The majority of risk adjusted performance measures (RAPM) currently in use – e.g., Treynor ratio, (?/?)) ratio, Omega index, RoVaR, ‘coherent’ preference criteria, etc. – are incompat- ible with any sensible utility function and would be best avoided. We argue instead for the assessment...

In the past decades, the amount of worldwide security transactions that was processed by electronic trading platforms increased significantly. In this paper we develop a theoretical framework for the pricing of limit orders of the Electronic Security Trading System Xetra operated by the German...

Against the backdrop of the theories developed in the real options and financing constraints literatures, this paper examines the impact of profit uncertainty and sunk costs on firms’ entry and exit decisions. For our empirical analysis, we compile an extensive dataset containing information...

We use a natural experiment to investigate the impact of participation constraints on individuals' decisions to invest in the stock market. Unexpected inheritance due to sudden deaths results in exogenous variation in financial wealth and allows us to examine whether fixed entry and ongoing...

This paper studies recursive exchange economies with short sales. Agents maximize discounted expected utility. The asset structure is general and includes real securities, infinite-lived stocks, options, and other derivatives. The main result shows the existence of a competitive equilibrium...

We set out to study stock price manipulation when the manipulator is in the role of an intermediary (broker). We find that in the absence of superior information, the broker can manipulate equilibrium outcomes without losing its credibility with respect to accurate forecasting. The result...

This paper presents a generalized serial covariance spread pricing model that unifies and improves existing spread models. We analyze three cost components of spread: order processing, adverse information, and inventory holding costs. We modify Stoll's (1989) model by incorporating a two-period...

We present a new model of forward dynamic utilities. In doing so, we provide unique (viscosity) solutions. In addition, we introduce Hausdorff-continuous viscosity solutions to the portfolio model.

We analyze a rational-expectations model of information acquisition and price formation in an intermediate- good market: prices and net supply are non-negative, there are no noise traders, and the intermediate good has multiple potential uses. Several of our results differ from the classic...
