تنوع، ساختار هزینه و صرف ریسک شرکت های چند ملیتی

We investigate theoretically and empirically the relationship between the geographic structure of a multinational corporation and its risk premium. Our structural model suggests two channels. On the one hand, multinational activity offers diversification benefits: risk premia should be higher for firms operating in countries where shocks co-vary more with the domestic ones. Second, hysteresis and operating leverage induced by fixed and sunk costs of production imply that risk premia should be higher for firms operating in countries where it is costlier to enter and produce. Our empirical analysis confirms these predictions and delivers a decomposition of firm-level risk premia into individual countries' contributions.
