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,...

The effects of defense spending on economic performance and, in particular, on economic growth have been studied extensively in the literature. The empirical findings have been ambiguous so far, partly reflecting the econometric difficulties involved in the estimation of this relationship. The...

Despite many claims by high-ranking policymakers and some scientists that climate change breeds violent conflict, the existing empirical literature has so far not been able to identify a systematic, causal relationship of this kind. This may either reflect de facto absence of such a...

This article studies the consequences of inter-and intrastate wars for economic growth in a large cross-section of countries during the period 1960–89. It establishes that cross-country differences in economic growth are systematically related to the severity and duration of war. The...

This article addresses the wealth-conflict link and discusses it in relation to the dominating `greed vs. grievance' dichotomy. It is further argued...

We engage in a critical assessment of the neo-malthusian claim that climatic changes can be an important source of international tensions, in the extreme even militarized interstate disputes. The most likely scenario is conflict over water allocation in international catchments shared by poorer,...
