This paper constructs updated measures of productive highway capital stocks at the total, Interstate, Non-interstate, and Local System levels to estimate the contribution of all highways (all public roads) to GDP growth. It presents three types of contribution to GDP growth estimates and an...

In a previous paper, the authors took the first step in their research on measuring the education function of government by estimating real output measures (Fraumeni, et. al. 2004). In this paper, chain-type Fisher quantity indexes for those output measures are calculated to be more consistent...

In this paper we estimate China's human capital stock from 1985 to 2007 based on the Jorgenson-Fraumeni lifetime income approach. An individual's human capital stock is equal to the discounted present value of all future incomes he or she can generate. In our model, human capital accumulates...

Both human capital and nonhuman capital play an important role in economic growth. Estimates of nonhuman (physical) capital exist for many more countries than for human capital. Recently there has been a significant increase in the number of countries for which estimates of human capital exist,...

We show how the value of a real option depends on corporate income taxes and the option's "debt capacity," defined as the amount of debt supported or displaced by the option. The value of the underlying asset must be an adjusted present value (APV). The risk-free rate of interest must be...

This paper develops a signaling model in which accounting information improves real investment decisions. Pure cash flow reporting is shown to lead to underinvestment when managers have superior information but are acting in shareholders' interests. Accounting by prespecified, "objective" rules...

We present a real-options model of takeovers and disinvestment in declining industries. As product demand declines, a first-best closure level is reached, where overall value is maximized by shutting down the .rm and releasing its capital to investors. Absent takeovers, managers of unlevered...

Morck, Yeung and Yu (MYY, 2000) show that R2 and other measures of stock market synchronicity are higher in countries with less developed financial systems and poorer corporate governance. MYY and Campbell, Lettau, Malkiel and Xu (2001) also find a secular decline in R2 in the United States over...

This paper develops a model to study how entrepreneurs and venture-capital investors deal with moral hazard, effort provision, asymmetric information and hold-up problems. We explore several financing scenarios, including first-best, monopolistic, syndicated and fully competitive financing. We...

This paper contrasts the "static tradeoff" and "pecking order" theories of capital structure choice by corporations. In the static tradeoff theory, optimal capital structure is reached when the tax advantage to borrowing is balanced, at the margin, by costs of financial distress. In the pecking...
