Characterizing Selection Bias Using Experimental Data

Abstract: This paper develops and applies semiparametric econometric methods to estimate the form of selection bias that arises from using nonexperimental comparison groups to evaluate social programs and to test the identifying assumptions that justify three widely-used classes of estimators and our extensions of them: (a) the method of matching; (b) the classical econometric selection model which represents the bias solely as a function of the probability of participation; and (c) the method of difference-in-differences. Using data from an experiment on a prototypical social program combined with unusually rich data from a nonexperimental comparison group, we reject the assumptions justifying matching and our extensions of that method but find evidence in support of the index-sufficient selection bias model and the assumptions that justify application of a conditional semiparametric version of the method of difference-in-difference. Fa comparable people and to appropriately weight participants and nonparticipants a sources of selection bias as conveniently measured. We present a rigorous defin bias and find that in our data it is a small component of conventially meausred it is still substantial when compared with experimentally-estimated program impa matching participants to comparison group members in the same labor market, givi same questionnaire, and making sure they have comparable characteristics substan the performance of any econometric program evaluation estimator. We show how t analysis to estimate the impact of treatment on the treated using ordinary obser

Regulation, Productivity and Growth: OECD Evidence

Abstract: Nicoletti and Scarpetta look at differences in the scope and depth of pro-competitive regulatory reforms and privatization policies as a possible source of cross-country dispersion in growth outcomes. They suggest that, despite extensive liberalization and privatization in the OECD area, the cross-country variation of regulatory settings has increased in recent years, lining up with the increasing dispersion in growth. The authors then investigate empirically the regulation-growth link using data that cover a large set of manufacturing and service industries in OECD countries over the past two decades and focusing on multifactor productivity (MFP), which plays a crucial role in GDP growth and accounts for a significant share of its cross-country variance. Regressing MFP on both economywide indicators of regulation and privatization and industry-level indicators of entry liberalization, the authors find evidence that reforms promoting private governance and competition (where these are viable) tend to boost productivity. In manufacturing the gains to be expected from lower entry barriers are greater the further a given country is from the technology leader. So, regulation limiting entry may hinder the adoption of existing technologies, possibly by reducing competitive pressures, technology spillovers, or the entry of new high-technology firms. At the same time, both privatization and entry liberalization are estimated to have a positive impact on productivity in all sectors. These results offer an interpretation to the observed recent differences in growth patterns across OECD countries, in particular between large continental European economies and the United States. Strict product market regulations - and lack of regulatory reforms - are likely to underlie the relatively poorer productivity performance of some European countries, especially in those industries where Europe has accumulated a technology gap (such as information and communication technology-related industries). These results also offer useful insights for non-OECD countries. In particular, they point to the potential benefits of regulatory reforms and privatization, especially in those countries with large technology gaps and strict regulatory settings that curb incentives to adopt new technologies. This paper - a product of the Social Protection Team, Human Development Network - is part of a larger effort in the network to understand what drives productivity growth.

Rank-Order Tournaments as Optimum Labor Contracts

Abstract: This paper analyzes compensation schemes which pay according to an individual's ordinal rank in an organization rather than his output level. When workers are risk neutral, it is shown that wages based upon rank induce the same efficient allocation of resources as an incentive reward scheme based on individual output levels. Under some circumstances, risk-averse workers actually prefer to be paid on the basis of rank. In addition, if workers are heterogeneous inability, low-quality workers attempt to contaminate high-quality firms, resulting in adverse selection. However, if ability is known in advance, a competitive handicapping structure exists which allows all workers to compete efficiently in the same organization.

Child Labor: Cause, Consequence, and Cure, with Remarks on International Labor Standards

Abstract: Should child labor be banned outright? Should the World Trade Organization be given the responsibility to discourage child labor using trade sanctions? The answer to this complicated problem depends on the economic milieu, says Basu. At least 120 million of the world's children aged 5 to 14 worked full-time in 1995, most of them under hazardous, unhygienic conditions, for more than 10 hours a day. This is an old problem worldwide but particularly so in Third World countries in recent decades. What has changed, with globalization, is our awareness of these child laborers. (The International Labour Organisation distinguishes between child work, which could include light household chores and could have some learning value, and child labor, a pejorative phrase.) By bringing together the main theoretical ideas, Basu hopes to encourage both more theoretical research and empirical work with a better theoretical foundation. Among other things, Basu observes that: ° The problem is most serious in Africa, where the child-labor participation rate is 26.2 percent. The rate is 12.8 percent in Asia. But since 1950, the trend is a decline in that participation rate worldwide. For most Latin American countries, the decline is notable but less marked than in Asia. In large parts of Africa, including Ethiopia, the problem has been extremely persistent, but even there the trend is downward. ° Child labor has not always been considered evil, and there is no consensus on why it began to decline. In some (not all) countries legislative acts declared it illegal, in some there were rules about compulsory education, and increasing prosperity generally made families less likely to experience poverty if their children weren't working. ° Mandating compulsory education is regarded as more effective than outlawing child labor, because attendance at school is easier to monitor, but some experts believe economic progress is the answer to the problem. The justification for many interventions is that the state is more concerned about the well-being of children than their parents are; Basu believes such an assumption to be wrong when child labor occurs as a mass phenomenon rather than as isolated abuse. Basu argues that, in some economies, the market for labor may exhibit multiple equilibria, with one equilibrium having low adult wage and a high incidence of child labor and another equilibrium exhibiting high adult wage and no child labor. The model is used to provide a framework for analyzing the role of international labor standards. This paper - a product of the Office of the Senior Vice President, Development Economics - is part of a larger effort in the Bank to promote understanding of the causes of child labor. The study was funded by the Bank`s Research Support Budget under the research project Literacy and Child Labor (RPO 683-07). The author may be contacted at kbasu@worldbank.org.

Is There a Glass Ceiling in Sweden

Abstract: Using data from 1998, we show that the gender log wage gap in Sweden increases throughout the wage distribution and accelerates in the upper tail of the distribution, which we interpret as a glass ceiling effect. Using earlier data, we show that the same pattern held at the beginning of the 1990's but not in the prior two decades. Further, we do not find this pattern either for the log wage gap between immigrants and non-immigrants in the Swedish labor market or for the gender gap in the U.S. labor market. Our findings suggest that a gender-specific mechanism in the Swedish labor market hinders women from reaching the top of the wage distribution. Using quantile regressions, we examine whether this pattern can be asribed primarily to gender differences in labor market characteristics or to gender differences in rewards to those characteristics. We estimate pooled quantile regressions with gender dummies, as well as separate quantile regressions by gender, and we carry out a decomposition analysis in the spirit of the Oaxaca-Blinder technique. Even after extensive controls for gender differences in age, education (both level and field), sector, industry, and occupation, we find that the glass ceiling effect we see in the raw data persists to a considerable extent.
