Wheat / Flour Price Transmission and Agricultural Policies in Ukraine: A Markov-Switching Vector Error Correction Approach AgEcon
Brümmer, Bernhard; Zorya, Sergiy.
The analysis of price transmission between raw and processed agricultural products in transition countries is complicated by the frequently changing conditions on their way from plan to market. We utilise a Markov-switching vector error correction model to allow for multiple regime shifts in the price relationship between wheat and wheat flour in Ukraine from June 2000 to November 2004. The analysis reveals four regimes. The observed temporal pattern of these regimes can be matched with certain political and economic events in Ukraine. In particular, we find a strong link between the 'high uncertainty' regime and discretionary policy interventions in 2003.

Do rBST-Free and Organic Milk Stigmatize Conventionally Produced Milk? AgEcon
Kanter, Christopher; Messer, Kent D.; Kaiser, Harry M..
Producers are continually seeking to differentiate their products in the marketplace. A common approach is via labeling where differences in production methods are marketed. Yet, positive labeling for the new product has the potential to stigmatize the conventionally produced product by highlighting perceived problems with the product. The net economic result can be negative to producers as the conventional product that dominates the market is stigmatized by the new product that has little market share, and this leads to consumers decreasing their willingness to pay for the conventional product. This experimental research identifies this stigma effect in the case of milk, where the presentation of rBST-Free milk reduces consumers' willingness to purchase...

CHARACTERISTICS OF CONSUMERS DEMANDING AND THEIR WILLINGNESS TO PAY FOR CERTIFIED SAFER PORK AgEcon
Miller, Gay Y.; Unnevehr, Laurian J..
A telephone survey of 609 Illinois households was conducted in spring 1999. Most consumers surveyed have concerns about pork safety. Concerns were greatest among households with children, lower incomes, older consumers, and Blacks. Lower consumption of pork was associated with higher concern. Consumers had more confidence in USDA certification of enhanced pork safety than in industry certification. Most consumers were willing to pay some price premium for a certified safer product. Those willing to pay more were more likely women, older consumers with incomes less than $70,000, who live in an urban household, and have concern about pork safety.

TWO-STAGE UTILITY MAXIMIZATION AND IMPORT DEMAND SYSTEMS REVISITED: LIMITATIONS AND AN ALTERNATIVE AgEcon
Davis, George C.; Jensen, Kimberly L..
Two-stage utility maximization theory has been widely used in the literature to estimate import demand for agricultural commodities that are often inputs. This article examines the overlooked conceptual and empirical limitations of applying two-stage utility maximization theory to model the demand for imported commodities that are inputs. A discussion is presented about how the underutilized theory of two-stage profit maximization overcomes these limitations. Also discussed are the conditions under which errors illustration of the two-stage profit maximization procedure is provided.

Effects of Price and Quality Differences in Source Differentiated Beef on Market Demand AgEcon
Lee, Young-Jae; Kennedy, P. Lynn.
In order to estimate demand elasticities of source differentiated beef in South Korea, this study used the quantity of an endogenous demand system derived through maximizing the economic welfare of market participants including local beef consumers and local and foreign beef suppliers. The demand system is then weighted with respect to quality adjustment parameters to identify the effects of quality differences in source differentiated beef on market demand. As implied by the high relative price of locally produced ‘‘Hanwoo’’ beef, substitutability between local and imported beef is shown to be very weak and the own price elasticity of South Korean beef is shown to be inelastic. Related to quality differences between source differentiated beef, South...

Geographic Differences in the Relative Price of Healthy Foods AgEcon
Todd, Jessica E.; Leibtag, Ephraim S.; Penberthy, Corttney.
Although healthy foods can be affordable, if less healthy foods are cheaper, individuals may have an economic incentive to consume a less healthful diet. Using the Quarterly Food-at-Home Price Database, we explore whether a select set of healthy foods (whole grains, dark green vegetables, orange vegetables, whole fruit, skim and 1% milk, fruit juice, and bottled water) are more expensive than less healthy alternatives. We find that not all healthy foods are more expensive than less healthy alternatives; skim and 1% milk are less expensive than whole and 2% milk and bottled water is generally less expensive than carbonated nonalcoholic drinks. We also find considerable geographic variation in the relative price of healthy foods. This price variation may...

DEMAND FOR NUTRIENTS: THE HOUSEHOLD PRODUCTION APPROACH AgEcon
Chung, Rebecca H.; Lee, Jonq-Ying; Moss, Charles B.; Brown, Mark G..
The household production approach is used to characterize the household's preference toward nutrients in food consumption. Elasticities of substitution and Hicksian price elasticities are estimated, price- and expenditure-nutrient elasticities are calculated. Results show that protein is the most expensive nutrient, and that nutrients played an important role in determining households' food consumption.

Estimation of a Censored AIDS Model: A Simulated Amemiya-Tobin Approach AgEcon
Dong, Diansheng; Kaiser, Harry M..
Kuhn-Tucker approach and its dual have been proposed to the demand system estimation when there are non-negativity bindings. However, empirical researchers have been struggling two decades in applying this method into practice due to: (1) the difficulty in derivation of a coherent econometric model, and (2) the cumbersome evaluation of high order probability integrals needed in parameter estimation. In this paper, we avoid the above two issues by using the Amemiya-Tobin demand system approach and the simulation procedure to evaluate the probability integrals. An AIDS model is estimated and the elasticities are obtained that are impossible to achieve when using Kuhn-Tucker approach. The model is applied to an analysis of Canadian household food demand.

A partial analysis of the fruit and vegetable sector in Austria AgEcon
Hambrusch, Josef; Quendler, Erika.
With respect to the new Common Market Organisation (CMO) for fruit and vegetables, the present paper focuses on societal developments that influence the demand for fruits and vegetables, provides some basic information on fruit and vegetable production in Austria and, finally, describes the roles of Producer Organisations (PO) and retailers in Austria. The study is based on a literature review as well as on interviews with representatives of the POs. The results reveal that six Austrian POs face an increasing concentration process in the Austrian retail industry, which is important since roughly 90% of all fruits and vegetables are distributed in retail and discount outlets. Furthermore, during the last ten years the overall consumption of fruits and...

Effects of Increased Biofuel Blending on Demand for Biomass, Food Production and Commodity Prices in Eastern Germany AgEcon
Zeller, Heiko; Haring, Anna Maria; Khachatryan, Armen.
Renewable resources are gaining importance in modern society due to their expected positive effects on agriculture, the environment and the economy. To support renewable energy from biomass the EU promotes the cultivation of energy crops. A spatial equilibrium model is applied based on the concept of maximizing net welfare, to provide information whether energy crop production competes with food production for land area and to show the effects of increased biofuel demand on food prices. The Model of Interregional Trade of Energy Crops (ITEC) refers to Eastern Germany and adjacent areas of Poland. Results show that the regions produce enough feedstocks to meet the demand for food and biofuel production. In many cases both food crops and biofuels are either...

DERIVED DEMAND ELASTICITIES: MARKETING MARGIN METHODS VERSUS AN INVERSE DEMAND MODEL FOR CHOICE BEEF AgEcon
Marsh, John M..
Three methods of calculating the derived elasticity of demand for Choice slaughter beef are used: (a) a traditional marketing margin approach, (b) a modified marketing margin approach, and (c) an econometric, inverse demand model approach. The first method is more restrictive than the second but both tend to overestimate beef price flexibility and revenue changes. The econometric model, though an incomplete demand system, yields demand elasticities that are more consistent with marketing flexibility but are less pronounced than estimates of a complete system. An example using a two-year revenue forecast compares slaughter revenue adjustments based on the first margin method with those based on structural demand models.

Agricultural Profits and Farm Household Wealth: A Farm-level Analysis Using Repeated Cross Sections AgEcon
Blank, Steven C.; Erickson, Kenneth W.; Nehring, Richard F.; Hallahan, Charles B..
This study examines the relationship between agricultural profits and farm household wealth across locations and farm sizes in U.S. agriculture. A multiperiod household model is used to develop hypotheses for testing. Results indicate that farmland has out-performed nonfarm investments over the past decade. Thus, households may want to keep their farmland to build wealth, even if it requires them to earn off-farm income. The analysis implies that decision will be made based on farm household wealth factors having little to do with agriculture.

Comparing Parts with the Whole: Willingness to Pay for Pesticide-Free, Non-GM, and Organic Potatoes and Sweet Corn AgEcon
Bernard, John C.; Bernard, Daria J..
Auction experiments were used to investigate demand relationships and willingness to pay (WTP) for four versions of potatoes and sweet corn—conventional, organic, and two parts of organic: no pesticides and non-genetically modified (non-GM). Elasticities showed strong and asymmetric substitute relationships between organic and its parts. Combined premiums of the parts were not significantly different than the whole organic premium, suggesting WTP for the attributes are not additive. A two-stage heteroskedastic tobit model found significant WTP for each part dependent on demographics and beliefs about conventional versions. Results suggest segments for parts of organic could be established alongside the whole.

Expert opinion and cuisine reputation in the market for restaurant meals AgEcon
Fogarty, James Joseph.
As food is an experience good, the market for restaurant meals is a market where the cost of acquiring information regarding quality is relatively high. In such markets consumers often turn to reputation measures to guide purchase decisions. As Australia does not have a longstanding cuisine style of its own, and given Australia has been open to substantial immigration inflows since federation, it represents an especially appropriate market to study regarding the impact of individual restaurant reputation and collective cuisine reputation on meal prices. The following study uses the hedonic price approach to investigate the implicit price of individual reputation indicators, cuisine type reputation indicators, and other objective indicators in the market...

Price Discovery and Pricing Choice Under Divergent Supply Scenarios in an Experimental Market for Fed Cattle AgEcon
Ward, Clement E..
Previous research has not addressed the impacts of alternative supply conditions on price discovery and pricing choice. This study estimated models with data from an experimental market, the Fed Cattle Market Simulator, encompassing live weight, dressed weight, and grid pricing under two alternative supply scenarios. Significance of variables explaining transaction price variation and pricing choice differed between the two supply periods. Overall results were close to expectations. Higher quality cattle marketed with a grid brought higher prices in both supply periods. Having lower quality cattle in either supply period increased the probability of cattle being marketed (purchased) on a live weight basis.
