We propose a general theory of innovation that illustrates the relative benefits of performing process versus product R&D when firm size is endogenous. A firm's size, scope, and R&D portfolio are shown to reflect the same underlying characteristic of the firm, namely manufacturing efficiency. We demonstrate that efficient firms become larger, have greater scope, and perform more of both process and product R&D. In light of decreasing returns to R&D, this implies small firms obtain more product innovations per dollar of R&D than large firms, which is consistent with evidence we present that small firms are more innovative than large firms as they obtain more patent counts and citations per dollar of R&D.  相似文献

Starting from a comparison of Josef Steindl's observations on the problems of the financing of small firms, with the implications of the Modigiani – Miller approach to financial structure, this paper investigates relationships between financial leverage and operating leverage by the application of option pricing theory to the value of a firm's debt. Drawing on possible differences between the second-hand break-up value and the present value of the flow of earnings from a firm's assets, it suggests linkages between production structure and firm financial structure. It then extends these results to resolving the problems of providing market financing for the creation and evolution of small firms in industrialized and transforming economies.  相似文献

Abstract

This paper investigates the (re-)establishment of central banking in West Germany after 1945 and the history of the Bundesbank Act of 1957. The main focus is on the early emphasis on central bank independence, which at the time represented a German peculiarity. The paper inquires whether contemporary German economic thought may have provided a theoretical case for this peculiar tradition and scrutinizes the political calculus that motivated some key actors in the play. Contrary to conventional wisdom, important contradictions between the postulate of central bank independence and Ordoliberalism are identified.

This study employs daily data to examine the effects on Eurocurrency and onshore returns of the May 21, 1981 imposition of exchange controls by French President Mitterand. Prior to this time, transaction costs explain the average onshore deviations from covered parity; however, these averages ignore short-lived political risk premia which emerged just before the imposition of controls. As expected, there is no evidence of political risk of Eurocurrency markets. Yet when exchange controls were in effect, premia in excess of transaction costs surfaced on nonfranc Eurocurrency deposits at the time of devaluations of the franc within the EMS. [431]  相似文献

Cross-section data on secondary level student choices provide evidence on factors influencing the decision to study economics. Such evidence makes a key contribution to the broader debates on why student numbers have been falling in economics and why women are reluctant economists. Greater mathematical aptitude and prior knowledge of the subject influence the decision to study economics, and a significant effect is attributable to relative underachievement in economics. There are also significant peer group and teacher effects. Female students are more likely to study economics when there is a critical mass of women studying the subject. There is a positive role model effect of female teachers—although this does not carry over to the decision to continue with economics at the university.  相似文献

Concerns about consumers’ ability to manage their finances have triggered a range of proposals, including interventions aimed at elementary school students. The goal of these approaches is to improve lifelong economic decision making, but the evidence supporting their efficacy is thin. In this article, the authors discuss the trend toward elementary financial education and propose a framework for developing evidence-based programs. They emphasize the need for understanding the underlying mechanisms that facilitate the translation of student knowledge into the ability to make sound economic decisions over the life course. The framework illustrates the importance of articulating the intended mechanisms and effects of education programs. This focus on mechanisms will not only facilitate the evaluation of individual programs, but also the synthesis of evidence across interventions.  相似文献

We examine the relationship between the administrative enforcement of environmental regulation, ethnic heterogeneity, and other community characteristics in New Jersey and New York. We find that the percentage of non-white population in a community is positively related with administrative penalties imposed on violators. However, penalties are lower in more ethnically diverse communities. This result may be due to the fact that these communities are less likely to coordinate to create solidarity across ethnic groups and demand stronger enforcement.  相似文献
