This survey of the theoretical and empirical literature on alternative policies to promote new fiber-based communications infrastructures addresses (i) various kinds of ex ante sector-specific regulations, (ii) deregulatory approaches based on effective competition law implementation and competitive market structures including co-investment models, and (iii) public subsidies to cover non-profitable (white) areas. The authors identify significant research gaps and present a generic framework for policy recommendations. Public subsidies emerge as the dominant policy alternative in white areas, whereas access regulations can be the preferred policy in white or gray areas, where only monopoly structure or co-investment models lead to private investment. Deregulatory policies might be preferable in gray areas, provided there is sufficient pressure from competitive outside options and if competition law is strong. Finally, deregulatory policies including soft regulation are the dominant policy in black areas, where several independent infrastructure operators exist.

We empirically estimate the effects of regulated access prices and firms’ multinational status on firm performance by using firm, corporate group, and country level information for the European broadband market between 2002 and 2010. Three measures of firm performance are used, namely: market share, revenue and productivity. Special attention is paid to differences in the impact on the performance measures depending on a firm’s position as either a market incumbent or entrant. We find that while access prices have a negative effect on entrants’ market share and revenue, the effect on incumbents’ market share, revenue and productivity is positive. Further, we find that multinational entrants perform better than national entrants in terms of their market share but worse in terms of their revenue and productivity. The opposite is true of incumbent multinationals which perform better than nationals in terms of their revenue and productivity but worse in terms of their market share. This confirms that a firm’s multinational status has a significant impact on its performance, and that this impact differs for incumbents and entrants. Finally, when evaluating the impact of access prices on firm performance at the mean performance of national and multinational firms, we find that the impact of access prices is lower for multinational than for national firms.

This paper surveys the economics literature on payment cards, focusing on the role of interchange fees, merchant internalization, surcharging and two-sided markets. The paper aims to integrate a wide range of theoretical papers with the relevant empirical research and important policy questions. We address not only the accomplishments of the research so far, but also the most important limitations in the existing theory and gaps where future research should be directed. Drawing on the insights developed, we provide a detailed evaluation of different policy options.

Analysts of air travel markets, which include antitrust authorities, are interested in understanding the extent to which the presence of intermediate stop(s) products influences the pricing of nonstop products. This paper uses a structural econometric model to investigate the potential pricing interdependence between these two product types in domestic air travel markets. Counterfactual experiments using the estimated model suggest that in many (but far from a majority) markets the current prices of nonstop products are at least 5% lower than they would otherwise be owing to the presence of intermediate-stop(s) products.
