China and World Grain Price Volatility Approach

Approach

Solve and simulate a stochastic spatial-temporal equilibrium model

  • f the world market for a generic storable food commodity with

China as the centerpiece, apply it to corn and wheat.

China and World Grain Price Volatility Background

Background

◮ World Food Price Crisis in 2007-8 caught many unprepared ◮ Price of wheat reached a peak of ✩440/ton in March 2008 ◮ Price of corn reached ✩287/ton in June 2008 ◮ FAO estimates chronically hungry rose by 75 million in 2007

China and World Grain Price Volatility Background

◮ China, however, maintained relatively stable domestic prices ◮ Historically, China has been self-sufficient in grains ◮ Achieved through buffer stocks and trade restrictions ◮ Stocks proportionately much larger than rest of the world ◮ Imports and exports a small proportion of China’s production ◮ Pre-2009, wheat-corn imports less than 1% of production

China and World Grain Price Volatility Background

◮ However, Chinese grain production and consumption have

been undergoing major changes in recent years

◮ Rising living standards, increased urbanization have led to

increasing per capita meat consumption

◮ This has led to increased demand for grains and oilseeds ◮ China may account for 40% of global trade over coming

decade

China and World Grain Price Volatility Background

◮ Chinese agricultural support policies have also undergone

major changes in recent years

◮ Starting in 2004, after decades of taxing agricultural

production, China began to subsidize agriculture production

◮ Subsidies reached 9% of value of agricultural output in 2012 ◮ Between 2008-2013, corn-wheat price supports rose 60-70% ◮ Increases have not kept pace with rising production costs ◮ Placed pressure to raise price supports further

SLIDE 11

China and World Grain Price Volatility Background

◮ Chinese government’s 5-year plan for 2011-15 called for

continued increases in support prices

◮ Support levels approaching those of developed countries ◮ Inviting increased WTO scrutiny of Chinese ag policies ◮ China’s domestic prices rising above world levels ◮ This has attracted a surge in imports ◮ U.S. major beneficiary, exports to China tripled 2007-12

China and World Grain Price Volatility China - Questions of Interest

China - Questions of Interest

◮ What will be in impact of

◮ Chinese rising demand for grain ◮ Chinese price support programs ◮ Chinese global market integration

  • n

◮ Chinese imports and exports ◮ Variability of world prices

◮ Is China’s buffer stock policy sustainable? ◮ If not, what happens in the long run?

China and World Grain Price Volatility World Grain Market Model

World Grain Market Model

◮ At OSU, developing a 4-region, 2-commodity stochastic

spatial-temporal equilibrium model of world grain markets

◮ Used to explore impact of trade and price support policies on

global trade and price stability

◮ Model lacks closed-form solution, solved using Chebychev

polynomial projection methods

◮ Experimenting with incomplete polynomial bases, Lobatto

nodal structures, ergodic set methods

SLIDE 16

China and World Grain Price Volatility World Grain Market Model

◮ Work presented today based on subset of larger model ◮ Two regions: China and Rest of World (ROW) ◮ Spatial equilibrium enforced through trade ◮ Competitive storage in ROW enforces intertemporal world

price equilibrium

◮ Government storage in China undertaken by buffer stock

authority at fixed support price

◮ Planned production responds to price expectations

China and World Grain Price Volatility Simulation Experiment Design

Simulation Experiment Design

◮ Factorial design ◮ Autarky versus free trade ◮ Limited and unlimited buffer stock capacity ◮ No, low, high price supports in China ◮ Current and 20% increase in demand in China

China and World Grain Price Volatility Main Findings

Main Findings

◮ A 20% increase in China’s demand for corn will

◮ divert 2.7% of ROW corn production to China ◮ raise world price and volatility by 10%

◮ A 20% increase in China’s demand for wheat will

◮ divert to 2.2% of ROW wheat production to China ◮ raise world price level and volatility by 8% and 6%, respectively 18 / 21

SLIDE 19

China and World Grain Price Volatility Main Findings

Grain Price Support - Baseline Demand

◮ Consider corn price support 6% above historical market

average, baseline demand

◮ If ability to defend unlimited, world price level would rise 8%,

world price volatility would fall 4%, and Chinese corn imports would reach 2.8% of global production

◮ If buffer stock capacity capped, price levels and global trade

would not be affected in long run, but world price volatility would fall 4%

◮ Similar results in the case of wheat

SLIDE 20

China and World Grain Price Volatility Main Findings

Grain Price Support - Increased Demand

◮ Consider corn price support 6% above historical market

average, 20% increase in demand

◮ If ability to defend unlimited, world price level would rise 9%,

Chinese price level would rise 17%, world price volatility would increase 4%, and Chinese corn imports would reach 2.7% of global production

◮ If buffer stock capacity capped, world price level would rise

14%, Chinese price level would rise 26%, world price volatility would increase 4%, and Chinese corn imports would reach 4.1% of global production

◮ Similar results in the case of wheat

China and World Grain Price Volatility Extensions for Future Work

Extensions for Future Work

◮ Explicitly model USA in addition to China and ROW ◮ Allow for distinct release price ◮ Account for private storage in China ◮ Model USA policy interventions more fully ◮ Explore trade restrictions more fully ◮ Model multiple commodities
