| Recent theory on exchange rate dynamics suggests that the mere announcement of regime switching from floating to fixed rates at a given future date triggers a reduction in exchange rate volatility during the interim period. Using a Markov-switching GARCH model this paper estimates the volatility processes of four EMU exchange rate returns vis-à-vis the German mark using daily data for the time prior to Stage III of EMU. Statistical inference yields the dates at which financial markets began to incorporate the expected EMU participation of each country into currency pricing. The data exhibits strong econometric evidence for two distinct views concerning the ultimate EMU membership: (1) Finland and France were considered irrefutable EMU members long before... |

| Despite the fact that there is a substantial literature on the analysis of volatility spillovers between stock returns and domestic exchange rates, surprisingly, little empirical research has examined volatility spillovers between oil prices and emerging economies, where a clear gap of research have been found regarding to the BRIC financial markets and the effects of the 2007-2009 World economy crisis. This lack of research might appear as surprising given that energy markets are of particular interest as they are considered a fundamental reference for economic recovery and growth. Therefore, this work aims to address this gap on the literature by looking at the BRIC financial markets and their co-movements with regard to some energy markets (oil, natural... |

| VaR gives a prediction of potential portfolio losses, with a certain level of confidence, that may be encountered over a specified time period due to adverse price movements in the portfolio's assets. For example, a VaR of 1 million dollars at the 95% level of confidence implies that overall portfolio losses should not exceed 1 million dollars more than 5% of the time over a given holding period. This research examines the effectiveness of VaR measures, developed using alternative estimation techniques, in predicting large losses in the cattle feeding margin. Results show that several estimation techniques, both parametric and non-parametric, provide well calibrated VaR estimates such that violations (losses exceed the VaR estimate) are commensurate... |

| The objective of this work is to determine the presence of volatility in the spot and futures exchange rates, detecting, thus, the presence of risk. Identified the volatility, it is looked for shaping it through the construction of models capable to forecast the behavior of the spot and futures exchange rates. The GARCH and TARCH models had been used to shape the volatility of the exchange rates. Gotten the estimates, it is verified existence of convergence of these rates in the date of the expirations of future contracts, identifying, thus, the chance to get profits with arbitrage. The results had shown more that the spot and futures exchange rates are very volatile and the spot exchange market presents asymmetry, being affected for negative impacts. The... |

| We study the difference in the volatility dynamics of CBOT corn, soybeans, and oats futures prices across different delivery horizons via the smoothed Bayesian estimator of Karali, Dorfman, and Thurman (2010). We show that the futures price volatilities in these markets are affected by the inventories, time to delivery, and the crop progress period. Some of these effects vary across delivery horizons. Further, it is shown that the price volatility is higher before the harvest starts in most of the cases compared to the volatility during the planting period. These results have implications for hedging, options pricing, and the setting of margin requirements. |

| Globalization and trade liberalization have exposed agricultural sector of many developing countries to sudden disturbances, caused not just by demand-supply conditions within their economies but also by volatility in global commodity prices, exchange rate and surge in imports. This paper evaluates the magnitude of sensitivity of Indian agriculture to these factors, and explores policy options that may neutralize their adverse effects, maintain price incentives and stability. The analysis is undertaken for one important tradable commodity viz. wheat by applying a structural econometric model, separately under the exportable and importable scenarios from 1980-81 to 2009-10. Findings reveal wheat to be increasingly driven by an incentive structure based on... |

| Low trading volume in the CME stocker cattle contracts has made hedgers and speculators reluctant to use the contracts. Traders need decision tools to discover prices or to evaluate quoted prices that may not contain all the information in the market. The number of head of stocker weight cattle sold on the spot market has increased in recent years while the practice of cross-hedging stocker weight cattle against the feeder cattle contract remains risky. A model explains the spread between feeder cattle and stocker cattle futures prices as a function of feed prices, live cattle prices, and seasonal factors. The volatility of spot stocker cattle prices is comparable to spot feeder cattle prices, supporting the idea of using feeder cattle implied volatility... |

| In this paper we use weekly milling wheat price series for nine selected EU countries to evaluate levels and components of volatility in the period from July 2004 to April 2011 and to examine how sensitive the results can be to spatial aggregation of the price data. The prices were analyzed in levels and logarithmic rate of returns. To asses price risk, apart from basic measures of price variability, the price series were decomposed using multiplicative model in order to determine shares of seasonal and random components in the total variance of the prices. We also applied ARMAX model to separate the stochastic components of the price series to properly evaluate real price risk exposure and tested for ARCH and GARCH effects. We found considerable... |

| Climate volatility will increase in the future, with agricultural productivity expected to become increasingly volatile as well. For Tanzania, where food production and prices are sensitive to the climate, rising climate volatility can have severe implications for poverty. We develop and use an integrated framework to estimate the poverty vulnerabilities of different socio-economic strata in Tanzania under current and future climate. We find that households across various strata are similarly vulnerable to being impoverished when considered in terms of their stratum’s populations, with poverty vulnerability of all groups higher in the 21st Century than in the late 20th Century. When the contributions of the different strata to the national poverty changes... |

| A modified gravity-type model was employed to evaluate the effect of exchange rate volatility on wheat exports worldwide. Special attention was given to the econometric properties of the gravity model within panel framework. Short and long-term measures of exchange rate volatility were constructed and compared. Both measures of exchange rate volatility have exhibited a negative effect on world wheat trade and the long-term effect was even larger. This result implies that exchange rate volatility is an important factor in explaining the trade pattern of wheat trade worldwide. Keywords: wheat, export, exchange rate, volatility, gravity model, and panel data. |

| We estimate in this paper the market risk implied by the prices of different options traded in the Brazilian stock market. The fundamental theory to handle this problem is the one implied by the Arrow-Debreu contingent claim concept. Using that theory, we are able to construct the term structure of market risk, and to obtain a surface that provides slices for a particular “volatility smile.” The methodology that we use follows the one proposed by Shimko (1993), which is able to calculate a non-lognormal probability density function (PDF) consistent with the volatility observed in a relatively small sample of option prices. This methodology goes beyond the one proposed originally by Black and Scholes (1973), since it does not require log-normality of the... |
