We study the efficiency of capital allocations at state-controlled and privately owned business groups in China. Using highly granular data on within-group capital transfers, we document stark differences: while private groups allocate more capital to units with better investment opportunities,...

In recent years, comparative economics experienced a revival, with a new focus on comparing capitalist economies. The theme of the new research is that institutions exert a profound influence on economic development. We argue that, to understand capitalist institutions, one needs to understand...

When asked to name one proposition in the social sciences that is both true and non-trivial, Paul Samuelson famously replied: 'Ricardo's theory of comparative advantage'. Truth, however, in Samuelson's reply refers to the fact that Ricardo's theory of comparative advantage is mathematically...

I survey the advice given by the fifty most popular personal finance books and compare it to the prescriptions of normative academic economic models. Popular advice frequently departs from normative principles derived from economic theory, which should motivate new hypotheses about why...

European countries are much more generous to the poor relative to the US level of generosity. Economic models suggest that redistribution is a function of the variance and skewness of the pre-tax income distribution, the volatility of income (perhaps because of trade shocks), the social costs of...

Different beliefs about how fair social competition is and what determines income inequality, influence the redistributive policy chosen democratically in a society. But the composition of income in the first place depends on equilibrium tax policies. If a society believes that individual effort...

Intertemporal conflicts occur when a group of agents with heterogeneous time preferences must make a collective decision about how to manage a common asset. How should this be done? We examine two methods: an 'Economics' approach that seeks to implement efficient allocations, and a 'Politics'...

We study how political factors shape competition in the mobile telecommunication sector. We show that the way a government designs the rules of the game has an impact on concentration, competition, and prices. Pro-competition regulation reduces prices, but does not hurt quality of services or...

A number of studies - including our own - find a mid-life dip in well-being. We review a psychology literature that claims that the evidence of a U-shape is "overblown" and if there is such a decline it is "trivial". We find remarkably strong and consistent evidence across countries and US...

This study uses data from Academic Analytics to examine gender differences in promotion to associate professor in economics. We found that women in economics were 15% less likely to be promoted to associate professor after controlling for cumulative publications, citations, grants and grant...
