This paper deals with the question whether exclusion restrictions on the exogenous regressors are necessary to identify two equation probit models with endogenous dummy regressor. We show that Wilde (2000)’s criterion is insufficient for (point) identification.

This paper deals with the question whether exclusion restrictions on the exogenous regressors are necessary to identify two equation probit models with endogenous dummy regressor. Contradictory opinions have been exposed in the literature on the necessity of an exclusion restriction. Wilde...

Using a data set that covers all Portuguese mainland municipalities for the period 1979-2005, this study performs an empirical analysis of the economic determinants of Mayors' choice to run for another term. The literature on the subject is mainly centered on the United States and, as far as we...

This paper uses firm level survey data from Portugal to investigate how firms adjust their labour costs in the presence of wage rigidities. We document that Portuguese firms, besides reducing employment or freezing nominal base wages, also make frequent use of other cost-cutting strategies, like...

This paper introduces a new and simple decomposition method for a binary choice model that is equivalent to the Blinder-Oaxaca decomposition analysis for wage differentials. The decomposition method is first developed for a single probit model and later generalized to a simultaneous equations...

The bivariate probit model is frequently used for estimating the eff ect of an endogenous binary regressor (the "treatment") on a binary health outcome variable. This paper discusses simple modifi cations that maintain the probit assumption for the marginal distributions while introducing...

We study practice variation in scheduling of caesarean section (CS) delivery across public and private hospitals in Italy. Adopting a novel perspective, we look at the role played by patients’ preferences for the treatment. The recursive probit model is revisited as a useful tool to assess the...

This study considers heckit-type approximations useful for a number of different trivariate probit models. They are simple to use and have no convergence problems like full maximum likelihood. Simulations show that a heckit and a least squares approximation perform as well as the trivariate...

Economic theory suggests that financing constraints may occur due to capital market imperfections. These particularly affect investments in innovation projects as such projects are typically characterized by a high degree of uncertainty, complexity and specificity. Financing innovation...
