We analyse optimal environmental policies in a market that is vertically differentiated in terms of the energy efficiency of products. Considering energy taxes, subsidies to firms for investment in more eco-friendly products, and product standards, we are particularly interested in how...

We study the incentives for hospitals to provide quality and expend cost-reducing effort when their budgets are soft, i.e., the payer may cover deficits or confiscate surpluses. The basic set up is a Hotelling model with two hospitals that differ in location and face demand uncertainty, where...

The Pennsylvania Liquor Control Board administers the purchase and sale of wine and spirits and is mandated to charge a uniform 30% markup on all products. We use an estimated discrete choice model of demand for spirits, together with information on wholesale prices, to assess the implications...

This paper investigates telecommunication operator investment in broadband infrastructure after local deregulation of the wholesale broadband access market. Using a panel dataset covering all 5,598 exchange areas in the United Kingdom, we exploit regional differences in deregulation following a...

We present an analysis of the share of public ownership in the product market in the OECD countries from 1974 to 2007. Despite much has been said on the broad topic of reforms and regulation, a sector-specific insight is missing. We replicate the analysis of Galasso (2014) by sector of activity...

We study how net neutrality regulations affect a high-bandwidth content provider’s (CP) investment incentives in quality of services (QoS). We find that the effects crucially depend on network capacity levels. With limited capacity, as in mobile networks, prioritized delivery services are...

Based on an idiosyncratic reading of the literature I propose intermediate (rather than tight or soft) regulation for balancing investment incentives with allocative efficiency and competition objectives. Intermediate regulation is compatible with incentive regulation and helps lengthening the...

The goal of this paper is to bring some unity to the theoretical side of the debate on internalization of airport congestion by showing that all the literature’s theoretical results can be derived within one simple and unified framework. The analysis starts by replicating the results of...

The paper aims at assessing discrete complementarities in innovation policies in the context of the Brazilian industry in 2003. The paper considers the approach advanced by Mohnen and and Röller [European Economic Review, 2005] that focuses on supermodularity and submodularity tests for...

Recent advances in telecommunications, particularly using fibre technologies, permit many services based on data-processing to be performed anywhere in the world. They thus become tradable and subject to the laws of comparative advantage. A good example is data-processing within large...
