A positive relationship between firm size and product diversification is a long-standing stylized fact. However, so far there is no appropriate theoretical model to explain the underlying forces of this observation. This paper analyzes an oligopoly model with asymmetric multiproduct frms, which...

Is human capital a robust predictor of good institutions? Using a new institutional quality measure, the International Property Rights Index (IPRI), we find that cognitive skill measures are significant, robust, and large in magnitude. We use two databases of cognitive skills: estimates of...

This paper investigates the question whether long-term human capital outcomes are affected by the duration of maternity leave, i.e. by the time mothers spend at home with their newborn before returning to work. Employing RD and difference-in-difference approaches, this paper exploits an...

Following the collapse of planning, new small and medium-sized firms rapidly emerged in all transition economies. Using firm level data, we investigate the interaction between the widespread opportunities for new business activities such firms faced and their business environment. The business...

Why are better educated and more risk-friendly persons more mobile across regions? To answer this question, we use micro data on internal migrants from the German Socio-Economic Panel (SOEP) 2000–2006 and merge this information with a unique proxy for region-pair-specific cultural distances...

How do population ageing shocks affect the long-run macroeconomic performance of an economy? To answer this question we build a general equilibrium overlapping generations model of a closed economy featuring endogenous factor prices. Finitely-lived individuals are endowed with perfect foresight...

Based on a unique composite dataset measuring heterogeneous sports participation, labour market outcomes and local facilities provision, this paper examines for the first time the association between different types of sports participation on employment and earnings in England. Clear...

Mobility of highly-skilled workers affects and is affected by labor market conditions, taxes, and other policies. This paper documents the demographic and fiscal importance of international migration, especially in aging societies, reviews the efficiency and distributional effects of mobility,...

In this paper we conduct a quantitative analysis of a number of stylized educational loan systems. We develop a stochastic general equilibrium model of a closed economy with a competitive firm sector and a government that levies taxes and administers educational loans. Individuals are...
