We present an overview of models of long-term self-enforcing labour contracts in which risk sharing is the dominant motive for contractual solutions. A base model is developed which is sufficiently general to encompass the two-agent problem central to most of the literature, including variable...

This paper argues that existing empirical models of interest rate rules are too simplistic. The hybrid Phillips curve implies that policymakers should respond to both current and expected future inflation rates, in contrast to existing models. We provide evidence that UK policymakers do this.

The Opportunistic Approach to Monetary Policy is an influential but untested model of optimal monetary policy. We provide the first tests of the model, using US data from 1983Q1-2004Q1. Our results support the Opportunistic Approach. We find that policymakers respond to the gap between inflation...

It is shown in the context of a new economic geography that, when capital is heterogeneous (a degree of environmental sensitivity), then trade liberalization may lead to industrial agglomeration and inter-regional trade. Capital heterogeneity gives local monopsony power to firms but also...

This paper analyzes how the determinants of two entrepreneurs’ choice whether to conduct product innovation R&D projects alone, or in a cross license agreement, or in a research joint venture depend on the intrinsic nature of the R&D projects. Results show that in fundamental research -- which...

We show in the context of a bilateral oligopoly where all agents are allowed to behave strategically the unexpected result that when the number of buyers becomes large the outcomes in a strategic market game do not converge to those at the Cournot equilibrium. However, convergence to Cournot...

This paper analyses the signal uncertainty implicit in the communications of the Bank of England's Monetary Policy Committee (MPC). Unlike previous studies, which seek to construct a qualitative uncertainty index that heavily relies on subjective interpretations of key expressions, we limit...

We investigate the question of whether sophistication in risk management fosters banking stability. We compare a simple banking system in which an average rating is used with a sophisticated banking system in which banks are able to assess the default risk of entrepreneurs individually. Both...

This paper analyses horizontal and vertical price dynamics in the EU petroleum markets. The results indicate that the cross-country price differentials have significant impact on the local price adjustments. The uncovered patterns can be seen as the first empirical support for the...

This paper considers a simple stochastic model of international trade with three countries. Two of the tree countries are in an economic union. Comparisons are made between equilibrium welfare for these two countries under fixed and flexible exchange rate regimes. Within the model it is shown...
