We assess how firms' incentives to operate and invest in energy storage depend on the market structure. For this purpose, we characterize equilibrium outcomes allowing for power and/or production, as well vertical integration between production. Market reduces overall efficiency through two channels: It induces an inefficient use of facilities, it distorts investment incentives. The worst outco...

Abstract The political news media play an important role in the successful working of democratic societies. In order to fulfill this role, a sufficient level journalistic quality is required. Most Western societies rely on market as means assure quality. This implies regulation sector by competition law, which may take different attitudes towards power. While it undisputed that some aspects bet...

I present a model where firms and workers set wages above the market-clearing level. Unemployment is thus generated by their exercise of market power. Because both the labor and product markets are imperfectly competitive, market power in the labor market interacts with market power in the product market. This interaction sheds new light on the effects of policy interventions on unemployment an...

Previous studies of the cable television industry have focused on the effects of deregulation and competition on cable service prices. These studies use either the "most popular" tier or the "lowest-priced" tier when comparing prices of different cable systems. However, these tiers often represent a different type of cable service so that previous empirical results based on the assumption that ...

Market power refers to the ability of sellers or buyers to exert a perceptible control over market outcomes that enables them to attain higher individual welfare levels than they would achieve under competitive market conditions. In traditional microeconomic analysis, market power is deened in terms of price and quantity decisions. Market power is said to exist when sellers or buyers have power...

Recent theoretical work has shown firms have market power when hiring workers that is independent of the labor market. However, current techniques for measuring market power are unable to separate the firm determinants of market power from the market determinants. This paper proposes a new method for measuring monopsony that yields a firm-specific measurement, which I apply to the Indonesian ma...

We investigate the competitive effects of the merger between Delta Air Lines and Northwest Airlines (2009) in the domestic U.S. airline industry. Applying fixed effects regression models we find that the transaction led to short term price increases of about 11 percent on overlapping routes and about 10 percent on routes which experienced a merger-induced switch of the operating carrier. Over a...

This thesis consists of five self-contained papers on factor demand and market power. The main objective of Paper [I] is to analyze potential effects on the Swedish forest sector of a continuing rise in the use of forest resources as a fuel in energy generation. The background to the problem can be found in the commitments Sweden has made concerning energy policy. Two such commitments are the p...
