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

We use lab experiments to study policies that address common pool resource overuse. We look at a price mechanism, specifically a Pigouvian subsidy, and four non-price interventions. The non-price policies are information alone, information with a normative message, communication alone, and normative messages with communication allowed. In all experiment sessions, no intervention occurs in the first seven and last seven rounds, allowing us to examine the effects of introducing and taking away a policy. The subsidy leads to near-efficient extraction, but surprisingly leads groups that were not over-extracting to also reduce extraction. This over-compliance decreases efficiency, although on net the subsidy is the most efficiency-enhancing intervention. Information provision, communication, normative appeals, and normative appeals combined with communication all reduce over-extraction (though by less than the subsidy) without exacerbating over-compliance; however, the effects of information alone and communication alone are small and not robust. The non-price policies cause a decline in over-extraction of from 0.549 (information) to 11.441 % (normative appeals with communication). These effects are of the same order of magnitude as the effects seen in major field studies of conservation messaging. The subsidy has the worst persistence properties (after the intervention ceases), while normative messages with communication have the best.  相似文献

This paper discusses the consequences of securitization and how it links to the Austrian Business Cycle Theory (ABCT). The argument that securitization is behind fiduciary credit expansion preceding the 2008 crisis is incomplete. Consolidated balance sheet analysis demonstrates that securitization per se actually sterilizes the inflationary effect of previous fiduciary credits by transforming them into credits backed by voluntary savings. This sterilization stage is subsequently followed by new fiduciary credits issuance as securitization creates excess reserves and excess capital for banks. However, when securitization is used as a tool to implement arbitrage strategies of the Basel prudential rules, it enables banks to create more fiduciary credit while time preference remains unchanged. This creates the conditions for business cycle amplification.  相似文献

I am interested in how models, practices, and concepts travel across specialties and thereby change and are changed in turn. In the present essay I discuss Gordon Tullock’s ideas about the relationship between biology and economics in the light of his correspondence with the biologist Garrett Hardin. Tullock contributed to one of Hardin’s edited projects, but they took different approaches to related problems, which I characterize as problems of coordinated action. Tullock saw that he and Hardin were up to a similar line of inquiry, and Hardin engaged with him up to a point, but ultimately the biologist differed with the economist regarding the potential for the reliability of a regulating power such as the state.  相似文献

The authors extend prior literature by examining, in two distinct field settings, smallest meaningful pay increases (SMPIs) in terms of magnitude, behavioral intention, and affective reactions. In Study 1, a two‐wave study of 177 employees of a university medical center in the United States, the authors find stable thresholds of about 5.0 percent for positive reactions to pay increases (magnitude [5.4 percent], behavioral intentions [4.2 percent], and affective reactions [5.6 percent]). In Study 2, a sample of 495 university employees in Finland, the authors also find stable but slightly higher thresholds of about 8 percent for behavioral intentions (8.4 percent) and positive affective reactions (7.2 percent) to pay increases. They also find threshold effects of ?5.7 percent for behavioral intentions and ?5.8 percent for negative affective reactions in response to restricted future pay increases levied in the transition to a new pay system. Discussion of the results centers on pay raise administration and future research regarding implied and direct pay reductions. © 2015 Wiley Periodicals, Inc.  相似文献

Perhaps the most common criticism of socially responsible investment funds is that imposing non‐financial screens restricts investment opportunities, reduces diversification efficiencies and thereby adversely impacts performance. In this study we investigate this proposition and test whether the number of screens employed has a linear or curvilinear relation with return. Moreover, we analyse the link between screening intensity and risk. Screening intensity has no effect on unadjusted (raw) returns or idiosyncratic risk. However, we find a significant reduction in α of 70 basis points per screen using the Carhart performance model. Increased screening results in lower systematic risk – in line with managers choosing lower β stocks to minimize overall risk.  相似文献

Forecasting performance of December corn and November soybean futures contracts during the previous spring was evaluated using the commonly specified price-level and percent-change models. These models invoke different assumptions regarding stationarity. Using Stein's analytical framework, results for the price-level model suggest avoidable social loss existed in the soybean market since 1973, because November futures provided biased forecasts. Regression R2s for both corn and soybeans declined substantially between 1952–1972 and 1973–1997, suggesting total social loss increased. By contrast, results from the percent-change model suggest only unavoidable social loss existed in the corn and soybean markets, because the futures provided unbiased forecasts. R2 increased for corn but declined for soybeans, suggesting unavoidable social loss declined for corn, but increased for soybeans. The important, conflicting nature of the results from the two models underscores the importance of examining alternative model specifications when evaluating price forecasting performance. © 1999 John Wiley & Sons, Inc.
