Natural resource‐abundant countries constitute both growth losers and growth winners, and the main difference between the success cases and the cases of failure lies in the quality of institutions. With grabber‐friendly institutions more natural resources push aggregate income down, while with producer‐friendly institutions more natural resources increase income. Such a theory finds strong support in data. A key question we also discuss is if resources in addition alter the quality of institutions. When that is the case, countries with bad institutions suffer a double resource curse – as the deterioration of institutions strengthens the negative effect of more natural resources.

Is it possible that excessive reliance on natural resources affects saving and investment in a way that retards economic growth? – and thus, in the long run, the level of output per capita. This paper reviews the literature, explores the data and compares and contrasts the explanatory power and interplay of natural resources and civil liberties, our proxy for institutional variables currently under scrutiny in the literature. We propose that natural resource dependence may be viewed as an exogenous factor that impedes economic growth and investment as well as institutions, even if we stress that natural resource abundance may be good for growth.

This paper examines the political economy of Estonian trade policy in the 1990s. Estonia is a unique case in the world economy, in that the country rapidly implemented unilateral free trade after regaining independence and sustained it right through the 1990s. We analyse the circumstances, interests, ideas and institutions that have shaped Estonian trade policy during the past decade. Our stress is on institutions, particularly the national decision‐making setting for trade policy. Through this prism we try to understand how a free trade regime was implemented and sustained, and what this experience suggests for the feasibility of tree trade elsewhere. We also look at the increasingly ‘multi‐track’ nature of Estonian trade policy through bilateral free trade agreements, WTO accession and, especially, the movement towards EU accession. Although the other trade policy tracks to some extent provide a lockin for unilateral reforms, we argue that EU accession is undermining the simple, classical liberal trade policy regime that existed during the 1990s.

This paper applies modern tools of economic analysis to examine the nature of transnational terrorism and associated collective action concerns that arise in the aftermath of September 11. Throughout the paper, the strategic interaction between rational terrorists and targeted governments are underscored. Networked terrorists draw on their collective strengths to exploit a maximum advantage over targeted governments’ inadequate and uncoordinated responses. A wide range of issues are explored including governments’ deterrence races, undersupplied pre‐emption, and suicidal attacks. Myriad substitutions by terrorists limit government anti‐terrorism policy effectiveness. A host of policy responses are evaluated in light of economic analysis and past econometric evidence.

Combining data on structural characteristics and economic performance for a large sample of Italian firms with data on exporting and importing activity, we uncover evidence supporting recent theories on firm heterogeneity and international trade, together with some new facts. In particular, we find that importing is associated with substantial firm heterogeneity. First, we document that trade is more concentrated than employment and sales, and show that importing is even more concentrated than exporting both within sectors and along the sector‐ and country‐extensive margins. Second, while supporting the fact that firms involved in both are the best performers, we also find that firms involved only in importing activities perform better than those involved only in exporting. Our evidence suggests there is a strong self‐selection effect in the case of importers and the performance premia of internationalised firms correlate relatively more with the degree of geographical and sectoral diversification of imports.

While the role of exports in promoting growth in general, and productivity in particular, has been investigated empirically using aggregate data for countries and industries for a long time, only recently have comprehensive longitudinal data at the firm level been used to look at the extent and causes of productivity differentials between exporters and their counterparts which sell on the domestic market only. This paper surveys the empirical strategies applied, and the results produced, in 54 microeconometric studies with data from 34 countries that were published between 1995 and 2006. Details aside, exporters are found to be more productive than non‐exporters, and the more productive firms self‐select into export markets, while exporting does not necessarily improve productivity.

Is a firm's ability to export an important determinant of environmental performance? To answer this question, we construct a unique microdata set that merged two rich manufacturing firm‐level data sets for China for 2007. When combining this new data set with well‐received empirical specifications, we found that both export status and export intensity are associated with lower sulphur dioxide (SO₂) emissions intensity. In addition to the traditional OLS estimation, we verified this association by using the propensity score matching method. Our findings show that the baseline result still holds. In short, exporters are more environmentally friendly than nonexporters, which is in line with previous evidence reported for developed economies. We further discuss potential mechanisms that explain the observed pattern and show that exporters realise higher abatement efforts compared to nonexporters. This study complements the literature in terms of providing China's microevidence on SO₂ abatement efforts. It also serves as a first step towards a better understanding of the impact of trade on the environment, especially in developing countries.
