1 EU Biofuel policy impact on price fluctuations David Laborde July 2014

2 Biofuels and Price stability: Overview A demand effect: Short term: Surprise effect role on inventories. Should disappear Long term: effect Link to energy markets on the demand side ( more or less price stability?) Current effect: the role of mandatory policies (G20). Agricultural demand becomes more inelastic Supply response: Shift in supply structure (commodities x countries) Feedback via energy markets (diversification) Investments and R&D: Specialized vs generics Risk linked to increase crop specialization (lack of rotation) But keep in mind that prices, and price transmissions are not fully transmitted (eg. Corn in Africa vs Corn in the US; heterogenous wheat markets) Page 2

3 The Worst: the role of Mandatory Policies An additional Inelastic demand (fixed amount of biofuels, not sensitive to prices) in a system already inelastic: Food demand is inelastic: people need to eat Agricultural supply is inelastic in the short term It takes time to grow crops (intertemporal issue) Factors are scarce (water, land) And in the medium term (R&D) When a (climatic) shock happens: Prices will over-react Other components of demand (mainly Feed) are forced to adapt. Page 3

4 The Past: Impact on inventories Structure of the new demand from 2001 to 2011 Biofuels demand Food/Feed component Quick increase (partially driven by policies) of biofuels during the last 6 years Large share in Marginal Demand of Crops Accelerates Depletion of inventories (or) Reduces the rate of accumulation Palm oil Soybean oil Corn Rapeseed Wheat 0% 50% 100% Page 4

5 (not) Dealing with stocks No room for a rationale expectation multi country CGE Reduced form equation? Are biofuels / Biofuels policies shifting storage behavior? Average stocks as a proportion of production More flexible policy: may lead to a decrease in the ratio between Average stocks and production

9 Introducing a stochastic component in the MIRAGE model Caveats: No storage behavior No expectations No risk aversion or not explicitly Introducing yield shocks. Different cases Normalized and homogenous Historic scenario Monte Carlo approach based on Realistic matrix based on cleaned FAO time series Multivariate normal distribution crops x countries Land allocation taken based on the average yield (without shock) Page 9

11 Scenarios Focus on the EU policy Mandate -> very limited flexibilities (compared to RINs) Both ethanol and biodiesel Baseline: 2020 with biofuels incorporation remains at 2008 level in the EU (full policies implemented in ROW) Scenarios EU NREAP by 2020 without trade liberalization EU NREAP by 2020 with trade liberalization Yield shock
