Coffee price volatility was extreme in 1997. With no obvious drought or freezing conditions in major growing countries, market analysts blamed El Nino. Alternatively, economic theory implies that commodity price volatility should be high when inventories are low. We analyze and test these two...

Agricultural prices are determined by natural and socio-economic factors that are known to be self-similar at different time scales and to follow non-periodic cyclical patterns. These properties are most easily understood using Mandelbrot's fractal geometry, in which a jagged time series is...

Organic vegetable producers typically earn a premium over conventional producers to cover the added costs of organic production. The premium can vary greatly, making organic vegetable farming riskier than conventional farming and causing potential financial problems for new organic farming...

Standard models of hedging behavior assume that either hedgers wish to minimize net price variation or they wish to balance variation versus profits. These models treat variation as risk and fail to distinguish between variation that is random and variation that is not random over time. Newer...

In this paper we study the trade creation effects of the EU preferential trade agreements (PTAs) in the agriculture and food sectors for a large sample of developing countries in the period 1990-2006. We build upon the existing literature on trade with heterogeneous firms, by investigating the...

Using a unique dataset of maize samples and consumer interviews form Eastern Kenya, we find that the presence of the fungal contaminant aflatoxin is negatively associated with the use of maize flour for food. While food remains the most common use of maize regardless of the presence of the...

Is the relationship between energy and agricultural commodities an important factor in the increasing price variability of food commodities? Findings from the literature appear to be mixed and highly influenced by the data frequency used in those analysis. A recurrent task in time series applied...

The United States cheese consumption has grown considerably over the years. Using Nielsen Homescan panel data for calendar years 2005 and 2006, this paper examines the effect of economic and socio-demographic factors on the demand for disaggregated cheese varieties. In this study, we estimated...

We exploit variation in the timing of specialty crop insurance supply to different crops and counties in California to assess its effect on output as decomposed into yield and harvested acreage. Four woody-perennial crops and one field-annual crop are used to represent this effect. We find that...

The Gulf of Mexico (GOM) is the primary producer of shrimp in the United States and annual production from this region has remained relatively constant over the past several decades. By comparison, U.S. shrimp imports have increased from about 400 million pounds annually during the early 1990s...
