Prices and price risk management along coffee chains Susan Newman “Challenges and Prospects for Commodity Markets in the Global Economy” A Workshop in Memory of Alfred Maizels 19th September 2008 SOAS, University of London
Background Policy shifts and the debate around commodity issues • Breakdown of Bretton Woods • Collapse of multilateral price stabilisation schemes for commodities • Liberalisation of agricultural markets in agro-commodity exporting LDCs under SAPs • Emphasis on private risk management (PRM) strategies for the stabilisation of incomes Theoretical justifications for liberalisation and PRM-strategies • Neoclassical economics: • on derivatives markets: • Efficient Market Hypothesis • Arrow-Debrau • Implicit theory of price determination according to supply and demand. • on commodity markets: • Horizontal conception of the market • Competitive markets • Prices governed by the interaction of supply and demand • Assumed relationship between the derivatives and physical markets for commodities
Financialisation of commodity markets • Financialisation can be broadly defined as “the increasing role of financial motives, financial markets, financial actors and financial institutions in the operation of the domestic and international economies” (Epstein 2005, p3). • Dimensions of financialisation in the international commodity systems: • Increasing portfolio investment in commodities as an asset class • Increase in the volume of derivatives trading by physical traders for hedging as well as non-hedging purposes • Changes in the distribution of income along commodity chains that depends upon the ways in which heterogeneous chain actors engage with futures markets

An investigation of prices and price risk management along coffee chains • How do the prevailing market structures mediate the processes of price transmission along coffee chains? • To what extent are the structures of different segments along coffee chains shaped by the processes of price risk management? • What are the implications of this restructuring of coffee markets in terms of income generation of different market actors along the chain? • What are the implications of this restructuring on the sustainability of the coffee system?
