The Hitchcock-Koopmans transportation problem is linked to the gravity model of regional analysis with the aid of two new analytical results. Eighty transportation problems are generated by Monte Carlo methods and solved by linear programming. The transportation cost minimizing flows are...

Interregional input-output models have seldom been empirically articulated owing no doubt to the inordinate demands made on research teams to collect data on economic flows and to prepare the oeffecients required int he models. This paper talks about a more recent model, which is that of...

We demonstrate the following result: if along dynamically efficient development paths, the net current value of the diminution in natural resources stocks, renewable and non-renewable, is invested in reproducible capital, per capita consumption will remain constant over time in a world of...

The Hitchcock-Koopmans (HK) transportation problem in linear programming (4), (5) and the Cournot-Enke-Samuelson (KES) pricing problem in spatial price equilibrium (2), (3), (6) are two classic analyses in the theory of transportation costs. In this paper, I generalize the HK analysis to take...

At each date, the two players play an R & D investment game "followed" by a Cournot quantity setting game. Each player's R & D augments the common stock of technical knowledge and lowers goods production costs for each player. Profit gross of R & D investment expenditures are quadratic in the...

We characterize the multiplicity of patterns of trade in the neo-classical two country, two factor, two final good model extended to incorporate an essential intermediate good. With factor price equalization and no trade in the intermediate good, there are no gains from trade by opening up the...

We formulate the Malthus-Hardin tragedy of the commons as a special case of dynamic game between "tribes". At each date a member of a tribe desires more newborns of her/his type and more current consumption, harvested from the commons. Equilibrium in the dynamic game yields steady state level of...

The idea that a final product (the pin) is made of a certain number of components combined in fixed proportions and that a worker can have a comparative advantage in producing one component relative to his fellow workers is developed. We investigate efficient allocations of worker to tasks and...

In a two good, two factor small open economy with neoclassical production functions, we investigate conditions for Giffenness of imports with respect to the price of the imported good. Of interest is the shape of the consumption-trade frontier (the locus of points chosen as world prices vary)...

The theory of the location of the firm is characterized by a number of classic analyses. Each analysis has been concerned with developing a particular property of equilibrium location of the firm, in general, for quite different models of markets. However, there is a consistent conceptual...
