The Moses-Predöhl pull and the neoclassical location theory : An alternative approach

This paper shows that the appearance of the controversial Moses-Prednhl pull is due to the two-stage approach (the separation of the production decision and the location decision) which has been applied in the neoclassical location theory. It also shows the Moses-Prednhl pull is zero by using the well-known envelope theorem in the two-stage approach. Furthermore, it provides an alternative approach to show the Moses-Prednhl pull is zero by considering the production decison and the location decision simultaneously.

Transport rates structure,optimum location,and theory of production: Reexamination

The two-stage approach consistently to present a generalized location theory of the firm in linear space is employed. It is shown that the second-order sufficient condition for the profit-maximizing and/or cost-minimizing location problem requires that transport rates increase with distance. In the process, it is demonstrated that this approach provides a compact way to analyze the location and production decisions separately and to avoid the errors made by Mathur and others.

A probability model of the housing market based on quasi-classical considerations

This paper sets out a simple probability model for explaining locational patterns and trip-making in urban housing markets. As a prerequisite to formulating the model, the classical theory of residential location based on consumer theory is briefly outlined, and the difficulties of using such theory in an operational context are discussed. A more flexible approach, based on certain classical considerations involving rents, travel costs, and incomes is introduced and a model of the housing market is formulated using a probability-maximizing method. The model is then applied to residential location in the Reading sub-region, and tests of the model reveal that its performance in statistical terms is reasonable. In conclusion, certain possibilities for embedding the model into a more comprehensive modelling framework are explored.     

Two-stage optimal control problems and optimality conditions

When an optimal investment decision is studied for a firm whose capital goods are subject to a delivery lag, a control problem with a time-delay argument in the objective function emerges. Such a problem under a set of simple assumptions is shown to be reducible to a two-stage optimal control problem. The significance of this is that familiar tools from standard optimal control theory are applicable to the resulting two-stage problem. Necessary conditions are presented for a general two-stage problem with an adjustable switching time. Some specific results are also obtained for several special cases.     

Why and how do firms reshore? A contingency-based conceptual framework

Much of the growing body of reshoring literature has focused on why firms reverse a prior location decision. While valuable, this work needs extending to how the decision to reshore is operationalised. Using a two-stage approach, this paper presents a conceptual framework that covers both why and how firms reshore. The framework also utilises contingency theory to identify the factors that influence these decisions. It is therefore claimed to be more comprehensive than others frameworks found in the literature. First, a systematic literature review deductively develops an initial framework. Second, a revised version of the framework is presented using evidence from a single, exemplar case of captive reshoring in the textiles industry. The case evidence identifies new factors and extends a typology of reshoring decisions proposed in the literature to more accurately reflect the dynamic, complex, and incremental nature of the onshore-offshore-reshore location and ownership decision.
