This study explores the relationship between inequality and structural transformation by constructing a theoretical model, developing analytical frameworks, and implementing a case study. The general equilibrium model we develop demonstrates that inequality exhibits an inverted U shape as...

Research has not yet been undertaken on the optimal level of urbanization, notwithstanding the pioneering work of Au and Henderson (2006) on optimal urban concentration. This paper develops two-sector general equilibrium models of urbanization, with and without equity consideration,...

Despite a growing literature on population aging, empirical studies exploring mechanisms between aging and income inequality are scarce. This paper estimates the impact of aging on inequality via the perspective of labor income share, based on cross-country information covering the period...

Population aging has significant economic and social costs, and this paper studies its impacts on inequality, both theoretically and empirically. First, we build a two-period overlapping-generation model with an uncertain lifetime and find that population aging has the overall effect of...

This paper assesses the effects of the most recent monetary policy behavior of the Bank of Japan (BOJ) (in particular, zero interest rate policy and negative interest rate policy) and Japanese tax policy on income inequality in this country during the period of 2002Q1 to 2017Q3. The vector error...

From April 2013 until May 2016, Japan's monetary base rose from ¥155 trillion to ¥387 trillion as part of the Bank of Japan's (BOJ) quantitative and qualitative easing (QQE) monetary policy for achieving a price stability target of 2%. Although the main objective of the BOJ's quantitative...

This paper introduces a new index of financial inclusion for 153 advanced, emerging, and developing economies using a comprehensive set of new indicators, grouped into four different dimensions: financial access, usage, financial development, and fintech infrastructure. The fintech...

This paper examines the relationship between infrastructure development and income inequality in urban People's Republic of China. Recent policies target reductions in income inequality while increasing sustainable urban development. Infrastructure investment plays a key role in achieving both...

This paper examines the relationship between city size, migration, and urban income inequality using the 1% sample of the 2005 Census in the People's Republic of China (PRC). We calculate various measures of within-city income inequality for 252 PRC cities. It is found that city income...

Using a case study about rural Tianjin and Shandong provinces, we try to explain what mechanism affects income inequality in rural areas, especially how rural dual structural transformation leads to the income inequality "inverted-U" Curve in some developed areas in the People's Republic of...
