This paper demonstrates that the dynamics of a rational learning process with private information differ substantially from those without such information. As has been shown by Jund and Vives (1996), the existence of private information has no effect upon the convergence of the learning process...

We study the relationship between default and the maturity structure of the debt portfolio of a Sovereign, under uncertainty. The Sovereign faces a trade-off between a future costly default and a high current fiscal effort. This results into a debt crisis in case a large initial issuance of long...

We study a model where investment decisions are based on investors’ information about the unknown and endogenous return of the investment. The information of investors consists of endogenously determined messages sold by financial analysts who have access to both public and private information...

In this paper, we consider two polar dynamical models in which firms use debt (loans) to finance their investment expenditure: a three-dimensional supply-driven model and a sophisticated 20-D Keynesian growth model. In the first, firms' debt accumulations interact with the income distribution...

In this paper, we use the Wang and Zender (98) model of auctions, and derive, using optimal control, the optimal bidding strategy in the Spanish Treasury Bill auctions (STBA). Spain is the only country that uses a hybrid system of discriminatory and uniform price auctions: winning bidders pay...

This paper investigates the accuracy of the log-linear approximation method in welfare calculations, especially in measuring welfare gains of international risk sharing. We derive closed-form solutions for a two-country complete market economy using log-linearization and a nonlinear solution...

This paper examines the pattern of consumption and savings when heterogeneous agents enter into marriage and have the option of dissolving the marriage if there exists no set of consumption allocations that can preserve the union. The research presents an analysis of this scenario using dynamic...

For years, the problems associated with the Lucas critique have loomed over empirical macroeconomics. However, relatively little effort has been devoted to testing the empirical importance of this critique. This paper develops a set of tests for small macroeconometric models, especially those...
