This paper studies shopping hour decisions by retail chains and independent competitors. We use a Salop-type model where retailers compete in prices and shopping hours. Our results depend significantly on efficiency differences between retail chain and independent retailer. If the efficiency...

Consider a government that auctions a franchise for, e.g., an airport, telecommunication network, or utility. Consider an 'incumbent bidder' that owns a complement or substitute. With an auction on the transfer (i.e. payment) to the government, the incumbent is advantaged.If the government...

Consider a government tendering a facility, such as an airport or utility, where one bidder owns a competing facility. With a standard auction, this existing operator bids above the auctioned facility's expected profit, as winning means being a monopolist instead of a duopolist. This auction...

We examine how vertical separation affects the lobbying activities for the access charge of essential facilities. First, when investigating a model where the number of new entrants is fixed, we find that vertical separation either increases or decreases the access charge, and that this depends...

We examine incentives of bottleneck facility holders to manipulate access charge accounting in free entry downstream markets. We consider the situation wherein one firm holds an upstream bottleneck facility and new entrants use it at the regulated price (access fee) to provide final products....

We propose a two-sided model with two competing Internet platforms, and a continuum of Content Providers (CPs). We study the effect of a net neutrality regulation on capacity investments in the market for Internet access, and on innovation in the market for content. Under the alternative...

The relationship between technical progress and price competition is a controversial issue in economics. This paper highlights the fact that investment in technical progress is an authentic type of competition which benefits the consumers rather than the industry. This type of competition exists...

Typically, incumbent providers enjoy a demand-side advantage over any entrant. However, market entrants may enjoy a supply-side advantage in costs over the incumbent, since they are more efficient or operate on innovative technologies, such as the voice of internet protocol (VoIP) telephony....

In this paper, we examine welfare implications of switching from a neutrality regime to a network management regime. While in the former a network provider or an integrated ISP should transmit data with a-bit-is-a-bit principle, in the latter it is allowed to differentiate its connection quality...
