DIY International Arbitrage

by

The authors of a forthcoming Economics Letters article (pdf) gathered data from Amazon’s American, British, and Canadian web sites to demonstrate international price discrimination. According to the authors, Americans pay significantly more for textbooks on average. They offer a number of demand-side hypotheses but do not test them.

I’ve found a number of cases where American customers can save money by purchasing their textbooks from amazon.co.uk and paying for international shipping (£6.98) rather than using amazon.com. Check it out:

    Watch out for the duty. I had to pay more duty on a book I had sent from Amazon.co.uk to Canada than the original price of the volume. (It was not yet released in North America)

    Amazon’s US textbook ripoff?

    Are US students being ripped off by Amazon.com? Jonathan Dingel at Trade Diversion blog points to a forthcoming paper by Yale’s Christos Cabolis and colleagues, A Textbook Example of International Price Discrimination (PDF). The paper finds that althou…
