Telephone pricing structures: The effects on universal service

We use 1987 data to study the household demand for access to the telephone system. Previous analyses find demand to be highly inelastic and, therefore, predict that local rate increases will have little impact on the goal of providing universal telephone service. We estimate that price has a considerably stronger effect on access demand, especially at low incomes, and argue that elasticities increased in the 1980s. But our evidence also suggests that the structure of telephone rates matter: where local measured service is available, changes in flat rate prices have no effect on access demand.     

Regulating prices for shifting between service providers

The price that a regulated access provider charges for shifting customers between service providers has significant welfare implications. Typical regulatory approaches to pricing, such as pricing based on fully allocated cost or incremental cost, ignore the characteristics of consumer demand. A theoretical alternative, Ramsey pricing, considers only the elasticity of demand for given products. This paper directs attention to the competitive process. Using US long-distance telephone services as an example, this paper shows how empirical evidence concerning customer acquisition costs, customer switching costs, and churn among service providers can help to inform price regulation.     

Efficiency versus social optimality: The case of telecommunications pricing

Standard arguments for efficiency-based pricing policies break down once it is admitted that no lump-sum transfers and taxes are available. In this paper, it is argued that the appropriate solution is to equate the marginal welfare cost of redistributing income through pricing policies that deviate from marginal cost with the marginal cost of redistribution through the tax and welfare systems. For telecommunications pricing, this solution may be implemented by charging usage prices for long-distance services in excess of marginal cost and making corresponding reductions in fixed access charges. An illustrative example, based on data for Australia, is presented.     

The Welfare Costs of the Australian Telecommunications Pricing Structure*

Australian telecommunications pricing has developed in an environment which is uncompetitive, subject to pressures to cross-subsidize and insufficiently cognizant of relevant costs and demands. STD and local call charges are too high and access charges too low. Compared with a structure which charged marginal usage costs and retrieved costs of subscribers' loops and overheads through access charges, the pricing structure has an estimated efficiency cost of about $240 m in 1985–86.     

Conjoint analysis of demand for IP telephony: the case of Japan

With the recent diffusion of broadband (BB) services, Internet protocol (IP) telephony is expected to spread significantly in Japan. This article investigates the demand for IP telephony by using conjoint analysis. Projecting IP telephony demand also contributes to Japanese info-communication policy discussions. Two points are made. First, IP telephony is still currently considered an optional supplement or an add-on service option of high-speed BB Internet access services in Japan rather than a close substitute of existing plain old telephone service (POTS). At this point, we find little evidence that many households will promptly forsake their fixed line service for IP telephony. Second, we conclude that the key condition for the proliferation of IP telephony is the complete guarantee of quality of service (QoS), including voice quality, number portability, fax usage and emergency access, comparable to or exceeding that of existing POTS.     

Interstate switched access demand analysis

The breakup of the Bell System in 1984 led to the adoption by the Federal Communications Commission of a system of tariff charges that are paid to local exchange carriers by business and residential telephone subscribers, and interexchange carriers such as AT&T. These charges are designed to recover the costs associated with providing access to the public switched network to complete interstate calls. This system is known as the FCC Access Charge Plan. Flat-rate fees, named Subscriber Line Charges, are imposed on telephone subscribers, while usage-based charges are billed to interexchange carriers. These are called Carrier Common Line and Traffic Sensitive rates. Since CCL and TS rates are based on network usage, forecasts of switched access demand are required to set them properly.This paper presents an econometric model of interstate switched access demand developed and utilized by AT&T to produce forecasts of 1988 demand in connection with the Annual 1988 Access Tariff Filings. The model is estimated in a state-level pooled cross-sectional time-series framework, with dynamics introduced via polynomial distributed lags on price and income. It represents an extension of the econometric demand model developed and used by the FCC a year earlier to determine a reasonable forecast of 1987 Carrier Common Line switched access demand. Estimated demand elasticities and forecasts are provided. The model forecasts are also compared to those from other models.     

Strategic choice of financing systems in regulated and interconnected industries

The growing importance of inter-network exchanges in infrastructure-based utilities influences regulatory choices and access pricing for downstream services using the networks. We analyze this problem in a setting where the infrastructure managers of two bordering countries are in charge of pricing the access to their networks for downstream transport firms that provide international services. Network costs can be financed through public funds and user charges.In this context, access prices are affected by the incomplete internalization of consumers' surplus and infrastructure costs; we analyze how this distortion at the access pricing level generates a distortion in the levels of public funds dedicated to infrastructure financing.Because of these distortions, it turns out that in a non-cooperative setting the second-best outcome might consist in the simultaneous adoption of a no-subsidy system. However, multiple equilibria typically exist and the second-best outcome is never a stable equilibrium. Other properties of the different possible equilibria are studied, as well as the impact of supra-national policies aimed at encouraging the development of international services. Finally, we show that the coordination problems deriving from the existence of multiple equilibria can, sometimes, be solved by separating the choice of a regulatory mode from the access pricing stage, thereby allowing the infrastructure managers to commit to use a specific financing system before setting the access price.     

Calling Patterns and Usage of Residential Toll Service under Self Selecting Tariffs

Using a nested logit model, we empirically show how self-selecting tariffs with basic and OCP (Optional Calling Plan) service options affect households' calling patterns and usage of interstate toll service in the United States. We find, first, that households are more sensitive to price declines than to price increases in terms of both consumption and expenditures. Second, households respond more sensitively to OCP price changes than to basic service price changes. Third, consumption changes are more sensitive than expenditures, indicating that households adjust their calling patterns or service options so as to keep expenditures on telephone bills relatively constant.     

Access charges under two-tier pricing

This article analyzes the regulation of access charges in a liberalized postal market where operators use two-tier pricing. It develops a model of vertical product differentiation that allows determination of the demand for First and Second Class mail from an incumbent postal operator and a group of entrants. The optimal access charges for First and Second Class letters are determined as well as the optimal quality for these services.      

Pricing access in network competition

We compare various access pricing rules in the two-way access model. We show that the Generalized Efficient Component Pricing Rule (TECPR) leads to a lower equilibrium price than does the Efficient Component Pricing Rule, (ECPR) marginal cost pricing, (MCP) and any non-negative fixed access charges.      

Demand for telephone lines and universal service in Spain

In this paper we analyse the effects of some proposed tariff scenarios on universal service in Spain. For that, we use a model of demand for telephone lines to derive an econometric model of the net demand for new access lines, for the period 1980–1993, using quarterly observations. We use cointegration techniques to obtain long and short run equations. We conclude that a tariff restructuring that lowers the installation charge and domestic traffic rates while moderately raising recurring charges might have a small effect on the net demand for new lines. This suggests that the objective of universal service may be compatible with some of the tariff structures that have been recently considered in Spain.     

Some recent developments in capital market theory: A survey

This paper surveys some recent developments in the theory of capital markets. Particular emphasis is given to two strands of the literature. The first covers some recent and fundamental extensions to the theory of risk aversion and the demand for risky assets. These papers are concerned with the effect of non-hedgeable background risk on risk attitudes. The important implications for finance are for the size of the risk premium (the equity premium puzzle) and for the demand for and pricing of contingent claims. For example, background risk may help to explain the apparent over-pricing of options on equity indices. The second topic is interest rate term structure models. Stochastic term structure models try to capture the possible future shapes of the term structure of interest rates. This is relevant for the pricing of contingent claims, in particular for the pricing of interest rate derivatives such as American-style swaptions. The paper will survey the most important recent models in the literature, each of which satisfies the fundamental no-arbitrage property. It will discuss the implications of the models for the pricing of both European-style and American-style options.     

ICT for financial access: Mobile money and the financial behavior of rural households in Uganda

Mobile money usage has expanded tremendously in Uganda, reaching over 40% of the adult population within 8 years of inception. We use data from 820 rural households to examine the effect of this financial innovation on their financial behavior. We find that using mobile money services increases the likelihood of saving, borrowing, and receiving remittances. The corresponding amounts of each service are also significantly higher among mobile money user households relative to their nonuser counterparts. We demonstrate that the mechanism of this impact is a reduction in transaction costs—a combination of transportation fares and service charges—associated with household proximity to mobile money agents. To illustrate the convenience of service proximity, we demonstrate that the household's likelihood and frequency of using mobile money services reduces with the distance to the nearest mobile money agent. This distance variable is then used to instrument for the potentially endogenous mobile money adoption. We finally perform propensity score matching to reinforce the robustness of our results; our results are consistent across all these specifications. The results imply that developing and enhancing access to and usage of pro‐poor financial products could be a first step to achieving greater financial inclusion.     

Access prices,unbundling and product variety in European Internet markets

A fundamental policy in European broadband regulation is unbundled access to the local loop of the incumbent telephone company. We present comparative static results that show as the access price decreases, the retail price decreases, the variety of plans offered by Internet service providers increases and the quantity of each variety increases when a threshold condition is met. Using data from 18 European countries from 2006 to 2012, we find empirical support for these results when Internet product variety is measured by variation in download speeds.     

Russian Railways Reform and the Problem of Non‐discriminatory Access to Infrastructure

Abstract Restructuring of the Russian railways system is well under way. Among the policies just now coming into practice are two that are standard in railways restructuring in other countries: the provision of access to the infrastructure by independent train operating companies, and assurances of non‐discriminatory access terms for such companies. However, 'discrimination'– in the traditional economic sense – is a standard and often welfare‐enhancing pricing strategy for the recovery of fixed costs in a sector, like railways, with declining average costs. If competition regulators are unable to distinguish between discrimination that harms competition and discrimination designed only to recover fixed costs, policy makers in Russia and elsewhere will face a choice between large government subsidies and large welfare losses. In these circumstances, other restructuring models should be considered.     

Options for Electricity Transmission Regulation in Australia

The pricing of access to electricity transmission networks in Australia is currently under review. Several options have been proposed including those based on nodal pricing and the assignment of transmission rights contracts. As most of the marginal costs of transmission are recovered through wholesale electricity prices we focus on the key issue of regulation and investment incentives. We find that current options are unlikely to be adequate in terms of encouraging socially optimal levels and timing of new transmission investment. As an alternative, we propose a regulatory scheme, based on a related idea by Sappington and Sibley that can overcome this problem. Our scheme can potentially generate first best results and is readily applicable given the current institutional structure of electricity markets in Australia.     

Pricing flexibility under rate-of-return regulation: Effects on network infrastructure investment

When a commodity market relies upon a regulated network service industry—e.g., telecommunications, electricity, or natural gas transmission—economic efficiency in that commodity market is a crucial consideration for regulatory design. This is because insufficient infrastructure investment relative to network demand results in congestion. The extraction of associated rents has distortionary effects on commodity spot market prices. Greater regulatory flexibility in network pricing can alleviate such issues by cultivating the incentives needed for stakeholders to invest in transmission capacity. To illustrate this effect I derive and numerically solve stylized optimality conditions for access and usage prices for a gas pipeline operator under alternative regulatory models. My results have general implications for regulation in network infrastructure industries, as energy and telecommunications markets are expected to expand considerably over the coming decades.     

Efficient price and capacity choices under uncertain demand: An empirical analysis

Traditional economic analyses of the peak-load problem typically assume an unrealistic degree of regularity in demand during well-defined peak and off-peak periods. This issue is addressed through a comprehensive statistical model that separates demand into its systematic and stochastic components. This model is combined with a traditional economic model and applied to local telephone service, leading to substantive conclusions relevant for managerial decisions as well as further research, among them:

? Neglecting the systematicand stochastic structure of demand may lead to inefficient tariffs. Efficient measured service structures typically price individual callsbelow incremental capacity cost.

? Industry wide capacity decision rules that are exclusively driven by blockage probability targets during narrowly defined time periods may be economically inefficient.

? For telephone service, spot pricing, which sets high prices during periods ofactual congestion, has the potential to be considerably more efficient than traditional tariffs that set high prices during periods ofexpected congestion.
