The common approach in empirical capital structure research has been to study the determinants of optimal leverage by studying the association between observed leverage and a set of explanatory variables. This approach has two major shortcomings. First, the observed leverage need not necessarily be the optimal leverage. Second, the empirical analyses, being effectively non-dynamic, are unable t...

Analyses of the receiver operating characteristic (ROC) almost invariably suggest that, on a recognition memory test, the standard deviation of memory strengths associated with the lures (sigma(lure)) is smaller than that of the targets (sigma(target)). Often, sigma(lure)/ sigma(target) approximately = 0.80. However, that conclusion is based on a model that assumes that the memory strength dist...

Daily returns of nancial assets are frequently found to exhibit positive autocor-relation at lag 1. When specifying a linear AR(1) conditional mean, one may ask how this predictability aaects option prices. We investigate the dependence of option prices on autoregressive dynamics under stylized facts of stock returns, i.e., conditional heteroskedasticity, leverage eeect, and conditional leptoku...

This paper explores the leverage determinants across firms’ sizesbased on the two main theories behind the capital structure, the trade-offand the pecking order theories. A panel data is sued to find therelationship between capital structure and the variables that proxy forbenefits and costs of debt during 1990 to 2006. Our findings show thatboth principles help to explain the capital structure...
