Accounting for Innovation and Measuring Innovativeness: An Illustrative Framework and an Application by Jacques Mairesse and Pierre Mohnen. Published in volume 92, issue 2, pages 226-230 of American Economic Review, May 2002

I examine the effects of FCC regulation on the innovation and introduction of advanced telecommunications services in the United States. An interim of lighter regulation provides an "experiment" to test the regulatory regime's impact. The econometric model comprises an arrival process (for service innovation) followed by a duration process (for regulatory delay). The number of services the firms created during the interim is 60%-99% higher than the model predicts they would have created if the stricter regulation had still been in place. Overall, firms would have introduced 62% more services to consumers during the study period if the regulation had not been in place

We study the effects of financial innovation in a model of endogenous information acquisition. We determine the conditions under which the introduction of a derivative written on an existing stock increases or decreases the incentive to purchase information. We show that financial innovation produces some effects which hold across informational structures and others which differ. The former coincide with the few empirical results that are robust in the literature (effects on prices, risk premia, and volatility), while the latter coincide with the ones that differ experiment by experiment (effects on volume, correlation between volume and volatility, and market informational efficiency

This paper treats racial integration as an innovation in economic process in which economic entities find it advantageous to utilize potentially more productive inputs previously unavailable due to law, custom, or managerial discretion. Data on the racial integration of Major League Baseball and Atlantic Coast Conference basketball are employed to address this issue. The central question examined is which type of team integrated first—losers or winners? The results strongly support the idea that entrepreneurship trumps competitive rivalry; that is, winning teams led the process of racial integration

An important characteristic of any buyer‐supplier relationship is the amount and type of information that is exchanged between the contracting parties. Buyer‐supplier networks are characterized by greater information exchange than arm’s‐length transactions. This enhanced information exchange allows for greater production efficiency but increases the potential for information misappropriation. In this paper we characterize the set of innovations for which each of these forms of exchange relationships is efficient. We then explore the effect of an initial information linkage between the buyer and supplier. Such linkages increase the set of innovations for which networks are efficient. However, such linkages have a negative effect on the buyer’s incentive to innovate and an ambiguous effect on the supplier’s incentive to invest in flexible production techniques. Finally, we identify settings in which the buyer‐supplier surplus is greater with such linkages

We investigate the hypothesis that the combination of three related innovations—1) information technology (IT), 2) complementary workplace reorganization, and 3) new products and services—constitute a significant skill-biased technical change affecting labor demand in the United States. Using detailed firm-level data, we find evidence of complementarities among all three of these innovations in factor demand and productivity regressions. In addition, firms that adopt these innovations tend to use more skilled labor. The effects of IT on labor demand are greater when IT is combined with the particular organizational investments we identify, highlighting the importance of IT-enabled organizational change

We examine the interplay of markets, ethics and law, and rising demand for ethical behavior in a market driven society coping with the promise and peril of rapid technological innovation. We analyze the market affecting role of our Common Law/Rule of Law System, its adaptability to social need, and resultant legal and regulatory action promoting adherence to the spirit as well as the letter of the law. We provide examples of manager and firm harm from sanctions imposed despite adherence to “the rules.” Finally, we discuss competitive market-common law interplay in the coming era of the genome
