Financial constraints affect firms’ financial and productive decisions generating substantial macroeconomic implications in terms of investment, economic growth, inflation and income distribution. Despite its relevance, financial constraints are not directly observable. However, empirically...

The properties of classical panel data estimators including fixed effect, first-differences, random effects, and generalized method of moments-instrumental variables estimators in both static as well as dynamic panel data models are investigated under sample selection. The correlation of the...

The empirical identification of non-linearities in investment relies on how investment is assumed to be separated into various regimes. Using German establishment-level panel data, we estimate a two-regime model of replacement and expansion investment which allows us to observe regime...

In the paper is considered identification of coefficients in equations explaining a continuous variable, say the number of sickness absence days of an individual per year, by cohort, time and age, subject to their definitional identity. Extensions of a linear equation to polynomials, including...

Identification of equations explaining a continuous variable, e.g., the length of sickness absence spells, by age, cohort and time (ACT), subject to their definitional identity is reconsidered. Various extensions of a linear equation to polynomials are explored. If no interactions between the...

This paper develops a nonparametric methodology for treatment evaluation with multiple outcome periods under treatment endogeneity and missing outcomes. We use instrumental variables, pre-treatment characteristics, and short-term (or intermediate) outcomes to identify the average treatment...

We study the efficiency of state stimulating methods to attract investments into the timber industry development by logit, probit and tobit panel data models. Оur estimates reveal the most efficient stimulating methods of attracting investments into the wood sector. The approach can be...

This study develops a two-step estimator for a panel data Tobit model based on taking first-differences of the equation of interest, under conditional mean independence assumptions.The necessary correction terms are non-standard and a substantial part is therefore devoted to the formal...
