Nominal or Real? The Impact of Regional Price Levels on Satisfaction with Life
According to economic theory, real income, i.e., nominal income adjusted for purchasing power, should be the relevant source of life satisfaction. Previous work, however, has only studied the impact of inflation adjusted nominal income and not taken into account regional differences in purchasing power. Therefore, we use a novel data set to study how regional price levels affect satisfaction with life. The data set comprises about 7 million data points that are used to construct a price level for each of the 428 administrative districts in Germany. We estimate pooled OLS and ordered probit models that include a comprehensive set of individual level, time-varying and time-invariant control variables as well as control variables that capture district heterogeneity other than the price level. Our results show that higher price levels significantly reduce life satisfaction. Furthermore, we find that a higher price level tends to induce a larger loss in life satisfaction than a corresponding decrease in nominal income. A formal test of neutrality of money, however, does not reject neutrality of money. Our results provide an argument in favor of regional indexation of government transfer payments such as social welfare benefits
Functional Renormalization Group and the Field Theory of Disordered Elastic Systems
We study elastic systems such as interfaces or lattices, pinned by quenched
disorder. To escape triviality as a result of ``dimensional reduction'', we use
the functional renormalization group. Difficulties arise in the calculation of
the renormalization group functions beyond 1-loop order. Even worse,
observables such as the 2-point correlation function exhibit the same problem
already at 1-loop order. These difficulties are due to the non-analyticity of
the renormalized disorder correlator at zero temperature, which is inherent to
the physics beyond the Larkin length, characterized by many metastable states.
As a result, 2-loop diagrams, which involve derivatives of the disorder
correlator at the non-analytic point, are naively "ambiguous''. We examine
several routes out of this dilemma, which lead to a unique renormalizable
field-theory at 2-loop order. It is also the only theory consistent with the
potentiality of the problem. The beta-function differs from previous work and
the one at depinning by novel "anomalous terms''. For interfaces and random
bond disorder we find a roughness exponent zeta = 0.20829804 epsilon + 0.006858
epsilon^2, epsilon = 4-d. For random field disorder we find zeta = epsilon/3
and compute universal amplitudes to order epsilon^2. For periodic systems we
evaluate the universal amplitude of the 2-point function. We also clarify the
dependence of universal amplitudes on the boundary conditions at large scale.
All predictions are in good agreement with numerical and exact results, and an
improvement over one loop. Finally we calculate higher correlation functions,
which turn out to be equivalent to those at depinning to leading order in
epsilon.Comment: 42 pages, 41 figure
What (If Anything) Do Satisfaction Scores Tell Us About the Intertemporal Change in Living Conditions?
This paper looks at the information content of satisfaction scores. It is argued that the information content depends on the extent to which people adapt to living conditions in general. Using data from the German Socio-Economic Panel Study (SOEP), the estimation of a dynamic panel data model provides evidence that adaptation takes place within a relatively short window of time: changes in living conditions are, for the most part, absorbed by an adjustment of the adaptation level within one year. This leads to the conclusion that the information content of satisfaction scores accentuates recent changes in living conditions. Remote changes are notcaptured by the according survey questions, even if these changes have long-term impact on living conditions. The usefulness of satisfaction scores as an indicator of people's living conditions is discussed
Digital Work Design
Erworben im Rahmen der Schweizer Nationallizenzen (http://www.nationallizenzen.ch)More and more academic studies and practitioner reports claim that human work is increasingly disrupted or even determined by information and communication technology (ICT) (Cascio and Montealegre 2016). This will make a considerable share of jobs currently performed by humans susceptible to automation (e.g., Frey and Osborne 2017; Manyika et al. 2017). These reports often sketch a picture of ‘machines taking over’ traditional domains like manufacturing, while ICT advances and capabilities seem to decide companies’ fate. Consequently, ICT is often put at the core of innovative efforts. While this applies to nearly all areas of workplace design, a recent popular example of increasing technology centricity is ‘Industry 4.0’, which is often delineated as ‘machines talking to computers’
Concerns about the Euro and happiness in Germany during times of crisis
This empirical study investigates if people's concerns about the euro currency affect their life satisfaction. A minority of very concerned individuals appear to be unhappy, which cannot be explained by personality or other observable factors typically affecting well-being. As a novelty, this investigation exploits exogenous variation in reported concerns by using the intensity of media coverage on the euro crisis with its extraordinary events throughout the year 2011 as an instrument. Results from the application of several empirical approaches confirm that there is an effect from being concerned about the euro on people's satisfaction with life. The first potential explanation is that perceived economic insecurity works as a transmission channel, but this is not fully supported by the empirical evidence. A second explanation suggests that political beliefs and euro-skeptic attitudes are at play and may trigger unhappiness as a consequence of a perceived lack of representation in German politics. In line with this argument, a regional analysis links the variation in unhappiness among concerned citizens to the actual votes for Germany's first major anti-euro party in the subsequent federal elections
Search for time-dependent B0s - B0s-bar oscillations using a vertex charge dipole technique
We report a search for B0s - B0s-bar oscillations using a sample of 400,000
hadronic Z0 decays collected by the SLD experiment. The analysis takes
advantage of the electron beam polarization as well as information from the
hemisphere opposite that of the reconstructed B decay to tag the B production
flavor. The excellent resolution provided by the pixel CCD vertex detector is
exploited to cleanly reconstruct both B and cascade D decay vertices, and tag
the B decay flavor from the charge difference between them. We exclude the
following values of the B0s - B0s-bar oscillation frequency: Delta m_s < 4.9
ps-1 and 7.9 < Delta m_s < 10.3 ps-1 at the 95% confidence level.Comment: 18 pages, 3 figures, replaced by version accepted for publication in

Employed But Still Unhappy? On the Relevance of the Social Work Norm
In the modern welfare state, people who cannot make a living usually receive financial assistance from public funds. Accordingly, the so-called social work norm against living off other people is violated, which may be the reason why the unemployed are so unhappy. If so, however, labour market concepts based on the notion of promoting low-paid jobs that are subsidised if necessary with additional payments would appear far less favourable. It could be that people are employed, but still unhappy. Using German panel data, this paper examines the relevance of the social work norm and finds a significant disutility effect of living off public funds. Although this is true for employed people as well, the results show that the individual is generally better off having a job that requires additional assistance, than having no job at all. On the other hand, such policies as the recent German labour market reforms can trigger undesired side-effects, if policy-makers ignore the issue of the social work norm
Measurement of the branching ratios of the Z0 into heavy quarks
We measure the hadronic branching ratios of the Z0 boson into heavy quarks:
Rb=Gamma(Z0->bb)/Gamma(Z0->hadrons) and Rc=Gamma(Z0->cc/Gamma(Z0->hadrons)
using a multi-tag technique. The measurement was performed using about 400,000
hadronic Z0 events recorded in the SLD experiment at SLAC between 1996 and
1998. The small and stable SLC beam spot and the CCD-based vertex detector were
used to reconstruct bottom and charm hadron decay vertices with high efficiency
and purity, which enables us to measure most efficiencies from data. We obtain,
Rb=0.21604 +- 0.00098(stat.) +- 0.00073(syst.) -+ 0.00012(Rc) and, Rc= 0.1744
+- 0.0031(stat.) +- 0.0020(syst.) -+ 0.0006(Rb)Comment: 37 pages, 8 figures, to be submitted to Phys. Rev. D version 2:
changed title to ratios, used common D production fractions for Rb and Rc and
corrected Zgamma interference. Identical to PRD submissio
