I examine the relationship between bank efficiency and market power to test the quiet life hypothesis for a sample of 419 Latin American commercial banks between 1985 and 2010. A two-stage least squares model with instrumental variables controls for the simultaneous relationship between efficiency and market power. Citing developments in efficiency modelling, efficiencies are drawn from the random parameters stochastic frontier function model that treats unobserved heterogeneity, whilst conventional Lerner indices and the efficiency adjusted Lerner index proxy market power. The quiet life hypothesis is firmly rejected after various robustness checks. To test if bank restructuring and governance changes affect efficiency and market power, I use a difference-in-differences approach to determine the impact of bank privatisation and foreign acquisition of local banks on efficiency and market power. Privatisation is preferred over foreign acquisition though its impact is concentrated on efficiency rather than market power. The evidence suggests that bank restructuring has promoted competition at the expense of market power and yielded efficiency gains at banks under conditions of monopolistic competition.

We investigate the success of legislation aimed at increasing competition at highly concentrated U.S. airports, mainly by forcing these airports to increase the availability of scarce facilities. We use a multidimensional regression-discontinuity approach to exploit a sharp discontinuity in the law’s implementation and identify its effects. We find that fares decrease by 13.4% (20.2%) in markets with one (both) end point(s) covered. Approximately half of the decline is driven by the entry of low-cost carriers. We find little evidence that the fare declines were accompanied by a diminished quality of service, and passenger volumes increased, which suggests the legislation improved consumer welfare.

This paper determines management behaviour for European savings banks between 1990 and 1998. Following the Granger causality approach of Berger and DeYoung [Journal of Banking and Finance 21 (1997) 849], we examine the intertemporal relationships between loan loss provision, efficiency and capitalisation for European banks. In so doing, we provide a robustness test of the Berger and DeYoung results for US banks. The possible relationships between the variables imply different modes of management behaviour namely bad management, bad luck, skimping, and moral hazard behaviour. The econometric results suggest that the most pressing management problem for European banks is bad management. Generally speaking, the European findings are inconsistent with previous results from the US. One notable difference in management behaviour between European and US banks is that the former do not appear to engage in skimping behaviour. The European results are sensitive to the number of lags included in the model.

We estimate demand for residential broadband using high-frequency data from subscribers facing a three-part tariff. The three-part tariff makes data usage during the billing cycle a dynamic problem, thus generating variation in the (shadow) price of usage. We provide evidence that subscribers respond to this variation, and we use their dynamic decisions to estimate a flexible distribution of willingness to pay for different plan characteristics. Using the estimates, we simulate demand under alternative pricing and find that usage-based pricing eliminates low-value traffic. Furthermore, we show that the costs associated with investment in fiber-optic networks are likely recoverable in some markets, but that there is a large gap between social and private incentives to invest.

This paper examines the impact of changes in bank governance on bank performance for a sample of commercial banks operating in SE Asia between 1990 and 2003. We identify bank governance in terms of bank ownership and measure bank performance as rank order alternative profit efficiency, technical change, and productivity. The period was characterised by financial deregulation, the Asian crisis and bank restructuring programmes. To resolve financial distress, SE Asian authorities implemented inter alia bank privatisation programmes and widened access for foreign ownership. Our results tend to support bank privatisation and the repeal of state ownership on economic grounds. We suggest the potential benefits of foreign ownership may take longer to be realised. For domestic private-owned banks, the challenge is improving bank efficiency.

Competition authorities have expressed concern that firms selling broadband internet and TV subscriptions may employ usage-based pricing (UBP) of internet to steer consumers toward TV over streaming video. We study this issue with household-level panel data from an internet service provider's UBP experiment, capturing the prices' effects on internet and TV subscriptions, internet usage, and firm revenue. We find that this specific UBP policy largely served to meter internet usage by high-demand households rather than steer them toward TV. Households' payments increased due to usage-related overage charges and internet subscription upgrades to avoid overages. Some households avoided internet-related payments by reducing usage rather than adding TV subscriptions.

The video entertainment industry is experiencing increases in over-the-top (OTT) video usage and cord-cutting behavior. Using unique panel data from 2012–2016, we document the behavior of the 2.4% of households who “cut the cord” annually. After dropping TV, these households increase internet usage by 22%, reduce payments to multiple-system operators (MSOs) by 50%, and 16% acquire new OTT video subscriptions. These results indicate meaningful substitution between OTT video and TV and suggest that competition authorities should consider broadening market definitions. MSOs appear to have little incentive to degrade OTT video, despite OTT video's contribution to declining TV revenues.

This paper contributes to the bank efficiency literature through an application of recently developed random parameters models for stochastic frontier analysis. We estimate standard fixed and random effects models, and alternative specifications of random parameters models that accommodate cross-sectional parameter heterogeneity. A Monte Carlo simulations exercise is used to investigate the implications for the accuracy of the estimated inefficiency scores of estimation using either an under-parameterized, over-parameterized or correctly specified cost function. On average, the estimated mean efficiencies obtained from random parameters models tend to be higher than those obtained using fixed or random effects, because random parameters models do not confound parameter heterogeneity with inefficiency. Using a random parameters model, we analyse the evolution of the average rank cost efficiency for Latin American banks between 1985 and 2010. Cost efficiency deteriorated during the 1990s, particularly for state-owned banks, before improving during the 2000s but prior to the sub-prime crisis. The effects of the latter varied between countries and bank ownership types.

Using a dataset of 7635 observations on 1384 commercial banks operating in the EU between 1993 and 2001, we utilise a mixed logit model to identify factors that explain the probability of a bank being a best [worst] performer. The empirical evidence confirms the importance of country-level characteristics (location and legal tradition), and firm-level features (bank ownership, balance sheet structure and size). Specifically, smaller sized banks with higher loan-intensity, and foreign banks from countries upholding common law traditions have a higher probability of best performance.
