The development of risk management methodologies for non-gaussian markets relies often on the assumption that the underlying market factors have a gaussian distribution. While advances have been made in the modeling of more general marginal distributions of the risk factors, the modeling of non-gaussian dependence structures is much less advanced. For commodities markets that often exhibit sudd...

Energy commodities and their futures naturally show cointegrated price movements. However, there is empirical evidence that the prices of futures with different maturities might have, e.g., different jump behaviours in different market situations. Observing commodity futures over time, there is also evidence for different states of the underlying volatility of the futures. In this paper, we the...

In this study we investigate the statistical properties of wholesale electricity spot and futures prices traded on the New York Mercantile Exchange for delivery at the California-Oregon Border. Using daily data for the years 1998 and 1999, we find that many of the characteristics of the electricity market can be viewed to be broadly consistent with efficient markets. The futures risk premium fo...

In this paper we view the problem of adequate electricity supply and demand as a dynamic process affected by several fundamental factors. By incorporating the effect of the available price signals on investment decisions we model the investment dynamics for (i) a system comprising both spot and futures (forward) markets, and for (ii) a system comprising a spot and an installed capacity (ICAP) m...

Strengthening institutions in spot and derivative markets for commodities is a necessary ingredient of the liberalisation process in agriculture, and can impact upon the lives of millions. In this paper, we describe the existing market design prevalent on both the spot and the futures markets. We show some evidence on the role played by the nascent futures markets in price discovery. We documen...

Allaz and Vila (1993) show that oligopolistic industries may become more competitive if a futures market is added previous to the spot market. Later, Hughes and Kao (1997) show that this result occurs only if positions in the futures market are observed, and that without this condition the result is again the Cournot equilibrium. In this work we study different explicit formulations of observab...

Using a spillover index approach, we investigate volatility spillovers across China’s stock, bond, commodity futures, and foreign exchange (FX) markets and their evolution during the period 2005–2015. We find that these four financial markets are weakly integrated. The stock market is the largest net sender of volatility spillovers to other markets, followed by the bond market, and the FX and c...

In 2003, trading of commodity futures shifted from single commodity, regional exchanges to national exchanges that trade multiple commodities. This paper examines price discovery and hedging effectiveness of commodity futures after this change and concludes that,on average, futures prices do discover information relatively efficiently,but helps to manage risk less efficiently. The paper uses th...

Research on the impact of the introduction of derivatives on the market volatility has reported mixed evidences. In this paper, we study the volatility implications of the introduction of derivatives on the stock market in India using S&P CNX IT index. To account for the heteroscedasticity in the time series, GARCH model is used. We find clustering and persistence of volatility in different deg...
