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...

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 ;...

There is no significant relationship between the improvement in happiness and the long term rate of growth of GDP per capita. This is true for three groups of countries analyzed separately - 17 developed, 9 developing, and 11 transition - and also for the 37 countries taken together. Time series...

To what extent are improvements in quality of life (material living levels, health, education, political and civil rights, happiness, and the like) associated with economic growth? International comparisons of quality of life (QoL) conditions almost always point to a strong positive association...

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...

Although cross section relationships are often taken to indicate causation, and especially the important impact of economic growth on many social phenomena, they may, in fact, merely reflect historical experience, that is, similar leader-follower country patterns for variables that are causally...

Long term trends in happiness and income are not related; short term fluctuations in happiness and income are positively associated. Evidence for this is found in time series data for developed countries, transition countries, and less developed countries, whether analyzed separately or pooled....

If society's goal is to increase people's feelings of well-being, economic growth in itself will not do the job. Full employment and a generous and comprehensive social safety net do increase happiness. Such policies are arguably affordable not only in higher income nations but also in countries...

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...

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...
