In our discussion in the last issue of Journal of FinancialEconometrics (JFEC) of the nonparametric methods developed byBarndorff-Nielsen and Shephard (2006) to detect jumps in thelocal behavior of the continuous time path of a price process,we observed these tests were not designed to detect major pricediscontinuity events such as the 1987 crash, since the testingmethodology precludes jumps in adjacent time intervals. Indeed,a major event such as Black Monday is characterized by a sequenceof jumps in consecutive time intervals throughout the day. Inthe interest of thematic continuity, lets pursue thematter of jumps further. The first article in the current issue by Hossein Asgharianand Chistoffer Bengtsson addresses directly the detection ofbig events in stock prices. More particularly, the authors analyzethe spillover of jumps across international stock markets. Tomeasure jumps, the authors formulate a parametric model in . . . [Full Text of this Article] 相似文献

In this article, we examine the role of institutional context, organizational structures and trade union strategies in tempering membership decline in the number of trade unions in Poland. Empirical data include membership statistics collected for NSZZ Solidarno?? and 54 affiliates of two other largest trade union confederations (OPZZ and FZZ) supplemented by semi‐structured interviews with union leaders. In a decentralized collective bargaining system in Poland, a centralized trade union confederation (NSZZ Solidarno??) can more easily shift resources to efficiently organize workers than decentralized confederations, OPZZ and FZZ, whose development is mostly driven by competing trade unions representing narrower occupational groups. In conclusion, this observation is put in a broader context of the debates about trade union renewal in Eastern Europe. 相似文献

Abstract
Aim
Cutaneous T-cell Lymphoma (CTCL) is a rare form of non-Hodgkin lymphoma characterized by skin lesions, which can negatively impact the quality of life of both patients and their caregivers. The Decision Support Unit (DSU) at the National Institute for Health and Care Excellence (NICE) in the UK recently outlined a rationale for the inclusion of caregiver burden in economic evaluations. This study aimed to estimate utilities for health states associated with being a caregiver for an individual with CTCL at different stages of treatment. 相似文献105.

Highly risk-averse retirees are generally advised to adopt a fixed spending strategy such as the 4% withdrawal rule. To prevent the premature depletion of a retirement portfolio, the rule attempts to proxy as the ‘safe withdrawal rate’. But a constant withdrawal rate means that retirees accumulate unspent surpluses when markets outperform and face spending shortfalls when markets underperform. While a safe withdrawal rate can prevent spending shortfalls, the opportunity cost of unspent surpluses associated with this strategy can be extreme. We apply a range of basic investment decision rules to a retirement portfolio applying various withdrawal rates and examine the probability of shortfalls over a retirement horizon. Using a block bootstrap simulation technique, we examine decision rules relating to stock and bond investments. Our results show that retirement portfolios with a bias towards stocks coupled with a decision rule that sources withdrawals from bonds and cash before stocks significantly outperforms alternative withdrawal strategies, despite the inherent increase in volatility. This finding is in direct contrast to the safe withdrawal rate conventions used in contemporary financial advice models. 相似文献

Value creation with Dye’s disclosure option: optimal risk-shielding with an upper tailed disclosure strategy 总被引:1,自引:1,他引:0

Dye [J Account Res 23 (1985) 123] showed that the optimal disclosure policy, when a manager is randomly endowed with perfect private information,
is upper tailed, i.e., the manager only discloses firm value above an appropriate cutoff level. We interpret this strategically
as an optimal exercise by management of the embedded formal option to report value. Given any disclosure cutoff level, we value the corresponding option using contingent claims analysis. It
is shown that the Dye disclosure cutoff value maximizes the formal option value. We find it to be the minimum possible conditional valuation (conditioned by non-disclosure) which is thus consistent with the intuition that investors should value
conservatively. We show how the Dye cutoff can be interpreted as a strike price in a ‘protective put’ which offers a shield
against risk of disclosure of low value. The strategic analysis is further extended by allowing the probability level that
the manager is informed to be a choice variable. We show that the manager will never choose to be perfectly endowed with information,
and is likely to be more endowed than unendowed. We also present a simple worked example which shows how the total value of
the firm changes once the Dye option is formally incorporated.

Using sorting procedures and cross-sectional tests, we investigate the long-run post-IPO performance and its sources in the Central and Eastern European (CEE) markets. We examine over 1100 stocks from 11 CEE countries for the period 2002–2014. We find that “old stocks” perform significantly better than “young stocks”, but only when the market beta is the sole risk factor considered. After accounting for the size and value effects, the IPO firms perform neither better nor worse than non-issuing companies. The sources of the initial low B/M ratios of debuting companies may lie in time-varying financial quality. The market newcomers are financially healthier than their older counterparts. However, over 2–5 years the fundamentals deteriorate and the financial standing regresses to the mean. 相似文献

In this article we present the heuristic-systematic model (Chaiken, 1980, 1987; Chaiken, Liberman, & Eagly, 1989) as a theoretical framework for research on product warning labels. The model proposes two fundamental information processing modes. When processing systematically, perceivers access, scrutinize, and integrate all useful information to reach their judgment. In contrast, heuristic processing involves the use of learned knowledge structures in the form of simple decision rules, or cognitive heuristics, to reach judgments. In addition to proposing when either or both of these processing modes will occur, and with what effect, the model also specifies three different underlying types of processing motivations, termed accuracy, defense, and impression, each with implications for information processing and judgments. This model is used to explain past findings on the effectiveness of product warning labels, and to suggest new areas for future research as well as practical guidelines for the design of warning labels. © 1998 John Wiley & Sons, Inc. 相似文献

There is growing interest in Nova Scotia's Environmental Farm Plan (NS EFP) program among farmers and policy makers because of several reasons. First, effectiveness of standardized or uniform beneficial management practices in mitigating the negative environmental impacts from agriculture is limited by inherent heterogeneities in agricultural production systems. In addition, there is heightened interest in farmers generating ecological goods and services to society. This study investigates the determinants of participation in the NS EFP program. A discrete choice model of NS EFP participation was applied to a sample of 83 farmers (representing a 31% response rate). To increase relevance of the study to program administrators, the study also examined farmers’ use of various channels and sources of information on farm conservation practices. The most used sources of information on farm conservation practices include a mix of interpersonal sources and government agencies. Although online information (especially those available for free) appears to be gaining popularity in usage, overall, electronic and computer channels of information (especially radio and television) were used less compared with traditional channels of communicating farm conservation information (such as newsletters and agricultural magazines). Regression analysis suggests that farm characteristics (i.e., farm type, farm size, farm income) and farmer capacity variables (i.e., specialized training and knowledge from EFP program information sessions and workshops, and on-farm stewardship demonstrations) were significant determinants of environmental farm planning. 相似文献

This paper analyzes why gold mining firms use options instead of linear strategies to hedge their gold price risk. Consistent with financial constraints based theories, the largest and least financially constrained firms are the most likely to hedge with insurance strategies (put options), while more constrained firms finance the purchase of puts by selling calls (collars). The most financially constrained firms use strategies that involve selling calls. Firms with large investment programs are also more likely to use insurance rather than linear strategies. Firms’ hedging instrument choices are also correlated with current market conditions, suggesting that managers’ market views partially drive hedging instrument choices. 相似文献
