This paper develops a three stage oligopoly game for R&D cooperation, R&D expenditure and product market competition. In the first stage, firms decide whether or not to conduct R&D in cooperation with other firms. In the second stage the level of R&D investment is determined. Finally, firms...

Trading under limited pre-trade transparency becomes increasingly popular on financial markets. We provide first evidence on traders' use of (completely) hidden orders which might be placed even inside of the (displayed) bid-ask spread. Employing TotalView-ITCH data on order messages at NASDAQ,...

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...

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...

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...

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...

Striving for gender equality presents major challenges but the benefits are vast, ranging from reduced conflict, both within and between communities, to higher economic growth. Unfortunately, Israel's gender wage gap remains one of the highest among developed countries, despite a growing reverse...

Conventional wisdom suggests that unemployment benefits create a stronger geographic attachment by lowering the willingness of the unemployed to accept job offers. We assess empirically the effect of benefits on geographic labour mobility using individual data from the European Community...

This study applies count data estimation techniques to investigate the fertility adjustment of immigrants in the destination country. Data on completed fertility are taken from the 1996 wave of the German Socioeconomic Panel (GSOEP). While the economic literature stresses the role of prices and...
