This study empirically investigates how two types of airport charges (per-passenger and per-flight) differentially affect airfares, service quality (flight frequency), and welfare. A structural model endogenizing airfares and flight frequency is estimated with data on Japanese domestic routes...

This study provides the first empirical test of strategic interactions in the pricing decisions of regulated utilities. Since publicly owned water utilities in Sweden are governed by a cost-of-service regulation, prices in neighboring municipalities should not affect the own price other than...

In this paper we study the effect of the terms of access to an incumbent's infrastructure on an entrant's incentives to build its own infrastructure. Setting a high level of access (e.g., a resale arrangement), which requires relatively small up-front investment for entry, accelerates market...

Utilities regulation attempts to attenuate the effects of market failure. Contemporary systems of regulation are generally either rate of return or price cap (RPI-X) systems. This paper addresses the issue of the levels of excess returns and risk inherent in investment in the equity of regulated...

This paper examines problems of entry, exit and competition in Ukrainian product markets. It finds that Ukraine still has too little of all three, and that exit mechanisms, in particular, function poorly. Since impediments to entry and exit are largely the product of excessive and ill...

Regulations of product markets serve legitimate objectives but, when ill-designed, can impose unnecessary restrictions on competition, and therefore on business dynamism, productivity and ultimately well-being. A recent update of the OECD’s Product Market Regulation indicator for Costa Rica...
