Spectrum Auction Tragedies: The Case of the Mexico Spectrum Auction for AWS Services

Last July 19th the Mexican Federal Government concluded the auction of the 1.9/2.1 GHz band blocks for Advance Wireless Services (AWS). The auction design and the spectrum cap impose by the Federal Competition Commission led to the participation of only one bidder with a price at the minimum posted by the government for one of the two national coverage blocks put to auction. The remained nation block was not assigned because no bidders qualified and a third block identical to the national blocks was divided in 27 regional blocks but the auction final value was 28 times the minimum posted price for the national block. The social cost and the implicit subsidy generated by the auction result obey to an industrial policy in telecommunication oriented to pick winners and modify the market structure from the regulators goals instead of the market evolution.

An Examination of Frank Wolak’s Model of Market Power and its Application to the New Zealand Electricity Market

This paper is the second in a symposium of papers that examine the 2009 report by Frank Wolak into the New Zealand electricity market. In this paper, we discuss the Report’s measures of the ability and incentives of generators to exercise unilateral market power. We show that the construction and interpretation of these measures are highly sensitive to some key assumptions, particularly those concerning the elasticity of demand for electricity in the wholesale market and the amount of transmission loss on the national grid.Electricity markets; market power

Evidence of a Modest Price Decline in U.S. Broadband Services

In this paper, we construct a price index for broadband services in the United States between 2004 and 2009. We analyze over 1500 service contracts offered by DSL and cable providers in the United States. We employ a mix of matched-model methods and hedonic price index estimations to adjust for qualitative improvements. In general, we find some evidence of a quality-adjusted price decline, but the evidence points towards a modest decline at most. Our estimates of the price decline range from 3% to 10% in quality-adjusted terms for the five-year period, which is faster than the BLS estimates for the last three years. These modest price declines look nothing like other parts of electronics, such as computers or integrated circuits, which raises many questions. The results also inform a range of policy discussions about US broadband services.

The Law, Culture, and Economics of Fashion

Fashion is one of the world's most important creative industries. As the most immediate visible marker of self-presentation, fashion creates vocabularies for self-expression that relate individuals to society. Despite being the core of fashion and legally protected in Europe, fashion design lacks protection against copying under U.S. intellectual property law. This Article frames the debate over whether to provide protection to fashion design within a reflection on the cultural dynamics of innovation as a social practice. The desire to be in fashion - most visibly manifested in the practice of dress - captures a significant aspect of social life, characterized by both the pull of continuity with others and the push of innovation toward the new. We explain what is at stake economically and culturally in providing legal protection for original designs, and why a protection against close copies only is the proper way to proceed. We offer a model of fashion consumption and production that emphasizes the complementary roles of individual differentiation and shared participation in trends. Our analysis reveals that the current legal regime, which protects trademarks but not fashion designs from copying, distorts innovation in fashion away from this expressive aspect and toward status and luxury aspects. The dynamics of fashion lend insight into dynamics of innovation more broadly, in areas where consumption is also expressive. We emphasize that the line between close copying and remixing represents an often underappreciated but promising direction for intellectual property today.

Designing Competition Policy for Telecommunications

This paper explores the role of the essential facilities doctrine in circumscribing the scope of network sharing obligations in telecommunications. Among other things it argues that a proper application of the doctrine of essential facilities should recognize the prominence of dynamic over static efficiency in promoting consumer welfare. Regulators may be averse to recognizing these tradeoffs because unlike the behavior of prices the welfare losses from foregone innovation may be unobservable to the regulators’ constituency. Moreover, an emphasis on dynamic efficiency requires the short-term regulator to take the “long view” – fostering the competitive process rather than emulating the competitive outcome.

Competition Policy in Small Distant Open Economies: Some Lessons from the Economics Literature

New Zealand is a small open economy that is remote from all major markets. The smallness and remoteness of New Zealand combine to imply that this country has, at least quantitatively, distinctive features for the regulation of economic activity by competition law. The isolation and small size of the economy mean that typically all but exporting firms are small as judged on a world scale, and that domestic markets are small and generally highly concentrated. This paper reviews the economic literature on the implications of an economy’s size and isolation for competition law. The literature suggests that principles underlying competition law do not change for small economies, but that the application of competition law should be different. In small economies, low regulatory and tax barriers to trade dominate the importance of competition law for good economic performance of domestic markets. In these economies, competition law should focus on economic benefit/detriment evaluations of mergers and trade practices rather than rules of thumb of the sort based on measures of market structure and indicators of competition, or those aimed at prohibiting particular practices per se. Producers’ surplus should not be de-emphasised in the calculation of benefits and detriments in small economies; particularly for activities that relate in any way to (potential) export activity. For any economy, particularly in the presence of competition, cooperation enhances economic performance in specific circumstances. In small economies cooperation can be particularly efficient-for example, in achieving scale and thereby export performance-although it may entail interaction among a large fraction of players in an industry. The approach that the literature suggests to the application of competition law in small economies places relatively heavy weight on dynamic efficiency as the criterion for competition law design and enforcement. It is squarely in accord with recommendations in the literature on desirable competition law for the so-called new economy.Small; Isolated; Economy; Antitrust; New Zealand; Producer Surplus: Consumer Surplus; Competition Law; Economic Benefit; Economic Detriment; Rule of Reason

A Critique of Wolak’s Evaluation of the NZ Electricity Market: Introduction and Overview

This paper is the first in a symposium of papers that examine the 2009 report by Frank Wolak into the New Zealand electricity market. The Wolak report concluded that there had been a cumulative total of $4.3b (NZD) of overcharging in the New Zealand wholesale market over a period of seven years. In this paper, we introduce the Wolak findings in the context of the salient features of the New Zealand market, and explain that this headline figure is highly sensitive to some (quite unrealistic) assumptions about the structure of this market. The papers that follow this introduction (Hogan and Jackson, 2011, and Evans and Guthrie, 2011) examine Wolak’s methodology and its empirical application.Wolak Report; electricity markets; market power

A New Zealand Electricity Market Model: Assessment of the Effect of Climate Change on Electricity Production and Consumption.

In this paper, we introduce an electricity market model and use it to explore the effect of climate change on electricity output and prices. It is calibrated to the New Zealand Electricity Market, and includes multiple generation fuels, uncertain fuel availability, and storage options. The model is formulated in continuous time, which mimics the many short trading periods that are common to electricity spot markets, while properly incorporating forward-looking generation decision making. Specifically, it is used to estimate the effects of changes that may arise in characteristics of fuels -water and gas- as a consequence of climate change and climate change policies. The model does this under the polar cases of a competitive market structure and monopoly. There are three key findings from the results. First, the results illustrate the importance of allowing for volatility and including management of storage in electricity market models. Second, they suggest that reductions in average hydro fuel availability will reduce welfare significantly. Increases in the volatility of hydro fuel availability will also affect welfare, but to a very small extent. Third, the value of reservoir expansion is sensitive to the distribution of hydro fuel availability. Finally, the effects of a carbon tax are also reported.dynamic optimisation, electricity spot market performance, stochastic fuel availability, storage options, climate change

Do Stationary Risk Premia Explain It All? Evidence from the Term Struct

Most studies of the expectations theory of the term structure reject the model. However, the significance of the rejections depend strongly upon the form of the test. In this paper, we use the pattern of rejection across maturities to back out the implied behavior of time-varying risk premia and/or market forecasts. We then use a new technique to test whether stationary risk premia alone can be responsible for these rejections. Surprisirj1y, this test is rejected for short maturities up to 6 months, suggesting that time-varying risk premia do not explain it all. We also describe hew this method can be used to test other asset pricing relationships.
