The Impacts of Environmental Policy on Industrial Allocation: A Transboundary Pollution Dynamic Game
研究了两个贸易地区在跨界污染下，环境政策如何影响企业分布和政府发放排污许可证的策略，发现污染损害较低时工业集中地区会放松环境监管以吸引更多企业。
Abstract We examine the impact of environmental policy on industrial location between two trading regions dealing with transboundary pollution. Firstly, we study how the distribution of firms and trade costs affect the governments’ environmental policies, particularly, the issuance of emission permits. Secondly, we study how the resulting environmental policies alter the allocation of the industry. The microeconomic behavior of the agents is framed within the Economic Geography literature, through a linear Footloose Capital (FC) model. The macroeconomic model that arises is a transboundary pollution dynamic game. When regions have different industrial shares, we find that if pollution damage is low, the more industrialized region adopts environmentally irresponsible behavior by increasing the offer of emission permits, which reduces their price. Firms benefit from lower production costs, ultimately attracting more firms (agglomeration force). However, due to transport costs, as the share of firms in a region increases, the benefits decrease (dispersion force). The final spatial distribution of the industry between the regions depends on the balance between agglomeration and dispersion forces. This agglomerative force and the governments’ strategic behavior, absent in the FC model, could lead to industrial activity fully concentrating in a core region. As pollution damage increases, agglomerative power loses strength.
