|Title:||Trade and the environment: The role of firm heterogeneity |
Richter, Philipp M.
|Issue Date:||2012 |
|Series/Report no.:||Discussion Papers, German Institute for Economic Research, DIW Berlin 1214|
|Abstract:||This paper derives a new effect of trade liberalisation on the quality of the environment. We show that in the presence of heterogeneous firms the aggregate volume of emissions is influenced not only by the long-established scale effect, but also by a reallocation effect resulting from an increase in the relative size of more productive firms. We show how the relative importance of these effects, and hence the overall effect of trade liberalisation on the environment, is affected by the emission-intensity at the firm level: Aggregate emissions decrease when trade is liberalised if and only if firm-specific emission intensity decreases strongly with increasing firm productivity.|
