Commercial cattle farming in Namibia, a prime example of livestock farming in semi-arid rangelands, is subject to a variety of risks, predominant among which is precipitation risk. At the same time it suffers from rangeland degradation that is at least partly due to inadequate management. We...

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 explores the impact of technological change on industry concentration and the underlying firm dynamics. In the agent-based model EURACE@Unibi I implement a paradigm shift in the technological frontier - a shift from a slow to a fast growing regime. The analysis shows that the...

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...

Between September 2021 and April 2022, anhydrous ammonia prices in the United States more than doubled, topping out at a record-high $1,300/ton. At the time, Senator John Boozman, Ranking Member of the Senate Committee on Agriculture, Nutrition, and Forestry, asked the Agricultural & Food Policy...

Price-concentration studies in banking typically find a significant and negative relationship between consumer deposit rates (i.e., prices) and market concentration. This relationship implies that highly concentrated banking markets are "bad" for depositors. It also provides support for the...

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....

We find evidence that the underperformance of some IPOs, and firms in concentrated industries, have common empirical roots. The most likely explanation for both is a confluence of two well known rational theories, which predict that: (1) entrepreneurs in concentrated industries optimally time...

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...
