This paper investigates the susceptibility of futures markets to price manipulation in a two-period model with asymmetric information and “cash settlement” futures contracts. Without “physical delivery,” strategies based on “corners” or “squeezes” are infeasible. However, uninformed investors still earn positive expected profits by establishing a futures position and then trading in the spot market to manipulate the spot price used to compute the cash settlement at delivery. We also show that as the number of manipulators grows, profits from manipulation fall to zero. However, even in the limit, manipulation still has a nontrivial impact on market liquidity. More broadly, we interpret manipulation as a form of endogenous “noise trading” which can arise in multiperiod security markets.  相似文献

Traditionally, logistics and transportation problems have been addressed through mathematical modelling, operations research, and simulation, but criticism has emerged about their effectiveness to actually address real-life problems. This paper documents a case study whereby the road transport operations of a leading Mexican brewery were improved through lean thinking and waste reduction. Two lean-based principles and tools were combined: the Seven Transportation Extended Wastes and Transportation Value Stream Mapping. Three systematic steps were proposed to facilitate the implementation of improvement. Feasibility studies conducted in this research suggested that lean thinking is an effective alternative for the improvement of road transport operations. The findings of this research could be used as guidance for transport managers to improve road transport operations. This paper also expands the limited evidence of the application of lean thinking in road transport logistics and highlights the research areas where its application has been concentrated in this sector.  相似文献

A multiphase study involving 1,285 respondents was conducted to answer an important yet overlooked question: for a job requiring frequent informal communication with superiors, should an organization focus more on selecting employees with higher trait‐like willingness to communicate or on providing an environment where the flow of communication is easy and aided? We found support for the latter. Further, we observed that subordinates alter their communication behaviors based on the perception of superior's power, politics in the organization, and their own political skills. The study contributes to a better understanding of how situational variables affect subordinate‐superior upward communication. Implications of the study are also discussed. © 2016 Wiley Periodicals, Inc.  相似文献

Although blockchain has attracted a great deal of attention from academia and industry there is a lack of studies on acceptance drivers. This study explores blockchain acceptance by mining the collective intelligence of users on Twitter. It maps blockchain user acceptance drivers to technology acceptance constructs. The analysis shows that users are attracted by security, privacy, transparency, trust and traceability aspects provided by blockchain. On Twitter more discussions on blockchain benefits than on drawbacks. Initial coin offering (ICO) is extensively discussed. The study provides guidelines for managers and concludes by presenting the limitations of the study along with future research directions.  相似文献

In this paper, we explore the link between scientific and technical research and economic growth in China and USA over the sample period 1981–2012 using the extended Cobb–Douglas model with capital per worker and the quantity of scientific and technical journal articles (research publications) per worker. We examine the cointegration relationship and present the short-run and long-run results using the autoregressive distributed lag bounds procedure. Further, we examine the direction of causality between research publications per worker results and economic growth variables using the Toda and Yamamoto (J Econom 66(1–2):225–250, 1995) procedure. Our results indicate for both countries research publications per worker positively influence the output per worker both in the short-run and the long-run. The causality results for China indicate a bi-directional causality between research publications per worker and output per worker, duly emphasizing the mutually reinforcing effect. In case of USA, we note a unidirectional causation output per worker to research publications per worker indicating that output Granger cause research publications.  相似文献

Consumer innovativeness is a central variable in innovation diffusion and adoption literature. The foremost challenge confronted by investigators involved in innovation diffusion and adoption research is the problem of measuring the innovativeness construct. Furthermore, a scale measuring innovativeness towards self-service technologies (SSTs) adoption is required as SSTs have grown considerably in the last few decades. To this end, this study develops and validates a self-service innovativeness (SSI) scale applicable across a variety of SSTs. The study presents a series of six distinct phases describing the development and validation of a six-item, self-report scale. The innovativeness scale has been validated in different contexts, allowing comparisons across distinct samples (i.e., student vs. non-student sample) and different industries (i.e., retail and hospitality industries). The SSI scale presented in this paper is short, valid, reliable, and easy to administer in service domains.  相似文献

ABSTRACT

This study investigates differences between U.S. global and local brands in the Indian market. Attitudes toward American products and the brand equity of U.S. global and local casual apparel brand in the Indian market are examined. It is postulated that global and local brand influence brand equity, which is composed of brand image, brand awareness, emotional value, perceived quality, brand loyalty, and purchase intention. A total of 411 college students in India participated in the survey. Using repeated measures ANOVA, this study finds that Indian consumers perceive global and local brands differently based on brand equity.  相似文献

Contrary to the popular belief that objective knowledge (OK) (that is, what is actually stored in the memory) and subjective knowledge (SK) (that is, what individuals perceive they know) differently impact information search and information-processing behaviour, an empirical study conducted on 268 mutual fund (MF) investors suggests no significant difference in the impact of OK and SK on the width and depth of information search and information processing. The study suggests that OK and SK significantly positively impact the width and depth of information search and information-processing behaviour, however, no significant difference exists in the way they impact. The possible explanation put forward is that even though MF investors may suffer from self-deception (that is, pseudo expertise) and report high knowledge (that is, high SK), the impact of SK on actual investment behaviour is not significantly different from that of OK. The implications of the findings are also discussed.  相似文献

Whether common stocks provide a hedge against inflation has been long debated. This paper focuses on this question by investigating the relationship between inflation and stock returns in the short term and medium term and under different inflationary regimes using the UK data. Empirical evidence suggests that the UK stock market fails to hedge against inflation in the short term. However, in the medium term there is mixed results. Results from different inflationary regimes show that the relationship between inflation and returns varies in different regimes.  相似文献

This paper addresses three important questions. First, what are the trends, levels and sources of income inequality in India? Second, how have been the patterns of income mobility? And finally, exploring the relationship between income mobility and income inequality in the context of India. Results, based on recent India Human Development Survey (IHDS) longitudinal data, advocate that not only is income inequality very high, nonetheless, it has increased – mainly attributable to different income sources – in India. The paper also focused on whether or not this income mobility equalizes longer-term incomes. Results suggest income mobility has resulted in-albeit not robust- equalizing longer-term incomes. Thus, based on imperative findings, the paper suggests, the nature of longer-term well-being is crucial to designing policy interventions to effectively tackle inequality and in this context, economic mobility can be seen as an avenue to long-term equality.  相似文献
