Results based on a sample of Canadian households challenge the findings of most studies which show significant negative effects of schooling on the fertility of women under the age of 45. This is due to the application of methods to an optimization model which distinguish between those...

We argue in this paper that it is more feasible to use binary variables and logistic regression analyses in the assessments of AIDS incidents o or other similar researches in social science. Thus, even in measuring disease persistence we can reach solid and comprehensive results. Statistical...

The founding directors of newly incorporated companies bring social capital (reputation, networks, business relationships) and human capital (task-related, professional and director experience) to a new venture and founding boards vary in degree of heterogeneity (size, diversity, turnover). This...

We consider identification in a "generalized regression model" (Han, 1987) for panel settings in which each observation can be associated with a "group" whose members are subject to a common unobserved shock. Common examples of groups include markets, schools or cities. The model is fully...

Improved household accessibility to credit is identified as a significant determinant of intra-household re-allocation of labour resources with important implications for productivity, income, and poverty status. However, credit accessibility could also have wider impacts on poverty if it leads...

We use a panel of Czech firms to enhance existing literature where the dependent variable is foreign ownership. In our estimation, we control for endogeneity and unobserved effects using standard methods complemented by tests for heterogenous Granger-causality. We also model foreign ownership as...

This paper proposes a novel two-stage approach to modeling health-related quality-of-life (HRQoL) outcomes. The approach allows a patient-centered interpretation by estimating regression coe fficients based on the multi-dimensional HRQoL profi le, but maintains the parsimony of the...

This paper investigates the determinants of firm-sponsored training which result from the Acemoglu-Pischke model (APM) empirically using German firm-level data on apprenticeship training. Acemoglu and Pischke (1999a, 1999b) demonstrate that wage compression may encourage employers to offer and...

We study a nonlinear two-way fixed effects panel model that allows for unobserved individual heterogeneity in slopes (interacting with covariates) and (unknown) flexibly specified link function. The former is particularly relevant when the researcher is interested in the distributional causal...

Many oligopoly theories predict that there will be a positive correlation between market size and the equilibrium number of firms, and some also imply that competition is more intense in larger markets. We test these predictions with a sample of 535 driving schools in 249 markets. With an...
