Multi-party computation mechanism for anonymous equity block trading: A secure implementation of turquoise plato uncross

Dark pools are financial trading venues where orders are entered and matched in secret so that no order information is leaked. By preventing information leakage, dark pools offer the opportunity for large volume block traders to avoid the costly effects of market impact. However, dark pool operators have been known to abuse their privileged access to order information. To address this issue, we introduce a provably secure multi-party computation mechanism that prevents an operator from accessing and misusing order information. Specifically, we implement a secure emulation of Turquoise Plato Uncross, Europe's largest dark pool trading mechanism, and demonstrate that it can handle real world trading throughput, with guaranteed information integrity.     

When the going gets tough: the influence of expatriate resilience and perceived organizational inclusion climate on work adjustment and turnover intentions

Abstract

Despite the strong evidence for the beneficial influence of resilience for employee stress resistance in domestic settings, the construct has not received much attention in the expatriation literature, where stress is considered a major factor for expatriates’ poor cross-cultural adjustment and turnover. Drawing upon conservation of resources theory, the present study examines resilience as an antecedent of expatriate work adjustment and turnover intentions. Furthermore, this study investigates the moderating role of perceived organizational inclusion climate as a resource-protecting organizational factor. Results from a survey of 175 expatriates in South Korea indicate that resilience is positively related to expatriate work adjustment and that these positive effects are more pronounced when expatriates perceive their organizational climate to be highly inclusive. Furthermore, findings suggest that work adjustment mediates the effects of resilience on turnover intentions and that this mediation is moderated by a perceived organizational inclusion climate. Implications for theory and practice are discussed.     

A comparison of the dominant meta programme patterns in accounting undergraduate students and accounting lecturers at a UK business school

Meta programmes are a means of describing the behavioural traits that a person exhibits when interacting with other people. An understanding of meta programmes can improve communication between individuals and this may have implications for teaching. The purposes of this study are first to identify the dominant meta programme patterns of first year accounting undergraduates at a UK business school. An earlier pilot study validated use of the Motivation Profile Questionnaire (MPQ) to elicit the dominant meta programmes of accounting lecturers at the same Business School (Brown, 2002). Secondly, the students' meta programmes are compared with those of their accounting teachers to identify whether there are any differences or similarities between the two groups. The matching of the meta programmes of the teachers and students would enhance communication whilst major differences in meta programmes would make communication more difficult. A sample of 62 first year accounting undergraduates and 20 accountancy teachers completed the MPQ. The results indicate that, on average, the accounting students have similar dominant meta programme patterns to their accounting teachers. The implications of the findings for improving communication and therefore teaching are discussed, along with the scope for further research.     

Gendering and Gender in Public Service Organizations: Changing Professional Identities Under New Public Management

This article examines the enactment of new public management (NPM) in public service professional organizations, the nature of professional/managerial subjectivities promoted within the NPM discourse, and the implications for male and female professionals/managers. The article has two aims. First, taking a gender ing organization perspective, it explores the gendered meanings of NPM and the promotion of new professional/managerial subjectivities. Second, focusing on gender in organizations, the article then considers the implications of the enactment of NPM for male and female professionals/managers. The article illustrates the complex, manifold and fluid nature of both the meanings ascribed to NPM and individual responses. It is argued that a gender lens offers a more nuanced and sophisticated understanding of NPM enactment and the implications of this for public service professionals/managers are considered.     

The Evolution of Marks and Spencer

Financial data drawn from Marks and Spencer's archives and annual reports is used to identify five phases in the Company' sales growth. Early, rather erratic, growth, often through acquisition, gave way to a second phase of store development funded by the Company's floatation in the 1920s. Sales growth in the third phase came substanriveljl through an increase in store size. A fourth phase involved irnprovernerzts in labour and space productivity. The final and current phase of evolution emphasises divers(fication. The pattern of evolution is compared with two theories of retail change, the Wheel of Retailing and the Retail Accordion. Neither is compatible with the sustained growth exhibited, indeed both theories could be said to predict the failure of the Company's overall strategy.     

Firm Heterogeneity and Export Pricing in India

We examine export pricing by Indian manufacturing firms in the early 2000s using a unique data set that matches firm characteristics with product and destination‐level trade data. We find that, in contrast to China and other countries, firm productivity is negatively associated with export prices, and export prices are negatively associated with distance while positively associated with remoteness. Our conjecture is that Indian innovation costs, which are higher than China's, drive down the scope for quality differentiation causing a negative association between productivity and prices. To the best of our knowledge, this is the first empirical evidence consistent with heterogenous goods and short quality ladders, a theoretical possibility noted in the study by Antoniades (2012), an outcome that arises here because of domestic Indian economic and regulatory features.     

Strategic tariffs, tariff jumping, and heterogeneous firms

The majority of research to date investigating strategic tariffs in the presence of multinationals finds a knife-edge result where, in equilibrium, all foreign firms are either multinationals or exporters. Utilizing a model of heterogeneous firms, we find equilibria in which both pure exporters and multinationals coexist. We utilize this model to study the case of endogenously chosen tariffs. As is standard, Nash equilibrium tariffs are higher than the socially optimal tariffs. Unlike existing models with homogeneous firms, we find that non-cooperative tariffs promote the existence of low-productivity firms relative to the socially optimal tariffs. This highlights a new source of inefficiency from tariff competition not found in models of homogeneous firms. In addition, we find that in many cases the Nash equilibrium tariff when FDI is a potential firm structure is lower than when it is not. As a result, FDI improves welfare by mitigating tariff competition.     

A review of empirical research on interorganizational relations in tourism

During the last few decades, a growing body of literature has been produced on various aspects of interorganizational relations (IOR) in tourism. This paper provides a review of that literature. The findings are based on a review of 269 empirical papers published in 37 tourism journals between 1989 and the first quarter of 2017. The review identifies six main research themes relating to relationship formation, structure and activities, governance, maintenance, outcomes, and evolution. Based on the insights from this review, an organizing framework for research on IOR in tourism is developed and four opportunities for advancing research on IOR in tourism are proposed relating to the pursuit of causal inference, supply networks as a unit of analysis, quantifying outcomes of IOR in tourism, and addressing marginalized topics.     

Did the Federal Crop Insurance Reform Act Alter Farm Enterprise Diversification?

We estimate how much United States farms changed enterprise diversification in response to a marked increase in crop insurance coverage brought about by the 1994 Federal Crop Insurance Reform Act, which substantially increased insurance subsidies. The analysis exploits farm‐level panel census data to compare farm‐specific changes in enterprise diversification over time. By examining diversification decisions of the same farms over time, we control for time‐invariant unobserved individual heterogeneity. We then use pooled cross‐sectional data from the United States Department of Agriculture (USDA) Agricultural Resource Management Survey to estimate the relationship between farm diversification and average returns. We find that the insurance subsidies caused a modest increase in enterprise specialisation and production efficiency. Estimated efficiency gains are far less than the subsidies.
