The extant literature on status-signalling primarily adopts Veblen’s theory of class to caste and racial identities. This study aims to adopt a more suitable theoretical lens that is more relevant not only for class identities, but also for other identities such as caste and race. By viewing...
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...

Because colonial ethnic spatial demarcations were also unequally...
