Modelling information and hedging: the exporting firm

The paper examines the economic role of modelling information on the decision problem of an exporting firm under exchange rate risk and hedging. Information is described in terms of market transparency, i.e., a publicly observable signal conveys more information about the random foreign exchange rate. We analyze the interaction between market transparency and the ex ante expected utility of the exporting firm. It is shown that more transparency on the foreign exchange market may result in higher or lower export production. --Information,transparency,exchange rate risk,hedging,trade

The Competitive Firm Under Price Uncertainty: The Role of Information and Hedging

We study the impact of transparency in a commodity market on the decision problem of a competitive firm under price uncertainty and hedging opportunities. Market transparency is modeled by means of the informational content of publicly observable signals which are correlated with the random price. We find that the impact of more transparency on labor employment and production depends on the firm's technology. Inparticular, more transparency may result in lower average output even though on average more labor has been used in the production process. We also analyze the link between market transparency and the welfare of the firm. --Transparency,information system,price uncertainty,hedging,competitive firm

A Note on Hedging a Loan Portfolio

In the framework of the industrial economics approach to banking we extend the analysis of hedging against default on loans to the case of two types of credit risk. Standard results on the optimal hedge volume and the hedging effectivity from the single-risk case are shown to carry over to the portfolio case in a non-trivial but intuitive way.banking, credit risk, loan portfolio, credit derivative, hedging effectivity

Transparency in the foreign exchange market and the volume of international trade

In this paper we study the impact of more transparency in the foreign exchange market on the ex ante expected volume of international trade. Transparency is measured by the informational content of publicly observed signals correlated to the random exchange rate. We find that more transparency may increase or decrease the volume of international trade. In particular, the impact of more transparency depends the curvature of the marginal cost function of the firms. Furthermore, ex ante expected profits of the firms are higher when the foreign exchange market is more transparent. --exchange rate risk,transparency,export production,futures markets

German Foreign Direct Investment and Wages

Over the last decade, German multinationals created about two million jobs abroad with increasing foreign direct investment (FDI). While there are many reasons for firms to go multinational and probably just as many for Germany's high unemployment, this paper aims to investigate the relationship between domestic labour costs and foreign direct investment. We apply a theoretical model for an econometric analysis examining the determinants of FDI using panel data of German firms' foreign capital stocks in 22 countries between 1994 and 2003. Estimating elasticities, we find that while domestic wages do not significantly influence total FDI by German firms, they positively affect the FDI stock in countries where cheap labour is abundant. Thus, although Germany's high labour costs are not the sole driver of foreign direct investment, they may accelerate the outsourcing of German jobs. --Foreign direct investment,wages,trade,German multinational firms

Transparency in the Interbank Market and the Volume of Bank Intermediated Loans

In this paper we study the impact of more transparency in the interbank market on the volume of bank intermediated loans and on the profitability of the banking business. Transparency is modeled by means of the informational content of publicly observable signals correlated to the random interbank interest rate. We find that more transparency may increase or decrease the volume of bank loans. In particular, the impact of more transparency on the volume of loans depends on the curvature of the marginal cost function of the banking firm. Furthermore, we find that ex ante expected profits of the bank are higher when the interbank market is more transparent. --banking firm,interbank market,interest rate risk,hedging,transparency

Authoring Support for Mobile Interaction with the Real World.

Mobile phones have been established as devices for the interaction with objects from the everyday world, such as posters, advertisements or points of interest. However, the usage of physical mobile applications is often still restricted by fixed content and behavior, whose authoring usually requires a considerable coding effort. This paper presents an approach to an authoring tool that separates the creative process of authoring content and behavior for mobile applications from its technical deployment. The tool supports non-technical users in the creation of content and behavior for the mobile guiding application MOPS that associates its content with points of interest in the real world through Physical Mobile Interaction

The effect of exchange rate risk on US foreign direct investment: an empirical analysis

This paper empirically analyzes the impact of exchange rate uncertainty, exchange rate movements and expectations on foreign direct investment (FDI). Two competing specifications of exchange rate volatility are examined. The investigation is based on a cross-section time-series data set of U.S. outward FDI by industries to six major partner countries for the period 1984-2004. Using the standard deviation of the real exchange rate as a measure of risk it is found that exchange rate uncertainty has a discouraging effect on FDI flows across all industries. This is contrasted when applying an alternative risk specification defined as the unexplained part of real exchange rate volatility. Now, results show a clear distinction between non-manufacturing and manufacturing industries. U.S. FDI outflows in nonmanufacturing industries exhibit a positive correlation with increased exchange risk, whereas this relationship is negative for manufacturing industries in the underlying sample. A real appreciation of host-country currency was associated with higher FDI flows, while expectations about an appreciation showed a negative result. --Foreign direct investment,real exchange rate risk,volatility
