This paper provides an explanation for why political leaders may want to adopt ideological positions and maintain them over time even in the face of conflicting evidence. We study a dynamic framework in which politicians are better informed than the voting public about an underlying state of...

Fiscal reform is central to the process of transforming a Soviet-type economy to a market economy, for with the emergence of a significant private sector, the boundaries between the public and private sectors needs to be more sharply drawn. The paper draws lessons from the experience of the...

This paper assesses the impact of adopting a post-grant review institution in the US patent system by comparing the “opposition careers” of European Patent Office (EPO) equivalents of litigated US patents to those of a control group of EPO patents. We demonstrate several novel methods of...

The paper combines insights from the recent research programs on constitutions and economic policy, and on history, institutions and growth. Drawing on cross-sectional as well as panel data, it presents new empirical results showing that the form of democracy (rather than democracy vs....

This paper contains a selective review of some of the key fiscal issues faced by transition economies. The twelve countries that provide the empirical background for this study have all been under Fund programmes for at least some of the time since they initiated their transitions from plan to...

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...

Conventional wisdom in economic history suggests that conflict between countries can be enormously disruptive of economic activity, especially international trade. Yet nothing is known empirically about these effects in large samples. We study the effects of war on bilateral trade for almost all...

Leaders compensate supporters not just for performing their duties but also in order to preempt an overthrow by the same supporters. We show how succession rules affect the power of leaders relative to supporters as well as the resources expended on possible succession struggles. We compare two...

Theory and empirics are ambiguous on the effect of democracy on growth. Cross-country studies find that democracy has no significant impact on growth. In contrast, within-country studies find a strong positive effect of transition to democracy. We reconcile this inconsistency by showing that the...

We develop a theory of interstate conflict in which the degree of genealogical relatedness between populations has a positive effect on their conflict propensities because more closely related populations, on average, tend to interact more and develop more disputes over sets of common issues. We...
