Central banks often use certain concentration indices in their official reports to determine the degree of intensity of competition, of which the most common are the concentration ratio and the Herfindahl-Hirschman index. It is important to emphasize that when calculating the value of these...

This paper investigates the market structure of Arab GCC banking industry during the years of 1993 to 2002 using the most frequently applied measures of concentration kbank concentration ratio (CRk) and Herfindahl-Hirschman Index (HHI) and evaluates the monopoly power of banks over the ten years...

We find that IPOs issued in more competitive, and more highly leveraged, industries underperform in the three years following their issuance. Both results are economically large, and are robust to numerous controls. We conduct several tests to trace the economic sources of this underperformance....

In this paper we present a general approach and methodology for modelling concentration dynamics on industrial level. The majority of research in this field has usually been focused on estimating adjustment models, where the speed of adjustment of actual level of concentration to the long-run...

A growing body of literature indicates that competition increases bank soundness. Applying an industrial organization based approach to large data sets for European and U.S. banks, we offer new empirical evidence that efficiency plays a key role in the transmission from competition to soundness....

This paper estimates a dynamic, structural model of entry and exit in an oligopolistic industry and uses it to quantify the determinants of market structure and long-run firm values for two U.S. service industries, dentists and chiropractors. Entry costs faced by potential entrants, fixed costs...

Theoretically, cross ownership may mitigate mergers, i.e. market concentrations. Holding a share in a competing firm before the acquisition of another firm, outsider-toehold, is more profitable in some market constellations, due to the positive externality on the outsider (competing) firm when a...

In many industries, firms usually have two choices when expanding into new markets: They can either build a new plant (greenfield entry) or they can acquire an existing incumbent. In the U.S. cement industry, the comparative advantage (e.g., TFP or size) of entrants versus incumbents and...
