In this paper, we propose a test for bivariate normality in imperfectly observed models, based on the information matrix test for censored models with bootstrap critical values. In order to evaluate its properties, we run a comprehensive Monte Carlo experiment, in which we use the bivariate...

The commonly-used version of the double-hurdle model rests on a rather restrictive set of statistical assumptions, which are very seldom tested by practitioners, mainly because of the lack of a standard procedure for doing so, although violation of such assumptions can lead to serious modelling...

In this paper, we run a Monte Carlo analysis of the finite-sample performance of an Information Matrix Test put forward by Smith (1985) for bivariate censored models. We use the bivariate probit model and Heckman selection model as examples.;Approximating the finite-sample distribution of this...

This paper presents the Gretl function package DPB for estimating dynamic binary models with panel data. The package contains routines for the estimation of the random-effects dynamic probit model proposed by Heckman (1981b) and its generalisation by Hyslop (1999) and Keane and Sauer (2009) to...

In this paper, we analyze the higher education choices of Italian secondary school leavers by addressing the roles of university quality, costs and geographical distance to the institution as well as the relationship between students’ choices and their personal and household’s attributes,...

Since the seminal paper by Heckman (1974), the sample selection model has been an essential tool for applied economists and arguably the most sensitive to sources of misspecification among the standard microeconometric models involving limited dependent variables. The need for alternative...

The analysis of performance indicators of university students has become of wide interest expecially in Italy where, over the last few decades, graduation rates have been well below the average of both European and OECD countries. This paper proposes an alternative method to jointly estimate the...

This paper examines the enrolment decision and the university choice of Italian secondary school graduates. We extend previous analyses by means of a theoretical model where student's choices depend on both universities attributes and individual characteristics. Empirical evidence of theoretical...

We present a simple theory and an empirical test for state dependence in firm access to credit. We estimate a first-order Markov model of credit restriction with sample selection that makes it possible to estimate state dependence in the presence of feedback effects and observed and unobserved...
