Purpose: The purpose of this paper is to devise a efficient method for the importance analysis on Port Throughput Influence Factors. Design/methodology/approach: Neighborhood rough sets is applied to solve the problem of selection factors. First the throughput index system is established. Then,...

Purpose: The purpose of this paper is to develop a combined model composed of grey-forecast model and Logistic-growth-curve model to improve the accuracy of forecast model of cargo throughput for the port. The authors also use the existing data of a current port to verify the validity of the...

Purpose: There is a widespread recognition of the importance of correctly modeling service processes as an effective way to provide a comprehensive understanding of the process and to enhance the service quality to clients. Taking this into account, this paper aims to construct the logistics...

Using data from a large online education platform with more than 100,000 gig workers, we investigate the causal impact of the COVID-19 pandemic on gig economy labor supply and quantify how much of the impact can be attributed to lockdown policies. The average labor supply on the gig economy...

What determines firms’ decisions to exit Russia because of the Ukraine invasion and do investors appreciate firms’ social image management? We test five potential firm motives, the reputation concern and social sanction channel, the altruism channel, the institution and law origin channel,...

We study how shared experiences of political events can have a long-term effect on consumers' identity-driven brand choices, and how geopolitical conflicts can activate the effect. Our empirical strategy uses a generalized difference-in-differences design to exploit spatial variations in the...
