Sub-Saharan Africa's air transport, though low in overall volume when compared to other regions in the world, has experienced significant growth in the last decade, both in international and domestic traffic. The sector, in part because of its relatively small size, still faces the challenges of...

Efficient transport links are critical to enhancing the integration of markets in Southern Africa. This paper assesses the structure of markets, competition, and prices and costs of road transportation between urban hubs in Malawi, Mozambique, South Africa, Zambia, and Zimbabwe. Key findings are...

Rapid urbanization and rising income levels in Southern Africa have increased the consumption of perishable and processed food products. This paper relies primarily on firm-level interview data to assess competition and bottlenecks in transporting time-sensitive perishable products across...

Previous research shows that firms shroud high add-on prices in competitive markets with naive consumers leading to inefficiency. We analyze the effects of regulatory intervention via educating naive consumers on equilibrium prices and welfare. Our model allows firms to shroud, unshroud, or...

This Paper introduces optimal competition: the best form of competition in an industry that a competition authority can achieve (given the information constraint that it cannot observe firms’ efficiency levels). We show that the optimal competition outcome in an industry becomes more...

We study the effects of reputation and competition in a stylized market for experience goods. If interaction is anonymous, such markets perform poorly: sellers are not trustworthy, and buyers do not trust sellers. If sellers are identifiable and can, hence, build a reputation, efficiency...

We examine a Bertrand competition game between two intermediaries offering matching services between two sides of a market. Indirect network externalities arise as the probability of finding one's match with a given intermediary increase with the number of agents of the other side who use the...

For most of the twentieth century, collective bargaining provided the terms on which labour was commonly employed in Britain. However, the quarter century since 1980 has seen the collapse of collectivism as the main way of regulating employment. Our argument is that the tacit settlement between...

This Paper examines competition between a dominant network and a challenging network with third-degree or perfect price-discrimination, allowing for arbitrary configurations of network externalities, as well as horizontal and vertical product differentiation. Domination in the coordination game...
