We introduce uncertainty in our general equilibrium model with multi-member groups, following the classical state-space approach of Arrow- Debreu. A host of new interesting economic issues emerge. First, risk averse agents can attempt to insure themselves through markets or through mutual...

We analyze the role of optimal income taxation across different local labor markets. Should labor in large cities be taxed differently than in small cities? We find that a planner who needs to raise revenue and is constrained by free mobility of labor across cities does not choose equal taxes...

Consumption and output responses to fiscal shocks are studied in a model with fiscal foresight. Fiscal foresight reduces both output multipliers and consumption. However, key features such as sticky wages, credit constrained households and elastic labour supply, are able to generate both...

This paper investigates optimized monetary policy rules in the presence of government intervention to stabilize prices of certain categories of goods and services. The paper estimates a small-scale, structural equilibrium model with a sticky-price sector and a subsidized-price sector for a large...

To extend the analysis of continuous-time general-equilibrium macro models we study 2 parameter variants Lp,q of the Lebesgue spaces, thus gaining separate control on the asymptotic behaviour (p) and the local behaviour (q): they behave w.r.t.  p like the spaces ℓp and w.r.t.  q like the...

The equilibrium concept defined by Dubey et al. (DGS, 1990, 2000, 2005) generates equilibria such that asset buyers could raise expected returns by paying more for the assets that they purchase. A simple example shows that, in fact, all equilibria may be return-dominated in that sense....

We prove an equilibrium existence theorem for economies with externalities, general types of non-convexities in the production sector, and infinitely many commodities. The consumption sets, the preferences of the consumers, and the production possibilities are represented by set-valued mappings...

This work proves the existence of an equilibrium for an infinite horizon economy where trade takes place sequentially over time. There exist two types of agents: the first correctly anticipates all future contingent endogenous variables with complete information as in Radner [Radner, R. (1972)....

This is a new formal framework for the theory of competitive equilibrium and its applications.Our "short-run approach" means the calculation of long-run producer optimaand general equilibria from the short-run solutions to the producer's profit maximizationprogramme and its dual. The marginal...
