The main aim of this paper is to assess whether there is a statistically significant environmental impact of cities within European countries. Second, starting from the estimated environmental impact of cities within European countries, the paper investigates whether cross-country variation can...

We examine immigrant entrepreneurship and the survival and growth of immigrant-founded businesses over time relative to native-founded companies. Our work quantifies immigrant contributions to new firm creation in a wide variety of fields and using multiple definitions. While significant...

In this paper, we estimate the potential tax burden in a panel data set comprising OECD countries over the period 2000-2021. To this end, we use non-parametric and parametric techniques: Data Envelopment Analysis (DEA) and Stochastic Frontier Analysis (SFA). In this way, it will be possible for...

This paper provides a critical review of models of the spread of the coronavirus (SARS-CoV-2) that have been influential in recent policy discussions. It notes potentially important features of the real- world environment that the standard models do not incorporate and discusses reasons why...

We estimate Okun's law, the negative relationship between output and the unemployment rate, at the sector level for the US, the UK, Japan, and Switzerland to test several hypotheses that may explain why the aggregate Okun's coeffcients are different across countries. Specifically, we show that...

In this paper, we compare the total size of intertemporal public liabilities (IPLs) of several European countries and the United States. We utilize the machinery of generational accounting in order to calculate the composition of the countries IPLs, that is the sum of the explicit and implicit...
