| The goal of this experimental study was to test an effectiveness of a group contract designed to control nonpoint source water pollution from farms' runoff (Pushkarskaya 2003). In particular, the regulator pays for pollution reduction credits earned by the group of the farmers, who voluntary enter the contract, and is concerned only with the total level of the abatement achieved, while the group of farmers undertakes responsibility to distribute the payment so as to induce the farmers to deliver the desired level of abatement. First round of experiments was conducted using as subjects undergraduate students from the Ohio State University, second round of experiments was conducted using as a subjects Kentucky farmers, who would be an actual subjects to... |

| The effectiveness of the Class III Milk futures market is analyzed in terms of the reduction in Value-at-Risk (VaR) for milk producers located in four regions: Wisconsin, Northeast, Florida and California. Constant hedge ratios are estimated using Myers and Thompson's (1989) generalized conditional hedge ratio technique, and time-varying hedge ratios are estimated using an exponentially weighted moving average method. After defining milk price risk as the deviation of the actual milk price from its expected value, the effectiveness of uniform hedging strategies in the Class III milk futures market is assessed using three popular methods for VaR calculations: the parametric method, the historical method, and the Monte Carlo simulation method. The results... |

| Coffee and cocoa are two agricultural commodities produced mainly in developing countries and exported almost entirely to high income industrialized countries. The international market for these products is marked by high price instability. This paper investigates whether monetary policy disturbances contribute to cocoa and coffee price instability. Monthly time series data were collected for five variables including agricultural prices, industrial prices, money supply, exchange rate, and interest rate. A Vector Error Correction model is used to investigate whether cocoa and coffee prices overshoot in response to unanticipated monetary shock. The econometric evidence points toward overshooting of cocoa, arabica coffee and robusta coffee prices in the... |
