Última HOW LARGE ARE NON-BUDGET-CONSTRAINT EFFECTS OF PRICES ON DEMAND? AgEcon Heffetz, Ori; Shayo, Moses. Elementary consumer theory assumes that prices affect demand only because they affect the budget constraint (BC). By contrast, several models suggest that prices can affect demand through other channels (e.g. because they signal quality). This alternative conjecture is consistent with evidence from marketing studies. However, neither theory nor evidence is informative regarding the magnitude of non-BC effects. The key econometric challenge arises from the fact that a change in prices typically also changes the BC. This paper uses a lab and a field experiment to disentangle BC from non-BC effects of prices on demand. In our lab experiment we find that, consistent with marketing evidence, prices positively affect stated willingness to pay. However, when...

Silva Filho,Jairo Vieira da; Figueira,Sérgio Rangel Fernandes. ABSTRACT The objective of this study was to measure the short- and long-term elasticities of the Gross Domestic Product (GDP), productivity, prices paid to producers, milk powder imports, minimum wages, and exchange ratios in milk collection between 1999 and 2016. For the measurement, the cointegration technique for data in a balanced panel was used, contemplating five states with great representativeness in the Brazilian industrial milk collection: Minas Gerais, Paraná, Rio Grande do Sul, Goiás, and São Paulo. These states corresponded to 73.3% of all formal milk collection in 2016. Results indicated that GDP, productivity, and imports impacted long-term milk collection. Productivity and GDP were the variables with the greatest long-term impact, with... Tipo: Info:eu-repo/semantics/article Palavras-chave: Economy; Milk; Multiple regression; Price.

Economic theory suggests that price incentives can be used to encourage water conservation in residential consumers. Conservation water rates are designed to send price signals that encourage households to reduce discretionary water use in the long term. However, it is not always clear that conservation rates effectively provide meaningful incentives. Utilities themselves may also not have strong incentives to implement conservation rates. If conservation rates have a negative impact on revenue, or if they lead to increased revenue variability, utilities may have a disincentive to use them. In addition, block pricing structures (where unit water rate increases with water usage) may be inequitable, in the sense that the “revenue burden” is borne...

La actividad pecuaria es de gran importancia socioeconómica para el país; la ganadería, en específico la producción de carne, es la actividad más diseminada en el sector rural. Se estima que la superficie aprovechada por la ganadería es superior a 110 millones de hectáreas, aproximadamente 60% del terrritorio nacional (SAGARPA, 2000). En el presente trabajo se estiman los efectos que se tiene sobre las cantidades ofrecidas de carne de res a nivel de granja ante un incremento en el precio del maíz, sorgo y pan. Los incrementos utilizados sobre los precios de los granos fueron del 5%, 10% y 15%, estos son ingredientes básicos en la dieta de bovinos.

Ano: 2013 URL: http://hdl.handle.net/10521/1858 Market Access by Smallholder Farmers in Malawi: Implications for Technology Adoption, Agricultural Productivity, and Crop Income AgEcon Zeller, Manfred; Diagne, Aliou; Mataya, Charles. In Malawi, maize is the major crop and food staple. Given limited off-farm employment opportunities, much-needed increases in household income for improving food security must come from gains in agricultural productivity through better technology and more profitable crops. In the past, agricultural policy promoted hybrid maize and, more recently, tobacco to increase smallholder income. This paper presents an analysis of what determines the adoption of these two crops and what kind of income effects follow from adoption. Apart from factor endowment and exposure to agroecological risks, differences in the household's access to financial and commodity markets significantly influence its cropping shares and farm income.

In the developed countries, especially in the European Union, demand for seafood products has increased very quickly (faster than that of meat products). This growth may be explained by the recurring problems of animal health impacts on other products (bovine spongiform encephalopathy (BSE), avian influenza (bird flu)...) and to the impacts of the environmental problems (dioxins...) which are less prevalent in seafood products. In addition, seafood products profit from an increasingly positive image positioned on the axis of nutrition- health. The enhancement of the markets is influenced more and more by the retailing channel (hyper and supermarkets). Indeed, France profits from being a pioneer in retailing, (more than 70% of the seafood market is through...

This study analyzed the effects that the use of crop insurance products and marketing alternatives had on the gross revenue per acre for an individual farm in Cass County. Crop insurance products and marketing strategies were analyzed individually to determine if they were effective in minimizing down side risk, and combined to determine if integration created synergies. A whole farm scenario analysis was run that included integrated strategies that implemented the same insurance coverage and marketing alternatives for each crop. Several general conclusions can be drawn for situations similar to the representative farm. When analyzed at the individual crop level, the use of crop insurance at the 65 percent level minimizes down side risk in wheat and corn,...

Ano: 2001 URL: http://purl.umn.edu/23517 MODELLING THE DYNAMICS OF PRODUCTION ADJUSTMENT TO SHORT-TERM MARKET SHOCKS AgEcon Niemi, Jarkko K.; Lehtonen, Heikki. Models of agricultural economics typically operate at an annual basis or in a static equilibrium framework where inputs, outputs and their prices may change considerably. Production dynamics, however, imply that models relying on spatial and temporal aggregation do not capture the effects of biological constraints in the short run. This paper examines short and long-term impacts of demand and production cost shocks in the pig sector. The analysis is carried out with a dynamic programming model which takes into account changes in export and domestic demand and market clearing price. It optimizes the supply of piglets on a monthly basis. Econometric techniques are used to estimate demand functions. Short-term negative market shocks can already have...

Ano: 2008 URL: http://purl.umn.edu/112722 Payments under the Average Crop Revenue Program: Implications for Government Costs and Producer Preferences AgEcon Cooper, Joseph C.. This paper develops a stochastic model for comparing payments to U.S. corn producers under the U.S. Senate’s Average Crop Revenue Program (ACR) versus payments under the price-based marketing loan benefit and countercyclical payment programs. Using this model, the paper examines the sensitivity of the density function for payments to changes in expected price levels. We also assess the impact of the choice of yield aggregation used in the ACR payment rate on the mean and variance of farm returns. We find that ACR payments lower the producer’s coefficient of variation of total revenue more than does the price-based support, although ACR may not raise mean revenue as much. While corn farmers in the heartland states might still prefer to receive the...

Ano: 2008 URL: http://purl.umn.edu/106106 Public policy and some-day smoking among adults AgEcon Tauras, John A.. While much is known about the impact of public policy on current cigarette smoking among adults, very little is known about the determinants of some-day smoking. This paper investigates the impact of cigarette prices, clean indoor air laws, and other socioeconomic factors on adult cigarette demand. Special emphasis is placed on examining the determinants of some-day smoking among adults. The estimates from this study clearly indicate that increasing the price of cigarettes, will decrease the number of people who currently smoke, will decrease the number of every-day smokers, and will decrease the number of cigarettes smoked on average among some-day smokers. Finally, clean indoor air laws are found to have a limited impact on current and some-day smoking. Tipo: Journal Article Palavras-chave: Policy; Price; Smoking; Some-day; I18. Ano: 2004 URL: http://purl.umn.edu/43879 Regulating Stock Externalities Under Uncertainty AgEcon Newell, Richard G.; Pizer, William A.. Using a simple analytical model incorporating benefits of a stock, costs of adjusting the stock, and uncertainty in costs, we uncover several important principles governing the choice of price-based policies (e.g., taxes) relative to quantity-based policies (e.g., tradable permits) for controlling stock externalities. Applied to the problem of greenhouse gases and climate change, we find that a price-based instrument generates several times the expected net benefits of a quantity instrument. As in Weitzman (1974), the relative slopes of the marginal benefits and costs of controlling the externality continue to be critical determinants of the efficiency of prices relative to quantities, with flatter marginal benefits and steeper marginal costs favoring...

This paper analyzes how Cambodian farmers and the government can respond to the rise of rice price. The study estimates rice production response in Cambodia using the Cambodia Socio-Economic Surveys (CSES) conducted in 2004 and 2007. The results indicate that agricultural productivity is far from its potential and can be increased substantially by using modern technology and inputs such as fertilizers and irrigation. Our findings also suggest that the Cambodian government needs to design its investment strategy to relax constraints in rural infrastructure such as transportation and electricity in order to increase its agricultural production and productivity and boost farmers’ income.

Southern dairy farmers' perception of their cooperative's or proprietary handler's performance, level of satisfaction with the milk handler, and reasons for staying with the handler, or for shifting handlers, were evaluated. The data were from a 1989 mail survey of Southern dairy farmers. The dairy farmers' differing evaluations of their milk handlers depended on the type of handler they dealt with, geographic location, and/or the characteristics of the farm and farmer. Generally, dairy farmers were concerned about price, deductions, and assessments. The price farmers received appeared to be a significant factor affecting farmers' satisfaction level. There appeared to be a tradeoff between price and deductions versus service, and market and payment...
