Over the last three decades there has been a dramatic increase in the size of the financial sector and in the compensation of financial executives. This increase has been associated with greater risk-taking and the use of more complex financial instruments. Parallel to this trend, the...

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...

An algorithm is presented which provides a complete solution to the optimal estimation problem for time-varying parameters when no proper prior distribution is specified. The key ideas involve a combination of the information-form Kalman filter with the two-filter interpretation of the optimal...

We study the problem of an investor who buys an equity stake in an entrepreneurial venture, under the assumption that the former cannot monitor the latter's operations. The dynamics implied by the optimal incentive scheme is rich and quite different from that induced by other models of repeated...

The identifiability of reduced form econometric models with variable coefficients is investigated using the control theoretic concepts of uniform complete observability and uniform complete controllability. First, a variant of the state space representation of the traditional reduced form is...

In this paper we describe the important features of executive compensation in the US from 1993 to 2006. Some confirm what has been found for earlier periods and some are novel. Important facts about compensation are that: the compensation distribution is highly skewed; each year, a sizeable...

The agrarian unrest in the United States at the end of the nineteenth century is examined. This unrest is often viewed as stemming from the inability of farmers to adapt to changing conditions in world agriculture. This hypothesis is tested in the context of a distributed lag supply function....

The identification of time-varying coefficient regression models is investigated using an analysis of the classical information matrix. The variable coefficients are characterized by autoregressive stochastic processes, allowing the entire model to be case in state space form. Thus the unknown...

We consider the causes of international capital flows. Since capital flows are extremely persistent, we argue that their drivers must be persistent, too. We think the most compelling candidates are demographic trends, tfp differences and financial frictions. In this paper we focus primarily on...
