Big-box retail stores arriving from foreign countries have transformed the way Mexican households shop for goods, sparking a “supermarket revolution”. Traditionally, consumers in developing countries have shopped at street markets and small, independent stores. However, consumers have switched to shopping at foreign retailers, who offer a larger variety of products at cheaper prices. Despite concerns that foreign retailers might adversely affect local employment and household incomes, our evidence shows that allowing them to operate their businesses in Mexico has generated substantial welfare gains for households across the income spectrum by lowering the cost of living, while having limited impacts on total employment, incomes, and local businesses closing.
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.
