The first order effect of a productivity increment in the output sector of a monocentric city which increase wages in the city is exactly capitalized in the increment in land rent in the city. We observe this result in the "open city" model in which a worker's utility level in city i is...

A consumer must decide not only to allocate his income among alternative items but also where to reside.The two decisions are ofcourse linked. On the income side, prices of goods often depend on shipping or transport costs and also one's net disposable income depends on one's out-of-pocket...

In this paper, the author shall demonstrate that when all demands and supply schedules are either linear or are points or scalars, then the generalized transportation problem and its dual can be expressed as a primal-dual quadratic program, this latter program being due to Dorn (1960) and...

In 1952, Samuelson (1952) showed how the problem of determining the flows of a commodity moving between spatially separated points in an equilibrium when transportation costs were positive could be treated as an extremum problem. Samuelson's approach was to maximize gross economic rent net of...

We report on the nature of a utility optimizing transfer from one regional government to another when local public goods are present. Computer examples reveal that small differences in regional endowments result in large differences in equilibrium outcomes for two regions, under optimal...

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...
