Lengwiler, Yvan; Wolfstetter, Elmar - 2000

In many auctions, the auctioneer is an agent of the seller. This delegation invites corruption. In this paper we … propose a model of corruption, examine how corruption affects the auction game, how the anticipation of corruption affects … that may prevent corruption, and compare them to the fee schedules employed by major auction houses. -- auctions …

Quantile hedging

Föllmer, Hans; Leukert, Peter - 1998

In a complete financial market every contingent claim can be hedged perfectly. In an incomplete market it is possible to stay on the safe side by superhedging. But such strategies may require a large amount of initial capital. Here we study the question what an investor can do who is unwilling...

On model based seasonal adjustment procedures

Breitung, Jörg - 1998

In this note the unobserved component approach underlying the software package SEATS is compared with the Beveridge-Nelson type of decomposition for seasonal time series. The main strength of the SEATS approach lies in the appealing model formulation and the careful specification and adjustment...

The monetary model of the exchange rate : a structural interpretation

Moersch, Mathias; Nautz, Dieter - 1998

We emphasize the importance of properly identifying the long-run relations underlying the monetary model of the exchange rate. The separate estimation of long-run money demands leads to a "structural" error correction equation which allows an interpretation of the various channels affecting the...

Sequential versus independent commitment : an indirect evolutionary analysis of bargaining rules

Güth, Werner - 1998 - Rev.

Rational bargaining behavior depends crucially on the rules of bargaining, especially on whether parties decide sequentially or independently. Whereas in ultimatum bargaining the proposer can exploit the responder, independent commitments result in more balanced payoffs. To limit the scope of...

Smooth discrimination analysis

Mammen, Enno; Cybakov, Aleksandr B. - 1998

Discriminant analysis for two data sets in IRd with probability densities f and g can be based on the estimation of the set G = {x : f(x) ≥ g(x)}. We consider applications where it is appropriate to assume that the region G has a smooth boundary. In particular, this assumption makes sense if...

Local risk-minimization under transaction costs

Lamberton, Damien; Pham, Huyên; Schweizer, Martin - 1998

We propose a new approach to the pricing and hedging of contingent claims under transaction costs in a general incomplete market in discrete time. Under the assumptions of a bounded mean-variance tradeoff, substantial risk and a nondegeneracy condition on the conditional variances of asset...

Additional logarithmic utility of an insider

Amendinger, Jürgen; Imkeller, Peter; Schweizer, Martin - 1998

In this paper, we consider a security market in which two investors on different information levels maximize their expected logarithmic utility from terminal wealth. While the ordinary investor's portfolio decisions are based on a public information flow, the insider possesses from the beginning...

A note on stochastic volatility, GARCH models, and hyperbolic distributions

Jaschke, Stefan R. - 1997

We establish a relation between stochastic volatility models and the class of generalized hyperbolic distributions. These distributions have been found to fit exceptionally well to the empirical distribution of stock returns. We review the background of hyperbolic distributions and prove...

Nonparametric factor analysis of time series

Rodríguez Poo, Juan Manuel; Linton, Oliver - 1998

We introduce a nonparametric smoothing procedure for nonparametric factor analaysis of multivariate time series. The asymptotic properties of the proposed procedures are derived. We present an application based on the residuals from the Fair macromodel. -- Factor Analysis ; Time Series ; Kernel...
