The Instability of the Money Demand Function: An I(2) Interpretation

Some studies have suggested that although money and prices appear to be I(2) processes, real money balances are I(1) and this transformation preserves an important long-run relationship between money and prices. In this paper we present evidence indicating that the success of such a nominal-to-real transformation depends upon the particular monetary aggregate under consideration. It turns out that imposing long-run price homogeneity does not remove all I(2) components from a model of aggregate broad UK M4, but it does prove successful in the case of sectoral components of M4. Since recent research on money demand functions finds more stable relationships between sectoral components of M4 and aggregate demand, our analysis seems to point to a direct link between the existence of I(2) components and the stability of different money demand functions.     

The ‘Whys’ and ‘Hows’ of ethical investment: Understanding an early-stage market through an explorative approach

Over the last decade, markets for investments have changed in Europe. Consumers have become more aware of ethical standards and violations of social values and norms. While in some countries, such as the United States, this change took place decades ago, the market for ethical investment in Europe is still at an early stage. The present study investigates the underlying motives for ethical assets of consumers in early-stage markets. Using seven interviews with financial experts and five focus groups with ethical and conventional investors, we examine how investors view ethical investment, how ethical investors are described in terms of socio-demographics and personality characteristics, and which attitudinal factors are related to ethical investment behaviour. Interviews and focus groups are recorded and qualitatively analysed according to grounded theory. Ethical investment is found to be characterised through negative and positive ethical criteria. Our findings demonstrate how essential it is for ethical investors to lead a certain lifestyle driven by particular ecological and social values. Attitude theory serves to explain ethical investment behaviour. Conclusions for the marketing of ethical investment funds and for future research are drawn.     

Do Lower Caseloads Improve the Performance of Public Employment Services? New Evidence from German Employment Offices

The caseworker‐to‐clients ratio is an important, but understudied, policy parameter that affects both the quality and cost of public employment services that help job seekers find employment. We exploit a large‐scale pilot by Germany's employment agency, which hired 490 additional caseworkers in 14 of its 779 offices. We find that lowering caseloads caused a decrease in the rate and duration of local unemployment as well as a higher re‐employment rate. Disentangling the mechanisms that contributed to this improvement, we find that offices with lowered caseloads increased monitoring and imposed more sanctions but also intensified search efforts and registered additional vacancies.     

Approximating Large Diversified Portfolios

This paper considers a financial market with asset price dynamics modeled by a system of lognormal stochastic differential equations. A one‐dimensional stochastic differential equation for the approximate evolution of a large diversified portfolio formed by these assets is derived. This identifies the asymptotic dynamics of the portfolio as being a lognormal diffusion. Consequentially an efficient way for computing probabilities, derivative prices, and other quantities for the portfolio are obtained. Additionally, the asymptotic strong and weak orders of convergence with respect to the number of assets in the portfolio are determined.     

Stabilising Citizen and Consumer Expectations by Legal Means when Introducing the Euro in the Participating Member States

The author discusses the introduction of the euro from a consumer law point of view. The paper refers to the report of the Euro Working Group of the EC Consumer Committee. Dual indication of prices, continuity of contracts, costs, and transparency are discussed and solutions suggested. The recommendations recently adopted by the EC Commission have taken up some of these points but the proposals are far from satisfactory.     

Neue tendenzen des kartellrechtlichen verbraucherschutzes in der BRD

In German consumer protection, antitrust law is playing an increasingly prominent role. This article informs about the problems of protecting consumers against monopolizing pricing practices. It also discusses the law of recommended prices. The author suggests that substantive reforms of the antitrust law are necessary in order to improve the position of the consumer.

Neue tendenzen des kartellrechtlichen verbraucherschutzes in der BRD

Zusammenfassung Für den Schutz des Verbrauchers in der Bundesrepublik gewinnt das Kartellrecht zunehmende Bedeutung. Der Beitrag stellt dies an den Problemen der Preiskontrolle gegenüber marktbeherrschenden Unternehmen und des Preisempfehlungsrechtes dar. Der Autor verficht hier die These, daß im Zuge der Novellierung des Kartellrechtes auch Vorschriften zur Verbesserung des Verbraucherschutzes erforderlich und möglich sind.

Consumer response to child tax credit

This article uses micro-level data from the Consumer Expenditure Survey (CEX) to study consumers?? spending responses to the child tax credit. The article provides one test of the permanent-income hypothesis (PIH) that infers that temporary changes in income have little effect on consumer spending, at the initiation of the child tax credit in 1997, and a second PIH test when the credit was increased in 2003. The evidence supports the PIH in both 1997 and 2003, even using three different proxies for liquidity-constrained households. Separate from any PIH implications, our findings suggest the child tax credit did not provide a short-term consumption stimulus in either of the time periods studied. Our results therefore cast some doubt on whether this type of tax credit should be considered sound fiscal policy.
