“…In several regions, their algorithm is being extensively used to find spatial equilibrium conditions and to determine the commercial exchange of goods between interrelated regions. Recently, given the advance in computer capacities and new computing strategies, the size of the models has been amplified (Takayama, 1995).…”

In the production chain of soybeans in Brazil a sizable part of the corresponding cost structure is the result of logistics costs. Given the location of its production sites, distant from the ocean, the optimization of the transportation costs is essential for preserving competitiveness. Using nonlinear programming, this study proposes a spatial multimodal and temporal equilibrium model. The applicability of the model is tested with a case study regarding the exports of the soybeans produced in three states in the northern part of the Brazilian cerrado region. In the state of Tocantins, the effects of infrastructure investments in the competitiveness of the production are described through four proposed scenarios, while the basic scenario compares the three states. The data are treated using the GAMS/MINOS program. The study asserts that soybean production will be more competitive if warehousing facilities are used extensively and when the project hydroway becomes operational.Keywords: logistics; soybeans; warehousing; nonlinear programming. ResumoNa cadeia de produção da soja no Brasil, parte substancial da estrutura correspondente dos custos é resultado dos custos logísticos. Dada a localização das áreas produtivas, distante do oceano, a otimização dos custos de transporte é essencial para garantir a competitividade. Usando programação não-linear, este estudo propõe um modelo de equilíbrio espacial temporal e multimodal. A aplicabilidade do modelo proposto é testada com um estudo de caso referente às exportações de soja produzida em três estados na parte norte do cerrado brasileiro. No estado de Tocantins, o efeito na competitividade de investimentos na infraestrutura de transporte estão descritos por meio de quatro cenários, enquanto que os três estados são comparados pelo cenário básico. Os dados são tratados usando o programa GAMS/MINOS. O estudo assegura que a produção de soja nesses estados será mais competitiva se armazéns forem usados mais extensamente e quando o projeto hidroviário tornar-se operacional.Palavras-chave: logística; soja; armazenamento; programação não-linear.

“…A second observation is that rural economic analysis seems to have become the recipient of the intellectual hand-me-downs; as new theory and models are received within the urban economic sphere, those that are displaced often find new life in rural applications. This is gross generalization and ignores the fact, for example, that the motivation for spatial price equilibrium models emanated from Iowa and focused on agricultural commodity flows (for an enlightening exposition, see Takayama 1996). In support, note the use of economic base, input-output, and social accounting models, shift and share analysis, and the stream of analysis that may be collected under the rubric growth-center/cluster analysis.…”

New Goals for New Rural Policies

The basic question is whether rural America is sustainable in its present form. America’s hegemonic position in world agricultural commodity trade is eroding. The lessons from urban America suggest that structural transformation is both painful and necessary. Improving rural infrastructure will be an important objective, but the benefits may be smaller than similar investments in metropolitan areas. Expanding agricultural opportunities will be important, through value-added processing and new specialized crops. Lifting rural human capital will be an essential ingredient in spurring new rural business formation. Finally, improving rural economic networks will be an important step in harnessing the potential of small businesses that typify the rural economic landscape. There will not be one way to address the myriad problems in rural America, but any new rural policies must recognize that not all rural communities may be viable in the future.

This paper addresses the impact of transport infrastructure projects of manufacturing employment in Thai regions. After a theoretical review we consider the impact of various transport modes: road, rail and ports. We find that roads and ports have a positive impact on industrial location, although the size of the impact is modest. Labor appears to be a more important location factor in Thailand. For the analysis of the data, geographical information systems (GE) appear to be a quite useful tool.
