Central Bank Collateral Frameworks

This paper seeks to inform about a feature of monetary policy that is largely overlooked, yet occupies a central role in modern monetary and financial systems, namely central bank collateral frameworks. Their importance can be understood by the observation that the money at the core of these systems, central bank money, is injected into the economy on terms, not defined in a market,...

Dopamine D2-receptor blockade enhances decoding of prefrontal signals in humans

The prefrontal cortex houses representations critical for ongoing and future behavior expressed in the form of patterns of neural activity. Dopamine has long been suggested to play a key role in the integrity of such representations, with D2-receptor activation rendering them flexible but weak. However, it is currently unknown whether and how D2-receptor activation affects prefrontal...

Ursachen von Preisvolatilität auf Agrarmärkten

Was sind die Ursachen hoher Preisvolatilität auf den globalen Agrarmärkten? In der öffentlichen Diskussion wird oft die «Finanzialisierung» des Agrarhandels für die stark schwankenden Nahrungsmittelpreise verantwortlich gemacht. Dabei wird übersehen, dass Preisbewegungen primär auf Veränderungen der Verfügbarkeit von global handelbaren Nahrungsmitteln zurückzuführen sind. Diese...

A polynomial optimization approach to principal-agent problems

This paper presents a new method for the analysis of moral hazard principal-agent problems. The new approach avoids the stringent assumptions on the distribution of outcomes made by the classical first-order approach and instead only requires the agent's expected utility to be a rational function of the action. This assumption allows for a reformulation of the agent's...

Generosity across contexts

Extensive research in economics explores generosity in monetary allocations. However, generosity often involves the allocation of non-monetary goods or experiences. Existing evidence suggests that generosity may be higher in such contexts, though no direct comparison exists. Here, we compare generosity in decisions that vary whether allocations are monetary or non-monetary. In two...

Apathy but Not diminished expression in schizophrenia is associated with discounting of monetary rewards by physical effort

Negative symptoms in schizophrenia have been grouped into the 2 factors of apathy and diminished expression, which might be caused by separable pathophysiological mechanisms. Recently, it has been proposed that apathy could be due to dysfunctional integration of reward and effort during decision making. We asked whether apathy in particular is associated with stronger devaluation (...

The role of bounded rationality and imperfect information in subgame perfect implementation: an empirical investigation

In this paper we conduct a laboratory experiment to test the extent to which Moore and Repullo's subgame perfect implementation mechanism induces truth-telling in practice, both in a setting with perfect information and in a setting where buyers and sellers face a small amount of uncertainty regarding the good's value. We find that Moore-Repullo mechanisms fail to implement...

Decentralized matching and social segregation

Social segregation is a ubiquitous feature of human life. People segregate along the lines of income, religion, ethnicity, language, and other characteristics. This study provides the first experimental examination of decentralized matching with search frictions and institutionalized segregation. The findings indicate that, without a segregation institution, high types over-segregate...

Long-term Relationships: Static Gains and Dynamic Inefficiencies

Do contractual frictions matter when firms are engaged in repeated interactions? This paper argues that long-term relationships, which allow firms to (partly) overcome the static costs associated with low contractibility, will under certain circumstances create dynamic inefficiencies. We consider the repeated interaction between final good producers and intermediate input suppliers,...

Taking Banks to Solow

We develop a simple integration of banks into the Solow model. The objective is to provide a tractable benchmark for analyzing the long-term impact of crises on economic activities and growth. A fraction of firms have to rely on banks for financing their investments while banks face themselves an endogenous leverage constraint. Informed lending by banks and uninformed lending through...

Anticipatory anxiety disrupts neural valuation during risky choice

Incidental negative emotions unrelated to the current task, such as background anxiety, can strongly influence decisions. This is most evident in psychiatric disorders associated with generalized emotional disturbances. However, the neural mechanisms by which incidental emotions may affect choices remain poorly understood. Here we study the effects of incidental anxiety on human...

Automatic versus choice-dependent value representations in the human brain

The subjective values of choice options can impact on behavior in two fundamentally different types of situations: first, when people explicitly base their actions on such values, and second, when values attract attention despite being irrelevant for current behavior. Here we show with functional magnetic resonance imaging (fMRI) that these two behavioral functions of values are...

Making Sustainable Strategy in Complex Management Environments: Proposition for a Systemic and Practice-Oriented Methodology

The increasing complexity of the modern world creates both higher risks and new interdependencies in the socioeconomic environment. To cope with these challenges powerful new tools must be applied to find sustainable solutions. System dynamics is a field that offers potential assistance in dealing with complex issues. However, managers and politicians often lack the knowledge and...

Quantification and characteristics of household inflation expectations in Switzerland

Inflation expectations are a key variable in conducting monetary policy. However, these expectations are generally unobservable and only certain proxy variables exist, such as surveys on inflation expectations. This article offers guidance on the appropriate quantification of household inflation expectations in the Swiss Consumer Survey, where answers are qualitative in nature. We...
