Understanding of consumer behaviour as a prerequisite for environmental protection

A number of the environmental problems threatening our habitat are to a greater or lesser extent caused by present consumer lifestyles. More sustainable lifestyles cannot be obtained without marked changes in consumer attitudes and consumer behaviour. To arrive at a synthesis of what is known, and of what needs to be known, about the determinants of consumer behaviour with an environmental impact, a frame of reference employing three main classes of variables is used: motivation, ability, and opportunity. Apart from surveying the research of others, illustrations are given from studies carried out by the group of researchers at the Aarhus School of Business to which the authors belong; this research has been mainly concerned with waste handling and recycling. In addition, various strategies for changing consumer behaviour in an environment-friendly direction are considered. Information, moral arguments, and economic incentives are discussed as instruments for change. In setting goals for change strategies, broad goals such as heightened psychic and communicative activity in matters of environmental concern ought to be considered as an alternative to the elicitation of very specific behaviours.

Zusammenfassung Einsicht in das Vehalten von Konsumenten als Voraussetzung für den Schutz derZahlreiche Umweltprobleme, die unsere Lebensgrundlagen bedrohen, werden Umwelt. mehr oder weniger von den Lebensgewohnheiten der Konsumenten verursacht. Lebensstile, die demgegenüber eher als nachhaltig gelten können, könen nur durch deutliche Veränderungen im Bereich der Einstellungen und des Verhaltens von Konsumenten erzielt werden.Der Beitrag liefert eine Zusammenschau dessen, was über die Einflu\faktoren auf das Verbraucherverhalten bekannt ist, soweit es Umweltwirkungen hat, und zeigt ebenso auf, was dazu noch nicht bekannt ist. Als Bezugsrahmen wählt er ein Modell, das Merkmale auf den drei Ebenen Motivation, Fähigkeit und Möglichkeit unterscheidet.Au\er einem überblick über Forschungsergebnisse, die in der Literatur berichtet werden, schildert der Beitrag auch Ergebnisse der Forschergruppe an der Aarhus School of Business, zu der die beiden Autoren des Beitrages gehören. Diese Ergebnisse beziehen sich in erster Linie auf Abfallverhalten und Wiederverwertung.Schlie\lich werden verschiedene Strategien zur Veränderung des Verbraucherverhaltens in umweltfreundlicher Richtung behandelt, vor allem Informationen, moralische Argumente und ökonomische Anreize. Bei der Formulierung von Zielen für solche Veränderungen sollten breite Zielsetzungen, wie z.B. gesteigerte psychische und kommunikative Aktivität in Umweltangelegenheiten, als Alternative zur Erreichung sehr spezifischen Verhaltens erwogen werden.

     

The demand for broad money in Norway, 1969–1993

Cointegration analysis is applied to investigate the long run relationships between money, prices, and wages in Norway. Broad money is determined endogenously, and monetary balances were exposed to large shocks during the period of financial deregulation in the midst of the 1980s. In the long run these shocks are absorbed, and a long run demand for money relationship is identified in which real money is determined by real income, the relative price on financial assets (the yield spread) and the relative price on goods (the own real interest rate). Money adjusts dynamically to changes in the exchange rate and private wealth. Domestic price inflation is affected by improted inflation including currency depreciation (a pass through effect), domestic cost pressure (unit labour costs), and excess demand in the product market (output gap effect).This paper was presented at the workshop Money Demand in Europe, at the Humboldt University in Berlin, October 10–11, 1997.

A COMMENT ON “ESTIMATING DYNAMIC DISCRETE CHOICE MODELS WITH HYPERBOLIC DISCOUNTING” BY HANMING FANG AND YANG WANG

Fang and Wang's (2015) Proposition 2 claims generic identification of a dynamic discrete choice model with hyperbolic discounting under exclusion restrictions. We note that Proposition 2 uses a definition of “generic” that does not preclude that a generically identified model is nowhere identified. We provide two examples of models that are generically identified under this definition, but that are, respectively, everywhere and nowhere identified. We then show that the proof of Proposition 2 is incorrect and incomplete. We conclude that Proposition 2 has no implications for identification of the dynamic discrete choice model and suggest alternative approaches to its identification.     

Intergenerational Earnings Mobility Revisited: Estimates Based on Lifetime Earnings*

Using Norwegian intergenerational data, which include a substantial part of the life‐cycle earnings for children and almost the entire life‐cycle earnings for their fathers, we present new estimates of intergenerational mobility. Extending the length of fathers’ earnings window from 5 to 25 years increases estimated elasticities. Increasing the age at which fathers’ earnings are observed has the opposite effect. Biases in the estimated elasticities are related to both transitory earnings variation and life‐cycle measurement error; the former appear to be more important than the latter. Estimation bias stemming from persistence in transitory innovations plays only a minor role. Our findings indicate that intergenerational earnings mobility in Norway might have been strongly overstated in many earlier studies with shorter earnings histories. Some of our new estimates are twice as large as earlier estimates.     

Estimating the returns to schooling: a likelihood approach based on normal mixtures

In this paper we develop likelihood‐based methods for statistical inference in a joint system of equations for the choice of length of schooling and earnings. The model for schooling choice is assumed to be an ordered probit model, whereas the earnings equation contains variables that are flexible transformations of schooling and experience, with corresponding coefficients that are allowed to be heterogeneous across individuals. Under the assumption that the distribution of the random terms of the model can be expressed as a finite mixture of multinormal distributions, we show that the joint probability distribution for schooling and earnings can be expressed on closed form. In an application of our method on Norwegian data, we find that the mixed Gaussian model offers a substantial improvement in fit to the (heavy‐tailed) empirical distribution of log‐earnings compared to a multinormal benchmark model.

The dynamics of regional specialization and cluster formation: dividing trajectories of maritime industries in two Norwegian regions

The theoretical starting point of this paper is the academic debate on regional specialization, agglomeration and industrial clusters. The paper offers further insights into the industrial dynamics within regional contexts by combining two approaches: (1) an historical study of industrial agency focusing on entrepreneurship, diversification and specialization; (2) a study of the relations within contemporary industrial systems important for industrial upgrading. Methodical triangulation has provided longitudinal studies. Particular attention is paid to path dependence as well as entrepreneurial capacity in order to explain why the industrial trajectories of matching regions divide. As the paper discusses continuity and change, a more dynamic perspective on path dependency is introduced. The past is not just regarded as a constraint, but as heritage as well. The dynamics leading to cluster formation and upgrading as well as industrial fragmentation are investigated in detail. The developments of shipyards and related maritime industries of the two Norwegian regions compared are characterized by static continuity and dynamic continuity, respectively.     

On generic vs. brand promotion of farm products in foreign markets

Farm groups and their governments spend millions of dollars each year advertising agricultural products in international markets. Intuitively, country-of-origin or ‘brand’ advertising should be more profitable than generic advertising in that it enhances product differentiation and reduces free riding. However, unlike generic advertising, brand advertising decreases the demand for competing imports and lowers their prices when supplies are upward sloping. In addition to inviting retaliation, the decline in the prices of competing products erodes the price of the advertised product through second-round or ‘market feedback’ effects. In this study, we develop a generalized model for assessing the relative effectiveness of generic and brand promotion in the international market when products are differentiated by source origin and supplies are uncontrolled. Applying the model to US beef promotion in Japan, we find that when brand and generic advertising are equally efficient in the sense that they cause equivalent horizontal shifts in the group and product-specific demand curves, generic advertising is indeed more profitable for most of the relevant parameter space. Distributional analysis suggests that, with equal export supply elasticities, the gross benefits of generic advertising are distributed across exporters in proportion to the expenditure elasticities for the products in question.     

Reforming social security: assessing the effects of alternative funding strategies

Population ageing implies that the large pay-as-you-go social security programmes implemented in many OECD economies will run into severe financial problems. By means of a numerical overlapping generations model, this paper investigates the intergenerational welfare effects of a transition to funded security programmes. Such programmes imply permanent increases in the welfare of the young and unborn generations. It is demonstrated that the size of the welfare gains varies significantly between alternative funding strategies. A nonindividualized funding strategy characterized by increased government asset accumulation triggers considerable welfare gains through increased asset returns in the future. Even larger welfare gains may be realized by an individual funding strategy characterized by increased asset accumulation accompanied by an adoption of actuarial supplementary pensions (i.e. actuarial supplementary pensions combined with a fixed minimum pension) which reduces future tax distortions drastically.     

GROSS AND NET CAPITAL, AND THE FORM OF THE SURVIVAL FUNCTION: THEORY AND SOME NORWEGIAN EVIDENCE

In this paper we discuss the empirical measurement of capital stocks derived from data on gross investment. Two capital concepts are involved: gross capital-representing the capital's capacity dimension-and net capital–representing its wealth dimension. A brief summary of their components is presented.
The data base consists of long series of Norwegian national accounts data for gross investment at a disaggregated level of sector classification and for 1–3 capital categories within each sector. Survival functions, representing the process of retirement and decline in efficiency of capital units over time, with different curvature (concave, convex) and non-zero interest rates for the discounting of future capital service flows are considered. The effects of these parameters on the calculated gross and net capital stocks in the years 1956–82 as well as on the implied replacement and depreciation rates and rates of return are discussed.
