We consider a model of policy choice in which appropriate policies depend on a country's own circumstances, but the presence of a successful leader generates an informational externality and results in too little 'policy experimentation.' Corrupt governments are reined in while honest...

We estimate the respective contributions of institutions, geography, and trade in determining income levels around the world, using recently developed instruments for institutions and trade. Our results indicate that the quality of institutions trumps' everything else. Once institutions are...

This paper argues that domestic social conflicts are a key to understanding why growth rates lack persistence and why so many countries have experienced a growth collapse after the mid-1970s. It emphasizes conflicts interact with external shocks on the one hand, and the domestic institutions of...

Do countries with lower policy-induced barriers to international trade grow faster, once other relevant country characteristics are controlled for? There exists a large empirical literature providing an affirmative answer to this question. We argue that methodological problems with the empirical...

We distinguish between ideational and interest-based appeals to voters on the supply side of politics, and integrate the Keynes-Hayek perspective on the importance of ideas with the Stigler-Becker approach emphasizing vested interests. In our model, political entrepreneurs discover identity and...

The contemporary approach to political economy is built around vested interests - elites, lobbies, and rent-seeking groups which get their way at the expense of the general public. The role of ideas in shaping those interests is typically ignored or downplayed. Yet each of the three components...

We develop a conceptual framework to highlight the role of ideas as a catalyst for policy and institutional change. We make an explicit distinction between ideas and vested interests and show how they feed into each other. In doing so the paper integrates the Keynes-Hayek perspective on the...

This paper asks why developing country policymakers have been so reluctant to undertake trade reform until the 1980s, and why many of them have embraced open trade policies so wholeheartedly since then. To answer these questions, the paper develops a heuristic index of the "political...

The question addressed in this paper is whether the gap in performance between the developed and developing worlds can continue, and in particular, whether developing nations can sustain the rapid growth they have experienced of late. The good news is that growth in the developing world should...

Large gaps in labor productivity between the traditional and modern parts of the economy are a fundamental reality of developing societies. In this paper, we document these gaps, and emphasize that labor flows from low-productivity activities to high-productivity activities are a key driver of...
