Im Mittelpunkt der gerade auch von solchen "atypischen Unternehmen" nach wie vor geäußerten Ängste stehen die durch das Basler Gremium geforderten Ratingsysteme, wobei Beobachter der Diskussion den Eindruck gewinnen können, als wäre das Rating von Kreditnehmern etwas völlig Neuartiges....

The trading of securities on multiple markets raises the question of each market's share in the discovery of the informationally efficient price. We exploit salient distributional features of multivariate financial price processes to uniquely determine these contributions. Thereby we resolve the...

We use a simple model in which the expected returns in emerging markets depend on their systematicrisk as measured by their beta relative to the world portfolio as well as on the level ofintegration in that market. The level of integration is a time-varying variable that depends on themarket...

This paper develops a model for multi-store competition between firms. Using thefact that different firms have different outlets and produce horizontally differentiated goods, we obtain a pure strategy equilibrium where firms choose a different location for each outlet and firms' locations are...

We present a strategic game of pricing and targeted-advertising. Firms cansimultaneously target priceadvertisements to different groups of customers, or to the entiremarket. Pure strategy equilibria do not exist and thus marketsegmentation cannot occur surely. Equilibria exhibit random...

This paper explores the determinants of regional differences in interest rates based on a simple theoretical model of loan pricing. The model demonstrates how risks, costs, market concentration and scale economies jointly determine the bank's interest rates. Using recent data of the Indonesian...

In this article we study patterns of vertical product differentiation in a multi-product monopoly using a random utility model. Prior research shows that applying such a model in a multi-product setting implies symmetric patterns of product differentiation in which all product variants of a...

This paper assesses the contribution of monetary policy to the dynamics of bond real returns. We assume that the monetary authority controls the short-term nominal interest rate. We then model exogenously the joint dynamics of the aggregate endowment and the monetary policy variable, and...

Following a contractionary monetary policy shock, the aggregate output decreases over time for six to eight quarters, while the real interest rate increases immediately and remains high for three quarters. Full participation models can hardly replicate the joint response of the aggregate output...

In the data, after a contractionary monetary policy shock aggregate output decreases over time, with a trough after four to eight quarters. This paper replicates the `hump-shaped' response of output with a segmented markets model where part of the households are excluded from financial markets....
