This chapter investigates the impact of environmental taxation and subsidization on non-polluting renewable power plants. Their dispatch is prioritized in a wholesale electricity market in which oligopolistic firms produce electricity both from polluting fossil-fuel inputs and non-polluting renewable energy sources, and competitive fringe firms pro...

Market power in emissions trading has been extensively investigated because emerging markets for tradable emissions permits, such as the European Union's Emissions Trading Scheme (ETS), can be dominated by relatively few large sellers or buyers. Previous studies on market power in emissions trading have assumed the existence of a subset of competit...

This analysis investigates whether the Cournot model of imperfect competition holds true in the Japanese retail electricity market, using monthly data over the period 2005 to 2010. One concern about electricity markets that are open to retail competition is the potential for collusive behavior of some suppliers. A revealed preference test of the Co...

This article uses hourly data on household usage of an in-home display (IHD) in a randomized field experiment to investigate how acquiring information from IHDs affects electricity usage of households. Providing IHDs, which enables households to see a graph of their half-hourly electricity consumption in real time, is a promising policy interventio...

This chapter assesses the impact of applying critical peak pricing (CPP), in-home displays (IHDs), and home energy reports (HERs) to consumers living in the Kansai region based on the empirical results of field experiments presented in the previous chapters. For CPP, households with standard and all-electric contracts in the Kansai region are assum...

A serious concern about the supply shortage of electricity after the nuclear disaster in Fukushima, together with a growing concern about global warming, has enhanced the need to promote energy conservation in Japan. The residential sector, which is the focus of this book, has increased its share of total energy consumption for the past two decades...

This chapter investigates how acquiring information from in-home displays (IHDs) affects electricity usage through attention and learning, using the experimental data on the frequency of consumers’ use of IHDs in summer 2012 and winter 2012/2013. Households in the treatment group could see a graph of their half-hourly electricity consumption in rea...

Using data drawn from a 2013 field experiment, this chapter examines the energy-saving effects of home energy reports (HERs). HERs provide consumers with energy conservation tips and compare consumers’ energy usage with that of similar neighbors. These comparisons categorized consumers as “energy-using,” “average,” or “energy-saving.” The energy us...

Using data from a series of field experiments for the fiscal years 2012–13, this chapter investigates consumers’ electricity use in response to critical peak pricing (CPP) and conservation requests (CRs). CPP stimulates consumers’ extrinsic motivation to conserve energy by applying higher prices to electricity usage during peak periods. This is a p...

This article investigates whether the Cournot model of imperfect competition holds true in the Japanese retail electricity market, using monthly data over the period 2005–2010. One of the concerns about a retail electricity market that is open to competition is the collusive behavior of some suppliers, which leads to a substantial loss of economic...

This book presents an in-depth empirical analysis of consumer response to alternative policies for energy conservation. Its main focus is on innovative policy instruments that have attracted increasing attention from academics and energy conservation practitioners alike: critical peak pricing, conservation requests, in-home displays, and home energ...

This article uses panel data on how frequently households use in-home displays (IHD) in a randomized field experiment to investigate how acquiring information from IHDs affects electricity usage of households facing either dynamic pricing of electricity or conservation requests. Providing IHDs, which enables households to see a graph of their half-...

Market power in emissions trading has been extensively investigated because emerging markets for tradableemissions permits such as the European Unions Emissions Trading Scheme can be dominated by relatively fewlarge sellers or buyers. A key feature of emissions trading markets is that emissions permits are often traded bya small number of large sel...

In order to assess the effectiveness of competition policy, previous studies have extensively investigated the market power of sellers in electricity markets. The literature often assumes that the behavior of buyers is represented by the aggregate demand function, but it does not examine the market power of buyers. In the case of wholesale power ma...

This paper examines the welfare impact of emission taxes and subsidies in a green market where consumers emit a pollutant through their usage of products produced by duopolists. For this purpose, we employ a discrete–continuous model including both consumer choice and usage of an environmentally differentiated product in a utility-consistent framew...

This paper attempts to measure the benefits of information about efficient usage of electric appliances consumers receive through energy conservation, using data from a Japanese experiment. In the experiment, households could easily obtain information on how to achieve efficient usage of electric appliances through a display installed at their resi...

Reliability management of electric power systems, which used to be implemented through coordination among regulated utilities, is one of the main issues in deregulated electricity markets. The efficient management of system reliability is a crucial factor for the generation sector to be competitive because generators rely on transmission networks t...

Using a discrete-continuous model that deals with both consumers' choice and usage of an environmentally differentiated product in a utility-consistent framework, this paper investigates welfare impacts of emission taxes, subsidies and ad valorem taxes/subsidies on a green market where consumers emit a pollutant through their usage of the products...

This paper investigates the effects of alternative forms of regulation on the market penetration and capacity that are determined by a profit-maximizing monopolist providing reliability differentiated service to consumers. Both price cap and rate of return regulation lead to larger capacity and market penetration than in the absence of regulation....

This paper investigates the long-run effects of average revenue regulation on an electricity transmission monopolist who applies a two-part tariff comprising a variable congestion price and a non-negative fixed access fee. A binding constraint on the monopolist's expected average revenue lowers the access fee, promotes transmission investment, and...

This paper investigates the effects of alternative forms of regulation on the market penetration and capacity, which are determined by a profit-maximizing monopolist providing priority service to consumers. For continuous priority service, a minimum reliability standard, price cap and rate of return regulation lead to larger capacity than in the ab...

This paper conducts a welfare analysis of a two-part tariff that is applied to the congestion pricing of inputs supplied by a natural monopolist with increasing returns to scale to competitive firms that require an input in a fixed proportion to output. Congestion pricing of inputs is optimal for both the welfare-maximizing regulator and the profit...

This paper attempts to measure how information provision affects usage of consumer durables, using data on residential demand for electricity in Japan. Assuming that consumer preferences are well described by a translog indirect utility function, a discrete-continuous model of information and usage choice is estimated to examine the effects of info...

This paper measures the effects of information on residential demand for electricity, using data from a Japanese experiment. In the experiment, households had a continuous-display, electricity use monitoring device installed at their residence. The monitor was designed so that each consumer could easily look at graphs and tables associated with the...

I investigate the impacts of voluntary time-of-day (TOD) rates on residential demand for electricity. My analysis is based on a sample of a survey, which provides cross-sectional data on electricity consumption and economic/demographic features for both TOD and non-TOD households in Japan. This information is used to develop an almost ideal demand...

We measure the effect of incentive payments on residential time-of-day (TOD) electricity demand in summer, using data from a residential TOD electricity pricing experiment in the Kyushu region of southern Japan. During the experiment, participating households could receive incentive payments if they reduce their peak usage share. Results based on a...

The rapid increase in the number of electric room air conditioners (AC units) per household, which may affect summer peak demand for electricity, may be due in part to their relatively low purchase prices. The present study attempted to measure the effects of purchase prices on the household's choice of the number of AC units, using a subsample of...

This paper empirically examines customer preferences for the reliable sources of electricity using data obtained from a survey of back-up systems owned by large computer users in Japan. The empirical results based on probabilistic discrete choice models indicate that (1) customers face a trade-off between the price and the reliability of the power...

In this paper, we analyze interfuel substitution according to Japanese manufacturing sectors. We examine the impact of environmental regulations and technical changes on fuel choice, and the effects of price on fuel substitution, using pooled data on fuel consumption and purchase price for 58 regions in the period 1980-88. The empirical results, ba...

In this study an empirical analysis of Ramsey pricing in Japanese electric utilities based on the estimation results of electricity cost and demand functions was conducted. The Ramsey pricing rule, which describes the set of uniform prices maximizing the sum of producer and consumer surplus subject to the minimum profit constraint, can be directly...

"In this paper the impacts of structural changes in local industries on interregional gross migration in Japan for 1974-85 are empirically examined. Structural changes in local industries, which are represented by a simple index of local employment growth dispersion across sectors, induce interregional migration, as well as intraregional migration....

Interfuel substitution in Japanese manufacturing is discussed, using the sectoral data for energy purchase prices. Since energy end-use technology and sectoral purchase prices may be heterogeneous across sec tors, and compositional changes exist, sectoral analysis is carried out to examine interfuel substitution possibilities. The data for sectoral...

Under the low oil prices since 1986, energy demand has turned to increase and the diversification of energy sources seems decelerated in Japan. We constructed the Inter-Fuel Competition Model and examined the energy demand up to 2000 with special attention to the two aspects; whether this high growth of energy consumption is temporary or not, and h...

The Central Research Institute of Electric Power Industry (CRIEPI) has developed a multiregional econometric model covering the nine regions of Japan to analyze the impacts of the national economy and fiscal policies on the regional economy. This model is called the JNREM (Japanese Nine-region Econometric Model). The model is multi-sectoral and lin...
