What Works for Adolescent Reproductive Health: Lessons from Experimental Evaluations of Programs and Interventions

This Child Trends fact sheet reviews evaluated programs that focus on adolescent reproductive health. Among the findings: Many different types of programs have been shown to positively affect reproductive health outcomes. Not only school- and community-based sex education programs, but also clinic-based programs, youth development programs, service-learning programs, early childhood programs, and programs for young mothers have been found to be effective. Comprehensive sex education can improve adolescent reproductive health. Of the 21 comprehensive sex education programs that have been experimentally evaluated, 11 had a significant positive impact on the behavior of the youth studied or important subgroups of the sample. No abstinence-only interventions have yet been shown to positively affect any behavioral outcomes. Six abstinence-only interventions have had their impacts on behavioral outcomes experimentally evaluated. None has had an impact on initiation of sexual intercourse, frequency of sexual activity, number of sexual partners, use of condoms, use of contraceptives, pregnancies, births, or STD contraction. None of these six abstinence-only interventions have been shown to negatively affect any behavioral outcomes, either. In particular, in spite of their exclusive focus on abstinence, none have served to significantly decrease condom or contraceptive use. The fact sheet includes a table that shows whether the evaluated programs were found to work, not proven to work, or had mixed findings

Gender differences in self-employment

This paper examines the factors that influence transitions into self-employment, paying particular attention to gender differences. We find that: (i) men are more responsive to the wage differential between wage/salaried employment and self-employment; (ii) liquidity constraints are more important for men; and (iii) the link between father’s self-employment status and the probability of self-employment is stronger for men. Taken together, these results suggest that, for women, self-employment is a closer substitute for part-time work and labour market inactivity than it is for men. We attribute such differences to the different labour market opportunities and occupational strategies of women.Employment (Economic theory) ; Labor market ; Germany

Low-powered incentives

We study low-powered incentives in a model that captures important features of workplaces in which incentive-pay approaches are minimally relevant. Our motivation is that incentive pay, while not rare, is clearly far less common than are agency problems: many firms with agency problems nonetheless pay fixed compensation and offer continued employment to all but those workers judged "unsatisfactory" according to largely subjective criteria. We find that low-powered incentives can achieve efficient outcomes in simple workplaces and function surprisingly well even when the environment is characterized by unobservable performance heterogeneity and a high degree of complementarity among workers.Wages

Foreign direct investment in China: a spatial econometric study

Foreign direct investment (FDI) began to flow into China with advent of reforms in 1978. Following a period of relatively slow growth, FDI inflows to China picked up after 1990, as China surpassed every other nation but the United States in attracting foreign investment. In particular, coastal regions of China have received the bulk of FDI inflows to the country. In this paper, we use province-level data to explain the pattern of FDI location across China. We build upon previous research, introducing new potential determinants, using more recent FDI data, and incorporating spatial econometric techniques. In doing so, we test for potential econometric problems arising from the spatial pattern of the data, and correct for them by running more appropriate models. We find that economic size, labor productivity and coastal location attract FDI, while higher wages and illiteracy rates deter it. The transportation infrastructure variables we try are not found to have statistically significant relationships with the level of FDI inflows across provinces.China ; Investments, Foreign ; Econometrics

European business cycles: new indices and analysis of their synchronicity

This article presents a new type of business-cycle index that allows for cycle-to-cycle comparisons of the depth of recessions within a country, cross-country comparisons of business-cycle correlation and simple aggregation to arrive at a measure of a European business cycle. The paper examines probit-type specifications of binary recession/expansion variables in a Gibbs-sampling framework, wherein it is possible to incorporate time-series features to the model, such as serial correlation, heteroskedasticity and regime switching. The data-augmentation implied by Gibbs sampling generates posterior distributions for a latent coincident business-cycle index and extracts information from indicator variables, such as the slope of the yield curve. Sub-sample correlations between an aggregated ``Europe'' index and the national business-cycle indices from France, Germany, Italy are consistent with the claim that the European economies are becoming more harmonized over time, but there is no guarantee that this pattern will hold in the future.Business cycles ; European Economic Community

Controlling for heterogeneity in gravity models of trade and integration

This paper compares various specifications of the gravity model of trade as nested versions of a general specification that uses bilateral country-pair fixed effects to control for heterogeneity. For each specification, we show that the a theoretical restrictions to obtain them from the general model are not supported statistically. Because the gravity model has become the ‘workhorse’ baseline model for estimating the effects of international integration, this has important empirical implications. In particular, we show that, unless heterogeneity is accounted for correctly, gravity models can greatly overestimate the effects of integration on the volume of trade.International trade
