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.     

Exogenous uncertainty and the identification of structural vector autoregressions with external instruments

We provide necessary and sufficient conditions for the identification (point‐identification) of structural vector autoregressions (SVARs) with external instruments considering the case in which r instruments are used to identify g structural shocks of interest, r ≥ g ≥ 1. Novel frequentist estimation methods are discussed by considering both a “partial shocks” identification strategy, where only g structural shocks are of interest and are instrumented, and a “full shocks” identification strategy, where despite g structural shocks being instrumented, all n=g+(n?g) structural shocks of the system can be identified under certain conditions. The suggested approach is applied to investigate empirically whether financial and macroeconomic uncertainty can be approximated as exogenous drivers of US real economic activity, or rather as endogenous responses to first moment shocks, or both. We analyze whether the dynamic causal effects of nonuncertainty shocks on macroeconomic and financial uncertainty are significant in the period after the global financial crisis.     

Feedback as a two-way street: when and why rating consumers fails

In efforts to keep ill-behaving consumers in check, managers are increasingly implementing the practice of rating consumers. We develop and test an account of when and why the practice of rating consumers backfires. Study 1 shows that consumers are more likely to misbehave toward service providers after receiving a low rating (versus those who receive a high rating or those who are merely aware that they are being rated). These findings are robust to consumer inexperience. The negative impact of low ratings on subsequent behavior is especially likely to emerge when directed toward consumers (versus service providers; Study 2). Study 3 situates our findings in a real-world context through a survey of Uber customers. Taken together, we offer insight into how firms can realize the benefits of the practice of rating consumers while mitigating its risks.

     

INSTITUTIONAL DETERMINANTS OF VENTURE CAPITAL ACTIVITY: AN EMPIRICALLY DRIVEN LITERATURE REVIEW AND A RESEARCH AGENDA

Venture Capital (VC) was born and has flourished in the United States, yet it has only modestly developed in other geographical areas. A vast body of research has been carried out to investigate the factors which are conducive to VC activity, and that may better explain the differences in the degree of development and performance of VC industry across different geographical contexts. However, there has only been a limited effort in the literature to systematize what we know (and what we do not know) about the institutional factors that spur VC activity. This paper tries to close that gap, through a systematic survey of the existing literature on the institutional and related determinants of VC activity. Grounding on the seminal work of North (1990), we consider formal (e.g. laws and formal rules) and informal (e.g. cultural norms and tacit codes of behaviour) institutions which are found in the extant empirical economics and management literature to affect the development of the VC industry. Building on this careful review, our paper aims to propose interesting avenues for future research in this domain.     

R&D financing and growth

ABSTRACT

R&D investment are an important engine of growth and development. Yet economists have often claimed underinvestment, based on the consideration that these projects are more costly to finance, especially, due to the asymmetric information between inside and outside investors. Coherently, a recent empirical evidence has shown that firms intensively active in R&D are less leveraged and rely more heavily on internal finance. Motivated by this evidence, we study the effects of asymmetric information and financial frictions within a GE economy of Schumpeterian tradition. The model and equilibrium concept are rich enough to represent investment and innovation decisions, technology adoption/diffusion through patent licensing and, most importantly, firms' financial decisions. In this representation, R&D-intensive firms might effectively rely more on internal sources and equity than on debt financing, relative to what would happen in frictionless markets. Further, financial decisions affect aggregate investment and income dynamics.     

Aftermarket vehicle hybridization: Potential market penetration and environmental benefits of a hybrid-solar kit

The possibility of upgrading conventional vehicles to hybrid electric vehicles has recently gained considerable interest. Among the diverse options for hybridization, researchers of the Energy and Propulsion Laboratory at the University of Salerno (Italy) have patented a system based on the electrification of the rear wheels in front-wheel-drive vehicles by adopting in-wheel motors and adding a lithium-ion battery, which is rechargeable via plug-in and solar mode. The technology integrates various components, in-vehicle Intelligent Transportation Systems and advanced on-line management algorithms. With respect to the proposed technological context, this paper uses a real case study to investigate the potential market penetration, the achievable environmental benefits and relevant policy issues. To this aim, the paper first analyses the main behavioral determinants that may affect users' perception of this new technology, then specifies and calibrates an installation choice model, and finally develops bottom-up methodology to estimate the environmental benefits to be obtained from different commercialization scenarios. The proposed methodology was applied to the city of Salerno and the achievable benefits were compared to those obtainable through the implementation of traditional transport policies.     

Seasoned equity offering announcements and the returns on European bank stocks and bonds

We analyse, by means of appropriate event studies, the returns following seasoned equity offering announcements made by western European banks between 2008 and 2014. Consistently with the pertinent literature on non-financial companies, we find that shareholders experience negative returns. We highlight that the same occurs for bondholders, although not surprisingly to a smaller extent. Overall, our results show that seasoned equity offering announcements play an important signalling role also in the banking industry, despite the tight regulation and supervision by banking authorities, which should in principle reduce the impact on pricing of the information asymmetries about banks’ financial conditions.     

Do European recommendations impact on sustainability policies by Italian local governments?

Taking the role of a facilitator, the EU has published recommendations to steer sustainability policies in local governments. The authors analysed strategic plans published by Italian local governments and found that the EU’s recommendations had zero effect. The way forward is for local governments to be required to produce sustainability policies.     

Optimal punishments in linear duopoly supergames with product differentiation

We analyze optimal penal codes in both Bertrand and Cournot supergames with product differentiation. We prove that the relationship between optimal punishments and the security level (individually rational discounted profit stream) depends critically on the degree of supermodularity in the stage game, using a linear duopoly supergame with product differentiation. The security level in the punishment phase is reached only under extreme supermodularity, i.e., when products are perfect substitutes and firms are price setters. Finally, we show that Abreu's rule cannot be implemented under Cournot behavior and strong demand complementarity between products.     

Combining random forest and copula functions: A heuristic approach for selecting assets from a financial crisis perspective

In this paper we propose a heuristic strategy aimed at selecting and analysing a set of financial assets, focusing attention on their multivariate tail dependence structure. The selection, obtained through an algorithmic procedure based on data mining tools, assumes the existence of a reference asset we are specifically interested to. The procedure allows one to opt for two alternatives: to prefer those assets exhibiting either a minimum lower tail dependence or a maximum upper tail dependence. The former could be a recommendable opportunity in a financial crisis period. For the selected assets, the tail dependence coefficients are estimated by means of a proper multivariate copula function. Copyright © 2010 John Wiley & Sons, Ltd.
