Jan - Willem Romeijn Conditioning and Interpretation Shifts

This paper develops a probabilistic model of belief change under interpretation shifts, in the context of a problem case from dynamic epistemic logic. Van Benthem [4] has shown that a particular kind of belief change, typical for dynamic epistemic logic, cannot be modelled by standard Bayesian conditioning. I argue that the problems described by van Benthem come about because the belief change ...

This paper presents experimental results generated through a program of shake-table testing of simple frames through collapse. Fifteen four-column frame specimens were subjected to progressive unidirectional ground shaking as structural response was measured. The specimens were subdivided into groups of three different column slenderness ratios: 100, 150, and 200. Within each group, column dime...

Speculative Trade under Ambiguity ∗ Jan

Ambiguous beliefs may lead to speculative trade and speculative bubbles. We demonstrate this by showing that the classical Harrison and Kreps (1978) example of speculative trade among agents with heterogeneous beliefs can be replicated with agents having common ambiguous beliefs. More precisely, we show that the same asset prices and pattern of trade can be obtained in equilibrium with agents’ ...
