In this paper we use a general equilibrium model to examine the effects of international quota transfer when a quota restricts world commodity production whilst the trade in an intermediate good is not regulated. The analysis shows that, when the quota regime is not internationally transferable, intermediate input trade substitutes for final good trade. In these circumstances, the distortions are lower than expected. International quota transfer increases world welfare proportionally to quota rent gap. Welfare distribution is also conditioned by commodity terms of trade and, particularly, by the outcome of the intermediate good price.

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.

Bade and Parkin have changed all that for the better. In the book they provide a serious yet accessible economics course that is focused on helping students:
understand the basic principles of economics
connect these principles to today's economic issues
develop a lasting interest in economics as a relevant part of their own lives.
Each chapter focuses on a limited number of core concepts, to allow students to thoroughly explore, analyze, and review a concept before moving on to the next one. Learning objectives are explicitly linked at the beginning of each chapter to the core concepts; checkpoints maintain and refer back to these specific links. Chapters are formatted with a carefully balanced blend of text and graphics that provide visual clarification without clutter or unnecessary distractions. The writing style throughout is fluid and conversational, reinforcing the underlying principle that economics is an everyday issue that can be addressed in everyday language.

As part of its food security policy, South Korea has been pursuing food self-sufficiency using high tariffs and high administrative prices in key agricultural and food markets. Using a dual approach to trade and trade restrictiveness indices, we analyze the impact of these market distortions on welfare and trade volume. Then, we compute optimum distortions, which minimize the welfare cost of observed self-sufficiency and production objectives. We rationalize these optimum distortions to what could be claimed as legitimate protection under a “food security” (FS) box in World Trade Organization negotiations. FS-box protection is sensitive to changes in the definition and the extent of the FS objectives. We show that FS via production targets and reliance on imports would be more palatable to consumers and trade partners, while preserving rents to the farm sector.

On farm conservation of crop diversity entails policy challenges, especially when the diversity of crops maintained on farms has both inter-specific (among crops) and infra-specific (within a crop) components. Survey data is used to compare the determinants of inter- and infra-specific diversity on household farms in the highlands of northern Ethiopia. Physical features of the farm, and household characteristics such as livestock assets and the proportion of adults that are men, have large and significant effects on both the diversity among and within cereal crops grown, varying among crops. Demographic aspects such as age of household head and adult education levels affect only infra-specific diversity of cereals. Though there are no apparent trade-offs between policies that would enhance one type of diversity (richness) versus another (evenness), those designed to encourage infra-specific diversity in one cereal crop might have the opposite effect on another crop. Trade-offs between development and diversity in this resource-poor system are not evident. Market-related variables and population density have ambiguous effects. Education positively influences cereal crop diversity. Growing modern varieties of maize or wheat does not detract from the richness or evenness of these cereals on household farms.

The European Union beef market regulation is largely influenced by the Common Agricultural Policy (CAP). With the 1992 CAP reform, there was a partial shift by the EU from product price support to a more direct form of income support by way of direct payments. For beef there was a move to direct payments on intermediate products which was essentially a direct payment for the possession of various categories of animals and these were linked to a land resource base. The Agenda 2000 reform consists in a further price decrease associated with an increase in direct payments. The objective of this paper is to assess how the behaviour of beef producers is sensitive to changes in production prices and to changes in premiums. The analysis relies on an analytical framework which allows to take into account the dynamic feature of beef production and the subsidies provided by the Common Agricultural Policy. We studys how the beef supply response is modified when various exogenous variables like prices or premiums are changed. The application focuses on the dynamics of beef supply response in the French beef sector.

The ongoing negotiations in the WTO will most certainly lead to a further liberalization of the global agricultural trade. Related to this, many national governments, including Norway, Switzerland and Japan have placed substantial emphasis on the so-called non-trade concerns. In addition to the production of food and fiber, agriculture also provides or may provide national food security, environmental benefits, and viable rural areas. The term “Multifunctional Agriculture” has been applied to describe these additional functions. In this paper, we will show how the economic concepts of “positive and negative externalities” and “public goods” can be used to analyse non-trade concerns and multifunctionality, especially with reference to agriculture’s impact on the environment. We conclude the paper with suggestions for international trade rules that can allow countries to meet domestic environmental policy objectives in a minimally trade-distorting manner.

The public R&D capital stock is introduced as a quasi-fixed input in a variable cost function. The relative shadow price allows the correct measurement of the equilibrium levels of quasi-fixed inputs thus explicitly assessing the hypothesis of public R&D under (over) investment. By introducing an appropriate R&D price in the long-run equilibrium, the model can also provide empirical evidence on the rationale driving public R&D investment and on the hypothesis that free-riding on public R&D can explain overinvestment. Moreover, the model allows a formal testing of the induced innovation hypothesis and a more accurate calculation of both internal rate of return to R&D and residual exogenous productivity growth. The empirical implications of the model are appraised in the case of Italian agriculture for the period 1960-1995.

Based on the Policy Analysis Matrix (PAM) approach this paper provides an assessment of the competitive position of the Hungarian agro-food industry in view of EU integration. The situation in the food processing sector is assessed with the use of actual cost data from representative Hungarian companies. The paper presents an assessment of the current situation prior to EU integration as well as a future outlook under various scenarios with regard to the expected policy environment and the rate of technological change. The actual measurement of competitiveness in this study focuses mainly on Private Resource Cost (PRC) which indicates competitiveness under real market conditions and Domestic Resource Cost (DRC) which gives an assessment on the social or economic efficiency of an activity, i.e. whether domestic resources are really used efficiently in current production. In the food processing sector 21 different food products have been investigated which fall into four industries: meat, poultry, dairy, and fruits and vegetables. Under current conditions only some products are competitive in private terms. The situation would improve after EU integration especially for poultry, fruits and vegetables, because agricultural policy conditions are more favourable under the CAP. If additional FDI(Foreign Direct Investments) would flow into the country after EU membership, this would boost profitability. As far as DRC values are concerned, it must be stated that only some of the production activities are clearly efficient. Dairy, fruits and vegetables, and roast goose production show relatively weak social competitiveness, while other poultry and fruit and vegetables products are more favourable from the economic point of view. As EU policies provide on average higher protection levels, the competitiveness of Hungarian food processing on world markets would deteriorate for most products after EU accession. However, these effects can be offset by additional technological change due to FDI inflows or otherwise induced technological progress.

Uncertainty about the possibility of acquiring land can be rather large in the EU for sectors like dairy farming. Farm-level investment decisions are commonly made ex-ante when the farmer is not certain about the possibility of purchasing land. This possibility is realized only in a future period. In this paper, we have developed and applied a simple two-period model in which a profit-maximizing farmer, facing uncertainty about the possibility of acquiring land, had to choose the optimal mix of capital (buildings) investment and land endowment. We have shown that commonly "observed" biases towards non-optimal investment decisions are not necessarily justified. Rather, these perceived biases may be the result of evaluating investment decisions without reference to the uncertainty associated with the possibility of acquiring land.

The paper analyzes the impact of different agricultural trade policies on Russia’s bilateral trade patterns, price and quantity changes, and welfare effects for producers, consumers, and the state budget. Three experiments are simulated using a partial equilibrium model based on the Armington approach. The results show that the current situation of import tariff-free trade between Russia and other CIS countries has small positive welfare effects for the Russian Federation in comparison to a situation where import tariffs between these countries were to be imposed.

However, according to the results, an elimination of import tariffs against all trading partners is preferable for Russia in terms of net welfare. An increase in discriminatory trade barriers against non-CIS countries would cause overall welfare losses for the Russian economy.

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.
