We investigate the term structure for the case when interest rates are allowed to be driven by a general marked point process as well as by a Wiener process. Developing a theory which allows for measure-valued trading portfolios we study existence and uniqueness of a martingale measure, as well...

This paper analyzes the effects on present consumption of budget deficits under different assumptions regarding demographics. In the first part, birth and death rates are deterministic, and in the second part, birth rates are assumed to be stochastic. In the case of a deterministic population...

In order to determine to what extent capital investments are sunk costs this study deals with salvage values of discarded metalworking machinery. Even though these assets are expected to be non-specific many of the discarded assets are scrapped rather than sold on second-hand markets....

The paper argues that sellers sometimes impose exclusivity clauses on their buyers in order to prevent arbitrage between brands. In a duopoly model in which the sellers compete through fairly general long term contracts, it is shown that common agency is always allowed whenever reselling can be...

Employee share ownership is growing increasingly important. This paper studies employee share ownership in an economy with one monopoly union for each firm. We modify an implicit contra t model by adding dividend income to the usual wage income. Union members differ in exogenous stock endowments...

The paper explores the question of whether markets under laissez-faire will be able to insulate an economy from bad government money. Some recent proposals favour freezing the monetary base, by abandoning central bank operations. This requires active participation by the monetary authorities,...

Within the framework of transitive sufficient processes we investigate identifiability properties of unknown parameters. In particular we consider unbiased parameter estimators, which are shown to be closely connected to time reversal and to reverse martingales. One of the main results is that,...

The paper analyzes the effects on consumption from changes in the riskiness of taxes. It starts by reinterpreting the Sandmo [1970] paper on general capital income risk to the case of risky capital taxation. In his framework the concept of a mean preserving spread (MPS) is used for the risk...

In this paper we derive an exact relationship between the net investment at a given point in time and future consumption plans. Our result is general in the sense that it neither requires a constant rate of time preference nor an exponential discount function. One interpretation of the result is...

Two terms of a second-order approximation to the bias of the multivariate OLS estimate are derived using the same technique as in Nicholls and Pope (1988). The resulting second-order bias approximation is then tested against first-order alternatives on two bivariate Monte Carlo sijmulated VAR...
