Coupon Impacts on Orange Juice Demand Based on Time-Series and Cross-Sectional Data AgEcon
Brown, Mark G..
A recent study by Dong and Leibtag found coupons were effective in increasing fruit and vegetable demand. The current study supports these finding for the OJ product group. The analysis focused on the informational/advertising or demand shift impact of coupons, as opposed to the price impact which could not be determined since data on prices were a weighted average for coupon users and non-users. The results indicate a 6% increase in OJ gallons sales when coupons are used. The coupon variable used in the analysis, however, measures the extent of coupon usage but not intensity. As such, the results provide a partial view of the impact of coupons and further analysis on data that also includes some measure of intensity is needed to more fully evaluate...

RESTRICTIONS ON THE EFFECTS OF PREFERENCE VARIABLES IN THE ROTTERDAM MODEL AgEcon
Brown, Mark G.; Lee, Jonq-Ying.
This study examines imposing and testing restrictions on preference variables in the Rotterdam model through the impacts of these variables on marginal utilities. An empirical analysis of the impact of a female labor force participation variable in a Rotterdam demand system for fresh fruit illustrates the methodology. This variable was modeled through its impact on marginal utilities via "adjusted" prices, following theoretical work by Basmann and Barten, among others. Results show that the female labor participation has negatively impacted the demands for citrus, while positively impacting the demands for other fresh fruit.

Public Policies and the Demand for Vegetables AgEcon
Gustavsen, Geir Waehler; Rickertsen, Kyrre.
Increased consumption of vegetables may reduce obesity and the prevalence of cardiac diseases and cancer. Norwegians consume less vegetables than nutrition experts recommend and the per capita consumption is lower than in most European countries. To investigate the causes of low consumption, a two-step approach is used to estimate the demand segmented by nine different household types. In the first step, a probit model is estimated to investigate the decision whether to purchase traditional vegetables, salad vegetables, and industrially processed vegetables. Conditional on purchase, an almost ideal demand model is used to model how much to purchase. The own-price elasticities and total expenditure elasticities are high for traditional and industrially...

The Estimation of Food Demand Elasticities in Canada AgEcon
Pomboza, Ruth; Mbaga, Msafiri Daudi.
Changing consumer and market demands is an important driver behind the challenges and opportunities that are facing the agriculture and agri-food sector in Canada and that will influence the sector's profitability and competitiveness in the future. It is therefore important to understand developments in the consumer demand for agriculture and agri-food products. The report provides updated demand elasticities for fourteen food groups in Canada. The estimates are useful for conducting analysis of the changing structure of the agriculture and agri-food sector and can help quantify the impacts that changes in economic variables and policies that impact those economic variables might have.

Obesity and Nutrient Consumption: A Rational Addiction? AgEcon
Richards, Timothy J.; Patterson, Paul M.; Tegene, Abebayehu.
Widespread obesity in the U.S. is a relatively recent phenomenon, reaching epidemic proportions only in the last 15 years. However, existing research shows that while calorie expenditure through physical activity has not changed appreciably since 1980, calorie consumption has risen dramatically. Consequently, any explanation of obesity must address the reason why consumers tend to overeat in spite of somewhat obvious future health implications. This study tests for an addiction to food nutrients as a potential explanation for the obesity epidemic. Specifically, we use a random coefficients (mixed) logit model applied to household scanner data to test a multivariate version of the rational addiction model of Becker and Murphy and Chaloupka. We find evidence...

TESTING AGGREGATION WITHOUT SEPARABILITY IN MEAT DEMAND: AN INVESTIGATION OF THE GENERALIZED COMPOSITE COMMODITY THEOREM AgEcon
Davis, George C..
In the estimation of aggregate meat demand systems, weak separability is often a maintained assumption. However, only a few studies have tested and failed to reject this assumption. Recently, Lewbel (1996) developed a generalized composite commodity theorem (GCCT) that is less restrictive than weak separability. In this study, a data set in which the weak separability conditions for aggregation have been rejected is reconsidered to determine if aggregation can be based on the GCCT. Some subtleties of Lewbel's testing procedure that are not discussed by Lewbel are considered, and the fundamental problem of formulating aggregates prior to conducting tests for aggregation is addressed.

An Assessment of Dynamic Behavior in the U.S. Catfish Market: An Application of the Generalized Dynamic Rotterdam Model AgEcon
Muhammad, Andrew; Jones, Keithly G..
The generalized dynamic Rotterdam model was used in estimating U.S. demand for disaggregated catfish. The overall goal was to examine habit persistence in consumption and to determine the adjustment process in demand. Results indicated that it took up to 1 month for catfish-product demand to fully adjust to changes in expenditures and prices. Additionally, habit persistence played a role in demand where present consumption of a given product was positively affected by past consumption of that product. Consequently, U.S. catfish demand was significantly more elastic in the long-run.

Factors Influencing Demand for a Producer-Owned Beef Retail Outlet AgEcon
Lusk, Jayson L.; Cevallos, Edgar.
As the farm-to-retail price spread continues to grow, come cattle producers a beginning to consider integrating into the retail sector. Such a venture would require large investments in capital with uncertain return. This study seeks to determine the potential success of a stand-alone retail outlet selling “all natural” beef in an affluent area of Jackson, MS. Using choice-based conjoint analysis, demand for the new retail outlet is modeled as a function of the beef price at the store, distance of the store from consumers’ homes, distance of the store from consumers’ typical grocery store, and price of beef at substitute grocery stores. Simulation results suggest the proposed outlet could be a profitable venture, depending upon location and beef price.

U.S. Honey Supply Chain: Structural Change, Promotions and the China Connection AgEcon
Ward, Ronald W.; Boynton, Bruce.
Honey is a by‐product of the pollination of plants and essential to almost all agricultural plant product. Demand for honey provides a partial compensation for the pollination services. Hence, programs to support honey demand such as promotions are potentially very important to the agricultural sector as well as the honey industry. Honey is utilized for table consumption and for manufacturing and both U.S. domestic and foreign honey imports both contribute to the U.S. honey availability. Econometric models are estimated showing the domestic table‐use and manufacturing demand with the models explicitly incorporating the effects of generic promotion of honey. Rates-of‐ return to the U.S. honey promotion programs are estimated with rates assigned to domestic...

Key Issues Affecting the Feasibility of Producer-Owned, Value-Added Ventures in the South AgEcon
Wolfe, Kent; Barefield, Alan.
The transition from agricultural producer to agribusiness entrepreneur is littered with obstacles not associated with traditional farming operations. Producers are typically faced with an established market for their products as well as defined production practices and budgets. These familiar industry institutions are not available for use in the agribusiness environment. As a result, entrepreneurs are faced with new, unfamiliar situations that can significantly affect the success of their proposed or fledging business.

Home Bias in U.S. Beer Consumption AgEcon
Lopez, Rigoberto A.; Matschke, Xenia.
We apply the Berry, Levinsohn and Pakes (1995) market equilibrium model (BLP) to data from 30 brands of beers sold in 12 U.S. cities over 20 quarters (1988-92) to estimate the consumers’ taste for beer characteristics (price, alcohol content, and calories) as well as for the cultural region of origin (USA, Anglo-European, Germanic, and countries bordering the U.S.). Consumer heterogeneity is allowed with respect to age, income and gender. Overall we end up with 7,200 beer brand observations (30x12x20) and 13,920 (58 random draws x 12 x 20) consumer observations. Empirical results indicate that indeed there is home bias with respect to European beers and somewhat less so with respect to beers from bordering countries (Mexico and Canada). Home bias is more...

ESTIMATIVA DA DEMANDA DE ÁGUA RESIDENCIAL URBANA NO ESTADO DO CEARÁ AgEcon
Fontenele, Raimundo Eduardo Silveira; Rosa, Antonio Lisboa Teles da; Nogueira, Claudio Andre Gondim.
This study determined a function demand for residential water. The data were stratified by geographic areas according to the level of regularity of water supply to the households. Income, price, number of rooms and persons in the households were found to be the main variables influencing the level of water consumption. Differences between: i) households connected to the water and sewage systems and those connected only to the water system; ii) households with up to 20 m3 of water consumption and those with consumption between 20 and 50 m3 and finally those with consumption above 50 m3 were surveyed. The results of the residential water demand were, in general, statistically significant and the coefficients presented the expected sign. These results are...

Buyer and Seller Response to an Adverse Food Safety Event: The Case of Frozen Salmon in Alberta AgEcon
Maynard, Leigh J.; Saghaian, Sayed H.; Nickoloff, Megan.
Fish is a low-fat protein source high in omega-3 fatty acids, but in 2004 consumers also heard that farmed salmon had high levels of polychlorinated biphenyl (PCBs). This research evaluated how Canadian consumers and processors reacted to the conflicting health messages. Demand estimates and time-series analysis of 2001-2006 frozen meat scanner data in Alberta, Canada show a significant drop in salmon expenditure share following the PCB finding. The industry responded by launching low-priced wild salmon products, which contributed to significant demand expansion. The analysis illustrates how a food safety threat was averted and even served as a catalyst for growth.

UNDERSTANDING THE DEMAND SIDE AND COORDINATING THE SUPPLY SIDE FOR CONNECTED GOODS AND SERVICES AgEcon
Ladegard, Gro; Romstad, Eirik.
This paper addresses the coordination and innovation issues needed for promoting value added at the rural and regional level. There are two sides to value added: the ability to meet consumer demand, and to identify least cost ways of supplying the demanded goods. Human and social capital plays an important role on both sides. At the municipality level the supply side issues are complex. First, because the production space has far more dimensions than for the single entrepreneur. Second, because the value of some goods and services produced depend on what other goods and services that is available. On the supply side networks are important to solve the coordination issues, while networks for identifying and understanding consumer preferences are important...

DEMAND FOR MEAT AND FISH PRODUCTS IN KOREA AgEcon
Jung, Jione; Koo, Won W..
The Korean livestock industry is currently facing the critical challenge of the market liberalization trend under the World Trade Organization. This study analyzes the consumption behavior of meat and fish products in Korea, by estimating the Linear Approximate Almost Ideal Demand System (LA/AIDS). The empirical results indicate that beef imports in Korea would increase in the future under trade liberalization. If cheap and better quality imported beef are introduced to Korean consumers, Hanwoo (Korean domestic cattle) beef would not maintain its market share. Key words: Meat, fish, trade liberalization, per capita consumption, demand, separability, and price elasticity.

European Demand for Orange Juice AgEcon
Brown, Mark G..
The demand for OJ in Europe, and in particular the own-price elasticity of demand, has been difficult to estimate due to lack of good data. Europe, however, is the largest OJ market in the world (USDA, Foreign Agricultural Service), and cannot be ignored in analyzing the U.S. and Florida OJ situations, given OJ is an internationally traded commodity. Thus, estimates of the impacts of factors such as own-price on Europe’s OJ demand are critical for understanding the market. The estimates in this study, although rough, provide some guidance for the magnitude of the price response in Europe, but to keep them in perspective, they are based on a relatively small number of observations and a proxy variable, suggesting that, as more and hopefully better data...
