This paper estimates the effects of the EU enlargements in the 2000s for trade in parts and components and trade in final goods separately. A gravity model is applied to disaggregated trade data over the period 1999-2009 for trade between EU and OECD countries. The estimation approach accounts...

This paper introduces dynamics in the R&D to innovation and innovation to productivity relationships, which have mostly been estimated on cross-sectional data. It considers four nonlinear dynamic simultaneous equations models that include individual effects and idiosyncratic errors correlated...

We estimate a dynamic discrete choice model of Registered Nurses’ labor supply with random terms. A distinguished feature of our model is that random terms are correlated over time and jobs (habit persistence). Past options and not only the past optimal choices matter for the current choices....

This paper provides a new data set of regional income inequalities within countries based on satellite nighttime light data. We first empirically study the relationship between luminosity data and regional incomes for those countries where regional income data are available. We subsequently use...

Shortage of nurses is a problem in several countries. It is an unsettled question whether increasing wages constitute a viable policy for extracting more labour supply from nurses. In this paper we use a unique matched panel data set of Norwegian nurses covering the period 1993-1998 to estimate...

This paper estimates the effect of innovation on employment at the firm level. Our uniquely long innovation panel data set of German manufacturing firms covers more than 20 years and allows us to use various innovation measures. We can distinguish between product and process innovations as well...

This paper is intended to make a contribution to the empirical literature explaining the rise of unemployment since the 1970s in western economies by means of interactions between shocks and institutions. The contribution is twofold. First, the impact of a general feature of developed economies...

In 2004, a section was added to the German Protection against Dismissal Act, establishing a new procedure to dismiss an employee, given a predetermined severance payment. Most legal scholars presume the change to be without impact, while a minority of experts claims it to be either beneficial or...

There is a lively debate on the persistence of the current banking crisis' impact on GDP. Impulse Response Functions (IRF) estimated by Cerra and Saxena (2008) suggest that the effects of earlier crises were long-lasting. We show that standard estimates of IRFs are highly sensitive to...

This paper analyzes the impact of urbanization on CO2 emissions in developing countries, taking into account the presence of heterogeneity in the sample of countries and testing for the stability of the estimated elasticities over time. The sample covers the period from 1975 through 2003 for...
