Stock picking is the field of financial analysis that is of particular interest for many professional investors and researchers. In this study stock picking is implemented via binary classification trees. Optimal tree size is believed to be the crucial factor in forecasting performance of the...

Independent component analysis (ICA) is a modern factor analysis tool developed in the last two decades. Given p-dimensional data, we search for that linear combination of data which creates (almost) independent components. Here copulae are used to model the p-dimensional data and then...

This paper contributes to the micro-foundation of money in centralizedmarkets with idiosyncratic uncertainty. It shows existence of stationarymonetary equilibria and ensures that there is an optimum quantity ofmoney. The rational solution of our model is compared with actual be-havior in a...

Central bankers’ conventional wisdom suggests that nominal interest rates should be raised to implement a lower inflation target. In contrast, I show that the standard New Keynesian monetary model predicts that nominal interest rates should bedecreased to attain this goal. Real interest rates,...

This paper extends a New Keynesian model to include roles for currency and depositsas competing sources of liquidity services demanded by households. It showsthat, both qualitatively and quantitatively, the Barnett critique applies: While a Divisiaaggregate of monetary services tracks the true...

This paper examines whether the existence and the timing of real balance effects contribute to the determination of the absolute price level, as suggested byPatinkin (1949,1965), and if they affect conditions for local equilibrium uniqueness and stability. I show that there exists a unique price...

This paper examines how money demand induced real balance effects contribute to the determination of the price level, as suggested by Patinkin (1949,1965), and if they affect conditions for local equilibrium uniqueness and stability. There exists a unique price level sequence that is consistent...

This paper studies the joint business cycle dynamics of inflation, money growth, nominal and real interest rates and the velocity of money. I extend and estimate a standard cash and credit monetary model by adding idiosyncratic preference shocks to cash consumption as well as a banking sector....

Based on an experimental analysis of a simple monetary economy we argue that a monetary system is more stable than one would expect from individual rationality. Weshow that positive reciprocity stabilizes the monetary system, provided everyparticipant considers accepting money as a reasonable...

Tobin (1958) has argued that in the face of potential capital losses on bonds it is reasonable to hold cash as a means to transfer wealth over time. It is shown that this assertion cannot be sustained taking into account the evolution of wealth of cash holders versus non cash holders. Cash...
