Based on required growth rate and actual growth rate, this paper proposes a method to construct measures to indicate the probability of a country escaping the middle income trap (MIT). A second contribution of this paper is to model this probability using 1960–2015 cross-country data, focusing...

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...

Income distribution is perceived to affect crime (Becker 1968; Thurow 1971; Merlo 2003). Consequently, economists have been modeling crime-employing inequality indicators as one of the explanatory variables, yielding mixed results. This paper argues that income polarization rather than inequality should...

Purpose - The major marine functional zoning plan (MMFZP) and marine functional zoning (MFZ) are two important kinds of marine spatial planning (MSP) in China. Their developing and implementation are integral to rational marine utilization and sustainable marine development. The purpose of this...

The ratio of long- to short-term dividend prices, “price ratio” (pr), predicts annual market return with an out-of-sample R2 of 19%, subsuming the predictive power of price-dividend ratio (pd). After controlling for pr, pd predicts dividend growth with an out-of-sample R2 of 30%. Our results...

Delegation bears an intrinsic form of uncertainty. Investors hire managers for their superior models of asset markets, but delegation outcome is uncertain precisely because managers' model is unknown to investors. We model investors' delegation decision as a trade-off between asset return...
