We study the link between underpricing of initial public offerings (IPOs) and index excess returns in secondary markets. We use a theoretical model to argue that underpricing of IPOs raises investors’ attention and, thereby, triggers investments in secondary markets. Our theoretical model...

We study return predictability of stock indexes of blue chip firms and smaller hightechnology firms in Germany, France, and the United Kingdom during the second half of the 1990s. We measure return predictability in terms of first-order autocorrelation coefficients, and find evidence for return...

I use a time-varying parameter model in order to study the predictability of monthly real stock returns in Germany over the period 1880–1913. I find that the extent to which returns were predictable underwent significant changes over time. Specifically, predictability of returns, as measured...

A large market economy has a huge number of degrees of freedom with weak microlevel coordination. The implicit microfoundations' approach assumes this property of micro-level interactions more strongly conditions macro-level outcomes compared to the precise details of individual choice behavior;...

This paper studies the concept of an international economic order, i.e. an institutional arrangement of international rules. Such rules emerge from negative experiences – historical disasters – that inflict severe hardship on people. A taxonomy for rules reducing transaction costs is...

We show how time-dependent macroeconomic response follows from microeconomic dynamics using linear response theory and a time-correlation formalism. This theory provides a straightforward approach to time-dependent macroeconomic model construction that preserves the heterogeneity and complex...

In this paper, we explore a dynamical version of by Aoki and Yoshikawa model (AYM) for an economy driven by demand. We show that when an appropriate Markovian dynamics is taken into account, AYM has di¤erent equilibrium distributions depending on the form of transition probabilities. In the...

This paper analyzes how international rules are established and stabilized, i.e. how an international institutional order develops. Rules emerge mainly through learning from negative experience and serve to reduce transaction costs. The paper looks at mechanisms that stabilize rule systems, at...

The paper explores utility measures by combining experiments with mathematical derivations in psychophysics paradigm. The analysis on ultimatum game experiment reveals an evidence for utility threshold and thus supports Bernoulli's utility logarithmic law. Both experimental results and...
