This paper investigates the impact of schools banning mobile phones on student test scores. By surveying schools in four English cities regarding their mobile phone policies and combining it with administrative data, we find that student performance in high stakes exams significantly increases...

We find that institutional ownership in publicly traded companies is associated with more innovation (measured by cite-weighted patents). To explore the mechanism through which this link arises, we build a model that nests the lazy-manager hypothesis with career-concerns, where institutional...

Interconnection rates are a key variable in telecommunications markets. Every call that is placed must be terminated by the network of the receiving party, thus the termination end has the characteristic of an economic bottleneck and is subject to regulation in many countries. This paper...

This lecture argues that mental health is a major factor of production. It is the biggest single influence on life satisfaction, with mental health eight years earlier a more powerful explanatory factor than current income. Mental health also affects earnings and educational success. But, most...

A large literature in behavioral and social sciences has found that human wellbeing follows a U-shape over age. Some theories have assumed that the U-shape is caused by unmet expectations that are felt painfully in midlife but beneficially abandoned and experienced with less regret during old...

We re-consider the impact that regulation of call termination on mobile phones has had on mobile customers' bills. Using a large panel covering 27 countries, we find that the "waterbed" phenomenon, initially observed until early 2006, becomes insignificant on average over the 10-year period,...

This paper examines the impact of regulatory intervention to cut termination rates of calls from fixed lines to mobile phones. Under quite general conditions of competition, theory suggests that lower termination charges will result in higher prices for mobile subscribers, a phenomenon known as...

This paper analyses the interaction between credit constraints and trading behaviour. I construct a unique dataset containing firm-level trade transactions data, balance sheets and credit scores from an independent credit insurance company for Belgian manufacturing firms between 1999 and 2007....
