Taxi Driver Learns Dynamic Spatial Equilibrium

I use three equilibrium concepts in the sciences to study the dynamics of taxi transportation. At the microscopic level, I formalized taxi drivers' decision-making as an income-maximizing optimization, which collectively establishes an economic …

Demand, Supply and Performance of Street-Hail Taxi

I use in-vehicle Global Positioning System (GPS) data to estimate the supply and demand of street-hail taxis at segment level of a road network, without surveilling the population. To this end, I model taxi demand and supply as non-stationary Poisson …

Environmental Economics and Uncertainty: Review and a Machine Learning Outlook

Economic assessment in environmental science is often subject to limited or costly data, and thus it is important to properly characterize the uncertainty associated with impact assessment. We review the issue of uncertainty in integrated assessment …
