We investigate the occurrence of bubble-crash pricing patterns in laboratory financial markets with a mixture of experienced and inexperienced traders. We find that even with a minority of experienced traders, bubbles are substantially abated.

We show experimentally that whether and how communication achieves beneficial social outcomes in a hidden-information context depends crucially on whether low-talent agents can participate in a Pareto-improving outcome. Communication is effective (and patterns of lies and truth quite systematic)...

This paper studies the effect of additional government revenues on political corruption and on the quality of politicians, both with theory and data. The theory is based on a political agency model with career concerns and endogenous entry of candidates. The data refer to Brazil, where federal...

The importance of seigniorage relative to other sources of government revenue differs markedly across countries. This paper tries to explain this regularity by studying a political model of tax reform. The model implies that countries with a more unstable and polarized political system will have...

We investigate the effect of electoral rules and forms of government on fiscal policy outcomes in a large sample of democracies. We rely on different estimation methods to address prospective problems of statistical inference, due to nonrandom selection of these constitutional rules. The...

This paper analyzes a model in which a group of rational individuals votes over the composition and time profile of public spending. All voters agree that a balanced budget is ex ante optimal. However, if there is disagreement between current and future majorities, a balanced budget is not a...
