Elaboración de harina de pescado OceanDocs
Silva Ortiz, S..
Almost one third of the worlds annual fish catch is used for processing into fish meal and oil. Peru and Chile are the main fish meal producing countries and they lead its commerce. Fish meal can be produced from any fish or shellfish, but fish offal from the consumption industry and the called 'Industrial fish' are mainly used. Nearly all the fish meal is produced by the wet pressing method that consists of cooking and pressing the raw material and subsequent drying and milling. There are several technologies specially designed to modify certain variables of the process in order to optimize its productivity and the quality of the final product. Fish meal quality depends on the type and freshness of the raw material, the applied thermal treatment and...

Fishing and poverty levels around Lake Victoria (Kenya) OceanDocs
Abila, R.O.; Omwega, R.N.; Lwenya, C..
Fishing is known to be one of the oldest occupations of mankind and in Lake Victoria (Kenya); it has been largely practiced at artisanal levels. Despite this, poverty amongst the fisher folk remains high. Why the fisher folk remain in perpetual poverty was the key research question for this study. Sampling was conducted on 12 landing beaches between June and August 2004. Data was obtained using survey questionnaires; personal interviews were made using open-ended questions and beach observations. Results from this study indicates that 179 fishers sampled earned an average income of Ksh. 107,063 each in a year with modal income of Ksh. 57,600 while in a day they earned an average income of Ksh. 518 each with modal income of Ksh. 200. Fishers perceived that...

RELATIONSHIPS BETWEEN MARKET PRICE SIGNALS AND PRODUCTION MANAGEMENT: THE CASE OF FED BEEF AgEcon
Outlaw, Joe L.; Anderson, David P.; Padberg, Daniel I..
The beef industry in the United States consists of several distinct production levels ranging from the cow-calf producer at the lowest level to the final consumer. These sectors face varying levels of profitability, degrees of market power, conflicting goals, and price signals. Environmental regulations involve questions of what costs are involved, who is in a position to pay these costs, and whether market prices are capable of signaling different environmental practices. Understanding the relationships within the beef industry may allow researchers to fine-tune analyses of environmental issues in the beef industry.

Can German Wine Cooperatives Compete on Quality? AgEcon
Schamel, Guenter.
The German Agricultural Society (DLG) manages a multi-round annual quality control scheme where wines undergo a blind, sensory testing procedure using a 5-point scale to determine superior quality wines worthy of an annual award (Bronze, Silver, Gold, and Gold Extra). We develop a hedonic model for the 2005 award competition estimating implicit prices for different product attributes including sensory awards, quality categories, and wine style. We also control for regional origin, variety, color, and age. To discern the impact of ownership structure, we distinguish cooperatives and private wineries. Silver and Bronze awards show significant price effects relative to Gold. We also estimate highly significant price effects between quality categories (e.g....

Testing the Theory: Vertical Strategic Interaction and Demand Functional Form AgEcon
Cotterill, Ronald W.; Putsis, William P., Jr..
Formulating theoretical models inevitably requires various simplifications that assist in making analysis tractable and that facilitate deriving closed form solutions. While the strategic insights gained from theoretical models of market phenomena are often quite valuable, testing the theoretical assumptions made in these models can aid in assessing the broader applicability of the conclusions drawn. This is particularly true in the channels area, where the focus of research to date has largely been theoretical in nature. In an initial attempt to examine some of the assumptions made in previous theoretical research (e.g., Jeuland and Shugan 1983, McGuire and Staelin 1983, Choi 1991, Raju, Sethuraman and Dhar 1995), we focus on a limited set of issues....

Does anybody give a dam? The importance of public awareness for urban water conservation during drought AgEcon
Aisbett, Emma; Steinhauser, Ralf.
Demand management has been of interest in dry climates such as Australia, Spain and the Western United States for decades. It is particularly important to understand policy options during drought conditions, as drought periods have a disproportionate effect on supply infrastructure decisions. While water‐conservation campaigns aimed at inducing voluntary consumption reductions are almost universally employed by water managers in times of supply constraint, voluntary measures are generally dismissed in the economics literature as ineffective. We argue that the robust positive correlation between dam levels and consumption after controlling for policy changes suggests that there is a significant component of voluntary conservation. Furthermore, omitting dam...

Wells and welfare in the Ganga Basin: Public policy and private initiative in Eastern Uttar Pradesh, India AgEcon
Shah, Tushaar.
This report analyzes how public policies designed to promote groundwater development over the past 50 years have failed in their promise, and how initiative by private agents can generate the social welfare the region needs so direly. The report outlines a five-pronged strategy for attacking eastern India's rural poverty through fuller utilization of its groundwater resources.

Do consumers benefit from private label development? AgEcon
Sckokai, Paolo; Soregaroli, Claudio.
In the European food sector private labels represent a relevant and increasing share of total sales. Thus, national brands need to adapt their marketing strategies to deal with this growing competition. Focusing on price strategies, recent theoretical papers conclude that private label development should cause a decrease in the price of national brands, while some empirical studies do not support this prediction. The aim of this study is to explore this empirical relationship for the Italian food retail sector, which is of special research interest, since it has undergone a dramatic change in the last 10 years. Using retail sales data, we build time series of market shares of prices of national brands and private labels for different dairy products and we...

Direct Marketing of Specialty Crops by Producers: A Price-Comparison between Farmers' Markets and Grocery Stores AgEcon
Watson, Jonathan Adam; Gunderson, Michael A..
Oftentimes, prices at farmers' markets are much cheaper than those at grocery stores. However, little is known about the pricing relationship between farmers' markets and nearby grocery stores. Only by further analyzing this relationship can we gain a better understanding of these pricing trends. Although this trend is seemingly consistent, further research is necessary to test this assumption. Through the collection of prices at both locales, farmers' markets and grocery stores, producers as well as consumers will have access to current prices in both markets. In recent years, consumers are looking for local produce and are willing to pay for them as they are faced with increased grocery store prices, while producers are simultaneously seeking to...

MARKETING OF WHEAT ON A CONSTANT AND NIL MOISTURE BASIS AgEcon
Wilson, William W.; Dahl, Bruce L..
This study examined moisture specification practices in the United States and for major exporters and assessed impacts of changes to a nil or constant moisture basis on prices and revenue. These were examined under scenarios where information on moisture in current prices is limited and under a scenario where current prices reflect Full Knowledge of moisture advantages. Results indicate that changing to a nil moisture basis (which requires a subsequent adjustment in volumes to reflect the subtraction of moisture) would increase reported prices from 42 to 70 c/bu for the wheat classes, while changing to a 12 percent constant moisture basis would have limited impacts on reported prices. Effects on relative prices/revenue depend on whether knowledge of...

SEASONALITY OF CLASS I PRICE DIFFERENTIAL ESTIMATES FOR THE SOUTHEASTERN UNITED STATES AgEcon
Testuri, Carlos E.; Kilmer, Richard L.; Spreen, Thomas H..
This study provides insight into the seasonality of Class I price differentials in the southeastern dairy industry. This is accomplished by analyzing monthly estimates of Class I price differentials obtained from the imputed price solution or dual solution of a generalized capacitated minimum cost network flow model of the dairy industry. A smooth seasonal pattern emerges through the monthly sequence with the lowest and highest estimated Class I price differentials occurring in April and September respectively. Miami and Jacksonville areas reach $5.40 and $4.36 per hundredweight in April and $6.79 and $5.53 per hundredweight in September.

Pedaling out of poverty: Social impact of a manual irrigation technology in South Asia AgEcon
Shah, Tushaar; Alam, Mahmudul; Kumar, M. Dinesh; Nagar, Rashmi K.; Singh, Mahendra.
An assessment of the social impact of treadle pump technology for manual irrigation in eastern India, the Nepal Terai, and Bangladesh, South Asia's so-called "poverty square." Treadle pump technology can be a powerful tool for poverty reduction in this region. It "self-selects" the poor, and puts to productive use the region's vast surplus family labor. It is claimed that the treadle pump could raise the annual net household income by US$100, on the average.

PUBLIC BASIC RESEARCH AND DIFFUSION OF RESEARCH BENEFITS AgEcon
Malla, Stavroula; Gray, Richard S..
The paper examine the economic impact of pricing and access to basic research IP. The analysis uses a Sallop circle model of a monopolistically competitive industry to examine the applied research output and firm entry. Under plausible conditions basic research IP spillovers will create rents for the applied research sector, which are dissipated through socially excess firm entry. Charging a price or restricting access to basic research IP could enhance social welfare.

An Analysis of the Recent Evolution of Mali’s Maize Subsector AgEcon
Diallo, Amadou Sekou.
In most developing countries, historically, the main strategy for improving the food sector has focused on increasing farm-level production. But in recent years, with the emphasis on value chain analysis, there has been much more focus on subsector studies, demand-driven approaches, and improving vertical coordination to assure product quality to final consumption markets. Millet, sorghum, and later rice were the traditional leading three cereal crops produced and consumed in Mali. Maize has trailed them for more than two decades, but from mid 1990s on, it has been produced and consumed in much larger quantities. Given the potentials of maize, developing and better organizing its subsector has the potential to not only increase revenues for maize farmers,...

PRICING WEATHER DERIVATIVES FOR AGRICULTURAL RISK MANAGEMENT AgEcon
Richards, Timothy J.; Manfredo, Mark R.; Sanders, Dwight R..
Existing derivative pricing methods cannot be used to price weather derivatives due to the absence of a hedgeable commodity underlying weather risk and the complexity of weather processes. This study develops a pricing model that considers weather derivatives to be the same as any other financial asset. In this way, the price of a weather derivative is an equilibrium price consistent with both the potential payout at expiry and the market price of risk. We apply this model to the pricing of weather derivatives in the Central Valley of California and find significant differences in prices obtained under alternative weather process assumptions.

Tart Cherry Yield and Economic Response to Alternative Planting Densities AgEcon
Me-Nsope, Nathalie Mongue.
The study investigates the economic response of tart cherry yields to planting density using an unbalanced longitudinal yield data from tart cherry orchards in Northwest Michigan. The relationship between tart cherry yield and tree age is specified as a linear spline function and planting density interacts with tree age. A random effect method, treating block as random, is used to estimate the spline function. Stochastic simulation was used to estimate the mean and variance of the product of two random variables (price and yield), and the coefficient of variation was used as a measure of how much risk is involved in corn/soybeans production relative to tart cherries production. Estimates of the variance provided the discount factor (10%) and with yields...
