Working paper
Vinogradov D. AWI Discussion Paper Series. DP600. Heidelberg University, 2007. No. 442.
The paper examines the effects of ambiguity in regulation on the equilibrium  allocation. Under ambiguous bailout policy, agents’ suffer from a lack of information with regards to the insolvency resolution method, which would be chosen by the regulator if a financial institution fails. In this case, beliefs of bankers regarding whether an insolvent bank is liquidated, may differ from those of depositors. The beliefs may be asymmetric even if bankers and depositors possess absolutely symmetric information about the policy of the regulator. It is shown that such asymmetry in beliefs can generate an allocative inefficiency of the bank based economy.

This paper provides nested sets and vector representations of knockout tournaments. The paper introduces classification of probability domain assumptions and a new set of axioms. Two new seeding methods are proposed: equal gap seeding and increasing competitive intensity seeding. Under different probability domain assumptions, several axiomatic justifications are obtained for equal gap seeding. A discrete optimization approach is developed. It is applied to justify equal gap seeding and increasing competitive intensity seeding. Some justification for standard seeding is obtained. Combinatorial properties of the seedings are studied.

This paper surveys approaches to preference diversity measurement. Applying preference diversity axiomatics, a generalization of the Alcalde-Unzu and Vorsatz (2016) criterion, is developed. It is shown that all previously used indices violate this criterion. Two new indices (geometric mean based and leximaxbased) are developed that satisfy a new criterion. Leximax-based orders act as a polarization index and are compared with Can et al.’s (2015) polarization index. The paper concludes by formulating a new open question: the preference profile reconstruction conjecture.
