In thinking about policy, academic economists alternate between theoretical models in which governments can design finely-tuned optimal interventions and practical considerations which usually assume the government to be incompetent and hostage to special interests. I argue in this paper that...

Reducing tariffs and increasing consumption taxes is a standard IMF advice to countries that want to open up their economy without hurting government finances. Indeed, theoretical analysis of such a tariff-tax reform shows an unambiguous increase in welfare and government revenues. The present...

A study of distortions to agricultural incentives in 18 developing countries during 1960-84, by Krueger, Schiff and Valdés (1988; 1991), found that policies in most of those developing countries were directly or indirectly harming their farmers. Since the mid-1980s there has been a substantial...

What shapes the optimal degree of progressivity of the tax and transfer system? On the one hand, a progressive tax system can counteract inequality in initial conditions and substitute for imperfect private insurance against idiosyncratic earnings risk. At the same time, progressivity reduces...

Even relatively poor people oppose high rates of redistribution because of the anticipation that they, or their children, may move up the income ladder. This ‘Prospect of Upward Mobility’ (POUM) hypothesis is commonly advanced to explain why democracies do not engage in large-scale...

The impact of protection on economic growth is one of the traditional issues in economic history, which has enjoyed a revival in recent times, with the publication of a number of comparative quantitative papers. They all share a common weakness: they measure protection with the ratio of custom...

The objective of this paper is to estimate the potential pro-poor bias in the existing structure of protection in six countries in Sub-Saharan Africa (SSA) (i.e., whether it redistributes income from rich to poor households). We also explore the extent to which the barriers faced by SSA...

This paper empirically explores the political-economic determinants of why governments choose to tax or subsidize trade in agriculture. We use a new data set on nominal rates of assistance (NRA) across a number of commodities spanning the last four decades for 64 countries. NRAs measure the...

Social policies are likely to have an ever-more prominent role in trade policy discussions in the years ahead for the new World Trade Organization (WTO). Many developing countries perceive the entwining of these social issues with trade policy as a threat to both their sovereignty and their...

The paper sees countertrade - the tying of trade flows - as an insurance contract that mitigates contractual hazards and reduces the incentive for ex post `hold-up' when parties are `locked' in a relationship after they have made specific investment. This way tying is seen as a commitment device...
