Currently no refinement exists that successfully selects equilibria across a wider range of Cheap Talk games. We propose a generalization of refinements based on credible deviations, such as neologism proofness and announcement proofness. According to our Average Credible Deviation Criterion...

We analyze sequential Dutch and Vickrey auctions where risk averse, or risk preferring, bidders may have heterogeneous risk exposures. We derive and characterize a pure strategy equilibrium of both auctions for arbitrary number of identical objects. A sufficient, and to certain extent necessary,...

In models of sequential decision making herd behaviour occurs if the signals smart(dumb) agents receive are (un)correlated and if agents have reputational concerns. We show thatintroducing costly effort to become informed about project payoffs (i) eliminates herdbehaviour and (ii) shifts...

This discussion paper resulted in a publication in the <A href="http://onlinelibrary.wiley.com/doi/10.1111/jems.12037/abstract">Journal of Economics & Management Strategy</A>. Organization differ in the degree to which they differentiate employees by ability. We analyse how the effect of differentiation on employee morale may explain this variation. By comparing...</a>
