While global trade talks have been making very little progress in recent years, the number of preferential trade agreements (PTAs) has grown rapidly, and many of these institutions are reaching much deeper into the domestic political arena than traditional multilateral trade liberalization....

We draw on the policy diffusion literature to shed more light on the determinants of treaty ratification, a crucial step in the formation of international regimes. Our hypotheses stipulate that a country's ratification behaviour is influenced by the ratification choices of other countries in...

This article compares the scientific publication output and international academic visibility of Swiss political science departments, using three indicators (number of publications, number of citations, and the h-index) and publicly available data from two sources: the ISI Web of Knowledge and...

The dominant explanation of public attitudes vis-à-vis economic globalisation focuses on re-distributional implications, with an emphasis on factor endowments and government-sponsored safety nets (the compensation hypothesis). The empirical implication of these theoretical arguments is that in...

Field trials with GM crops are not only plant science experiments. They are also social experiments concerning the implications of government imposed regulatory constraints and public opposition for scientific activity. We assess these implications by estimating additional costs due to...

Existing empirical models of international co-operation emphasize domestic determinants, although virtually all theories of international relations focus on interdependencies between countries. This article examines how much states' linkages with the international system, relative to domestic...

This letter reviews the scientific literature on whether and how environmental changes affect the risk of violent conflict. The available evidence from qualitative case studies indicates that environmental stress can contribute to violent conflict in some specific cases. Results from...

This article reviews the existing theoretical arguments and empirical findings linking renewable and non-renewable natural resources to the onset, intensity, and duration of intrastate as well as interstate armed conflict. Renewable resources are supposedly connected to conflict via scarcity,...

Non-governmental organizations play an increasingly important role in the formation and implementation of environmental policies and institutions. The growing involvement of non-state actors in environmental governance is generally welcomed for two reasons: civil society presumably helps...

Theories explaining government size and its consequences are of two varieties. The first portrays government as a provider of public goods and a corrector of externalities. The second associates larger governments with bureaucratic inefficiency and special-interest-group influence. What...
