Reductions in transport and transaction costs are expected to have a major effect on the functioning of food markets in developing countries. For many developing countries, this is a relevant issue as it may have important consequences for the food markets in urban and rural deficit areas. A partial equilibrium model is presented to analyze the effects of reduced costs on cereal price formation, inter-regional cereal trade, and farmers' and traders' storage strategies for the case of Burkina Faso. Our results show that the high expectations with regard to the direct effects of cost reductions on food prices and food availability require some nuance. First, the effects of even a huge reduction of transport costs only will be small. Secondly, an element which is often neglected is that constructing a road between two cities may have unintended negative consequences on the competitive position of farmers and traders in other regions. Finally, it is concluded that only if transport and transaction costs are reduced simultaneously, both consumers and farmers will benefit significantly.

The deep transformations brought about by the progressive and steady commitment of Romanian economy to the market economy have determined, among others, the modification of the role and status of rural household in the economic activity. Rural household changed from a simple participant, constrained to act in a certain way under a centralised, equalising and levelling system during the communist period, to a participant that carries out its activity in a competing environment in which initiative, creativity and efficiency are defining elements. Based on field surveys conducted at national level, the present paper intends to identify the evolution of economic behaviours specific to rural households under the influence of agricultural policy measures in the period 1997-2000. The conclusions of this study reveal that in this period, most of rural households operated under a subsistence system, according to an economic rationality in which market economy mechanism are lacking. However, the economic picture is far from being a homogeneous one: the emergence of a nucleus of agricultural entrepreneurs, i.e. those who assume the risk of shifting from subsistence to competitive agriculture, those who are trying to turn the peasant household into a farm managed on the capitalist principles, has induced new economic behaviours in the rural communities.

The study evaluates the efficiency of government intervention using a vertical structured model including imperfectly competitive agricultural input markets, the bread grain market, and the imperfectly competitive food industry. To test for policy efficiency the actually observed bread grain policy is compared to a hypothetical efficient policy. To account for the sensitivity of the results in regard to the model parameter values computer-intensive simulation procedures and surface response functions are utilized.

Since the early 1990s, researchers have routinely used count data models (such as the Poisson and negative binomial) to estimate the demand for recreational activities. Along with the success and popularity of count data models in recreational demand analysis during the last decade, a number of shortcomings of standard count data models became obvious to researchers. This had led to the development of new and more sophisticated model specifications. Furthermore, semi-parametric and non-parametric approaches have also made their way into count data models. Despite these advances, however, one interesting issue has received little research attention in this area. This is related to the fast decay process of the dependent variable and the associated long tail. This phenomenon is observed quite frequently in recreational demand studies; most recreationists make one or two trips while a few of them make exceedingly large number of trips. This introduces an extreme form of overdispersion difficult to address in popular count data models. The major objective of this paper is to investigate the issues related to proper modelling of the fast decay process and the associated long tails in recreation demand analysis. For this purpose, we introduce two categories of alternative count data models. The first group includes four alternative count data models, each characterised by a single parameter while the second group includes one count data model characterised by two parameters. This paper demonstrates how these alternative models can be used to properly model the fast decay process and the associated long tail commonly observed in recreation demand analysis. The first four alternative count data models are based on an adaptation of the geometric, Borel, logarithmic and Yule probability distributions to count data models while the second group of models relied on the use of the generalised Poisson probability distribution. All these alternative count data models are empirically implemented using the maximum likelihood estimation procedure and applied to study the demand for moose hunting in Northern Ontario. Econometric results indicate that most of the alternative count data models proposed in this paper are able to capture the fast decay process characterising the number of moose hunting trips. Overall they seem to perform as well as the conventional negative binomial model.and better than the Poisson specification. However further investigation of the econometric results reveal that the geometric and generalised Poisson model specifications fare better than the modified Borel and Yule regression models.

This paper focuses on the impact of mitigating greenhouse gases (GHG) on agricultural trade. In particular, the paper assesses the impact on New Zealand (NZ), which is highly reliant on agricultural trade, with a high percentage of its total GHG emissions are originating in the agricultural sector. The paper also analyses the impact of mitigation strategies in the European Union (EU), which has a low proportion of GHG coming from agriculture, a highly protected agriculture sector, and is a major market and competitor for NZ. Results from a partial equilibrium trade model, the LTEM, show clearly that while these mitigation strategies achieve the goal of GHG reduction, producer returns are also negatively affected. The value of these changes in emissions are then calculated, based on US$15/tonne of carbon dioxide (CO2), and producer returns adjusted for this. Although this value of CO2 goes some way towards offsetting the reduction in producer returns, it would need to be considerably greater in order to provide any significant compensation.

Rapid developments in E-commerce can bring efficiency in the food market system by cutting transaction costs. However, it can also bring a battleground between developed and developing countries and also within developed countries because the New Economy emphasizes knowledge-based labor practices and low-skilled workers of trading nations compete for a shrinking need for their services. An Input-Output model is used to examine the effects on high-skilled and low-skilled worker demand, particularly in food and agriculture. The food and agriculture industries are significant employers of low-skilled labor. Food and agriculture trade has reduced low-skilled labor demand in the United States.

In this paper, we consider the extent to which there has been genuine restructuring of Russian corporate farms by oblast and attempt to explain the various levels of farm restructuring by oblast.

To do this, we measure the average level of technical efficiency of crop production on corporate farms by oblast over the period 1991-1995 and the change in technical efficiency by oblast over that period. We find that many of the producing regions that were relatively efficient before the reforms have maintained this status since reforms began. However, the most inefficient regions have become even more inefficient. We also find that variations in efficiency by oblast can be explained by economic and institutional factors, including shocks in relative prices, average farm size, the extent of state marketing channels, the degree of privatization, subsidy levels, and movement towards crop specialization.

A non-linear optimization model which maximizes total Ecuadorian social welfare, defined as the sum of Consumers’ and producers’ surpluses for the four major crops (corn, bananas, rice and African palm) is developed to evaluate the tradeoff between welfare and environmental degradation in Ecuador. It was found that a total welfare loss of US$122 million (a 11 percent reduction - from US$ 1.112 billion to US$ 989.66 million) would be expected from a 30 percent reduction in the total pesticide load on the environment in the production of the four major crops. The distributional impacts of the welfare loss were found, however, to be significantly skewed toward the loss of consumers’ surplus. Specifically, a 30 percent reduction of total pesticide load on the environment would result in a reduction of 3.86 percent of producers’ total surplus while consumers would be expected to loose 19.46 percent of their total surplus.

The paper examines the interlinkages between population pressure and poverty, possible impacts on household welfare and land management, and the consequent pathways of development in a low potential rural economy. A dynamic non-separable bio-economic model, calibrated using data from the Ethiopian highlands, is used to trace key relationships between population pressure, poverty and soil fertility management in smallholder agriculture characterized by high levels of soil degradation. Farm households maximize their discounted utility over the planning horizon. Land, labor and credit markets are imperfect. Hence, production, consumption and investment decisions are jointly determined in each period. The level of soil degradation is endogenous and has feedback effects on the stock and quality of the resource base. This may in turn influence land management choices. Under high population pressure, land becomes dearer relative to labor. This is likely to induce conservation investments, especially when conservation technologies do not take land out of production. When markets are imperfect, poverty in vital assets (e.g., oxen and labor) limits the ability or the willingness to invest in conservation and may lead to a less sustainable pathway. Boserup-type responses are more likely when (privately) profitable technologies exist and market imperfections do not limit farm-households' investment options.

In this paper we report on preliminary results of a research aimed to examine the content of farm animal biodiversity conservation actions currently under implementation in the European Union in the framework of EU Agenda 2000. In particular, we surveyed sixty-three Rural Development Plans (RDPs) set up in twelve countries in application of EEC regulations 1257/99 and 1750/99. Our analysis focused on endangered breeds of six major livestock species included in the RDPs. This analysis, which is based on the comparison with the indicator’s status of the DAD-IS FAO database, allowed to identify priorities in conservation efforts in each country, and estimate the level of expected public expenditure needed to ensure the moving of breeds from at-risk (of extinction) status to not-at-risk status over the period 2000-2006.

The agricultural sector in Central and Eastern Europe (CEE) is confronted by two huge problems simultaneously: transition processes and sustainability. Institutions are very important for both these problems. The purpose of this paper is to make clear that the institutional setting is very important, and to give insight into the initial situation of institutions for sustainability and transitions. For this purpose we carried out surveys in CEE with questions about government performance, institutional environment, government structures and social capital. There is strong relationship between the determinants of good government performance in general and those for good government for realizing sustainable agriculture. However, besides formal rules, the informal rules of the institutional environment and social capital are also very important for realizing of sustainable agriculture. Results of surveys show that these institutional elements and the level of social capital are different in the countries of CEE, and have to be developed. Knowledge of government performance, institutional environment and social capital is a necessary condition for developing more suitable governance structures for realizing sustainable agriculture.
