An increasing body of empirical evidence is documenting trends toward rising concentration, profits, and markups in many industries around the world since the 1980s. Two major criticisms of these studies is that concentration and market shares are poorly measured at the national industry level...

Worldwide, the overwhelming majority of large horizontal mergers are cleared by antitrust authorities unconditionally. The presumption seems to be that efficiencies from these mergers are sizeable. We calculate the compensating efficiencies that would prevent a merger from harming consumers for...

In a two-country reciprocal dumping model, with one country unionized, we analyze how wage setting and firm location are influenced by trade liberalization. We show that trade liberalization can induce FDI, which is at odds with conventional theoretical wisdom and cannot happen in a...

We examine how a downstream merger affects input prices and, in turn, the profitability of a such a merger under Cournot competition with differentiated products. Input suppliers can be interpreted as ordinary upstream firms, or trade unions organising workers. If the input suppliers are...

We consider a model of a TV oligopoly where TV channels transmit advertising and viewers dislike such commercials. We show that advertisers make a lower profit the larger the number of TV channels. If TV channels are sufficiently close substitutes, there will be underprovision of advertising...

The TV industry is a two-sided market where both advertisers and viewers buy access to the programs offered by competing TV channels. Under the current market structure advertising prices are typically set by TV channels while viewer prices are set by distributors (e.g. cable operators). The...

This paper studies the interaction between public and private health care provision in a National Health Service (NHS), with free public care and costly private care. The health authority decides whether or not to allow private provision and sets the public sector remuneration. The physicians...

The purpose of this article is to analyze how competitive forces may influence the way media firms like TV channels raise revenue. A media firm can either be financed by advertising revenue, by direct payment from the viewers (or the readers, if we consider newspapers), or by both. We show that...

We analyze strategic interactions between two competing distributors of an independent TV channel. Consistent with most of the relevant markets, we assume that the distributors set end-user prices while the TV channel sets advertising prices. Within this framework we show that the distributors...

In this paper we investigate the relationship between news sources and media firms. Although empirically important, this channel for supply-driven media bias has not previously been analyzed in economics literature. We model the relationship as an informal contract based on trust and punishment,...
