Two of the most important developments in the global economy of the recent decades are the integration of emerging markets into world capital markets and their rapid growth, particularly in certain parts of Asia. Alongside these events are three striking and unprecedented macroeconomic trends: (i) a large and persistent increase in the private saving rate in emerging Asia against a steady decline in the private saving rate in advanced economies; (ii) the emergence of global imbalances, with developing countries running a large current account surplus and advanced economies a current account deficit; (iii) a sustained fall in the world long-term interest rate.These global patterns challenge standard open-economy growth models. Fast-growing emerging economies should, according to neoclassical theory, borrow

We study the relation between firm growth and managerial incentive provision under moral hazard when a long-lived firm is operated by a sequence of managers. In our model, firms replace their managers not only upon poor performance to provide incentives, but also when outside managers are at a comparative advantage to lead the firm through a new growth phase. We show how the optimal contract can be implemented with a system of deferred compensation credit and bonuses, along with dismissal and severance policies. Firms with better investment prospects have higher managerial turnover and rely on more front-loaded compensation schemes. Growthinduced turnover can result in positive severance if the principal needs to incentivize the manager to truthfully report the arrival of a growth opportunity. Realized firm growth depends jointly on the exogenous arrival of growth opportunities and the severity of the moral hazard problem. We also find a new component of agency costs due to the spillover effect of the tenure of the incumbent manager onto the present value of future managers' compensation.
