1 Introduction
Research Questions:
Is Free Trade Good or Bad for the Environment?
Which factors are affected by trade?
Direct or indirect impacts?
Methodology:
Structural Decomposition Analysis (SDA)
Panel Econometrics
Approach based on the seminal contribution by Antweiler, Copeland and Taylor (2001, A.E.R.)
Structural Change and the Environment

2 Data and Econometric Model
Used data from WIOD:
Information about Gross Output, Share of high-skilled workers
Environmental Satellite Accounts
Trade Data
Other data sources:
Income, Population, Investments (PWT 6.3)
Depreciation, TFP growth, Capital Stocks (EPWT 3.0)
Geographical informations such as distance, area etc. (CIA)
Data on patents (several sources)

3 Endogenity Problems
Problems:
Trade (TO) is endogenous
Income (INC) is endogenous too
Regulation (Helsinki)?
Reasons for Endogenity (among others):
Measurement Errors
Omitted Variables Problem
Simultaneity TO, INC, HELSINKI

Instrument Trade Openess (1/2):
Taken from the trade literature, Gravity-Model(see Frankel und Romer (1999, A.E.R.))
e.g. bilateral distance, common border, etc.: - strong correlation with actual trade openess - not correlated with SO2-Emissions or the error term

Instrument for Per Capita Income (1/2):
Taken from the growth literature:(see Mankiw, Romer und Weil (1992, Q.J.E.) and Frankel and Rose (2005, R.E.S.))
Conditional Convergence Hypothesis: - Lagged income - Investments and Depreciation - Population growth, Growth of labor productivity - additionaly from WIOD: share of high-skilled workers (HK)

Conclusions and drawbacks:
Currently it is hard to conclude whether free trade is good or bad for the environment. But: postive trade induced composition effects (in this case positive is bad)
Final report will include as many as possible WIOD data with respect to the environmental satellites, the trade data, output data, labor files and especially country coverage
Problem: Physical capital stock data is hardly available for the time and country period covered by WIOD. One possible solution: Perpetual Inventory Mehtod (Caselli (2005)).
Problem: Endogenity of Regulation
