In this paper we compare three methods for the determination of the reorder point s in an (R; s; Q) inventory model subject to a service level constraint. The three methods di er in the modelling assumptions of the demand process which in turn leads to three di erent approximations for the...

Informationally Robust Equilibria (IRE) are introduced in Robson (1994) as a refinement of Nash equilibria for e.g. bimatrix games, i.e. mixed extensions of two person finite games.Similar to the concept of perfect equilibria, basically the idea is that an IRE is a limit of some sequence of...

We investigate what determines the maturity of loans to small, informationally opaque businesses.We find that longer maturities are associated with collateral pledges, better financial condition, good credit history, and less informational opacity of the borrower.However, we do not find a...

This paper examines how the correlation structure of loan returns within a bank s loan portfolio a.ects its choice of .nancing when the bank faces binding capital constraints and there is asymmetric information about the quality of its loans.The paper uses an asymmetric information model similar...

Numerous researchers have incorporated labor or credit market frictions within simple neoclassical models to (i) facilitate quick departures from the Arrow-Debreu world, thereby opening up the role for institutions, (ii) inject some realism into their models, and (iii) explain cross country...

This paper examines the effect of temporarily suspending the trading of exchange-listed individual stocks.We evaluate whether the regulatory authorities can successfully use the mechanism of trading halts in forcing companies to disclose new and material information to the capital market.In...

We study the structure of markets when traders are given the opportunity to create their own market, as on the internet.On the internet, public exchanges have in many cases been replaced by private exchanges.We use experiments to investigate possible reasons for the failure of public...

A canonical procedure is described, which associates to each infinite information collecting situation a related information collecting situation with finite state and action spaces, in such a way that the two corresponding IC-games are near to each other.Compensations for informants are then...

Why do fundraisers announce initial contributions to their charity?Potential explanations are that these announcements cause future donors to increase their contributions, either because they want to reciprocate the generosity of earlier donors, or because the initial contributions are seen as a...
