A new approach to bad news effects on volatility: the multiple-sign-volume sensitive regime EGARCH model (MSV-EGARCH)

In this paper, using daily data for six major international stock market indexes and a modified EGARCH specification, the links between stock market returns, volatility and trading volume are investigated in a new nonlinear conditional variance framework with multiple regimes and volume effects. Volatility forecast comparisons, using the Harvey-Newbold test for multiple forecasts encompassing, seem to demonstrate that the MSV-EGARCH complex threshold structure is able to correctly fit GARCH-type dynamics of the series under study and dominates competing standard asymmetric models in several of the considered stock indexes.

Prudent expectations equilibrium in economies with uncertain delivery

In an economy with private information, we introduce the notion of objects of choice as lists of bundles out of which the market selects one for delivery. This leads to an extension of the model of Arrow–Debreu that is used to study trade ex ante with private state verification. Under the assumption that agents are prudent, equilibrium is characterized by the fact that agents consume bundles with the same utility in states that they do not distinguish. This is a weaker condition than the restriction of equal consumption imposed by Radner (Econometrica 36(1), 31–58, 1968), therefore, some no trade situations are avoided and the efficiency of trade increases.     

Malmquist indices of productivity change in Portuguese banking: The deregulation period

This paper will evaluate productivity change in Portuguese banking using the Malmquist productivity index. The results show that between 1990 and 1997, banks in Portugal witnessed increased productivity and strong technological progress. Both small and large banks experienced higher productivity and technological change scores, while mid-sized institutions are putting more effort into catching-up policies. Rural banks have experienced strong productivity growth and are catching up with the best practices but lower levels of technological change. Urban banks show higher productivity growth and technological change levels. Government-owned banks have experienced lower levels of productivity change. Finally, the asset per employee ratio shows a positive correlation with the productivity scores, suggesting that this simple index is a good proxy for productivity.     

Technology infusion in service encounters

Service encounters are critical in all industries, including those that have not been traditionally defined as service industries. The increasing deployment of technology is altering the essence of service encounters formerly anchored in a “low-tech, high-touch” paradigm. This article explores the changing nature of service, with an emphasis on how encounters can be improved through the effective use of technology. The authors examine the ability of technology to effectively (1) customize service offerings, (2) recover from service failure, and (3) spontaneously delight customers. The infusion of technology is examined as an enabler of both employees and customers in efforts to achieve these three goals. Although the infusion of technology can lead to negative outcomes and may not be embraced by all customers, the focus of this article is on the benefits of thoughtfully managed and effectively implemented technology applications. Past research and industry examples are featured and future research directions and managerial implications are highlighted.

A note reconsidering a post-Keynesian model of growth and distribution in the globalization context

We treat an extension of the Metcalfe and Steedman model of growth and distribution in a small open economy with government activity. We show, simultaneously, that certain kinds of taxation and government expenditures will not affect the essential nature of the “Cambridge Equation.” This is important due to the increasing process of Financial Globalization which can be responsible for changing the profit distribution between capitalists and workers. The present note aims at integrating the public sector and the foreign trade together into the model, based on previous literature that, with few exceptions, treats them separately. To do so, a new framework is proposed. Our contribution shows that workers’ income grows when the Current Account in the balance of payments is in surplus, a result not studied by Teixeira and Araújo. The discussion includes recent literature concerning with limits of applicability of such analytical model, dealing with more realistic economies including the process of globalization.     

Speculative pressure

The paper investigates the information content of speculative pressure across futures classes. Long-short portfolios of futures contracts sorted by speculative pressure capture a significant premium in commodity, currency, and equity markets but not in fixed income markets. Exposure to commodity, currency, and equity index futures’ speculative pressure is priced in the broad cross-section after controlling for momentum, carry, global liquidity, and volatility risks. The findings are confirmed by robustness tests using alternative speculative pressure signals, portfolio construction techniques, and subperiods interalia. We argue that there is an efficient hedgers-speculators risk transfer in commodity, currency, and equity index futures markets.     

Advertising in streaming video: An integrative literature review and research agenda

Streaming video (SV), such as YouTube, is a new media widely used nowadays. Nevertheless, there is a lack of knowledge about advertising in SV. In view of this, through a search in the rich depository of the Scopus database, this article presents the first integrative literature review about advertising in SV. Searching every article and conference paper related to the topic published until May 04, 2020, 59 studies were found and classified into two main topics: marketing studies (35), mostly focused on evaluating or exploring advertising in SV, and computational studies (24), focusing on the development of systems for the insertion of ads into SV. All knowledge present in these studies was summarized so that readers (both scholars and practitioners) could have easy access to the main contributions and information present in each study. Moreover, future research directions in six main themes are presented through a research agenda.     

Built environment analysis for road traffic hotspot locations in Moshi,Tanzania

Road traffic injuries (RTIs) cause significant morbidity and mortality in low- and middle-income countries. Investigation of high risk areas for RTIs is needed to guide improvements. This study provides built environmental analysis of road traffic crash hotspots within Moshi, Tanzania. Spatial analysis of police data identified 36 hotspots. Qualitative comparative analysis revealed 40% of crash sites were on local roads without night lighting and increased motorcycle density. Paved narrow roads represented 26% of hotspots and 13% were unpaved roads with uneven roadsides. Roadside unevenness was more predominate in low risk [n = 19, (90.5%)] than high risk sites [n = 7 (46.7%)]. Both low [n = 6 (28.6%)] and high risk [n = 1 (6.7%)] sites had minimal signage. All sites had informal pedestrian pathways. Little variability between risk sites suggests hazardous conditions are widespread. Findings suggest improvement in municipal infrastructure, signage and enforcement is needed to reduce RTI burden.     

Fostering mutual gains: Explaining the influence of high‐performance work systems and leadership on psychological health and service performance

Despite the growing importance of sustainable management of human resources, human resource management and leadership research on mutuality in the employment relationship has proceeded in a parallel fashion. Drawing on self‐determination theory, this study proposes an integrative model of human growth by addressing two interrelated questions: (a) how and why experienced service‐oriented high‐performance work systems (HPWS) and unit service leadership relate to psychological health and service performance and (b) whether thriving at work and psychological health serially mediate the relationships between the two contextual antecedents and service performance. Our findings revealed that experienced service‐oriented HPWS and unit service leadership related to service performance but indirectly through thriving at work. However, experienced service‐oriented HPWS but not unit service leadership related to psychological health through thriving at work. Furthermore, thriving at work and psychological health serially mediated the relationship between experienced service‐oriented HPWS (but not unit service leadership) and service performance.
