A Different Perspective on the Evolution of UK Income Inequality

This paper scrutinizes the conventional wisdom about trends in UK income inequality and also places contemporary inequality in a much longer historical perspective. We combine household survey and income tax data to provide better coverage of all income ranges from the bottom to the very top (and make our estimates available to other researchers). We make a case for studying distributions of income between tax units (i.e. not assuming the full income sharing that goes with the use of the household as the unit of analysis) for reasons of principle as well as data harmonization. We present evidence that income inequality in the UK is as least as high today as it was just before the start of World War 2.     

Exploring consumer attitudes to online collaborative consumption: A typology of collaborative consumer profiles

Online collaborative consumption enhances peer networks, members of which communicate, collaborate, and even deliver services to one another via digital sharing platforms. Despite the tremendous increase in collaborative consumption, due in large part to the development of the Internet, the reality of the economic and social movements that underpin this trend is much less visible. Of course, not all consumers seek collaborative consumption or interact through online platforms. Using a qualitative approach, this paper aims to investigate motivational factors and barriers against collaborative consumption and to establish a typology of collaborative consumer profiles, identifying the most suitable type of online sharing platforms for each profile. The findings reveal the following collaborative consumer profiles: committed, pragmatists, intermittent, and skeptical, each demonstrating different preferences for the different type of online sharing platform.     

The Uncertainty of Academic Rent and Income Inequality: The OECD Panel Evidence

The article presents an alternative view on the education—income inequality relationship, which calls into question the neoclassical claim that education increases labor productivity and hence contributes to a higher output, wage and consequently more even income distribution. In the context of public policies, education needs to be seen not only as a factor of income mobility, but also as a “positional good,” which benefits graduates at the expense of non-graduates. Education generates “academic rent,” by which we mean uneven remuneration of workers based on academic signs of distinctions that do not necessarily reflect differences in productivity. Using the robust panel model on a sample of OECD (Organization of Economic Co-operation and Development) countries from 1980 to 2015, we show that investments in human capital lead to lower inequality, but overinvestments tends to increase income inequality, which may be related to academic rent. In discussing this result, we consider that uncertainty of academic rent under the condition of a rapid transformation of the workplace caused by the fourth industrial revolution.     

Informal Employment and the Structure of Wages in India: A Review of Trends

The “alternative”, “atypical” or “informal” workforce has grown in developed and developing countries alike. One of the more recent evolutions of informal employment has been of informal employment within formal enterprises. In the interest of flexibility and cost‐reduction, many formal firms increasingly resort to hiring workers on a temporary or informal basis. Alongside, and perhaps, as a result of the persistence and pervasiveness of informal employment, issues relating to inequality have come to the fore. This paper is motivated by these two intertwining aspects of Indian labor market—informality and wage inequality. Using nationally representative sample data, the paper examines trends in wage inequality among various forms of informal workers, overlaying these findings with broader trends in inequality. Using a regression based inequality decomposition, the paper compares the sources of wage inequality across different employment groups and the reasons for differences in wage inequality.     

Critical representations of Southern African inequality: Transcending outmoded exhibition and museum politics

ABSTRACT

Illustrating inequality to a more general public – beyond those concerned purely with public policy and research – presents various challenges. Museums have often served a function of memorialising both the impressive steps forward and major barriers to social progress, as a form of remembrance and understanding, although the twentieth century format in South Africa was generally embedded within colonial and racist self-glorification. The potential to transcend outmoded exhibition and museum politics with a new approach based on dialogical not didactic presentation, arises with inequality. In this exploration of how such an approach might unfold in the world's most unequal major city (as judged by the Palma Ratio), Johannesburg, the concept of threshold is introduced. Physical and conceptual access through overcoming thresholds is explored through a specific site, the Old Post Office, and through two artifacts that reveal structural power that generates inequality: Durban's sanitation system and Eastern Zimbabwe's diamond fields.     

TEN YEARS OF GENERAL OLIGOPOLISTIC EQUILIBRIUM: A SURVEY

In this paper, I survey the recent and rapidly increasing theoretical literature using the brand‐new approach in embedding oligopolistic competition in general equilibrium, as designed by J. Peter Neary. First, I introduce the reader to Neary's approach, by describing the main ingredients. Then, I present a comprehensive set of studies that, over the last decade, apply this approach in different contexts, most of which are in open economy, and I examine the relevant outcomes. Although the theoretical literature has generously advanced, there is a lack of research on the empirical side, which would be an important area for future research besides theoretical extensions, some of which I highlight in the conclusions.     

Political capitalism: The interaction between income inequality,economic freedom and democracy

We study the relationship between income inequality and economic freedom for a panel of 100 countries for the 1971–2010 period. Using a panel Granger non-causality approach, we reject the null hypothesis of Granger non-causality running from income inequality to economic freedom, but not vice versa. From a series of dynamic panel estimations we show that the effect of income inequality on economic freedom is negative and robust to the inclusion of additional controls. In particular, inequality is negatively associated with those components of economic freedom related to international trade, domestic market regulation as well as the rule of law and property rights protection. We argue that the negative effect of inequality on economic freedom is due to the economic elite converting its economic power into de facto political power to defend its economic interests; these interests run counter to economic freedom, discouraging innovation and competition as well as protecting the elite's rents. Finally, we show that economic freedom decreases with income inequality even in democratic countries, suggesting that democratic institutions do not prevent economic freedom from eroding. We argue that the latter finding corresponds to a system of political capitalism or captured democracy, where a powerful economic elite can nevertheless exercise de facto political power by cooperating with politicians and other decision-makers for their mutual benefit.     

Potential Impact of Climate Change and Armed Conflict on Inequality in Sub-Saharan Africa

This study investigates the potential impact of climate change and armed conflict on inequality in Sub-Saharan Africa (SSA). The system-GMM for a panel of 35 SSA countries is employed using annual data from 1997 to 2018. The empirical results indicate that armed conflict and climate are major drivers of inequality in SSA. The direct impact of the two determinants is more than the indirect impact. Also, the impact of armed conflict is more than the climate change. The coefficients of population growth, output growth, unemployment, natural rent, exchange rate and inflation rate are significant positive predictors of inequality in the SSA. The study advocates for a multidisciplinary inclusive growth strategy that prioritises the climate change reversal, de-escalation of armed conflict, population control, reduction of the unemployment rate and increasing informal sector productivity, to promote inclusive growth and reduce inequality. However, sequencing the policy targets relative to the magnitude of their impact on inequality is extremely crucial.
