Collateral and short squeezing of liquidity in fixed rate tenders

The paper models fixed rate tenders, where a central bank offers to lend central bank funds to financial institutions. Bidders are constrained by the amount of collateral they have. We focus on the strategic interaction between bidding in the tender and trading in the interbank market after the tender, where short squeezes could occur. We examine how the design of the tender affects…

Sobolev spaces on non-smooth domains and Dirichlet forms related to subordinate reflecting diffusions

Let Ω be a bounded domain with fractal boundary, for instance von Koch's snowflake domain. First we determine the range and the kernel of the trace on ∂Ω of Sobolev spaces of fractional order defined on Ω. This extends some earlier results of H. Wallin and J. Marschall Secondly we apply these results in studying Dirichlet forms related to subordinate reflecting diffusions in non…

Irrational entry, rational exit

This paper sets up a model for analysing the problem of rational exit where the stopping time itself is part of the integration problem. The model development is for the case of smoking. Smoking produces pleasure, pain and addiction. Our model captures all these elements and using Brownian notion and continuous martingales establishes that “quit smoking” campaigns require a two…
