  • 2005 Mincer Award
    Mincer Award Winners 2005: Orley Ashenfelter is one of the two winners of the 2005 Society of Labor Economists’ Jacob Mincer prize honoring lifetime achievements in the field of labor economics. Over the course of a distinguished career, Orley Ashenfelter has had tremendous influence on the development of modern labor economics. His early work on trade unions brought neoclassical economics to bear on a subject that had been the domain of traditional institutionally-oriented industrial relations specialists. As labor supply emerged as one of the most important subjects in the new field, Ashenfelter showed (in work with James Heckman) that neoclassical theory could be applied to decision making within the family. In his Frisch-prize winning 1980 article, Ashenfelter developed a theoretical and empirical framework for distinguishing between voluntary and involuntary unemployment. Orley was also involved in the income maintenance experiments, the first large-scale social experiments. In 1972 Orley served as Director of the Office of Evaluation of the U.S. Dept. of Labor and became deeply interested in the problem of program evaluation. This focus led him to emphasize developing credible and transparent sources of identification through strategies such as the collection of new data, difference-in-difference designs, and exploiting “natural experiments.” In the 1990s, Orley turned to measuring the returns to education. In a series of studies using new data on twins, Ashenfelter (with Alan Kreuger and Cecilia Rouse) suggested that OLS estimates of the returns to schooling were biased downward to a significant degree. Orley has also had a significant impact on the development of empirical law and economics in recent years.

  • Essays on Time Allocation
    Tesi Doctoral Essays on Time Allocation A thesis presented by Jorge González Chapela to Departament d’Economia i Empresa Universitat Pompeu Fabra Barcelona May 2004 “It is merely human nature that we overrate the importance of our own types of research and underrate the importance of the types that appeal to others. Perhaps it is not too much to say that we should never do what we are doing, both in science and in other pursuits of life, if we did not do this.” Joseph A. Schumpeter ii Acknowledgments First of all, I want to thank Xavier Sala i Martín. Not only his support and infinite patience when progress was stagnant were essential to the comple- tion of this thesis, but also because he showed me that the way to become a rigorous scientist is paved with intellectual curiosity, clear mind, and hard work. M’esforçare per estar a la alçada del teu magisteri, Xavier. I owe a lot (a lot!) to Ernesto Villanueva. His guidance, patience, encouragement, and friendship have been fundamental to arrive here. Gracias, Ernesto. Throughout the Ph.D., Antonio Ciccone, Jaume García, and Ángel López have deeply contributed to develop my skills as an economist with their brilliant lectures, fruitful discussions, and appealing challenges. A los tres, ¡gracias! In some way or another, may other people have intellectually shaped this thesis—my teachers at Universidade de Santiago de Compostela and Universitat Pompeu Fabra, my class mates,... To all of them, my gratitude. Ademais de débedas intelectuais, unha tese leva consigo unha morea de renuncias. Pra chegar eiquí, tiven de renuncia-la compaña dos meus pais e irmán—vós sóde-lo todo pra min—, dos meus bos amigos—¡cantas cousas puidemos ter feito xuntos!—, e de moitas outras persoas—vivas ou xa mortas— que me aledan a vida.

  • In 2012 the Society of Labor Economists Presented the Sherwin Rosen Award to Marianne Bertrand, for Outstanding Contributions in the Field of Labor Economics
    In 2012 the Society of Labor Economists presented the Sherwin Rosen Award to Marianne Bertrand, for outstanding contributions in the field of labor economics. Bertrand received her PhD from Harvard in 1998. She is the Chris P. Dialynas Professor of Economics and Richard N. Rosett Faculty Fellow at the Booth School of Business at the University of Chicago. She is a research associate of the National Bureau of Economic Research and a coeditor of the American Economic Review. Her work has covered a number of topics including racial discrimination, CEO pay and incentives, the effects of regulation on employment, and household finance. Her research in these areas has been published widely, including numerous research articles in the Quarterly Journal of Economics, the Journal of Political Economy, and the American Economic Review, as well as several public policy journals. Bertrand has made outstanding contributions to several areas of labor economics. A first area concerns the connection between product market competition and labor market outcomes. Her Quarterly Journal of Economics (2002) article with Francis Kramarz, “Does Entry Regulation Hinder Job Creation? Evidence from the French Retail Industry,” looks at whether entry regulation in the French retail industry can explain the low rates of job creation observed in that sector over the last 25 years. Since the early 1970s, the French government has required regional zoning board approval for the creation or extension of any large retail store. Using a unique database that provides time and regional variation in boards' approval decisions, they show that this requirement created barriers to entry in the retail sector, and weakened employment growth in the retail industry.

Among other things, the authors consider some relevant facets of the social and institutional environments in which the poor interact, and they review some behavioral patterns that are likely to arise in these contexts. A behaviorally more informed perspective can help make sense of what might otherwise be considered “puzzles” in the economic comportment of the poor. A behavioral analysis suggests that substantial welfare changes could result from relatively minor policy interventions, and insightful marketing may provide much needed help in the design of such interventions.

  • Preschool Television Viewing and Adolescent Test Scores: Historical Evidence from the Coleman Study
    PRESCHOOL TELEVISION VIEWING AND ADOLESCENT TEST SCORES: HISTORICAL EVIDENCE FROM THE COLEMAN STUDY MATTHEW GENTZKOW AND JESSE M. SHAPIRO We use heterogeneity in the timing of television’s introduction to different local markets to identify the effect of preschool television exposure on standardized test scores during adolescence. Our preferred point estimate indicates that an additional year of preschool television exposure raises average adolescent test scores by about 0.02 standard deviations. We are able to reject negative effects larger than about 0.03 standard deviations per year of television exposure. For reading and general knowledge scores, the positive effects we find are marginally statistically significant, and these effects are largest for children from households where English is not the primary language, for children whose mothers have less than a high school education, and for nonwhite children. I. INTRODUCTION Television has attracted young viewers since broadcasting be- gan in the 1940s. Concerns about its effects on the cognitive devel- opment of young children emerged almost immediately and have been fueled by academic research showing a negative association between early-childhood television viewing and later academic achievement.1 These findings have contributed to a belief among the vast majority of pediatricians that television has “negative effects on brain development” of children below age five (Gentile et al. 2004). They have also provided partial motivation for re- cent recommendations that preschool children’s television view- ing time be severely restricted (American Academy of Pediatrics 2001). According to a widely cited report on media use by young * We are grateful to Dominic Brewer, John Collins, Ronald Ehrenberg, Eric Hanushek, and Mary Morris (at ICPSR) for assistance with Coleman study data, and to Christopher Berry for supplying data on school quality.

  • Learning, Career Paths, and the Distribution of Wages†
    American Economic Journal: Macroeconomics 2019, 11(1): 49–88 https://doi.org/10.1257/mac.20170390 Learning, Career Paths, and the Distribution of Wages† By Santiago Caicedo, Robert E. Lucas Jr., and Esteban Rossi-Hansberg* We develop a theory of career paths and earnings where agents organize in production hierarchies. Agents climb these hierarchies as they learn stochastically from others. Earnings grow as agents acquire knowledge and occupy positions with more subordinates. We contrast these and other implications with US census data for the period 1990 to 2010, matching the Lorenz curve of earnings and the observed mean experience-earnings profiles. We show the increase in wage inequality over this period can be rationalized with a shift in the level of the complexity and profitability of technologies relative to the distribution of knowledge in the population. JEL D83, E24, J24, J31 ( ) his paper develops a new model of an economy that generates sustained pro- Tductivity growth. One distinctive feature of the model is that all knowledge in the economy is held by the individual people who comprise it: there is no abstract technology hovering above them in the ether. A second feature, necessarily involv- ing heterogeneous labor, is a kind of complementarity in production involving peo- ple with different skill levels: the marginal product of any one person is contingent on the people he works with. A third feature, closely related to the second, is that improvements over time in individual skill levels depend on imitation or stimulation or inspiration from other people in the economy. All growth is taken to arise from this force.

    Technical Paper Series Congressional Budget Office Washington, DC MODELING LONG-RUN ECONOMIC GROWTH Robert W. Arnold Congressional Budget Office Washington, D.C. 20515 [email protected] June 2003 2003-4 Technical papers in this series are preliminary and are circulated to stimulate discussion and critical comment. These papers are not subject to CBO’s formal review and editing processes. The analysis and conclusions expressed in them are those of the author and should not be interpreted as those of the Congressional Budget Office. References in publications should be cleared with the author. Papers in this series can be obtained from www.cbo.gov. Abstract This paper reviews the recent empirical literature on long-run growth to determine what factors influence growth in total factor productivity (TFP) and whether there are any channels of influence that should be added to standard models of long-run growth. Factors affecting productivity fall into three general categories: physical capital, human capital, and innovation (including other factors that might influence TFP growth). Recent empirical evidence provides little support for the idea that there are extra-normal returns to physical capital accumulation, nor is there solid justification for adding a separate channel of influence from capital to TFP growth. The paper finds evidence that human capital—as distinct from labor hours worked—is an important factor for growth but also that there is not yet a consensus about exactly how it should enter the model. Some argue that human capital should enter as a factor of production, while others argue that it merely spurs innovation. The forces governing TFP growth are not well understood, but there is evidence that R&D spending is a significant contributor and that its benefit to society may exceed its benefit to the company doing the spending—that is, it is a source of spillovers.

  • Professor Orley Ashenfelter Is the World's Leading Researcher in The
    Citation read out at the Royal Society of Edinburgh on 24 March 2005 upon the election of Professor Orley Ashenfelter to the Fellowship of the Royal Society of Edinburgh. Professor Orley Ashenfelter is the Joseph Douglas Green 1895 Professor of Economics at Princeton University. He is the world's leading researcher in the field of labour economics, and has also made major contributions to research in the field of econometrics and law and economics. As Director of the Office of Evaluation of the US Department of Labour in 1972, Professor Ashenfelter began the work that is now widely recognized as the field of "quantitative social program evaluation." His influential work on the econometric evaluation of government retraining programs led to the systematic development of rigorous methods for the evaluation of many social programs. Professor Ashenfelter is also regarded as the originator of the use of so-called "natural experiments" to infer causality about economic relationships. This approach, now becoming universal in all the social sciences, is associated with Princeton University's Industrial Relations Section, of which Professor Ashenfelter was Director. He edited the Handbook of Labour Economics, and is currently Editor of the American Law and Economics Review. His current research includes the evaluation of the effect of schooling on earnings, the cross- country measurement of wage rates, and many other issues related to the economics of labour markets. His further interests include the market for fine wine. Several of his contributions to the economics research literature have been motivated by and reflect this interest. Professor Ashenfelter is a frequent visitor to the UK, and has been visiting Professor at the London School of Economics and the University of Bristol.
