For a number of years the IMF has published a monthly magazine called Finance and Development (www.imf.org/faand ), available both on the web and in hard copy (free subscription). This magazine has evolved to become an unusually interesting (and underappreciated) forum for discussion of important issues. If you are interested in IPE you should check it out.
The current issue, for example, has several articles related to the issue's theme, which is the importance of empowering women in economic development. Other sections include several articles that look at the changes since the Asian financial crisis of 1997, examine investment problems in China and consider how to make remittances more effective in Africa. There is also a primer on microfinance and some thoughtful book reviews. The articles are fairly short, contain useful data, and are written for an informed audience (like our IPE students at Puget Sound) but try avoid technical jargon for the most part.
Recommended reading and an excellent place to look if you are having trouble coming up with a topic for your senior thesis.
