Exchange option pricing under stochastic volatility: a correlation expansion

Efficient valuation of exchange options with random volatilities while challenging at analytical level, has strong practical implications: in this paper we present a new approach to the problem which allows for extensions of previous known results. We undertake a route based on a multi-asset generalization of a methodology developed in Antonelli and Scarlatti (Finan Stoch 13:269–303, 2009) to handle simple European one-asset derivatives with volatility paths described by Ito’s diffusive equations. Our method seems to adapt rather smoothly to the evaluation of Exchange options involving correlations among all the financial quantities that specify the model and it is based on expanding and approximating the theoretical evaluation formula with respect to correlation parameters. It applies to a whole range of models and does not require any particular distributional property. In order to test the quality of our approximation numerical simulations are provided in the last part of the paper.     

Acquisitions and CEO power: Evidence from French networks

During mergers and acquisitions, the CEOs of the acquiring firms are likely to cancel the deal if the market does not react favorably to its announcement. Using a sample of French acquisition announcements during the period from 2000 to 2005, this paper studies the conditions in which CEOs are more willing to listen to investors. Furthermore, according to the strong networks developed through French elite schools' alumni and board ties, the well-connected CEOs are more likely to complete any deal in spite of a negative market reaction to acquisition announcements.     

Accounting and governance in the final years of the Papal States: Dual roles in the papacy of Pius IX (1846–1870)

The Papal States represent a unique and long period in Italian government and in the government of the Roman Catholic Church prior to Italy's unification in 1870. The 25-year period prior to unification was a particularly tumultuous period when the Papal States struggled for survival, faced military and popular challenges and became increasingly indebted. Accounting could become an important tool to assist decision-making and enhance the Papal States' sustainability, as shown by the governance reforms promulgated by Pope Pius IX in this period. Nevertheless, accountants chose what to make visible and emphasised secular, rather than the sacred aspects of the Papal States. Despite reforms, there was a disconnection between the leaders and the accountants. This research therefore examines the role of accounting in such an institution, and extends the concept of a sacred-secular divide to a state government beset by resource constraints and challenged to fulfil its spiritual aims.     

ORGANIZATIONAL CHANGE,SKILL FORMATION,HUMAN CAPITAL MEASUREMENT: EVIDENCE FROM ITALIAN MANUFACTURING FIRMS

Abstract This paper emphasizes the role of labour demand as a determinant of human capital formation. After a section in which the alternative conceptions on the functioning of labour markets are presented and different ways of measuring human capital are compared, an applied analysis is carried out in which we provide a labour‐demand‐oriented measure of human capital, as defined by the amount of specific skills firms generate through work‐based training (WBT) activities. By merging three rich firm‐level datasets, we estimate the impact of a set of variables supposed to affect both the propensity to invest in WBT and the intensity of training within the Italian manufacturing industry over the period 2001–2005. Special attention is devoted to the variables characterizing within‐firm organization of knowledge, organizational change and the formation of competence pipelines: among them, innovation, internationalization commitment, out‐sourcing and new hirings. The estimates show that the effect of innovation on WBT is higher when the introduction of new technologies is supported by organizational innovations. When looking at the nature of WBT, we investigate the different determinants of the firms' propensity to provide both in‐house and outside training. We measure training intensity in terms, respectively, of the number of provided training activities, private and total training costs and share of trainees.     

Pay-As-You-Drive Angebote von Erstversicherern für Privatkunden

“Pay-as-you-drive” (PAYD) concepts for car liability insurances envisage that real driving behavior and situation data are captured and processed via car sensors and tracking systems in order to calculate case-specific insurance rates which better correspond to the risk profiles of policy holders (PH) than conventional tariffs. The present article provides an outline of PAYD insurance variants, of legal arrangements with particular relevance for PAYD offerings in Germany and of the international dissemination of PAYD concepts. It shows that although PAYD offerings of direct insurers (DI) for private customers are not barred by insurmountable technical or legal barriers, they so far have little practical relevance in Germany. Against this background expected PAYD impacts on revenues and costs of DI are discussed in detail in order to analyze the extent to which DIs’ cautious PAYD offering strategies may be qualified as economically reasonable. The investigation suggests that the profitability effects of PAYD insurances of DI targeted at private customers are far from being definitely and clearly positive. Thus, it is very unlikely that DI will make significant investments on their own in order to create a large German residential market for PAYD insurances. Rather such a market will not emerge without accompanying state interventions.     

Modeling hedge fund exposure to risk factors

This paper examines the adjustment dynamics of hedge fund returns and studies their exposure to risk factors in a nonlinear framework for several types of strategies over the last two decades. Nonlinearity is justified by distortions due to the use of short selling, leverage, derivatives and illiquid assets for hedge fund strategies. Among nonlinear models, switching regime (STR) models are applied to reproduce the dynamics of hedge fund returns. This nonlinear multivariate modeling has the advantage of capturing the time-varying exposure of hedge fund strategies to risk factors, and of specifying the asymmetric relationship between hedge fund returns and risk. The findings are interesting and provide several contributions to the hedge fund literature. First, we show that the dynamics of hedge fund returns exhibit significant asymmetry and nonlinearity, indicating that they evolve and vary asymmetrically in accordance with stages in financial cycles. Second, hedge fund exposure to risk factors also varies over time, depending on the strategy and the regime. Finally, our modeling captures the most important changes in hedge fund exposure to risk factors induced by the recent global financial crisis (2008–2009).     

Localized Technological Change and Unemployment in the Global Economy: a Schumpeterian approach

This paper develops a Schumpeterian approach to analyse the interaction between unemployment and localized technological change in a global competitive process. The model predicts that the present levels of unemployment are caused by a combination of three factors: (i) the localized character of the wave of information and communication technology generated in the more advanced countries which, because of this, it is characterized by a factor mix appropriate to economic systems where there is an abundance of capital and a relative scarcity of labour; (ii) the strong and rapid dynamic decline of competitive advantages and quasi-rents, based on the introduction of new information and communication technology; (iii) the strong international competitive pressure from countries with lower wage levels and a greater capability to host the affiliates of multinational companies and to imitate the new information and communication technologies developed in the innovative countries. The results of the empirical analysis, for the OECD countries in the years 1990–92, suggest that a country's competitiveness and therefore its share of total world demand and employment is mostly, if not exclusively, determined by its innovative capacity. Wage levels alone cannot, even when they fall, at least in relative terms, re-establish conditions of full employment: efficiency wages are an important complementary factor in building the innovation capacity of a country.     

The derived demand for knowledge*

ABSTRACT

This paper calls attention on the effects of the economic properties of knowledge on its derived demand, an issue that has not received enough attention in the literature. The results of the analysis suggests that, because of the idiosyncratic – Arrovian – properties of knowledge, a chain of effects takes place: (i) in downstream markets the price of goods that have been produced using knowledge as an intermediate good, falls, (ii) consequently the derived demand in upstream knowledge markets – both within corporations and by them to knowledge-intensive business services – has a lower position, and (iii) the price of knowledge is lower than it should be were knowledge a standard good traded in competitive markets, (iv) with negative consequences in terms of adverse selection of large scale high quality research projects, but (v) possible compensating effects stemming from the use of knowledge spillovers to generate cheaper knowledge. Such results have important implications for economic policy discussions and decisions.     

Percolation Processes, Technological Externalities and the Evolution of Technological Clubs

Technological cooperation has become more widespread in recent years. Percolation processes have been studied in physics as the outcome of four classes of forces termed as density, external pressure, connectivity and receptivity. In this paper the methodology of percolation processes has been adapted to interpret the dynamics of knowledge flows within innovation networks as communication systems and to understand the evolution of technological cooperation among firms both within and among industries.
