The best popular magazine that deals with IPE issues is The Economist, which can be found on the web at http://www.economist.com
In every issue they have a one page summary of recent developments in economics. Their periodic "surveys," which cover topics such as globalization or the Asian currency crisis, are invaluable introductions.
The best single newspaper for following events in IPE is The Financial Times, which can be found on the web at
http://news.ft.com/world
The FT is a particularly good place to keep track of what is happening at G-7 summits, debates within the IMF, etc. They too produce periodic "Surveys" but they tend to focus on the economies of particular countries or industries, eg., "energy" or "Turkish telecommunications."
The major academic journal for the study of IPE is still International Organization, although there are old (World Politics) and new (Review of International Political Economy) competitors. It is available in electronic form through the Jafet library's access to the JSTOR database.
There are also a number of top-flight economists who maintain webpages dealing with IPE. The most important are probably:
Nouriel Roubini's Asian Crisis Webpage:
