Finally, the report “Estimating the Constraints to Trade of Developing Countries” sought to identify the most important supply-side constraints to trade expansion and estimate their relative severity for trade and economic growth. The report uses the term “supply-side” constraints by contrast to “market access” constraints and applies it to the categories of economic infrastructure and building productive capacity used in the OECD Creditor Reporting System (Figure 1). The recent food crisis has elicited increased interest. The policy challenge confronting policymakers is to find an effective mix of policies that: (1) promote food production, in particular through productivity growth, (2) foster trade and the proper functioning of markets, and (3) address the wider development dimensions of food insecurity.
