There has been wide interest in private supply of roads as a solution to traffic congestion. We study its efficiency under demand uncertainty: we solve for equilibrium and optimum as benchmarks, and evaluate the efficiency of possible regulatory policies for private road operators. We obtain...

We study the efficiency of private supply of roads under demand uncertainty and evaluate various regulatory policies. Due to demand uncertainty, capacity is decided before demand is known but tolls can be adjusted after demand is known. Policy implications can differ considerably from those...

We analyse congestion pricing in a road and rail network with heterogeneous users. On the road there is bottleneck congestion. In the train there is crowding congestion. We separately analyse proportional heterogeneity that varies the values of time and schedule delay scalarly in fixed...

Drawing on global media reports, we conduct a sentiment analysis of the image of China's Belt and Road Initiative (BRI) and the evolution of its image over time. Our main finding is that perceptions of the initiative deteriorated significantly in many geographies from 2017 to 2022. The notable...

Since China's Belt and Road Initiative (BRI) was announced almost a decade ago, circumstances in global politics have changed radically. The trade war between the United States and China, and most recently the Covid-19 pandemic have caused a partial reshuffling of the international economic...
