Última Access to Dynamic Markets for Small Commercial Farmers: The Case of Potato Production in the Peruvian Andes AgEcon Escobal D'Angelo, Javier; Torero, Maximo. The purpose of this study is twofold. On one hand, the objective is to assess the impact of new and more complex contracting schemes, as opposed to traditional marketing channels, on small farmers’ welfare. On the other hand, the study explores which may be the critical factors that determine the small farmers’ participation in these institutional arrangements. In this context, two critical factors are stressed. The first one has to do with access to credit and the second one is the size of the agricultural plot. In order to examine the decision of farmers to access the dynamic markets, the paper follows the study of Lapar et al (2003). The paper also follows impact evaluation techniques to identify the differences in the performance of farmers with access...

Ano: 2006 URL: http://purl.umn.edu/58570 Access to Dynamic Markets for Small Commercial Farmers: The Case of Potato Production in the Peruvian Andes AgEcon Escobal D'Angelo, Javier; Torero, Maximo. The study has evaluated which are the most relevant factors that determine that a small farmer switch marketing channels in order to enter into a "dynamic" market; that is, into a market signed by more complex contractual relationships that can absorb increasing amounts of its output. The results show that there are a number of producers that currently are not selling to those markets but they may well do so. Restrictions associated to the degree of organization of the producers, their perception of risk and credit market restrictions may prevent these farmers to gain access to the additional benefits that these new market opportunities have to offer.

Ano: 2006 URL: http://purl.umn.edu/25667 ACCESS TO INFORMATION AND FACTOR MARKET PARTICIPATION: ADJUSTMENTS OF LAND AND LABOUR MARGINS OF AGRICULTURAL HOUSEHOLDS IN BANGLADESH AgEcon Chowdhury, Shyamal K.. This paper assesses the impact of access to information on farm household's factor market participation. The paper tries to answer two questions. First, does use of telephone have any impact on farm household's factor market participation decision? Second, correcting for market participation, does use of telephone have any impact on the type of factor adjustment decision? For the first question, the paper uses a bivariate probit to correct for omitted variable bias and for the second question, the paper uses a two stage probit. Empirical findings of this paper suggest that access to information in the form of use of telephone has significant positive impact on factor market participation. The difference in market participation between telephone users and... Tipo: Conference Paper or Presentation Palavras-chave: Consumer/Household Economics; Marketing.

Using a world agricultural multimarket model, we analyze the consequences of enlargement of the European Union (EU) to include the Czech Republic, Hungary, and Poland for agricultural markets. We produce a market outlook through the year 2010 for two enlargement scenarios, which are based on different assumptions regarding the restrictions on grain and dairy production in the acceding countries. In both scenarios, accession of the three Central and Eastern European countries (CEECs) leads to a permanent but moderate decrease in EU prices for virtually all commodities. For the three acceding CEECs, domestic prices increase dramatically. Their final consumption of agricultural products decreases in most instances, while production rises. Higher domestic...

Ano: 2000 URL: http://purl.umn.edu/18388 ACCURACY OF GRID PRICING: AN EVALUATION USING WHOLESALE VALUES OF FED CATTLE AgEcon Kovanda, Joseph T.; Schroeder, Ted C.; Wheeler, Tommy L.. Grid pricing is one of the beef industry's answers to improving value coordination in fed cattle transactions. This paper constructs individual carcass-level grid and wholesale beef values. These values are used to evaluate the level of value communication that occurs between wholesale and grid values of beef. Furthermore, the values are used to estimate grid premiums/discounts that improve value communication. Results indicate that value coordination could be improved by modifying grid premiums/discounts.

Implied volatility is a useful bit of information for futures and options hedgers and speculators. However, extraction of implied volatility from Black-Scholes (BS) option pricing model requires a numeric search. Since 1988, there have been numerous simplifying modifications to the BS formula proposed and presented in the applied economics and finance literature to allow approximation of implied volatility directly. This study identifies and tests these simplification methods for accuracy for call only and put-call average elicitation of an implied volatility estimate. Results show that accuracy varies by method and whether call only or put-call average approaches are applied. Tipo: Conference Paper or Presentation Palavras-chave: Marketing.

One maxim that has been circulating among farmers is that most farmers sell in the lower third of the market. This maxim is soundly rejected using data from Oklahoma elevators. In fact, roughly half of producers sell in the upper third of the market. Thus, there does not seem to be a great need for producers to hire a market advisor to do their marketing for them. But, some farmers do store longer than is optimal and they could be encouraged to sell sooner after harvest. In the short run, farmers sold after price increases and held after price decreases. Price movements in the days after a large number of sales were no different than price movements after few sales. While farmers are noise traders in the short run, it does appear that they are responding... Tipo: Conference Paper or Presentation Palavras-chave: Marketing.

A bivariate probit model was used to examine the relationship between actual and intended purchase of irradiated beef. The likelihood ratio test rejected the equality of parameters affecting actual and intended purchase decisions. Actual purchases were affected by package labels and appearance, while purchase intentions were affected by attitude and demographics.

Ano: 1999 URL: http://purl.umn.edu/21548 Adoption Behavior in Food Retailers' Decision to Offer Fresh Irradiated Ground Beef AgEcon Jaenicke, Edward C.; Harrison, R. Wes; Jensen, Kimberly L.; Jakus, Paul M.. During the 14-month period from May 2002 to June 2003, approximately 10 percent of U.S. supermarkets began to offer fresh irradiated ground beef under the stores' own labels. Using a survey of supermarket store managers from this time period, this paper investigates the factors that influenced stores' adoption of irradiated ground beef. Results from the adoption model show that factors associated with competition, merchandising philosophy, and structure in the food retailing industry play a strong role in the decision. Among other results, we find that variables relating to a competitor's adoption status and proximity can increase the likelihood of a store's adoption decision.

This paper analyzes the factors guiding Internet and e-commerce implementation by agribusiness firms. The relationship between Internet/e-commerce strategies and manager perceptions on the barriers and factors to e-commerce adoption are analyzed in a supply-chain management framework. Using factor analysis and an ordered Probit model, results indicate that the implementation of Internet/e-commerce strategies is more likely to be adopted in larger firms with a global scope. Also, manager perceptions regarding supply-chain functions influencing transaction costs are more strongly associated with Internet/e-commerce adoption than other functions influencing production costs.

Ano: 2000 URL: http://purl.umn.edu/21771 Adoption of E-Marketing by Direct-Market Farms in the Northeastern United States AgEcon Baer, Alexander G.; Brown, Cheryl. Many farms have begun operating websites in order to promote their businesses. This study uses data from a 2005 survey of farms in the northeastern United States to identify characteristics of farmers, farms, and farm businesses associated with website adoption. Following a technology-adoption framework, a probit model of website use is estimated to identify significant relationships. Sales location, product type, number of advertising methods used, high-speed Internet connection, land tenure arrangement, and gross farm sales is found to be significantly related to website adoption.

The pig meat market in Australia is characterized by generic (fresh pork, bacon etc.) advertising. These advertising expenditures are funded from collective levies from pig producers. At the same time, there are extensive brand advertising activities in the pig market. Impact of advertising on pig meat consumption has been a long-standing argument. So far, there have been several studies done on the effectiveness of generic pork advertising in Australia up to 1988. However, the previous studies only looked at generic advertising and didn’t account for other media information as brand advertising and fast food advertising effects on pork consumption. As well, the previous studies are contradictory about the effects of generic pork advertising. In this... Tipo: Presentation Palavras-chave: Agribusiness; Marketing. Ano: 2000 URL: http://purl.umn.edu/123744 Advertising and Promotion Investment: What Is the Right Level? AgEcon Forker, Olan D.. Agricultural economists in both the United States and Canada have been trying to answer this complicated question for over 12 years. Although there is no simple answer t researchers generally agree that the "right level" of advertising investment is a function of the promotion program's objective. The actual level of advertising investment in 1987 totaled $490 million in 22 dairyproducing countries. The United States t Canada t Australia t and the United Kingdom have similar levels of promotion investment per unit of milk production ($0.12 to $0.17 per hundredweight). A review of economic studies "indicates commodity advertising investment in the U.S. is probably less than optimum at its current level of around $145 million.

Ano: 1990 URL: http://purl.umn.edu/121547 Advertising and Retail Promotion of Washington Apples: A Structural Latent Variable Approach to Promotion Evaluation AgEcon Richards, Timothy J.; Gao, Xiaoming; Patterson, Paul M.. "Commodity promotion" consists of many activities, each designed to contribute to a consumer's product knowledge or influence tastes. However, both knowledge and tastes are unobservable, or latent, variables influencing demand. This paper specifies a dynamic structural model of fresh fruit demand that treats promotion and other socioeconomic variables as "causal" variables influencing these latent variables. Estimating this state-space model using a Kalman filter approach provides estimates of both the system parameters and a latent variable series. The results show that these latent effects contribute positively to apple and other fruit consumption, while reducing banana consumption.

In this paper we consider the role for collective action in advertising investments needed to compete on foreign markets and/or to enter into new markets. We model the choices facing producers in regions where both AO (high quality) and table (low quality) wines are produced. By joining forces with producers of other regions to invest in advertising, producers may penetrate into new markets. We show that it is profitable to enter into the new markets when, other things being equal, the size of the new market is relatively big, when the traditional market is relatively small, and when the size of the fixed investment in advertising is relatively small. We discuss the policy implications of the results, examining possible modifications of the AO system... Tipo: Journal Article Palavras-chave: Marketing.
