Consumer Price Formation with Demographic Translating AgEcon
Piggott, Nicholas E..
We investigate how to theoretically and empirically incorporate demographic translating in consumer distance functions. Consumer distance functions yield inverse demand systems that are of interest when attempting to better understand questions of price formation. Translating procedures are important when incorporating pre-committed quantities, pre-allocated factors, or demographic variables (e.g., advertising, health or food safety information) in the inverse demand system. Examples are included for illustrative purposes.

Spatio-temporal Risk and Severity Analysis of Soybean Rust in the United States AgEcon
Bekkerman, Anton; Goodwin, Barry K.; Piggott, Nicholas E..
Soybean rust is a highly mobile infectious disease and can be transmitted across short and long distances. Soybean rust is estimated to cause yield losses that can range between 1%-25%. An analysis of spatio-temporal infection risks within the United States is performed through the use of a unique data set. Observations from over 35,000 field-level inspections between 2005 and 2007 are used to conduct a county-level analysis. Statistical inferences are derived by employing zero-inflated Poisson and negative binomial models. In addition, the model is adjusted to account for potential endogeneity between inspections and soybean rust finds. Past soybean rust finds and inspections in the county and in the surrounding counties, weather and overwintering...

The Impacts of Food Safety Information on Meat Demand: A Cross-Commodity Approach Using U.S. Household Data AgEcon
Piggott, Nicholas E.; Taylor, Mykel R.; Kuchler, Fred.
The potential impacts of a food safety event on consumer demand for meat is of significant concern to producers, packers, processors, retail businesses, and the USDA. This study investigates whether publicized food safety information from the printed media on beef, pork, and poultry, impacts the demand for these commodities. A four commodity complete demand system is employed using monthly household level data on meat purchases collected by the Nielsen Company, with separate food safety indices incorporated for beef, pork, and poultry. Results from the analysis indicate that consumers purchase relatively high levels of pre-committed quantities of pork, chicken, and turkey, while beef consumption appears to be primarily from supernumerary expenditures....

SPATIAL MARKET INTEGRATION IN THE PRESENCE OF THRESHOLD EFFECTS AgEcon
Goodwin, Barry K.; Piggott, Nicholas E..
Threshold cointegration models are used to evaluate spatial price dynamics among regional corn and soybean markets in North Carolina. Thresholds, reflecting the influences of transactions costs, are confirmed and spatial integration is strongly supported. Results indicate that equilibrating adjustments to market shocks are generally complete in two weeks.

INTERACTION EFFECTS OF PROMOTION, RESEARCH, AND PRICE SUPPORT PROGRAMS FOR U.S. COTTON AgEcon
Beach, Robert H.; Murray, Brian C.; Piggott, Nicholas E.; Wohlgenant, Michael K..
Many agricultural commodities have industry-funded generic promotion and/or research (“"checkoff”") programs designed to improve the economic performance of producers. To determine the effectiveness of these programs, the net benefits to producers attributable to activities funded by the checkoff must be separated from those due to other factors influencing commodity markets. One such factor that is very important in many agricultural commodity markets is the effect of government programs. However, studies evaluating the returns to checkoff programs often do not explicitly discuss the impact of pre-existing distortions caused by federal farm programs. Because the distortions caused by farm programs can be quite large, this omission can lead to...

The Impact of Pork Advertising on US Meat Demand in the Presence of Competing Beef Advertising and Food Safety Events AgEcon
Piggott, Nicholas E.; Zhen, Chen; Beach, Robert H.; Wolhlgenant, Michael K..
We examine the effects of domestic advertising and promotion expenditures on meat demand, extending previous efforts in several areas, including the use of more recent data, employing a complete demand system and simultaneously measuring the impacts of generic pork and beef advertising and food safety information on the demand for beef, pork, and poultry. Using the Generalized Almost Ideal Demand System (GAIDS), own- and cross- beef and pork advertising and own- and cross- beef, pork, and poultry food safety effects are measured jointly and consistently. To allow for a more complex dynamic response of advertising and food safety effects, the flexible distributed lag technique of Mitchell and Speaker (1986) is employed. The coefficients on pork advertising...

Price elasticities, joint products, and international trade AgEcon
Piggott, Nicholas E.; Wohlgenant, Michael K..
This paper extends the basic results of Houck’s insight for derived demand elasticities for the case of joint products by allowing for the possibility of the joint and raw products being traded. Theoretical relationships between individual demands for a set of jointly-produced commodities that are traded and composite demand for the raw product from which the joint products originate are derived. It is shown that while the derived price elasticity of domestic demand retains the same form as Houck’s original formula, the relevant price elasticities of demand to include in the formula are elasticities of total demand instead of domestic demand elasticities. Using the USA soybean industry as an example, this generalised formula that takes into account trade...

Measuring Part-Whole Bias: Some Evidence from Crop Biotechnology AgEcon
Marra, Michele C.; Piggott, Nicholas E..
We analyze the non-pecuniary aspects of some crop biotechnologies taken from three farm-level surveys. We focus particularly on the phenomen on of part-whole bias, which is the empirical finding that the sum of the stated part-worths (the value of each nonpecuniary characteristic) is greater than the stated total value of all the non-pecuniary characteristics. We analyze the empirical evidence of part-whole bias in the surveys, while decomposing it to further understand the phenomenon and to rescale the stated values of the non-pecuniary characteristics in the surveys. We find for all three surveys that the degree to which part-worths should be rescaled is about 60 percent.

FROM CONSUMER CHOICE PROCESS TO AGGREGATE ANALYSIS: MARKETING INSIGHTS FOR MODELS OF MEAT DEMAND AgEcon
Piggott, Nicholas E.; Wright, Vic.
The presence or absence of structural change in meat demand is critical to marketing decision making. If change is present, marketing bodies need to know what underlies the change so that the most appropriate response can be identified. Marketing theory is considered as a possible source of more explicit models of demand which may lead to a better understanding of consumption patterns and structural change.

Spatial Analysis of Market Linkages in North Carolina Using Threshold Autoregression Models with Variable Transaction Costs AgEcon
Bekkerman, Anton; Goodwin, Barry K.; Piggott, Nicholas E..
In North Carolina, where soybeans and corn are the two primary crops, the recent increase in the demand for U.S. corn has triggered a shift of farm acreage from soybeans to corn, leading to a rapid rise in prices of both commodities. However, the rate of the price changes, as well as the price level, is significantly different in markets that are located in different parts of the state. This study extends the literature that examines linkages between spatially separated markets by using a threshold autoregressive model with a less restrictive assumption for estimating the transaction cost neutral band -- the band within which trade is not profitable. This generalization allows the neutral band of transactions costs to change according to various external...
