Within the framework of Monte Carlo experiments, this paper systematically compares different versions of the simulated z-test (using the GHK simulator) in one- and multiperiod multinomial probit models. One important finding is that, in the flexible probit models, the tests on parameters of...

Employee involvement and financial incentives are often praised as effective means for increasing firm productivity. We assess the productivity effects of these human resource practices by accounting for the main sources of estimation bias - unobserved heterogeneity and endogeneity - and by...

We test for precautionary saving and excess sensitivity of consumption to predicted income growth using a 1989-93 panel survey of Italian households that has measures of subjective income and inflation expectations. These expectations provide a powerful instrument for predicting income growth....

We study the determinants that affect the capacity of ports to attract cruise ships in Spain. The conclusion is that the likelihood of having cruise traffic is linked to ports located in populous areas and close to large airports, ports not specialized in container traffic but sharing facilities...

In this article, I present ivtreatreg, a command for fitting four different binary treatment models with and without heterogeneous average treatment effects under selection-on-unobservables (that is, treatment endogeneity). Depending on the model specified by the user, ivtreatreg provides...

This overview describes the development of methods for empirical research in the field of labor economics during the past four decades. This period is characterized by the use of micro data to answer policy relevant research question. Prominent in the literature is the search for exogenous...
