Abstract:
The relationship between trade liberalisation and the
environment has been the subject of a growing body of literature in recent
years. One particular focus of attention has been the issue of whether
environmental regulations are influencing patterns of international trade. This
paper aims to examine this issue in the context of the Heckscher-Ohlin-Vanek
(HOV) model of trade, but also in a 'new' trade model characterised by
monopolistic competition and differentiated products. Our use of the HOV model
improves upon a well cited study by Tobey (1990) in many ways, not least by
allowing for the possible endogeneity of environmental regulations. We find no
statistically significant relationship between such regulations and 'dirty' net
exports. The 'new' trade model explains the presence of both intra and
inter-industry trade and we again allow for the possible endogeneity of
environmental regulations. We believe this to be the first study to assess the
role of environmental regulations within a 'new' trade model, but also the
first to allow for the endogeneity of regulations in a cross-country model of
trade. In the context of this model, we find environmental regulations to be a
statistically significant determinant of the share of inter-industry trade (net
trade) and we find this significance to increase when endogeneity is controlled
for.
