This paper studies the eff ects of foreign competition on self-employment levels. We begin by pointing out a previously unknown fact: the greater the exposure to foreign competition, the smaller the fraction of self-employed people. This fact holds across very different countries, across...

We introduce a dynamic network model with probabilistic link functions that depend on stochastically time-varying parameters. We adopt the widely used blockmodel framework and allow the highdimensional vector of link probabilities to be a function of a low-dimensional set of dynamic factors. The...
