A trade restrictiveness index (TRI) aggregates an entire protection structure into a single uniform measure that is consistent with trade theory and reflects the extent of policy interventions on trade or welfare. Although there are several variants of a TRI, all approaches aggregate protective measures using weights that depend on import demand and export supply elasticities; some studies ignore cross-price effects while others account for them. This study measures the degree of bias introduced by ignoring cross effects. It provides a practical approach to account for demand- and supply-side cross-price effects in a multi-commodity TRI setting. This approach is illustrated with a case study of distortions in the Canadian crop and livestock sector. Domestic demand and supply cross effects are approximated using a “constant differences of elasticities of substitution” functional form. On average, over the period 1996–2016, we find that cross-price effects do make a difference, and that including them makes the TRI 27% higher than an approach which ignores them. Furthermore, both TRI approaches produce indices that are higher and more variable than the OECD's percentage Producer Support Estimate (PSE) that measures policy transfers as a share of gross farm receipts. The fundamental differences between a TRI and PSE% is driven by market price support for milk.  相似文献

This paper considers the identification of social interaction effects in the context of multivariate choices. First, we generalize the theoretical social interaction model to allow individuals to make interdependent choices in different activities. Based on the theoretical model, we propose a simultaneous equation network model and discuss the identification of social interaction effects in the econometric model. We also provide an empirical example to show the empirical salience of this model. Using the Add Health data, we find that a student's academic performance is not only affected by academic performance of his peers but also affected by screen‐related activities of his peers.  相似文献

We study pricing strategies of competing firms selling heterogeneous products to consumers. Goods are substitutes and there are network externalities between neighboring consumers. In equilibrium, firms price discriminate based on the network positions and charge lower prices to more central consumers. We also show that, under some conditions, firms' equilibrium profits decrease when either the network becomes denser or network effects increase. In contrast, consumers always benefit from being more connected to each other. We determine the optimal network structure and compare uniform pricing and discriminatory pricing from the perspectives of firms and consumers.  相似文献

Philanthropic foundations are the object of little research in Canada and Quebec. Our article recognizes the role of these organizations, as well as the presence of powerful new foundations, rich in assets and donations. This article consists of three parts. The first part presents a theoretical review of the American literature published from 2000 on. The second part examines data that we extracted from three main repertoires. Though informative, these repertoires tend to classify Canadian and Quebec foundations in categories that are mostly fiscal and legal and tend to break them down as public or private foundations. We therefore question the limits of studies based on such categories. In the third part of the article we propose a theoretical framework based on a sociopolitical point of view in an attempt to transcend the binary approach. Our approach borrows from the concepts of social and solidarity economy (SSE) and plural economy in order to better understand the new institutional arrangements in which foundations operate. This theoretical framework allows us to analyse foundations as actors of the SSE even though they might not reproduce automatically the principles and the values of the SSE in their behaviours. On the contrary, from the standpoint of a plural economy we may be in a better position to develop a sound sociopolitical analysis of diverse configurations and hybrid forms resulting from emulations or transactions between the principles of the social and solidarity economy (reciprocity), the private economy (competition) and the public economy (redistribution).  相似文献

Evidence suggests that society still does not view whistleblowers as wholly legitimate—despite legal protections now offered in some jurisdictions, such as the United States. Drawing on a discourse analysis (i.e., an examination of statements), we investigate the well‐publicized stories of seven whistleblowers from 69 sources, including books, first‐ and second‐hand interviews, websites, and videos. Our focus is to examine how whistleblower discourses can build legitimacy by more tightly defining the whistleblower role and demonstrating its alignment with social norms. Using whistleblower self‐narratives, we identify four narrative patterns: (i) Trigger(s)—the event(s) leading to whistleblowing; (ii) Personality traits—whistleblower's morality, resourcefulness, and determination; (iii) Constraints—barriers requiring regulatory and organizational change; and (iv) Consequences—the longer term positive impact of the whistleblowing act. These patterns rely on symbolic, analogical, and metaphorical framing to allow others to better understand the role of whistleblowers and enlist their support. Exploring a data set of 1,621 press articles, we find indications that these narrative patterns resonate in the media—which provide a form of support and may be instrumental in legitimizing the whistleblower role. Grounded on these results, we develop a legitimacy construction model of the whistleblower role, that is, a representation of how role legitimacy is produced and sustained. From this model, we identify a number of important areas for future research.  相似文献

This is an expository paper on applications of statistics in the field of general insurance, also called non‐life insurance. Unlike life insurance where advanced statistical techniques have long been part of financial mathematics and actuarial applications, their use is only relatively recent in non‐life insurance. The business model of insurance companies, especially those active in non‐life insurance, has seen dramatic changes over the last 15 years. The aim of this paper is to convince the readers that especially today non‐life insurance is not only an exciting ground to apply existing modern statistical tools but also a fertile environment for new and challenging statistical developments. The activities of an insurance company can be viewed as an industrial process where data management and data analysis play a key role. That is why a fundamental understanding of data‐related issues (such as data quality, variability, analysis and correct interpretation) is so essential to the insurance business. These are exactly the tasks where professional statisticians excel. Also, a better understanding of the field of general insurance by statisticians will promote fruitful exchanges between actuaries and statisticians, thereby helping to bring actuarial and statistical professional societies closer to each other. Selected examples are used to cover the essential aspects of general insurance, and all of them are based on the author's experience. The paper concludes with some remarks on the role of statisticians working in general insurance.  相似文献

This paper examines the processes by which individuals work their sense of organizational and professional identity in the aftermath of a professional failure. Drawing on twenty-five interviews carried out with former members of Arthur Andersen who mostly worked for the firm in Canada and the United Kingdom, we investigate interviewees’ identity work ensuing from the breakdown of the firm. Specifically, identity work comprises processes by which individuals reflectively seek to maintain or revise their sense of identification with the AA organization and also with the public accounting profession, along with developing self-understandings regarding causes and consequences ensuing from the firm’s collapse. Our analysis indicates that four interpretive schemes or patterns mainly characterize interviewees’ identity work: disillusion; resentfulness; rationalization; and hopefulness. Each of these patterns can be viewed as conveying a distinct representation of what “truly” happened within AA. In this sense, identity work, sense-making and truth contests are inextricably linked altogether. Moreover, the present paper underlines the pertinence of studying entangled processes of identity work and sense-making in order to better understand how broader social forces or discourses (e.g., commercialization and risk) are experienced and translated by the self in the context of identity-threatening events. That is, the identity work/sense-making nexus constitutes a relevant theoretical anchoring to study the circulation of discourses in society.  相似文献

We present a simple model where mergers benefit consumers, harm outsiders and, depending on the shape of demand, can be profitable for insiders (and where mergers do not involve cost synergies).  相似文献
