Cortical plasticity of audio-visual object representations

Several regions in human temporal and frontal cortex are known to integrate visual and auditory object features. The processing of audio-visual (AV) associations in these regions has been found to be modulated by object familiarity. The aim of the present study was to explore training-induced plasticity in human cortical AV integration. We used functional magnetic resonance imaging...

Merger negotiations and ex-post regret

We consider a setting in which two potential merger partners each possess private information pertaining
both to the profitability of the merged entity and to stand-alone profits, and we investigate the extent to
which this private information makes ex-post regret an unavoidable phenomenon in merger negotiations.
To this end, we consider ex-post incentive compatible...

Influence of dopaminergically mediated reward on somatosensory decision-making

Reward-related dopaminergic influences on learning and overt behaviour are well established, but any influence on sensory decision-making is largely unknown. We used functional magnetic resonance imaging (fMRI) while participants judged electric somatosensory stimuli on one hand or other, before being rewarded for correct performance at trial end via a visual signal, at one of four...

Concurrent brain-stimulation and neuroimaging for studies of cognition

Neuroimaging can address activity across the entire brain in relation to cognition, but is typically correlative rather than causal. Brain stimulation can target a local brain area causally, but without revealing the entire network affected. Combining brain stimulation with concurrent neuroimaging allows a new causal approach to how interplay between extended networks of brain...

Lottery pricing under time pressure

This paper investigates how subjects determine minimum selling prices for lotteries. We design an experiment where subjects have at every moment an incentive to state their minimum selling price and to adjust the price if they believe that the price that they stated initially was not optimal. We observe frequent and sizeable price adjustments. We find that random pricing models can...

GPs' preferences: What price fee-for-service?

In mixed health care systems a crucial condition for the success of Managed Care (MC) plans is to win over a su±cient number of general practitioners (GPs) acting as gatekeepers. This contribution reports on GPs' willingness-to-accept (WTA) or compensation asked, respectively, for changing from conventional fee-for-service to MC practice. Some 175 Swiss GPs participated in...

Simulating WTP Values from Random-Coefficient Models

Discrete Choice Experiments (DCEs) designed to estimate willingness-to-pay (WTP) values are very popular in health economics. With increased computation power and advanced simulation techniques, random-coefficient models have gained an increasing importance in applied work as they allow for taste heterogeneity. This paper discusses the parametrical derivation of WTP values from...

This paper assesses some of the implications of globalization for the scholarly debate on business ethics, CSR and related concepts. The argument is based, among other
things, on the declining capacity of nation state institutions to regulate socially desirable corporate behavior as well as the growing corporate exposure to heterogeneous social, cultural and political values in...

Was hat die Finanzmarktkrise mit Hochschul-Rankings zu tun?

Mit der Finanzmarkt- und Wirtschaftskrise ist auch die Wirtschaftswissenschaft in eine Krise geraten. Zahlreich sind die Beiträge, die fragen, warum die »Königin der Sozialwissenschaften diese Entwicklungen nicht vorhergesehen
hat. Jenseits der simplifizierenden und wenig hilfreichen Klage der »maßlosen Gier«, welche es zu bekämpfen gelte,
werden vor allem zwei...

Two are better than one!: individuals' contributions to "unpacked" public goods

We experimentally demonstrate how "unpacking" provides a possible approach for mitigating the dilemma of public goods provision through private contributions. Subjects' total contributions increase when a single public good is split into two identical public goods.

Financial globalisation and securitisation in mortgage markets

Mortgage-backed securities have played a major role in the financial crisis and aren’t very popular as a result. This column documents macroeconomic benefits of these instruments, showing that economies with more developed markets for securitised mortgage debt share more consumption risk with other economies.

The unrecognized future dimension of corporate sustainability assessment

Companies play a central role on the way towards sustainable development. Over the last years, many approaches have emerged that attempt to measure companies’ contribution to sustainable development, i.e. corporate sustainability. Our analysis of existing approaches reveals two major shortcomings. First, value creation as a core condition for sustainability as well as for further...

Local deformation of extraocular muscles during eye movement

Purpose. To study extraocular muscle (EOM) function, the local physiologic contraction and elongation (deformation) along human horizontal EOMs were quantified using motion-encoded MRI. Methods. Eleven subjects (healthy right eye) gazed at a target that moved horizontally in a sinusoidal fashion (period 2s, amplitude +/-20 degrees ), during MR imaging with an optimized protocol. In...
