Nuclear‐and missile‐related trade and developments for selected countries,November 1997‐February 1998

The material in this overview is drawn from selected abstracts that appear in the Center for Nonproliferation Studies' nuclear and missile databases. Transactions of nuclear and missile technologies, parts, and materials are listed according to the recipient country. Other developments are listed according to the country where the event or development took place.     

A non‐linear defence‐growth nexus? evidence from the US economy

The defense‐growth nexus is investigated empirically using time series data for the US and allowing the effect of defense spending on growth to be non‐linear. Using recently developed econometric methods involving threshold regressions, evidence of a level‐dependent effect of military expenditure on GDP growth is found: the positive externality effect of defense spending prevails for relatively lower levels of defense spending (with respect to the history of defense spending in the US) and reverts its influence for higher levels.     

BUTTER,GUNS AND ICE‐CREAM THEORY AND EVIDENCE FROM SUB‐SAHARAN AFRICA

This paper is intended to complement the existing literature on civil wars. First, it presents a simple theoretical model of conflict that defines a two‐sector economy. In a contested sector, two agents struggle to appropriate the maximum possible fraction of a contestable output. In an uncontested sector, they hold secure property rights over the production of some goods. Agents split their resource endowment between ‘butter’, ‘guns’ and ‘ice‐cream’. Following the theoretical insights the empirical analysis focuses on the relationship between civil wars and different sectors of the economy. In particular, a panel probit specification shows that the incidence of a civil war decreases in the size of manufacturing sector.     

INTRA‐GROUP COMPETITION AND INTER‐GROUP CONFLICT: AN APPLICATION TO NORTHERN IRELAND

This paper reviews four economic theories of leadership selection in conflict settings. The ‘credibility rationale’, argues that hawks may actually be necessary to initiate peace agreements. The ‘bargaining rationale’ predicts that while doves are more likely to secure peace, post‐conflict hawks may be rationally selected. The ‘social psychological rationale’ captures the idea of a competition over which group can form the strongest identity. Dove selection can be predicted during conflict, but hawk selection post‐conflict. Finally, the ‘expressive rationale’ predicts that regardless of the underlying nature of the game the large group nature of decision‐making in rendering individual decision makers non‐decisive in determining the outcome of elections may cause them to make choices based primarily on emotions. Finally, the paper analyses the extent to which the theories can throw light on Northern Ireland electoral history over the last 25 years.     

Technical and proliferation‐related aspects of the dismantlement of Russian Alfa‐Class nuclear submarines

When does a state become a “nuclear weapon state”? How we choose to answer this question has significant implications for proliferation assessment, analysis, and policy. Traditionally, the standard demarcation line has been a state's first nuclear test, but in recent years analysts have increasingly focused instead on the accumulation of a significant quantity (SQ) of fissile material. The article argues that although the test/no-test indicator clearly has problems, its replacement by the SQ/no-SQ indicator would be highly counterproductive. The article instead proposes supplementing the traditional test/no-test indicator with a theory-driven approach that focuses on the incentives and disincentives to test.
