This paper studies arbitrage-free conditions for multiperiod asset pricing in frictional financial markets with proportional transaction costs. We consider the Euclidean space for weakly arbitrage-free security markets and strongly arbitrage-free security markets, and establish the weakly...

Carbon-based border tax adjustments (BTAs) have recently been proposed by some OECD countries to level the carbon playing field and target major emerging economies. This paper applies a multi-sector dynamic computable general equilibrium (CGE) model to estimate the impacts of the BTAs...

The rapidly developing online food delivery business is a novel “ecosystem” involving digital platforms, restaurants, delivery-workers, and customers. Continuous expansion of its market size is accompanied by problems of economic fairness such as “wage distribution” and “revenue...

This paper proposes a new class of nonlinear interval models for interval-valued time series (ITS). By matching the interval model with interval observations, we develop a nonlinearminimum-distance estimation method for the proposed models, and establish the asymptotictheory for the proposed...

This monograph consists of two parts. One part is portfolio selection theory and the other part is capital asset pricing theory. For each part, a comprehensive review of the original theory, efforts to improve the theory afterwards and future works to be done are presented. Some innovative...

With large shares in global trade and carbon emissions, China's international trade is supposed to be significantly affected by the proposed carbon-based border tax adjustments (BTAs). This paper examines the impacts of BTAs imposed by the USA and EU on China's international trade, based on a...
