Cyclic shifts of the van der Corput set
In [13], K. Roth showed that the expected value of the discrepancy of
the cyclic shifts of the point van der Corput set is bounded by a constant
multiple of , thus guaranteeing the existence of a shift with
asymptotically minimal discrepancy, [11]. In the present paper, we
construct a specific example of such a shift.Comment: 12 page
Firm performance and managerial turnover: the case of Ukraine
The paper studies whether and how CEO turnover in Ukrainian firms is related to their performance. Based on a novel dataset covering Ukrainian joint stock companies in 2002-2006, the paper finds statistically significant negative association between the past performance of firms measured by return on sales and return on assets, and the likelihood of managerial turnover. While the strength of the turnover-performance relationship does not seem to depend on factors such as managerial ownership and supervisory board size, we do find significant entrenchments effects associated with ownership by managers. Overall, our analysis suggests that corporate governance in Ukraine operates with a certain degree of efficiency, despite the well-known lacunas in the country’s institutional environment
