There is a significant controversy among academics and policy-makers about whether policies matter for economic growth. Recently, Acemoglu et al. (2003) and Easterly (2004) have presented empirical evidence against the commonly held view that policies play an important role in the process of...

The determinants of government responsiveness to its citizens is a key issue in political economy. Here we develop a model based on the solution of political agency problems. Having a more informed and politically active electorate strengthens incentives for governments to be responsive. This...

In this paper we focus on the implications of consumer heterogeneity for whether competition will improve outcomes in health care markets. We show that competition generally favours the majority group as higher quality for the majority is an effective way to increase the quality signal and...

In many economic applications involving comparisons of multivariate distributions, supermodularity of an objective function is a natural property for capturing a preference for greater interdependence. One multivariate distribution dominates another according to the `supermodular stochastic...

This paper is based on presentation given at the June 2011 Conference of the Centre for Growth and Business Cycle Research at the University of Manchester. It reviews key features of the 2007-08 financial crisis, the subsequent 'great recession' and the European public debt problems; in the...

Wealthy individuals often voluntarily provide public goods that the poor also consume. Such philanthropy is perceived as legitimizing one’s wealth. Governments routinely exempt the rich from taxation on grounds of their charitable expenditure. We examine the normative logic of this exemption....

Efficient measures are often not implemented because of their potentially damaging effects on distribution, yet these distributional effects are scarcely studied in economics because of the idea that they are case specific. In this paper we show that when we can separate the effect on efficiency...

We show that direct investments by consumers without the use of financial intermediaries can efficiently allocate financial capital to firms seeking funding for production of a novel consumption good. In our setting, consumers are also investors, and their privately known consumption preferences...
