Project

Performance-based Regulation of Mass Transit Railway’s Reliability Performance (港鐵可靠性的績效監管)
To inform a future policy debate on MTR’s reliability performance, the project estimates the economic cost of MTR customers due to travel delays during a service disruption. Using statistical modeling of telephone responses to a contingent valuation survey by ~1,500 respondents, our proposed estimation aims to precisely quantify MTR customers’ willingness to pay (WTP) for avoiding a service disruption. Using these WTP estimates, the project calculates annual aggregate customer costs (HK$M per ye . . .

Estimation of Electricity and Transportation Demand
To solve real-world problems in electricity and transportation, this project uses parsimonious regression systems to document the limited effectiveness of price-management of demand because of the low price elasticity estimates for (a) retail energy demands in North America and Hong Kong; and (b) tunnel usage patterns in Hong Kong.
Project Start Year: 2019, Principal Investigator(s): WOO, Chi Keung 胡志強
 
A New Process to Fairly Score Individual Contributions to a Team Project
We develop a new, fair, relatively easy to implement, low-cost and generalizable process to score individual contributions to a team project – an innovative solution to the common problem of free riding faced by teachers in higher education.
Project Start Year: 2018, Principal Investigator(s): WOO, Chi Keung 胡志強
 
Energy Policy
Energy policy initiatives can have a significant impact on electricity market prices. Recognizing the information needs of private companies and government agencies, Prof Woo has been working with researchers in Hong Kong, Canada, Israel and the U.S. to address the following substantive policy questions: • What are the price effects of energy policy programs on wholesale electricity prices in California and other states in the Western Interconnection (WI) of the U.S.? • Do these price effects . . .

Price Elasticities of Electricity and Gas Demands by End-use Customer Class in Hong Kong
This project estimates Hong Kong's price elasticities of demand for electricity and gas for three end-use customer classes: residential, commercial and industrial. It uses the estimates thus obtained to address public policy questions in connection to Hong Kong's elecricity future in the next 30 years.
Project Start Year: 2016, Principal Investigator(s): WOO, Chi Keung 胡志強
 
Price Responsiveness of Electricity and Natural Gas Demands by Customer Class in the US
To inform the global efforts in deep decarbonization, this project uses publicly available data to estimate the price responsiveness of the demands for electricity and natural gas by customer class. When completed, the price responsiveness estimates to address questions related to the energy future of the U.S. and other parts of the world.
