Papers on International Trade and Environment everyone. 

As a requirement to get my bachelor's in economics, I have to write a paper. The theme I picked is something along the lines of "the impact of environmental crimes and regulation on international trade". The problem is I've always worked on topics that are based on microeconomics, never on macroeconomics. 

Therefore, I'd like to ask for paper recommendations on international trade, if possible related to environmental issues, as a way for me to develop a solid foundation regarding this macroeconomic topic. 

I'll also be consulting Krugman's book, but I feel reading some papers that use theories and models tailored to international trade might be very useful. 

I appreciate any help!

Feel free to ask for any clarifications if needed.

Kind regards,
Pedro.
I have to disagree with the previous answer. There is quite a large literature on international trade and the effect of environmental regulations. To start off there is the whole race to the bottom literature and the environmental Kuznet's curve. A good start of trade versus the environment is given in Esty's 2001 Bridging the Trade-Environment Divide (found a.o. here). Copeland and Scott Taylor have a 2004 article on international trade, growth and the environment in the journal of economic literature.

As for trade in natural resources and related trade policies Ruta and Venables have an overview paper here. 

For a more general equilibrium model on differences in environmental regulations and how that affects trade you could start at Chichilnisky's 1993 North-South trade and the dynamics of renewable resources (here).
