This paper examines three sets of explanations for variations in the strength of patent protection across sixty countries and a 150-year period. Wealthier nations are more likely to have patent systems, to allow patentees a longer time to put their patents into practice, and to ratify treaties assuring equal treatment of other nations. But they are also likely to charge higher fees and limit patent protection in some important ways. Countries with democratic political institutions are consistently more likely to have patent protection appear to be determined by historical factors. The origin of a country's commercial law appears particularly important in explaining the presence of restrictions on patentees' privileges and discriminatory provisions against foreign patentees.

ABSTRACT This paper empirically examines patents for financial formulas and methods, whose patentability was recently confirmed in the litigation between State Street Bank and Trust and Signature Financial Group. The number of such filings and awards has been accelerating. Patent filings by academics have been very infrequent, which appears to be a consequence of a lack of awareness or interest on the part of faculty members, rather than any fundamental unsuitability of their research for patenting. The failure to cite academic research in this area appears to be problematic and may reflect patent examiners' limited exposure to finance research and patents.

This article examines the representation of venture capitalists on the boards of private firms in their portfolios. If venture capitalists are intensive monitors of managers, their involvement as directors should be more intense when the need for oversight is greater. I show that venture capitalists' representation on the board increases around the time of chief executive officer turnover, while the number of other outsiders remains constant. I also show that distance to the firm is an important determinant of the board membership of venture capitalists, as might be anticipated if the oversight of local firms is less costly than more distant businesses.

The economics of partnerships have been of enduring interest to economists, yet it is not clear what profit sharing within a private partnership should look like. We examine over 700 private equity partnerships and show that the allocation of fund economics to individual partners varies drastically, even among the most senior partners, and appears divorced from past success as an investor, being instead related to status as a founder. A smaller share of carried interest and ownership—and inequality in fund economics more generally—is associated with departures of senior partners which, in turn is negatively related to the funds’ ability to raise additional capital.

This paper presents the theory that managers can use the liquidity of securities as a choice variable to screen for deep-pocket investors, those that have a low likelihood of facing a liquidity shock. We assume an information asymmetry about the quality of the manager between the existing investors and the market. The manager then faces a lemons problem when he has to raise funds for a subsequent fund from outside investors, because the outsiders cannot determine whether the manager is of poor quality or the existing investors were hit by a liquidity shock. Thus, liquid investors can reduce the manager's cost of capital in future fundraising. We test the assumptions and predictions of our model in the context of the private equity industry. Consistent with the theory, we find that transfer restrictions on investors are less common in later funds organized by the same private equity firm, where information problems are presumably less severe. Also, partnerships whose investment focus is in industries with longer investment cycles display more transfer constraints. Finally, we present evidence consistent with the assumptions of our model, including the high degree of continuity in the investors of successive funds and the ability of sophisticated investors to anticipate funds that will have poor subsequent performance.

Patents and citations are powerful tools increasingly used in financial economics (and management research more broadly) to understand innovation. Biases may result, however, from the interactions between the truncation of patents and citations and the changing composition of inventors. When aggregated at the firm level, these patent and citation biases can survive popular adjustment methods and are correlated with firm characteristics. These issues can lead to problematic inferences. We provide an actionable checklist to avoid biased inferences and also suggest machine learning as a potential new way to address these problems.

Beginning in the late 1980s, American corporations began increasingly linking the compensation of central research personnel to the economic objectives of the corporation. This paper examines the impact of the shifting compensation of the heads of corporate research and development. Among firms with centralized R&D organizations, a clear relationship emerges: more long-term incentives (such as stock options and restricted stock) are associated with more heavily cited patents. These incentives also appear to be associated with more patent awards and patents of greater originality. Short-term incentives appear to be unrelated to measures of innovation.

The consequences of providing public funds to financial institutions remain controversial. We examine the Community Development Financial Institution (CDFI) Fund’s impact on credit union activity, using hitherto little studied U.S. Treasury data. The CDFI Fund grants increase lending at credit unions by 3%. For every dollar awarded, 45 additional cents are loaned out to borrowers in the first year, and up to an additional $1.60 is loaned out within three years. Delinquent loan rates also increase slightly. Our panel results are supported by a broadband regression discontinuity analysis. Politics does not seem to play a role in allocating funding. (JEL G28)
