Abstract

Purpose

This study’s goal was to identify how several markets have developed over time and what determinants have influenced this process, based on adaptive markets hypothesis (AMH). In this regard, the authors consider that agents are driven by the seeking for abnormal returns to stay “alive” and their environment could somehow modify their decision-making processes, as well as influence the degree of efficiency of the market.

Design/methodology/approach

The authors collected the daily closing-of-the-market index from 50 countries, between 1990 and 2022. The sample includes emerging countries, developed countries and frontier markets. Then, the authors ran multilevel modeling using Hurst exponent as an informational efficiency metric estimated by two different moving windows: 500 and 1,250 observations (approximately 2 and 5 years).

Findings

The results indicate that the efficiency of the markets is not constant over time. The authors also have identified that markets follow a cyclical pattern of efficiency/inefficiency, and they are currently in a period of convergence to efficiency, possibly explained by the increase in computational capacity and speed of the available information to agents. In addition, this study identified that country characteristics are associated with market efficiency, considering institutional factors.

Originality/value

Studies of this nature contribute to the literature, considering the importance of better comprehension of market efficiency dynamics and their determinants, specially observing other theories on the relationship between information and markets (like AMH), which work with other investor assumptions than those used by efficient market hypothesis.

Abstract

Ethical principles and practices frequently support the position that people with disability are vulnerable. Vulnerability in research traditionally infers a need for protection from harm and raises questions over the person’s capacity to consent and engage. In addition, vulnerability in ethics infers a state of permanency and one that is all-encompassing for everyone within the vulnerable groups. This construction of vulnerability in effect legitimises the exclusion of people with disability from research or monitors and restricts how people with disability can engage in research. This results in an implicitly ableist environment for research. In this chapter, which has been led by researchers with disability, we argue that there is a critical need to move beyond a popularised social construction of vulnerability which serves to perpetuate barriers to including people with disability in research. Like all terms, the traditional and popular construction of vulnerability is open to reclaiming and reframing. Under this reconstruction, what is traditionally viewed as a limiting vulnerability can be owned, openly disclosed and accommodated. Following a pandemic-inspired ‘new normal’ that supports flexible workplace practices, and in accordance with UNCRPD goals of inclusive employment and reducing disability inequity, we argue that the pathway for people with disability as career researchers needs an ethical review and overhaul. We provide readers with a practical roadmap to advance a more inclusive academy for researchers with disability.

Abstract

This chapter reviews the evidence on the role of physicians in shaping inequalities in access to and utilisation of healthcare. The authors examine three types of physician decisions that can influence inequalities in access and utilisation: location decisions, decisions to work in the public and/or private sector, and decisions or behaviours in the doctor–patient encounter. For each, the authors summarise the issues and empirical evidence on possible policies to help reduce inequalities in access. Future research to reduce inequalities should focus on changes to health systems that influence physician decisions, such as health insurance expansions, the public–private mix and financial incentives, as well as physician training and policies for a more diverse physician workforce.

Abstract

Patriotism is often described as the “love of country” that individuals display in the acclamation of their national community. Despite the prominence of this sentiment in various societies around the world, organizational research on patriotism is largely absent. This omission is surprising because entrepreneurs, human resource (HR) divisions, and firms frequently embrace both patriotism and patriotic organizational practices. These procedures include (among other interventions) national symbol embracing, HR practices targeted toward military members and first responders, the adulation of patriots and celebration of patriotic events, and patriotic-oriented corporate social responsibility (CSR). Here, the authors argue that research on HR management and organization studies will likely be further enhanced with a deeper understanding of the national obligation that can spur employee productivity and loyalty. In an attempt to jumpstart the collective understanding of this phenomenon, the authors explore the antecedents of patriotic organizational practices, namely, the effects of founder orientation, employee dispersion, and firm strategy. It is suggested that HR practices such as these lead to a patriotic organizational image, which in turn impacts investor, customer, and employee responses. Notably, the effect of a patriotic organizational image on firm-related outcomes is largely contingent on how it fits with the patriotic views of other stakeholders, such as investors, customers, and employees. After outlining this model, the authors then present a thought experiment of how this model may appear in action. The authors then discuss ways the field can move forward in studying patriotism in HR management and organizational contexts by outlining several future directions that span multiple levels (i.e., micro and macro). Taken together, in this chapter, the authors introduce a conversation of something quite prevalent and largely unheeded – the patriotic organization.

Abstract

The COVID-19 pandemic struck roughly halfway through the execution of my dissertation research: an investigation of single-person business ownership as an alternative form of work. As the pandemic continued on its course, I was fortunate enough to be able to reconnect with many of my informants to find out how they had weathered the crisis. In this article, I review ethnographically the strategies pursued by some nonemployers to weather the economic storm, including follow-up interviews and the results of a survey of North Carolina nonemployer business owners covering how they had fared during the pandemic. Finally, I close by considering nonemployer resilience as a function of the agency they are able to exercise over the way they work.

Abstract

Research indicates a long historical connection between racism and nationalist ideologies. This connection has been highlighted in the resurgence of exclusionary nationalism in recent years, across many multicultural societies. This chapter discusses the notions of race, ethnicity and nation, and critically examines how racism shapes contemporary manifestations of nationalist discourse across the world. It explores the historical role of settler-colonialism, imperial expansions and the capitalist development in shaping the racial/ethnic aspect of nationalist development. Moreover, it provides an analysis of the interconnections between the racialisation of minorities, exclusionary ideologies and the consolidation of ethno-nationalist tropes. This chapter further considers the impact of demographic changes in reinforcing anti-migrant exclusionary sentiments. This is examined in connection with emerging nativist discourse, exploring how xenophobic racism has shaped and is shaped by nostalgic nationalism based on the sanitisation of the legacies of Empire and colonialism.
