In this study, we present new evidence that the postwar U.S. federal budget deficit was explosive in nature. Because of the government's inevitable attempts to reduce high or rapidly growing budget deficits, the deficit may contain a substantial component that periodically collapses, which renders the standard unit root tests biased toward stationarity. We apply a newly proposed recursive unit root test for explosiveness, which is known to be powerful to the periodically collapsing component. Although the evidence for explosiveness we found herein is not overwhelming, this study should at the very least serve as a warning against a blind application of standard unit root tests to budget deficits, which may harbor components that periodically collapse. 相似文献

Is it better to move first, or second—to innovate, or to imitate? We show that if one player's information about the profitability of new markets is only modestly superior, the possibility of foreclosing the market can lead to a first‐mover advantage. On the other hand, more extreme information superiority can reverse this, leading to a second‐mover advantage. Knowing more surely what is the best choice, the better‐informed player wants to delay to keep his information private and the less‐informed player wants to delay to learn. Because of this, more accurate information can actually lead to inefficiency by increasing the incentive to delay, and exogenous costs of delay can aid efficiency by neutralizing that strategic incentive. In fact, in some circumstances a player may purposely coarsen his information to deter imitation. 相似文献

ABSTRACTThis paper investigated the current levels of environmental sustainability in restaurants across the U.S. to determine whether a restaurant’s proclivity for environmental sustainability depended on its characteristics such as chain affiliation or restaurant type.A web-based survey was administered to 2,500 top-level restaurant managers, from which a total of 218 responses were judged as usable. The data were analyzed using independentsample t-tests and ANOVA. This study presents an in-depth account of the environmental sustainability in restaurants across the U.S. based on an evaluation of top-level managers. This study also highlights the differences in restaurant environmental sustainability across different restaurant segments. 相似文献

This paper examines whether commodity futures risk factors can predict future economic growth. We test risk factors capturing various spot or term premia and find that only three factors capturing term premia on the basis-momentum, basis, and change in slope are robust predictors for future economic growth, especially for long horizons. Our findings highlight the importance of the term premia, rather than the spot premia on which the literature has mainly focused. Moreover, we find that possible explanations for predictability of commodity factors—the intertemporal asset pricing model and information diffusion explanation—are all inconsistent with our empirical results. 相似文献

The current audit environment encourages auditors to conduct defensive auditing procedures in lieu of using new, innovative, and potentially more effective audit procedures, due to concerns these procedures may be second-guessed in litigation or by audit inspectors such as the PCAOB. As a result, auditors may prefer traditional “generally accepted” procedures over innovative procedures that are potentially more effective. We test recent proposals that an Audit Judgment Rule (AJR) encourages the use of innovative, and potentially more effective, audit procedures analogous to the similar Business Judgment Rule that affords legal protections to corporate directors. Under an AJR, litigators or audit inspectors could not second-guess auditor judgments, even if they perceive that alternate judgments would have ordinarily been reached, provided the auditor's judgment was made in good faith and in a rigorous manner. However, the AJR's requirements that auditors must defend the rigor of their innovative judgments could potentially backfire and lead auditors to select more traditional procedures. Under the framework of goal activation theory, we conduct an experiment with audit managers and seniors and find that an AJR makes auditors less likely to select innovative audit procedures, particularly when audit risk is high. They do so despite believing the innovative procedures to be more effective than the traditional procedures. Findings from a supplementary experiment with experienced auditors further suggest that national office affirmation of the reasonableness of the procedures does not help overcome this effect. Overall, our findings suggest that an AJR may have the unintended consequence of further increasing auditors' focus on more traditional, and potentially less effective, audit procedures. 相似文献

In this paper, we propose two estimators, an integral estimator and a discretized estimator, for the wavelet coefficient of regression functions in nonparametric regression models with heteroscedastic variance. These estimators can be used to test the jumps of the regression function. The model allows for lagged-dependent variables and other mixing regressors. The asymptotic distributions of the statistics are established, and the asymptotic critical values are analytically obtained from the asymptotic distribution. We also use the test to determine consistent estimators for the locations of change points. The jump sizes and locations of change points can be consistently estimated using wavelet coefficients, and the convergency rates of these estimators are derived. We perform some Monte Carlo simulations to check the powers and sizes of the test statistics. Finally, we give practical examples in finance and economics to detect changes in stock returns and short-term interest rates using the empirical wavelet method. 相似文献

This study aims to investigate the effects of the rewards for organ donation as a promotion strategy, which is part of a campaign to promote organ donation in Korea by the non‐profit organization Korean Network for Organ Sharing. This study examines how the effects of rewards for organ donation differ in terms of reward types, public self‐consciousness, and stages of change. An interaction effect between types of reward, stage of change, and the degree of public self‐consciousness was found. Reward type and stage of change were found to function as moderators of the effect of public self‐consciousness on the intention to register for organ donation. The effect of public self‐consciousness on the intention for organ donation was positive and statistically significant among those who were in the contemplation stage and exposed to non‐material types of reward. On the other hand, the effect of public self‐consciousness on the intention for organ donation was negative among those in the pre‐contemplation stage and exposed to material types of reward. Practical implications for organ donation organizations are suggested. Copyright © 2016 John Wiley & Sons, Ltd. 相似文献

Product return behavior and factors that contribute to product returns are an under-researched area, despite significant importance to manufacturers and retailers. The current research attempts to fill the gap by focusing on two factors that shape consumer purchase behavior: (1) whether purchases are planned or unplanned, and (2) whether hedonic or utilitarian motivations drive purchases. The findings show that purchase plans and buying motivations have distinctive and interactive impacts on pre-purchase concerns, self-estimated likelihood of returning purchases, and purchase intentions with or without return policies. When hedonic motivation drives purchases, unplanned (vs. planned) purchases lead to higher return concerns, higher return likelihood, and lower buying intentions. When utilitarian motivation drives purchases, planned and unplanned purchases have comparable return concerns, return likelihood, and buying intentions. This interaction effect on buying intentions dissipates when a lenient return policy is offered. 相似文献

This article reports psychometric evaluation of the Penn State Leadership Competency Inventory (LCI). The 32‐item LCI was validated on a sample of 323 managers in the health care industry. Preliminary validity and reliability evidence of the LCI was established through exploratory factor analysis (EFA), item‐total correlations, Cronbach's alpha coefficients, and confirmatory factor analysis (CFA). The four‐factor leadership competency scale, comprising supervisory and managerial competencies, organizational leadership, personal mastery, and resource leadership, accounted for 58% of variance. According to CFA results, the model fit of the four latent factors of the LCI was confirmed to be appropriate. Cross‐validation with other populations is needed to confirm the factor structure. Limitations and further research recommendations are discussed. 相似文献
