This study examines the impact of the opportunity cost of urban land on urban growth. Based on prices, costs and productivity data on agricultural commodities at county levels, the opportunity cost of land was measured by the weighted revenue, cost, and government payment per acre of farm lands. Aggregating county data to metropolitan area levels, a panel data for 269 metropolitan areas from 1978-2000 were constructed. This study found that, as predicted by the theory, cities grow slower when revenue increases or cost decrease in the area. The impact of commodity program payment was also examined. Our results show that price shocks and agricultural subsidies do have an instantaneous impact on urban growth by a ecting the opportunity cost of urban land.

Why did EC enlargement negotiations with Spain take so long? This thesis argues that agricultural issues dominated negotiations despite the political and strategic aims of stabilizing Western Europe's southern flank that underpinned the raison d'être of this enlargement. The framework of Historical New Institutionalism is used to argue that several 'biases' operating at three levels account for the length and nature of these negotiations. At the first level, the 'bilateral' format of the negotiation procedure between Spain and the EC favoured existing EC members and protected the acquis communautaire. The Community's negotiating positions, as bargains in themselves, tended to be inflexible, and reduced Spain's input in the discussions and in the agenda-setting process. At the EC level, the CAP exhibited an unusual capacity to withstand the changes required by enlargement. This was because the EC's decisionmaking structure was fragmented into sectors and levels which allowed a closely knit 'policy community' to run the CAP in a way that was relatively insulated from other issue-areas. Change in the CAP occurred to cope with enlargement, but in a path-dependent way, passing the cost of adaptation on to Spain. At the national level, member states' so-called national interests with regard to enlargement were mixed, with no clear priority, and conflicting sectoral views. This resulted from the mechanisms of interest intermediation and inter-departmental co-ordination, which shaped the formulation and representation of national views in Brussels. Spain's accession was finally made possible when new redistributive policies for the Mediterranean and fresh budgetary resources were agreed. These were approved as part the wider package-deals surrounding the Single Market project and the Single European Act. HNI provides a new and persuasive framework with which to understand the difficulties of institutional change associated with enlargement negotiations.

This thesis is a study of the family farm, the authority of government as it relates to agriculture, the background of agriculture price support programs, agriculture price supports, the effects of agriculture price support, subsidy payments by the United States government, and the present trends.

O objetivo deste trabalho foi analisar o armazenamento do arroz no Brasil, propondo modelos para tomada de decisão quanto à formação de estoques. Uma vez conhecidos estes modelos é possível analisar previamente as intervenções pretendidas pelo governo. Para tanto se partiu da hipótese de que é possível representar o mercado de arroz no Brasil através de um modelo dinâmico de expectativas racionais capaz de captar o efeito da importação do produto e de algumas políticas de sustentação de preço ao produtor adotadas pelo governo brasileiro. A proposta metodológica para a estimação do modelo segue a abordagem de programação dinâmica. Foram desenvolvidos algoritmos que representam o mercado de arroz no Brasil em uma situação de mercado fechado sem intervenção do governo, mercado aberto sem intervenção do governo, mercado fechado com intervenção do governo via Prêmio de Escoamento do Produto - PEP, mercado fechado com intervenção do governo via Aquisição do Governo Federal - AGF mercado aberto com intervenção do governo via PEP, mercado aberto com intervenção do governo via AGF. Os métodos utilizados para solução exigem que sejam conhecidos as funções de demanda e oferta de área, o custo unitário de armazenamento, a taxa anual de juros, a distribuição de probabilidades das variáveis aleatórias (produtividade e choques de demanda) e os preços de importação e mínimos (quando for o caso). Os preços esperados de mercado na situação de mercado aberto com intervenção via PEP foram ligeiramente inferiores ao preço de mercado sem intervenção, porém o preço recebido pelo agricultor foi ligeiramente maior. Isto significa que parte dos recursos da PEP é apropriada pelo produtor e parte pela indústria. Os resultados do modelo aberto com AGF demonstram que os preços para o comprador ficam acima do encontrado para o modelo sem intervenção do governo. Outro resultado encontrado foi que o nível de preços mínimos praticado nos últimos anos não tem sido suficientemente elevado a ponto de promover mudanças significativas no equilíbrio de mercado interno. / The aim of this study was to analyze rice storage in Brazil, proposing a model for decision taking regarding stock formation. Once these models are known it is possible to previously analyze the government interventions. Thus, the study was based on the hypothesis that it is possible to represent the rice market in Brazil through a dynamic model of rational expectations able to analyze the product importation effect and some policies of price support to the producer adopted by the Brazilian government. The methodological proposal for estimating the model follows the dynamic programming approach. It was developed algorithms which represent the rice market in Brazil in a situation of closed market without the government intervention, open market without government intervention, closed market with the government intervention through PEP (Prêmio de Escoamento do Produto - Prize for Product Outletting), closed market with the government intervention through AGF (Aquisição do Governo Federal - Federal Government Acquisition), open market with the government intervention through PEP, open market with government intervention through AGF. The methods used for the solution require that it be known the demand and supply functions for the area, the unit storage cost, the annual interest rate, the distribution of probabilities of random variables (productivity and demand shocks), importation and minimum (whenever is the case) prices. The expected market prices in the situation of open market with intervention through PEP were slightly lower than to the market price without intervention, however the price received by the grower was a little higher. It means that part of the PEP resources is allotted by the grower and part by the industry. The results of the open model with AGF show that the prices for the buyer are higher than those found in the model without government intervention. Another result was that the level of minimum prices practiced over the last years has not been adjusted to the point to promote significant changes in the balance of the domestic market.
