Abstract

In the theory of weakly hyperbolic equations we have the effect of loss of regularity. The present paper devotes to the study of two problems. On the one hand we describe families of weakly hyperbolic Cauchy problems for which we have no loss of regularity. On the other hand we discuss the question if the loss of derivatives really appears.

Recent work on the 'size effect' suggests that size-related regularities in asset prices (such as size, leverage, book to market equity, etc.) should not be regarded as anomalies. This paper first clarifies the argument (by showing why the OLS cross-section regression incorporating size-related vari
