This note studies a form of a utility function of consumption with habit and leisure that (a) is compatible with long-run balanced growth, (b) hits a steady-state observed target for hours worked and (c) is consistent with micro-econometric evidence for the inter-temporal elasticity of...

We present a model in which banks and other financial intermediaries face both occasionally binding borrowing constraints, and costs of equity issuance. Near the steady state, these intermediaries can raise equity finance at no cost through retained earnings. However, even moderately large...

We examine the performance of forward-looking inflation-forecast-based rules in open economies. In a New Keynesian two-bloc model, a methodology first employed by Batini and Pearlman (2002) is used to obtain analytically the feedback parameters/horizon pairs associated with unique and stable...

We present a model of transnational terrorism where two countries, home and foreign, face a terrorist threat based in the foreign country. The home country chooses how much to invest in defending itself or in reducing terrorist resources either indirectly by subsidising the foreign country or by...

We present a model in which banks and other financial intermediaries face both occasionally binding borrowing constraints, and costs of equity issuance. Near the steady state, these intermediaries can raise equity finance at no cost through retained earnings. However, even moderately large...

Owing to the WTO exemption that allows governments to subsidise arms exports, the arms trade is one of the few remaining areas of trade where we observe lump-sum and per unit transfers to exports. This paper examines the effect of arms controls, in the form of licensing delays, on the incentives...

In this paper, we construct a model of market structure in the global arms industry linking concentration, military procurement, international trade and regional conflict. We show how concentration depends on the willingness of producers to import for their military needs and on the relative...

We examine strategic procurement behaviour by governments and its effect on market structure in sectors, such as defence, where the government is the dominant consumer. In a world economy with trade between producers, and between producers and non-producers, we use a modified Dixit-Stiglitz...
