Stock prices and the efficient market hypothesis: Evidence from a panel stationary test with structural breaks

This paper investigates whether the efficient market hypothesis holds in stock markets under different economic development levels over the period January 1999 to May 2007. We employ a state-of-the-art panel data stationarity test which incorporates multiple structural breaks. Evidence indicates that when accommodating general forms of cross-sectional dependence as well as controlling for finite-sample bias, the real stock price series appear to be stationary in 32 developed and 26 developing countries, respectively, which is in sharp contrast to the findings in the existing literature. Thus, real stock price indices are stationary processes that are inconsistent with the efficient market hypothesis. This shows the presence of profitable arbitrage opportunities among stock markets. According to these estimated structural breakpoints, we are also able to discover the reason for why there has been a huge impact from past stock prices.     

TESTING FOR STATIONARITY OF INFLATION RATES WITH COVARIATES

This paper distinguishes between the stationarity and nonstationarity of inflation in 18 OECD countries through several unit root tests with covariates. These covariate tests are more powerful than the conventional ones through correlated covariates. Both unit root and stationarity null hypotheses are tested in this study. Our empirical results indicate that the efficient univariate unit root tests fail to reject the unit‐root hypothesis for 15 countries, whereas the covariate tests provide strong evidence in support of mean reversion in inflation for almost all countries. Overall, the findings unveil new evidence in favor of stationarity in international inflation. Policy implications on the empirical results are provided as well.     

Models of care in outpatient cancer centers

While rapid changes in the treatment of cancer have been driven by research-based evidence, innovations in cancer care delivery have lagged behind that seen in cancer treatment. A literature review and ten semi-structured interviews were conducted to identify models of care in the ambulatory oncology setting to be adopted by a comprehensive cancer center. Four models were identified from the literature review but none were widely recognized or adopted by administrators. Findings suggested some common themes that should be included in an optimal model of care. These themes are in support of the burgeoning efforts seen in the promotion of interprofessional education and practice for quality improvement. Unique challenges related to the contextual factors in the ambulatory oncology settings suggest quality improvement interventions should be tailored to meet the specific needs of the care facility and its workforce.     

What holds back high-growth firms? Evidence from UK SMEs

High-growth firms are seen as vital for economic growth. It is important for policy and theory to consider the barriers faced by firms achieving high growth and those with the potential to do so. This article uses data for 4,858 UK SMEs to investigate the obstacles perceived by two sets of firms: (1) firms in periods of high growth and (2) potential high-growth firms, which are observationally similar but are not achieving high growth. The results suggest high-growth firms perceive problems in six areas: recruitment, skill shortages, obtaining finance, cash flow, management skills and finding suitable premises. Potential high-growth firms feel held back by the economy, obtaining finance, cash flow and their management skills, but are less likely to perceive regulation is a problem. The results have implications for theory on high-growth firms and policies focussed at them.     

Mood management through metaverse enhancing life satisfaction

This study aims to explore a social metaverse's positive effects as mood management on consumers' life satisfaction and usage intentions. A total of 304 survey responses from active users of a popular social metaverse platform, Zepeto, were collected with help from an online survey firm. Structural equation modeling analysis was conducted using AMOS 25.0. The direct paths from social metaverse consumption as positive mood enhancement and negative mood alleviation to consumers' life satisfaction were significant, which led to greater usage intentions. Positive mood enhancement influenced usage intentions both directly and indirectly through increased life satisfaction; however, the effect of negative mood alleviation on usage intentions was fully mediated by life satisfaction. Interestingly, for the players who spend money in the social metaverse, only the path from negative mood alleviation to usage intentions mediated by life satisfaction was significant.     

Servitization of Global Manufacturing Business

This study examines important but understudied issues in the servitization of global manufacturing firms. We begin with a review of the literature that suggests that global manufacturing firms can grow by integrating services into traditional products in a rapidly changing business environment. We fill a gap in the literature by considering exogenous (i.e., country-level and industry-level) and endogenous (i.e., firm-level) antecedents of servitization. We posit that home-country institutional development has a positive effect on global manufacturing firms’ servitization. We also posit that a high level of industry competition is favorably associated with servitization and that a firm’s technological capability and geographic diversification are related to servitization. To test these arguments, we made a comprehensive data set by using the Thomson Reuters database, which provides the financial information of 301 global manufacturing firms in the 2015 Forbes Global 1,000, and by using annual reports published on the websites of the firms.

Anti-consumption beyond boundaries: From niche topic to global phenomena

The first anti-consumption special issue was published by Psychology & Marketing in 2002. More than a decade later, in 2018, the International Center for Anti-consumption Research held its seventh Symposium at the University of Almeria, Spain. This gathering was accompanied by an open call-for-papers in Psychology & Marketing to create a much-anticipated follow-up special issue. Many papers were received for both the symposium and official call. This editorial introduces the final 10 papers that comprise the Psychology & Marketing 2020 special issue on anti-consumption. While the area of anti-consumption has mushroomed into a vast array of work since 2002, this editorial provides four major themes that help to frame the contributions of the 10 new papers as well as set the scene for future work in anti-consumption. The four themes are: Conceptual clarity and refinement; ideological perspectives; environmental and sustainability focus; and novel outlooks on anti-consumption.
