An econometric assessment of telecommunications prices and consumer surplus in Mexico using panel data

We analyze telecommunications prices in Mexico by using a panel data of countries similar to Mexico to estimate demand models for mobile and fixed-line telecommunications. We find that Mexico’s actual mobile and fixed-line prices are below the predicted prices based on similar countries’ prices. Mexican consumers are paying lower prices than what one would expect based on comparisons of comparable countries. We calculate that in 2011 Mexican consumers received at least $4–$5 billion (USD) in consumer surplus from these lower mobile prices and in 2010 they received over $1 billion (USD) in consumer surplus from these lower fixed-line prices. These findings are in contrast to the general perception that concentrated telecommunications markets in Mexico are resulting in high prices and harming consumers.     

X-Factor updating and total factor productivity growth: the case of peruvian telecommunications, 1996–2003

This paper measures TFP growth of Telefonica del Peru, and based on this growth rate computes a telecommunications X-factor or offset. More broadly the paper analyses the problem of updating an X-factor under existing price cap regulation. A revised offset must account for the possible restructuring of service offerings resulting from improved efficiencies in response to price cap incentives. Our updating framework focuses on efficiency criteria, and based on economic principles emphasizes the continuity between prior and continuing standards. In the case of Peru, based on annual average TFP growth of 1.66%, the X-factor is computed to be 4.06% per year. An erratum to this article can be found at     

Altitude as handicap in rank-order football tournaments

The structure of professional sports allows us to document predictions from the theory of rank-order tournaments (Lazear and Rosen 1981). In the context of South American FIFA World Cup Qualifiers, under the presence of heterogeneous agents, handicapping the best quality players may increase the tournaments’ efficiency by making the contest more competitive. In particular, we show that playing in high-altitude stadiums (above 2500 m) constitutes a handicap as the otherwise least competitive teams benefit from the existence of an altitude advantage.     

The Determinants of Pricing in the Mexican Domestic Airline Sector: The Impact of Competition and Airport Congestion

Low-cost airlines in Mexico affect the lowest-quoted fares of one of the two principal incumbent carriers, but have no effect on the lowest-quoted fares of the other incumbent carrier. The same conclusion holds for competition between incumbent carriers where the lowest-quoted fares of one of the incumbent carriers is lower when incumbents compete. Congestion at the Mexico City airport is limiting potential competition, with carriers being able to charge a significant price premium. This suggests that the societal costs of airport congestion can go well beyond the negative congestion externality and should also include the effects of reduced competition. These findings raise important public policy issues.     

The determinants of interest rates in European Union countries

One of the problems that has raised the interest of economists is to know the determinants of interest rates. In the case of the European Union, the existence of some coordination in the area of economic policies and having to fulfill some nominal convergence criteria have opened new possibilities to this field of research. In this way, possible relations among interest rates, prices, and exchange rates have been studied. This forces us to consider, among other questions, the concept of purchasing power parity and uncovered interest rate differential. The goal of this paper is to show the influence that German interest rates might have over other European Union countries. We will start by showing the essential elements of the equations to be estimated. Then we will carry out the empirical analysis for the case of six European Union countries.
