This paper seeks to understand whether the way in which inequality is communicated through measurements influences individuals’ fairness perceptions regarding wealth inequality. It begins from the premise that prominent measures of inequality, such as the Gini coefficient, fall short of providing an...

– Examples from rational choice theory and behavioural economics
Using illustrations from research on inequality, this essay makes a case for ‘behavioural synthesis’, that is the reconciliation between neo-classical and behavioural economics. Focusing on selected theories of absolute and relative inequality, we first give a brief critique of utilitarian models...

– A k-means approach
This paper employs k-means clustering, a multidimensional pattern recognition method, to categorize countries using information from five Varieties of Democracy indices. K-means country clusters are similar but not entirely identical to both k-medians clusters and arbitrary groups formed using only...

– Trends, policies, and controversies
Reducing poverty and inequality and promoting inclusive growth are fundamental to achieving the UN Sustainable Development Goals (SDGs), approved by the UN General Assembly in September 2015. The first target of SDG1 is to eradicate extreme poverty, while SDG10 focuses on reducing inequality within...
Research on how income inequality affects borrowing behaviour reignited after the 2008 global recession. One prevailing theory is that rising income inequality in the US and other high-income economies eroded real household incomes and prompted more and more borrowing. This growing debt culminated...
Many countries today experience increasing or persistent income inequality, a major concern for citizens and politicians alike. This concern is justified; as some individuals get richer, most people’s real incomes stagnate. Widening income inequality brings challenges to a nation’s development...

– The role of different parts of the income distribution
In this paper we reassess the relationship between inequality and human development, focusing on the differential effect associated with the concentration of national income at different parts of the income distribution. To do so, we rely on a large global panel of countries over the last decades...
– Structural Transformation, Inequality Dynamics, and Inclusive Growth
The developer’s dilemma is thus: developing countries seek inclusive economic development — i.e., structural transformation — sufficiently broad-based to raise the income of the poor. Inclusive economic growth requires falling income inequality to maximise income growth at the lower end of the...

According to the World Bank, Indonesia has reached the upper-middle income status in 2019 after spending almost two decades in the lower-middle income country group. Despite the setback of COVID-19 the Indonesian government aspires to become a ‘developed’ country by 2045, when the country will...

There are multiple pathways of structural transformation and different inequality dynamics of each. Rising inequality is not inevitable — policies make a difference. Broad-based economic development requires public policies to address any upward pressure on inequality. A different policy agenda for...
