In this paper, we present a multi-factor continuous-time autoregressive moving-average (CARMA) model for the short and forward interest rates. This model is able to present an adequate statistical description of the short and forward rate dynamics. We show that this is a tractable term structure...

This paper analyzes the weather derivatives traded at the Chicago Mercantile Exchange (CME), with futures and options written on different temperature indices. We propose to model the temperature dynamics as a continuous-time autoregressive process with lag "p" and seasonal variation. The choice...

We discuss the modeling of electricity contracts traded in many deregulated power markets. These forward/futures type contracts deliver (either physically or financially) electricity over a specified time period, and is frequently referred to as swaps since they in effect represent an exchange...

I analyze empirical correlations of electricity forward returns from the perspective of a random field model that specifies the correlations in terms of the temporal separation between forward maturities. It turns out that temporal separation cannot fully account for the empirical forward return...

The potential influence of accounting regulations on hedging strategies and the use of financial derivatives is a research topic that has attracted little attention in both the finance and the accounting literature. However, recent surveys suggest that company hedging can be substantially...

Hedging involves tradeoffs in incomplete markets because the number of hedging instruments is limited. Even when an extensive set of hedging instruments is available, the ease with which these instruments can be traded may be highly variable. This study finds systematic variations in liquidity...

<heading id="h1" level="1" implicit="yes" format="display">Abstract</heading>I investigate the efficiency of alternative hedging strategies of nonfinancial firms facing hedgeable price risk, unhedgeable quantity risk, and financial contracting costs in low-profit events. The analysis suggests that variance-minimizing hedging strategies are very close in economic...

Financial theory suggests that hedging can increase shareholder value in the presence of capital market imperfections, including direct and indirect costs of financial distress, costly external financing, and convex tax exposure. The influence of these costs, which are high when profits are low...

In addition to the ordinary corporate income tax, special purpose taxes are sometimes levied to extract abnormal profits arising from the use of natural resources. Such dual tax regimes exist in Norway for oil and hydropower, where the corresponding special purpose tax bases are unaffected by...

This paper demonstrates that electricity swap returns can be explained by a set of uncorrelated common and unique risk factors. Electricity swap returns differ from return data in other markets by a significant portion of overall risk being unaccounted for by common factors. It follows that...
