Despite the increasingly multinational nature of the workplace, there have been few studies of the convergence and divergence
in beliefs about ethics-based leadership across cultures. This study examines the meaning of ethical and unethical leadership
held by managers in six societies with the goal of identifying areas of convergence and divergence across cultures. More specifically,
qualitative research methods were used to identify the attributes and behaviors that managers from the People’s Republic of
China (the PRC), Hong Kong, the Republic of China (Taiwan), the United States (the U.S.), Ireland, and Germany attribute to
ethical and unethical leaders. Across societies, six ethical leadership themes and six unethical leadership themes emerged
from a thematic analysis of the open-ended responses. Dominant themes for ethical and unethical leadership for each society
are identified and examined within the context of the core cultural values and practices of that society. Implications for
theory, research, and management practice are discussed. 相似文献

With the launch of the original iPhone, Apple redefined the “smartphone” product category and accelerated the convergence
of traditional mobile telephony, Internet services, and personal computing into a new industry. As these sectors merge into
a single device, formerly separate industry architectures and their constituent firms are being forced into direct competition.
We test theories of industry architecture and technological platforms regarding their ability to explain the strategies of
key entrants in navigating the transition. We analyze in detail the actions and strategies of four major competitors, including
Apple, Google, Microsoft, Nokia, and, more briefly, Research in Motion and HP/Palm, from the framework of technological platform
theory. Our analysis suggests that currently some competitors are following traditional platform strategies, but that Google
and Apple appear to have adopted strategies at odds with platform literature. We examine how the dynamics of this convergence
may lead to a reconsideration of certain tenets of platform theory. 相似文献

Die Netzstrukturen im Bereich der Telekommunikation entwickeln sich weiter und erfordern neue Investitionen. Die notwendige Regulierung kann dabei verschiedene Formen annehmen und zu unterschiedlichen Zeitpunkten ansetzen. Die Autoren beschreiben die Netzinfrastruktur in Deutschland und zeigen die Ergebnisse der Regulierungsvarianten auf. 相似文献

This article analyzes efficiency and total factor productivity (TFP) change of large agricultural enterprises during their transition to a market economy in Ukraine. Efficiency is calculated by Data Envelopment Analysis and productivity change is measured by the Malmquist Productivity Change Index in the period between 1990 and 1999. On average, TFP declined by 6% annually, dropping a total 42%. The main reason for the observed TFP decline is a decrease in technical efficiency, which is found to be remarkably significant. At the same time there is a high variation among individual enterprises: the distribution of efficiency scores widens, which indicates that the farms diverge with respect to their economic performance. A Tobit regression analysis is conducted in which efficiency scores are related to factors such as farm type, farm size, initial conditions, and legal form. 相似文献

High yield bond investors spend a great deal of time studying covenants. They even hire specialized consultants to help them interpret the dense language of indentures. But for all that, does a company's decision to offer strong rather than weak covenants—or to offer covenants at all—have a measurable impact on its borrowing costs? There is surprisingly little evidence that variation in credit risk premiums reflects the presence or absence of covenants. Taking advantage of a newly available kind of data—Moody's Investors Service's Covenant Quality (CQ) ratings, which were initiated in 2011—the authors studied each newly issued U.S. high yield bond beginning in 2011 using Moody's CQ ratings, where a rating of “1” represents the strongest covenant rating and “5” the weakest. The authors hypothesize that if investors are willing to pay for covenant protection, bonds with weak CQ scores should have spreads that are higher, on average, than the medians of the bonds in their rating group. What they found, however, was that even bonds rated CQ5, indicating negligible protection, had spreads that were only 9.54 basis points higher than the median of companies with the same credit rating. The authors also found, contrary to their initial supposition, that higher yields were associated with stronger covenants, suggesting that investors demand more protection on issues they view as having greater credit risk than other equivalently rated issues. 相似文献

Much of the public discussion of the food price crisis has focused on the sharply increased use of food commodities for biofuel production, framing debate in simple food versus fuel terms. Reality is more complex. Multiple forces drove food prices to high levels and, according to findings we report in this article, these forces will sustain high prices over the medium term. We also find that the distinction between high world prices for food commodities and the consumer costs of food is an important one to make. Food consumers do not buy raw food commodities at international prices. The degree to which the price of traded food commodities and the price of food are related depends on a long list of factors, most of which operate to dampen price transmission. In the search for appropriate policy response, it is essential to measure consumer effects correctly and to apportion properly the causes of current high prices. 相似文献

The Land Use Scanner (LUS) is a decision support system for land use planning that is widely used in the Netherlands. The model yields solutions that have a high resolution (500×500 m) and reflect economic equilibrium in the land market, in which eighteen types of land use and nine aggregated habitat types competitively bid for locations. Here, an extension to the LUS is presented that enables the internalisation of environmental externalities. The focus in this study is on two important externalities, namely ammonia emissions from agriculture and habitat fragmentation. We simulate four IPCC-based land use scenarios and assess the level of fragmentation of the nine habitat types. We also perform sensitivity analyses in the most market-oriented scenario on the effectiveness of market-based instruments in promoting more efficient land allocation. The simulation results suggest that particularly the habitat type ‘rain-fed mires and bogs’ is susceptible to fragmentation. The sensitivity analyses show that internalising the damage costs of fragmentation resulted in smaller changes in land allocation than internalising those of nitrogen deposition. For both instruments, the policy effort was large in relation to the efficiency gains in land allocation. 相似文献

This paper looks at the optimal location of new forests in a suburban region under area constraints. The methodology takes into account use benefits, non-use benefits (both bequest and existence values), opportunity costs of converting agricultural land, as well as planting and management costs of the new forest. The recreational benefits of new forest sites are estimated using function transfer techniques. We show that the net social benefit of the total afforestation project varies up to a factor 6. The recreational value of a site varies considerably with the available substitutes. 相似文献
