Latest developments in investment analysis offer a number of valuable insights into how to evaluate investment opportunities encountering the weaknesses of net present value criterion. More specific, irreversibility, uncertainty and the choice of timing are conditions that net present value does not include but they alter the investment decision in critical way. Employing contingent claims analysis in tangible investments several assumptions made by discount cash flow method are concerned and better assessment results can be derived. In this work, an attempt is made to apply real options methodology in agricultural investments. Many agricultural investors face a growing uncertainty environment with high sunk investments and net present value criterion has been extensively used that may be lead to incorrect decisions. Both discount cash flow method and real options approach are employed to evaluate the effectiveness of a new technology project under uncertainty returns in agriculture. Discount cash flow approach indicates that the adoption of a new technology project under uncertainty is feasible while real options approach differentiates the results. The corollary is that real options approach can be proved conducive in assessing projects with uncertainty and irreversibility and it can furnish a new way of examining agricultural investment decisions.

New policy measures have studied and introduced to transform Europe’s agriculture into a more environmental friendly agriculture. Adopting environmental friendly production systems involves risk and uncertainty and to overcome this well designed policy schemes are required. This study attempts to examine the effects of income variability upon the decision on adopting or not environmental friendly production systems in order to evaluate the organic financial incentives to farmers by introducing the real options methodology. The real options procedure revealed that the investment in environmental friendly production systems must be postponed and the option of investment must be kept alive until the expected returns are high enough to offset the risk and uncertainty. Therefore, policy makers have to reconsider the current financial incentives if they want faster adoption of sustainable production systems.

To assess the performance of a farmer and to identify best practice among a group of farmers, the assumption is often made that all farmers maximize profits and thus share the same business goals. However, performance differs due to personal characteristics, objectives and strategies. A survey carried out among 73 Belgian dairy farmers revealed that for only 34% of the farmers ‘profit maximization’ is a primary objective. A regression analysis revealed that self-declared profit maximizers only obtained a higher farm income per liter, not per labour unit. Through cluster analysis, four main groups of farmers were found with similar objectives and management ideas:
(A) risk-taking and progressive cow farmers,
(B) riskaverse and progressive labour savers,
(C) risk-neutral and relatively conservative profit maximizers and
(D) risk-averse and conservative cow farmers.
Gross margin per liter was highest for the labour savers. Other performance parameters were higher for cluster B only compared to cluster D. Scale economies were found for all performance parameters except for gross margin per liter.

This paper examines the influence of animal premiums under the CAP beef and ewe regime on beef and sheep meat farming in the Netherlands concerning instruments like stock density limits, quota on premium rights and premium payments. On the basis of econometric models, equations are estimated for beef cows1, bulls and ewes. Then, the impacts of the different policy instruments on the stocks are decomposed. At last, prospects of Agenda 2000 on the Dutch beef and ewe sector are calculated up to 2010. For policy makers, the study offers information on the effectiveness of animal premium instruments to manipulate beef and sheep meat production. For Dutch farmers, the study offers information to what extent premium instruments might influence the decision to incline or reduce their stocks.

This paper analyses the impact of adopting or rejecting genetically modified GM crops in the EU, taking into account the European Union's Common Agricultural Policy (CAP). In this paper the productivity impact of GMs differs across crops, as it takes factor biased technology change into account. The transfer of knowledge across countries is modelled as a process of endogenous knowledge spillovers. Analyses with a multi-region applied general equilibrium model shows that the CAP protects farm income and production from not adopting GM crops in the EU but has costs in terms of welfare. The EU will forgo substantial benefits if it banned GM imports.

Proposals for agricultural trade reform put forward by the main protagonists remain far apart, with little sign of convergence. In an attempt to progress the negotiations towards a successful outcome, the chairman of the WTO Committee on Agriculture has proposed a compromise. The alternative proposals by the United States, the European Union and the WTO are analysed with the Agricultural Trade Policy Simulation Model, a static, multi-commodity, multi-region, partial equilibrium trade model. The estimated annual global welfare gains are $26 billion, $12 billion and $17 billion respectively. Least developed countries, as a group, gain from the US proposal but are made worse off under the WTO and EU proposals. Furthermore, in the best case many individual countries experience welfare losses. However, all countries enjoy increased export revenues and tariff revenues hold up quite well under the two less stringent proposals.

Milk producers in virtually every OECD country, and in many non-OECD countries as well, benefit from government interventions. Indeed, government support and protection for milk producers is more widespread than for any of the other commodities for which the OECD calculates producer subsidy equivalents. The purpose of the analysis reported in this paper was to investigate the relative market effects of these two varieties of government intervention in milk pricing: 1) interventions through trade measures applied to dairy products and 2) discriminatory pricing arrangements. Which kind of policy creates ‘dollar-for-dollar’ the greater effects? This paper shows the answer to that question is – it depends. Neither economic theory by itself, nor economic theory combined with ‘plausible’ ranges of numerical values for key parameters is enough to say definitely one way or another. In some plausibly real-life situations domestic milk pricing arrangements can be, at the margin, more distorting than explicit trade measures. The key determining parameters include the usual suspects – the relative elasticities of fluid and manufacturing milk demand, as well as initial price gap between fluid and manufacturing milk provided by various measures and the proportion of domestic milk production used to manufacture tradable dairy products.

Is it feasible to increase income and generate employment in the context of a traditional labour intensive rural industry with strong linkages to an agriculturally backward economy? In order to address this issue, primary data from four villages of Peruvian North Sierra was used. The case of the hat making activity, employing exclusively family labour, purchasing the main input (straw, paja de palma) from Ecuador, and with consumers concentrated on villages and small towns, was investigated. The analysis was made at the market level. Considering the context of a self-employment activity, a theoretical framework was developed to explain the determinants of labour demand, input demand, hat output and labour return. Demand and supply constraints to the expansion of hat making activity were found. Important differences in the value of labour marginal product across the sample were identified. These were mainly associated with the use of varied input quality. Growth based on local demand would not be viable given falls in consumer incomes - mainly farmers - and expected changes in consumer preferences; therefore the growth motor would rest more in market expansion and product diversification to urban consumers.

Книга «Пространственная экономика – города, регионы и международная торговля» рассматривает экономику с точки зрения экономической географии – через определение, где и почему развился тот или иной вид экономической деятельности. Это новая глава в развитии экономической географии. Авторами предлагаются новые методы для моделирования, получившие начало в теориях экономического роста, международной торговли и промышленной организации. Более того, через многофакторный анализ «эффект повышения отдачи - транспортные издержки - движение продуктивных факторов» открываются возможности для новой экономической географии при решении проблем в городской, региональной и международной экономике.

Sustainable agriculture implies the exploitation of natural resources now, without compromising the natural resources stocks for the future generations. In the context of the paper, agricultural sustainability takes place at the interface between agriculture and the environment. The focus is on the interplay between farming systems and agrienvironmental policies. Agricultural policies have major impacts on soil and water quality and on bio-diversity. Support commodity price policies have lead to serious problems of water pollution; high levels of soil erosion; nitrate losses and lost of biodiversity. The semi decoupeted income support policies and the introduction of the agrienvironmental schemes under the 1992 CAP reform were the first attempts to correct the negative aspects of the production-orientated policies. For the first time farmers were regarded as countryside and landscape keepers and as environmental conservationists. Under the 2000 Agenda similar emphasis was given to the sustainability of agriculture. The objective of this paper is to evaluate the impact of the different agri-environmental policies on typical farming systems and consequently their effects on water pollution, soil erosion and bio-diversity/landscape. A bio-economic model, integrating a mathematical programming model and crop growth simulation model, is applied to estimated the changes in the levels of nitrogen leaching and soil erosion, and in the degree of bio-diversity under the current and proposed agricultural policy scenarios. The following farming systems are studied: dry land cereal farming systems (intensive and extensive), livestock and irrigated farming systems using conventional and conservation farming technologies. The results show The results show that the main changes on water pollution, soil erosion levels and biodiversity are mainly due to changes in price and arable compensatory payments. The agri-environmental measures are more important as farm income source than as a policy instrument to influence environmental parameters.

One of the common strategies in rural development programmes is to support the adoption of new on-farm activities. The rationale behind this is that farm diversification is a way to assure an appropriate level of income for the farmers. Through interviews with 49 relatively small farmers, the possibilities for diversification as a survival strategy are assessed. The analysis is mainly based on a classification of development pathways by Bowler (1992). Few forms of diversification appear to be successful as a survival strategy in case of economic problems. Only off-farm employment seems to be effective in this respect. The introduction of new activities on marginal farms is hampered by lack of financial and human capital. On the other hand, diversification is often found on small farms without financial problems. This is an indication that on-farm diversification is able to stabilize the household income and to avoid financial problems when it is used as a preventive strategy.
