To respond to client demand at this crucial moment for economic development, the World Bank Group is generating knowledge to better understand the links among competition, growth and shared prosperity, and to develop policies that promote competition. Last week, at a Bank Group event, held jointly with the Organization for Economic Cooperation and Development (OECD), experts and practitioners discussed the growing body of empirical evidence on these matters. Representatives from the WBG’s client countries, in turn, shared how WBG competition policy tools are leveraging their development impact.
Competition in the marketplace matters for economic growth and household welfare for two reasons:
- First, it fosters more productive firms and industries, allowing domestic firms to become more competitive abroad and to export more. A WBG study shows that substantially increasing competition in Tunisia would boost labor productivity growth by 5 percent.
- Second, it protects poorer households from paying too much for consumer goods, and from missing out on the benefits of trade liberalization. In Mexico, lack of competition costs the poorest households 20 percent more than richest households. In Kenya, poverty could fall by 2 percent if competition was more intense in the maize and sugar markets.
Competition is restricted by businesses practices that undermine competitive dynamics. When firms agree to fix prices, empirical evidence reveals that consumers pay on average 49 percent more, and 80 percent more when cartels are strongest. Developing economies are still frequently marked by regulations that restrict the number of firms or limit private investment; rules that increase business risks and facilitate agreements among competitors; and rules that discriminate against certain competitors or affect competitive neutrality. When new retail firms are allowed to enter the market, real household income increases by 6.2 percent.
