Understanding others: empathy and cognitive perspective taking in the human brain

After defining “cognitive perspective taking” and “empathy” we will review the main results of neuroscientific studies of the human ability to understand other people's intentions, beliefs, and experiences. We will then present several fMRI studies investigating empathic brain responses elicited by the observation of others in pain and show how these empathic brain responses are…

This paper examines whether the chances of job placements improve if unemployed persons are counselled by caseworkers who belong to the same social group, defined by gender, age, education, and nationality. Based on an unusually informative dataset, which links Swiss unemployed to their caseworkers, we find positive employment effects of about 4 percentage points if caseworker and…

Stock options and managers’ incentives to cheat

This paper develops a continuous-time real options’ pricing model to study managers’ incentives to cheat in the presence of equity-based compensation plans. It shows that managers’ incentives to cheat are strongly influenced by the efficiency of the justice. The model’s main result is that managers have greater incentives to commit fraudulent actions under stock options than under…

Human insula activation reflects risk prediction errors as well as risk

Understanding how organisms deal with probabilistic stimulus-reward associations has been ad-vanced by a convergence between reinforcement learning models and primate physiology, which demonstrated that the brain encodes a reward prediction error signal. However, organisms must also predict the level of risk associated with reward forecasts, monitor the errors in those risk…

Antisocial Punishment Across Societies

We document the widespread existence of antisocial punishment, that is, the sanctioning of people who behave prosocially. Our evidence comes from public goods experiments that we conducted in 16 comparable participant pools around the world. However, there is a huge cross-societal variation. Some participant pools punished the high contributors as much as they punished the low…

Risk aversion when gains are likely and unlikely: evidence from a natural experiment with large stakes

In the television show Deal or No Deal a contestant is endowed with a sealed box, which potentially contains a large monetary prize. In the course of the show the contestant learns more information about the distribution of possible monetary prizes inside her box. Consider two groups of contestants, who learned that the chances of their boxes containing a large prize are 20% and 80%…

Peers and culture

We analyze the evolution of cultural traits when parents purposefully invest resources in order to socialize their children to the cultural variants that maximize child lifetime utility. We assume that children are not passive in their adoption of traits from peers. Instead they are guided by an evaluation of the merit of variants. We show that such evaluation is likely to render…

Age and choice in health insurance: evidence from a discrete choice experiment

Background: A uniform package of benefits and uniform cost sharing are elements of regulation inherent in most social health insurance systems. Both elements risk burdening the population with a welfare loss if preferences for risk and insurance attributes differ. This suggests the introduction of more choice in social health insurance packages may be advantageous; however, it is…

Limited rationality and strategic interaction: the impact of the strategic environment on nominal inertia

Much evidence suggests that people are heterogeneous with regard to their abilities to make rational, forward-looking decisions. This raises the question as to when the rational types are decisive for aggregate outcomes and when the boundedly rational types shape aggregate results. We examine this question in the context of a long-standing and important economic problem: the…

On the feasibility of insurers' investment policies

This article calls attention to a difficulty with insurers' investment policies that seems to have been overlooked so far. There is the distinct possibility that insurers cannot satisfy the demands of different stakeholders in terms of expected returns and volatility. While using the capital asset pricing model as the benchmark, this article distinguishes two groups of…

Validity and Reliability of Willingness-to-Pay Estimates: Evidence from Two Overlapping Discrete-Choice Experiments

Discrete-choice experiments, while becoming increasingly popular, have rarely been tested for validity and reliability. This contribution purports to provide some evidence of a rather unique type. Two surveys designed to measure willingness-to-accept (WTA) for reform op-tions in Swiss health care and health insurance are used to provide independent information with regard to two…

Paleopathologies of the vertebral column in medieval skeletons

Paleopathological data provide valuable information about health, longevity and mortality in earlier human populations. We investigated the incidence of spinal pathologies on 54 individuals (1045 vertebrae and 18 sacral bones) that belong to a medieval skeletal series discovered in the Dalheim monastery (Northwest Germany) and compared them with contemporary and recent populations.…

Time-resolved analysis of fMRI signal changes using Brain Activation Movies

Conventional fMRI analyses assess the summary of temporal information in terms of the coefficients of temporal basis functions. Based on established finite impulse response (FIR) analysis methodology we show how spatiotemporal statistical parametric maps may be concatenated to form Brain Activation Movies (BAMs), dynamic activation maps representing the temporal evolution of brain…

Liquidity management and overnight rate calendar effects: Evidence from German banks

We document a general pattern in the euro area overnight interbank rate (EONIA) and analyze how German banks compared to other EMU banks respond to these predictable changes in the price for reserve holdings. At the beginning of the maintenance period, when the EONIA is typically above average, we observe that German banks hold substantially less reserves than their daily average…

Consumption Risk Sharing over the Business cycle: the role of Small Firms' Access to Credit Markets

Consumption risk sharing among U.S. federal states increases in booms and decreases in recessions. We find that small firms' access to financial markets plays an important role in explaining this stylized fact: business cycle fluctuations in aggregate risk sharing are more pronounced in states in which small firms account for a large share of output. In addition, better access…

Openness, Government Size and the Terms of Trade

This paper investigates the relationship between trade openness and the size ofngovernments, both theoretically and empirically. We argue that openness can increase the size of governments through two channels: (1) a terms of trade externality, whereby trade lowers the domestic cost of taxation, and (2) the demand for insurance, whereby trade raises risk and public transfers. We…

Qualifying Religion: The Role of Plural Identities for Educational Production

This paper examines the role of religious denomination for human capital formation. We employ a unique data set which covers, inter alia, information on numerous measures of school inputs in 169 Swiss districts for the years 1871/72, 1881/82nand 1894/95, marks from pedagogical examinations of conscripts (1875-1903), andnresults from political referenda to capture conservative or…

Ensuring Financial Stability: Financial Structure and the Impact of Monetary Policy on Asset Prices

This paper studies the responses of residential property and equity prices,ninflation and economic activity to monetary policy shocks in 17 countries, using data spanning 1986-2006. We estimate VARs for individual economies and panel VARs in which we distinguish between groups of countries on the basis of the characteristics of their financial systems. The results suggest that using…
