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 ones 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.

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....

Accounting for Product Substitution in the Analysis of Food Taxes Targeting Obesity

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.

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...

Does Measurement Error Explain a Paradox About Household Size and Food Demand? Evidence from Variation in Household Survey Methods

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...

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...

This paper examines the relationship of 1987 retail grocery prices to supermarket sales concentration across 95 U.S. metropolitan areas. The regression model incorporates a large number of population, retail-cost, and retail competition factors and separate prices by type of grocery item. We find that the concentration-price relationship is sensitive to item type: positive for packaged, branded, dry groceries and unrelated for produce, meat, and dairy product prices. As for market rivalry, we find that small grocery stores provide no grocery price competition for supermarkets. However, branded grocery prices are driven down by fast-food places and by rapid price churning, whereas for unbranded foods the presence of warehouse stores places downward...

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...

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.

A great deal of research on farm and food policy and consumer choice focuses on the link between food consumption and nutrition. This paper presents and applies a new method to analyze the demand for food and nutrients, and consumer welfare. The foundation for this method is the recent extension of the Gorman class of exactly aggregable demand models to incomplete demand systems. The purposes of this approach are to derive and implement coherent, flexible empirical models of food and nutrient demand, to estimate the model parameters consistently with aggregate data, and to make inferences on the impacts of farm and food policy changes on food and nutrient demand and consumer welfare of those policies. We apply this framework to annual per capita U.S....

Food expenditure patterns were examined for Hispanic households in the U.S. Engel curves for three food categories: food eaten at-home, food eaten away-from-home, and for total food, were estimated using four different functional forms. Confidence intervals for income and household elasticities were computed and results compared with previous research.

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.

Projections of world food demands hinge critically on the underlying functional form used to predict future demands. Simple functional forms can lead to unrealistic projections by failing to capture changes in income elasticities of demand as consumer becomes wealthier. This paper compares several demand systems in the projection of disaggregated food demand across a wide range of countries with different income levels using a global general equilibrium model. We find that the recently introduced AIDADS system represents a substantial improvement over existing demand systems currently in use in CGE modeling. In particular, our projection results show that for relatively poor regions experiencing rapid income growth, the widely used LES and CDE demand...

Elastizitäten der Nachfrage privater Haushalte nach Nahrungsmitteln – Schätzung eines AIDS auf Basis der Einkommens- und Verbrauchsstichprobe 2003

Gibson, John.

Rapid urbanization is a major cause of structural change in food demand. In West Africa, urbanization is associated with a switch from coarse grains to rice and wheat, in Melanesia the switch is from root crops to rice and wheat, while in much of Asia the switch is away from cereals (and within cereals to wheat). Although reasons why urban diets differ from traditional rural diets are well known, the rate at which recent arrivals from the countryside switch their diet has not been estimated. Evidence on the speed of this dietary change can help to show whether studies of urban food demand need to control for cohort effects and may also help producers forecast the size of their future urban markets. This paper uses cross-sectional household survey data from...

Lithuania's Food Demand During Economic Transition

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...

The linear approximate version of the AIDS model is estimated using data from the Lithuanian household budget survey covering the period from July 1992 to December 1994. Price and real expenditure elasticities for twelve food groups were estimated based on the estimated coefficients of the model. Very little or nothing is known about the demand parameters of Lithuania and other former socialist countries, so the results are of intrinsic interest. Estimated expenditure elasticities were positive and statistically significant for all food groups while all own-price elasticities were negative and statistically significant, except for that of eggs which was insignificant. Results suggest that Lithuanian household consumption did respond to price and real...
