The separation of ownership and control allows controlling shareholders to pursue private benefits. We develop an analytically tractable dynamic stochastic general equilibrium model to study asset pricing and welfare implications of imperfect investor protection. Consistent with empirical evidence, the model predicts that countries with weaker investor protection have more incentives to overinvest, lower Tobin's q, higher return volatility, larger risk premium, and higher interest rate. Calibrating the model to the Korean economy reveals that perfecting investor protection increases the stock market's value by 22 percent, a gain for which outside shareholders are willing to pay 11 percent of their capital stock.

The empirical evidence on trade reforms suggests that these have a surprisingly small impact on the country's industrial configuration. This industrial structure inertia is difficult to rationalize in standard trade models. This paper develops a two-sector industry dynamics model in which industrial composition inertia arises naturally. The model is then used to study the consequences of different types of trade reforms (e.g. permanent, temporary, gradual, pre-announced) on investment, employment composition, and income distribution.
