Collaborator or competitor: assessing the evidence supporting the role of social enterprise in health and social care

In many countries, social enterprise has been introduced into a competitive market-oriented environment as a substitute for publicly owned services, particularly in healthcare. In the United Kingdom, evidence for this move seems to derive from case studies where social enterprise operates in collaboration – as opposed to competition – with publicly owned services. Our systematic review demonstrates that there is no evidence to support the role of social enterprise as a substitute for publicly owned services. However, there is evidence to show that where social enterprise operates in a collaborative environment, enhanced outcomes can be achieved, such as connectedness, well-being and self-confidence.     

Fast and accurate calculation of American option prices

We propose a very efficient numerical method to solve a nonlinear partial differential problem that is encountered in the pricing of American options. In particular, by using the front-fixing approach originally developed in Wu and Kwok (J Financ Eng 6:83–97, 1997) and Nielsen et al. (J Comput Finance 5:69–97, 2002) in conjunction with a suitable change of the time variable, a (nonlinear) partial differential problem is obtained which can be solved very efficiently by means of a finite difference scheme enhanced by repeated Richardson extrapolation. Numerical results are presented showing that the novel algorithm yields excellent results, and performs significantly better than a finite different method with Bermudan approximation.     

Examining the effect of novelty seeking,satisfaction, and destination image on tourists’ return pattern: A two factor,non-linear latent growth model

With many destinations relying on repeat business, intention to revisit has become an important research topic. As revisit intention changes over time, this paper proposes the use of a latent growth curve to model the developmental trajectory of return behavior. The proposed model was tested in two steps in AMOS 16.0 using SEM methodologies to investigate the effects of novelty seeking, destination image and overall satisfaction levels across intent to revisit trajectories using data collected among French, English, and German travelers. Findings indicate that both novelty seeking and low satisfaction among travelers temper immediate intent to return. Conversely, a positive image of the destination enhances both immediate and future intentions to return.     

Productivity Shocks and Labour Market Outcomes for Top Earners: Evidence from Italian Serie A

How are top earners affected by productivity shocks? We address this question using a unique longitudinal data set on the universe of professional football players in the Italian Serie A, representing 20% of top earners in Italy. We use traumatic injuries and adopt an IV strategy to provide causal estimates of the impact of productivity shocks on several labour market outcomes. We find that a 30-day injury substantially affects the probability of contract renegotiation and reduces net wages by around 12%. We show that this large penalty is due to employer's precautionary motives rather than to shock-induced reduction in current player's performance.     

Exploring the effects of mergers and acquisitions on acquirers' sustainability orientation: Embedding,adding, or losing sustainability

Mergers and acquisitions (M&A) have been primarily investigated from a shareholder-centric perspective of economic value maximization. However, this type of strategic initiatives also carries relevant implications for companies' capacity to respond to increasing social and environmental concerns among their stakeholders. In this study, we explore the processes related to, and nonfinancial consequences of, acquisitions involving sustainability-oriented firms. Leveraging interviews with business decision makers and secondary data covering the pre- and post-acquisition phases, we find three main paths leading the acquiring firms to embed, add, or lose sustainability. Therefore, three possible post-acquisition outcomes emerge, associated with differences in acquirers' focus on sustainability infusing the deal rationale, their due diligence activity, and practices of stakeholder management and integration in the post-acquisition phase.     

Genetic distance,trade, and the diffusion of development

The determinants of countries' long‐term income differences feature prominently in the literature. Spolaore and Wacziarg (The diffusion of development, Quarterly Journal of Economics, 2009 , 124, 469–529) argue that cultural differences, measured by countries' genetic distance, are an important barrier to the diffusion of development from the world's technological frontier. We revisit their findings in three ways. First, we successfully reproduce their results and confirm the robustness of their baseline findings. Second, we estimate their models for different time periods and find that the impact of genetic distance on income differences did not significantly change over time. Finally, we explore one of the underlying mechanisms of technology adoption and show that bilateral trade is one channel through which cultural differences retard the diffusion of development.     

Valuing investment projects under interest rate risk: empirical evidence from European firms

In this article, we perform an empirical investigation of the effect of the interest rate uncertainty on the valuation of investment projects. The analysis is carried out by employing a real option approach and by considering a set of firms that operate in various production sectors in the euro area. In particular, the revenues generated by the investment projects are modelled using a geometric Brownian motion, whereas the interest rate is specified as a stochastic process of Vasicek type. Moreover, using the volatility of the equity return as a proxy, the volatility of the revenues is calibrated to real firm data, while the parameters of the interest rate model are estimated by fitting the Euribor time series. To this aim, an ad hoc calibration procedure is developed which is based on the maximum likelihood principle and thus has the merit of being simple, fast and suitable for practical purposes. Our study reveals that the interest rate uncertainty reduces the valuation of investment projects. However, stochastic interest rates do not provide a substantial improvement with respect to constant interest rates, or at least the differences are not statistically significant.     

Policy commitment and the welfare gains from capital market liberalization

This paper evaluates the quantitative impact of capital liberalization on the taxation structure and welfare of the liberalizing countries when governments conduct fiscal policy optimally but without commitment (time-consistent policies). The transition from a regime of capital autarky to a regime of free mobility leads to a decrease in the long-term tax rate on capital of 13 percent and an increase in the tax rate on labor of 2 percent. As a consequence of this taxation shift, welfare increases by about 1 percent. The reduction in capital taxation induced by capital market liberalization is welfare improving because, in the absence of capital mobility, the time-consistent policies over-tax capital.
