Exchange Rate Forecasting Techniques, Survey Data, and Implications for the Foreign Exchange Market

Abstract: The paper presents new empirical results that elucidate the dynamics of the foreign exchange market. The first half of the paper is an updated study of the exchange rate expectations held by market participants, as reflected in responses to surveys, and contains the following conclusions. First, the bias observed in the forward discount as a predictor of the future spot rate is not attributable to an exchange risk premium, as is conventionally believed. Second, at short horizons forecasters tend to extrapolate recent trends, while at long horizons they tend to forecast a reversal. Third, the bias in expectations is robust in the samples, based on eight years of data across five currencies. The second half of the paper abandons the framework in which all market participants share the same forecast, to focus on the importance of heterogeneous expectations. Tests suggest that dispersion of opinion, as reflected in the standard deviation across respondents in the survey, affects the volume of trading in the market, and, in turn, the degree of volatility of the exchange rate. An example of how conflicting forecasts can lead to swings in the exchange rate is the model of "chartists and fundamentalists." The market weights assigned to the two models fluctuate over time in response to recent developments, leading to fluctuations in the demand for foreign currency. The paper ends with one piece of evidence to support the model: the fraction of foreign exchange forecasting services that use "technical analysis" did indeed increase sharply during 1983-85, but declined subsequently.

Pricing electricity derivatives within a Markov regime-switching model: a risk premium approach

Abstract: In this paper we derive analytic formulas for electricity derivatives under assumption that electricity spot prices follow a 3-regime Markov regime-switching model with independent spikes and drops and periodic transition matrix. Since the classical derivatives pricing methodology cannot be used in the case of non-storable commodities, we employ the concept of the risk premium. The obtained theoretical results are then used for the European Energy Exchange data analysis. We calculate the risk premium in the case of the calibrated 3-regime MRS model. We find a time varying structure of the risk premium and an evidence for a negative risk premium (or positive forward premium), especially at short times before delivery. Finally, we use the obtained risk premium to calculate prices of European options written on spot, as well as, forward prices.

Impact of Wind Power Generation on European Cross-Border Power Flows

Abstract: A statistical analysis is performed in order to investigate the relationship between wind power production and cross-border power transmission in Europe. A dataset including physical hourly cross-border power exchanges between European countries as dependent variables is used. Principal component analysis is employed in order to reduce the problem dimension. Then, nonlinear relationships between forecast wind power production as well as spot price in Germany, by far the largest wind power producer in Europe, and power flows are modeled using local polynomial regression. We find that both forecast wind power production and spot price in Germany have substantial nonlinear effects on power transmission on a European scale.

Asian Spot Prices for LNG and Other Energy Commodities

Abstract: We investigate the relationship between the Japan-Korea Marker (JKM) price of LNG, which has become more important as spot trading of LNG has increased, and spot prices of Brent oil, fuel oil and thermal coal in Asia. We find that the JKM price appears to reflect inter-fuel competition in Asia. In this respect, it could be better than oil or other spot natural gas prices as a reference price for indexing long-term LNG contracts in Asia. The JKM may also be suitable for underpinning the development of an LNG pricing hub in Asia with associated derivatives markets.
