Due to the COVID-19 pandemic, global demand for coal has experienced a significant drop - and air quality has improved accordingly. In a virtual seminar moderated by Program on Energy and Sustainable Development (PESD) Director Frank Wolak, PESD Associate Director Mark Thurber offered his assessment on whether the reduced role of coal and other fossil fuels is likely to be permanent, or whether they will emerge stronger than ever when the pandemic is over.

Unconventional natural gas and the technologies developed to extract it in the U.S. point to a possible lower carbon energy future for China that can be facilitated through international cooperation between them, improving China's reliance on domestically produced coal, and creating economic and environmental benefits for both countries as well as the rest of the world.

Last week, Stanford's Board of Trustees announced that the university would not directly invest funds from its endowment in coal mining companies.  Even the strongest advocates of this action acknowledge that it is a symbolic gesture with little direct effect on the coal industry or global greenhouse gas emissions.  But if a university administration wants to take symbolic (or real) action on climate change, is coal investment a wise choice?

From 1996 to 2006, China’s oil consumption growth far exceeded that of all major consuming countries. China’s average growth in oil consumption over the time period 2000 to 2006 was estimated to be approximately 8 percent per year, up from 6 percent per year from 1996 to 2000. One factor alleged to have caused this rapid increase in the growth of oil consumption in China is the under-pricing of oil to domestic consumers--selling oil-derived products such as gasoline and diesel fuel domestically at prices that are less than the world oil price plus the cost of producing that product. We explore validity of this claim, quantify the extent to which oil domestic oil consumption is subsidized by the Chinese government, and assess the impact of these subsidies on China’s demand for oil. We find economically significant evidence of under-pricing of gasoline and diesel fuel by China relative to the US over our sample period of January 2005 to July 2008 for all of the approaches to computing the comparable price of these products for the two countries. We estimate that underpricing of oil in the form of gasoline and diesel fuel in China resulted in a total subsidy to Chinese consumers of between 5 and 15 billion dollars in 2007. We also analyze the likely change in the consumption of gasoline and diesel in 2007 that would result from the elimination of this underpricing and find that it had little impact on gasoline and diesel fuel consumption for short-run own-price elasticities in the range of recent estimates of these magnitudes from cross country studies.

A spatial equilibrium model of the world coal market is developed that accounts for coal to natural gas switching in the electricity sector in the United States and Europe, the potential for China to exercise monoposony power in its coal purchasing behavior, and the impact of increasing the western US coal export port capacity. The global coal market equilibrium is computed as the solution to a nonlinear complementarity problem. Where possible parameters of the model are estimated econometrically. Where this is not possible the parameters are calibrated to global coal market outcomes in 2011. The model is used to assess how the shale gas boom in the United States impacts global coal market outcomes for dierent models of Chinese coal buyers' purchasing behavior and dierent scenarios for the capacity of coal export terminals on the US west coast.  Although reductions in US and European natural gas prices reduce coal consumption in the US and Europe, the percentage reduction in coal consumption in Europe is much less than that in the US. Increasing US west coast port capacity increases coal exports from the western US and reduces Chinese coal production. US coal prices increase which causes more coal to natural gas switching in the US, further reducing global greenhouse gas emissions. Modeling China as a monopsony buyer of coal reduces the absolute magnitude of these impacts.

Recent behavioral models of reference-dependent or context-dependent preferences have posited that consumers form reference points or consideration sets based on expectations. We investigate this hypothesis empirically within the retail gasoline market. Given that gasoline consumers have been shown to form price expectations based on past price lev- els, reference- or context-dependence would likely cause gasoline demand to become more price-sensitive when prices are high relative to the recent past (i.e., higher than expected). Consistent with these predictions, we find that gasoline demand in the U.S. is up to three times more elastic when prices rise above their average over the previous year than when prices fall below this average. Reference-price effects vary substantially across cities with different demographic and commuting patterns, and cities that have less elastic demand for gasoline are shown to exhibit greater asymmetry in demand responsiveness. These findings provide valuable new evidence to support recent developments in the behavioral litera- ture and also broaden our understanding of the factors affecting temporal and geographic heterogeneity in the price responsiveness of gasoline demand and the influence of price volatility on overall gasoline consumption.

The Stanford Center at Peking University (SCPKU), the Center on Democracy, Development and the Rule of Law (CDDRL), and the APARC China Program jointly hosted a workshop on China’s Belt and Road Initiative (BRI) in early March. The workshop, held on March 2 and 3, welcomed researchers from around the world with expertise in the Initiative. Unfortunately, because of the rapidly developing health emergency related to the coronavirus, participants from not only China, but also Japan, were prevented from attending. As described by Professor Jean Oi, founding director of SCPKU and the China Program, and Professor Francis Fukuyama, director of CDDRL and the Ford Dorsey Master's in International Policy, who co-chaired the workshop, the meeting aimed to provide a global perspective on the BRI, consolidate knowledge on this opaque topic, and determine the best method and resources for future research.  

The workshop began with presentations from several of the invited guests. Dr. Atif Ansar from the University of Oxford’s Saïd Business School kicked off the first day by describing not only the tremendous opportunity that the BRI presents to developing economies, but also the serious pitfalls that often accompany colossal infrastructure projects. Pointing out the poor returns on investment of mega infrastructure projects, Ansar examined the frequest cost and schedule overruns, random disasters, and environmental degradation that outweigh the minimal benefits that they generally yield. China’s own track record from domestic infrastructure projects does little to mitigate fear of these risks, Ansar claimed. In response, he urged professional management of BRI investments, institutional reforms, and intensified deployment of technology in BRI projects. Dr. Ansar was followed by Dr. Xue Gong of the S. Rajaratnam School of International Studies, Nanyang Technological University, Singapore. Dr. Gong’s analysis centered on the extent to which China’s geopolitical motivations influenced its outward foreign direct investments (OFDI). Although her research was still in the early stages, her empirical analysis of China’s OFDI inflows into fifty BRI recipient countries from 2007-2018 nevertheless revealed that geopolitical factors often outweigh economic factors when it comes to China’s OFDI destinations.

Amit Bhandari of Gateway House: Indian Council on Global Relations presents his research at the Belt and Road Workshop.
Participants then heard presentations from Amit Bhandari of Gateway House: Indian Council on Global Relations and Professor Cheng-Chwee Kuik of the National University of Malaysia. Mr. Bhandari’s talk focused on Chinese investments in India’s six neighboring countries, which tend to center more on energy rather than connectivity projects. He first found that the investments are generally not economical for the host countries because they come with high costs and high interest rates. Secondly, he argued that these projects often lacked a clear economic rationale, appearing instead to embed a geopolitical logic not always friendly to India. Professor Kuik, by contrast, provided a counterexample in his analysis of BRI projects in Southeast Asia. He described how, in Southeast Asia, host countries’ reception of the BRI has varied substantially; and how various stakeholders, including states, sub-states and other entities, have used their leverage to shape outcomes more or less favorable to themselves. Kuik’s analysis injected complexity into the often black-and-white characterizations of the BRI. He highlighted the multidimensional dynamics that play out among local and state-level players in pursuit of their goals, and in the process of BRI implementation.

Professor Curtis J. Milhaupt and Scholar-in-Residence Jeffrey Ball, both at Stanford Law School, followed with individual presentations on the role of State-Owned Enterprises (SOEs) in the BRI and the emissions impact of the BRI on climate change, respectively. Professor Milhaupt  characterized Chinese SOEs as both geopolitical and commercial actors, simultaneously charged with implementing Party policies and attaining corporate profits. Chinese SOEs are major undertakers of significant overseas BRI projects, acting not only as builders but also as investors, partners, and operators. This situation, Milhaupt asserted, carries significant risks for SOEs because these megaprojects often provide dismal returns, have high default rates, and can trigger political backlash in their localities. Milhaupt highlighted the importance of gathering firm-level data on businesses actually engaged in BRI projects to better infer geostrategic, financial, or other motivations. Jeffrey Ball turned the discussion to carbon emissions from BRI projects and presented preliminary findings from his four-country case studies. He concluded that, on aggregate, the emissions impact of the BRI is still “more brown than green.” Twenty-eight percent of global carbon emissions may be accounted for by BRI projects, Ball asserted, underscoring the importance of the BRI to the future of global climate change.

The day concluded with presentations by  Michael Bennon, Managing Director at the Stanford Global Projects Center, and Professor David M. Lampton, Oksenberg-Rohlen Fellow at the Freeman Spogli Institute for International Studies. Bennon first presented findings from two empirical case studies of BRI projects and then went on to describe how the BRI is now practically the “only game in town” for infrastructure funding for developing countries. Lengthy environmental review processes at Western multilateral banks have turned the World Bank, for example, from a lending bank into a “knowledge bank,” he argued. He also highlighted that, in general, economic returns on BRI projects for China are very poor, even though recipient countries may accrue macroeconomic benefits from these projects. Finally, Professor Lampton turned the discussion back to Southeast Asia, where China is currently undertaking massive cross-border high-speed rail projects through eight ASEAN countries. He described how each host country had varying capacity to negotiate against its giant neighbor, and how the sequential implementation of these cross-border rail projects also had varying impacts on the negotiating positions of these host countries. BRI played out differently in each country, in other words, eliciting different reactions, push-backs and negotiated terms.

The second day of the workshop was dedicated to working toward a collaborative approach to future BRI research. The group discussed the key gaps in the existing research, including how to know what China’s true intentions are, how to measure those intentions, who the main players and their interests in both China and the host countries are, and even what the BRI is, exactly. Some cautioned that high-profile projects may not be representative of the whole. Participants brainstormed about existing and future sources of data, and stressed the importance of diversifying studies and seeking empirical evidence.

The recent shift in the United States from coal to natural gas as a primary feedstock for the production of electric power has reduced the intensity of sectoral carbon dioxide emissions, but—due to gaps in monitoring—its downstream pollution-related effects have been less well understood. Here, I analyse old units that have been taken offline and new units that have come online to empirically link technology switches to observed aerosol and ozone changes and subsequent impacts on human health, crop yields and regional climate. Between 2005 and 2016 in the continental United States, decommissioning of a coal-fired unit was associated with reduced nearby pollution concentrations and subsequent reductions in mortality and increases in crop yield. In total during this period, the shutdown of coal-fired units saved an estimated 26,610 (5%–95% confidence intervals (CI), 2,725–49,680) lives and 570 million (249–878 million) bushels of corn, soybeans and wheat in their immediate vicinities; these estimates increase when pollution transport-related spillovers are included. Changes in primary and secondary aerosol burdens also altered regional atmospheric reflectivity, raising the average top of atmosphere instantaneous radiative forcing by 0.50 W m−2. Although there are considerable benefits of decommissioning older coal-fired units, the newer natural gas and coal-fired units that have supplanted them are not entirely benign.
