If democracy is to have the good effects said to justify it, it must be self-enforcing in that incumbents choose to hold regular, competitive elections and comply with the results. I consider models of electoral accountability that allow rulers a choice of whether to hold elections and citizens...

The author distinguishes between two types of costly signals that state leaders might employ in trying to credibly communicate their foreign policy interests to other states, whether in the realm of grand strategy or crisis diplomacy.

We examine the theoretical implications of the observation that ethnic identities are socially constructed for explaining ethnic violence, distinguishing between two classes of mechanisms. If individuals are viewed as the agents who construct identities, then constructivist explanations for...
