This paper investigates efficiency and equitability issues given a cost sharing method in an economy with a public commodity. We study the concept of a -cost share equilibrium and examine the set of all equilibrium allocations. Finally, we devise a mechanism to implement -cost share equilibria as strong equilibria of an associated non-cooperative game.This paper was written while Shlomo Weber was visiting the University of Bonn.

This paper examines the effects of introducing competition into monopolized network industries on prices and infrastructure
quality. Analyzing a model with reduced-form demand, we first show that deregulating an integrated monopoly cannot simultaneously
decrease the retail price and increase infrastructure quality. Second, we derive conditions under which reducing both retail
price and infrastructure quality relative to the integrated monopoly outcome increases welfare. Third, we argue that restructuring
and setting very low access charges may yield welfare losses, as infrastructure investment is undermined. We provide an extensive
analysis of the linear demand model and discuss policy implications. 相似文献

In order to assess the impact of patent infringement on the growth of a new product, a model is developed through the intervention model development processes of Box-Jenkins and Box-Tiao. Physical interpretations of model parameters and determination of associated damages suggest that the model can provide a sound basis for analyzing patent infringement disputes. 相似文献

Macroeconomic forecasting using structural factor analysis 总被引:1,自引:0,他引:1
The use of a small number of underlying factors to summarize the information from a much larger set of information variables is one of the new frontiers in forecasting. In prior work, the estimated factors have not usually had a structural interpretation and the factors have not been chosen on a theoretical basis. In this paper we propose several variants of a general structural factor forecasting model, and use these to forecast certain key macroeconomic variables. We make the choice of factors more structurally meaningful by estimating factors from subsets of information variables, where these variables can be assigned to subsets on the basis of economic theory. We compare the forecasting performance of the structural factor forecasting model with that of a univariate AR model, a standard VAR model, and some non-structural factor forecasting models. The results suggest that our structural factor forecasting model performs significantly better in forecasting real activity variables, especially at short horizons. 相似文献

The Risk Structure of Land Markets 总被引:3,自引:0,他引:3
Real property as an asset class represents over half of the wealth in the United States. Nevertheless, the structure of risk in real property markets is poorly understood. This paper develops a model of urban and agricultural land prices that integrates spatial and asset pricing theories and characterizes the spatial and temporal risk structure of the land market. Urban land is priced by a CAPM and agricultural land is priced by a real option to convert into urban land. We show that the price of land awaiting conversion increases with the growth rate of urban rents and unsystematic risk but decreases with risk aversion. However, it may be increasing or decreasing in systematic risk. The free boundary for exercise determines city size, which increases with the growth rate of urban rents but decreases with systematic and unsystematic risk. 相似文献

This article explicitly incorporates layoff and hiring costs into a discretetime dynamic model with stationary demand uncertainty, in which managers in a cooperative learn something about the demand process over time, and anticipate learning something about that process. It is shown how the opportunity to learn affects initial membership size and how the knowledge gained induces changes in membership, as well as how risk preferences impact on membership size at any point in time. 相似文献
