We develop and estimate a life-cycle model in which individuals make decisions about consumption, human capital investment, and labor supply and use it to analyze changes in Social Security rules. The most important aspect of our paper is human capital towards the end of the life cycle which responds to changes in the rules. Retirement arises endogenously as part of the labor supply decision. The model allows for both an endogenous wage process through human capital investment (which is typically assumed exogenous in the retirement literature), an endogenous retirement decision (which is typically assumed exogenous in the human capital literature), and accounts for the Social Security system. We estimate the model using indirect inference to match the life-cycle profiles of employment and measured wages from the SIPP data. The model replicates the main features of the data--in particular the large increase in measured wages and small increase in labor supply at the beginning of the life cycle as well as the small decrease in measured wages but large decrease in labor supply at the end of the life cycle. We use the model to estimate the effects of various changes to tax and Social Security policies and show that allowing for human capital accumulation is critical.

This dissertation consists of three independent essays on earnings dynamics, educational production function, and retirement. Each chapter explains labor supply and human capital formation from a life-cycle perspective. In the first chapter, I investigate how two different kinds of uncertainty jointly affect young workers' decisions. This paper introduces the possibility of multidimensional learning about worker ability and job match quality into a model of work decisions. This mechanism has a unique prediction, negative sorting into job mobility that fades away over time, which is verified in the NLSY79 data if the AFQT score carries over some information unused by workers and employers. I estimate the structural model, which also has flexible skill accumulation, by indirect inference. From simulation results on earnings dynamics, I find that the contribution of job shopping to average earnings growth is higher than previous estimates; also, individual heterogeneity in earnings growth is mostly explained by the process of resolving uncertainties. In the second chapter, which is joint work with Keunkwan Ryu, we estimate the effects of high school class size on college entrance exam scores, using Korean administrative data. For the identification, we exploit quasi-experimental variation in class size arising from distinct institutional settings in Korea: especially, students are separately educated by major from grade 11 with different class sizes between majors. By using multi-level differencing and instrumental variable techniques, we find the effects of high school class size reduction on the test scores are positive but small. In the third chapter, I examine the effects of life expectancy on retirement and related decisions. I construct a structural model which has a realistic description of complicated dynamic incentives facing the elderly, including Social Security. Furthermore, individual heterogeneity in survival beliefs are flexibly modeled, directly using subjective survival probabilities in the Health and Retirement Study (HRS) data. The estimated model suggests that many people in the data believed their wealth was over-annuitized; they would have chosen to work and save less if their average life expectancy had increased. This result partially explains the early retirement puzzle in the last century.

It is by now widely recognized that investment decisions play a major role in the determination of individual age-earnings profiles. The purpose of this paper is to present a simple life-cycle model of investment in human capital in which leisure choices are explicitly incorporated. In so doing, we integrate two previously disparate branches of life-cycle theory: models of labor supply with exogenous wages, and models of human capital formation with exogenous leisure. Of course, to accomplish this, we must posit utility maximization as the individual's goal rather than income maximization.

. . . I am convinced that it should occupy a high position on the desk of policymakers. . . This book constitutes a good state-of-the-art study in this field and paves the way for further research in this direction. Marie-Claire Villeval, Economic Record This attractive publication is carried out as a clear attempt to gain access to a wider audience, relaxing formal and technical details, which makes the lecture easier. . . An international comparison of literature or educational and labour experiences is provided in every contribution in the book, helping to obtain a wider perspective of the problems tackled. Carmen García and Julio López, Education Economics This book makes a novel contribution to economics of education in several key respects. It highlights a broad number of crucial factors over the individual s life cycle that underlie inequalities in education and in the labour market. . . It is amazing how limited our knowledge is about these interactions despite their high priority in national as well as EU-level policy-making. This is a timely book concerned with topics of high policy relevance. Moreover, the authors have well succeeded in their attempt to write "in a style that makes this work accessible to a wider audience", using the editor s words. It is most important that academics as well as politicians are made aware of the considerable knowledge gaps that still prevail in our understanding of the role of education and training for the individual s success or failure in school and in working life. Rita Asplund, The Research Institute of the Finnish Economy (ETLA), Finland In the last decade, changes occurring in the demand for skills have produced significant effect on the functioning of labour markets in Europe and elsewhere. The challenge posed by a knowledge based society for sustained growth has been at the centre of the European strategy for employment and has important implications for the design of labour market policies. This book brings together a wide range of contributions written by leading experts on key issues such as: schooling systems, transition from school to work and lifelong learning, thereby providing an essential reference for both researchers and policymakers. Claudio Lucifora, Università Cattolica, Italy Human Capital Over the Life Cycle synthesises comparative research on the processes of human capital formation in the areas of education and training in Europe, in relation to the labour market. The book proposes that one of the most important challenges faced by Europe today is to understand the link between education and training on the one hand and economic and social inequality on the other. The authors focus the analysis on three main aspects of the links between education and social inequality: educational inequality, differences in access to labour markets and differences in lifelong earnings and training. Almost all the stages in the life cycle are tracked from early childhood to stages late in the working life: firstly the characteristics and effects of schooling systems, then the transitions from school to work and, finally, human capital and the working career. Academics and researchers of European studies, labour economics and the economics of education will all find this novel and analytically sound book of interest, as will sociologists and policymakers in Europe.

We solve and estimate a dynamic model that allows agents to optimally choose their labor hours and consumption and that allows for both human capital accumulation and savings. Estimation results and simulation exercises indicate that the intertemporal elasticity of substitution is much higher than the conventional estimates and the downward bias comes from the omission of the human capital accumulation effect. The human capital accumulation effect renders the life-cycle path of the shadow wage relatively flat, even though wages increase with age. Hence, a rather flat life-cycle labor supply path can be reconciled with a high intertemporal elasticity of substitution.
