This paper presents a new approach for measuring the effects of competition on school performance. We use an equilibrium sorting model to generate an intuitive measure of the competition each school faces, captured by the slope of the school’s demand curve. We then show that this competition...

Mobile telecommunications operators routinely charge subscribers lower prices for calls on their own network than for calls to other networks (on-net discounts). Studies on tariff-mediated network effects suggest this is due to large operators using on-net discounts to damage smaller rivals....

Mobile telecommunications operators routinely charge higher prices for off-net than on-net calls. Previous research provides two alternative propositions on whether on-net / off-net price differentials (OOD) are more attractive for large or for small operators. On the one hand studies on...

Understanding the degree and evolution of competition across industries is an important step towards understanding the impact of economic reform and competition on economic growth in Vietnam during the economic transition. In this paper, we investigate evolution of competition in Vietnam during...

We develop a model of competition in the solar panel industry. Solar firms manufacture panels that are differentiated both vertically and horizontally, and compete by setting quantities. The equilibrium of the model is consistent with a set of stylized facts that we document, including variation...

This paper constitutes a new endeavor of investigating competitive conditions in European banking. Since the vast literature of competition modeling has produced mixed results, the proposed methodology goes one step further in order to investigate the intensity of key effects on bank competition...

It is usually believed that higher competition, implying more active firms, benefits consumers. We show that this may not be the case in an industry with asymmetric cost firms. A rise in the number of more cost inefficient firms makes the consumers worse-off in the presence of a welfare...
