<p>I am a very Macro guy, but I need to dive a little in the world of Microeconomics. Specifically, I need to study oligopolies. From the general theory to empirics. Since I do not know the literature, I would like to ask if anybody knows a good starting point. Preferably a paper that explains the strategic interactions between firms operating in a oligopoly.</p>
