The Lowry Model Revisited: Incorporating a Multizonal Input-Output Model into an Urban Land Use Allocation Model 总被引:2,自引:0,他引:2
Myung-jin Jun & James E. Moore 《Review of urban and regional development studies : RURDS : journal of the Applied Regional Conference》2002,14(1):2-17
This paper formulates a new generation of Lowry-style models that combine a multizonal input-output model and an urban land use allocation model. Three different types of models are proposed: 1) an unconstrained model, 2) a primal of a linear programming approach that includes land supply constraints, and 3) a modified dual of the linear programming approach that allocates land based on additional conditions of economic efficiency. The modified dual formulation improves upon the limitations of Lowry models and their derivatives. First, the proposed model has sound theoretical underpinnings that incorporate the production theory of input-output models and the behavioral theory of optimization models. Second, the proposed model allocates land on the basis of economic efficiency by imposing a procedure that equalizes shadow prices. And third, the proposed model is an optimization model that fully accounts for the spatial and sectoral relationships of multiplier effects determining land use demand. 相似文献

Currently, entrepreneurs and corporations overwhelmingly do not view the alleviation of global poverty as a strategic priority.
Yet business activity can have a negative as well as a positive effect on each distinctive form of poverty. In order to reduce
poverty, entrepreneurs have to find ways of limiting the negative aspects. This might be achieved by deliberately augmenting
strategies so that they can achieve a synthesis, in partnership with governments and NGO’s.

aspects of strategy and decision making and has served on the editorial boards of Journal of Business Ethics (to 2003), Human
Systems Management, Journal of International Entrepreneurship, African Journal of Business Ethics and the Journal of Economic

The English (Association) Football League is a long established industrial cartel selling a highly popular product with only imperfect substitutes. Despite that, the majority of its member clubs lose money and the industry has faced successive financial crises over the last decade. This paper develops an empirical model of the financial performance of English League clubs using a high quality dataset of 48 clubs over the period 1974–89. The underlying model explains how rents are competed away through the maximising behaviour of club owners subject to production constraints. This model is parameterised by a system of equations which describe the behaviour of a maximising owner subject to demand and production constraints. The model is then used to examine the coordination failure which lies at the heart of the English Football League's decline and to assess the prospects for the Premier League. 相似文献

This research develops models that extend existing multi-day analyses of shopping activity patterns. The main hypothesis is that shopping activity choice behavior varies, depending on the day of the week. Using a nested logit model structure, this hypothesis is tested by developing models of daily activity choice behavior for each day of the week. In doing so, household activity choice behavior is represented by three stages, with a shopping activity participation decision as the highest stage, the scheduling decision as the next lower stage, and the number of shopping stops as the lowest stage. Empirical results confirm the nested logit model structure hypothesized in this study. Furthermore, it is found that major distinctions in the daily utility functions take place between the weekday and weekend models. However, differences among weekday models are also observed. This indicates that there appear to be behavioral differences even among weekdays although households are exposed to the same set of temporal constraints. 相似文献

When assessing farming strategies, it is important to account for the opportunities provided for tactically adjusting to outcomes of risk. The hypothesis that accounting for tactical adjustment is more important than accounting for risk attitude was supported in this study with regard to identifying the optimal drainage recirculation strategy for an irrigated dairy farm. Failing to account for tactical adjustment would lead to a sub-optimal choice, costing the farmer about A$3 100 in present value terms. In contrast, failing to account for risk aversion would not affect the strategy chosen. The distribution method was found to be well suited to modelling tactical adjustment. 相似文献

This article reviews recent trends in the historiography of British industrial relations, and highlights a growing emphasis on the influence of employers and impersonal economic forces. In response, the article argues for a renewed recognition of trade unions as a proactive force in the development of industrial relations systems. This view is supported by analysis of the influence of market and institutional forces upon the spread of national collective bargaining. The conclusion is that commercial pressures on employers were relatively unimportant in a process driven by human agency, institutional forces, and wider economic pressures. 相似文献

The role of debt and equity changes over time and with the levelof development. What are these changes, and why should theysystematically occur across different countries and time periods?This article characterizes financial innovation as a dynamicprocess that both influences and is influenced by the developmentof the real sector. It focuses on the emergence and developmentof equity markets, using a model that allows for growth andfor capital accumulation that is financed externally througha combination of debt and equity. As an economy develops, theaggregate ratio of debt to equity will generally fall; yet,debt and equity remain complementary sources for the financingof capital investments. The results suggest how various governmentpolicy actions might affect capital accumulation and equitymarket activity. 相似文献
