We use the DATAMATION index of the top 50 domestic IT companies (1975–1995) to track persistence and change at the top of the sector. The trends that we uncover are increasing instability, rejuvenation (declining average age of entrants coupled with increasing average age of quitters), democratization (diminishing revenue inequality at the top) and growing supply‐side intertwining of sub‐sectors and industries within IT due to diversification by long‐term survivors. 相似文献

Summary. If only the strict part of social preference is required to be transitive then Independence of Irrelevant Alternatives implies
that there is a coalition containing all but one individual that cannot force x to be socially ranked above y for at least half of the pairs of alternatives (x,y).

Caplan holds that governments are Leviathans, seeking to extend their power by increasing government expenditures beyond the level preferred by voters. We extend Caplan's model by examining the real (percentage) growth rates of government. We also examine whether government size increases at an increasing rate as the minority party weakens. We find evidence that supports and fails to support the original Leviathan hypothesis. We also fail to support our extensions of Caplan's hypothesis. Furthermore, our significant and contrary results have intuitively appealing interpretations. From these results, we conclude that the impact of political party power on government spending is ambiguous. 相似文献

Monetary and fiscal policy interactions in a New Keynesian model with capital accumulation and non-Ricardian consumers 总被引:1,自引:0,他引:1
The paper examines simple monetary and fiscal policy rules consistent with determinate equilibrium dynamics in the absence of Ricardian equivalence. Under this assumption, government debt turns into a relevant state variable which needs to be accounted for in the analysis of equilibrium dynamics. The key analytical finding is that without explicit reference to the level of government debt it is not possible to infer how strongly the monetary and fiscal instruments should be used to ensure determinate equilibrium dynamics. Specifically, we identify bifurcations associated with threshold values of steady-state debt, leading to qualitative changes in the local determinacy requirements. 相似文献

Emmanuel Levinas Franois Bouchetoux Campbell Jones 《Business ethics (Oxford, England)》2007,16(3):203-207
This is a translation of ‘Socialité et argent’, a text by Emmanuel Levinas originally published in 1987. Levinas describes the emergence of money out of interhuman relations of exchange and the social relations – sociality – that result. While elsewhere he has presented sociality as ‘nonindifference to alterity’ it appears here as ‘proximity of the stranger’ and points to the tension between an economic system based on money and the basic human disposition to respond to the face of the other person. Money both encodes and effaces sociality, both designates and disguises social relations. It arises from the way that needs and interests are manifested in exchange relations, in what he calls the ‘interestedness’ of economic life. But interests are always already cut through by the fact that being is always ‘being with others’. Being is always ‘interbeing’. Interestedness is always confronted by disinterestedness, that is, by a sociality marked by the ‘goodness of giving’, attachment to and concern for the poverty of the other person. Levinas concludes with a discussion of sociality and justice, posing questions about the tension between the demand to respond to an Other immediately before me and at the same time to respond to the demands of an other Other (the third person) who also invites a response. 相似文献

The SEC and FASB recently expressed concerns that investors do not fully assimilate all of the information provided by complex and incomplete derivatives and other comprehensive income (OCI) disclosures. My evidence supports these concerns. Specifically, I examine the information content of unrealized cash flow hedge gains/losses for future profitability and stock returns. An unrealized gain on a cash flow hedge suggests that the price of the underlying hedged item (i.e., commodity price, foreign currency exchange rate, or interest rate) moved in a direction that will impair the firm's profits after the hedge expires. Consequently, I find that unrealized cash flow hedge gains/losses are negatively associated with future gross profit after the firm's existing hedges have expired. This association only holds after the firm has reclassified its hedges into earnings, and is weaker for firms that can pass input price changes on to their customers. Finally, investors do not immediately price the cash flow hedge information. Instead, investors appear surprised by future realizations of gross margin, consistent with the view that complex and incomplete disclosures delay pricing. These results are relevant to policymakers involved in the current FASB and IASB project designed to simplify the accounting and disclosure for derivatives and, in particular, cash flow hedges. 相似文献

In industrial markets many managers from marketing, technical service and production functions interact with customers. How should these managers be allocated to an evolving array of customers? This paper reports on the customer visits made by the managers of one packaging supplier. The visits of the marketing people seem related to the financial significance of the customer, whereas the technical visits are best understood by a ‘portfolio’ approach. At the same time many idiosyncratic and situational factors affect resource deployments. 相似文献

Regression tests of the expectations theory of the term structure typically reject the null hypothesis of orthogonality between implied forecast errors and the yield spreads. In the statistical literature on the term structure, these rejections are sometimes attributed to time-varying liquidity premia, and Engle et al . (1987) suggest that the ARCH-M model of time-variation in the liquidity premium may be sufficient to account for rejections of the expectations theory. We use non-parametric (kernel) regression to explore the regression test results on a number of data sets, and find some evidence of a persistent deviation from orthogonality for large absolute values of the spread. Incorporating ARCH-in-mean into models of the term premium indicates that this specification does explain significant time variation in liquidity premia, but the effect does not apepar to be sufficient to account for all of the deviations from orthogonality of forecast errors and spreads. 相似文献

This paper reports on the needs identified by three teachers during an investigation into their first experiences of implementing
technology in their primary classrooms. One part of one teacher's case is presented in detail to illustrate that the meanings
the teachers made of their experiences were related very closely to their beliefs about teaching and learning, to their understanding
of technology as a phenomenon and to the place they saw technology having within the whole curriculum. One particular outcome
of the investigation was that the teachers experienced a lack of knowledge of the scope and breadth of the technology learning
area, and as a consequence, faced challenges in planning for the successful implementation of activities. In response to this
particular need and to the many issues emanating from current research literature in technology education, the paper then
presents two models for conceptualizing and planning units of work in technology in primary classrooms. The models form frameworks
that may be useful to help structure thinking for authentic classroom planning and sequencing of lessons or learning experiences.
