Ownership ties,conflict of interest,and the tone of news

This paper investigates the tone newspapers use in reporting information on a company that it is linked with through an ownership tie. Our empirical setting is Italy, a country characterized by dominant national industrial groups’ high ownership of newspapers. Based on a sample of about 123,000 articles, we document that newspapers’ coverage of firms in conflict of interest is greater, with significantly fewer negative and uncertain words. We also document that the slant increases with ownership stakes and decreases with the newspaper's reputation.     

The role of time value in convertible bond call policy

Since the seminal work of Ingersoll (1977b) the optimal time in which a firm should redeem its outstanding convertible bonds has received large attention by the financial literature. Several studies have put forward a number of possible costs and benefits for a firm if it interrupts the life of its convertible bonds prior to their contractual maturity. However, in this paper we argue that the managerial decision to call back a convertible bond is mainly driven by a fundamental variable almost neglected up until now: the time value extraction from bondholders’ conversion option. Accordingly, we propose a measure for the effective convenience of calling—which we define as net time value advantage—and we show, using a survival analysis, that it is more effective than previously proposed measures in explaining the firms’ observed call policy.     

Uncertainty across volatility regimes

We propose a nonrecursive identification scheme for uncertainty shocks that exploits breaks in the volatility of macroeconomic variables and is novel in the literature on uncertainty. This approach allows us to simultaneously address two major questions in the empirical literature: Is uncertainty a cause or effect of decline in economic activity? Does the relationship between uncertainty and economic activity change across macroeconomic regimes? Results based on a small‐scale vector autoregression with US monthly data suggest that (i) uncertainty is an exogenous source of decline of economic activity, and (ii) the effects of uncertainty shocks amplify in periods of economic and financial turmoil.     

Endogenous debt maturity and rollover risk

We empirically study the nature of rollover risk and show how banks manage it. Having to roll over debt does not lead to higher default risk per se. Only banks that lose significant access to new funding while having to roll over debt display higher default risk. We identify a factor that determines this buildup of risk: specifically, debt maturity shortening (forcing debt to be more frequently rolled over) and reduced access to new funding are both driven by market pessimism about banks’ future performance. We also provide evidence consistent with dynamic coordination risk.     

What’s up after brain drain? Sometimes, somewhere, someone comes back: a general model of return migration

Individual preferences and wage differentials are generally interpreted as determinants of agents?? migration decisions in search of job opportunities. Literature about migration flows usually describes both theoretical and empirical evidence for either temporary or permanent movements of workers, but brain drain migration has its own peculiar characteristics. This paper aims to obtain two results: the first is to present the law of determination that leads to the moment of the return decision, and the second is to analyse how the difference between the utility from domestic and foreign consumption evolves in time. The presented model explains how the return decision is determined, even in cases when the agent does not leave or does not return at all.     

Testing the purchasing power parity through I(2) cointegration techniques

This paper contributes to the empirical literature on the purchasing power parity (PPP) over the post‐Bretton Woods period by providing a time‐series based interpretation of the controversial evidence characterizing the dynamics of real exchange rates. It is shown that the persistence of deviations from the PPP between a set of European countries and the United States may be empirically attributed to the presence of I(2) stochastic trends in prices using Consumer Price Indices. Interestingly, the slow adjustment towards the equilibrium can be modelled through ‘integral‐proportional’ equilibrium correction models and this evidence can be partly reconciled with theories where the inflation rate reduces the markup of profit‐maximizing firms acting on imperfectly competitive markets.

Conversation with secrets

We analyze the sustainability of a conversation when one agent might be endowed with a piece of private information that affects the payoff distribution to its benefit. Such a secret can compromise the sustainability of conversation. Even without an obligation, the secret holder will disclose its secret if it prevents preemptive termination of the conversation. The nonsecret holder lacks this possibility and stops the conversation. Competition and limited effectiveness of the conversation amplify this result of early disclosure and render the conversation process less sustainable. We discuss policy and managerial implications for industry standard development and joint ventures.     

A generalized approach to optimal hedging with option contracts

In this paper, we develop a theoretical model in which a firm hedges a spot position using options in the presence of both quantity (production) and basis risks. Our optimal hedge ratio is fairly general, in that the dependence structure is modeled through a copula function representing the quantiles of the hedged position, and hence any quantile risk measure can be employed. We study the sensitivity of the exercise price which minimizes the risk of the hedged portfolio to the relevant parameters, and we find that the subjective risk aversion of the firm does not play any role. The only trade-off is between the effectiveness and cost of the hedging strategy.
