The impact of broadband quality standards on internet services market structure in Colombia

This paper develops a structural model which allows estimating the impact of regulatory decisions looking for the setting of download-speed standards on market structure and performance. We characterize a setting under which quality standards improve both service quality and availability. As to quality, we evaluate the impact of quality standards on the performance of local demand from a detailed database of broadband internet subscribers, discriminated by the main attributes of an internet subscription contract as location, supplier, monthly-fee, download- and upload-speed features. From these results, we are able to identify the effect of quality regulation on the behavior of internet providers in a differentiated product market approach. As a consequence, we are able to assert that the response of internet service providers to quality regulation is a more intense product differentiation that contributes to demand expansion and therefore to improve broadband penetration indicators.

A model of school behavior: tuition fees and grading standards

This paper uses a hybrid human capital / signaling model to study grading standards in schools when tuition fees are allowed. The paper analyzes the grading standard set by a profit maximizing school and compares it with the efficient one. The paper also studies grading standards when tuition fees have limits. When fees are regulated a profit maximizing school will set lower grading standards than when they are not regulated. Credit constraints of families also induce schools to lower their standards. Given that in the model presented competition is not feasible, these results show the importance of regulation of grading standards.
