We study a model of network formation and start-up financing with endogenous entrepreneurial type distribution. A hub firm admits members to its network based on signals about entrepreneurs’ types. Network membership is observable, which allows lenders to offer different interest rates to...

The recent fall of labor's share of GDP in numerous countries is well-documented, but its causes are poorly understood. We sketch a “superstar firm” model where industries are increasingly characterized by “winner take most” competition, leading a small number of highly profitable (and...

Financial constraints are an important impediment to the growth of small businesses. We study theoretically and empirically how the financial constraints of agents affect their decisions to exert effort, and, hence the organizational decisions and growth of principals, in the context of...

We view the entrepreneur as an agent who possesses human capital in the form of specific skills or talents. When she starts a firm, her human capital is essential to the firm and it has substantial private value. The entrepreneur transforms her human capital over time into what we call...

In this article, we analyse the interactions between financial and start-up decisions in an oligopolistic framework, where firms compete to enter a new market. We show that preemption can substantially reduce the negative effects of credit rationing on start-up investment decisions

We explore the effect on U.S. real GDP growth of the sharp and sustained decline in the global price of crude oil and hence in the U.S. price of gasoline after June 2014. Our analysis suggests that this decline produced a cumulative stimulus of about 0.9 percentage points of real GDP growth by...

We estimate growth rates of real incomes in the U.S. by quintiles using the Congressional Budget Office's (CBO) post-tax, post-transfer data as basis for the period 1979-2011. We improve upon them by including only the present value of earnings that will accrue in retirement and excluding items...
