    This paper investigates the effect of unemployment on earnings for ten European countries. Using an harmonised database (ECHP), we estimate the impact of declared unemployment on individuals while taking account of attrition and unobserved individual heterogeneity. We find that the unemployment effect differs by country and gender. The wage penalty is greater for men than for women. It is also higher in the more flexible economies. We suggest that labour market institutions such as unemployment benefits and wage-setting institutions may be avenues of investigation to explain these differences.Unemployment, Unobserved heterogeneity, post unemployment earnings.

    Back Reaction and Semiclassical Approximation of cosmological models coupled to matter

    Get PDF
    Bianchi -I, -III, and FRW type models minimally coupled to a massive spatially homogeneous scalar field (i.e. a particle) are studied in the framework of semiclassical quantum gravity. In a first step we discuss the solutions of the corresponding equation for a Schr\"odinger particle propagating on a classical background. The back reaction of the Schr\"odinger particle on the classical metric is calculated by means of the Wigner function and by means of the expectation value of the energy-momentum-tensor of the field as a source. Both methods in general lead to different results.Comment: 4 pages, Latex, to appear in: Proceedings of the Second Meeting on constrained Dynamics and Quantum Gravity (Santa Margherita Ligure 1996

    Correspondence in Quasiperiodic and Chaotic Maps: Quantization via the von Neumann Equation

    Full text link
    A generalized approach to the quantization of a large class of maps on a torus, i.e. quantization via the von Neumann Equation, is described and a number of issues related to the quantization of model systems are discussed. The approach yields well behaved mixed quantum states for tori for which the corresponding Schrodinger equation has no solutions, as well as an extended spectrum for tori where the Schrodinger equation can be solved. Quantum-classical correspondence is demonstrated for the class of mappings considered, with the Wigner-Weyl density ρ(p,q,t)\rho(p,q,t) going to the correct classical limit. An application to the cat map yields, in a direct manner, nonchaotic quantum dynamics, plus the exact chaotic classical propagator in the correspondence limit.Comment: 36 pages, RevTex preprint forma

    Gold mineralisation in the Surselva region, Canton Grisons, Switzerland

    The Tavetsch Zwischenmassif and neighbouring Gotthard Massif in the Surselva region host 18 gold-bearing sulphide occurrences which have been investigated for the present study. In the Surselva region, the main rock constituting the Tavetsch Zwischenmassif (TZM) is a polymetamorphic sericite schist, which is accompanied by subordinate muscovite-sericite gneiss. The entire tectonic unit is affected by a strong vertical schistosity, which parallels its NE-SW elongation. The main ore minerals in these gold occurrences are pyrite, pyrrhotite and arsenopyrite. The mineralisation occurs in millimetric stringers and veinlets, everywhere concordant with the schistosity. Native gold is present as small particles measuring 2-50ÎŒm, and generally associated with pyrite. Average grades are variable, but approximate 4-7g/t Au, with several occurrences attaining 14g/t Au. Silver contents of the gold are on the order of 20wt%. A "bonanza” occurrence consists of a quartz vein coated by 1.4kg of native gold. The origin of the gold is unknown. On the assumption that the sericite schists are derived from original felsic volcanic tuffs, the gold-bearing sulphides may have been introduced during pre-Alpine magmatis

    The cantatas of Johann Ludwig Bach

    Thesis (Ph.D.)--Boston UniversityThe purpose of the investigation of Johann Ludwig Bach's seventeen liturgical cantatas and the "Trauermusik" was to establish their position within the historic development of the German sacred cantata between the seventeenth and eighteenth centuries, to study their stylistic and formal characteristics, and to present an objective picture of the work of this generally unknown cousin of Johann Sebastian Bach. The study of these works was made from microfilms of the original manuscripts now in the libraries of Berlin and Marburg. Texts and chorale melodies were traced through examination of the Bible, collections of sacred poetry, hymnals, and chorale melody collections. Works of a similar character by contemporary composers were analytically examined for comparison and to help place Johann Ludwig's compositions in the overall historic development of the cantata form. Historical and documentary data were obtained from numerous literary sources dating form the early eighteenth century to the present. [Truncated

    Take a different look: how concrete and abstract mindsets affect individuals' judgments and decisions

    Get PDF
    Taking a different look or a new perspective, studying a problem from afar or close up can affect individuals’ judgment and decision-making. Construal Level Theory argues that depending on whether individuals construe on a more abstract (higher) versus more concrete (lower) level, they will attend to different pieces of information, which may result in different outcomes. This dissertation builds on Construal Level Theory and uncovers open questions concerning judgments of truth, diversity, dishonesty, and the use of decision-making aids. It aims at offering answers to these questions, which have so far not been considered from a Construal Level Theory perspective. Jaffé and Greifeneder (2017) find that the negativity bias regarding judgments of truth might attenuate or even reverse under high compared to low construal level. Looking at diversity, Jaffé, Rudert, and Greifeneder (2017) show that individuals might appreciate working with a dissimilar other under high construal level, but prefer a more similar counterpart under low construal level. Looking at dishonest behavior, Jaffé, Greifeneder, and Reinhard (2017) highlight that Machiavellianism has a stronger impact under high compared to low construal level. Finally, Jaffé, Reutner, and Greifeneder (2017) look at decision-making aids and provide support for the notion that a simple device like a coin flip might catalyze decisions, allowing for more affect-driven decisions where individuals might have been undecided before. In sum, the research projects of this dissertation advance our knowledge in regards to how and in which contexts abstract and concrete mindsets affect individuals’ judgments and decisions
