Before revision:  Firms' growth rates are negatively correlated with size and follow a core double-exponential distribution followed by fat tails. Firms' size and production network are power-law distributed. These properties emerge because continuous inflow of new firms shifts away the model from a steady state to a disequilibrium regime in which firms get scaled according to their resistance to competitive forces .
After revision:  Our main result is that competition between intermediate good producers generically leads to the emergence of scale-free production networks .
