We use the PISA student-level achievement database to estimate international education production functions. Student characteristics, family backgrounds, home inputs, resources, teachers and institutions are all significantly related to math, science and reading achievement. Our models account...

Labor market performance has differed considerably between OECD countries over the last two decades. The focus of the literature so far has been to ask whether these differences can be explained by varying degrees of labor market rigidities and generosity of welfare states. This paper takes a...

We propose an explanation of why Europeans choose to work fewer hours than Americans and also suffer higher rates of unemployment. Labor market regulations, unemployment benefits, and high levels of public consumption in many European countries reduce, ceteris paribus, the gains from being...

Previous findings of long-run purchasing power parity come mainly from data for industrial countries, raising the issue of whether the results suffer sample-selection bias and exaggerate the general relevance of parity reversion. This study uncovers substantial cross-country heterogeneity in the...

This paper evaluates whether the level of public corruption influences COVID-19 case fatality rates. Using cross-section data, including 64 countries and multiple regression techniques, we find that the level of corruption is positively and significantly associated with COVID-19 human costs....

We exploit two unusual policy features of academic high schools in Seoul, South Korea - random assignment of pupils to high schools within districts and conversion of some existing single-sex schools to the coeducational (coed) type over time - to identify three distinct causal parameters: the...

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...

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...
