"Professor Zhang is one of the UC's leading researchers on the economics of
energy and greenhouse gas emissions in China."
— Speaker host Professor Charles Kolstad

Clustering of wind power generation capacity causes both positive and negative externalities. Wind energy investors dynamically and strategically respond to the agglomeration. In order to estimate the agglomeration effect, I develop a fully dynamic model that incorporates the strategic interactions of wind farms. The econometric model is estimated in two steps: the first step flexibly estimates the policy functions and state transitions, and the remaining structural parameters are estimated in the second step. The wind power development in China is used as the empirical case. The empirical results show evidence of economies of scale resulted from the clustered projects by the same owner. However, the grid congestion effect and the scarcity of available land to develop wind farms decrease profits for wind power firms.

Junjie Zhang is an assistant professor of environmental economics in the School of International Relations and Pacific Studies at the University of California, San Diego. He completed his PhD in environmental and resource economics at Duke University in 2008. He also holds an MS and a BS in environmental engineering from Tsinghua University, and a BA in environmental economics and management from Renmin University in China. Professor Zhang's research centers on empirical issues in environmental and resource economics. His research topics cover climate change, water resources, and fisheries. He is particularly interested in an interdisciplinary approach that involves both social sciences and natural sciences to deal with environmental problems having policy relevance.

NOTE: Research colloquia are hosted by Bren faculty members and are generally high-level talks about research in a particular area of environmental science and management.
