Do European car manufacturers make exclusive dealing contracts with their retailers to keep out new, smaller suppliers (mainly from Asia) and in turn, hurt competition? The manufacturing industry could collectively maintain an exclusive dealing system through a block exemption regulation, which would require exclusive dealing through manufacturers’ retailers. Our research shows that if these exclusive contracts were banned, consumers would benefit from allowing dealerships to have more than one supplier and consequently, more brands of cars in stock. However, consumers would not benefit much through increased price competition, in contrast to what is commonly believed.
