We present a time-dependent Langevin description of dynamics of stock prices. Based on a simple sliding-window algorithm, the fluctuation of stock prices is discussed in the view of a time-dependent linear restoring force which is the linear approximation of the drift parameter in Langevin...

We propose an extended public goods interaction model to study the evolution of cooperation in heterogeneous population. The investors are arranged on the well known scale-free type network, the Barab\'{a}si-Albert model. Each investor is supposed to preferentially distribute capital to pools in...

This paper represents an early attempt to analyze the comprehensive relationship between public educational expenditure and structural change, which is often measured by labor transfer from agricultural sector to industrial sector in developing economies. I construct a two-sector general...

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...

Certain stylized facts are common among successful economic latecomers: an inverse U-shaped gross domestic product and capital per capita growth rate, high growth rates during the catch-up period, and rapid structural changes. This paper, for the first time, proposes a general equilibrium...

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,...

Urban road infrastructure is crucial in determining air pollution. Yet, little is known about the roles played by road width vs. road length. This paper attempts to fill this gap by estimating the effects of road infrastructure on 10-micron particulate matter (PM10) using city-level data from...

Changes in the labor share of national income affect inequality (Piketty 2014). This paper aims at investigating the relationship between the labor share and technical progress, based on provincial data of the People's Republic of China (PRC) from 1978 to 2012. Our main empirical results show...

Successful economic latecomers have certain stylized facts: an inverse U-shaped growth rate, high growth rates of per capita output with high capital returns, and rapid structural changes. In this paper, we document for the first time a catch-up cycle that successful latecomers likely...

The increasing attention on Bitcoin since 2013 prompts the issue of possible evidence for a causal relationship between the Bitcoin market and internet attention. Taking the Google search volume index as the measure of internet attention, time-varying Granger causality between the global Bitcoin...
