This article examines the influence of investor knowledge and the cognitive bias that arises from overconfidence on the advice-seeking behaviour of investors managing their own retirement funds. Specifically, we trace whether overestimating one’s own technical and financial abilities can hinder the willingness to seek advice, particularly when it would be in the investors’ best interest to do so. We identify a subset of investors who are not knowledgeable and yet do not seek advice. These investors exhibit overconfidence in their ability to manage a fund, despite holding under-diversified and less sophisticated portfolios relative to their peers. Given the global rise in investors choosing to manage their own retirement funds and the importance of seeking advice in this context, there are direct policy implications from these results. They suggest a need to identify and target investors who display overconfidence since they are most likely to be managing underperforming retirement investments in the longer term.  相似文献

This paper models logistic and exponential smooth transition adjustments of real exchange rates for six major oil-exporting countries in response to different shocks affecting oil prices. The logistic form captures asymmetric and the exponential form symmetric adjustments in regards to positive and negative oil price shocks. We chose oil-exporting countries that do not peg their exchange rates. For most countries, we detect no statistically significant non-linearities for the adjustment process of real exchange rate returns, be they asymmetric or symmetric, in response to oil supply shocks, idiosyncratic oil-market-specific shocks, and speculative oil-market shocks. Exceptions are oil supply shocks in the UK and possibly Brazil, where exchange rates respond nonlinearly, though the effects are symmetric for both countries. On the other hand, global aggregate demand shocks, which are shocks not originating directly in the oil market, have nonlinear asymmetric effects on real exchange rate returns for Canada, Mexico, Norway and Russia, and nonlinear symmetric effects for Brazil and the UK.  相似文献

This article proposes a generalized notion of extreme multivariate dependence between two random vectors which relies on the extremality of the cross-covariance matrix between these two vectors. Using a partial ordering on the cross-covariance matrices, we also generalize the notion of positive upper dependence. We then propose a means to quantify the strength of the dependence between two given multivariate series and to increase this strength while preserving the marginal distributions. This allows for the design of stress-tests of the dependence between two sets of financial variables that can be useful in portfolio management or derivatives pricing.  相似文献

The problem of industrial replacement has been attacked on an essentially empirical basis by various writers, more especially and quite lately by E. B. Kurtz 1 E. B. Kurtz, Life Expectancy of Physical Property, Ronald Press 1930; R. Winfrey and E. B. Kurtz, Life Characteristics of Physical Property, Bulletin 103 of the Iowa Engineering Experiment Station, Iowa State College, 1931. But its mathematical analysis, which is quite within the range of modern technique, has not in prior publications 2 A special case has been discussed by H. Bateman, Messenger of Mathematics 1920 Vol. 49, p. 134. A more general discussion has been given by R. Frisch, Statsekonomisk Tidskrift, 1927, pp. 117-152. See also B. Meidell, Skandinavisk Aktuarietidskrift 1926 p. 172; J1. Washington Acad. Sci. 1928 p. 437. been advanced to the point at which it becomes applicable to Kurtz's data. The requisite analysis is, as a matter of fact, readily conducted by methods very similar to those applicable to certain problems of population growth and structure, which indeed closely resemble the problem of industrial replacement. 3 F.

This paper is a response to the exposure draft of proposed amendments to IAS 1 Presentation of Financial Statements published by the International Accounting Standards Board (IASB) in March 2006. The objective is to bring to the standard setter's attention research that is relevant to the issues raised in the exposure draft. We review analytic, empirical and experimental research that addresses the presentation of income and the format of the income statement. Overall, there is some support for a single statement of (total) recognised income and expense. However, net income is on average more relevant than comprehensive income, which may favour a two-statement approach. While this result is in line with the IASB's option of the two formats, it does not support the IASB's preference for a single statement.  相似文献

We analyze an endogenous growth model public educational spending. We show that the balanced budget policy and the policy with a slight deficit yield higher growth than a debt policy where public debt grows at the same rate as GDP, unless the government is a creditor. As concerns welfare, it can be demonstrated that a strong deficit policy yields lower welfare than a balanced budget and a slight deficit policy, unless initial debt ratios are low and the intertemporal elasticity of substitution is high. Finally, there may exist an inverted U-shaped relation between welfare and deficit-financed educational spending.  相似文献

ABSTRACT

Drawing from self-regulation and goal-regulation theories, this study focuses on employee proactivity in the context of a hotel that is undergoing change and development. Two hundred twenty eight employees from a hotel undergoing restructuring in Australia took part in this study. A survey instrument was developed and the data obtained from the survey were analyzed. Results show that employee proactive envisioning, employee proactive planning, and employee proactive enacting are positively and significantly interrelated. In addition, results show that organizational climate for innovation and leader vision are positively and significantly related to employee proactive envisioning and serve as situational correlates of employee proactivity. Implications for human resource management, particularly in the hotel industry, are discussed.  相似文献

We analyse the market reaction to divestiture decisions and determine the impact of corporate governance practices. We find the market reaction is significant and can be determined using internal governance mechanisms. We evaluate the determinants of the decision to sell using a control sample of firms displaying characteristics often associated with divestitures indicating that these firms may face the same incentives to divest but elect not to restructure in this manner. Our results suggest that a combination of strong internal and external governance may force managers to act in a manner that is incompatible with their personal desires.  相似文献
