Advertising Expenditures and the Consumption of Alcoholic Beverages

The theory of consumer behavior is applied to the estimation of a demand svstem. Monthly data on alcoholic beverages (beer, wine, liquor, soft dhnks) from the province of Ontario in Canada are analyzed. Before estimating the linear approximate almost ideal demand system (LA/AIDS), unit root and cointegration tests are implemented. Budget shares, per capita advertising expenditures, real total expenditure, prices and per capita consumption are found to be non-stationary. The budget share, the advertising expenditures, the prices and the real total expenditure are cointegrated for each beverage. Own and cross-price elasticities, income elasticities and own and cross-advertising elasticities are calculated from the estimated or the demand system. Based on own-price elasticities and income elasticities, alcohol consumption is consistent with the law of demand and the products analyzed are normal goods. The estimation of income and advertising effects is important for analyzing the need for, and the effectiveness of, potential control policies. The advertising elasticities are small but statistically significant. This suggests that advertising may promote alcoholic beverage consumption. The estimated inelastic demands for beer and wine suggest that the primary purpose of high excise taxes levied by the Federal and Provincial governments is to raise government revenues and not to discourage consumption.     

Modeling the demand for alcoholic beverages and advertising specifications

In this paper, the demand for beer, wine, spirits and soft drinks in Ontario is modeled in two parts: an equation is specifiec to endogenize group expenditures and a demand system is set up to allocate budgeted group expenditures across types o beverages. Advertising is allowed to influence both the level of group expenditures and its allocation. Three popula advertising specifications are compared using theJ‐test and the likelihood dominance criterion. Even though all threi specifications fitted well according to standard criteria, the calculated expenditure, price and advertising elasticities wen sensitive to the manner with which advertising is specified. This clearly highlights the need to rely on a sound criterion t< identify a dominant specification. From the identified dominant specification, we found that advertising has very subtle effect on expenditures on alcoholic beverages (group and individual beverages). Thus, advertising is not effective in enlarginj markets and this suggests that firms (especially breweries) use advertising to compete in zero‐sum market share games. From i public policy perspective, our results are comforting but future research should investigate whether the neutral effect o advertising on aggregated expenditures hide substantial offsetting changes in the drinking habits of individuals.     

Food demand elasticities for Australia

There is renewed interest in robust estimates of food demand elasticities at a disaggregated level not only to analyse the impact of changing food preferences on the agricultural sector, but also to establish the likely impact of pricing incentives on households. Using data drawn from two national Household Expenditure Surveys covering the periods 1998/1999 and 2003/2004, and adopting an Almost Ideal Demand System approach that addresses the zero observations problem, this paper estimates a food demand system for 15 food categories for Australia. The categories cover the standard food items that Australian households demand routinely. Own‐price, cross‐price and expenditure elasticity estimates of the Marshallian and Hicksian types have been derived for all categories. The parameter estimates obtained in this study represent the first integrated set of food demand elasticities based on a highly disaggregated food demand system for Australia, and all accord with economic intuition.     

A MODEL OF THE DISAGGREGATED DEMAND FOR MEAT IN AUSTRALIA

The focus of this study is the estimation of the Australian demand for meat between 1967 and 1990, employing a demand systems approach which uses the linear approximate, almost ideal demand system (LA/AIDS) model. Two demand systems are estimated by maximum likelihood methods, one for aggregate types of meat and one for disaggregated meat products. After correcting for serial correlation in the two demand systems, restrictions from utility theory are imposed and tested for their appropriateness. By using a new data set on the Australian retail price and consumption offresh pork, ham and bacon, the results from the disaggregated model provide the first estimates of the own-price, cross-price and expenditure elasticities for these commodities.     

A Meta‐Analysis on the Elasticity of Demand for Pesticides

There is an increasing policy interest in pesticide taxation schemes as a measure to reduce harmful effects of pesticide use. The effectiveness of such tax depends, however, on the price elasticity of demand for pesticides. Moreover, information on these demand elasticities and their determinants is of crucial relevance for policy‐making and normative modeling approaches. In this article, we present a meta‐analysis based on studies that have estimated pesticide demand elasticities in Europe and North America. Our meta‐analysis reveals that the own‐price elasticities of demand for pesticides are, with a median of ?0.28, significantly smaller than zero, but also significantly larger than ?1, i.e. to be inelastic. We find that the demand for pesticides for special crops is less elastic than that for arable and grassland. In addition, the demand for herbicides is more elastic than for other pesticides. Studies that consider only short‐term horizons and little flexibility for farmers to adjust to price changes generate significantly less elastic pesticide demands. The results also indicate that more recent studies identify lower pesticide price elasticities of demand. Furthermore, we find that peer‐reviewed studies tend to find more inelastic results compared to grey literature.     

Alcohol Tax,Price–Quality Proxy and Discounting: A Reason Why Alcohol Taxes May Rebound

The increasing concern about the external costs of alcohol consumption has often led economists and policy‐makers to advocate taxes to internalise the social costs and target consumption. However, in certain markets for alcoholic drinks – particularly wine – price is not only a cost but also an indicator of quality, guiding consumer choice. There is, perhaps, a higher probability of ex post satisfaction with products at higher prices in a market with potential adverse selection. The price–quality proxy interacts with discounts, where the full price of the product before discount (referred to as the External Reference Price in the marketing literature) is used as a quality reference. This study shows that an alcohol tax in the presence of discounting may increase the perceived value of the product, and therefore persuade consumers to prefer the purchase of more expensive wines with the highest discount. As a consequence, consumers could favour products with higher alcohol content – which contradicts the objectives of the policy. Consequently, for an alcohol tax to be effective discounting of alcoholic beverages (in particular, wine) should be regulated to avoid the policy backfiring.     

Consumer demand for diet quality: evidence from the healthy eating index

Few studies have been performed to use the detailed healthy eating index (HEI) to estimate consumer demand for diet quality. In this article, we apply household production theory to systematically estimate consumer demand for diet quality using the HEI developed by the U.S. Department of Agriculture. The results show that consumers have insufficient consumption of food containing dark green and orange vegetables, legumes and whole grains. Age and education have a significant impact on consumer demand for diet quality, but income does not. The own‐price elasticities of demand for diet quality are inelastic. Simulation of tax scenarios indicates that a tax on sugar‐sweetened beverage may be more efficient than a tax on fats, oils and salad dressing in improving consumer diet quality. This information is critical for policies and programs that are designed to improve healthy food choices, thereby reducing the social cost of public health.     

The demand for alcoholic beverages in Spain

The objective of this study is to analyze the main determinants of alcoholic beverages consumption at home. Data comes from the latest Spanish Household National Survey, which provides information on expenditure and quantities of different food products by household. Because households are interviewed only 1 week, a large number of zeros have been recorded. Among the existing censured demand models (the double hurdle (DH) model; the purchase‐infrequency model; and the Tobit purchase‐infrequency model, among others) and after carrying out model selection tests, the DH model has been finally estimated. All expenditure elasticities are positive, corresponding the highest value to spirits. Own price elasticities are negative and also in this case the spirits exhibit the highest value. Socio‐economic variables also play an important role in explaining consumer purchase and consumption decisions.     

THE ECONOMIC DETERMINANTS OF ALCOHOL CONSUMPTION*

In this paper is presented an analysis of the consumption patterns of beer, wine and spirits for Australia using data for the period 1955/56-1985/86. The validity of the demand theory hypotheses demand homogeneity and Slutsky symmetry has been tested using recently developed distribution? free procedures. The findings were that (i) beer and wine were necessities and spirits a strong luxury; (ii) beer and spirits are specific complements; and (iii) the homogeneity and symmetry hypotheses are acceptable. Preference for wine consumption seems to be independent of preference for beer and spirits.     

An Error Corrected Almost Ideal Demand System for Crustaceans in the United States

We have employed an error-corrected almost ideal demand system (ECAIDS) for major crustaceans at a disaggregated level in the United States. The proposed model can provide short- and long-run price elasticities. This article makes an important empirical contribution by reporting a set of reliable, policy-relevant estimates of the elasticities of demand for crustaceans in the United States. The habit formation behavior was significant only for crayfish. The value pricing strategy and the promotional pricing strategy are expected to benefit the domestic shrimp industry. Increasing prices through various marketing strategies can benefit domestic producers of lobsters and crabs.     

Imports versus Domestic Production: A Demand System Analysis of the U.S. Red Wine Market

The U.S. wine market experienced rapid growth in all facets—production, consumption, exports, and imports—over the past decade. Red wine imports more than tripled while consumption of domestically produced red wines doubled. This research estimates demand elasticities of U.S. red wine imports from five countries accounting for over 90% of imports—Italy, France, Spain, Australia, and Chile—using the first-difference version of the almost ideal demand system (AIDS). These elasticities are compared with those for domestically produced red wine. Results for conditional expenditure elasticities indicate that the U.S. red wine industry gains over imports when U.S. consumers' total expenditures on red wine increase. However, comparing own- and cross-price elasticities reveals an increase in the price of U.S. red wine results in a decline in quantity demanded six times greater than for French and Italian red wines and over 20 times greater than other import countries, thus harming the U.S. red wine industry. Empirical results suggest that U.S. red-wine producers could increase their total revenue by decreasing prices, while Italian and French producers can increase total revenues by increasing them.     

RURAL ASSISTANCE LEVELS: THE INFLUENCE OF POLICIES AND WORLD PRICE CHANGES

Two aspects of effective rates of assistance for Australian agricultural industries are examined. The long-term rate, rather than the rate for a single year, is determined and a rationale is sought for the pattern of assistance that emerges. Second, the influence of exogenous factors (as represented by changes in world prices) on assistance rates is examined. Assistance elasticities are calculated for the major agricultural commodities and estimates made of the likely change in the pattern of assistance rates from any general world price change. In addition, commodities with assistance rates potentially very different from existing rates are identified. Price transmission elasticities are also derived to indicate the degree of insulation that the various policies provide for each commodity.     

The demand for food and beverages in Norway

The demand for food and beverages is estimated within a three-stage demand model. The separability structure of the model is checked by nonparametric tests. Some generalized axiom of revealed preference (GARP) violations are detected in one of the subsystems. However, they are removed by small adjustments in the quantities of fish, and the violations are interpreted as results of measurement errors. The almost ideal demand system is used in the static and a dynamic version. The results of various specification and misspccification tests suggest that the static version performs poorly as compared with the dynamic version. Norwegian demand elasticities for disaggregate food commodities have rarely been estimated within a system framework, so the results are of intrinsic interest. The elasticities estimated by using the dynamic model are of the expected signs and reasonable magnitudes. The values are stable over time for most commodities. Elasticities estimated within a subsystem are conditional on the goods included in that system, and they may differ from the more policy relevant unconditional elasticities estimated within a system including all goods. Adjustment formulas are used to approximate the unconditional elasticities from the estimated conditional elasticities. There are considerable differences between the numerical values of the conditional and unconditional elasticities for several of the foods. The unconditional own-price elasticities are in the interval-0.20 to-0.89. The own-price elasticities for hot drinks and for milk are most inelastic. The unconditional expenditure elasticities for food-away-from-home, fish, soft drinks, and alcoholic beverages are above one, while the expenditure elasticity for hot drinks is about zero.     

Economic Growth,Globalisation and Beer Consumption

We analyse the evolution of beer consumption between countries and over time. Historically, there have been major changes in beer consumption in the world. In recent times, per capita consumption has decreased in traditional beer drinking countries while it increased strongly in emerging economies. Recently, China has overtaken the US as the largest beer economy. A quantitative empirical analysis studies the relationships among economic growth, globalisation and beer consumption. The relationship between income and beer consumption has an inverse U‐shape. Beer consumption initially increases with rising incomes; but at higher levels of income beer consumption falls. Increased globalisation has contributed to a convergence in alcohol consumption patterns across countries. In countries that were originally beer drinking countries, the share of beer in total alcohol consumption reduced, while this is not the case in countries which traditionally drank mostly wine or spirits.     

Demand for fish in Asia: a cross‐country analysis*

Fish demand patterns in nine Asian countries were investigated using a multistage budgeting framework allowing a disaggregated approach to analysing fish consumption. This paper highlights the heterogeneity of fisheries products in terms of species, sources and cultural responses of consumers, factors that are important in fish demand under the Asian setting. Specifically, fish demand by income groups were compared to determine how the low‐ and high‐income households respond to price and income changes. Results showed that the estimated price and income elasticities of all fish types included in the study were relatively more elastic among the poorer households.     

An Empirical Comparison of "Frisch" and "Time Series" Demand price Elasticities for individual Commodities

In a classical article in 1959, Ragnar Frisch [8] developed a procedure, which, under the assumption of want independence¹ and given commodity budget shares, income elasticities, and one own-price elasticity, allows one to calculate a complete matrix of own and cross price elasticities. Between broad commodity groups such an assumption (want independence) has becme increasingly accepted and in fact under the label of separability has formed the basis for a family of demand models that are increasingly used to estimate demand elasticities for broad commodity groups (the linear expenditure system, the Rotterdam model, etc.). At the individual commodity level however, the assumption of want independence seems less viable, e.g., the utility one derives from pork is in general not considered independent from one's consumption of beef. However, it has become increasingly common (and apparently acceptable) to find the Frisch methodology utilized to develop demand price elasticity estimates for individual agricultural commodities [4, 7, 17].     

Food Import Demand in the Czech Republic

This paper provides an overview of Czech food import demand in the transition period of the 1990s. It provides econometric estimates of own‐ and cross‐price elasticities as well as group expenditure elasticities of Czech import demand for sixteen lower level and four upper level food groups. Based on the Hausman test for endogeneity, which supported the hypothesis that Czech import prices were exogenously determined outside of the Czech economy, we estimated five demand models as direct‐demand systems of the AIDS type. The econometric estimation of elasticities used bimonthly data from March 1993 to August 1997.     

Price Endogeneity and Food Demand in Urban China

Price endogeneity has been ignored in previous analyses of food demand in urban China. We exploit data provided by the China National Bureau of Statistics on agricultural commodity supply shifters and use reduced‐form price equations to account for price endogeneity. Applying our unique econometric approach to the analysis of provincial‐level food demand in China, we find strong statistical evidence of price endogeneity. Models that ignore price endogeneity result in substantially biased elasticities and misleading estimates of future food demand in China.     

Demand under product differentiation: an empirical analysis of the US wine market*

Oversupply has led to a number of perplexities for the Australian wine industry in recent times. When disaggregated from the industry level, however, the problem can be better described as a range of attribute‐specific disequilibria. To date, the solutions to this problem have predominantly revolved around supply‐side policies of reducing output through crop thinning or vine pulling. By contrast, this paper focuses on the demand side and argues that the disequilibria may be reduced by gaining a better understanding of the demand for Australian wine. A discrete choice model of product differentiation is used to estimate the demand for wine in Australia's second largest export market, the United States. Implications of the analysis are explored.     

Price elasticities, joint products, and international trade

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 is implemented to calculate the elasticity of total demand for USA soybeans. The usefulness of this formula for policy–makers to trace out the impacts of changes in market conditions and trade policy in the joint–products, and how it will impact the price elasticity of domestic and total demand for the raw product, is demonstrated.
