Identification and Estimation of Local Average Treatment Effects

Abstract: 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.

Who is Against Immigration? A Cross-Country Investigation of Individual Attitudes Toward Immigrants

Abstract: This paper empirically analyzes both economic and non-economic determinants of attitudes toward immigrants, within and across countries. The two individual-level survey data sets used, covering a wide range of developed and developing countries, make it possible to test for interactive effects between individual characteristics and country-level attributes. The paper identifies and investigates a strong empirical regularity concerning the relationship between individual skill and attitudes toward immigrants. I find that individuals with higher levels of skill are more likely to be pro-immigration in high per capita GDP countries and less likely in low per capita GDP countries. Additional results, based on a smaller sample of countries, suggest a labor-market explanation for this cross-country pattern. The variation across countries in the correlation between skill and preferences appears to be related to differences in the skill composition of natives relative to immigrants across destination economies. This finding is consistent with the predictions of the Heckscher-Ohlin model, in the absence of factor-price-insensitivity, and of the factor-proportions-analysis model. Finally, non-economic variables also appear to be correlated with immigration attitudes but they do not seem to alter significantly the results on the economic explanations.

Trade Liberalization, Intermediate Inputs and Productivity: Evidence from Indonesia

Abstract: This paper estimates the effects of trade liberalization on plant productivity. In contrast to previous studies, we distinguish between productivity gains arising from lower tariffs on final goods relative to those on intermediate inputs. Lower output tariffs can produce productivity gains by inducing tougher import competition whereas cheaper imported inputs can raise productivity via learning, variety or quality effects. We use Indonesian manufacturing census data from 1991 to 2001, which includes plant level information on imported inputs. The results show that the largest gains arise from reducing input tariffs. A 10 percentage point fall in output tariffs increases productivity by about 1%, whereas an equivalent fall in input tariffs leads to a 3% productivity gain for all firms and an 11% productivity gain for importing firms.

Children and Their Parents' Labor Supply: Evidence from Exogenous Variation in Family Size

Abstract: Although theoretical models of labor supply and the family are well developed, there are few credible estimates of key empirical relationships in the work-family nexus. This study uses a new instrumental variable, the sex composition of the first two births in families with at least two children, to estimate the effect of additional children on parents' labor supply. Instrumental variables estimates using the sex mix are substantial but smaller than the corresponding ordinary least squares (OLS) estimates. Moreover, unlike the OLS estimates, the female labor supply effects estimated using sex-mix instruments appear to be absent among more educated women and women with high-wage husbands. We also find that married women who have a third child reduce their labor supply by as much as women in the full sample, while there is no relationship between wives' child-bearing and husbands' labor supply. Finally results to estimates produced using twins to generate instruments. Estimates using twins instruments are very close to the estimates generated by sex-mix instruments, once the estimators are corrected for differences in the ages of children whose birth was caused by the instruments. The estimates imply that the labor supply consequences of child-bearing disappear by the time the child is about 13 years old.

Temporary Jobs: Stepping Stones or Dead Ends?

Abstract: In Britain about 7% of male employees and 10% of female employees are in temporary jobs. In contrast to much of continental Europe, this proportion has been relatively stable over the 1990s. Using data from the British Household Panel Survey, we find that temporary workers report lower levels of job satisfaction, receive less work-related training, and are less well-paid than their counterparts in permanent employment. However, there is evidence that fixed-term contracts are a stepping stone to permanent work. Women (but not men) who start in fixed-term employment and move to permanent jobs fully catch up to those who start in permanent jobs.
