Bewley's condition on production sets, imposed to ensure the existence of an equilibrium price density when L? is the commodity space, is weakened to allow applications to continuous-time problems, and especially to peak-load pricing when the users' utility and production function are Mackey...

We provide an equilibrium multi-asset pricing model with micro-founded systemic risk and heterogeneous investors. Systemic risk arises due to excessive leverage and risk taking induced by free-riding externalities. Global risk-sensitive financial regulations are introduced with a view of...

It is often argued that asset prices exhibit patterns incompatible with the behaviour of rational, optimizing agents. This paper proposes a rational framework which generates asset prices which appear irrational. This is accomplished by studying rational expectations equilibria in the presence...

The implications of Value-at-Risk regulations are analyzed in a CARA-normal general equilibrium model. Financial institutions are heterogeneous in risk preferences, wealth and the degree of supervision. Regulatory risk constraints lower the probability of one form of a systemic crisis, at the...

We consider an exchange economy with time-inconsistent consumers whose preferences are additively separable. When these consumers trade in a sequence of markets, their time-inconsistency may introduce a non-convexity that gives them an incentive to trade lotteries. If there are many consumers,...

This paper uses a small open economy model to address two outstanding issues in monetary policy: (1) what restrictions on the policy rule ensure that the central bank does not introduce real indeterminacy into the economy, and (2) what is the optimal long run rate of inflation. The small open...

Becker (1974) introduced to modern economics the idea that others care about what others think about them and derived many useful insights from this assumption. But he did not provide a very complete description of the general equilibrium of an economy in which people both demand respect from...

With L∞ as the commodity space, the equilibrium price density is shown to be a continuous function of the commodity characteristics. The result is based on symmetry ideas from the Hardy-Littlewood-Pólya theory of rearrangements; and it includes, but is not limited to, the case of symmetric...

We give variants on Berge's Maximum Theorem in which the lower and the upper semicontinuities of the preference relation are assumed for two different topologies on the action set, i.e., the set of actions availabe a priori to the decision-maker (e.g. a household with its consumption set). Two...
