This paper examines necessary conditions for a demand for new information to exist. In this one-period model, investors are homogeneous, have logarithmic utility, and must decide on information acquisition before trading starts, and without knowing what other investors will do. We examine the...

The incentive to trade implies that all investors in the market choose to be informed although the whole of them cannot profit from the information signal. This result is due to an insurance property of information.

In this paper we consider a risk averse multinational firm under exchange rate risk. We analyze the impact of exchange rate risk and of the use of currency forwards upon the firm's global market decisions with respect to international firm-specific capital allocation and direct foreign...

We study the impact of exchange rate risk on an exporting firm in a developing country when there is no forward market in the foreign currency. However there exists a forward traded asset in this country the price of which is highly correlated to the foreign currency. By indirectly hedging its...

We derive a class of utility functions that are equivalent with respect to a well-defined functional form. We apply a general view of constant relative risk aversion to investigate on different equivalence relations. Then we compare our results with standard applications in economics and finance.

The economic influence of barriers to international information acquisition and, hence, of informational segmentation in international capital markets depends heavily upon the prevailing level of risk aversion. We find that these barriers are likely to have second order economic impact only....

This paper presents a model of a competitive risk-averse exporting firm under exchange rate risk. We show that export and hedging decisions can be separated if futures and currency options are available. A full hedge of uncertain export revenue occurs if the futures market is unbiased and the...

This paper presents a model of a competitive risk averse exporting firm under exchange rate uncertainty. If forward market contracts are available neither the distribution parameters of the exchange rate nor the degree of the firm's risk aversion have any impact on the export level. But this...

The paper focusses on currency options as financial hedging instrumenta. Since currency forwards imply the well-known Separation result, it follows for arbitragefree hedging markets that Separation must also hold in option markets if the traded options allow for con-structing a synthetical...
