The dynamic price competition in a horizontally differentiated duopoly when consumers value previous market shares is analyzed. The conditions for the existence of stable Markov-Perfect Equilibrium(MPE) in linear strategies are established. When they exist, the optimal pricing policies suggest...

Financial crises are endogenized through institutions related to the corporate sector and the interbank market. Financial crises can emanate from financial institutions which determines the nature of equilibrium in the interbank market. In a pooling equilibrium all illiquid banks are treated in...

By using asymptotic expansion techniques approximation formulae are developed for the bias of ordinary and generalized Least Squares Dummy Variable (LSDV) estimators in dynamic panel data models. Earlier results on bias approximation in first-order stable dynamic panel data models are extended...

We develop a theoretical model that replicates three observed phenomena in securities markets: serial correlation in trades; serial correlation in squared price changes (conditional heteroskedasticity); and more persistent serial correlation in trades than in squared price changes. In the model...

This paper investigates under which conditions we can find a policy that can be made time-consistent in an economy with both private and public capital, and how far in terms of growth and welfare this policy would be with respect to the full-commitment policy. A benevolent government chooses...

We provide a proof of the consistency and asymptotic normality of the estimator suggested by Heckman (1990) for the intercept of a semiparametrically estimated sample selection model. The estimator is based on "identification at infinity" which leads to non-standard convergence rate. Andrews and...

We consider a multi-stage game of fund-raising to study the announcement strategy of a fund-raiser, who is privately informed about the number of potential contributors, with the objective of collecting maximal contributions for a public project. We show that whether the public project is convex...

The proportional value is the unique strictly consistent TU and NTU value which, in two-player TU games, gives players equal proportional gains from cooperation. Strict consistency means consistency with respect to the Hart and Mas-Colell (1989) reduced game. The proportional value is a...

We approach the problem of preference aggregation by endowing both individuals and coalitions with partially-ordered or incomplete cardinal preferences. Consistency across preferences for coalitions comes in the form of the Extended Pareto Rule: if two disjoint coalitions A and B prefer x to y,...

It is commonly argued that exchange rate risk depresses international trade. However, the large literature on this subject has not yet provided conclusive evidence. This paper analyzes why it is so difficult to obtain a clear answer from time series analyses. We use data on bilateral aggregate...
