Energy taxes as a signaling device: An empirical analysis of consumer preferences

Abstract [en]

This paper presents an econometric study dealing with household demand in Sweden. The main objective is to empirically examine the differences in consumer reaction to the introduction of, or the change, in environmental taxes. Main focus is on environmental taxes as asignalingdevice. The hypothesis is that the introduction of an environmental tax provides new information about the properties of the directly taxed goods. This in turn may affect consumer preferences for these goods, hence altering the consumption choice. The result from the econometric analysis shows that all goods have negative own-price elasticities, and positive income elasticities. Concerning the signalling effect of environmental taxes the results are somewhat ambiguous. The tax elasticity for energy goods used for heating seems to be significantly higher than the traditional price elasticity, whereas the opposite seems to be the case for energy goods used for transportation.

Abstract [en]

This thesis consists of four papers: two of them deal with the relationship between consumption, energy taxation, and emissions on macro level, and two of them focuses on the effects of changes in consumption and income on the environmental quality on a micro level.

The main objective of paper [I] is to examine how exogenous technological progress, in terms of an increase in energy efficiency, affects consumption choice by Swedish households and thereby emissions of carbon dioxide (CO2), sulphur dioxide (SO2) and nitrogen oxide (NOx). The aim of the paper is closely related to the discussion of what is known as the “rebound effect”. To neutralise the rebound effect, we estimate the necessary change in CO2 tax, i.e. the CO2 tax that keeps CO2 emissions at their initial level. In addition, we estimate how this will affect emissions of sulphur dioxide and nitrogen oxides. The results indicate that an increase in energy efficiency of 20 percent will increase emissions of CO2 by approximately 5 percent. To reduce the CO2 emissions to their initial level, CO2 tax must be raised by 130 percent. This tax increase will reduce the emissions of sulphur dioxide to below their initial level, but will leave the emissions of nitrogen oxides at a higher level than initially.

One of the premises implied in paper [II] is that the changes in consumer prices, as a result of changes in environmental taxes, may send a different signal to the consumer compared with other changes in consumer prices, such as changes in producer price. In addition, this assumed difference in the signaling effect of the changes in environmental taxes, compared to changes in the producer price, may also differ between different commodities. To achieve the objectives a system of demand functions for Swedish households is estimated. To test for the signalling effect of environmental taxes the consumer price for energy goods is partitioned into a producer price part and a tax part.

In Paper [III], we estimate the income elasticity of demand for recreational services and other traditional groups of goods in Sweden and we test for potential changes in such estimates over the twentieth century. The paper uses Swedish household surveys for the years 1913, 1984, 1988, and 1996. Because of the difficulty of directly observing the demand for recreational services, we employ an indirect methodology by using the demand for some outdoor goods as proxies for the recreational services demand.

In paper [IV], we investigate the relationship between pollution and income at the household level. Here we want to investigate, and hence contribute to the existing literature, under what conditions concerning individual preferences and the link between consumption and pollution a linear relationship are to be expected, but also to empirically assess the relationship. To achieve our objective we formulate a model determining different type of households’ choice of consumption for goods. Furthermore we link the demand model to emission functions for the various goods. The results from the empirical analysis show that, at least in a close neighbourhood of observed income/pollution, we can reject linearity for all three types of pollutions, CO2, SO2, and NOx. According to our results the pollution/income relationships are all strictly concave. Thus the implication is that the income distribution seems to matter in the sense that equalization of income will lead to higher emissions. Furthermore it is shown that the slope as well as the curvature differs between different types of households, which means that preferences differ across households.
