Sequential estimation of shape parameters in multivariate dynamic models

Sequential maximum likelihood and GMM estimators of distributional parameters obtained from the standardised innovations of multivariate conditionally heteroskedastic dynamic regression models evaluated at Gaussian PML estimators preserve the consistency of mean and variance parameters while allowing for realistic distributions. We assess their efficiency, and obtain moment conditions leading to sequential estimators as efficient as their joint ML counterparts. We also obtain standard errors for VaR and CoVaR, and analyse the effects on these measures of distributional misspecification. Finally, we illustrate the small sample performance of these procedures through simulations and apply them to analyse the risk of large eurozone banks.     

How organizational support impacts affective commitment and turnover among Italian nurses: a multilevel mediation model

This study examines multilevel relationships between perceived organizational support (POS), affective commitment and voluntary turnover among nurses. We explored the mediation role of affective commitment between POS and turnover behavior at both individual and work-unit levels. This cross-level study involved 945 Italian nurses from 60 work units. We hypothesized and showed that collective affective commitment fully mediated the impact of climate for POS on individual and collective turnover among nurses. This study helps explain the variance in turnover among nurses in healthcare organizations by analyzing the influence of unit-level climate on individual behavior. Results stress that social environments within wards are important in explaining the processes by which nurses decide to quit their work unit.     

Input–output interactions and optimal monetary policy

This paper deals with the implications of factor demand linkages for monetary policy design in a two-sector dynamic general equilibrium model. Part of the output of each sector serves as a production input in both sectors, in accordance with a realistic input–output structure. Strategic complementarities induced by factor demand linkages significantly alter the transmission of shocks and amplify the loss of social welfare under optimal monetary policy, compared to what is observed in standard two-sector models. The distinction between value added and gross output that naturally arises in this context is of key importance to explore the welfare properties of the model economy. A flexible inflation targeting regime is close to optimal only if the central bank balances inflation and value added variability. Otherwise, targeting gross output variability entails a substantial increase in the loss of welfare.

The new EU merger regulation: Implications for EU‐U.S. merger strategies

This article examines the implications of the new EU merger regulation (EU 139/2004) on international merger strategies. Important changes in the new regulation on both a substantive and procedural level are analyzed in the comparative context of EU and U.S. merger‐control policies. In particular, the article evaluates whether the “substantial impediment to effective competition” (SIEC) test in the new regulation implies convergence with the U.S. “substantial lessening of competition” (SLC) benchmark. In this context, the article develops scenarios for convergence between EU and U.S. merger‐control policies. The EU merger process has emerged against a background of significant political and institutional development in the European Union, and this is an important explanatory element in the development of competition policy in general and for the new merger regulation in particular. It also has implications for merger strategies examined at the end of the article. © 2006 Wiley Periodicals, Inc.     

Functions of industrial supplier relationships and their impact on relationship quality

Although recent scholarly work on business relationships often discusses relationship quality as a major issue, especially with regard to the phenomenon of vendor stratification, there is still little empirical research on this important construct. In this paper, the authors provide a thorough conceptualization of relationship quality and its possible antecedents, i.e., the direct and indirect functions of the relationship for the customer. Drawing on an empirical base of 230 buyer questionnaires, the authors show that the extent to which a supplier fulfills direct and indirect functions in a relationship has a direct positive impact on the relationship quality perceived by the customer. This impact is especially strong when the customer can easily replace the supplier or, in other words, when the supplier faces competition. The findings are discussed and the authors provide managerial implications for decision-makers from both buyer and supplier organizations.
