We review the recent empirical research concerning market power on the Nordic wholesale market for electricity, Nord Pool. There is no evidence of blatant and systematic exploitation of system level market power on Nord Pool. However, generation companies seem from time to time able to take...

This paper quantifies the degree of market power in the German wholesale electricity market. A fundamental model is used to derive competitive marginal cost estimators which are compared with observed electricity prices. Marginal costs are calculated focusing on market fundamentals such as plant...

This paper shows that generators exercised increasing market power in the England and Wales wholesale electricity market in the second half of the 1990s despite declining market concentration. It examines whether this was consistent with static, non-cooperative oligopoly models, which are widely...

In the process of regulatory reform in the electric power industry, the mitigation of market power is one of the basic problems regulators have to deal with. We use experimental data to study the sources of market power with supply function competition, akin to the competition in wholesale...

We test how bank market power influences technical change and resource allocation of informationally opaque firms. We use a dataset with approximately 700,000 firm-year observations of German small and medium-sized enterprises (SME) to identify the effect of bank market power using the...

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...

This paper applies several extensions of Hall's (1988) methodology to analyse imperfections in both the product and the labour market for firms in the Belgian manufacturing industry over the period 1988-1995. We investigate (1) the heterogeneity in mark-up and bargaining power parameters among...

This paper uses representative firm level panel data of 1,701 Bulgarian and 2,047 Romanian manufacturing firms to estimate market power (i.e. price-cost margins) and to analyze how these are affected by privatization and increased competitive pressure. In contrast to earlier work that analyzes...

In this paper, we analyze the effects of trade, concentration and ownership on the pricing behavior of firms in two transition countries, Bulgaria and Romania. We use an extensive dataset of more than 3000 firms and sector level infirmation to estimate the effects of these three factors on the...

This paper estimates how anti-dumping (AD) protection affects the market power of firms. To this end, we use a rich panel data set of 1,666 EU producers that were involved in AD cases initiated in 1996 to estimate markups of price over marginal cost. Our findings indicate that markups in most...
