In a model of strategic network formation, the endogenously formed network is built around a pre-existing network. We envisage that the pre-existing or core network is publicly provided. Strategic network formation is decentralized: Players act in their private interest and bear the costs when...

We consider competitive markets for multiple commodities with endogenous formation of one- or two-person households. Within each two-person household, externalities from the partner’s commodity consumption and unpriced actions are allowed. Each individual has two types of traits:...

We present a variant of a general equilibrium model with group formation to study how changes of non-consumptive beneï¬ts from group formation impact on the well-being of group members. We identify a human relations paradox: Positive externalities increase, but none of the group members gains...

First a non-cooperative model of network formation is investigated where link formation is one-sided and information flow is two-way. For that model, the relationship between different notions of efficient networks is studied: Pareto optimal networks on the one hand and welfare maximizing...

The present paper examines zero-sum games that are based on a cyclic preference relation defined over anonymous actions. For each of these games, the set of Nash equilibria is characterized. When the number of actions is odd, a unique Nash equilibrium is always obtained. On the other hand, in...

In this paper, the age-hardening behavior and phase transformation of Mg-9.2Gd-1.9Y-1.8Zn-0.5Zr alloy were systematically studied. The results showed that the aging strengthening effect of the alloy is significant at 225°C. In under-aging stage, the second phases are mainly nucleation,...

In this paper, a spatial simultaneous growth equilibrium model of employment growth, migration behavior, median household income and local public expenditures is developed. The model is empirically estimated by Generalized Spatial Three-Stage Least Squares estimator using count- level data from...

We describe a simple algorithm that permits the sequential (period-by-period) solution of large-scale dynamic CGE models with agents who have perfect foresight over an infinite number of periods. The algorithm requires neither any assumptions about behavior in a ?final? period nor that the base...

When urban renewal projects require that smaller parcels be assembled into a single large one, owners who hold out for higher prices may either prevent or significantly delay socially efficient redevelopment. Local governments seeking private redevelopment currently have only the choice between...
