Abstraction and Product Categories as Explanatory Variables for Food Consumption AgEcon
Barrena Figueroa, Ramo; Sanchez Garcia, Mercedes.
An understanding of the process by which consumers match consumption choices to personal values is powerful aid to guide strategic market orientation. It is of particular importance in the highly saturated food markets of developed countries, where consumer needs are shifting closer and closer towards the search for quality and emotional benefits. This study sets out to explore variation in the consumer choice structure in relation to three products with different levels of search, experience and credence attributes, using means-end chain theory. The results suggest the presence of an emotional component in foods that increases in complexity (becomes more abstract) with the number of credence attributes associated with the product; a fact worthy of the...

Agricultural markets in Benin and Malawi AgEcon
Fafchamps, Marcel; Gabre-Madhin, Eleni Z..
Based on original trader surveys, this paper examines how agricultural traders operate in Benin and Malawi. Results indicate that the largest transaction costs are search and transport. The use of modern technology is limited. Search methods rely principally on personal visits by the trader, and quality control requires the presence of the trader at the time of purchase. This increases costs, as the trader has to travel a lot, and makes it difficult for trading enterprises to grow. Since enterprises remain very small, personal transport and search time represent a non-negligible share of marketing costs.

CAN INCOME EQUALITY INCREASE COMPETITIVENESS? AgEcon
Fishman, Arthur; Simhon, Avi.
This paper explores the relationship between income distribution, prices, production efficiency and aggregate output in a decentralized search economy. We show that income distribution determines how competitive the market is, and thereby affects production efficiency and aggregate output. It is shown that it is generally possible to engineer a judicious transfer of income from high to low income individuals which simultaneously increases income equality, competitiveness, and aggregate output.

Consulta Regional sobre la Politica Rural del Banco Interamericano de Desarrollo AgEcon
Berdegue, Julio A.; Trivelli, Carolina; Araya, Catalina.
This article is a document of great bibliographical value because it is a search at an international level. It was conducted in Latin-America to review the rural politics of the Inter-American Bank of Development. The author and his collaborators summarize and make short each one of the opinions given by specialists, experts and studious professionals of primary economy within the Inter-American region. This is the reason why the magazine wants to publish this important and interesting essay which completely illustrates us about the importance of socioeconomy.

Definitions of Biodiversity and Measures of Its Value AgEcon
Simpson, R. David.
The destruction of natural habitats has prompted concerns about the loss of biological diversity. Regrettably, however, there is no consensus among either biologists or economists on the most meaningful measures of biodiversity. Fundamentally different definitions are useful in asking fundamentally different questions. Considerable attention has been given to the value of diversity in search models. A measure of "aggregate variability" is appropriate to such models. Values derived from search models tend to be well behaved; they exhibit diminishing returns in diversity. In contrast, a definition of diversity as "relative abundance" is more appropriate to more complex objective functions. Values derived in these models are not necessarily well behaved. The...

From the help desk AgEcon
McDowell, Allen.
Welcome to From the help desk. From the help desk is written by the people in Technical Services at StataCorp and deals with issues that they have found to be of concern to a large fraction of Stata users. It is the rare column in this series that deals with sophisticated programming issues because such issues, by definition, are not of concern to a large fraction of Stata users. From the help desk discusses the use of sophisticated programs and the use of sophisticated statistics.

Long-Term Unemployment and Subsidizing Vacancies in a Growth-Matching Model AgEcon
Birk, Angela.
How can long-term unemployment be reduced by policy measures of the government? In this paper a growth-matching-model is developed, in which the unemployment pool consists of heterogeneous unemployed workers, short-term and long-term unemployed, and with an endogenous skill-depreciation of the long-term unemployed emerging as technical progress accelerates. For innovation countries characterized by rapid technical progress we show that through subsidizing vacancy creation which causes a substitution and an income effect long-term unemployment can be reduced. Since the positive substitution effect implied by subsidizing vacancy creation outweighs the negative income effect induced by taxing the household's income, a positive employment effect results...

Qualification-Mismatch and Long-Term Unemployment in a Growth-Matching Model AgEcon
Birk, Angela.
How does technical progress affect long-term unemployment? The relationship between long-term unemployment and the rate of growth attributable to technical progress is evaluated in a growth-matching-model with heterogeneous jobless workers and with endogenously determined long-term unemployed resulting from skill-depreciation. For innovation economies characterized by high steady-state levels of capital intensities the model shows that, due to a capitalization effect and a qualification-mismatch effect, increasing technological progress has adverse implications for long-term unemployment. Furthermore, for imitation economies with low steady-state capital intensities increasing technological progress can be either favorable or less favorable for long-term...

Valuation of Biodiversity for Use in New Product Research in a Model of Sequential Search AgEcon
Simpson, R. David; Sedjo, Roger A..
We develop a model of search in which a researcher chooses the size of sequential batches of samples to test. While earlier work has considered similar questions, the contribution of this paper is to use the search model to place a value on the marginal research opportunity. The valuation of such opportunities may be of little interest or relevance in many of the contexts in which search models are employed, but we apply our analysis to an area of considerable societal interest: the valuation of biological diversity for use in new product research. While data from which to make inferences are limited, we find that, using plausible estimates of relevant parameters, the value of biodiversity in these applications is negligible.

Whale-watching and Herring Fishing: Joint or Independent Production? AgEcon
Lee, Min-Yang A..
The effects of "localized depletion" of a pelagic fishery (herring) on a non-extractive marine activity (tourism) are investigated. Proponents of the localized depletion theory claim that intense fishing effort can lead to areas that are unsuitable for predators like tuna, groundfish, and whales. This leads to poor outcomes for the fishing and whale-watching industries. However, there has been no consensus in the scientific community about the existence of this phenomenon. Localized depletion would be consistent with an economic theory of joint production, in which nearshore herring stocks are an input in production of both herring and whale-watching trips. A unique dataset of daily whale-watching outcomes is combined with fishing effort and oceanographic...
