Wer ist von Altersarmut bedroht?

Which groups have particularly low pension entitlements and are therefore most at risk of poverty in old age? Participation in the labour force for some individuals may be interrupted for a variety of reasons, including education, unemployment, raising children or caring for relatives, all of which result in low pensions. Those who are most at risk of poverty in old age are individuals with low earnings, frequent or long periods of unemployment, and single, unemployed mothers. In other words, those impoverished while young are most likely to remain impoverished into old age. Poverty among the elderly should therefore be addressed with the same instruments with which poverty is being fought in earlier stages of life, rather than through changes in the statutory pension insurance system.     

CARBON REDUCTION COSTS IN NEW ENGLAND'S POWER SECTOR

This paper examines the cost of reducing carbon emissions in New England's power sector. The analysis relies on detailed sectoral studies of costs and resource potentials for demand-side efficiency, cogeneration, renewables, and conventional resource options. Sectoral studies' results were integrated using a production-cost model to estimate the total cost and rate impacts of carbon reduction strategies relative to a business-as-usual forecast. To capture potential uncertainties, the analysis takes into account variations in capital costs, fuel prices, resource utilization levels, and base case retirements of existing power plants. Results show that New England's power sector can freeze carbon emissions at current levels or reduce carbon emissions while simultaneously decreasing customers' total electricity bills.     

Time Consistent Collection of Optimal Seigniorage: A Unifying Framework

This paper reviews the existing literature on the time consistency problem of seigniorage collection when monetary policy is determined by optimal taxation considerations. It develops a unifying accounting framework and suggests a general measure for seigniorage, which encompasses the standard measures employed in the literature. In addition, the ex ante optimal solution to the optimal taxation problem is derived and interpreted in relation to the Ramsey principle. We show that the different recommendations of the public finance literature, i.e. the Friedman rule of optimal deflation, [moderately] positive inflation, and seigniorage maximizing inflation, are specific solutions to the optimal taxation problem. The paper continues with a formal illustration of the time consistency problem of the ex ante optimal policy and the characterization of the time consistent solution under discretion. As possible solutions to the time consistency problem, we consider reputational forces, institutional reforms that establish central bank independence, and specific ways of asset and debt management. In particular, it is formally shown that a modified version of the asset and debt management scheme suggested by Persson, Persson, and Svensson is not only necessary but also sufficient for optimality, although this did not hold in their model.     

Strategische Steuerung der betrieblichen Gesundheitsförderung mit Strategy Maps

Zusammenfassung  Der vorliegende Beitrag widmet sich der Steuerung und Bewertung von Ma?nahmen der betrieblichen Gesundheitsf?rderung. Gesellschaftliche Ver?nderungen wie bspw. die Globalisierung oder der demografische Wandel führen dazu, dass die Gesundheit der Mitarbeiter in vielen Bereichen zu einem Engpassfaktor der Leistungserstellung geworden ist. Eine zentrale Rolle zur gezielten unternehmerischen Beeinflussung der personellen Ressourcen eines Unternehmens und damit auch der Gesundheit der Mitarbeiter spielt das Wissen über Ursache-Wirkungsbeziehungen im Bereich der betrieblichen Gesundheitsf?rderung und deren Einfluss auf den Erfolg der Leistungserstellung. Zur gezielten Steuerung der betrieblichen Gesundheitsf?rderung wird ein Rahmenkonzept vorgestellt, das aus der Logik der Balanced Scorecard und Strategy Maps abgeleitet wird und auf Ursache-Wirkungsbeziehungen basiert.
