My research lies at the intersection of environmental and energy economics, urban and real estate economics, and development economics. I am interested in the efficacy of policy tools for climate mitigation, the costs and effectiveness of housing-affordability policies, and the effects of climate change and adaptation in cities. 我的研究处于环境与能源经济学、城市与房地产经济学以及发展经济学的交汇处。我关注政策工具在气候减缓中的有效性、住房可负担性政策的成本与成效,以及气候变化与适应在城市中的影响。

This thread examines how incentive-based environmental regulation — rather than conventional command-and-control — influences firms' carbon emissions, air pollution, and the transition to cleaner energy.这条主线考察基于激励的环境监管(相对于传统的"命令—控制"式监管)如何影响企业的碳排放、空气污染,以及向清洁能源的转型。
In "Evaluating Power Sector Emissions under Regional Carbon ETS Pilots in China: A View from Space," I use a staggered difference-in-differences design and novel NASA Aura satellite data to show that — contrary to expectations — tradable-performance-standard ETS pilots raised sulfur-dioxide emissions from Chinese coal plants by 5–7% relative to non-ETS facilities, because output subsidies can increase output from cleaner plants.在《从太空评估中国区域碳排放权交易试点下的电力部门排放》中,我采用交错双重差分设计与新型 NASA Aura 卫星数据发现:与预期相反,基于"可交易绩效标准(TPS)"的碳交易试点反而使燃煤电厂的二氧化硫排放相对非试点设施上升了 5–7%——原因在于产出补贴可能提高了较清洁电厂的产量。
Two new projects build on this: (1) how cap-and-trade in Ontario and Quebec, vis-à-vis the federal program, affects local air pollution and manufacturing; and (2) the spillover effects of China's Belt-and-Road energy investments on host countries' air pollution, power reliability, health, and employment. A related project quantifies the learning curve of China's onshore wind sector.在此基础上的两个新项目:(1)安大略与魁北克的限额—交易机制相较联邦机制,对本地空气污染与制造业的影响;(2)中国"一带一路"海外能源投资对东道国空气污染、电力可靠性、健康与就业的溢出效应。相关研究还量化了中国陆上风电行业的学习曲线。
Thread 02主线 02
This thread investigates the distributional consequences of rent regulation. Using nearly two decades of New York City Housing and Vacancy Survey microdata, my 2023 article with H. Jiang and L. Quintero quantifies the rent discounts created by rent stabilization.这条主线研究租金管制的分配后果。我与 H. Jiang、L. Quintero 合作、发表于 2023 年的论文利用纽约市住房与空置调查近二十年的微观数据,量化了租金稳定政策带来的租金折扣。
We find that rent stabilization in NYC is not progressive — it does not give larger discounts to lower-income households — and is associated with large racial inequality, though the racial gap has narrowed since 2011. We estimate total rent subsidies of three to five billion dollars per year.研究发现:纽约市的租金稳定政策并不具累进性——并未向低收入家庭提供更大折扣——且伴随显著的种族不平等,尽管这一差距自 2011 年以来有所缩小。我们估计每年的租金补贴总额约为 30–50 亿美元。
Follow-up work examines specific subgroups — immigrants (Real Estate Economics, 2025) and elderly renters (Urban Studies, 2025). Ongoing projects document, for the first time, owners' non-compliant rent overcharges and their racial disparities; study filtering in affordable-housing supply; and assess how short-term-rental (e.g., Airbnb) regulation affects local housing markets and neighborhood quality of life.后续研究进一步考察了具体人群——移民(《Real Estate Economics》,2025)与老年租户(《Urban Studies》,2025)。在建项目首次系统记录了业主违规"超额收费"行为及其种族差异,研究可负担住房供给中的"过滤"过程,并评估短期租赁(如 Airbnb)监管对本地住房市场与社区生活质量的影响。
Thread 03主线 03
Building on my expertise with satellite data and causal inference, I study how climate change and environmental shocks affect local housing markets and vulnerable populations. A new project examines how climate change interacts with historical housing discrimination — such as redlining — to shape household adaptation outcomes.依托在卫星数据与因果推断方面的专长,我研究气候变化与环境冲击如何影响本地住房市场与脆弱人群。一个新项目考察气候变化如何与历史性的住房歧视(如"红线政策")交互,塑造家庭的适应结果。
My long-term objective is to produce evidence that informs the design of policies capable of addressing climate change while promoting urban sustainability and social inclusion. 我的长期目标,是为政策设计提供证据,使其在应对气候变化的同时,促进城市可持续与社会包容。
