A theory-based graphical analysis of WTO’s trade liberalization policies (opening of close-economy to international trade and cuts in price-supports, import-tariffs and exportsubsidies) suggests that most of such policies would yield net social gains to the society, as a whole. The adverse effects and losses in producer surpluses of some of the policies would be balanced out by greater gains in consumer surpluses and vice versa. Losses in producer surpluses due to cuts in price supports and import tariffs are also expected to be partially subsided by reductions in export subsidies mainly granted by the USA and EU; hence, policies need to be enforced, not in isolation, but in a simultaneous fashion. Trade liberalization would help minimize control of individuals on trade, leave less room for individual policy makers, tax collectors and interest groups to exploit situations in their own interest and lead the economy to be run in accordance with the supply and demand forces based on the last lasting general tendency of human nature. This would help to achieve a sustainable and stable agricultural growth; however, more durable sustained growth would depend as how effectively trade liberalization is pursued and enforced the world over. Opening of closed economy for exportables, and withdrawal of export subsidies by foreign exporters would be proproducers and would directly contribute to poverty alleviation. Opening of economy for importables, withdrawal of price supports and tariff-cuts on imports would yield savings to consumers and would positively contribute towards poverty reduction.

Although there is broad agreement that well functioning land rental markets will play an important role to increase productivity and household welfare as agrarian economies develop, evidence from Africa on the actual performance and impact of such markets is limited. We use data from Uganda to test for differences in the performance of rental, as compared to sales markets and their evolution over time, based on a framework where markets are affected by differences in ability and imperfections in rural labor and capital markets.

We find that land markets are very active, that land rental but not sales markets transfer land to more efficient and relatively poor producers thereby providing an opportunity for the landless to access land, and that rental market activity has increased recently with economic growth. Despite land prices in some regions being above the net present value of land we find no evidence for sales markets leading to land concentration and conclude that, rather than imposing administrative restrictions, government should aim to improve access to alternative savings instruments.

This study investigated the efficiency and productivity change of a sample of food distribution units (MERCAs) in Spain over the 1.997-1.999 period, applying non-parametric frontier methodology in a sales efficiency framework. We specified a mean sales model composed of two blocks of variables, the production block, and the marketing management block. Then we applied output oriented DEA methodology to perform the efficiency analysis, also taking into account the overall efficiency decomposition into pure and scale efficiency. The Malmquist index was calculated in order to analyse the components of the productivity change.

The mean pure sales efficiency index was high, around 0.8, the mean scale index being 0,9. As appears from the results, six food distribution units were efficient, but some of the wholesale markets need to adapt their sales technology in order that their input bundle reaches a Most Productive Scale Size unit.

We found no evidence of technical change during the period considered, but concluded that a notable scale efficiency change took place during the studied period.

To summarise, we conclude that improvement in sales efficiency could be reached in the studied sector in both the pure and the scale efficiency.

In Rwanda for the past decade, rural households have lived with civil unrest and genocide, changing land laws, large population flows both into and out of the country, and climatic threats with droughts and floods. The illness and untimely death of prime age adults from a number of health problems (increasingly HIV/AIDS) adds to the stress of these households and has lasting effects on the ability of households to survive. In this research, the authors use household and member level survey data to increase understanding about what is happening in households with such shocks and how they may be different from other Rwandan rural households.

This research finds that households affected by adult illness and death strive to maintain their agricultural production, and work to avoid selling assets, yet some households appear to be in a downward spiral, losing assets and income earning potential. They rely heavily on social networks for labor and skills, but clearly these networks will be stretched beyond their means in any continuing epidemics. Female-headed households in particular struggle to find labor with neighbors or work more themselves. If special programs are developed for the affected families, focusing on increasing land and labor productivity fits into their own strategies. Since households with prime age death and disease appear to be similar to other Rwandan households in the poorest two quintiles, such programs would be beneficial to rural households in general, and possibly strengthen social networks through generalized agricultural and income growth.

Using a partial equilibrium model of world agriculture, we investigate the multilateral removal of all border taxes and farm programs and their distortion of world agricultural markets. These distortions have significant terms-of-trade effects. World trade is also significantly impacted by both types of distortions. Trade expansion is substantial for most commodities, especially dairy, meats, and vegetable oils. Net agricultural and food exporters (Brazil, Australia, and Argentina) emerge with expanded exports; whereas net importing countries with limited distortions before liberalization are penalized by higher world markets prices and reduced imports. The US gains significant export shares in livestock products and imports more dairy products. Without protection and domestic subsidies, the EU loses many of its livestock and dairy export markets.

This paper investigates the relationship between theft and poverty in rural areas. Following a disputed presidential election, fuel supply to the highlands of Madagascar was severely curtailed in early 2002, resulting in a massive -- if temporary -- increase in poverty. This situation constituted a natural experiment of the effect of poverty on theft. Using original survey data collected in June 2002 at the height of the crisis, we find that crop theft increases with poverty and that an increase in law enforcement personnel reduces cattle theft, a form of organized crime. Results suggest that theft is used by some of the rural poor as a risk coping strategy. Increased transport costs led to a rise in cattle and crop theft, suggesting that isolation raises crime.

Although there is increasing emphasis on targeting of improved technology towards poor and female farmers, few adoption studies assess the uptake of new practices by these groups in a comprehensive manner.

In this study, community members used the wealth ranking method to identify the different wealth groups in their communities, to determine each household.s wealth status, and to assess the association of wealth and different types of households with the planting of improved tree fallows, a practice for improving crop yields. There were no significant differences between the proportions of women and men planting improved fallows nor were there differences between single women and female heads of households who were married. There was some evidence of association between planting improved fallows and wealth. That 22% of the .poor. group and 16% of the. very poor. group were planting them suggests that there are no barriers preventing low-income households from doing so. Moreover, the proportion of females, poor, and very poor people planting improved fallows varied considerably among villages, suggesting that opportunities exist for increasing their use of the technology. Whereas the use of mineral fertilizer is strongly associated with high- income, male farmers, improved fallows appear to be a gender-neutral and wealth-neutral technology. Poor farmers appreciate improved fallows because they permit them to substitute small amounts of land and labour for cash, their most scarce resource. Finally, the high degree of consistency among different key informants in classifying households among wealth groups confirmed the effectiveness and accuracy of the wealth ranking exercise.

The paper examines the impact of local institutions on development and poverty in the rural areas of India. Recent research on the role of institutions on the path of economic development indicates the importance of both "macro" and "micro" institutions including local institutions. The study finds a large number of both formal and informal local institutions in the surveyed villages, and a substantial degree of interaction of the households with the institutions. These include both formal institutions such as service cooperatives and dairy cooperatives, as well as informal institutions such as savings groups, community associations and labour groups. The study finds that apart from the standard factors included such as land, capital and labour, the presence and membership in local institutions plays a significant role in explaining the variation in household incomes and gain in capital assets over time.

Savings/ micro-credit groups, and dairy cooperatives are found to be particularly important. Further, membership in these institutions is not found to be related to high asset levels or high caste - it is often inversely so. This indicates a stronger developmental role. Recorded opinions of the households supports the findings on the impact and beneficial role of local institutions. The study confirms that institutions do matter, and that local institutions can and do make a significant contribution in helping development in the rural areas, especially so for the lower income groups.

In many industrialized countries, the grocery-retailing sector exhibits a strong and increasing market concentration. Hence, it is important to understand retail pricing for many questions related to market power in the marketing chain and to agricultural and food policies. We analyze intertemporal pricing of grocery retailers in Germany with a large set of scanner data for processed foods. In theory, food prices could be rather variable, e.g. due to fluctuating commodity prices in a competitive world, or rather rigid, e.g. due to price adjustment costs. We elaborate that retail sales are crucial and raise food price variability at the points of sale. Despite this, prices are rather rigid and often do not change for many weeks. Moreover, pricing strategies for identical brands vary strongly across retailers. Retailers seem to have differential pricing strategies and, thus, market power. This casts substantial doubt on the assumption of a competitive price transmission in the marketing channel underlying most analyses in agricultural economics.

The objective of this paper is to develop a tractable approach for recovering and quantifying all sources of TFP changes (namely, technical change, changes in technical and allocative efficiency, and scale economies) from the econometric estimation of an input distance function which also fully describes the production technology. The proposed theoretical framework relies on Bauer’s TFP decomposition framework and the duality between input distance and cost functions. Hence, instead of using a system approach to estimate a cost frontier, all necessary information for decomposing TFP changes are recovered from its dual counterpart.

The paper argues that current long-term projections of global meat and feed demand may underestimate future consumption patterns for mainly two reasons. First, they do not explicitly consider increased demand for protein foods of animal origin with rising incomes in some developing contries, and second they do not allow for changes in livestock technology, in particular feed demand. We then project the impact of both mechanisms to show the empirical relevance of our comments and suggest ready-to-use tools to consider them within standard projection models.

This paper is concerned with the impact of the BSE crisis in the UK and focuses on price transmission between retail and farm prices. From a theoretical perspective we show that market power has an effect on price transmission between retail and farm prices following a demand shock. The empirical results suggest that the impact of a food scare on farm prices to be more than double that of retail prices, the direction of this effect being consistent with the impact of oligopoly dominating the effect (if any) of oligopsony.

However, important in assessing the full impact of a food scare is the ability of consumers to switch into substitute products. This is also evident following the BSE crisis with the availability of substitutes contributing significantly to the overall impact on price adjustment.

Economic reforms have induced different output and productivity changes in Russia, China and the transition countries of Eastern Europe. The main objective of this paper is to analyze what has caused these differences in performance. We discuss how initial conditions and reform policy choices affect changes in property rights, production organization, terms of trade, and the liberalization of the economy. We analyze how these, in turn, have affected economic performance.

The hypotheses are tested by quantitative analysis. We conclude that it is a combination of both initial conditions and reform policy choices which has caused the differences in performance.

The demand for hedging against price uncertainty in the presence of crop yield and revenue insurance contracts is examined for two French wheat farms. The rationale for the use of options in addition to futures is first highlighted through the characterization of the first-best hedging strategy in the expected utility framework. It is then illustrated using numerical simulations. The presence of options is shown to allow the insured producer to adopt a more speculative position on the futures market. Futures are shown to be performing, in terms of willingness to receive. Options are weakly performing when futures markets are unbiased, while they are more performing when futures markets are biased.
