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. Alan E. Singer is a reader in strategy at the university of Canterbury. He was the 2004/5 Aram chair of Business Ethics at Gonzaga. He is author of Strategy as Rationality (Avebury), Co editor (with Pat Werhane) of Business Ethics in Theory and Practice (Kluwer) and editor of Business Ethics and Strategy (Ashgate, forthcoming). He has written journal articles on many 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 Development and Business Policy.  相似文献

Modeling the day-of-the-week shopping activity and travel patterns   总被引:1,自引:0,他引:1

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

Hall and Miles (1990) suggest an approach of estimating default probabilities of banks using stock market information, and in this paper we apply an aggregated version of their approach to banking sectors around the world in both developed and emerging economies. We study the market’s assessment of the probability of systemic banking crises world wide over the last decade, including the Asian crisis 1997–1998. In addition, we investigate whether there is a relationship between the failure probability and institutional features of the actual banking sector. The quality of governance and the degree of law and order in a country is found to be significantly negatively related to the market based failure probabilities as is an explicit deposit insurance during periods of crisis.  相似文献

The aim of this paper is to trace and explain variations in calculative and collaborative human resource management (HRM) practices between companies and across national borders. Variations and similarities are explained in terms of the convergence and divergence of HRM practices determined by national institutions, and the increasing influence of multinational companies (MNCs). We explore the diffusion of HRM practices in Europe over time, using data sets from two surveys conducted in several European countries in 1995 and 2000. We use institutional explanations for the development of three selected bundles of HRM practices: individual, calculative performance‐oriented practices; collective incentive schemes for the alignment of interests; and collaborative practices that seek to enhance the commitment of employees. We found substantial effects of country‐specific institutions and of the country of origin of MNCs, which clearly support the institutional duality thesis. Foreign‐owned MNCs, especially those that are US‐based, appear to moderate country‐specific institutional effects on the diffusion of the three HRM bundles.  相似文献

Cash settlement of derivative contracts makes them susceptible to manipulation by traders who expect to close large positions upon final settlement. Cash settlement also increases underlying volatility when hedgers unwind their hedges if they have no incentives to control their trading costs. Limits on the positions that traders can carry into final settlement can be used to mitigate associated economic inefficiencies when surveillance is insufficient. This article develops a model that regulators can use to set these limits that is based upon microstructure theory. The empirical findings indicate that existing position limits are largely inconsistent with those suggested by the model. © 2005 Wiley Periodicals, Inc. Jrl Fut Mark 25:945–965, 2005  相似文献
