Why Do Dictators Have More Children?

At Foreign Policy's blog Passport, Joshua Keating notes an academic paper that found that the dictatorial a leader is, in general, the more children he has. From the paper:

We provide a theory whereby non-benevolent, non-democratic leaders increase their expected family size to raise the likelihood that a child will be a match at continuing the regime’s survival. As a consequence, having a larger family size raises the non-democratic leader’s expected rents that they can exploit from the citizenry. In contrast, democratic leaders have a lower desire to appropriate rents from the citizenry, and therefore have a diminished desire to have additional children for these purposes. We construct a data set of the number of children of country leaders as of August 31, 2005. We find that in a sample of 221 country leaders, fully non-democratic leaders have approximately 1.5–2.5 more actual children as compared to if they are fully democratic.
