Extortion as an obstacle to economic growth: A dynamic game analysis

In this paper we use a differential game analysis to study the dynamic strategic interaction between a criminal gang extorting money from local shop- owners and the police force. In particular, we are interested in characterizing which factors are important in determining whether the capital stock of local shop-owners keeps growing in spite of extortion or the criminal activity leads to a phase of stagnation of the local economy. A Markov perfect equilibrium of the game is characterized in order to address this question and several policy implications are derived to facilitate growth in regions affected by extortion.
