We consider a family of exchange economies where consumers have multiprior preferences representing their ambiguity aversion. Under a linear independence assumption, we prove that regular economies are generic. Regular economies exhibit enjoyable properties: odd finite number of equilibrium...

The bond yield dynamics implied by a welfare-maximizing monetary policy and its credibility are explored in general equilibrium. Credibility is captured by a regime change from discretion to commitment. The policy determines the optimal output and inflation responses to a source of inflation...

We welfare rank different types of second-best environmental policy. The focus is on the roles of uncertainty and public finance. The setup is the basic stochastic neoclassical growth model augmented with the assumptions that pollution occurs as a by-product of output produced and environmental...

The 2007-2009 period has been characterised by an oil shock followed by a financial crisis. Higher oil prices and the prospect of higher borrowing costs are likely to reduce the productive potential of OECD economies. The present study provides illustrative numerical estimates of the impact...

We show a simple way to introduce monopolistic competition in a general equilibrium model where prices are fully flexible, the velocity of money is variable and cash-in-advance (CIA) constraints occasionally bind. We establish the conditions under which money has real effects and demonstrate...

We use the HOSV model of trade to find out a link between corruption and the pattern of trade, not just its effect on the volume of trade. We prove that greater corruption in labor-abundant countries will restrict the volume of world trade while corrupt capital-abundant countries promote trade....

The Common Agricultural Policy (CAP) of the European Union has undergone significant reform since the early 1990s, with the aim of improving its market orientation. There is an increasing focus on breaking the link between direct income payments and production decisions — so called...

We evaluate the efficacy of international trade in carbon emission permits when countries are guided strictly by their national self-interest. To do so, we construct a calibrated general equilibrium model that jointly describes the world economy and the strategic incentives that guide the design...

This paper describes the equilibrium of a discrete-time exchange economy in which consumers with arbitrary subjective discount factors and quasi-homothetic period utility functions follow linear Markov consumption and portfolio strategies. Explicit expressions are given for state prices and...
