We propose a nonparametric method to determine the functional form of the noise density in discrete-time stochastic volatility models of financial returns. Our approach suggests that the assumption of Gaussian noise is often adequate, but we do observe deviations from Gaussian noise for some...

We derive microscopic foundations for a well-known probabilistic herding model in the agent-based finance literature. While the model is quite robust with respect to behavioral heterogeneity, the network structure describing the very feasibility of agent interaction turns out to have a crucial...

A growing body of literature reports evidence of social interaction effects in survey expectations. In this note, we argue that evidence in favor of social interaction effects should be treated with caution, or could even be spurious. Utilizing a parsimonious stochastic model of expectation...

From a statistical point of view, the prevalence of non-Gaussian distributions in nancial returns and their volatilities shows that the Central Limit Theorem (CLT) often does not apply in nancial markets. In this paper we take the position that the independence assumption of the CLT is violated...

We consider the current bipartite graph of German corporate boards and identify a small core of directors who are highly central in the entire network while being densely connected among themselves. To identify the core, we compare the actual number of board memberships to a random benchmark,...

We investigate experimentally the modification of initial chances to acquire advantaged positions in bargaining problems. In the baseline case players have equal opportunities to acquire the advantaged position. Chances become increasingly unequal across three treatments. We find: (1) The more...

There is an old saying that states that “If the United States sneezes, the rest of the world catches a cold”. Against this background, it is argued that some countries, especifically China, can “decouple” from the US economy and sustain strong growth in the face of a US slowdown. In this...

While it has been long recognized that active management represents an important issue related to mutual fund performance, little has been agreed about the value added by managers from their abilities point of view. This study attempts to explore both fund and manager characteristics in order to...

Over the last 15 years, the evolution of labor costs has been very diverse across EMU countries. Since wages have important second-round effects on prices and competitiveness, and EMU countries do not have the tool of the nominal exchange rate to correct for such imbalances, understanding the...

We revisit the sequential search problem by Hey (1987). In a 2x2 factorial design, varying fixed and random cost treatments with and without recall, we address open research questions that were originally stated by Hey (1987). Our results provide clear evidence for Hey’s (1987) conjecture that...
