Economists have long discussed the correlation between the quality of competition policies and a country's productivity growth. It is, however, very difficult to prove this connection, to determine its extent or to quantify it. Commissioned by the European Commission, a team of international...

This paper evaluates changes in fuel procurement practices by coal- and gas-fired power plants in the United States following state-level legislation that ended cost-of-service regulation of electricity generation. I find that deregulated plants substantially reduce the price paid for coal (but...

We use a sample of 167 mergers during the period 1990-2002 involving 544 firms either as merging firms or competitors. We contrast a measure of the merger’s profitability based on event studies with one based on accounting data. We find positive and significant correlations between them when...

This paper applies a novel methodology to a unique dataset of large concentrations during the period 1990-2002 to assess merger control’s effectiveness. By using data gathered from several sources and employing different evaluation techniques, we analyze the economic effects of the European...

In this paper, we develop a market screening model to detect inconstancies in price changes. Although there is a long history of industrial organization research of collusion, price setting behavior, and conduct - a robust model to detect structural changes in market structure was missing so...

Electricity distribution network is a prime example of a natural local monopoly. In many countries, electricity distribution is regulated by the government. Many regulators apply frontier estimation techniques such as data envelopment analysis (DEA) or stochastic frontier analysis (SFA) as an...

Regulatory reform efforts in a broad range of industries have resulted in increased importance of competitive forces as a means to allocate resources and improve economic efficiency. A number of indicators suggest that such forces have been stronger in the United States than in most other OECD...

In this study, the interaction between the competition-cooperation nexus and regulation in retail payment systems is analysed by applying the main lessons from the theory of network industries. This is justifiable on the grounds that the payment systems industry inherently has many...
