Trade Liberalization and Mergers in the North American Malting Industry Derek Brewin, Richard Gray and Giannis Karagiannis November 25 th, 2011 Structure and Performance of Agriculture and Agri‐products Industry (SPAA) Ottawa, Ontario

What are the Welfare Impacts of Mergers with Free Trade? Does this persist with further consolidation?

Some Previous Work Azzam, A., and J. Schroeter Tradeoff between Oligopoly and Efficiency: Beef Packing. AJAE. Fjell, K., and D. Pal Mixed Oligopoly in the Presence of Foreign Firms. CanJEc. Buschena, D.E. and R.S. Gray Trade Liberalization and International Mergers: Barley Malting in North America. RevAgEc

Buschena and Gray MC i = e + c i X i Plant level Marginal Cost p ms (X) = a – bX Demand for Malt Services X i = a – b(X -i ) – e. Optimal X i Cournot 2b + c i

Free Trade Plant Marginal Cost – unchanged. Market demand now for Canada and U.S. Total quantity in market increases

Merger Plant Marginal Cost – assumed unchanged, but merged plants set MC of all plants equal – decreases total cost Price Behaviour – increases own firm pricing power – decreases number of firms – price of malting services increase as does malt – barley prices fall

Buschena and Gray

4 Canadian, 7 U.S. malting firms become 4 Can/US mergers and 3 US independents. Free Trade increased Competition Merging decreased total costs – but lowers welfare to barley suppliers and malt users Total welfare impacts positive – free trade gains and cost savings are greater than barley and malt losses to market power

What Happened? Total Q

What Happened? Trade

What Happened? Barley

Sensitivity to Market Power Assumptions Changes to Buschena and Gray. Using pure Cournot current plants had negative slope to cost curves We check for ‘less’ market power effects X i = a – b(X -i ) – e θ = change in total X -i (2+θ)b + c i expected by change X θ = 0, Cournot; θ =-1 Competitive

What Happened? Plants Simulated Firm Level Effects of the Free Trade Agreement and Mergers (θ = -0.1). Sources: pre-CUSTA: Buschena and Gray; current size: First Key, Marginal Cost Authors

What Happened? Welfare θ =-0.1

What Happened? Welfare θ =-0.9

Conclusions/Implications Recent mergers have not offset gains from trade Mergers have redistributed gains from trade back to Malting firms Seed work on Malting Firm bargain with Brewer and Spatial effects of Barley supply Price/cost data?
