Over the last three decades we have observed a dramatic increase in the concentration of income at the very top of the distribution. This increase in income inequality has been especially steep in the managerial occupations in financial industries, where it has often been associated with greater...

We study a general equilibrium model in which entrepreneurs finance investment with optimal financial contracts. Because of enforceability problems, contracts are constrained efficient. We show that limited enforceability amplifies the impact of technological innovations on aggregate output....

We study how barriers to competition---such as restrictions to business start-up and strict enforcement of covenants or IPR---affect the investment in knowledge capital when contracts are not enforceable. These barriers lower the competition for human capital and reduce the incentive to...

In this paper we develop a general equilibrium model in which firms finance investment by signing long-term contracts with a financial intermediary. Due to enforceability problems, financial contracts are constrained optimal, that is, they maximize the surplus of the contract subject to...

We study how barriers to business start-up affect the investment in knowledge capital when contracts are not enforceable. Barriers to business start-up lower the competition for knowledge capital and, in absence of commitment, reduce the incentive to accumulate knowledge. As a result, countries...
