This article examines the introduction of new process technology into a local labour market in the late 1980s and relates variations in adoption rates to establishment characteristics. The authors highlight the contrasts in the employment outcomes and training requirements in adopting and non-adopting establishments and find that 'adopters' expect more changes in employment, more skills shortages and have a greater awareness of future training needs.  相似文献

In this article, the pattern of occupational segregation by sex in the UK between 1979 and 1989 is explored through the decomposition of the new Karmel Maclachlan index. Over the upturn, 1983–89, integration of the sexes, as measured by the Composition Effect occurred faster for full-time employment than total (full-time and part-time) employment. On the other hand, integration, in general, proceeded more slowly over the downturn of 1979–83 but total employment showed a more rapid rate of desegregation than full-time employment. Further analysis of the index, based on notional redistributions of part-time and full-time employment, confirms that part-time employment appears to be disproportionately responsible for the overall level of occupational sex segregation and to inhibit its decline over the upswing. These results are attributed to the different labour supply behaviour of males and females and the propensity of employers to treat part-time employees as a flexible reserve. Policies are outlined to counteract both the unequal treatment of part-time workers, particularly women, and the allocative inefficiency caused by the growth of part-time employment, relative to full-time employment.  相似文献

Are Crop Yields Normally Distributed? A Reexamination   总被引:2,自引:1,他引:2  
This article demonstrates that normality test procedures that include individual detrending of short-term panel data can severely reduce the power of normality tests and strongly bias normality tests in a Type II direction. An alternative error component implicit detrending procedure is suggested that demonstrates higher power for the distributions examined. Both procedures are applied to a large data set with normality of yield residuals being rejected. Assuming normality is shown to reduce potential premium rates for a large number of producers in an existing crop insurance product.  相似文献

We study corporate website disclosures in the U.S. and Taiwan, two countries with different regulatory and market environments, to provide insights into the uniformity of website content and its contribution to the information environment. We observe significant variation in content both within and between the two countries. U.S. firms with higher analyst following tend to create more transparent financial information environments and provide disclosures that are complementary to analysts’ analyses through their corporate websites. They also tend to provide easier access to investor relations (IR) services if analyst coverage is light or nonexistent. However, neither effect is true in Taiwan where the securities analysis industry is less mature. Individual investors have greater ownership share in U.S. firms with more information about IR services on their websites; however, their ownership share drops as financial disclosure on the firm’s website increases, consistent with institutions diluting individual ownership in firms with more transparency in financial reporting. In Taiwan, however, institutions dilute individual ownership share in firms with less financial information and more trading information on their websites. These results are consistent with Barber et al.’s (2009) findings that institutions find Taiwan firms that attract the aggressive, speculative trading of individuals to be extremely profitable investments. Website disclosures in both countries have some effect on the stock-price response to mandatory earnings releases, but their impact is greater in the U.S. Our findings indicate that website disclosures contribute to the information environment and are related to the degree of interest in the firm by sophisticated market participants. Thus, they provide insights to regulators of both countries as they seek to improve disclosure and “level the information playing field.”  相似文献

Absorptive capacity (ACAP) has long been used in the research of technology firms as an indication of knowledge acquisition. This paper links knowledge input using new product introductions (NPI), to commercial output, addressing one of the key criticisms of research and development expenditures as a measure of an organization's effort. We propose that firms with a strong basic science foundation such as biology and chemistry seek to advance their scientific knowledge in addition to developing and selling innovative products. In contrast, corporations with a more applied focus forego fundamental scientific advancement and concentrate their actions on the development of innovative products. Results from a sample of 487 firms over a 10‐year period indicated that firms with an applied science foundation had greater numbers of NPIs, both breakthrough and innovative, suggesting that a solutions‐based approach had greater value in terms of innovative output. The pursuit of science may build knowledge, but a clear link between increased ACAP and innovative output was not found. Our results also suggest that basic science firms have a positive relationship with both breakthrough and incremental NPIs using merger and acquisition activities. Applied science firms found university alliances useful in generating NPIs.  相似文献

The authors deal with the restructuring of undergraduate economics instruction at Moscow State University (MSU) since 1989. They examine how closely the reforms at MSU are mirrored by changes at Belarus State University in Minsk and at Kiev State University. They also consider, and often offer an “insider's” perspective on, several issues related to curriculum reform that go beyond what can be determined from published curriculum guides. Specifically, they consider such issues as the training and retraining of faculty members who teach courses in these departments, the use of translated Western textbooks versus locally developed textbooks, and problems that arise in departments where some faculty members teach Western economics but others continue to teach Soviet-style economics.  相似文献

Since 1995, managers of thousands of firms have voluntarily disclosed the expected date of their firm's next quarterly earnings announcement to Thomson Financial Services Inc. These disclosures are approximately 500% more accurate than the simple time–series expected report dates used in prior accounting research. These disclosures are also informative. On average, managers who miss their own expected date eventually report earnings that fall about one penny per share below consensus forecasts for each day of delay. Investors respond by sending the price of late–announcing stocks down at the missed expected report date and continue to send them down as the reporting delay lengthens, consistent with our "day late, penny short" result. Despite this, we find that the market response at the time earnings are announced still depends on whether the announcement is early, on time, or late relative to the firm's own expected report date.  相似文献

We study a firm's decisions to engage in socially responsible activities, voluntarily report on them, and purchase external assurance of the report. In our signaling model, neither firm type nor the level of activity is observed. We show that if voluntary assurance is not too expensive, the firm that engages in more socially responsible activities purchases external assurance and thus “selects” a separating equilibrium. As a result, CSR reports can be used to infer the level of activity and this causes all firms to engage in more socially responsible activity. Further, when voluntary assurance is required to support a separating equilibrium, greater monitoring by social activists increases the chosen quality of voluntary assurance—voluntary assurance and monitoring by social activists are complements, not substitutes.  相似文献

A Dynamic Model of Network Formation   总被引:1,自引:0,他引:1  
Network structure plays a significant role in determining the outcome of many important economic relationships; therefore it is crucial to know which network configurations will arise. We analyze the process of network formation in a dynamic framework, where self-interested individuals can form and sever links. We determine which network structures the formation process will converge to. This information allows us to determine whether or not the formation process will converge to an efficient network structure.
