It is well known that, under uniform impatience, positive net supply assets are free of bubbles for non-arbitrage kernel deflators that yield finite present values of wealth. However, this does not mean that prices cannot be above the series of deflated dividends for the deflators given by the...

Individuals exchange contracts for the delivery of commodities in competitive markets and, simultaneously, act strategically; actions affect utilities across individuals directly or through the payoffs of contracts. This encompasses economies with asymmetric information, Nash-Walras equilibria...

We investigate sunspot equilibria in a static, one-commodity model with taxes and transfers denominated in money units. Volatility in this economy is purely monetary, since the only uncertainty is about the price level. We construct simple, robust examples of sunspot equilibria that are not mere...

We consider a Lucas asset-pricing model with heterogeneous agents, exogenous labor income, and a finite number of exogenous shocks. Although agents are infinitely lived, endowments and dividends are time-invariant functions of the exogenous shock alone and are thus restricted to lie in a...

The endogeneity of preferences implies that not only individual preferences -along with technologies, government policies, and the organization of society and markets- determine economic outcomes, but also that the economic, social, legal, and cultural structure of society affects preferences....

Consider a two period financial economy with incomplete markets and with agents having von Neumann-Morgenstern utility functions. It is well known that when the economy’s endowments are collinear, its excess demand function will obey the weak axiom when certain mild restrictions are...

These lecture notes are about financial innovations. We ask why are there some innovation and how is an innovative idea realized. This forces us to consider practical and structural aspects (regulations, taxation, markets) as key drivers of innovations and also basic formal aspects in valuation....

The aim of this paper is to prove that if the consumption set of an economy with incomplete financial markets is semi-algebraic, then the corresponding pseudo-equilibrium manifold is also semi-algebraic. For this, we proceed by constructing an incomplete financial economy with real assets and...

We address a dynamic general equilibrium model where securities are backed by collateralized loans, and borrowers face endogenous liquidity contractions and financial participation constraints. Although the only payment enforcement is the seizure of collateral guarantees, restrictions on credit...

This paper presents a stochastic dynamic general equilibrium model calibrated for Venezuela that incorporates inter-sectorial relationships. With this model it is possible to assess the impact on the aggregate economic activity generated by productivity shocks or demand shocks to a specific...
