Spatial Dimensions of Environmental Policies for Transboundary Externalities: A Spatial Price Equilibrium Approach

Spatial Price Equilibrium

Spatial Externalities, Spatial Multipliers and Spatial Econometrics

This paper outlines a taxonomy of spatial econometric model specifications that incorporate spatial externalities in various ways. The point of departure is a reduced form in which local or global spillovers are expressed as spatial multipliers. From this, a range of familiar and less familiar specifications is derived for the structural form of a spatial regression.

Transboundary Spillovers and Decentralization of Environmental Policies

Most US federal environmental policies allow states to assume responsibility for implementation and enforcement of regulations; states with this responsibility are referred to as “authorized” or having “primacy.” Although such decentralization may have benefits, it may also have costs with pollution spillovers across states. This paper estimates these costs empirically by studying the free ridi...

Formulation and Analysis of a Dynamic Spatial Price Equilibrium Model

The spatial price equilibrium model begins with the Hitchcock-Koopmans transportation problem as described by Dantzig (1963). The data for this model includes a set of suppliers I and a set of markets J , with supplies ai, demands bj, transport costs cij from supplier i to market j. Cast as a planning problem, this linear program seeks a transport schedule which minimizes the cost of supplying ...

Sensitivity analysis for time dependent spatial price equilibrium problem

We present some sensitivity results for the spatial price equilibrium problem in the case of quantity formulation model and in presence of excess supply and excess demand. The equilibrium conditions that describe the above model are expressed in terms of a time dependent variational inequality. The variational inequality formulation plays a fundamental role in order to achieve the sensitivity r...
