This paper investigates the relationship between subjective expectations regarding the replacement rate of income at retirement and several measures of pension satisfaction. We use panel data on Dutch employees, analyzed with fixed effects models, allowing for correlation between unobserved heterogeneity in satisfaction and optimism or pessimism in expectations. The level of the expected replacement rate is found to be positively related to satisfaction: respondents who revise their expectations of the level of their replacement rate upwards tend to become more satisfied with their pension provisions, in particular with the level of the expected benefits. We do not find robust evidence for a relationship between uncertainty and pension satisfaction.  相似文献

The financial crisis forces public managers to implement cutbacks within their organization. We argue that adopting a change management perspective contributes to our understanding of cutback management by adding a focus on managerial behaviour regarding cutback-related organizational changes. Relying on change management literature, this paper develops a framework for the analysis of cutback management connecting the context, content, process, outcomes and leadership of cutback-related change. From this it follows that managers can be positioned at the intersection of various imperatives, both externally and internally, such as their political leaders and their own subordinates. A research agenda is proposed.  相似文献

Recurrent tasks such as pricing, calibration and risk assessment need to be executed accurately and in real time. We concentrate on parametric option pricing (POP) as a generic instance of parametric conditional expectations and show that polynomial interpolation in the parameter space promises to considerably reduce run-times while maintaining accuracy. The attractive properties of Chebyshev interpolation and its tensorized extension enable us to identify broadly applicable criteria for (sub)exponential convergence and explicit error bounds. The method is most promising when the computation of the prices is most challenging. We therefore investigate its combination with Monte Carlo simulation and analyze the effect of (stochastic) approximations of the interpolation. For a wide and important range of problems, the Chebyshev method turns out to be more efficient than parametric multilevel Monte Carlo. We conclude with a numerical efficiency study.  相似文献

In 1952 merkte V an Y zeren [1] in dit tijdschrift op dat in de meeste elementaire leer-boeken de onafhankelijkheid van en s 2, berekend uit een aselecte steekproef uit de normale verdeling, niet wordt bewezen.
In net bulletin van de VVS 1975, nr. 8 wijdt ook D e K roon [2] hieraan aandacht.
Om de in laatstgenoemd artikel ontwikkelde gedachtengang nog eens onder de aandacht te brengen met name ook van statistische assistenten en analisten en hun docenten, wordt in deze mededeling de hierna te formuleren stelling tot in details elementair bewezen.  相似文献

This article addresses the question of how country‐level governance characteristics moderate the market valuation of research and development (R&D). Using a valuation model and panel data from companies in the European Union, United States, and Japan, we find that effective corporate governance allows the market to better assess a firm's R&D investments. This finding is the conjunction with the effect of the legal system, the financial system, and mechanisms of control. First, as effectiveness of investor protection increases, the market valuation of R&D projects also increases. Second, more developed financial systems do a better job assessing R&D. Third, effective control mechanisms reinforce the positive effect of R&D on a firm's market value. In sum, our findings shed light on how policymakers can increase the benefits from firms' R&D spending and thus foster economic growth and social welfare using these country‐level governance characteristics.  相似文献

Family involvement in business creates idiosyncrasies in firm behavior that promote long‐term, often transgenerational, strategic logics that ostensibly align with the motivations and outcomes of corporate entrepreneurship. Interestingly, extant research provides only minimal insight into the heterogeneous nature of corporate entrepreneurship orientations pursued by family firms. To better understand this heterogeneity, we develop a typology of corporate entrepreneurship in family firms providing a reconciliatory approach to this literary diversity and suggest that the varied corporate entrepreneurship orientations of family firms are impacted by the duality of a family's distinct intention to pursue transgenerational succession and capabilities to acquire external knowledge.  相似文献

Sales control systems are instruments used by firms to improve performance and other organizational outcomes. To understand their antecedents and consequences, this paper conducts a meta‐analysis based on 104 studies. The results showed significant relationships between behaviour‐ and outcome‐based control systems and the complexity of the products, bonuses, financial performance, sales innovation, organizational support and satisfaction with supervisors. The outcomes revealed that behaviour‐based control systems were the most effective mechanism in turbulent markets and for determining financial performance. However, outcome‐based control systems were the most efficient instrument for complex products.  相似文献
