abstract Efficient market models cannot explain the high level of trading in financial markets in terms of asset portfolio adjustment. It is presumed that much of this excessive trading is irrational ‘noise’ trading. A corollary is that there must either be irrational traders in the market or rational traders with irrational aberrations. The paper reviews the various attempts to explain noise trading in the finance literature, concluding that the persistence of irrationality is not well explained. Data from a study of 118 traders in four large investment banks are presented to advance reasons why traders might seek to trade more frequently than financial models predict. The argument is advanced that trades do not simply occur in order to generate profit, but it does not follow that such trading is irrational. Trading may generate information, accelerate learning, create commitments and enhance social capital, all of which sustain traders' long term survival in the market. The paper treats noise trading as a form of operational risk facing firms operating in financial markets and discusses approaches to the management of such risk.  相似文献

In the e-Retail industry, a well-designed IT infrastructure is essential in creating a tightly integrated value chain and delivering high quality service. With intense competition for market share and profits, information systems and technology (IST) sourcing decisions are becoming increasingly important to e-Retail firms to support continued growth and market responsiveness. Drawing on the contingency theory, we examine organizational and environmental factors that influence an e-Retailer's IST sourcing strategy of make versus buy in enabling its value chain activities, and we also look at firm-level performance impacts of IST sourcing decisions that involve bundling across value chain activities. We test the proposed model and hypotheses using a panel data set of 307 firms over the period of 2006–2010. The results show that firms that make transformative IT investments tend to source a smaller portion of IST for their e-Retail value chain activities than firms that pursue automate or informate as their strategic role for IT investment. Capabilities are positively associated with IST sourcing. Firms experienced in e-Retail are more likely to build rather than buy their IST. In addition, we find mimicking behavior for IST sourcing among firms in the same merchandizer category. We find that IT strategic role is strongly associated with growth metric, whereas sourcing decisions predominantly impact operational performance measures. There is partial evidence that alignment between IT strategic role and IST sourcing decisions results in better performance effects. Moreover, complementary IST sourcing of synergistic marketing and sales activities positively impacts Web sales and conversion rate, but the sourcing combination of logistics, operations, and sales activities is associated with lower Web sales and conversion rate.  相似文献

Los autores comparan las normativas sobre vacaciones y licencias susceptibles de facilitar el equilibrio entre vida profesional y familiar de Australia, Canadá, República de Corea, Estados Unidos, Europa occidental y Japón utilizando un índice compuesto para clasificarlas. Los Estados Unidos figuran en último lugar: la concesión de vacaciones anuales al trabajador no es obligatoria y las licencias por motivos familiares se limitan a 12 semanas al año. Este bajo nivel de reglamentación podría deberse, según los autores, a una concepción mercantilista del empleo sumada a la creencia de que empleador y trabajadores tienen idéntica capacidad de negociación, visión no compartida por las demás democracias industrializadas.  相似文献

Real assets are usually valued by computing the stream of profits they can bring to a price‐taking firm in a liquid market. This method ignores market fundamentals by assuming that all the relevant information is included in the spot price. Our article analyses the bias resulting from such an approach when the market is imperfectly competitive. We propose a stylised two‐period model of the natural gas market with no uncertainty, focusing on strategic interactions between two types of oligopolistic players—pure traders and suppliers with downstream customers—who have access to storage. We show that the true value of storage capacity is not the same for traders and for suppliers. Comparing the latter value with the traditional price‐taking valuation reveals a systematic bias that tends to induce underinvestment.  相似文献

  • Nowadays, not‐for‐profit organizations and charities face the ageing of donors and a growing debate over monetary donation collection methods. They need to find solutions to attract younger generations of donors. Could this be done using the same methods applied to older generations? This present research investigates social representations (SRs) of giving by younger generations to understand how not‐for‐profit organizations and charities should approach them. The study focuses on SRs of a French sample of 276 individuals from Generation Y born between 1979 and 1991. It uses the free association technique. The results show paradoxical representations of giving. Institutionalization of giving is salient as representation of it as a freely consenting act. The paradox relies also in the strong presence of a relationship with others that parallels the gift as an individualistic choice.
  • Generation Y individuals appear to be sociable, yet they evoke more sharing and solidarity than charity. Institutionalized forms of giving, particularly via charities and not‐for‐profit organizations, are rejected. These individuals seem to express their individuality through practices that resemble sharing rather than giving. From a managerial point of view, these results shed light on the factors liable to cause members of this generation to give, such as (i) the use of social networks, (ii) appealing to pleasure, festivities and efficiency rather than to guilt and duty, and (iii) encouragement to “work within the not‐for‐profit organization”.

Utilitarian foundations for limited government are shaky insofar as they assume rational and consistent individuals. Recently economists’ assumption of rational actors has come under sustained attack. Behavioural economics has suggested that people are plagued by irrational biases and inconsistencies. These developments have led to a post‐utilitarianism which is held to justify paternalistic interventions by the state via ‘sin taxes’, direct bans or new obligations. Individual responsibility is seriously undermined, as is faith in markets. Supporters of individual freedom need to move away from utilitarian reasoning, reassert core values of autonomy and responsibility, and define strict limits on the scope of government intervention.  相似文献

ABSTRACT The paper examines effects of executives’ orientations on crisis management awareness and practices, drawing on the simplicity and paradox management theories. It is suggested that a focus on single‐sided management constitutes an antecedent of crisis proneness. Employing a set of key corporate domains and based on a holistic organizational approach, the study aims at assessing the extent to which companies are crisis prone or prepared. In a sample of 82 Istaeli business and not‐for‐profit organizations it was found that human resource management, strategy, structure, and unlearning factors significantly predicted crisis preparedness. These results suggest that unlearning, despite a mere allusion to this correlate in the simplicity and paradox management theories, correlates better with crisis preparedness. By contrast, traditional strategy‐related and structural effects were marginally related to crisis management policies. Implications and suggestions for further research are proposed.  相似文献

The article analyzes the interaction between employee ownership, HRM policies and practices, and HRM outcomes in what was the world's biggest industrial worker cooperative for decades, and now defunct, Fagor Electrodomésticos. Using longitudinal internal data and detailed interviews with key stakeholders, this paper sheds light on how employee ownership conditioned HRM policies. HRM outcomes—such as job satisfaction and absenteeism—are also analyzed over a long period of time. Chronic nepotism when recruiting new members, failures in the training policy, impoverished and Taylorist working systems, and reverse dominance hierarchies are analyzed as factors that increased free riding and caused low satisfaction and the disengagement of working members. This case study contributes to the literature on HRM and worker cooperatives as it provides some insights that are rarely found in that literature. It also provides guidance to worker cooperatives about increasing the fit between employee ownership and HRM policies and outcomes.  相似文献

This paper develops a method to estimate the U.S. output gap by exploiting the cross‐sectional variation of state‐level output and unemployment rate data. The model assumes that there are common output and unemployment rate trend and cycle components, and that each state's output and unemployment rate are subject to idiosyncratic trend and cycle perturbations. I estimate the model with Bayesian methods using quarterly data from 2005:Q1 to 2018:Q2 for the 50 states and the District of Columbia. Results show that the U.S. output gap reached about negative 4.6% around the years of the Great Recession and was about 0.9% in 2018:Q2.  相似文献
