This paper investigates whether the recent wave of corporate restructuring in the United States has had a negative impact on research arid development investment by industrial firms. Using a newly constructed sample of about 2500 manufacturing firms from 1974 to 1987, I examine three major...

This document describes the panel of publicly traded United States manufacturing firms which was created and updated at the National Bureau of Economic Research from 1978 through 1988 within the Productivity Program. The panel consists of about 2600 large manufacturing firms with three to...

A "patent box" is a term for the application of a lower corporate tax rate to the income derived from the ownership of patents.

It is argued by many that one of the benefits of the patent system is that it creates a property right to invention that enables firms to obtain financing for the development of that invention. In this paper, I review the reasons why ownership of knowledge assets might be useful in attracting...

We analyze the use of intellectual property (IP) by firms in Chile over the decade 1995-2005 as the then middle-income country experienced rapid economic growth of 4.7 percent per year. We use a novel dataset that contains a combination of detailed firm-level information from the annual...

We develop a forward-looking profit model to estimate the depreciation rates of business R&D capital. By using data from BEA and NSF between 1987 and 2007, and the newly developed model, we estimate both constant and time-varying industry-specific R&D depreciation rates. The results comprise a...

We analyze the effect of patent thickets on entry into technology areas by firms in the UK. We present a model that describes incentives to enter technology areas characterized by varying technological opportunity, complexity, and the potential for hold-up due to the presence of patent thickets....

We revisit the relationship between market value and innovation in the context of manufacturing firms in a developing country, using data for Indian firms from 2001 through 2010. Surprisingly, we find that financial markets value the R&D investment of Indian firms the same or higher than it...

We use an extended version of the well-established Crepon, Duguet and Mairesse model (1998) to model the relationship between appropriability mechanisms, innovation and firm-level productivity. We enrich this model in several ways. First, we consider different types of innovation spending and...

Information about the success of a new technology is usually held asymmetrically between the research and development (R&D)-performing firm and potential lenders and investors. This raises the cost of capital for financing R&D externally, resulting in financing constraints on R&D especially for...
