| Significant differences exist in the rates of capital adjustment in the four major sectors of the U.S. economy: agriculture, food, manufacturing, and services. A multioutput adjustment cost model is specified to compute the rates of capital adjustment. This specification allows us to derive dynamic output supply and investment demand functions for the four sectors, which are then fitted to time-series data. Our estimates show that capital in agriculture and manufacturing is almost fixed and adjusts toward respective long-run equilibrium at a rate of about 2% per year. The food processing and services sectors are more flexible in that their capital stocks fully adjust in less than five years. Thus, the rate of adjustment of agricultural capital is lower... |

| Derived demand relationships among four weight categories of feeder cattle entering Texas feedlots and feed were examined using a Generalized McFadden dual cost function specified as an error correction model. Relationships among own- and cross-price elasticities provide evidence for at least two cattle feeding enterprises, feeding lightweight feeder cattle (calves) and feeding heavier cattle. These results indicate systematic differences in demand relationships among the different weight classes, providing explanation and insight into mixed results from earlier studies. Seasonality differed across weight categories, providing additional support for multiple cattle feeding enterprises. A third step was added to the Engle-Granger two-step estimation... |

| The relationship among cost functions, distance functions, and technical inefficiency are utilized to show how technical inefficiency scores can be incorporated into the specification of a profit function and a related system of output supply and input demands. A method also is introduced for incorporating allocative efficiency scores into the same system. The theoretical and empirical approach requires fewer assumptions than those made in many studies. An illustrative example is provided for Russian agriculture for 1194-95, a period when significant technical and allocative inefficiency was known to exist. The results demonstrate inefficiency limits the supply response to prices, thus leading to lower estimates of output response compare to a... |

| In 2006 FDA announced that consumers should not eat fresh spinach in the wake of a large foodborne illness outbreak of E. coli O157:H7. This paper investigates response of consumers to the announcement. We use an AIDS demand model with 5 food safety shock variables and retail scanner data to analyze market response. Even fifteen months after the outbreak, predicted sales of spinach in bags were still down 10 percent from what they would have been in the absense of the food safety shock. After the outbreak, consumers shifted to other leafy greens such as bulk iceberg lettuce, other bulk lettuce, and bagged salads without spinach. |

| This paper examines domestic and international food market integration in Russia before and after the financial crisis of 1998. Using monthly prices of bread, pork, and beef in 80 regions of Russia from 1994 to 1999, we measure the short-run response of regional prices to changes in foreign prices and domestic inflation. We find that both changes in foreign prices and domestic inflation have distinct impacts on the prices of these commodities in different Russian markets, indicating poor market integration in the short run. An analysis of the effect of the financial crisis shows that market integration for bread and beef deteriorated after the crisis. However, integration improved for pork in some parts of Russia, and the integration of Siberian pork... |

| In this paper we evaluate the performance of a dynamic model of cattle replacement and culling decisions. We derive the price of cattle when it is treated as a unit of capital and evaluate various rates of adjustment of the cattle herd to determine the length of the cattle cycle. Replacement decision is modeled as the solution to a dynamic optimization problem where the breeding herd is viewed as a capital asset that is capable of producing two outputs: calves and culled cows. The own-price, replacement and interest rate elasticities calculated for both the short-run and long-run time-frames suggest fairly rapid adjustment rates. Tests of cycle length revealed a 14-year cattle cycle. |

| This paper explores the time series properties of cattle and feed prices to determine the effect shocks may have on price evolution. Two different unit roots tests are applied to the data and compared and the issue of fractional integration is discussed. A Geweke Porter-Hudak test finds that at least of three of the four price series are fractionally integrated. VAR models are estimated using level data and fractionally differenced data and impulse responses compared across various degrees of fractional differencing. |

| Error correction models impose few prior restrictions on dynamic model specification and allow the data to determine model structure. Despite this obvious advantage, few applications have adopted the error correction model to explain trade flows. An error correction model of cotton import demand is estimated for France, Japan, and Hong Kong. A variety of tests are applied to determine the dynamic structure of the model. We find the most general models are those that best fit the data for cotton import demand. Long-run elasticities from these general models are significantly different than elasticities derived from a comparable static model. |

| Most previous estimates of elasticities of export demand for U.S. soybeans have emanated from single import equations subject to aggregation and simultaneous equation bias. This analysis tests U.S. soybean export data for aggregation and simultaneous equation bias and divides the aggregated data into six market equations to reduce these biases. Elasticity estimates from the six equations are compared with elasticity estimates from single equation OLS and 2SLS estimations using the same aggregate data. Results suggest that distortions from unjustified 2SLS estimation may exceed those from aggregation bias. |
