Impacts of food safety on beef demand
This study investigates whether food
safety incidents involving beef, pork, and
poultry, and the accompanying publicity
have impacted United States meat demand.
Beef demand is modeled as a function of
beef prices, competing meat prices, meat
expenditures, and food safety. Food safety
indices are constructed separately for beef,
pork, and poultry.
Statistical tests reveal significant effects
of food safety incidents on beef demand.
The effect of an additional beef food safety
incident on beef demand is negative,
implying a detrimental impact on beef
consumption. Spillover effects of pork and
poultry safety incidents are positive and
improve beef demand, revealing
substitution away from pork and poultry
towards beef. In other words, food safety
incidents involving beef decrease beef
demand and those involving pork or
poultry increase beef demand. Overall, the
demand responses to food safety incidents
are small when compared to price effects
and to previously reported estimates on
health effects, such as information relating
to beef and cholesterol
Asymmetry in beef, lamb and pork farm-retail price transmission in Australia
The hypothesis of asymmetry in price transmission within the Australian meat market is tested using monthly
data for beef, lamb and pork prices at different market levels over the period 1971-1988. The results indicate that
asymmetrical price response is a strategy used by beef and lamb retailers and wholesalers to adjust to changing input
prices, but not by pork retailers and wholesalers. This difference is perhaps unexpected given the similarity in
behaviours relating to price levelling in this market, the high cross-price elasticities of demand between these meats,
and the relatively greater degree of concentration in the pork market
The Nested PIGLOG Model: An Application to U.S. Food Demand
A new demand system is introduced, the Nested PIGLOG model, nesting thirteen other demand systems including five that are also new. This new model and its nested special cases are applied to models of U.S. food demand that include food-at-home (FAH), food-away-from-home (FAFH), and alcoholic beverages. Although nested tests and out-of-sample forecasting performance favor generalizing models to a certain degree, statistically insignificant improvements to in-sample-fit and even poorer out-of-sample forecast accuracy undermine further generalizations. Based on a subset of preferred models, FAFH is found to be price and income elastic compared to FAH which is price and income inelastic. Copyright 2003, Oxford University Press.

Sistemas de equações de demanda por carnes no Brasil: especificação e estimação
Especificações alternativas do sistema de demanda quase ideal (AIDS) foram utilizadas para estimar as demandas agregadas das carnes bovina, suÃna e de frango e outros bens de consumo e as suas elasticidades no Brasil. Detectada a necessidade de se utilizar a variável tendência nas equações dos modelos, observou-se uma tendência de crescimento da demanda por carnes e de decrescimento da demanda por outros bens de consumo. A variável dummy para o Plano Real indicou que o mesmo não afetou as demandas. Com base nas elasticidades próprios-preços Marshallianas, as demandas por carnes são inelásticas e a demanda por outros bens de consumo é elástica. As elasticidades preços-cruzados Marshallianas e Hicksianas confirmaram que as carnes bovina, suÃna e de frango são bens substitutos. As elasticidades-gasto indicaram que todos os bens são normais, exceto a carne suÃna que é um bem inferior. Como é provável que o gasto com o consumo das famÃlias aumente ao longo do tempo, ceteris paribus, as elasticidades gasto indicam que a demanda por carnes perderá importância para os outros bens de consumo, que o consumo de carne bovina perderá importância para a carne de frango e que o consumo de carne de porco perderá importância para as outras carnes
