Laundry practices: line-drying and load characteristics

The authors conducted an exploratory study on laundry practices including: contents and number of laundry loads, use of line-drying, laundry items that are line-dried, and availability of equipment for line-drying. The participants dried fewer loads than previously reported in the literature and laundered different items. Subjects used line-drying for selected textiles, viewed line-drying as time consuming and indicated they lacked equipment for line-drying. The respondents did not thoroughly comprehend the meaning of ‘line dry’. From the results, the authors concluded that additional research is needed to identify a standard or typical laundry load. Research is necessary to up-date the body of knowledge, and educators need to inform consumers of the benefits and concerns of line-drying.     

Empirical Evidence on the Implicit Determinants of Compensation in Big 4 Audit Partnerships

This study investigates the implicit financial incentives of individual Big 4 audit partners by examining the association between a partner's compensation and characteristics of the audit firm, audit partner, and individual partner clientele for Big 4 firms in Sweden. Using tax and financial data for individual audit partners and clients, our empirical findings indicate that there is significant variation in the implicit determinants that are associated with compensation across the Big 4. We find that audit partners’ compensation is positively associated with the size of their clientele or the number of publicly traded clients, both of which represent revenue‐generating opportunities. Similarly, compensation and developing an industry specialization are positively related. In three firms, gaining clients is clearly related to an increase in compensation, while losing a client is associated with a reduction in partner income in only one firm. We find that audit partner income is more sensitive to performance‐related incentives, such as attracting new clients, as partners progress in their career. Finally, we find evidence that audit failures, proxied by reporting errors related to issuing a going concern opinion, are associated with lower compensation. These results should be of interest to the auditing profession, audit firms, and regulators when they consider the effects of implicit incentives of partner compensation on audit quality.     

Line-drying versus machine-drying: energy consumption comparison

The purpose of this study was to determine the physical energy utilized in machine-drying and the human energy utilized in line-drying with a standard test laundry load in order to demonstrate the benefits of making a trade-off between mechanized energy and human energy utilized in drying laundry. Comparatively, only a small amount of metabolic energy was utilized in line-drying. Line-drying laundry over an extended period of time, along with similar trade-offs with other household tasks to use more human energy and less mechanized energy, would save energy resources and would contribute to physical health by increasing exercise levels. All data collection occurred at California Polytechnic State University, San Luis Obispo.     

Value and Momentum Everywhere

We find consistent value and momentum return premia across eight diverse markets and asset classes, and a strong common factor structure among their returns. Value and momentum returns correlate more strongly across asset classes than passive exposures to the asset classes, but value and momentum are negatively correlated with each other, both within and across asset classes. Our results indicate the presence of common global risks that we characterize with a three‐factor model. Global funding liquidity risk is a partial source of these patterns, which are identifiable only when examining value and momentum jointly across markets. Our findings present a challenge to existing behavioral, institutional, and rational asset pricing theories that largely focus on U.S. equities.     

Predatory Trading

This paper studies predatory trading, trading that induces and/or exploits the need of other investors to reduce their positions. We show that if one trader needs to sell, others also sell and subsequently buy back the asset. This leads to price overshooting and a reduced liquidation value for the distressed trader. Hence, the market is illiquid when liquidity is most needed. Further, a trader profits from triggering another trader's crisis, and the crisis can spill over across traders and across markets.     

Efficiently Inefficient Markets for Assets and Asset Management

We consider a model where investors can invest directly or search for an asset manager, information about assets is costly, and managers charge an endogenous fee. The efficiency of asset prices is linked to the efficiency of the asset management market: if investors can find managers more easily, more money is allocated to active management, fees are lower, and asset prices are more efficient. Informed managers outperform after fees, uninformed managers underperform, while the average manager's performance depends on the number of “noise allocators.” Small investors should remain uninformed, but large and sophisticated investors benefit from searching for informed active managers since their search cost is low relative to capital. Hence, managers with larger and more sophisticated investors are expected to outperform.     

Dynamic Trading with Predictable Returns and Transaction Costs

We derive a closed‐form optimal dynamic portfolio policy when trading is costly and security returns are predictable by signals with different mean‐reversion speeds. The optimal strategy is characterized by two principles: (1) aim in front of the target, and (2) trade partially toward the current aim. Specifically, the optimal updated portfolio is a linear combination of the existing portfolio and an “aim portfolio,” which is a weighted average of the current Markowitz portfolio (the moving target) and the expected Markowitz portfolios on all future dates (where the target is moving). Intuitively, predictors with slower mean‐reversion (alpha decay) get more weight in the aim portfolio. We implement the optimal strategy for commodity futures and find superior net returns relative to more naive benchmarks.     

Is There a Replication Crisis in Finance?

Several papers argue that financial economics faces a replication crisis because the majority of studies cannot be replicated or are the result of multiple testing of too many factors. We develop and estimate a Bayesian model of factor replication that leads to different conclusions. The majority of asset pricing factors (i) can be replicated; (ii) can be clustered into 13 themes, the majority of which are significant parts of the tangency portfolio; (iii) work out-of-sample in a new large data set covering 93 countries; and (iv) have evidence that is strengthened (not weakened) by the large number of observed factors.     

Principal Portfolios

We propose a new asset pricing framework in which all securities' signals predict each individual return. While the literature focuses on securities' own-signal predictability, assuming equal strength across securities, our framework includes cross-predictability—leading to three main results. First, we derive the optimal strategy in closed form. It consists of eigenvectors of a “prediction matrix,” which we call “principal portfolios.” Second, we decompose the problem into alpha and beta, yielding optimal strategies with, respectively, zero and positive factor exposure. Third, we provide a new test of asset pricing models. Empirically, principal portfolios deliver significant out-of-sample alphas to standard factors in several data sets.
