Forecasting the volatility of S&P depositary receipts using GARCH-type models under intraday range-based and return-based proxy measures

We employ four various GARCH-type models, incorporating the skewed generalized t (SGT) errors into those returns innovations exhibiting fat-tails, leptokurtosis and skewness to forecast both volatility and value-at-risk (VaR) for Standard & Poor's Depositary Receipts (SPDRs) from 2002 to 2008. Empirical results indicate that the asymmetric EGARCH model is the most preferable according to purely statistical loss functions. However, the mean mixed error criterion suggests that the EGARCH model facilitates option buyers for improving their trading position performance, while option sellers tend to favor the IGARCH/EGARCH model at shorter/longer trading horizon. For VaR calculations, although these GARCH-type models are likely to over-predict SPDRs' volatility, they are, nevertheless, capable of providing adequate VaR forecasts. Thus, a GARCH genre of model with SGT errors remains a useful technique for measuring and managing potential losses on SPDRs under a turbulent market scenario.     

Institutional environment and firms' sources of financial capital in Central and Eastern Europe

The external business environment is a major determinant of which sources firms select to obtain financial capital. We examine how the regulatory, political, and financial dimensions of the institutional environment influence the extent to which firms rely on informal sources of financial capital. The analyses of data from 2869 firms in twenty-six transition economies in Central and Eastern Europe (CEE) indicate that ineffective regulatory system, underdeveloped financial system, and government corruption are strong determinants of firms' reliance on informal channels for financial capital. We also find that smaller firms are more vulnerable when the local financial system is underdeveloped and the regulatory institutions are less effective in these transition economies. A subgroup analysis of firms' forms of establishment shows that private firms are sensitive to the level of development of the local financial system and state-owned enterprises are particularly sensitive to the degree of corruption.     

A model to study the organizational culture of the family firm

The results of research of the utilitarian type on the culture of the family firm is reported here. A model is built and defined on the basis of the main arguments supporting the following theories: general systems theory, neoinstitutional theory, transformational leadership theory, field theory, learning theory, and group dynamics theory. The resulting model is an instrument that can be used to deepen our understanding of the organizational culture of this type of firm. It should prove to be a powerful tool to exploit the competitive potential of this culture, which has often been noted in the literature.     

The drama of interaction within business networks

We propose a dramaturgical approach to the understanding of business networks with particular reference to IMP research. Our purpose is to focus upon immeasurable processes and practices too often neglected by the tangible, variance modeling of business networks (Colville & Pye, 2010; Rinallo & Golfetto, 2006). This paper follows our call to take language and communication more seriously (Ellis, Lowe & Purchase, 2006). The inventive fluidity of communication, in the form of dramaturgy, when added to the rather more entitative IMP model of Actors, Resources and Activities (Håkansson & Snehota, 1995) creates a more processual, theatrical ‘scenario’ of Actor-Characters, Resource Props and Scripted Activities. We employ the dramaturgical approach of Goffman (1956, 1961) which, in keeping with the approach of the IMP Group is centrally attentive to social interaction. In order to illustrate the potential contribution of this approach, we apply this dramaturgical perspective to the interactions described in a published case study (Helander & Möller, 2007, 2008a, 2008b).     

Effects of Family Socialization in the Organizational Commitment of the Family Firms from the Moral Economy Perspective

South Korean industrial conglomerates (chaebols) are discussed in the context of value-based management (VBM). Recent economics and finance literature on the diversion of corporate resources from the firm to the controlling shareholders (tunneling), for which chaebols are notoriously known, is discussed. Chaebols have engaged in empire building and expropriation of minority shareholders, distorting the process of efficient resource allocation in South Korea, and became the root cause of the 1997 financial crisis. We argue that the 1997 crisis should be viewed as a consequence of chaebols’ systematic deviation from the guiding principles of VBM. We use tunneling within chaebols as an example of the need to directly address prohibition of the expropriation of minority shareholders as a primary postulate of VBM. We argue that VBM should require that the value generated by the firm not be expropriated from minorities, or any stakeholders, by dominant shareholders. We also examine moral and ethical considerations and present explanations as to why the unethical practice of tunneling has been tolerated by the South Korean public. We show that public opinion on tunneling is changing and that the treatment of minority shareholders by chaebols’ controlling families is becoming increasingly unacceptable to South Koreans.     

Estimating the long-run effects of socioeconomic and meteorological factors on the domestic tourism demand for Galicia (Spain)

Tourism is one of the more important sectors for the economy of Galicia (northwest of Spain). The aim of our study is to quantify determinants of Galician domestic tourism demand and their impacts. Additionally, confidence intervals for these impacts are calculated by bootstrapping data. The results show that income, Eastern vacations and the celebration of the Holy Year of the Apostle Saint James have had a relevant positive impact on tourism. There is also a significant positive connection between a meteorological phenomenon, the North Atlantic Oscillation (NAO), and tourism demand. On the other hand, the differential rates of inflation between Galicia and the rest of Spain and the 2008 economic crisis have had a negative effect.     

GPs as firms: Creating an internal market for primary care

Outsiders are often amazed at the lack of contact and communication between general practitioners and other members of the primary care team on the one hand, and the rest of the national health service on the other. One way to help close the gap and improve services generally would be to provide GPS with appropriate incentives.     

Flexibility at the Margin and Labor Market Volatility in OECD Countries*

We study the business‐cycle behavior of segmented labor markets with flexibility at the margin (e.g., just affecting fixed‐term contracts). We present a matching model with temporary and permanent jobs (i) where there is a gap in the firing costs associated with these types of jobs and (ii) where there are restrictions in the creation and duration of fixed‐term contracts. We show that a labor market with ``flexibility at the margin'' increases the unemployment volatility with respect to one that is fully regulated. This analysis yields new insights into the interpretation of the recent volatility changes witnessed in the OECD area.
