The World Trade Organisation's Doha Cotton Initiative: A Tale of Two Issues

Four West African nations have demanded that the WTO's Doha Development Agenda include a Cotton Initiative that involves two issues: cutting cotton subsidies and tariffs, and assisting farm productivity growth in Africa. This paper provides estimates of the potential economic impacts of (a) complete or partial removal of cotton subsidies and import tariffs globally and (b) cotton productivity growth through the adoption of genetically modified (GM) cotton varieties. Use is made of the GTAP database and global economic model to address both these issues. On Doha, our results confirm that for cotton – unlike for other agricultural subsidies and tariffs – it is subsidy reductions rather than tariff cuts that would make by far the largest impact. For Sub‐Saharan Africa the potential gains are huge relative to the effects on that region of reforming other merchandise trade policies. And they could be more than doubled if that reform provided the cash for farmers to take advantage of the biotechnology revolution and adopt GM cotton varieties. But those potential gains, and the affordability of switching to costly GM seed, depend crucially on the extent to which high‐income countries are willing to lower domestic support to their cotton farmers.     

Intra-industry trade in the European computers industry

Intra-Industry Trade in the European Computers Industry. —This paper analyzes the pattern of intra-industry trade in the European computers industry. Hypotheses regarding both country-specific and industry-specific factors are tested. Those include proxies for level of economic development, market size, market proximity, scale economies and market concentration. The problem of categorical aggregation is explicitly addressed and a method to overcome is suggested. The results of the econometric analysis corroborate the predictions of the theoretical models and their ability to identify at least some of the crucial factors driving to international specialization.     

Multidimensional inequality with variable population size

Summary. We study inequality in a context of more than one variable by extending a celebrated result of Hardy, Littlewood and Pölya (1934) to the case of distributions with variable population sizes, whose individuals differ in many characteristics besides income. A new ordering between rectangular matrices, representing such distributions, is provided and characterized by convexity theory.Received: 19 October 2003, Revised: 7 September 2004, JEL Classification Numbers: D31, D63, I31.I am indebted to C. d’Aspremont, V. Dardanoni, G. Koshevoy, K. Mosler and especially J. Weymark and an anonymous referee for many useful comments.     

Tariff change,foreign capital and immiserization: A theoretical analysis

This paper analyzes the possibility that tariff reductions in the presence of foreign capital may be immiserizing. Other impacts of tariff revisions in a Latin America-like context are also discussed.     

Revisiting strategic versus non-strategic cooperation

We propose a novel experimental method that disentangles strategically- and non-strategically-motivated behavior. We apply it to an indefinitely-repeated prisoner’s dilemma game to observe simultaneously how the same individual behaves in situations with future interaction and in situations with no future interaction, while controlling for expectations. This method allows us to determine the extent to which strategically-cooperating individuals are responsible for the observed pattern of cooperation in experiments with repeated interaction, including the so-called endgame effect. Our results indicate that the most common motive for cooperation in repeated games is strategic.     

Regulatory Capture: A Review

This article reviews both the theoretical and empirical literatureson regulatory capture. The scope is broad, but utility regulationis emphasized. I begin by describing the Stigler–Peltzmanapproach to the economics of regulation. I then open the blackbox of influence and regulatory discretion using a three-tierhierarchical agency model under asymmetric information (in thespirit of Laffont and Tirole, 1993). I discuss alternative modellingapproaches with a view to a richer set of positive predictions,including models of common agency, revolving doors, informationallobbying, coercive pressure, and influence over committees.I discuss empirical work involving capture and regulatory outcomes.I also review evidence on the revolving-door phenomenon andon the impact that different methods for selecting regulatorsappear to have on regulatory outcomes. The last section containsopen questions for future research. Footnotes ¹ E-mail address: dalbo{at}haas.berkeley.edu     

Longitudinal analysis of entrepreneurship and competitiveness dynamics in Latin America

This study analyzes the relationship between entrepreneurial dynamics in Latin-American countries and the level of competitiveness these countries show. Based on the research conducted by Wennekers et al. [Small Business Economics, 24(3):293–309, 2005] that demonstrates a U-shaped relationship between the country’s rate of entrepreneurship and its level of competitiveness and economic development, we hypothesize that Latin-American countries have a descending behaviour under the U-shaped curve approach. The results from three regression models support this hypothesis and suggest that competitiveness and economic growth deter entrepreneurial dynamics on Latin-American countries. We discuss that Latin-American countries need to improve some structural factors to achieve a high level of entrepreneurial dynamics.

Is the cardholder an efficient alarm system to detect credit card incidents?

There is a growing tendency in credit card industry to increase the contribution of the smallest players, the cardholders, in the detection of card incidents. This article examines whether cardholders are efficient at detecting/communicating incidents of theft, loss or fraudulent use of their cards. The analysis focuses on whether they demonstrate enough speed of response to support a risk control subsystem by the issuer. The research follows a completely new approach showing how the issue can be handled by applying the concept of elasticity, a notion just recently exported from economics to the field of statistics by linking it with the reverse hazard rate. The issue is focused on the analysis of the characteristics of the elasticity function of the random variable that measures the delay of cardholders in reporting incidents. This study is illustrated with an application to a real data set of 1069 incidents.
