Some employers have begun to undertake a variety of initiatives, collectively termed value-based purchasing (VBP), which aim at factoring quality into the purchasing decision-making process when negotiating costs with providers and insurers. There is evidence that the VBP movement has begun gaining momentum; yet it is unclear whether employers are firmly committed to VBP principles. By surveying a national sample of employers, this study investigates the extent to which employers are currently engaged in VBP activities and also increases our understanding of barriers hampering the broader implementation of these activities.  相似文献

We develop Lancaster's model of consumer behaviour under product differentiation to analyse Schumpeterian creative destruction. Launching new products with novel characteristics enables firms to temporarily steal market share from rivals. Product launch is monitored by using trade marks, patents and research and development. The dataset covers a large sample of UK service and manufacturing firms. We find that stock market value is positively associated with own trade mark activity and trade mark‐active firms achieve significantly higher value‐added. Greater trade mark activity by competitors reduces net output of firms, but raises their stock market value. This is consistent with the Schumpeterian process of competition through innovation.  相似文献

We use a detailed panel data set of Swedish households to investigate the relation between their labor income risk and financial investment decisions. In particular, we relate changes in wage volatility to changes in the portfolio holdings for households that switched industries between 1999 and 2002. We find that households do adjust their portfolio holdings when switching jobs, which is consistent with the idea that households hedge their human capital risk in the stock market. The results are statistically and economically significant. A household going from an industry with low wage volatility to one with high volatility ceteris paribus decreases its portfolio share of risky assets by up to 35%, or $15,575.  相似文献

This paper surveys empirical studies employing trade mark data that exist in the economic literature to date. In the introductory section we summarise the theory of trade marks. Section 2 documents the use of trade marks by firms of different size and industry and by firms in several advanced countries, including Australia, the UK, and the USA. Section 3 reviews various attempts to gauge the function of a trade mark as an indicator of innovation and product differentiation. Section 4 surveys studies that have demonstrated firms' incentives to use trade marks, including transferring information to consumers, realising synergies between different types of intellectual property rights, strategies to raise rivals' costs and using trade mark portfolios as debt collateral. In Section 5, we provide an overview of the importance of trade-mark-use for firm survival and the association of trade marks with several dimensions of firm performance, including productivity and their ability to generate well-paid jobs.  相似文献

I examine whether independent directors with multiple board affiliations (IDMAs) trade off the interests of one fund relative to another (fund favoritism) or whether they benefit fund shareholders by increasing the level of the board's expertise. Using a sample of mutual funds affiliated with the top 55 fund sponsors from 2002 to 2008, I find that the presence of IDMAs is negatively related to performance/resource shifting across funds within fund families. IDMAs appear to decrease fund fees, increase the return gap associated with the unobserved actions of fund managers, and facilitate the transfer of information across funds in a fund family.  相似文献

This study examines the extent to which subnational regions can explain foreign affiliate performance in two host country settings, the United States and China, the world's two largest economies at polar ends of the economic spectrum (i.e., an advanced versus an emerging economy). Our results suggest that the subnational region is significant in explaining foreign affiliate performance, thus confirming its importance as an additional unit of analysis for firm performance. This study also shows that the effects of subnational region are far stronger in China than they are in the United States, thus suggesting that regional differences are more critical in their explanatory power for firm performance in emerging economies than they are in advanced economies.

Scenarios and counterfactuals are two types of modal narrative. Modal narratives concern themselves with contingency and determinism: with questions of possibility and necessity. While scenarios are future-oriented, focused on what might yet be, counterfactuals are narratives of what might have been. Despite this fundamental temporal difference, consideration of the theoretical and philosophical underpinnings of modal narratives as a genre enables us to elucidate some critical issues concerning scenarios as a foresight methodology. In particular, the scenario literature has tended to avoid extended discussion of its implicit assumptions concerning causation, necessity, possibility and contingency. By confronting the modal nature of foresight methodologies more explicitly, the futures community may begin to lay more secure philosophical foundations for their deployment.  相似文献

The ability of futures markets to predict subsequent spot prices has been a controversial topic for a number of years. Empirical evidence to date is mixed; for any given market, some studies find evidence of efficiency, others of inefficiency. In part, these apparently conflicting findings reflect differences in the time periods analyzed and the methods chosen for testing. A limitation of existing tests is the classification of markets as either efficient or inefficient with no assessment of the degree to which efficiency is present. This article presents tests for unbiasedness and efficiency across a range of commodity and financial futures markets, using a cointegration methodology, and develops a measure of relative efficiency. In general, the findings suggest that spot and futures prices are cointegrated with a slope coefficient that is close to unity, so that the postulated long-run relationship is accepted. However, there is evidence that the long-run relationship does not hold in the short run; specifically, changes in the spot price are explained by lagged differences in spot and futures prices as well as by the basis. This suggests that market inefficiencies exist in the sense that past information can be used by agents to predict spot price movements. A measure of the relative degree of inefficiency (based on forecast error variances) is then used to compare the performance of different markets. © 1999 John Wiley & Sons, Inc.
