A meta-analysis on employee perceptions of human resource strength: Examining the mediating versus moderating hypotheses

Human resource (HR) strength research has substantially informed an understanding of the relationship between HR practices and employee-level outcomes. However, a key unresolved issue is whether employee perceptions of HR strength act as a mediator or a moderator in the relationship between HR practices and these outcomes. A meta-analysis of 42 studies (comprising 65 samples and 29,444 unique participants) was conducted to address this issue. Results support the mediating hypothesis for all five employee outcomes: employee reactions, proactive behavior, burnout, performance, and perceived organizational effectiveness. Conversely, the moderating hypothesis was only supported for employee performance. In addition, we examined five study characteristics (the operationalization of perceived HR strength, research study design, industry, sampling strategy, and publication status) as moderators. Using this analysis, we test the robustness of our main results and identify sources of heterogeneity in the results across studies. The results show that the mediating hypothesis still holds under different study designs and contexts. Theoretical and practical implications of these results are discussed.     

Bubbles,Froth and Facts: Another Look at the Masters Hypothesis in Commodity Futures Markets

The Masters Hypothesis suggests that long‐only index funds were the main cause of a massive increase in commodity prices in 2007–2008 and 2011–2012. Central to the Masters Hypothesis are three basic tenets: (i) long‐only commodity index funds were directly responsible for driving futures prices higher; (ii) the deviations from fundamental value were economically very large; (iii) the impact was pervasive across commodity futures markets. There has been a great deal of empirical research on the Masters Hypothesis and commodity market bubbles. However, surprisingly few studies have found evidence that directly support the main tenets of the Masters Hypothesis. Some have attributed the lack of supporting evidence to the low‐power of time‐series tests, market efficiency issues and a lack of conditioning variables within models. In this paper, we address each of these issues using updated data and new empirical approaches. Still, price behaviour consistent with the Masters Hypothesis is surprisingly difficult to find in the data. This is an important finding given the on‐going policy debate and regulations proposed or being implemented to limit speculative positions in these markets.     

The Variation of Economic Risk Premiums in Real Estate Returns

We examine the predictable components of returns on stocks, bonds, and real estate investment trusts (REITs). We employ a multiple-beta asset pricing model and find that there are varying degrees of predictability among stocks, bonds, and REITs. Furthermore, we find that most of the predictability of returns is associated with the economic variables employed in the asset pricing model. The stock market risk premium is highly important in capturing the predictable variation in stock portfolios, and the bond market risk premiums (term and risk structure of interest rates) are important in capturing the predictable variation in bond portfolios. For REITs, however, both the stock and bond market risk premiums capture the predictable variation in returns. REITs have comparable return predictability to stock portfolios. We conclude that there is an important economic risk premium for REITs that are not captured by traditional multiple-beta asset pricing models.     

Multidisciplinary and Multimethod Research for Addressing Contemporary Supply Chain Challenges

To achieve differential performance in today’s marketplace, supply chain decision makers must manage complex, multifaceted, and nuanced issues. To help decision makers, and advance the supply chain discipline, researchers need to consider how multidisciplinary and/or multimethod research can provide greater insight into today’s and tomorrow’s challenges and opportunities. We explore questions related to the supply chain–finance interface and global supply chain management to exemplify how multidisciplinary and multimethod research can increase the insight and influence of our research contributions.     

Price discovery in a private cash forward market for lumber

Cash forward contracting is a common, and often preferred, means of managing commodity price risk in many industries. Despite this, little is known about the performance of cash forward markets, in particular the role they play in price discovery. The US lumber market provides a unique case for examining this issue. The Bloch Lumber Company maintains an active cash forward market for many lumber products, and publishes benchmark forward prices on their website and disseminates these prices to data vendors. Focusing on 2×4 random lengths lumber and 7/16 oriented strand board, this research examines the lead–lag relationships between the 3-month forward prices published by Bloch Lumber, representative spot prices, and lumber futures prices at the Chicago Mercantile Exchange. Results suggest that at least for 2×4 random lengths lumber, the forward prices published by Block Lumber lead both the spot price and futures price, suggesting that this private cash forward market provides some level of price discovery in the lumber markets.     

Sustainable Supply Chains in the Age of AI and Digitization: Research Challenges and Opportunities

Sustainability has become a global corporate mandate with implementation impacted by two key trends. The first is recognition that global supply chains have a profound impact on sustainability which requires “greening” the entire supply chain. The second is technology—digitization, artificial intelligence (AI), and “big data”—which have become ubiquitous. These technologies are impacting every aspect of how companies organize and manage their supply chains and have a powerful impact on sustainability. In this essay, we synthesize current dominant themes in research on sustainable supply chains in the age of digitization. We also highlight potential new research opportunities and challenges and showcase the papers in our STF.     

A Model of the Relative Income Hypothesis

James Duesenberry's (1949) relative income hypothesis holds substantial empirical credibility, as well as a rich set of implications. Although present in the pages of leading economics journals, the hypothesis has become all but foreign to the blackboards of economics classrooms. To help reintegrate the concept into the undergraduate economics curriculum, the author constructs a model of the relative income hypothesis to present a few of its important properties and implications. Negative spending externalities, the effect of public provision taxes on wasteful spending races, and the Pareto implications of universal income growth are illustrated within a two-good consumption space as a method of introducing this rich literature to a greater number of introductory and intermediate economics students.     

Rational Abstention and the Congressional Vote Choice

Research on voting, particularly on legislative behavior, tends to focus on the choices of those casting ballots. Yet, intuitively, abstentions and vote choice should be jointly determined. As such, the relevance of participation depends upon both the extent to which it can be explained by the costs and the benefits of voting and on the nature of the interactions between participation and preferences. To this end, we provide a framework for explaining roll call behavior that simultaneously considers legislators' decisions about whether and how to vote. Application to roll call voting in the 104th Congress finds that abstention and voting choices are integrated; our approach generates sensible and substantively important results which yield important insights into legislative behavior and public policy.
