Recent changes to the common agricultural policy (CAP) saw a shift to greater market orientation for the EU dairy industry. Given this reorientation, the volatility of EU dairy commodity prices has sharply increased, creating the need to develop proper risk management tools to protect farmers' income and to ensure stable prices for processors and consumers. In addition, there is a perceived threat that these commodities may be replaced by cheaper substitutes, such as palm oil, as dairy commodity prices become more volatile. Global production of palm oil almost doubled over the last decade while butter production remained relatively flat. Palm oil also serves as a feedstock for biodiesel production, thus establishing a new link between agricultural commodities and crude oil. Price and volatility transmission effects between EU and World butter prices, as well as between butter, palm oil and crude oil prices, before and after the Luxembourg agreement, are analysed. Vector autoregression (VAR) models are applied to capture price transmission effects between these markets. These are combined with a multivariate GARCH model to account for potential volatility transmission. Results indicate strong price and volatility transmission effects between EU and World butter prices. EU butter shocks further spillover to palm oil volatility. In addition, there is evidence that oil prices spillover to World butter prices and World butter volatility.

Purpose -The purpose of this paper is to analyze how the German, Irish and average EU farm gate milk prices have changed after the common agricultural policy (CAP) reform in 2003. In addition the dynamics of these prices are compared to a US farm gate price. Design/methodology/approach -These milk price time series are divided into two time periods, pre and post the CAP 2003 reform, and decomposed into their trend, seasonal and cyclical components. For the decomposition a state space model is used following the approach of Harvey (1989). Findings -The results show that the dynamics of the EU, German and Irish series converged after the CAP 2003 reform were implemented and that a three-year cycle is underlying the European milk prices which is comparable with the cycle length of the US milk price. In addition it is shown that most of the observed price variation in recent times is attributed to the cyclical component.Research limitations/implications -The division of the milk price time series into periods pre and post the CAP 2003 reform is somewhat subjective because not all measures were immediately applied after the reform. It is also possible that other factors may have contributed to the changed dynamics which have been observed. In addition this leads to a short data sample. Practical implications -The results show that policy makers should consider counter cyclical policy measures given the importance of the cyclical component. Also most models used to evaluate policies do not account for cycles which may lead to wrong conclusions. In addition farmer should be aware of the cyclical nature of milk prices as they budget and plan for the future. Originality/value -No previous decomposition studies of European milk prices exist.

Price and volatility transmission effects between European Union (EU) and World skimmed milk powder (SMP) prices, as well as those between both SMP series, soybeans and crude oil prices from 2004 to 2014 were analysed using a vector error correction model combined with a multivariate GARCH model. The results show significant transmission effects between EU and World SMP prices, but no significant transmission effects from soybeans or crude oil to either of the SMP prices. For policymakers and modellers, these results indicate the need to consider World SMP prices when considering EU prices. On the other hand, the finding of no transmission effects from soybean to SMP prices reduces the opportunity for a successful cross-hedging for dairy commodities using well-established soybean derivative markets.
