The effects of incentive regulation in the telecommunications industry: A survey

We review recent empirical studies of the performance of incentive regulation in the telecommunications industry. These studies provide evidence that productivity, infrastructure investment, profit levels, telephone penetration, and new service offerings have increased under incentive regulation. Service rates have generally remained stable or decreased slightly, and service quality does not appear to have been affected adversely. There is no evidence that incentive regulation has led to streamlined regulatory proceedings. Strong evidence that incentive regulation has reduced the costs of providing telephone service has not yet materialized.We thank Sanford Berg, Alex Larson, Larry Schelhorse, and Timothy Tardiff for very helpful comments and discussion. We are also grateful to Michael Crew and Ingo Vogelsang for a particularly careful and insightful review of this paper.     

Incentive regulation and investment: evidence from European energy utilities

This paper investigates the relationship between investment and regulatory regimes (incentive vs. rate-of-return regulation) for a sample of EU energy utilities from 1997 to 2007. We control for the effect of firm ownership and for cross-country differences in the underlying energy demand and energy supply. To deal with potential endogeneity of the regulatory regime, we apply instrumental variable methods (2SLS and GMM). Our results show that investment rate is higher under incentive regulation than under rate of return regulation. Using original data on the regulatory tools (X factor and WACC), we find that investment of incentive regulated firms appears highly sensitive to the X factor, consistent with efficiency- and profit-seeking motivations. Electric utilities investment is also sensitive to the level and change in the weighted average cost of capital (WACC). Finally, we find that the positive relationship between private control and investment is not robust to IV estimations, suggesting that in Europe regulation may have reduced the differences between private and public firms’ incentives to invest.     

Price Caps,Rate of Return Constraints and Universal Service Obligations

This paper evaluates the effects of modifying price cap regulation when firms are allowed to use non-linear tariffs. We consider a stylized network industry and analyze price cap regulation combined with rate of return regulation and with a universal service obligation. While both modifications can increase aggregate welfare by reducing the pricing distortions under price cap regulation, a universal service obligation is welfare superior if the firms profits and the size of its network are held constant.     

COST‐SAVING PRODUCTION TECHNOLOGIES AND STRATEGIC DELEGATION*

This work analyses a managerial delegation model in which firms choose between two production technologies: a low marginal cost technology and a high marginal cost technology. For the former to be adopted more investment is needed than for the later. By giving managers of firms an incentive scheme based on a linear combination of profit and sales revenue, we find that Bertrand competition provides a stronger incentive to adopt the cost‐saving technology than the strict profit maximisation case. However, the results may be reversed under Cournot competition. If the degree of product substitutability is sufficiently low (high), the incentive to adopt the cost‐saving technology is larger under strict profit maximisation (strategic delegation).     

A two-sector Kaleckian model of growth and distribution with endogenous productivity dynamics

This study extends a two-sector Kaleckian model of output growth and income distribution by incorporating endogenous labour productivity growth. The model is composed of investment goods and consumption goods production sectors. The impact of a change in wage and profit shares on capacity utilisation and output growth rates at the sectoral and aggregate levels are identified. The study reveals short-run cyclical capacity utilisation rates and productivity growth dynamics. Even if the short-run steady state is stable, the capital accumulation rate in the consumption goods sector must decrease more than that in the investment sector for long-run stability. When simultaneous rises in profit shares in both the sectors affect long-run aggregate economic growth differently at a steady state, the distributional interests between the same class in different sectors may hamper the long-run economic growth. A policy message is that the effect of income distribution on industrial output growth is not always beneficial. These phenomena are specific to two-sector models and cannot be observed when using conventional aggregate growth models.     

Regulation of network infrastructure investments: an experimental evaluation

This paper reports the results of an experiment evaluating three regulatory schemes for network infrastructure, in terms of their ability to generate efficient levels of capacity investment. We compare the performance of (1) price cap regulation, (2) a regulatory holiday for new capacity, and (3) price cap regulation with long term contracts combined with a secondary market. The setting is one in which network users can benefit from acting strategically, and are better informed than the network operator about demand growth. We find that the regulatory holiday creates an incentive to underinvest relative to optimal levels. Long term contracts also fail to improve on single price-cap regulation, and may reduce investment by providing noisier signals about future demand.     

A model of incentive regulation

A method of incentive regulation is presented. The regulatory agency sets a‘fair rate of return’ which is used to determine a ‘target’ profit for the regulated firm. If the firm's actual profit differs from the target profit, it retains a fraction of the excess (or absorbs a fraction of the deficit). This feature of the system provides a strong incentive for efficient operation. Properties of the incentive system are explored and problems of implementation are briefly examined.     

Incentive regulation,service quality,and standards in U.S. electricity distribution

The widespread use of incentive regulation in telecom, electricity, and other industries in the U.S. and elsewhere has raised questions about its possible adverse effect on the quality of service. This paper examines U.S. electricity distribution utilities in the years 1993–1999, several of which were subject to incentive regulation. Controlling for other possible influences, including possible endogeneity of the regulatory regime, the data and model indicate that incentive regulation is indeed associated with significantly longer duration of service outages, although not necessarily more frequent outages. Importantly, this quality reduction is offset in cases where regulation incorporates service quality standards. We also examine the causal chain connecting incentive regulation, cost expenditures, and service quality. We conclude that careful design of quality standards can allow incentive regulation to achieve cost savings without quality degradation.     

Separation of Regulatory Powers When Contracts Are Incomplete

The investment of a regulated firm affects the service/good provided on many dimensions. Should an integrated regulator take care of them all? Or is it better to have separate regulators responsible for them? We analyze the effect of the separation of regulatory powers on the regulated firm's ex ante incentive to invest in a “cooperative” innovation. The effects of the innovation are not verifiable and the cost of investing is sunk, hence, there is a problem of hold‐up. We find that when the innovation produces opposite effects the ex ante firm's incentive to invest is larger in the case of separation than in the case of integrated regulation. We also stress the risk of over‐investment that the separation of regulatory powers may induce. We maintain that along with classical incentive regulation—which mainly provides incentives for the firm to be efficient—the separation of regulatory powers may play a role in providing an incentive for cooperative innovations.     

THE EFFECT OF REGULATION ON WAGES AND INTERMEDIATE PRODUCT PRICES UNDER BILATERAL MONOPOLY1

This paper seeks to determine whether, under bilateral monopoly, profit rate regulation induces an input price bias in addition to the well known Averch-Johnson capital intensity bias. Using a Nash-type employer-union, fixed bargaining power model, it is found that regulation may induce lower as well as higher wage rates. Similarly, when the two parties are respectively capital equipment supplier and user, regulation of the user's profit rate has an ambiguous effect on the equipment rental rate. In both cases the input price effect is shown to depend on the elasticity of factor substitution and on how demand elasticity varies with output.     

考虑集成商营销努力的养老服务提供商服务质量激励研究

在考虑养老服务集成商营销努力的情况下,通过设计成本分担契约、收益共享契约激励养老服务提供商改善服务质量,分析了两类激励契约的适用条件;比较了对养老服务质量、营销水平决策和各成员利润的改善作用。研究结果表明：提供商的服务质量、利润会随着成本分担比例的增加而递增,随着收益共享比例的增加而递减;集成商的营销水平会随着成本分担比例的增加而增加,而随着收益共享比例的增加而递减,利润水平会随着成本分担比例和收益共享比例的增加而递减;需求影响系数对三种情境下的提供商和集成商利润产生正向作用,签订成本分担契约对提供商较为有利,集成商可能更倾向于收益共享契约;成本影响系数则对利润产生负向作用,签订收益共享契约对提供商较为有利,对于集成商来说,其利润在三种情境下的差异不大;成本分担契约对激励提供商改善服务质量和集成商提升营销水平具有最佳的激励作用。在大多数情况下,提供商获得的利润总是高于集成商。     

Firm performance and corporate finance in New Zealand

Low productivity growth in New Zealand has been a paradox. We study New Zealand firms’ profitability, in terms of profit margin and return on assets (ROA), from the viewpoints of productivity enablers using firm-level panel data. We find that tangible fixed investment and a research and development (R&D) tax incentive are associated with higher profitability performance. In addition, the firm size is found to be a key determinant of profit margin. By contrast, we do not find any evidence that intangible investment can improve the profitability. The global financial crisis has not changed the leverage effect on ROA in New Zealand, while the impact of R&D became more prominent after the crisis.     

Incentive Regulation and Telecommunications Service Quality

We examine the impact of incentive regulation—price regulation and earnings sharing regulation—on retail service quality in the U.S. telecommunications industry between 1991 and 2002. We find that incentive regulation is associated with significantly higher service quality on several dimensions (e.g., more rapid installation of new telephone service, fewer trouble reports, and increased customer satisfaction) but significantly lower quality on some dimensions (fewer installation commitments met and longer delays in resolving reported service problems)JEL Classification: L51, L96, L15We thank Michael Crew and two anonymous referees for helpful comments and suggestions.

Strategic Firm Behavior Under Average-Revenue-Lagged Regulation

Price caps have been shown to have incentive properties superior to traditional rate of return regulation. Average-revenue-lagged regulation (ARL) is attractive in that steady-state prices are known to be efficient. We show that the ARL scheme can be manipulated by the firm so as to yield the unregulated global profit maximum. While tests exist that can provide the regulator with evidence of this strategic behavior, we also demonstrate that the unregulated global profit maximum will not be attainable if Laspeyres (L) regulation is employed.Jel classification: L43, L51I would like to thank Michael Crew and an anonymous referee for their extremely helpful suggestions.     

政府权力、营利性扩张与通货膨胀

本文从政府权力视角,设立分权制度下中央、地方两级政府的目标函数,分别在大政府范畴的预算约束条件下求解其最优选择和长期稳态路径。本文的结论是,长期稳态价格水平不仅取决于中央、地方两级政府的债务规模、税收与支出,而且还受到国有企业投资的影响;中央政府的投资、债务、利润与货币增长之间相互推进,地方政府为扩大投资竞争融资来源具有强烈的货币增长需求,这倒逼货币供给增加;通货膨胀主要原因之一就是政府权力软约束下的营利性投资扩张。因此,治理通货膨胀的必要条件是,设计一种政府与治理通货膨胀具有共融利益的制度,减少政府营利性的准公共投资,增加事关国计民生的纯公共支出。     

Wages and International Tax Competition

We introduce wage bargaining and private information into a model of profit shifting and tax competition between a large and a small country. Shifting profits to the small country not only reduces a firm's tax bill but also creates private information on profitability, altering the wage bargaining in favor of the firm. This additional shifting incentive makes the tax base of the large country more elastic and leads to higher outflows, lower wages, higher firm profits and lower equilibrium tax rates. Tax rates are no longer the only determinant of the direction and extent of profit shifting.     

Economic stagnation in Weimar Germany: a structuralist perspective

Mexico and Argentina in the 1990s as well as Weimar Germany in the 1920s implemented similar exchange-rate-based stabilization programs which were successful in stopping inflation, but failed to generate the domestic savings and investment rates necessary for a sustainable growth path. It is argued that in both cases substantial foreign capital inflows were attracted by a stable nominal exchange rate and high interest rates, which alleviated the distributional struggle driving high inflation. However, this incentive structure caused a profit squeeze in the tradable goods sector due to an appreciating real exchange rate precipitating the ultimate collapse of the programs.     

Incentive Regulation and The Cost Structure of The Local Telephone Exchange Network

This paper combines an engineering process model of the cost of local exchange telecommunications firms with an analytical model of optimal incentive regulation (with ex post cost observability), to study empirically the properties of the optimal regulatory mechanism. Relying on detailed properties of the cost function, we examine three issues: (i) the extent of natural monopoly when informational rents associated with regulation are taken into account; (ii) the extent of incentive correction, which expresses the divergence of pricing under the optimal mechanism from optimal pricing under complete information; (iii) the implementation of optimal regulation through a menu of linear contracts. Our findings are that, for fixed territory, strong economies of scale allow local exchange telecommunications to retain monopoly characteristics even when the (informational) costs of regulation are properly accounted for, the incentive correction term is small in magnitude, and that optimal regulation can be well approximated through relatively simple linear contracts.     

A mark-up pricing model for price simulations

This paper develops an input/output model of pricing using a mark-up pricing formula. The connection between mark-up pricing and competitive pricing is analyzed through the determination of sectoral equilibrium profit mark-up rates as a function of the profit rate and the capital intensity of each sector. The model is used to analyze the effects on relative prices and the aggregate price level of exogenous changes in the nominal wage rate, tax rates, the exchange rate and world prices. Exogenous changes in the prices of domestically produced commodities are modelled via the imposition of ad valorem tax rates, which yield a measure of the net effect of the exogenous changes. Simulations are carried out under passive price adjustment as well as adjustment with price ceilings. In this last instance the model calculates the endogenously determined reduction in profit mark-ups. Lastly, empirical results of various simulations are presented using data from the Mexican economy.
