We assess the impact of geopolitical risk and world uncertainty on the sovereign debt risk of 26 European Economies during the period 1984-2022, through the implementation of OLS-Fixed Effects regressions and the Generalized Method of Moments (GMM). We find that geopolitical tensions and global...

To date, only annual information on economic activity is published for the 16 German states. In this paper, we calculate quarterly regional GDP estimates for the period between 1995 to 2021, thereby improving the regional database for Germany. The new data set will regularly be updated when...

The paper sets up a two-region endogenous growth model to discuss growth and regional convergence of unified Germany. It emphasises the role of private and public capital accumulati on during the developing process. The theoretical part derives fiscal policy rules which establish convergence of...

After 162 years of political unification, Italy still displays large regional economic differences. In 2019, the per capita GDP of Lombardia was 39,700 euros, but Calabria's per capita GDP was only 17,300 euros. We build a two-region, two-sector model of the Italian economy to measure the wedges...

The COVID-19 crisis poses new policy challenges and has spurred new research agendas in public economics. In this article, we selectively reflect on how the field of public economics has been shaped by the COVID-19 pandemic and discuss several areas where more research is necessary. We highlight...

Employers in an online labor market often pursue workers with little capacity to take on more work. The pursuit of low-capacity workers is consequential, as these workers are more likely to reject employer inquires, causing a reduction in the probability a job opening is ultimately filled. In an...

Information asymmetries can prevent markets from operating efficiently. An important example is the labor market, where employers face uncertainty about the productivity of job candidates. We examine theoretically and with laboratory experiments three key questions related to hiring via...

This paper studies equilibrium unemployment in a two-region economy with matching frictions, where workers and jobs are free to move and wages are bargained over. Job-seekers choose between searching locally or searching in both regions. Search-matching externalities are amplified by the latter...

We analyse how spatial disparities in innovation activities, coupled with migration costs, affect economic geography, growth and regional inequality. We provide conditions for existence and uniqueness of a spatial equilibrium, and for the endogenous emergence of industry clusters. Spatial...

We consider an economic geography setting in which firms are free to choose one of the following organizational types: (i) integrated firms, which perform all their activities at the same location, (ii) horizontal firms, which operate several plants producing the same good at different...
