Does productivity increase with density? We revisit the issue usingFrench wage and TFP data. To deal with the ‘endogenous quantity of labour' bias (i.e., urban agglomeration is consequence of high local productivity rather than a cause), we take an instrumental variable approach and introduce...

Using both reduced-form and structural approaches, the spectrum of policy recommendations that can be drawn from empirical economic geography is pretty large. Reduced-form approaches allow the researchers to consider many variables that impact on regional disparities, as long as they are careful...

We develop a method based on the use of polar coordinates to investigate the existence of moments for instrumental variables and related estimators in the linear regression model. For generalized IV estimators, we obtain familiar results. For JIVE, we obtain the new result that this estimator...

This article examines the relationship between migrants' remittances and the prevalence of child labor by using a large sample of developing countries. In particular, we investigate whether the inflows of remittances help to offset the effects of financial constraints and income shocks on the...

Measures of urban productivity are typically positively associated with city population. But is this relationship causal? We discuss the main sources of bias in the proper identification of agglomeration effects. We also assess a variety of solutions that have been proposed in the literature to...

According to the literature, the effect of remittances on income inequality in origin countries of migrants is not clear, whatever empirical approach is used. Aiming at clearing up this ambiguity, some authors took into account the historical, social or economic context of the home countries...

In order to test for the effect of public housing occupancy on unemployment, we estimate a simultaneous probit model of unemployment and public housing. On a first sample, we instrument public housing with the gender composition of children. On a second sample, the instrument is the share of...

This paper shows that living in public housing has no effect on the probability of being unemployed in France, once we account for the endogeneity of public housing. We estimate a simultaneous probit model of unemployment and public housing. On a first sample for Lyon, we instrument public...
