We analyse questions of arbitrage in financial markets in which asset prices change in time as stationary stochastic processes. The main focus of the paper is on a model where the price vectors are independent and identically distributed. In the framework of this model, we find conditions that...

The paper shows that financial market equilibria need not exist if agents possess cumulative prospect theory preferences with piecewise-power value functions. The reason is an infiniteshort-selling problem. But even when a short-sell constraint is added, non-existence can occur due to...

We study properties of structured financial products optimizing a utility functional of a customer. The conventional method may have the disadvantage that the a priori restriction to a certain number of assets could make it impossible to find the optimal portfolio. So instead of optimizing the...

This paper studies how the investors’ attitude towards earnings surprises affects the managers’ incentives to manipulate earnings in an intertemporal context, where the consensus forecast of the analysts is not exogenously given but determined by the strategic interaction between the analysts...

This paper determines the value of asset tradeability in an option pricing framework.In our model, tradeability is valuable since it allows investors to exploit temporary mis-pricings of stocks. The model delivers several novel insights on the value of tradeability:The value of tradeability is...

Market mechanisms are increasingly being used as a tool for allocating somewhat scarce but unpriced rights and resources, such as air and water. Tradable permits have emerged as the most cost effective measure leading to the emergence of both nationwide (SO2 ) and supranational (CO2 ) emission...

Episodes of unanticipated inflation reduce the real value of nominal claims and thus redistribute wealth from lenders to borrowers. In this study, we consider redistribution as a channel for aggregate and welfare effects of inflation. We model an inflation episode as an unanticipated shock to...

This paper asks whether tax cycles can represent the optimal policy in a model without any extrinsic uncertainty. I show, in an economy without capital and where labor is the only choicevariable (a Lucas-Stokey economy), that a large class of preferences exists, where cycles are optimal, as well...

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....

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,...
