In large parts of the world, income inequality has been rising in recent decades. Other regions have experienced declining trends in income inequality. This raises the question of which mechanisms underlie contrasting observed trends in income inequality around the globe. To address this research question in an empirical analysis at the aggregate level, we examine a global sample of 73 countries between 1981 and 2010, studying a broad set of drivers to investigate their interaction and influence on income inequality. Within this broad approach, we are interested in the heterogeneity of income inequality determinants across world regions and along the income distribution. Our findings indicate the existence of a small set of systematic drivers across the global sample of countries. Declining labour income shares and increasing imports from high-income countries significantly contribute to increasing income inequality, while taxation and imports from low-income countries exert countervailing effects. Our study reveals the region-specific impacts of technological change, financial globalisation, domestic financial deepening and public social spending. Most importantly, we do not find systematic evidence of education’s equalising effect across high- and low-income countries. Our results are largely robust to changing the underlying sources of income Ginis, but looking at different segments of income distribution reveals heterogeneous effects.

The authors' work aims to identify the employer-specific drivers of the college (or university) wage gap, which has been identified as one of the major determinants of the dynamics of overall wage and income inequality in the past decades. The authors focus on three employer-level features that can be associated with asymmetries in the employment relation orientation adopted for college and non-college-educated employees: (1) size, (2) the share of standard employment and (3) the pervasiveness of incentive pay schemes.

The authors' establishment-level analysis (data from the Basic Survey on Wage Structure (BSWS), 2005–2018) focusses on Japan, an economy characterised by many unique economic and institutional features relevant to the aims of the authors' analysis. The authors use an adjusted measure of firm-specific college wage premium, which is not biased by confounding individual and establishment-level factors and reflects unobservable characteristics of employees that determine the payment of a premium. The authors' empirical methods account for the complexity of the relationships they investigate, and the authors test their baseline outcomes with econometric approaches (propensity score methods) able to address crucial identification issues related to endogeneity and reverse causality.

The authors' findings indicate that larger establishment size, a larger share of regular workers and more pervasive implementation of IPSs for college workers tend to increase the college wage gap once all observable workers, job and establishment characteristics are controlled for. This evidence corroborates the authors' hypotheses that a larger establishment size, a higher share of regular workers and a more developed set-up of performance pay schemes for college workers are associated with a better capacity of employers to attract and keep highly educated employees with unobservable characteristics that justify a wage premium above average market levels. The authors provide empirical evidence on how three relevant establishment-level characteristics shape the heterogeneity of the (adjusted) college wage observed across organisations.

The authors' contribution to the existing knowledge is threefold. First, the authors combine the economics and management/organisation literature to develop new insights that underpin the authors' testable empirical hypotheses. This enables the authors to shed light on employer-level drivers of wage differentials (size, workforce composition, implementation of performance-pay schemes) related to many structural, institutional and strategic dimensions. The second contribution lies in the authors' measure of the “adjusted” college wage gap, which is calculated on the component of individual wages that differs between observationally identical workers in the same establishment. As such, the metric captures unobservable workers' characteristics that can generate a wage premium/penalty. Third, the authors provide empirical evidence on how three relevant establishment-level characteristics shape the heterogeneity of the (adjusted) college wage observed across organisations.

This chapter does three things. First, it estimates regional gross domestic product (GDP) for three different geographical levels in Switzerland (97 micro regions, 16 labor market basins, and 3 large regions). Second, it analyzes the evolution of regional inequality relying on a heuristic model inspired by Williamson (1965), which features an initial growth impulse in one or several core regions and subsequent diffusion. Third, it uses index number theory to decompose regional inequality into three different effects: sectoral structure, productivity, and comparative advantage.

The results can be summarized as follows: As a consequence of the existence of multiple core regions, Swiss regional inequality has been comparatively low at higher geographical levels. Spatial diffusion of economic growth occurred across different parts of the country and within different labor market regions. This resulted in a bell-shaped evolution of regional inequality at the micro regional level and convergence at higher geographical levels. In early and in late stages of the development process, productivity differentials were the main drivers of inequality, whereas economic structure was determinant between 1888 and 1941. The poorest regions suffered from comparative disadvantage, that is, they were specialized in the vary sector (agriculture), where their relative productivity was comparatively lowest.

The purpose of this paper is to analyze the inequality of opportunity among Indonesian school-age children from 2002 to 2012. It focuses on the possibilities of accessing basic needs, such as primary education, secondary education, electricity and clean water.

This paper used three interrelated indicators, namely, coverage access rate, dissimilarity index and human opportunity index. It also applied Shapley decomposition to measure the contributions of each determinant of inequality opportunities. These data were obtained from the National Household Survey conducted in 2002-2012.

This study revealed that the level of access to all basic needs, except clean water, was likely to increase with even distribution during the observation period. Moreover, the decomposition results showed that the education of household heads, household income and region (rural-urban) were the main contributors to the total inequality of opportunity.

This study on the inequality of opportunity is interesting, for it is tightly related to inequality of outcome, i.e. income, expenditure and wealth. It is arguable that the inequality of outcome, nowadays, is a reflection of the past inequality in basic opportunities. Thus, the exploration of potential inequality drivers begins to be increasingly important, as it can assist the policymakers in drawing effective policies to repress the increasing trend of future inequality.

The importance of social exclusion and the disadvantage experienced by many minority ethnic and religious populations are rooted in SDG 10. To address this exclusion effectively it is important to understand their key drivers. This paper aimed to establish the key drivers of exclusion and their outcomes in Nigeria.

The methods involved a scoping review of literature and stakeholder workshops that focused on drivers of social exclusion of religious and ethnic minorities in public institutions.

At the macro level, the drivers include ineffective centralized federal State, competition for resources and power among groups, geographic developmental divide and socio-cultural/religious issues. At the meso-level are institutional rules and competition for resources, stereotypes and misconceptions, barriers to access and service provision. At the micro-level are socio-economic status and health-seeking behaviour. The perceived impact of social exclusion included increasing illiteracy, lack of employment, deteriorating health care services, increased social vices, communal clashes and insurgencies and vulnerability to exploitation and humiliation. These drivers must be taken into consideration in the development of interventions for preventing or reducing social exclusion of ethnic and religious minorities from public services.

This is a case of co-production by all the stakeholders and a novel way for the identification of drivers of social exclusion in public services in Nigeria. It is the first step towards solving the problem of exclusion and has implications for the achievement of SDG 10 in Nigeria.

The purpose of this chapter is to analyse how in recent years the rediscovery that extreme inequality is returning to advanced economies and has become widespread. What is at issue are the causes of this inequality. It is becoming clear that the wider population, particularly in Anglo-American economies have not shared in the growing wealth of the countries concerned, and that the majority of this wealth is being transferred on a continuous and systemic basis to the very rich. Corporate governance and the pursuit of shareholder value it is argued has become a major driver of inequality.

The current statistical evidence produced by leading authorities including the US Federal Reserve, World Economic Forum, Credit Suisse and Oxfam are examined. The policy of shareholder value and the mechanisms by which the distributions from business take place are investigated from a critical perspective.

While the Anglo-American economies are seeing a return to the extremes of inequality last witnessed in the 19th century, the causes of this inequality are changing. In the 19th century great fortunes often were inherited, or derived by entrepreneurs from the ownership and control of productive assets. By the late 20th century as Atkinson, Piketty and Saez (2011) and others have highlighted, the sustained and rapid inflation in top income shares have made a significant contribution to the accelerating rate of income and wealth inequality.

The intensification of inequality in advanced industrial economies, despite the consistent work of Atkinson and others, was largely neglected until the recent research of Picketty which has attracted international attention. It is now acknowledged widely that inequality is a serious issue; however, the contemporary causes of inequality remain largely unexplored.

The significance of inequality, now that it is recognized, demands policy and practical interventions. However, the capacity or even willingness to intervene is lacking. Further analysis of the debilitating consequences of inequality in terms of the efficiency and stability of economies and societies may encourage a more robust approach, yet the resolve to end extreme inequality is not present.

The analysis of inequality has not been neglected and this chapter represents a pioneering effort to relate the shareholder value orientation now dominant in corporate governance to the intensification of inequality.

The purpose of this paper is to study what happens when firms misuse customers’ information and perceptions of unfairness arise because of privacy concerns. It explores a unifying theoretical framework of perceptions of unfairness, explained by the advantaged–disadvantaged (AD) continuum. It integrates the push, pull and mooring (PPM) model of migration for understanding the drivers of unfairness.

The paper is conceptual and develops a theoretical model based on extant research.

Using the PPM model, the paper explores the effects of information-based marketing tactics on the AD framework in the form of two types of customers. Findings from the review suggest that three variables have a leading direct effect on the AD customers. Traditionally, the fairness literature focuses on price, but findings show that service and communication variables impact customers’ unfairness perceptions. This paper examines the importance of these variables, in the context of an AD framework, to help explain unfairness and consider the implications.

To explain information misuse and unfairness perceptions, the paper develops a unifying theoretical framework of perceptions of unfairness, explained by linking the PPM model of migration with the AD continuum.

The authors explore the Australian Government's implementation of budgetary measures to manage the social and economic impacts of COVID-19, paying particular attention to how the country's history of inequality has shaped these actions, and the effect inequality may have on outcomes.

In this qualitative case study of public budgeting, the authors draw on the latest research into inequality to consider the implications of policy responses to COVID-19 in Australia. In particular, we examine the short-term introduction of what we term “people-focused” budgetary measures. These appeared contrary to the dominant neoliberalist approach to Australian welfare policymaking.

This paper foregrounds the relationship between budgeting, public policy and inequality and explores how decades of increasingly regressive tax systems and stagnating living wages have made both people, and the state, vulnerable to crises like COVID.

There is still much to learn about the role of accounting in the shaping of growing economic inequality. In focusing on public budgeting within the context of COVID, the authors suggest ways accounting researchers can contribute to our understanding of economic inequality, both in terms of drivers and consequences. The authors hope to contribute to a growing body of accounting research that can influence social movements, political debates and policymaking, while also raising awareness of the consequences of wealth and income inequality.

The authors explore ways accounting scholars might help articulate a post-COVID future that avoids recreating the inequalities of the past and present.

With the recognition that generating economic growth is not the same as sustaining it, the challenge to catch-up and growth literature is discerning between these processes. Recent research suggests that the decline in the frequency of “shrinking” episodes is more important for long-term development than higher growth rates. By using a framework centred around social capabilities, this study aims to investigate the effects of income inequality and poverty on economic shrinking frequency, as opposed to previous literature that has exclusively had a growth focus. The aim is to investigate how and why some societies might be more resilient to economic shrinking.

The research is a quantitative study, and the authors build a longitudinal data set including 23 developing countries throughout 42 years to test the paper’s purpose. This study uses country and period fixed-effects specifications as well as cross-sectional graphical representations to investigate the relationship between proxies of economic inclusivity and the frequency of shrinking episodes.

The authors demonstrate that while inclusive societies are more resilient to shrinking overall, it is changes in poverty levels, but not changes in income inequality, that appear to be correlated with economic shrinking frequency. Inequality, while still an important element to explain countries’ growth potential as an initial condition, does not seem to make the sample more resilient to shrinking. The authors conclude that the mechanisms in which poverty and inequality are correlated with the catch-up process must run through different channels. Ultimately, processes that explain growth may intersect but not always overlap with the ones that explain resilience to shrinking.

The need for inclusive growth in long-term development has been championed for decades, yet inclusion has seldom been explored from the shrinking perspective. Though poverty reduction is already an important mainstream political objective, this paper differentiates itself by providing an alternate viewpoint of why this is important. Income inequality could have more of an economic growth limiting effect, while poverty reduction could be required to build resilience to economic shrinking. Developing countries will need both growth and resilience to shrinking, to catch-up with higher-income economies, which policymakers might need to balance carefully.
