Using panel data for a maximum of 109 countries over the years 1976-2000, we empirically analyze the impact of decentralization on the occurrence of transnational terror. Our results show that expenditure decentralization reduces the number of transnational terror events in a country, while...

As is now well documented, aid is given for both political as well as economic reasons. The conventional wisdom is that politically-motivated aid is less effective in promoting developmental objectives. We examine the ex-post performance ratings of World Bank projects and generally find that...

The typical identification strategy in aid effectiveness studies assumes donor motives do not influence the impact of aid on growth. We call this homogeneity assumption into question, first constructing a model in which donor motives matter and then testing the assumption empirically. -- Aid ;...

We analyze the spread of policies dealing with international trafficking in human beings. Arguing that countries are unlikely to make independent choices, we identify pressure, externalities and learning or emulation as plausible diffusion mechanisms for spatial dependence in anti-trafficking...

This paper examines changes in unionization that have occurred over the last decade or so using individual level micro data on twenty seven of the thirty OECD countries, with particular emphasis on Canada, the United Kingdom and the United States. Micro-data is also used to model union...

This paper provides evidence for the existence of a wage curve - a micro-econometric association between the level of pay and the local unemployment rate - in modern U.S. data. Consistent with recent evidence from more than 40 other countries, the wage curve in the United States has a long-run...

This paper analyzes the influence of the shadow economy on corruption and vice versa. We hypothesize that corruption and shadow economy are substitutes in high income countries while they are complements in low income countries. The hypotheses are tested for a cross-section of 120 countries and...

National Time Accounting is a way of measuring society's well-being, based on time use. Its explicit form is the U-index, for "unpleasant" or "undesirable", which measures the proportion of time an individual spends in an unpleasant state. In this paper I review cross-country evidence on...

We focus on the role that the transmission of information between a multilateral (the IMF) and a country has for the optimal design of conditional reforms. Our model predicts that when agency problems are especially severe, and/or IMF information is valuable, a centralized control is indeed...

Using micro-data on six surveys - the Gallup World Poll 2005-2023, the U.S. Behavioral Risk Factor Surveillance System, 1993-2022, Eurobarometer 1991-2022, the UK Covid Social Survey Panel, 2020-2022, the European Social Survey 2002-2020 and the IPSOS Happiness Survey 2018-2023 - we show...
