Plant breeders face a unique appropriation problem – plants are reproducible, genetic information is heritable and seeds can be multiplied. The paper uses indicators of varietal age as a proxy for durability to examine strategies of planned obsolescence. Using wheat breeding in the UK, evidence of strategies of planned obsolescence is confirmed. This is then corroborated with evidence of tendencies towards increased proliferation of varieties on the market and breeding strategies that focus on incremental productivity improvements (i.e. increased efficiency) and narrow and limited disease resistance (i.e. reduced durability).

Estimated rates of return to research are distorted by problems of attributing the credit for particular research results, or for particular research-induced productivity increases, to research expenditures undertaken at different times, in different places, and by different agencies. A comprehensive assessment of the evidence from past economic evaluations of the returns to agricultural R&D indicates that studies generally report high rates of return, with enormous variation among studies, but that much of this evidence has been tainted by inadequate attention to attribution problems. br>
This paper raises these concerns in a general way, and illustrates their importance with reference to two particular types of attribution problem. First, we consider the problem of accounting for locational spillovers in attributing varietal improvement technology among research performers, using U.S. wheat varieties as an example. Second, we consider the temporal aspects of the attribution problem using the specification of research lags in econometric models to illustrate the problem of attributing aggregate productivity gains to research expenditures at different times.

In the Mid-Term Review (MTR), the European Commission proposed a series of changes to the Common Agricultural Policy (CAP). An important part of these changes was significant decoupling of support payments from production. In this paper, a partial equilibrium model of the EU agricultural sector is used to estimate the potential impacts of the MTR proposals on EU and world agricultural markets over the period 2004-2009. Effects of the MTR proposals are evaluated by comparing estimated outcomes under the proposals to those that would result under a current-policy baseline. The changes that are made in the MTR have the effect of reducing the production of the major commodities by varying amounts based on the importance of payments in production and the degree to which these payments are currently production inducing. For example, total area harvested for nine major crops falls by about 2 percent under the MTR proposals. In the livestock sector, however, where current payments are strongly coupled and form a large part of producers’ income, the reductions in production are projected to be more significant.

This article presents and analyses the impacts of the EU sugar policy. Particular attention is given to the modelling of the quite complex policy and the calibration of the global general equilibrium model at the member state level. Two scenarios are analysed, namely a reduction in the intervention price of sugar and the sugar quota. It is found that the economic impacts of the two scenarios are quite different in terms of the effects on European production and trade in sugar as well in terms of efficiency. The impacts for developing countries also differ considerably across the two scenarios.

This paper examines the extent of interregional integration of Russian food markets from different perspectives. Though food price levels in Russia are converging after the period of hyperinflation, remote regions like the Far East seem to be on a different price path. With regard to the interregional commodity flows, it could be shown that interregional transportation of grain is unlikely to have decreased significantly, if the figures are corrected for imports and feed use. But a cross-sectional regression analysis using differences between regional production and consumption revealed that regional surpluses as well as deficits for all products tend to diminish, which means that the Russian regions increasingly rely on their regional production and not on interregional trade.

This paper addresses the combination of environmental regulation and rural development using an integrated economic modelling approach. Specifically, the regional impacts of regulating livestock density at the farm level are analysed in a projected 2010 setting. This scenario is motivated by a concern for nitrogen loads on ground and surface water. The applied model framework includes a macroeconomic CGE-model, an econometric agricultural sector model and a local economic model, and consistent links have been established between these models. The analyses show that the largest relative economic impacts occur in the western parts of Denmark. This occurs in the agricultural sector, because the highest livestock densities are found in the western regions, but also at the general economic level, because agriculture is relatively important for the regional economy in these regions. However, the maximum absolute economic impact on the regional economies in terms of regional GDP is only around one per cent in the most affected region.

We have employed a simple model to analyse market regulation in a situation with multifunctional agricultural production, i.e., a public good produced jointly with a private good, and where there is imperfect competition in processing. We have analysed the impact on welfare of two archetype regulatory institutions formed to overcome the market imperfections. The institutions, a Regulatory Marketing Board and a Regulatory Marketing Cooperative, are both represented in the Norwegian agricultural market. Taking into account the cost of public funds, we find that the Board in general ensures the highest social welfare. The Cooperative does not replicate the Board solution unless restricted by a price cap and in combination with a production subsidy. If the restricted Cooperative is able to practise a higher degree of cost sharing than the Board, it may however produce the highest welfare.

Regulatory reform had its beginnings in the United States in the 1970s, and today it is taking place around the globe. One of the central questions for industrial policy is how to regulate firms with market power. Regulatory Reform tackles this important policy issue in two parts: it describes an analytical framework for studying the main issues in regulatory reform, and then applies the analysis to the British experience in four utility industries - telecommunications, gas, electricity, and water supply. Britain's utility industries, state-owned monopolies just ten years ago, offer a dramatic example of comprehensive reforms with parallels elsewhere: industries have been restructured, markets have been liberalized, and new regulatory methods and institutions have been created. The authors focus on common policy questions that arise in each industry while taking into account the considerable diversity between the industries and the different reform policies adopted. The analysis and experience in Britain's utility industries also provides a rich variety of issues concerning monopolistic and anticompetitive practices that are of interest for competition policy in general.

The paper aims at analyzing the potentials for reducing income risk and income variation for slaughter hog producers in Germany and Holland by participating at futures markets in Amsterdam or Hannover. The relative market and hedging efficiency for the Amsterdam stock exchange markets is tested and the optimal hedge ratio is derived for minimizing risk and variance of slaughter hog gross margins (income). Relative market efficiency and a significant impact of hedging on income risk and variance can not be rejected. The results show that the optimal hedge ratio is smaller for variance compared to risk minimizing hedging strategy.

An agreement between Norway and the European Commission specifies an increase in the export tax on Norwegian salmon entering EU markets from 0.75% to 3.00% effective 1 July 1997. Further, Norway’s exports are subject to a price floor and quantity ceiling, neither of which were binding over the evaluation period. Since the tax’s proceeds are to be used by Norway to fund generic marketing of Atlantic salmon, it is possible that the agreement is winwin, i.e., benefits United Kingdom and Norwegian producers alike. To test this, we use an equilibrium displacement model to estimate the agreement’s effects on prices, trade flows, and producer welfare. Results based on data through 1999 suggest the agreement is indeed win-win, but that currency realignments and feed quota policy can easily neutralize or obscure the effects.

Retail pricing strategies incorporate promotions, sales, and rigidities. A number of models have been proposed in particular to explain the occurrence of sales. Focussing on the market for fresh foods the model by Varian and the loss leader argument seem to be intuitively best fitting to the conditions in the fresh food market.

From these models we derive several hypotheses that are tested for a unique data set of the German fresh food retail market. The data set consists of weekly prices for ten food items in 131 grocery shops over the period from 1995 to 2000. Following Varian sales should lead to reduced expenditures, while the loss leader argument assumes that consumers are lured into the shop by promotional sales which are covered by higher prices for other products. The results indicate that expenditures decrease with the number of sales in the short run but this effect is outweighed by a dynamic price adjustment thereafter.

Various forms of revenue insurance have been applied in Canada and in the US with relative success. In this paper different combinations of traditional agricultural policies and revenue and yield insurance are analysed for the Spanish olive oil sector. Taking a database containing about half million Spanish olive growers during 8 campaigns, five possible policies are studied and the results are examined according to different criteria including average revenue and its variability, growers utility gains, taxpayers cost and the transfer efficiency of support. The policies analysed are:
(1) non-intervention;
(2) the policy currently in force in Spain that combines a production aid with a yield insurance;
(3) a revenue insurance, only;
(4) revenue insurance combined with a production aid; and
(5) an aid per tree in combination with revenue insurance.

The methodology is based on Monte-Carlo simulations performed on about 100 groups of growers that have been grouped according to their expected yields and variability. Assuming and estimating olive oil price and yields correlations for each group of growers, the analysis allows for consistent policy comparisons at a very disaggregate level. Using the results for all analysed groups, policies are ranked based on the above criteria at the provincial and national levels. Results show that the current regime of EU production aids of olive oil eliminates the advantage of extending the current yield insurance to a revenue insurance. It is also shown that the level of support delivered by production aids cannot be reached with revenue insurance even with completely subsidised premiums. Finally, it is shown that the policy that combines tree aids with revenue insurance exhibits good results for all examining criteria.

The replacement of wage-labour farms by family farms in Central and Eastern Europe during the transformation has been more limited than was initially expected. In this paper a formal framework is developed in order to analyse the behaviour of family farms and socialist-style farms in the presence of risk, given the typical post-socialist environment. Management incentives, ownership structure, lump-sum transfers and consumption choices are shown to have the potential to limit the size of family farms relative to socialist-style farms. The hypotheses are tested with survey data collected by the author in the Czech Republic.
