Income Satisfaction Inequality and Its Causes
In this paper, the concept of Income Satisfaction Inequality is operationalized on the basis of individual responses to an Income Satisfaction question posed in the German Socio-Economic Panel (GSOEP). Income satisfaction is the subjective analogue of the objective income concept and includes objective income inequality as a special case. The paper introduces a method to decompose Income Satisfaction Inequality according to the contributions from variables such as income, education, and the number of children. Given the panel structure of the data, inequality may be attributed partly to permanent individual circumstances and partly to transitory changes. The paper shows that by far the largest part of the satisfaction inequality has to be ascribed to unobserved heterogeneity. Distinguishing between a structural and an unexplained part of inequality we find that income explains the largest part of structural Income Satisfaction Inequality together with household membership; for non-working individuals, the age distribution is very relevant as well.Equivalent Income, Financial Satisfaction, Income Satisfaction, Income Inequality, Variance Decomposition.
The Subjective Costs of Health Losses Due to Chronic Diseases: An Alternative Model for Monetary Appraisal
This paper proposes a method to evaluate health losses or gains by looking at the impact on well-being of a change in health status. The paper presents estimates of the equivalent income change that would be necessary to change general satisfaction with life to the same extent as a change in health satisfaction would do. In other words, we estimate the income equivalent of health changes. Next, the health satisfaction changes are linked to specific diseases in order to estimate the income equivalent for various diseases. This method uses answers to well-being and health satisfaction questions as posed in a large German data set. We distinguish between workers and non-workers and between inhabitants of East- and West- Germany. We find, for instance, that for West-workers hearing impediments are on average equivalent to an income reduction of about 20%, and that heart blood difficulties are for the same group equivalent to a 47% income reduction.chronic diseases, equivalent income, health damages, health satisfaction, well-being.
ab inito local vibrational modes of light impurities in silicon
We have developed a formulation of density functional perturbation theory for
the calculation of vibrational frequencies in molecules and solids, which uses
numerical atomic orbitals as a basis set for the electronic states. The
(harmonic) dynamical matrix is extracted directly from the first order change
in the density matrix with respect to infinitesimal atomic displacements from
the equilibrium configuration. We have applied this method to study the
vibrational properties of a number of hydrogen-related complexes and light
impurities in silicon. The diagonalization of the dynamical matrix provides the
vibrational modes and frequencies, including the local vibrational modes (LVMs)
associated with the defects. In addition to tests on simple molecules, results
for interstitial hydrogen, hydrogen dimers, vacancy-hydrogen and
self-interstitial-hydrogen complexes, the boron-hydrogen pair, substitutional
C, and several O-related defects in c-Si are presented. The average error
relative to experiment for the aprox.60 predicted LVMs is about 2% with most
highly harmonic modes being extremely close and the more anharmonic ones within
5-6% of the measured values.Comment: 18 pages, 1 figur
Tuning the electrical conductivity of nanotube-encapsulated metallocene wires
We analyze a new family of carbon nanotube-based molecular wires, formed by
encapsulating metallocene molecules inside the nanotubes. Our simulations, that
are based on a combination of non-equilibrium Green function techniques and
density functional theory, indicate that these wires can be engineered to
exhibit desirable magnetotransport effects for use in spintronics devices. The
proposed structures should also be resilient to room-temperature fluctuations,
and are expected to have a high yield.Comment: 4 pages, 6 figures. Accepted in Physical Review Letter
The Anatomy of Subjective Well-Being
Subjective Well-Being has increasingly been studied by several economists. This paper fits in that literature but takes into account that there are different aspects of life such as health, financial situation, and job. We call them domains. In this paper, we consider Subjective Well-Being as a composite of various domain satisfactions (DS). We postulate a two -layer model where individual Subjective Well-Being is explained by individual subjective domain satisfactions with respect to job, finance, health, leisure, housing, and environment. We distinguish between long -term and short - term effects. Next, we explain domain satisfactions and Subjective Well-Being by objectively measurable variables such as income. We estimate a model for the GS and DS equations with individual random effects and fix time effects.Subjective Well-Being, satisfaction measurement, qualitative regressors, health satisfaction, job satisfaction
Happiness and Financial Satisfaction in Israel: Effects of Religiosity, Ethnicity, and War
We analyze individual satisfaction with life as a whole and satisfaction with the personal financial situation for Israeli citizens of Jewish and Arab descent. Our data set is the Israeli Social Survey (2006). We are especially interested in the impact of the religions Judaism, Islam and Christianity, where we are able to differentiate between individuals who vary in religiosity between secular and ultra-orthodox. We find a significant effect of religiosity on happiness. With respect to Jewish families it is most striking that the impact of family size on both life and financial satisfaction seems to vary with religiosity. This might be a reason for differentiation in family equivalence scales. For Arab families we did not find this effect. First-generation immigrants are less happy than second-generation immigrants, while there is no significant difference between second-generation families and native families. The effect of the Lebanon War is much less than expected.religion, Israel, financial satisfaction, subjective well-being, happiness, immigration, terrorism
Synthesis of Barbaralones and Bullvalenes Made Easy by Gold Catalysis
The gold(I)-catalyzed oxidative cyclization of 7-ethynyl-1,3,5-cycloheptatrienes gives 1-substituted barbaralones in a general manner, which simplifies the access to other fluxional molecules. As an example, we report the shortest syntheses of bullvalene, phenylbullvalene, and disubstituted bullvalenes, and a readily accessible route to complex cage-type structures by further gold(I)-catalyzed reactions
Effects of Bose-Einstein Condensation on forces among bodies sitting in a boson heat bath
We explore the consequences of Bose-Einstein condensation on
two-scalar-exchange mediated forces among bodies that sit in a boson gas. We
find that below the condensation temperature the range of the forces becomes
infinite while it is finite at temperatures above condensation.Comment: 10 pages, 2 figure
