Farm Productivity and Household Market Participation: Evidence from LSMS Data AgEcon
Rios, Ana R.; Shively, Gerald E.; Masters, William A..
We analyze the correlation between farm productivity and market participation using comparable household data from Tanzania, Vietnam and Guatemala. Each farm’s input use and output levels provide a within-sample measure of relative productivity, which we relate to that household’s level of participation in local markets using a wide range of agricultural, demographic and infrastructural variables as controls and as instruments in two-stage regressions. Results indicate that, controlling for differences in market access and the underlying determinants of market participation, households with higher productivity have greater participation in agricultural markets. In contrast, households with greater rates of market participation do not consistently...

Analisis de convergencia en productividad agraria en las regiones europeas AgEcon
Valero, Juan Sebastian Castillo; Cuerva Narro, Maria Carmen.
RESUMEN: En este artículo se estudia la convergencia regional desde un punto de vista sectorial, centrada en el sector agrario. En el desarrollo del mismo se hace eco de la relevancia del sector agrario para una explicación histórica de las desigualdades territoriales en la Unión Europea y se analiza la evolución de la desigualdad y la convergencia de las agriculturas en las regiones europeas durante el periodo 1985-1997 a través del valor añadido agrario por ocupado. La existencia de un proceso de convergencia a niveles absolutos entre las economías regionales agrarias es un hecho constatado en el análisis. Sin embargo, las peculiaridades específicas de cada territorio hacen que no podamos hablar de una posición de equilibrio común, sino que las...

The Dissemination of Private Wells and Double Tragedies: The Overexploitation of Groundwater among Well Users and Increased Poverty among Non-Well Users in Tamil Nadu, India AgEcon
Kajisa, Kei; Palanisami, Kuppannan; Sakurai, Takeshi.
This paper investigates the impact of the dissemination of modern irrigation systems, i.e. private wells with pumps, on the livelihood not only among the farmers who have access to wells but also among the farmers who have no access to wells and thus rely solely on traditional irrigation systems called tank irrigation systems. The analysis is based on a village and household data set collected in Tamil Nadu, India where tank irrigation systems have been managed collectively for rice cultivation. Our statistical analyses predict that once declines in collective management occur due to the dissemination of private wells, the rice yield and income of the no-well-access farmers alone will decrease, resulting in increased poverty among them. Our analyses also...

What are the social impacts of land use restrictions on local communities? Empirical evidence from Costa Rica AgEcon
Andam, Kwaw S.; Ferraro, Paul J.; Holland, Margaret B..
Global efforts to reduce deforestation rely heavily on protected areas and land use restrictions. The effect of these restrictions on local communities is currently the subject of heated debate among conservation and development experts. Measuring the social impacts of protected areas is difficult because the effects cannot be isolated from other factors, given the nonrandom placement of protection. We address this problem by applying a quasi-experimental approach to establish the counterfactual (“what would have been the socioeconomic outcome if a protected area had not been established?”). We use matching methods to measure the impacts of pre-1980 protected areas in Costa Rica on socioeconomic outcomes in 2000. In 2000, neighboring communities near...

A Trend Deduction Model of Fluctuating Oil Prices AgEcon
Xu, Haiyan; Zhang, ZhongXiang.
Crude oil prices have been fluctuating over time and by a large range. It is the disorganization of oil price series that makes it difficult to deduce the changing trends of oil prices in the middle- and long-terms and predict their price levels in the short-term. Following a price-state classification and state transition analysis of changing oil prices from January 2004 to April 2010, this paper first verifies that the observed crude oil price series during the soaring period follow a Markov Chain. Next, the paper deduces the changing trends of oil prices by the limit probability of a Markov Chain. We then undertake a probability distribution analysis and find that the oil price series have a log-normality distribution. On this basis, we integrate the...

Political Economy of Agricultural Distortions in Transition Countries of Asia and Europe AgEcon
Rozelle, Scott; Swinnen, Johan F.M..
The paper analyzes the political and institutional factors which are behind the dramatic changes in distortions to agricultural incentives in the transition countries in East Asia (China and Vietnam), Central Asia (Kazakhstan, Kyrgyz Republic, etc), the rest of the former Soviet Union, and in Central and Eastern Europe. The paper explains why these changes have occurred and why there are large differences among transition countries in the extent and the nature of the remaining distortions.

Food Calorie Intake and Food Security under Grain Price Inflation: Evidence from Malawi AgEcon
Pan, Suwen; Fang, Cheng; Sanogo, Issa; Mutuc, Maria Erlinda M..
A comprehensive analysis of food demand and nutrient consumption using recent, representative household survey data from Malawi is presented. Expenditure and price elasticities have been estimated for 20 food groups using a quadratic almost ideal demand system based on 4 income groups identified by the Goldfeld-Quandt tests. Although the current boom of maize price provides an opportunity to rethink development strategies that diversify the commodity sectors, developing countries will not necessarily benefit from this change absent significant improvements in production capacities and trade infrastructures. Malawi is likely to suffer from higher commodity prices in the short-run.

Friction and the Multiplicity of Equilibria AgEcon
Karp, Larry S.; Paul, Thierry.
In familiar models, a decrease in the friction facing mobile factors (e.g., lowering their adjustment costs) increases a coordination problem, leading to more circumstances where there are multiple equilibria. We show that a decrease in friction can decrease coordination problems if, for example, a production externality arises from a changing stock of knowledge or a changing environmental stock. In general, the relation between the amount of friction that mobile factors face and the likelihood of multiple equilibria is non-monotonic.

The Initial Impact of WTO Membership on China's Trade Performance in Primary Agricultural And Processed Food Products AgEcon
Xue, Liu; Revell, Brian J.; Zetian, Fu.
There has been much analysis of the potential impact of China's membership of the WTO on world trade in agricultural products but few studies of the actual effects thus far on China's trade performance. This paper compares changes in the competitiveness of China's trade in primary agricultural food and processed food products over the period 1998 to 2003 through a range of comparative advantage measures, the preferred being Revealed Symmetric Comparative Advantage. It also decomposes changes in China's export market share of these products over the period into structural and performance components and identifies where shifts in the global regional distribution of its exports have contributed to changes in its overall market share.

Food Aid and the WTO: Can New Rules Be Effective? AgEcon
Cardwell, Ryan T..
A new Agreement on Agriculture from the Doha Development Agenda negotiations is certain to contain binding rules on food aid shipments. Negotiating parties are concerned that food aid has been used as a form of export competition policy, and they seek the use of coercive WTO legislation to prevent the disposal of surplus agricultural commodities as food aid. Current Uruguay Round food aid guidelines are contrasted with the most recent Doha Development Agenda proposals, and the prospective effectiveness of new rules is assessed. Food aid rules will be difficult to enforce within the WTO’s Dispute Settlement Understanding. Also, exogenous policy changes in donor countries are reducing the relevance of rules that target food aid as a means of surplus...

Valuation Methods for Environmental Benefits in Forestry and Watershed Investment Projects AgEcon
Cavatassi, Romina.
The understatement or omission of the environmental costs and benefits associated with forest management options results in project evaluations and policy prescriptions that are less than socially optimal. The aim of this paper is to examine the full range of costs and benefits associated with forests, distinguishing between how these should, and actually are, included in economic analyses. The paper first describes the economic analysis undertaken in the project evaluation procedure of the World Bank. The second section deals with all costs and benefits that typically occur in forestry projects. Costs and benefits are classified as on-site private, on-site public or global according to their nature and area of impact and according to the Total Economic...

Baseline Determination at Government Discretion: Multi-Project Baselines for the First Track of Joint Implementation? AgEcon
Michaelowa, Axel; Schmitz, Simon.
The "first track" of Joint Implementation under the Kyoto Protocol gives host and investor countries total freedom in choosing a baseline for a project reducing or sequestering greenhouse gases. This is due to the fact that an overly generous granting of emission credits leads to a corresponding reduction of the host country's emission budget. Standardised, multi-project baselines can reduce transaction costs, especially in relatively homogeneous sectors such as electricity production or landfill methane collection. Host countries need capacity to calculate such baselines which currently does not exist. "Boundary organisations" can bridge the gap between technical analysis and strategic considerations. Interviews with government officials and other...

ROLNICTWO OBSZARÓW GÓRSKICH BAWARII PRZYKŁADEM DLA KARPAT POLSKICH? STUDIUM PORÓWNAWCZE AgEcon
Sroka, Wojciech; Pieniadz, Agata.
Niniejsze opracowanie przyjmuje formę analizy porównawczej i przedstawia wyniki badań opinii ekspertów na temat stanu oraz kierunków rozwoju obszarów wiejskich i rolnictwa w gminach górskich położonych na terenie Karpat Polskich i Alp Niemieckich. Badania wskazują, iż rolnictwo oraz obszary wiejskie subregionu karpackiego wkracza powoli na drogę rozwojową, którą rolnictwo subregionu alpejskiego ma już w pewnym sensie za sobą. Wydaje się, iż krótki okres stosowania WPR nie spowodował w subregionie karpackim wyraźnych zmian strukturalnych. Rolnictwo Alp Niemieckich jest lepiej dostosowane do specyficznych warunków produkcji rolniczej oraz jest w stanie zapewnić odpowiednie dochody ludności rolniczej. Świadczy o tym chociażby wyższy odsetek rodzin...

Distribution of Agricultural NRAs across Countries and Products, 1955-84 and 1985-2007 AgEcon
Anderson, Kym; Croser, Johanna L..
The global database developed as an integral part of the World Bank's research project on Distortions to Agricultural Incentives, which is publicly available at www.worldbank.org/agdistortions, provides around 30,000 estimates of nominal rates of assistance to agricultural industries (NRAs) and associated consumer tax equivalents for 75 countries that together account for between 90 and 95 percent of the world’s population, farmers, agricultural output and total GDP. They also account for more than 85 percent of farm production and employment in each of Africa, Asia, Latin America and the transition economies of Europe and Central Asia as well as all OECD countries. More than 70 products are included (an average of 11 per country), which represents around...

CDM Potential of Dairy Sector in India AgEcon
Sirohi, Smita; Michaelowa, Axel.
Among the co-operative mechanisms established under the Kyoto Protocol, the Clean Development Mechanism is the only one, which has the potential to assist developing countries in achieving sustainable development by promoting environmentally friendly investment from industrialized country governments and businesses. Although, apart from nuclear energy and deforestation avoidance, all other projects are eligible under CDM, so far, the CDM projects have largely been confined to industrial sector and agricultural sector, in general has been left out. To assess the issues and opportunities presented by potential international markets for greenhouse gases offsets through the CDM and facilitate implementation of CDM in India, a National Startegy Study on CDM is...

Waterfowl Harvest Benefits in Northern Aboriginal Communities and Potential Climate Change Impacts AgEcon
Krcmar, Emina; van Kooten, G. Cornelis; Chan-McLeod, Ann.
Migratory waterfowl are important to the diets of residents in Canada’s northern communities. Contrary to recreational hunters, indigenous peoples have rights to harvest wildlife for subsistence needs without permits. As a result, migratory waterfowl are an important component of diets of Aboriginal peoples in northern Canada, substituting for expensive beef transported from the south. Wild geese and duck provide many benefits to native people, including improved nutrition and health. In this paper, scaled-down data from global climate models are used in a wildlife model to project potential migratory waterfowl abundance in the Northwest Territories for three future periods up to 2080. The models project potential future harvests of geese and ducks by...

Farm Productivity and Market Structure: Evidence from Cotton Reforms in Zambia AgEcon
Brambilla, Irene; Porto, Guido G..
This paper investigates the impacts of cotton marketing reforms on farm productivity, a key element for poverty alleviation, in rural Zambia. The reforms comprised the elimination of the Zambian cotton marketing board that was in place since 1977. Following liberalization, the sector adopted an outgrower scheme, whereby firms provided extension services to farmers and sold inputs on loans that were repaid at the time of harvest. There are two distinctive phases of the reforms: a failure of the outgrower scheme, and a subsequent period of success of the scheme. Our findings indicate that the reforms led to interesting dynamics in cotton farming. During the phase of failure, farmers were pushed back into subsistence and productivity in cotton declined. With...

Explaining Growth in Dutch Agriculture: Prices, Public R&D, and Technological Change AgEcon
Jongeneel, Roelof A.; Ge, Lan.
This paper analyzes the sources of growth of Dutch agriculture (arable, meat, and dairy sectors). Because the time series data (1950-1997) are non-stationary and not cointegrated, it is argued that a model estimated in first differences should be used. Estimated price elasticities turn out to be very inelastic, both in the short-run and the long-run. The direct distortionary effect of price support has therefore been rather limited. However, price support has an important indirect effect by improving the sectors investment possibilities and therewith the capital stock. Public R&D expenditure mainly affected agriculture by contributing to yield improvement therewith favoring intensification of production.

Productivity, Geography, and the Export Decision of Chilean Farms AgEcon
Echeverria, Rodrigo; Gopinath, Munisamy.
This article analyzes the export participation of Chilean farms and the relative importance of farm-specific and geographic characteristics in this decision. An export behavior model is estimated using data on 8,284 Chilean farms and a two-stage conditional maximum likelihood procedure. Farm efficiency has a relatively stronger effect than the combined effect of geographic characteristics in increasing the probability of export participation. Farms with skilled (managerial) labor and in regions with higher human capital also have a relatively higher probability of producing for the export market. However, for geographic characteristics to positively affect export participation, farms must achieve a minimum level of efficiency.

Marketing Underutilized Plant Species for the Poor AgEcon
Gruere, Guillaume P.; Smale, Melinda; Giuliani, Alessandra.
Underutilized plant species are defined as agricultural or non-timber forest species that are locally abundant in developing countries but globally rare. Scientific information about them is scant and their use is currently limited relative to their economic potential. Some are potentially high-value crops and they all contribute to agricultural biodiversity and the livelihood of the poor. Despite a growing body of scientific literature on underutilized species, to our knowledge, agricultural economics literature has contributed little to the understanding of how to commercialize these crops of plant products successfully. In this paper we first define what economic factors characterize underutilized plant species. Our classification of species is based...
