In the presence of a non-constant marginal cost and demand uncertainty, we show that an output increase is no longer a necessary condition for welfare to increase following the introduction of third-degree price discrimination. We thus highlight the existence of an effect that might offset the well known output and misallocation effects of price discrimination. We propose a specific example where this is indeed the case.  相似文献

Collaborative spatial decision making (CSDM) involves multiple stakeholders making strategic decisions based on spatial data. Current CSDM tools have been exploring different ways to integrate spatial data with collaboration, distribution and mobility. Notably, decision-making support has not seen the same level of attention. This paper discusses the challenges raised by the integration of decision-making models in CSDM tools. We review a large collection of decision-making models using three different views: sequential, dynamic and continuous. From this review we derive a conceptual model and a set of functional requirements necessary to integrate decision-making support in CSDM tools. The conceptual model highlights the importance of several functions in decision-making processes: representing problems, finding alternatives and making choices (sequential view); classification and communication (dynamic view); and perception, comprehension and projection (continuous view). The paper also describes a prototype developed to validate the model. The paper provides two main research contributions: a unified view of decision-making support and an innovative CSDM tool blending spatial data with decision-making support.  相似文献

This article examines the effect of improvements in the quality of International Financial Reporting Standards (IFRS) on the level of earnings management. In order to achieve this aim, we study the accounting quality of German listed companies through discretionary accruals yielded from 1998 to 2006. We assess the effectiveness of efforts by the International Accounting Standards Board to improve IFRS by using two indices that consider the revision process of the standards, and their mandatory application. Our results indicate that the improvement of accounting standards quality significantly reduces the level of reported negative discretionary accruals of the German listed firms during the period of analysis, once incentive variables are controlled. Further, companies gradually assume the quality of the new standards from the moment they can be voluntarily applied.  相似文献

Human–computer interaction (HCI) design generally involves collaboration from professionals in different disciplines. Trained in different design education systems, these professionals can have different conceptual understandings about design. Recognizing and identifying these differences are key issues for establishing shared design practices within the educational community. Contributing to this understanding, we examined whether and how two different populations of students have different knowledge structures with respect to HCI design. We adopted the romantic, conservative and pragmatic dimensions, previously investigated in the related research, to elucidate those differences. This paper compares one specific type of design artefact—conceptual frameworks—created by groups of students with different educational backgrounds: Arts and Engineering. It was based on a set of 22 criteria divided by two main domains: scheme (addressing form) and realm (focusing on contents). The obtained results show that students with background in Engineering (1) focus more on the product of design; (2) rely less on conceptual frameworks to guide the design process; and (3) produce artefacts that are more constrained in terms of signal-to-noise ratio, definition of a symbolic system, and information organization and shaping. We suggest that conceptual frameworks serve to communicate and understand design practice. We note that Engineering students seem to be more susceptible to fixation than Arts students and suggest that an emphasis of reflection-in-action could help compensating this problem.  相似文献

The importance of the automotive industry in the global economy is widely recognised. The sector has undergone enormous changes in order to prepare for the fierce competition of the 21st century. Among these transformations, the most relevant are those technologies developed for the rapid evolution of activities linked to new designs, new products, and new manufacturing processes and systems. Innovative Japanese carmakers have stimulated international performance comparisons in these activities. International technology alliances may be one way of gaining access to new competitive technologies. Risks and costs associated with new product development can be shared among the partners and more effective use can be made of manufacturing facilities and production capabilities. Sometimes, an alliance agreement may lead to the deployment of new capabilities. However, in spite of this potential, the literature presents the success rate of alliances at less than 50%. Our study considers two examples of companies that developed international joint ventures (IJVs): Rover with Honda, and Seat with Volkswagen. Since these two European peripheral companies, Rover and Seat, no longer remain as independent firms, we are interested in identifying the reasons leading to the success or failure of these IJVs as regards the New Product Development (NPD) process. In particular, in both cases the paper looks at the problems of the weaker partner becoming increasingly dependent on the other partner and the need for a well-defined strategy to benefit from IJVs.  相似文献

This paper aims to identify which personal features of customers may determine their likelihood to join a grocery retail loyalty program. We consider five aspects: price sensitivity, search for variety, shopping enjoyment, attitude toward loyalty schemes, and one personality trait: privacy concerns. Some of these variables have already been explored in the literature. Where our research breaks new ground is in establishing the difference between profiles of customers attracted by two of the most common types of loyalty programs currently used by grocery retail firms: a reward program and a loyalty card. The two kinds of program evidence differences in how they are managed, and we posit that the drivers of likelihood to take part in each are different. The study was carried out using logistic regression with a sample of 600 clients of a Spanish supermarket chain. Findings show that one particular type of customer is more likely to take part in these schemes: those displaying little shopping enjoyment, who are greatly concerned with privacy, and who show a favorable attitude toward loyalty programs in general. Furthermore, as expected, differences were observed between drivers of participation likelihood in reward programs and loyalty cards.  相似文献

We examine how the interaction between education and corruption affects institutional reform and economic development. While corruption reduces average income and education, education increases not only output and hence potential corruption rents, but also produces more informed electorates that better monitor government actions. We find that economies with intermediate levels of education remain in a poverty trap since the level of skills creates sufficient corruption rents but not enough monitoring. Economies with low or high levels of education can escape the poverty trap, and inequality plays a key role in determining whether this occurs through a change in institutions or an expansion of education.  相似文献

This paper provides evidence that audit reports convey relevant evidence for inferring the existence of underlying, unrevealed, financial imbalances. Unlike previous works, which studied US listed-firms bankruptcy, our research deals with Spanish non-financial SMEs under financial stress. Our results indicate that the audit of distressed SMEs has several distinctive features: higher auditor rotation, more qualified reports, and non-compliance with deadlines to approve and file the annual financial statements. We use this evidence to build and test a parsimonious and reliable forecast model. Several implications for auditors’ independence, information quality, and failure forecast are discussed.  相似文献
