The demand for hedging against price uncertainty in the presence of crop yield and revenue insurance contracts is examined for French wheat farms. The rationale for the use of options in addition to futures is first highlighted through the characterization of the first-best hedging strategy in the expected utility framework. It is then illustrated using numerical simulations. The presence of op...

Abstract: This study analyzes two issues related to the GKO futures market in Russia in 1996 and 1997. First, we evaluate the existence of a risk premium in this market. We show its existence providing a functional form for the premium. The main result is that risk premium depends positively on the time before delivery of the futures contract. We provide anecdotal evidence in support of our res...

Based on the multifractal detrended fluctuation analysis (MF-DFA) and multifractal spectrum analysis, this paper empirically studies the multifractal properties of the Chinese stock index futures market. Using a total of 2,942 ten-minute closing prices, we find that the Chinese stock index futures returns exhibit long-range correlations and multifractality, making the single-scale index insuffi...

The possibility that hedge fund trading destabilizes or creates a volatile market is frequently debated. This hypothesis is in stark contrast to the traditional speculative stabilizing theory that profitable speculation must involve buying when the price is low and selling when the price is high. To test the hypothesis that hedge fund trading is destabilizing we employ a unique dataset from the...

We provide an analytical discussion of the optimal hedge ratio under discrepancies between the futures market price and its theoretical valuation according to the cost-of-carry model. Assuming a geometric Brownian motion for spot prices, we model mispricing as a speci...c noise component in the dynamics of futures market prices. Empirical evidence on the model is provided for the Spanish stock ...

The views expressed herein are those of the author(s) and do not necessarily reflect the views of the National Bureau of Economic Research. ABSTRACT We conduct a comprehensive analysis of unspanned stochastic volatility in commodity markets in general and the crude-oil market in particular. We present model-free results that strongly suggest the presence of unspanned stochastic volatility in th...

This paper analyses the validity of the weak-form market efficiency, using the random-walk hypothesis for the six industrial base metals copper, aluminium, zinc, nickel, tin and lead traded at the London Metal Exchange. I analyse the behaviour of daily and weekly prices of the daily rolling three-month futures contracts, as these contracts exhibit the highest level of trading activity. In contr...

An empirical test on long memory between price and trading volume of China metals futures market was given with MF-DCCA method. The empirical results show that long memory feature with a certain period exists in price−volume correlation and a further proof was given by analyzing the source of multifractal feature. The empirical results suggest that it is of important practical significance to b...

We explore optimal hedge ratios and hedging effectiveness for the German electricity market. Given the increasing attention that wavelets received in the financial market, we concentrate on the investigation of the relationship, covariance/coherence evolution and hedge ratio analysis, on a time-frequency-scale approach (discrete and continuous), between electricity spot and futures. Simpler app...
