Quantifying the value of a political connection : the case of presidential elections in Colombia

Using a novel biographical database including all Presidents and presidential candidates in Colombia for the period 1833-2010 I show that the value of a political connection can be quantified in terms of the votes transferred within a political network. I consider three types of political networks depending on whether links are created by a cabinet or foreign service appointment and a family connection. I find that a one standard deviation increase in votes received by connections generates a maximum gain of three-fourths of a standard deviation. I also reject for the presence of network endogeneity that may bias the estimates.
