A Treatise on the Family. G. S. Becker. Cambridge, MA: Harvard University Press. 1981. Gary Becker is one of the most famous and influential economists of the second half of the 20th century, a fervent contributor to and expounder of the University of Chicago free-market philosophy, and winner of the 1992 Nobel Prize in economics. Although any book with the word "treatise" in its title is clearly intended to have an impact, one coming from someone as brilliant and controversial as Becker certainly had such a lofty goal. It has received many article-length reviews in several disciplines (Ben-Porath, 1982; Bergmann, 1995; Foster, 1993; Hannan, 1982), which is one measure of its scholarly importance, and yet its impact is, I think, less than it may have initially appeared, especially for scholars with substantive interests in the family. This book is, its title notwithstanding, more about economics and the economic approach to behavior than about the family. In the first sentence of the preface, Becker writes "In this book, I develop an economic or rational choice approach to the family." Lest anyone accuse him of focusing on traditional (i.e., material) economics topics, such as family income, poverty, and labor supply, he immediately emphasizes that those topics are not his focus. "My intent is more ambitious: to analyze marriage, births, divorce, division of labor in households, prestige, and other non-material behavior with the tools and framework developed for material behavior." Indeed, the book includes chapters on many of these issues. One chapter examines the principles of the efficient division of labor in households, three analyze marriage and divorce, three analyze various child-related issues (fertility and intergenerational mobility), and others focus on broader family issues, such as intrafamily resource allocation. His analysis is not, he believes, constrained by time or place. His intention is "to present a comprehensive analysis that is applicable, at least in part, to families in the past as well as the present, in primitive as well as modern societies, and in Eastern as well as Western cultures." His tone is profoundly conservative and utterly skeptical of any constructive role for government programs. There is a clear sense of how much better things were in the old days of a genderbased division of labor and low market-work rates for married women. Indeed, Becker is ready and able to show in Chapter 2 that such a state of affairs was efficient and induced not by market or societal discrimination (although he allows that it might exist) but by small underlying household productivity differences that arise primarily from what he refers to as "complementarities" between caring for young children while carrying another to term. Most family scholars would probably find that an unconvincingly simple explanation for a profound and complex phenomenon. What, then, is the salient contribution of Treatise on the Family? It is not literally the idea that economics could be applied to the nonmarket sector and to family life because Becker had already established that with considerable success and influence. At its core, microeconomics is simple, characterized by a belief in the importance of prices and markets, the role of self-interested or rational behavior, and, somewhat less centrally, the stability of preferences. It was Becker's singular and invaluable contribution to appreciate that the behaviors potentially amenable to the economic approach were not limited to phenomenon with explicit monetary prices and formal markets. Indeed, during the late 1950s and throughout the 1960s, he did undeniably important and pioneering work extending the domain of economics to such topics as labor market discrimination, fertility, crime, human capital, household production, and the allocation of time. Nor is Becker's contribution the detailed analyses themselves. Many of them are, frankly, odd, idiosyncratic, and off-putting. …

The power of feedback.

We investigate conditions sufficient for identification of average treatment effects using instrumental variables. First we show that the existence of valid instruments is not sufficient to identify any meaningful average treatment effect. We then establish that the combination of an instrument and a condition on the relation between the instrument and the participation status is sufficient for identification of a local average treatment effect for those who can be induced to change their participation status by changing the value of the instrument. Finally we derive the probability limit of the standard IV estimator under these conditions. It is seen to be a weighted average of local average treatment effects.

This paper provides an introduction and “user guide” to Regression Discontinuity (RD) designs for empirical researchers. It presents the basic theory behind the research design, details when RD is likely to be valid or invalid given economic incentives, explains why it is considered a “quasi-experimental” design, and summarizes different ways (with their advantages and disadvantages) of estimating RD designs and the limitations of interpreting these estimates. Concepts are discussed using examples drawn from the growing body of empirical research using RD. ( JEL C21, C31)

Relying on a natural experiment consisting in 130 competitions for promotion to associate and full professor in Italian universities, we analyse whether gender discrimination is affected by the gender of evaluators. We examine the probability of success of each candidate in relation to the committee gender composition, exploiting the random assignment of evaluators and controlling for candidates’ scientific productivity and a number of individual characteristics. We find that female candidates are less likely to be promoted when the committee is composed exclusively of males, while the gender gap disappears when the candidates are evaluated by a mixed-sex committee.

Gender Discrimination and Evaluators’ Gender: Evidence from Italian Academia

In this paper sport data are used to study the effects of manager replacement on firm performance. Using match results of the major Italian soccer league (“Serie A”) we analyze the effects of coach (manager) changes in terms of team performance. From our preliminary estimates, including year and team fixed effects, it emerges that changing the coach produces a positive effect on a number of measures of team performance. However, this effect turns out to be statistically insignificant once we take into account the fact that the firing of a coach is not an exogenous event, but it is triggered by a “dip” in team performance. Using as an instrument for coach change the number of remaining matches in the season (which is a proxy for the residual length of the coach contract) Two-Stages Least Squares estimations do not show any significant effect of coach change on team performance.

Does the peer effect vary with the field of study? Using data from a middle-sized public university located in southern Italy and exploiting the random assignment of first-year students to college accommodation, we find that roommate peer effects for freshmen enrolled in the hard sciences are positive and significantly larger than for freshmen enrolled in the humanities and social sciences.We present a simple theoretical model which suggests that the uncovered differences between fields in the size of the peer effect could plausibly be generated by between-field variation in labor market returns, which affect optimal student effort. (JEL I21, Z13, J24) I. INTRODUCTION Understanding the nature and importance of peer group effects in education is crucial for education policy. Peer effects are relevant for school choice, tracking, affirmative action, selective admissions, and the sources of school quality. Empirical research which seeks to estimate the existence, size, and non-linearity of peer effects has run into several problems, including the self-selection, reflection, and correlated effects described by Manski (1993). Following Sacerdote (2001) and Zimmerman (2003), a popular approach in this literature has been to investigate roommate peer effects, because in a number of universities and colleges the allocation of students to rooms can be argued

Peer effects in higher education: does the field of study matter?

Many incentive contracts are based on subjective evaluations and contractual disputes depend on judges’ decisions. However, subjective evaluations raise risks of favouritism and distortions. Sport contests are a fruitful field for testing empirically theories of incentives. In this paper the behaviour of the referees in the Italian soccer (football) league (“Serie A”) is analyzed. Using data on injury (or extra) time subjectively assigned by the referee at the end of the match and controlling for factors which may influence it (players substitutions, yellow and red cards, penalty kicks, etc.), we show that referees are biased in favour of home team, in that injury time is significantly greater if home teams are losing. The refereeing bias increases greatly when there is no running track in the stadium and the crowd is close to the pitch. Following the 2006 “Serie A” scandal we test whether favouritism emerges towards teams suspected of connections with referees finding that these teams obtain favourable decisions. Social pressure by the crowd attending the match however appears to be the main cause of favouritism.
