Xi He’s research focuses on understanding how agricultural and food policies are formed and how they affect food security and public health at global, national, regional, and micro levels. Her current research focuses on three areas: 1) the political and economic determinants of agricultural trade policies, such as non-tariff barriers, and how these policies shape the multilateral and bilateral trade system, and 2) outreach and extension work on the evolution of China’s agricultural import demand and how that shapes global trade patterns; and 3) how climate change affects global food trade, food insecurity, and nutrition in developing countries.

Expertise

  • Agricultural trade policy analysis
  • Food and health economics

Education

  • Ph.D., Agricultural and Resource Economics, University of Connecticut, 2019
  •  M.A., Economics, Beihang University, 2014
  •  B.A., Economics, Beihang University, 2011

I have multiple ongoing projects in agricultural trade and food policy analysis.

The first line of projects assesses the impacts of agricultural trade policies, including the impacts of regional trade agreements on countries’ use of non-tariff measures and the impacts of non-tariff measures on import evasion in agriculture.

The second line of projects utilizes partial equilibrium and general-equilibrium models to analyze the impacts of agricultural and food policies. An example project is that we calibrate the CARD International Agricultural Commodity Market model using 2019/20 marketing year crop data and 2020 calendar year livestock and biofuel data to project China’s agricultural imports under six scenarios.

The third line of projects explores how climate change affects food trade and food insecurity in developing countries, particularly in Africa.
