In this paper we analyze the security of the compression function of SHA-1 against collision attacks, or equivalently free-start collisions on the hash function. While a lot of work has been dedicated to the analysis of SHA-1 in the past decade, this is the first time that free-start collisions have been considered for this function. We exploit the additional freedom provided by this model by u...

Existing research links CEO personality traits to a number of corporate decisions including overinvestment, external acquisitions, and earnings management. These findings raise the question of whether counterparties distinguish between differences in individual CEO behavior, and how they respond to it. We focus on two key counterparties – auditors and credit rating agencies – and examine whethe...

Although the long-term perspective, strategic turning ...
