Consider a non-spanned security CT in an incomplete market. We study the risk/return tradeoffs generated if this security is sold for an arbitrage-free price bC0 and then hedged. We consider recursive “one-period optimal” self-financing hedging strategies, a simple but tractable criterion....

We study a firm's debt-maturity policy. The firm, keeping book leverage constant, rolls over expiring debt by newly issuing short- or long-term bonds, which pay different coupons. In equilibrium, we always find two balanced issuance regimes, which are associated with one type of debt: In bad...

We study a rich dynamic-leverage model that includes (debt-issuance covenants, a debt floor/ceiling, and specially) a fixed cost. When firms face financial but also operational leverage---the fixed cost, the firm's financial policies strongly interact---bringing forward the default time but...

Purpose: Counterfeiting is a menace in the emerging markets and many successful brands are falling prey to it. Counterfeit brands not only deceive consumers but also fuel a demand for lower priced replicas, both of which can devalue the bona-fide brand. But can consumers accurately identify a...

We assume that some consistent estimator of an equilibrium relation between non-stationary fractionally integrated series is used in a first step to compute residuals (or differences thereof). We propose to apply the semiparametric log-periodogram regression to the (differenced) residuals in...

We consider statistical inference in the presence of serial dependence. The main focus is on use of statistics that are constructed as if no dependence were believed present, and are asymptotically normal in the presence of dependence. Typically the variance in the limit distribution is affected...

This article proposes goodness-of-fit tests for dynamic regression models, where regressors are allowed to be only weakly exogenous and arbitrarily correlated with past shocks. The null hypothesis is stated in terms of the lack of serial correlation of the errors of the model. The tests are...
