A comparative analysis between (32P) and digoxigenin-labelled single-copy probes for RFLP detection in wheat Inra
Lu, Y.H.; Merlino, M.; Isaac, P.G.; Staccy, J.; Bernard, M.; Leroy, P..
Le polymorphisme de longueur des fragments de restriction (PLFR) a été largement utilisé pour l’établissement de cartes génétiques des plantes et pour diverses études génétiques. Bien qu’elle présente d’intéressantes potentialités et perspectives pour les sélectionneurs, l’utilisation des éléments radioactifs dans cette technique a limité son application en routine. Nous avons modifié et amélioré une des méthodes non radioactives commercialement disponibles, le marquage à la digoxigénine (Boehringer Mannheim), pour l’analyse d’un génome polyploïde tel que le blé. Les résultats obtenus sont comparables à ceux de la méthode radioactive. Les procédures expérimentales sont décrites en détail. Cette méthode non radioactive devrait faciliter tous les types...

Agriculture, Structural Change and Socially Responsible Development in China and Vietnam AgEcon
Tisdell, Clement A..
The gradualism of economic reforms in China and Vietnam (especially in China, which has led the way in this regard) has been commented on favourably by many analysts studying transitional economies. Early market reforms in China and Vietnam were constrained by political considerations and consequently, began in agriculture and in China’s case, in rural areas with the development of town-and-village enterprises as well. It is argued that at the time when the reforms began, they were socially responsible. However, they have created a legacy which has resulted in agricultural land disputes and many town-and-village enterprises now face new economic challenges resulting in social conflict as the structure of China’s economy alters and greater market...

Economic Growth and Transition in Vietnam and China and its Consequences for their Agricultural Sectors: Policy and Agricultural Adjustment Issues AgEcon
Tisdell, Clement A..
Secondary data are used to discuss and compare the consequences for agriculture of economic growth and transition in Vietnam and China. It is found that China and Vietnam have experienced similar adjustments in their agricultural sectors and face at this time, similar agricultural policy problems. China began its economic reforms in 1979 and Vietnam followed in 1986. Since then both countries have experienced rapid economic growth, falling poverty rates and significant rises in per capita income. At the same time, substantial restructuring of their economies has occurred, a feature of which has been a decline in the relative contribution of agriculture to total employment and output. These changes are outlined. Significant changes have also occurred within...

EMBEDDED INSTITUTIONS AND THE PERSISTENCE OF LARGE FARMS IN RUSSIA AgEcon
Koester, Ulrich; Petrick, Martin.
Differences in farm structures between Russia and western market economies can hardly be made consistent with the neoclassical textbook idea of a technologically determined farm size operating in a perfect market environment. The main aim of the paper is to identify embedded institutions that provide an explanation for the persistent differences. It is shown that these institutions vary widely across countries. We argue that the historical contingency of a patrimonial society that is both hierarchical and egalitarian also has an important bearing on the current persistence of large farming structures in Russia. The cultural beliefs based on this contingency explain the relative absence of entrepreneurial attitude in the rural society, the lack of trust in...

ENDOGENOUS INITIATIVES AS A CHANCE TO IMPROVE RURAL LIVELIHOOD? RESULTS OF A CASE STUDY IN BALTOW, SOUTH-EASTERN POLAND AgEcon
Gramzow, Andreas.
Polish rural areas, compared to other EU-25 member states, still show a high agricultural employment due to a lack of job opportunities in other rural economic sectors. In particular, in South-eastern Poland the shut down of heavy industry companies in the early 1990s left many rural inhabitants only with small incomes from their peasant farms or pensions. In the commune Ba³tów (South-eastern Poland) in order to counteract these developments, local development associations and a regional partnership undertook initiatives to stimulate the regional economy by creating a tourism infrastructure. This paper presents a case study, conducted in Ba³tów, which analyses local problems, development chances, and experience with local endogenous initiatives. The main...

EXPERIENCE WITH ENDOGENOUS RURAL DEVELOPMENT INITIATIVES AND THE PROSPECTS FOR LEADER+ IN THE REGION "DOLINA STRUGU", POLAND AgEcon
Gramzow, Andreas.
This paper presents the results of a case study of local economic development in Dolina Strugu, Podkarpackie voivodship, Poland. Its aim is to analyse local development problems and chances, to investigate the potential of endogenous initiatives to support economic development, and to examine the prospects for an implementation of the EU's initiative Leader+. The case study primarily relies on interviews conducted with local government authorities, NGOs, business owners and farmers in summer 2005. The hitherto unsatisfactory income situation in agriculture has been particularly precarious for the region because two thirds of the people in working age are employed in agriculture and alternative job opportunities are mostly absent. To respond to these...

FARM INVESTMENT, CREDIT RATIONING, AND PUBLIC CREDIT POLICY IN POLAND: A MICROECONOMETRIC ANALYSIS AgEcon
Petrick, Martin.
The aim of this paper is to empirically analyse the effects of governmentally promoted credit access on the investment behaviour of credit rationed farmers. This is done by specifying an empirical investment equation which is estimated on a cross-sectional sample of Polish farm household data. In contrast to conventional neo-classical investment models, the investment equation contains the financial variable long-term credit access, which plays the central role in this study. The econometric analysis is used to analyse the determinants of credit access and estimate the marginal effect of credit on investment, which in turn provides the key information for policy evaluation. The results suggest that access to subsidised credit has a significant role in...

Institutional Change in East German Water Management Systems AgEcon
Schleyer, Christian.
Like in many fen land regions in East Germany, long-standing intensive arable farming -enabled by reclamation - has caused soil deterioration and high water runoff in the Schraden region. More than ten years of economic and political transformation that followed the breakdown of the socialist regime has worsened the situation and even added new problems. The visible consequences are droughts in the summer, waterlogged plots in the spring, and worn-down water management facilities that operate in an uncoo rdinated or unautho rized way. Given the local public good character of so me features of the fen land, the common-pool character of the intermittently scarce resource water within the ecosystem, and the conflicting interests of regional stakeholders, it...

Land Reform and Development of Agricultural Land Markets in Russia AgEcon
Lerman, Zvi; Shagaida, Natalya.
Russia has experienced dramatic changes in land ownership and tenure since 1991: agricultural land has been largely privatized, individual landowners now have legal rights to most agricultural land in the country, and prohibitions on buying and selling of land have been recently removed. The necessary pre-conditions for the development of agricultural land markets have been met and we are beginning to witness transactions that involve individual landowners, and not only the state. Further development of the land market is circumscribed by the inadequacy of the administrative and technical infrastructure. The paper discusses the evolving legal framework for land reform, considers the impacts on privatization and ownership structure of agricultural land, and...

LOCAL PARTNERSHIP AS AN INCUBATOR FOR RURAL DEVELOPMENT: THE CASE OF DEBRZNO, NORTH-WESTERN POLAND AgEcon
Gramzow, Andreas.
Since the beginning of the 1990s, the gap in economic development between rural and urban regions in Poland has continuously grown. Increasing income disparities and the lack of job opportunities have already led to an outflow of young people out of and an increasing obsolescence in rural areas. As successful examples in different Polish regions show, endogenous initiatives may have a lasting impact on the economic development of rural areas and are able to counter the mentioned effects. This paper presents the results of a case study which analyses endogenous initiatives in the commune Dêbrzno, Pomorskie voivodship, Poland. The case study results primarily rely on open interviews conducted with inhabitants, representatives of the local government, and...

Marketing, Co-operatives and Price Heterogeneity: Evidence from the CIS Dairy Sector AgEcon
Sauer, Johannes; Gorton, Matthew; White, John.
Drawing on survey data, this paper identifies the determinants of variations in farm gate milk prices for three CIS countries (Armenia, Moldova and Ukraine). We apply a multi-level modeling approach, specifically a bootstrapped and selectivity bias corrected mixed-effects linear regression model. The analysis suggests three main strategies for farmers to improve the price received for their output: consolidation, cooperation and stable supply chain relationships. While selling through a marketing cooperative has a significant and positive effect on farm gate milk prices, the majority of non-members are reluctant to join. The size of dairy operations, trust and contracting also impact positively on the prices received by farmers. Policy implications are...

Marketing, cooperatives and price heterogeneity: evidence from the CIS dairy sector AgEcon
Sauer, Johannes; Gorton, Matthew; White, John.
Drawing on survey data, this paper identifies the determinants of variations in farm gate milk prices for three CIS countries (Armenia, Moldova and Ukraine). We apply a multi-level modeling approach, specifically a bootstrapped mixed-effects linear regression model. The analysis suggests three main strategies to improve the price received by farmers for their output: consolidation, competition for output and stable supply chain relationships. In Armenia and Ukraine selling through a marketing cooperative has a significant, positive, albeit modest, effect on farm gate milk prices. In all three countries studied, the size of dairy operations, trust and contracting also affect positively the prices received by farmers.

Measurement and Explanation of Technical Efficiency Performance in Ukrainian Agriculture, 1991-1996 AgEcon
Murova, Olga I.; Trueblood, Michael A.; Coble, Keith H..
The present study examines technical efficiency patterns in Ukraine’s crop sector for 1991-1996. The economic and policy environment in Ukraine has changed since reform began in 1991. Many policy changes have exerted offsetting economic pressures on efficiency. Enterprise privatization and the liberalization of prices and trade put upward pressure on technical efficiency, whereas start-stop land privatization efforts, unpredictable government intervention, and slow developments in the credit and labor markets put downward pressure on efficiency. We found that technical efficiency appears to have improved slightly over the 1991-1996 period, suggesting that the positive forces had more impact.

POLAND'S AGRICULTURE: SERIOUS COMPETITOR OR EUROPE'S POORHOUSE? SURVEY RESULTS ON FARM PERFORMANCE IN SELECTED POLISH VOIVODSHIPS AND A COMPARISON WITH GERMAN FARMS AgEcon
Petrick, Martin; Spychalski, Grzegorz; Switlyk, Michal; Tyran, Ewa.
The aim of this paper is to present an analysis of farm-level data collected in a survey of 464 Polish farms in 2000. Performance indicators of farms in three Polish voivodships are compared with farm accountancy data from two German Länder. The results show that Polish farms were much less profitable than their German counterparts. The gap in income levels is much higher between persons employed in the agricultural sector than between average working persons in the two countries. Living standards within the Polish farm sector decline from the north-west to the south-east. The analysis suggests that the lower profitability of farms is a consequence of pronounced structural deficiencies due to a quite unfavourable workforce-land ratio on Polish farms and...

Productivity and Efficiency of Corporate and Individual Farms in Ukraine AgEcon
Lerman, Zvi; Sedik, David J..
The paper presents a comparative analysis of the productivity of corporate and individual farms in Ukraine based primarily on cross-section data from a farm survey conducted by FAO in 2005. We calculate partial land and labor productivity, total factor productivity, and technical efficiency scores (using Stochastic Frontier Analysis) for farms of different organizational forms. Our results demonstrate with considerable confidence that, contrary to established convictions among the Ukrainian decision makers, the large corporate farms are not more productive than the smaller family farms. This finding is not restricted to Ukraine, as a similar result has been obtained by in Moldova, Russia, and the U.S. Policies encouraging a shift from large corporate farms...
