The purpose of this paper is twofold: first, to propose a new robust volatility ratio (RVR) that compares the intraday high–low volatility with that of the intraday open–close volatility estimator; and second, to empirically test the proposed RVR on the cross-sectional (CS) average of the constituent stocks of India’s BSE Sensex and US’s Dow Jones Industrial Average index to find the evidence of “excess volatility.”

The authors model the proposed RVR by assuming the logarithm of the price process to follow the Brownian motion. The authors have theoretically shown that the RVR is unbiased in the case of zero drift parameter. Moreover, the RVR is found to be an even function of the non-zero drift parameter.

The empirical results show that the analysis based on the RVR supports the existence of “excess volatility” in the CS average of the constituent stocks of India’s BSE Sensex and US’s Dow Jones index. In particular, the authors have observed that the CS average of individual constituent stocks of BSE Sensex is found to be more excessively volatile than the US’s Dow Jones index during the period of the study from January 2008 to September 2016, based on multiple k-day time window analysis.

The study has implications for the policy makers and practitioners who would like to understand the volatility behavior in the asset returns based on the RVR of this study. In general, the proposed model can be used as a specification tool to find whether the stock prices follow the random walk behavior or excessively volatile.

The authors contribute to the existing volatility literature in finance by proposing a new RVR based on extreme values of asset prices and absolute returns. The authors implement the bootstrap technique on RVR to find the estimates of mean and standard error for multiple k-day time windows. The RVR can capture the excess volatility by comparing two independent volatility estimators. This is possibly the first study to find the CS average of all the constituent stocks of BSE Sensex based on the RVR.

This study uses an eye-tracking device to examine the effects of dissenting opinion on information search style and decision quality, using insights from dual-process theory. When evaluating strategic outcomes, managers not exposed to a dissenting opinion employ directed information search using System 1 (heuristic, automatic cognitive processing), leading to low-quality decisions. Providing a dissenting opinion causes managers to use System 2 (sequential information search characterized by deliberate, slow, and effortful cognitive processing), leading to higher-quality decisions. This study provides useful insights into the cognitive processes underlying managers' judgments, and the factors that influence their decisions. We conclude by discussing the critical role of dissent in business practices, and explain how dissent affects people's System 2 cognitive processes.

This chapter aims to identify the impact of misbelief and heuristics on the engagement of giggers and customers with gigging organisations. This is of value due to the plethora of gigging opportunities and our lack of knowledge about how and why people choose to take up these opportunities. In addition, the gigs may frequently go unrecorded with payments made through systems such as PayPal which can allow international payments to be made without remittances. This chapter utilises some of the primary evolutionary theories to explore the efficacy and conflict in communications between gigging organisations, their customers and providers (giggers). Those selected are: misbelief in the conscious mind; and heuristics, such as the availability and confirmatory heuristics in the unconscious mind. Misbelief is addressed as a spandrel, and heuristics are discussed through the lens of fast and frugal approaches. Through a text analysis of 77 international gigging organisations, the messages conveyed are assessed against both evolutionary theory and prior research into the gig economy. The findings are that evolutionary psychology provides a useful framework for analysing these messages, as well as aiding understanding of gigging behaviours. HRM practitioners could make use of this form of analysis to support their design of interactions with giggers to ensure clarity on both sides.

Government policy mandates information disclosure in financial communications to protect consumer welfare. Unfortunately, low readability can hamper information disclosures’ meaningful benefits to financial decision making. Thus, this experiment tests the product evaluation and decision satisfaction of Korean consumers with less or more subjective knowledge and with or without personal finance education.

A between-subjects experiment examined responses of a nationally representative sample of 400 Korean consumers toward a Korean-language credit card advertisement.

Financial knowledge improves financial product evaluation and decision satisfaction. More readable disclosures improved evaluation and satisfaction among less knowledgeable consumers. Less readable disclosures did not. Consumers without financial education exhibited lower evaluations and decision satisfaction regardless of readability. More knowledgeable consumers and those with financial education performed equally well regardless of disclosure readability.

Financial service providers seeking more accurate evaluations and better decision satisfaction among their customers should use easier-to-read disclosures when targeting consumers with less prior financial knowledge.

One-size-fits-all financial communications are unlikely to achieve public policy or consumer well-being goals. Government-mandated information should be complemented by augmenting financial knowledge and providing personal finance training.

Although almost a quarter of the world’s population lives in East Asia, this is the first examination of readability in disclosures written in East Asian characters rather than a Western alphabet. Previous readability research on Asian-originating financial disclosures has been conducted on English-language texts. This study extends knowledge of readability effects to growing East Asian markets.

Purpose – Extensive research in the area of consumer behavior has documented the “Country of Origin Effect,” which identifies country of origin as an important decision variable in evaluating products and services. Past research has mostly assumed that country of origin effect is driven by the performance of the products originating in that country. However, consumers can also form opinions about countries based on exposure to information that is unrelated to the product and may have roots in macro factors such as history, culture, and politics. These emotions, while extraneous to the product, can also influence product evaluations along with performance-related country information.Design/methodology/approach – This review examines research addressing both performance and emotional perceptions related to country of origin.Findings – This review presents an integrating framework termed “Nation Equity” to systematically understand and examine the influence of various dimensions of country of origin on consumer decision making.

This paper aims to propose a framework based on the unbiased extreme value volatility estimator (namely, the AddRS estimator) to compute and predict the long position and the short position value-at-risk (VaR) and stressed expected shortfall (ES). The precise prediction of VaR and ES measures has important implications toward financial institutions, fund managers, portfolio managers, regulators and business practitioners.

The proposed framework is based on the Giot and Laurent (2004) approach and incorporates characteristics like long memory, fat tails and skewness. The authors evaluate its VaR and ES forecasting performance using various backtesting approaches for both long and short positions on four global indices (S&P 500, CAC 40, Indice BOVESPA [IBOVESPA] and S&P CNX Nifty) and compare the results with that of various alternative models.

The findings indicate that the proposed framework outperforms the alternative models in predicting the long and the short position VaR and stressed ES. The findings also indicate that the VaR forecasts based on the proposed framework provide the least total loss for various long and short position VaR, and this supports the superior properties of the proposed framework in forecasting VaR more accurately.

The study contributes by providing a framework to predict more accurate VaR and stressed ES measures based on the unbiased extreme value volatility estimator.

This study is set out to assess the country of origin effect on Turkish consumption practices in order to provide a richer context for its formation process.

The research is exploratory and interpretative in nature. It follows a qualitative design with in-depth analysis of consumption experiences by utilizing semi-structured interviews.

The research shows that country of origin effect is product specific, and when it exists, it has an essential effect on product evaluations. It reveals that the country of origin effect is intrinsically constituted with the individual perceptions of and attitudes toward brands, countries, and past experiences, and it is extrinsically constituted with socially created perceptions by media, marketplace myths, and popularity.

This research investigated country of origin effect in a specific context of a developing country with a qualitative methodology. Unlike the existing literature, this study analyzes consumers’ actual purchase decisions in different product categories. Country of origin effect is found to be formed by individual and societal factors.

Although microblogs have become an important information source, the credibility of their postings is still a critical concern due to the open and unregulated nature. To understand the antecedents of microblog information credibility, the purpose of this paper is to investigate the dual-role of cognitive heuristics (i.e. the additivity and bias roles) and the effect of gender differences.

This study collected data via an online field survey of active microblog users, and a total of 204 valid responses was received.

This study demonstrates the dual-role of source credibility and vividness, the additivity role of microblog platform credibility, and the bias role of social endorsement. Furthermore, this study also found out gender difference that the additivity role of cognitive heuristics was stronger for men while bias role was stronger for women.

This research enriches the microblog literature by examining the cognitive heuristic determinants as key predictors of microblog information credibility, and contributes to the information credibility literature by identifying and analyzing the dual-role effect of cognitive heuristics and corresponding gender differences.

This study can help organizations better manage their reputation, especially during the reputation crises, and also serves as a reminder to microblog platform operators of the importance of their microblog platform credibility.

This study investigates the dual-role effect of cognitive heuristics (i.e. the additivity role and bias role) and corresponding gender differences that are less touched on before, and thus provides a more nuanced understanding of the more complex effects of cognitive heuristics.

The purpose of this paper is to explore country‐of‐origin (COO) effects on service evaluation in an emerging market.

To gain insight, 24 in‐depth interviews were conducted with stakeholders in five West African countries. A conjoint analysis was also conducted to further explore COO effects.

Propositions were developed based on findings from the qualitative study and conjoint analysis. Situational personal characteristics, such as motivation and ability to process information, may influence use of COO attributes in evaluating a service. Individual characteristics, such as ethnocentrism and culture orientation, may influence COO preference in service evaluation.

Propositions and findings will assist firms considering entering a market in terms of service offerings and positioning strategies.

While COO and consumer products have been widely studied in the literature, mostly within the contexts of industrialized nations, the paper examines COO effects with a service within the context of an emerging market.

A large body of research has analyzed individual psychological characteristics as antecedents of strategic decision-making. However, this research has mainly focused on trait-based characteristics that explain impaired strategic decision outcomes. Recently, PsyCap has been proposed as an alternative driver of strategic decision outcomes that, in contrast to other drivers, can be influenced by management.

Drawing on research on psychological capital (PsyCap), a psychological construct conceptualized as a state-like individual strength that is malleable, the authors argue that PsyCap exerts an inverted curvilinear effect on strategic decision outcomes. The authors use a computerized strategic decision simulation involving 102 managers to empirically test our hypotheses.

The authors show that PsyCap improves strategic decision outcomes up to an inflection point, after which it negatively affects those outcomes. The authors also show that this effect is mediated by heuristic information processing.

For the empirical study the authors relied on a sample of 102 practicing managers from the financial services industry in Germany.

PsyCap has been shown to be malleable through, for instance, micro-interventions and dedicated web-based trainings. Therefore, depending on managers' PsyCap levels, either further increases in PsyCap or a regulation of this characteristic might be appropriate in order to optimize strategic decision outcomes.

As a state-like individual strength that is malleable, PsyCap might serve as a management characteristic that is particularly important in challenging situations such as the COVID-19 pandemic.

This paper contributes to research on strategic decision making by introducing PsyCap as an important antecedent of strategic decision outcomes that – in contrast to other individual characteristics – is state-like and, hence, malleable.
