winter 2006, I conducted a survey and field experiment to elicit the risk preferences of 320 Chinese farmers, who faced the decision of whether to adopt genetically modified Bt cotton a decade ago. The first two chapters use this dataset to examine the relationship between elicited individual risk preferences and farming decisions. The last chapter provides a meta-analysis of existing literature on the returns to education in China.




Three Essays on E-commerce Development and Inequality in China


Book Description

This dissertations consists three essays on development issues in contemporary China. Two essays focus on the role of e-commerce in China's economic development and the third essay studies the latest trend of Chinese inequality. China has been the world's largest e-commerce market since 2013. E-commerce development in China has been fast but uneven with the rural and inland markets relatively left behind compared with city and coastal markets. Since 2014, the Chinese government has been supporting major e-commerce development in rural and remote areas. Chapter One studies the effect of the national-wide rural e-commerce program on rural residents' labor market outcomes. One likely consequence of the expansion of e-commerce is saving in time cost of shopping for people in remote villages. This paper analyzes the impact of this time saving on labor supply of men and women in rural China. I first uncover the heterogeneity of response in e-commerce use to the government program with a machine learning approach. Then to investigate the causal effect of e-commerce expansion, I exploit an interaction IV strategy making use of the roll-out time of the government program and heterogeneous response of online shopping to the program across distance and age structure, as supported by findings from the machine learning approach. My estimates suggest that e-commerce expansion increases weekly labor supply by 7 hours and the probability of working in the wage sector by 14 percentage points by relaxing the time budget constraint. The result is significant for both men and women, but in a gender differentiated manner. It shifts labor away from self-employed agriculture to the wage sector for men, and from working inside the home to outside the home for women. Chapter Two studies how local e-commerce development affect household consumption growth and its structure. By matching a nationally representative China Family Panel Studies survey with county-level e-commerce information obtained from Alibaba, this chapter examines how e-commerce development has shaped household consumption growth in China. The paper presents three major findings. First, e-commerce development is associated with higher consumption growth. Second, the relationship is stronger for the rural sample, inland regions, and poor households, suggesting that e-commerce development helps reduce spatial inequality in consumption. Third, the consumption of in-style goods and high-income elasticity goods has grown faster than the consumption of local services. Chapter Three investigates the long-term evolution and latest trend of Chinese inequality. The chapter argues that after a quarter century of sharp and sustained increase, Chinese inequality is now plateauing and, according to some measures, even declining. A number of papers have been harbingers of this conclusion, but this paper consolidates the literature indicating a turnaround, and provides empirical foundations for it. The argument is made using a range of data sources and a range of measures and perspectives on inequality. The evolution of inequality is further examined through decomposition by income source and population subgroup. Some preliminary explanations are provided for these trends in terms of shifts in policy and the structural transformation of the Chinese economy. We relate the turnaround to two classic phenomena in the development economics literature-the Lewis turning point and the Kuznets turning point. The plateauing is not yet a full blown decline, and there are short term variations. But the narrative on Chinese inequality now needs to accommodate the possibility of a turnaround in inequality, and to focus on the reasons for this turnaround.




An Essay on Economic Reforms and Social Change in China


Book Description

Abstract: The author applies a systems-oriented "holistic" approach to China's radical economic reforms during the past quarter of a century. He characterizes China's economic reforms in terms of a multidimensional classification of economic systems. When looking at the economic consequences of China's change of economic system, he deals with both the impressive growth performance and its economic costs. The author also studies the consequences of the economic reforms for the previous social arrangements in the country, which were tied to individual work units-agriculture communes, collective firms, and state-owned enterprises. He continues with the social development during the reform period, reflecting a complex mix of social advances, mainly in terms of poverty reduction, and regresses for large population groups in terms of income security and human services, such as education and, in particular, health care. Next, the author discusses China's future policy options in the social field, whereby he draws heavily on relevant experiences in industrial countries over the years. The future options are classified into three broad categories: policies influencing the level and distribution of factor income, income transfers including social insurance, and the provision of human services.







Essays on Development Economics


Book Description

Randomized controlled trials (RCTs) have been widely adopted in the subject of Development Economics to study the causal impact of developmental interventions. In this dissertation, I empirically study the impacts of two developmental interventions on the skill formation during early childhood -- a crucial period for the human capital development -- using RCTs and theoretically identify the causal impact of developmental interventions under a particular but rather common circumstance in RCTs. The first chapter evaluates the medium-term impact of a six-month early childhood home-visiting program on child outcomes in rural China. Two and a half years after completion of the program, we find persistent intervention effects on child working memory -- a key skill of executive functioning which plays a central role in children's development of cognitive and socio-emotional skills. We also find that the program had persistent effects on both parental time investments and preschool enrollment, with children in the treatment group enrolling earlier and in better quality preschools. Our finding of improved parental preschool selection in treatment villages points to an important intervention-induced persistent shift in parental investment behavior which might lead to long-term benefits over the life-cycle. The second chapter examines the role of social interaction in child development using a random experiment of ECD intervention in rural China. The intervention promotes social interactions by providing both infants and caregivers of infants free access to a playground in rural villages. After one year, the intervention improved the language skills of infants, by 0.15 standard deviation (SD) and the parenting awareness of their caregivers, by 0.21 SD. Evidence suggests infants and their parents benefited from the intervention through social interactions: children benefited from the intervention through their own interactions with other similar-age children as well as their caregivers' interactions with caregivers of other similar-age children; caregivers improved parenting awareness by learning from other experienced caregivers. in the third chapter, we study the causal identifications in cluster randomized controlled trials when there are spillovers across individuals within clusters through social interactions and/or general equilibrium of clusters. Under these circumstances, we show the traditional local average treatment effect (LATE) can no longer identify the average treatment effect of the subpopulation that is treated. Instead, we propose an analogous causal estimator of LATE in clustered randomized experiments with spillovers across individuals within clusters. Under a mild difference-in-differences type assumption, we point-identify the local causal effect for the treated in clustered randomized experiments with spillovers and one-sided noncompliance. Furthermore, we can identify the indirect effect of interventions for the subpopulation that is not treated, which can be used to test whether the spillover effect exists. We illustrate our method in our empirical analysis of a microcredit program in rural Morocco.
