Estimating the profits from trading strategies

Price improvement is the difference between the execution priceof an order and the quoted bid or ask when the order was submitted.We show that expected price improvement falls off dramaticallyas the size of the order approaches the quoted depth, and becomesnegative for larger orders. This is particularly important forsmall firms because the quoted depths are low. Using quotedspreads and depths and our estimate of expected price improvement,we show that trading strategies that attempt to exploit theweekly predictability of small-firm returns would be swampedby transaction costs.     

Further evidence on the international business cycle and the ERM: is there a European business cycle?

Successful exchange rate regimes impose policy disciplines thatare likely to lead to conformity in the business cycles of theparticipating countries. This conjecture is borne out in thepaper by the evidence in it that the business cycle affiliationof ERM member countries has shifted from the United States toGermany since the formation of the ERM. This effect is bolsteredby the growing links in trade between the EU countries. TheUnited Kingdom is conspicuous among the latter in that its businesscycle affiliation did not change in the period covered by thestudy.
