Introduction to Environmental Economics (1): Dr. Patrick S. Ward


Environmental Economics

The Master of Environmental Policy Program at Duke Kunshan University uses principles of economics to address real-world environmental policy challenges. It is interdisciplinary in nature, covering economics, green finance, sustainable development, natural resource management, energy transition, agricultural economics, etc.

Professor Introduction

Assistant Professor of Environmental Economics and Policy

Dr. Patrick S. Ward is an assistant professor of environmental economics and policy in the iMEP Program (Master of Environmental Policy) at Duke Kunshan University (DKU) in Kunshan, Jiangsu province, China. Prior to joining the DKU faculty, he was a research fellow in the Environment and Production Technology Division at the International Food Policy Research Institute (IFPRI), first in New Delhi, India and later in Washington, DC.

Dr. Patrick S. Ward’s primary research interests center around sustainable development, with a particular emphasis on developing country agriculture. Having been based in the South Asia region for four years (2012-2016), he has extensive experience conducting research throughout the region (Bangladesh, India, Nepal, and Pakistan). In addition, he has also led or contributed to research on agricultural or development issues in China, Malawi, and Kenya.

Dr. Patrick S. Ward’s current research portfolio includes projects on agricultural risk management (including insurance and other financial products as well as stress-tolerant staple crop cultivars), soil fertility management and soil conservation, inclusive development of rural agricultural machinery markets, and water resource management. He is especially interested in how insights from behavioral economics and cognitive psychology can be used to inform policies and interventions to address environmental and natural resource management challenges.

Dr. Patrick S. Ward hold a Ph.D. in Agricultural Economics with a specialization in International Development from Purdue University (USA). Prior to joining IFPRI, he spent a short period of time as a visiting researcher with the International Center for Climate Governance (ICCG) in Venice, Italy.

iMEP Students' Perspectives

Suzanne, Class of 2021

“This research opportunity is one of the most exciting highlights of my iMEP journey. We know that air pollution causes cardio-pulmonary diseases, but would people change their travel behavior on air polluted days to avoid these health risks? In Prof. Patrick’s research group, we are designing a discrete choice experiment to understand exactly that. Through this research, we explore the unique intersections of environmental policies, behavioral choices, and health valuation. I’ve gained great insight on the scientific method from Prof. Patrick’s diligent guidance and expert advice. The research team’s brainstorming, iteration, and conducive discussion brings a ton of energy and fresh perspectives every week!”

Han, Class of 2021

“Patrick is one of the best professors I've met at IMEP. I took three of his courses: Environmental Policy Analysis, Practicum, and Econ II. He did a fantastic job of bringing development economics to life. When I had questions, he answered all of them very patiently, and was always quick to reply during the pandemic (and with a 12hrs time difference).  Patrick is also a great mentor. His breadth of knowledge really inspired me and I thoroughly enjoy working with him.”

Courses at iMEP

Economics Boot camp

This short course provides a refresher of introductory microeconomics and an overview of intermediate microeconomics, with an emphasis on topics that are pertinent to the analysis of environmental issues (e.g., market failures, externalities, common pool and open access resources, and the implications of policy interventions)

PUBPOL 631K: Research Methods for Environmental Sciences

This graduate level course focuses on imparting a critical perspective of, and an empirical familiarity with, the range of methods available to researchers in the environmental sciences, including both health sciences and social sciences. Topics covered include quantitative and qualitative methods, experimental and quasi-experimental research designs in both the health and social sciences, sampling and sample size determination, survey design and implementation, and the process of publishing academic research.

PUBPOL 871K: Environmental Policy Analysis

This graduate level, professional course provides tools for thinking about, conducting, and communicating analysis of environmental policies. Many of the concepts and tools are discussed are widely applicable to various types of policy settings, but the focus in this course will be explicitly policy problems related to the environment. The class contains a mix of conceptual or theoretical foundations related to the process of policy analysis and policymaking, as well as practical tools and applications that will be useful in the actual structuring and conducting of environmental policy analysis.

PUBPOL 872K: Environmental Economics and Policy Practicum

This graduate level, professional course gives students an opportunity to apply the skills they acquired in previous courses (environmental policy analysis, environmental economics, statistics and program evaluation, etc.) in a practical consulting experience in research and policy analysis. In addition to the client-based projects, semi-weekly course meetings provide students with a deeper and more comprehensive grounding in economic policy analysis, specifically cost-benefit analysis (CBA).

ENVIRON 806K: Environmental Economics II

This graduate level course examines environmental issues in developing countries, including those pertaining to both indoor and outdoor air pollution, but also the management of natural resources such as land, water, and forests in rural areas in developing countries. The focus is on empirical studies that attempt to quantify the impact of human behavior on environmental outcomes or the impact of changing environmental conditions on human and developmental outcomes.
