Temporal activation patterns of lateralized cognitive and task control processes in the human brain

In a recent fMRI study with identical word stimuli we demonstrated task-dependent lateralization of brain activity during visual processing, with left-hemispheric activations for letter decisions and right-hemispheric activations for visuospatial decisions (Stephan, K.E.,
Marshall, J.C., Friston, K.J., Rowe, J.B., Ritzl, A., Zilles, K., Fink, G.R., 2003. Lateralized Cognitive…

Personal trust between hierarchies within Chinese organizational settings

With the fast pace of globalization and knowledge-driven economy, the notion of trust in intra- and/or trans-organizational relations has attracted enormous attention both in academic research and business practices. It has been recognized that trust as a central mechanism
within and between organizations plays a crucial role for economic performance. Trust relationship at…

Assessing and managing operational risk with a special emphasis on terrorism risk

The objective of this thesis is to consider different risk
management issues in relation to operational risk with a special emphasis on terrorism risk. Our motivation to implement research in this particularly challenging area of risk management is due to the increasing magnitude of operational losses over the last decade and their negative effect on financial industry. This…

I feel how you feel but not always: the empathic brain and its modulation

The ability to share the other’s feelings, known as empathy, has recently become the focus of social neuroscience studies. We review converging evidence that empathy with, for example, the pain of another person, activates part of the neural pain network of the empathizer, without first hand pain stimulation to the empathizer’s body. The amplitude of empathic brain responses is…

The lack of international consumption risk sharing: can inflation differentials and trading costs help explain the puzzle?

The bulk of evidence on the lack of international risk sharing is based on regressions of idiosyncratic consumption growth on idiosyncratic output growth. This paper argues that the results from such regressions obtained from international data are, however, not directly comparable to those based on regional data: the standard practice of running such regressions on international…

Range Effects and Lottery Pricing

A standard method to elicit certainty equivalents is the Becker-DeGroot-Marschak (BDM) procedure. We compare the standard BDM procedure and a BDM procedure with a restricted range of minimum selling prices that an individual can state. We find that elicited prices are systematically affected by the range of feasible minimum selling prices. Expected utility theory cannot explain these…

Probabilistic Choice and Stochastic Dominance

This paper presents an axiomatic model of probabilistic choice under risk. In this model, when it comes to choosing one lottery over another, each alternative has a chance of being selected, unless one lottery stochastically dominates the other. An individual behaves as if he compares lotteries to a reference lottery—a least upper bound or a greatest lower boundnin terms of weak…

Central Bank Design with Heterogeneous Agents

We study alternative institutional arrangements for the determination of monetary policy in a general equilibrium model with heterogeneous agents,nwhere monetary policy has redistributive effects. Inflation is determined by a policy board using either simple-majority voting, supermajority voting, ornbargaining. We compare the equilibrium inflation rates to the first-best allocation…

Effects of Firm Size and Business Cycle on Earning Losses of Displaced Workers

This paper analyzes labor market success of workers who are displaced in boom versus recession periods. Moreover, the empirical analysis contrasts workers from small firms and large firms. The idea is that displacement carries no information about workers' productivity in large firms but is a signal of low productivity in small firms. This signal is stronger when the plant…

The Value of a Statistical Injury: New Evidence from the Swiss Labor Market.

This paper deals with the compensation for non-fatal accident risk in Switzerland and presents empirical estimates of the value of a statistical injury. We approach the problem of endogenous sorting of workers into jobs with different accident risks based on unobserved productivity differences twofold. First, we have access to the number of accidents not only at the level of…

The Power of Positional Concerns

People care a great deal about their relative economic position and not solely about their absolute economic position. However, behavioral evidence is rare. This paper provides evidence on how the relative income position affectsnprofessional sports performances. Our analysis suggests that if a player’s salary is below the average and this difference increases, his performance…

Risk Aversion

Risk aversion is traditionally defined in the context of lotteries over monetary payoffs. This paper extends the notion of risk aversion to a more general setup where outcomes (consequences) may not be measurable in monetary terms and people may have fuzzy preferences over lotteries, i.e. they may choose in a probabilistic manner. The paper considers comparative risk aversion within…

Valuation of default-sensitive claims under imperfect information

We propose a valuation method for financial assets subject to default risk, where investors cannot observe the state variable triggering the default but observe a correlated price process. The model is sufficiently general to encompass a large class of structural models and can be seen as a generalization of the model of Duffie and Lando (Econometrica 69:633–664, [2001]). In this…

Exports, Foreign Direct Investment and the Costs of Corporate Taxation

Depending on the definition of the tax base, the statutory corporate tax rate implies rather different measures of effective average and marginal tax rates. This paper develops a model of a monopolistically competitive industry with extensive and intensive business investment and shows how these margins respond to changes in average and marginal corporate tax rates. Intensive…

Sustainability of Swiss Fiscal Policy

We examine whether Swiss federal fiscal policy was sustainable over the period from 1900 to 2002. We perform unit root and cointegration tests for federal revenues and expenditures, taking into account a structural shift in the budgetary process related to World War II. We find sustainability over the entire period. However, splitting the sample into two sub-samples before and after…
