This study investigates the influence of the source of R&D funds and management ownership on R&D productivity. The lagged effect of the source of R&D funds on R&D output is investigated for a sample of US manufacturing firms in five industries over the 1996–99 period. Estimates based on 779 firm-years show that R&D productivity increases with the proportion of stock held by managers and directors of firms primarily in the Other Electronics industry. The estimates also show that recipients of government-sponsored R&D funds in the Chemicals industry have lower levels of output (sales) for each dollar committed to R&D. In addition, output for firms in the Chemicals industry worsens as management stockholding increases, implying an agency cost rationale for the observed difference in output. The implication is that firms with high manager-owner content are less productive with government-sponsored R&D than with company-financed R&D. The reported results suggest that potential agency costs should be incorporated in government-sponsored R&D contracts. It also suggests that the source of R&D funds should be disclosed and incorporated into the valuation of intangible assets attributable to research and development. 相似文献

A major gap in our understanding of the medieval economy concerns interest rates, especially relating to commercial credit. Although direct evidence about interest rates is scattered and anecdotal, there is much more surviving information about exchange rates. Since both contemporaries and historians have suggested that exchange and rechange transactions could be used to disguise the charging of interest in order to circumvent the usury prohibition, it should be possible to back out implied interest rates from exchange rates. The analysis presented in this article is based on a new dataset of medieval exchange rates collected from commercial correspondence in the archive of Francesco di Marco Datini of Prato, c. 1383–1411. It demonstrates that the time value of money was consistently incorporated into market exchange rates. Moreover, these implicit interest rates are broadly comparable to those received from other types of commercial loan and investment. Although on average profitable, the return on any individual exchange and rechange transaction did involve a degree of uncertainty that may have justified their non‐usurious nature. However, there were also practical reasons why medieval merchants may have used foreign exchange transactions as a means of extending credit. 相似文献

There have been claims that British capital was not well deployed in Victorian Britain. There was, allegedly, a lack of support for new and dynamic companies in comparison to the situation in Germany and the US. We find no evidence to support these claims. The London Stock Exchange welcomed young, old, domestic, and foreign firms. It provided funds to firms in old, existing industries as well as patenting firms in ‘new‐tech’ industries at similar costs of capital. If investors did show a preference for older and foreign firms, it was because those firms offered investors better long‐run performance. In addition, we show some evidence that investors who worked in the same industry and lived close to the firm going public were allotted more shares in high‐quality initial public offerings. 相似文献

We develop an optimizing life‐cycle model of retirement with perfect capital markets. We show that longer healthy life expectancy usually leads to later retirement, but with an elasticity less than unity. We calibrate our model using data from the US and find that, over the last century, the effect of rising incomes, which promote early retirement, has dominated the effect of rising lifespans. Our model predicts continuing declines in the optimal retirement age, despite rising life expectancy, provided the rate of real wage growth remains as high as in the last century. 相似文献

This article explores how far the emergence of public sector Equality Representatives represents a departure from a distinct radical model of union self‐organisation generated by the collective mobilisation of politically conscious identities, towards a more inclusive liberal model of equality based on abstract notions of ‘fairness’. 相似文献

Many nations have undergone significant trade liberalization even as they have increased their use of contingent protection measures. This raises the question of whether some of the trade liberalization efforts, at times accomplished through painful reforms, have been undone through a substitution from tariffs to non‐tariff barriers. Among the new forms of protection, antidumping is the most relevant. This paper examines whether the use of antidumping is systematically influenced by the reduction of applied sectoral tariffs in a sample of 29 developing and six developed countries from 1991 through 2002. Evidence is found of a substitution effect only for a small set of heavy users of antidumping among developing countries. There is no similar statistically significant result for other developing countries or developed countries. Robust evidence is also found of retaliation and deflection effects as determinant of antidumping filings across all subsamples. 相似文献

This article examines the impact of regulation and market-driven private actions on food safety performance in the meat and poultry industries. We find that private actions account for about 80% and regulation about 20% of the overall reduction in the share of samples of cattle and hog carcasses, ground beef, and broilers testing positive for Salmonella if all regulation and private actions were increased by identical amounts. 相似文献
