Polytope Fraud Theory (PFT) extends the existing triangle and diamond theories of accounting fraud with ten abnormal financial practice alarms that a fraudulent firm might trigger. These warning signals are identified through evaluation of the shorting behavior of sophisticated activist short...

Firms with credit-default swaps (CDS) traded on their debt may face "empty creditors'' as hedged creditors have less incentive to participate in firm restructuring. We test for the existence of empty creditors by employing an exogenous change to the bankruptcy code in Germany, that effectively...

The optimal investment-dividend policy of a financially constrained firm whose earnings are subject to additive shocks is shown to exhibit several stylized economic and financial features of the firm life cycle which usually require considerably more complex models. This parsimonious model...

This paper studies the earnings management behavior of a manager in a strategic game in which the manager may have incentives to avoid earnings below the analysts' consensus forecast and the analysts aiming to provide accurate forecasts behave as rational Bayesians. Our analysis reveals the...

Does a diversification of funding sources affect the financing conditions for firms? To answer this question we study a regulatory reform which allowed unlisted firms to issue minibonds. Using the Italian Credit Register, we compare new loans granted to issuer firms with new loans concurrently...

A large literature documents a positive correlation between a firm's sustainability or ESG policies and firm value. However, the exact mechanism through which this relation arises remains ambiguous and it is often hard to establish the direction of causation. In this paper we propose and test...

We examine the effects of mandatory ESG disclosure around the world using a novel dataset. Mandatory ESG disclosure increases the availability and quality of ESG reporting, especially among firms with low ESG performance. Mandatory ESG reporting has in turn beneficial effects on firm’s...

We study the effects of diversifying funding sources on the financing conditions for firms. We exploit a regulatory reform that took place in Italy in 2012, i.e. the introduction of ‘minibonds’, which opened a new market-based funding opportunity for unlisted firms. Using the Italian Credit...

We study an optimal dividend problem under a bankruptcy constraint. Firms face a trade-off between potential bankruptcy and extraction of profits. In contrast to previous works, general cash flow drifts, including Ornstein–Uhlenbeck and CIR processes, are considered. We provide rigorous proofs...
