A simple game-theoretic analysis of peering and transit contracting among Internet service providers

The paper presents a simple game-theoretic model of two Internet service providers (ISPs), drawn from a larger set consisting of Tiers-1 and -2 ISPs, who choose between peering and transit agreements. The study focuses on the costs of interconnection taking into account traffic imbalances. The analysis suggests that if the traffic flows and the costs of interconnection are fairly shared, the provider's peer, otherwise they choose transit. Moreover, the joint profits are maximized under the transit arrangement.     

WHAT DETERMINES RELIGIOUS SCHOOL CHOICE? THEORY AND EVIDENCE FROM RURAL BANGLADESH

This paper looks at the determinants of school selection in rural Bangladesh, focusing on the choice between registered Islamic and non‐religious schools. Using a unique dataset on secondary school‐age children from rural Bangladesh, we find that madrasah enrolment falls as household income increases. At the same time, more religious households, and those that live further away from a non‐religious school are more likely to send their children to madrasahs. However, in contrast to the theory, we find that Islamic school demand does not respond to the average quality of schools in the locality.     

Stock prices and merger movements: Interactive relations

Zusammenfassung Die wechselseitigen Beziehungen zwischen Aktienkursen und Firmenzusammenschlüssen. - Der Aufsatz untersucht die Beziehungen zwischen Firmenzusammenschlüssen und makro?konomischen Variablen. Es werden Kausalit?tstests mit US-Daten der Periode 1919–1979 durchgeführt, die zeigen, da? Zusammenschlüsse und Aktienkurse in derselben Periode aufeinander einwirken und da? keine Lead- oder Lag-Beziehungen bestehen. Die Zeitreihenanalyse deutet darauf hin, da? die Reihe der Zusammenschlüsse einem autoregressiven Proze? 2. Ordnung folgt, die „random walk”-Hypothese also abzulehnen ist.

Résumé Cours des actions et mouvements de fusion: Relations interactives. - Dans cet article l’auteur examine la relation entre des mouvements de fusion et des variables macro-économiques. Après avoir testé la causalité avec des données des E.U. pour la période 1919–1979, l’évidence démontre que l’activité de fusion et les cours des actions interagissent dans la même période et ne revèlent pas une relation d’avance ou à retard. L’analyse des séries chronologiques indique que la série de fusion suit un processus AR (2), refusant l’hypothèse de ?random walk?.

Resumen Precios de valores bursátiles y la pauta de fusiones: relaciones interactivas. - En este trabajo se examina la relación entre la pauta de fusiones y variables macroeconómicas. Los resultados de tests de causalidad utilizando datos de los EE UU para el período 1919–1979 muestran que las fusiones y los precios de las acciones interactúan en forma comtemporánea y no revelan rezago o adelanto alguno. El análisis de series de tiempo indica que las series de fusiones responden a un proceso AR(2), lo cual significa un rechazo de la hipótesis del ?random walk?.
