A DOUBLE-HURDLE MODEL OF FOOD DEMAND WITH ENDOGENOUS UNIT VALUES AgEcon
Dong, Diansheng; Gould, Brian W..
This study develops a unique double-hurdle model of demand for composite food commodities which endogenizes unit values. The model structure allows us to account for the inability to observe such values for non-purchasing households and simultaneously adjusts for quality demand effects reflected in these unit values. Application to Mexican household food expenditure data shows the importance of controlling for the quality of composite goods. We find that poultry and pork expenditures depend on both quantity demanded and quality desired.

A MODEL OF HOUSEHOLD TYPE SPECIFIC FOOD DEMAND BEHAVIOUR IN HUNGARY AgEcon
Brosig, Stephan.
The paper describes a two stage model of Hungarian households'’ food demand. Demand for the food aggregate is represented by a Working-Leser type single equation model while demand for seven distinct food types is modelled in a complete demand system using the LA/AIDS functional form. Estimation is based on household budget survey data for 1996. Demand elasticities are estimated for average households as well as for specific groups defined by sociodemographic characteristics. Fruit and vegetables are found to be the food types with most elastic demand but in general, differences between elasticities for different products as well as between different sociodemographic groups are relatively small.

Accounting for Product Substitution in the Analysis of Food Taxes Targeting Obesity AgEcon
Miao, Zhen; Beghin, John C.; Jensen, Helen H..
We extend the existing literature on food taxes targeting obesity. First, we incorporate the implicit substitution between sugar and fat nutrients implied by a complete food demand system and by conditioning on how food taxes affect total calorie intake. Second, we propose a methodology that accounts for the ability of consumers to substitute leaner low-fat and low-sugar items for rich food items within the same food group. This substitution is integrated into a demand system in addition to substitution among food groups. Simulations of a tax on added sugars show that the impact of the tax on consumption patterns is understated and the effect on welfare loss overstated when abstracting from this substitution within food groups.

Agricultural Research for Development in the Tropics: Caught between Energy Demands and Food Needs JARTS
Asch, Folkard; Huelsebusch, Christian.
We have shown in this analysis, that there is no easy answer to the question: is biofuel out competing food production for natural resources. We feel that when addressing this issue future discussions need to include a broader view on the global consequences of regional and national actions. It is necessary to base decisions not on short-term political or economic arguments but on the long term balance for resources and environmental health, both providing the basis for the livelihood of future generations. Therefore, efforts must be made to calculate the real carbon balance and water foot prints for every item and process involved in the production chains and base decisions on the least detrimental approach to crop and energy production and not on the...

Analyzing the Impact of Food Safety Information on Food Demand in China AgEcon
He, Dehua; Chidmi, Benaissa; Zhou, Deyi.
This study analyzed the impact of food safety information on food demand in urban China. The LA/AIDS model was estimated by using national province level food consumption data and quantities of articles about food safety event on public media from 2000 to 2008. The results of the study show that urban Chinese consumer food demand was influenced by food safety information from daily newspapers and GM labeling policy. This paper also indicates food price elasticities, expenditure elasticities by categories and the effect of food safety information.

Caught between Energy Demands and Food Needs: Dilemmas of Smallholder Farmers in Njoro, Kenya JARTS
Ngetich, K. A.; Birech, R. J.; Kyalo, D.; Bett, K. E.; Freyer, B..
Smallholders in rural Kenya, like their counterparts in tropical Africa currently face acute shortage of fuel wood for domestic use. There has been rapid population increase in the last few decades resulting in increased demand for food crops. This has led to the expansion of area under subsistence agriculture eating into indigenous forests, the traditional source of wood fuel. This situation has been compounded by the limited access to alternative sources of domestic energy in rural parts of Kenya. The recent upsurge in the cost of fossil-derived fuels as well as in hydro-generated electricity has left the smallholder farmer with wood as the sole source of fuel. This paper therefore examines the conflicting demands of domestic fuel needs and foods. Key...

CHINESE CONSUMER DEMAND FOR ANIMAL PRODUCTS AND IMPLICATIONS FOR U.S. PORK AND POULTRY EXPORTS AgEcon
Wang, Qingbin; Fuller, Frank H.; Hayes, Dermot J.; Halbrendt, Catherine K..
This paper examines Chinese consumer preference for major animal products and assesses the potential impacts of a reduction in China's import tariff on its pork and poultry demand and net import. Our analysis suggests that China's demand for animal products will continue to grow as income increases. Using a trade model, results of our scenario analysis indicate that a reduction in China's import tariffs will significantly increase its net pork and poultry imports and the U.S. will capture most of the increases. Nevertheless, the impact on the market price in China and the U.S. is likely to be very small.

Cross-Price Elasticities of Demand Across 114 Countries AgEcon
Regmi, Anita; Seale, James L., Jr..
This report presents a simple methodology for calculating cross-price elasticities across countries, using the Frisch own-price elasticity. Cross-price elasticities are calculated for 9 major consumption categories from the 1996 International Comparison Program data across 114 countries. The consumption categories are: food, beverage, and tobacco; clothing and footwear; education; gross rent, fuel, and power; house furnishings and operations; medical care; recreation; transport and communications; and “other” items. Additionally, cross-price elasticities are calculated and reported for a two-good demand system of food and nonfood. The elasticity estimates from this report are the only available consistent cross-country cross-price elasticity estimates...

DETERMINANTS OF FOOD AWAY FROM HOME AMONG AFRICAN-AMERICANS AgEcon
Pert, Calvert; Bhuyan, Sanjib.
The prominence of FAFH on consumers’ food expenditure raises some important questions, particularly those related to the health impact of such a trend. This is particularly true among African-Americans because on average African Americans are twice as likely as white Americans to develop Type 2 diabetes, which has been known to have some correlation with one’s diet. There is a plethora of studies focusing on FAFH by American consumers. However, there are very few studies that focus exclusively on African-Americans. This study tries to fill that gap.

Determinants of Meats Purchase Behavior by Ethnic Groups AgEcon
Garcia-Jimenez, Carlos I.; Mishra, Ashok K..
Farmers and food companies need to assess their production and marketing strategies for nurturing business opportunities that will arise from the simultaneous increase in population and income of Hispanics in the United States. Previous studies on demand for meat products have not received much attention on the determinants of meats purchase behavior by Hispanics in relation to other ethnic groups. This study investigates the impact of ethnicity and the determinants of meats purchase behavior in the U.S. by using single Probit equations. The analyzed data comes from the U.S. Consumer Expenditure Survey. The results indicate that ethnicity plays an important role in the purchase behavior of meat products, as well as household size and income.

Does Measurement Error Explain a Paradox About Household Size and Food Demand? Evidence from Variation in Household Survey Methods AgEcon
Gibson, John.
Several recent papers report a puzzling pattern of food demand falling as household size rises at constant per capita expenditure, especially in poorer countries. This pattern is contrary to a widely used model of scale economics. This paper exploits within-country differences in household survey methods and interviewer practices to provide a measurement error interpretation of this puzzle. A comparison of household surveys in Cambodia and Indonesia with the results from Monte Carlo experiments suggest that food expenditure estimates from shorter, less detailed recall surveys have measurement errors that are correlated with household size. These correlated measurement errors contribute to the negative effect of household size on food demand and cause...

Elastizitäten der Nachfrage privater Haushalte nach Nahrungsmitteln – Schätzung eines AIDS auf Basis der Einkommens- und Verbrauchsstichprobe 2003 AgEcon
Thiele, Silke.
This paper presents price and income elasticities of food demand in Germany. Using cross sectional data from the 2003 German income and consumption survey a Linear Approximate Almost Ideal Demand System is employed. Two aspects which have to be taken into account when using cross-sectional data are insufficient price information and zero expenditures. An approach of COX and WOHLGENANT (1986) is applied to derive quality adjusted prices. In order to take into account censoring of the dependent variables a procedure of SHONKWILER and YEN (1999) was employed. A high expenditure elasticity is found for meat demand. The highest own-price elasticities are for the demand for meat/-products and milk/-products. Within the meat group, beef demand shows a particular...

Estimation of Demand Elasticity for Food Commodities in India AgEcon
Kumar, Praduman; Kumar, Anjani; Parappurathu, Shinoj; Raju, S.S..
The food demand in India has been examined in the context of a structural shift in the dietary pattern of its population. The results have reinforced the hypothesis of a significant diversification in the dietary pattern of households in recent years and has found stark differences in the consumption pattern across different income quartiles. The food demand behaviour has been explained using a set of demand elasticities corresponding to major food commodities. The demand elasticities have been estimated using multi-stage budgeting with QUAIDS model and another alternative model, FCDS. The study has revealed that the estimated income elasticities vary across income classes and are lowest for cereals group and highest for horticultural and livestock...

Food Demand Analysis of Indonesian Households with Particular Attention to the Poorest AgEcon
Pangaribowo, Evita Hanie; Tsegai, Daniel W..
The purpose of this study is to analyze the demand responses of Indonesian households to food prices, income changes and other socioeconomic factors. The underlying assumption here is that inadequate information on household food expenditure patterns which vary across income groups and regions may have its contribution to the persistence of food insecurity. We use the Indonesian Family Life Survey data and methodologically we employ an extended form of the Quadratic Almost Ideal Demand System model which includes demographic and regional factors. Results reveal the well known pattern that food demand behavior varies significantly between urban and rural households as well as income groups. The poorest households consume relatively more staple food as well...

FORCES RESHAPING WORLD AGRICULTURE AgEcon
Mattson, Jeremy W.; Koo, Won W..
This paper examines many of the forces reshaping world agriculture. Among these forces are increased trade liberalization, agricultural research and development, and new movements in developing countries. Worldwide agricultural production is likely to become more competitive as a result of increased trade liberalization through the World Trade Organization and regional and bilateral free trade agreements. Countries can become more competitive through agricultural research and development. As a result of research and development, total agricultural production has increased significantly across the world over the last several decades. Agricultural research has also led to the development of many new, non-food uses for agricultural products. New...

Fragmenting markets and quality change in New Zealand foods: empirical analysis with a Rotterdam model AgEcon
Khaled, Mohammed; McWha, Vhari; Lattimore, Ralph G..
Very little is known about changes in the demand characteristics of food in New Zealand. As far as we can determine, there has never been a complete disaggregated food demand model estimated for New Zealand. The object of this paper is to update these estimates using more recent data to see whether there are grounds for believing that the structural changes that occurred primarily during the last two decades are having effects on the magnitude of food demand elasticities in New Zealand. To this end, a Rotterdam food demand system is estimated using time series data. The results indicate that over the last 20 years, household consumption has increased for fruit and vegetables, poultry, food eaten away from home, and sweet products, drinks and other foods....
