A Multivariate Time‐Series Examination of Motor Carrier Safety Behaviors

Motor carriers’ operational safety affects multiple stakeholders including truck drivers, motor carriers, insurance companies, shippers, and the general public. In this article, I devise and test theory regarding motor carriers’ longitudinal performance for three classes of safety behaviors linked to carriers’ accident rates—Unsafe Driving, Hours‐of‐Service Compliance, and Vehicle Maintenance—tracked by the Federal Motor Carrier Safety Administration as part of the Compliance, Safety, and Accountability (CSA) program. Specifically, I draw on core concepts from sociological agency theory and resource dependency theory to devise middle‐range theory that generates never‐before‐tested hypotheses regarding carriers’ longitudinal safety performance for these classes of safety behaviors after the start of the CSA program. The hypothesized predictions are tested by fitting a series of multivariate latent curve models to four years of panel data for a random sample of 484 large, for‐hire motor carriers operating in the United States. The empirical findings corroborate the theoretical predictions and remain after robustness testing. These findings have important implications for scholars, motor carrier managers, procurers of motor carrier transportation services, and public policy makers.     

Reconciling Alternative Theories for the Safety of Owner–Operators

Motor carrier safety is an important concern of shippers, carriers, policy makers, consignees, insurance providers, and the motoring public. One aspect of carrier safety that has garnered substantial attention is whether carriers making greater use of owner–operators are more or less safe vis‐à‐vis carriers making greater use of employee drivers. Currently, conflicting theoretical predictions exist regarding the direction of this relationship. In this article, we offer a reconciliation of the alternative theoretical predictions by developing a coherent theory that merges sociological rational choice theory and theory regarding motor carrier safety. We subject our theory to empirical testing by fitting a series of seemingly unrelated regression models to a vector of safety measures tracked as part of the Federal Motor Carrier Safety Administration's Compliance, Safety, and Accountability program. Our results are consistent with our proposed theory of owner—operator safety and provide meaningful theoretical and managerial implications and directions for future research.     

Developing and Testing a Dynamic Theory of Motor Carrier Safety

Developing an understanding of the longitudinal relationships between different measures of motor carrier safety is important to advance theory and practice regarding this significant supply chain management and public policy issue. In this article, we combine core principles from several theoretical traditions to propose a dynamic theory of motor carrier safety that specifies the longitudinal relationships between three core measures of safety publically reported by the Federal Motor Carrier Safety Administration: unsafe driving, hour‐of‐service compliance, and vehicle maintenance. We test this theory using four years of longitudinal data on motor carrier safety for a random sample of large, for‐hire motor carriers. Results from fitting a vector multivariate autoregressive moving average time‐series model are largely consistent with the theory we propose. We describe the implications of our research for supply chain management theory and practice, summarize limitations, and suggest directions for future research.     

A New Perspective on Returns to Scale for Truckload Motor Carriers

Understanding how motor carriers' size affects their productivity (e.g., miles per power unit) is of fundamental importance to carrier managers, shippers, and investors, because the nature of this relationship should influence carriers' strategies with regard to growth. In the truckload (TL) sector, the prevailing assumption is that TL carriers face constant returns to scale such that productivity differs little between large and small carriers. While empirical findings from several studies conducted since deregulation are consistent with this assumption, we contend that the true relationship between carrier size and productivity is more nuanced and is contingent on carriers' level of technical efficiency. Specifically, we develop and test middle range theory that predicts increasing returns to scale for carriers with low technical efficiency, constant returns to scale for carriers with average technical efficiency, and decreasing returns to scale for carriers with high technical efficiency. We test our theory by estimating production functions using quantile regression for data collected from the U.S. Department of Transportation for 1,068 TL carriers. Results from our analyses corroborate our predictions. Our findings hold valuable implications for the logistics literature as well as TL carrier management, shippers, and other industry stakeholders.     

Effects of Motor Carriers’ Growth or Contraction on Safety: A Multiyear Panel Analysis

Motor carrier safety remains a highly relevant issue for supply chain managers and scholars because carriers’ safety affects supply chains as well as the welfare of the motoring public. This article enriches understanding regarding this topic by investigating how motor carriers’ growth or contraction since the start of the Compliance, Safety, and Accountability (CSA) program in 2010 affects their safety performance. Drawing on core principles from theories regarding internal adjustment costs from economics and nonscale free capabilities from management, we explain why carriers’ growth or contraction should differentially affect various safety metrics tracked by the CSA program. To test our theory, we assemble a multiyear panel data set for over 1,000 of the largest for‐hire motor carriers operating in the United States by melding together several different governmental data sources. We fit a series of multivariate seemingly unrelated regression models to test our hypothesized effects. Our results corroborate our theorized predictions and are robust to alternative model specifications. We conclude by detailing how this work contributes to extant theory, summarizing managerial and policy implications, highlighting limitations, and suggesting directions for further pursuit.     

Strategic Purity and Efficiency in the Motor Carrier Industry: A Multiyear Panel Investigation

Two questions facing motor carrier managers are (1) whether carriers should specialize in providing full truckload (TL) or less‐than‐truckload (LTL) services vis‐à‐vis offering mix of both and (2) whether this decision is contingent on carrier size. Yet, the literature provides little guidance because research to date has offered contradictory theoretical predictions and inconsistent empirical findings. Drawing on the theory of strategic purity and information processing theory, we explain why service specialization is likely to increase carriers' technical efficiency and why size will have a more pronounced effect on technical efficiency for carriers specializing in LTL services versus TL services. To test our theory, we assemble a panel data set from archival government sources regarding general freight motor carriers' provision of LTL and TL services. We measure carriers' technical efficiency using data envelopment analysis and test our hypotheses by fitting a series of panel data mixed‐effects models. Our results indicate that carriers are most technically efficient when they specialize in one service type. We also find that size positively affects technical efficiency but only for carriers specializing in LTL services; no returns to scale with regard to technical efficiency exist for carriers specializing in TL services.     

CUTTING LOGISTICS COSTS WITH OCEAN CARRIER SELECTION

Two decades of survey research has shown that transit‐time differences among ocean carriers are often secondary considerations in carrier selection. However, this study found that shippers can pay substantial premiums for superior ocean transit‐time service, and cut logistics costs even when substantial variability occurs in landside segments of supply chains.     

How Does Driver Turnover Affect Motor Carrier Safety Performance and What Can Managers Do About It?

The trucking industry is the lifeblood of supply chains. Truck driver turnover and motor carrier safety are two salient issues affecting this industry. While turnover by itself presents a challenge due to the cost of replacing drivers, it takes on additional urgency because turnover may affect motor carrier safety. However, driver turnover research has focused predominantly on identifying factors affecting turnover, thus resulting in limited understanding of how turnover affects motor carrier performance, particularly with regard to safety. This reduces our ability to provide guidance to managers who have to address driver turnover. In this article, we extend prior research by drawing from several theoretical lenses to develop and test theory of the turnover–safety relationship. Furthermore, we investigate whether carrier managers can mitigate the effect of turnover on safety by embedding knowledge in carriers’ routines using activity control, a formal management control mechanism. We employ a longitudinal data set composed of primary and secondary data sources to test our hypotheses. We find the turnover–safety relationship is best characterized by a monotonic negative attenuated pattern and that high levels of activity control mitigate the negative effect of driver turnover on motor carrier safety in domains more under drivers’ control.     

What’s in a Score? Differences in Consumers’ Credit Knowledge Using OLS and Quantile Regressions

Credit literacy depends, in part, on understanding credit reports and scores. The U.S. Government Accountability Office conducted a study in 2004 to assess consumers’ knowledge of credit reports, credit scores, and the dispute resolution process. This study uses the Government Accountability Office data and estimates a series of ordinary least squares and quantile regressions to identify specific subgroups of the population that could benefit from more targeted consumer policies and financial education. The findings from this research have important implications for consumer educators, financial professionals, and policy makers, especially with respect to national strategies designed to improve consumers’ financial well‐being.     

The Influence of Workplace Justice Perceptions on Commercial Driver Turnover Intentions

Employee retention is a critical and challenging workplace issue including in the U.S. motor carrier industry with its perennially high driver turnover rates. Truck driver retention affects supply chain performance because of its impact on carrier operating safety and the service capacity of the trucking industry. Government authorities exert an influence on truck driver retention via the safety policies, labor policies, and regulations they mandate. A proposed rule requiring electronic on‐board recorders of some carrier drivers offers an opportunity to investigate the influence of government policy on driver work intentions. In this study we examine this influence through the lens of procedural justice theory. Drawing on procedural justice literature, we develop a model which examines the procedural justice perceptions of commercial drivers and the subsequent impact on their decision‐making behavior, including their organizational and industry intentions to remain or quit.     

Sovereign credit ratings,capital flows and financial sector development in emerging markets

How does the sovereign credit ratings history provided by independent ratings agencies affect domestic financial sector development and international capital inflows to emerging countries? We address this question utilizing a comprehensive dataset of sovereign credit ratings from Standard and Poor's from 1995–2003 for a cross-section of 51 emerging markets. Within a panel data estimation framework, we examine financial sector development and the influence of sovereign credit ratings provision, controlling for various economic and corporate governance factors identified in the financial development literature. We find strong evidence that our sovereign credit rating measures do affect financial intermediary sector developments and capital flows. We find that i) long-term foreign currency sovereign credit ratings are important for encouraging financial intermediary development and for attracting capital flows. ii) Long-term local currency ratings stimulate domestic market growth but discourage international capital flows. iii) Short-term ratings (both foreign and local currency denominated) retard all forms of financial developments and capital flows. There are important implications in this research for policy makers to encourage the provision of longer-term credit ratings to promote financial development in emerging economies.     

Electronic Logging Device Compliance of Small and Medium Size Motor Carriers Prior to the December 18, 2017, Mandate

With few exceptions, motor carriers operating in the United States were required to install electronic logging devices (ELDs) as of December 18, 2017. Noncompliance exposed carriers to risk of fines from enforcement agencies. This research examines compliance behaviors of small and medium size carriers in the four months leading up to the ELD mandate, focusing on the effects of carriers’ size and geographic range of operation (e.g., regional vs. national). Drawing on sociological agency theory, new institutional theory, and theory regarding regulatory compliance, we explain why (1) carriers’ size displays a nonlinear relationship with ELD compliance, (2) the positive effect of carrier size on ELD compliance diminishes as the enforcement deadline approached, (3) carriers with operations covering wider geographic areas have higher rates of compliance, and (4) the effect of wider geographic range of operations on compliance will become more pronounced as the enforcement deadline approached. We test our theory using ELD compliance data collected by an industry data vendor, CarrierLists, from September 2017 through December 2017 from 3,910 motor carriers. Results from a series of discrete choice logistic regression models corroborate our predictions. These results have important implications for carriers, shippers, and regulators.     

Sweating the Assets: Asset Leanness and Financial Performance in the Motor Carrier Industry

Originally adopted by the automotive manufacturers, lean management practices have since been applied to many other manufacturing industries. This study reviews the different theoretical perspectives on the leanness‐performance relationship in the context of the motor carriage industry. Drawing on both the lean management in logistics and organizational slack literatures, we develop hypotheses addressing the link between asset leanness and financial performance. These hypotheses are empirically tested using a comprehensive panel data set of 1,172 firm‐quarter observations from the U.S. publicly traded truckload motor carriers. Initially expecting an inverted U‐shaped relationship between asset leanness and performance, findings indicated a U‐shaped relationship, both for carriers' total assets and the subset of trailer assets.     

Corporate Social and Financial Performance Re-Examined: Industry Effects in a Linear Mixed Model Analysis

In this research, we shed new light on the empirical link between corporate social performance (CSP) and corporate financial performance (CFP) via the application of empirical models and methods new to the CSP?CCFP literature. Applying advanced financial models to a uniquely constructed panel dataset, we demonstrate that a significant overall CSP?CCFP relationship exists and that this relationship is, in part, conditioned on firms?? industry-specific context. To accommodate the estimation of time-invariant industry and industry-interaction effects, we estimate linear mixed models in our test of the CSP?CCFP relationship. Our results show both a significant overall CSP effect as well as significant industry effects between CSP and CFP. In conflict with expectations, the unweighted average effect of CSP on CFP is negative. Our industry analysis, however, shows that in over 17% of the industries in our sample, the effect of CSP on CFP for socially responsible firms is positive. We also examine the multidimensional nature of the CSP construct in an industry context by exploring the CSP dimension?Cindustry nexus and identify dimensions of social performance that are associated with either better or worse financial performance. Our results confirm the existence of disparate CSP dimension?Cindustry effects on CFP, thus our results provide important and actionable information to decision makers considering whether and how to commit corporate resources to social performance.     

Adoption of multiple electronic marketplaces: Antecedents from a grounded theory study

To achieve economies of scope, most motor carriers combine long-term contracts with shippers and brokers with periodic spot assignments found on electronic marketplaces (EMs). While previous research has addressed how carriers adopt an EM, we know little about factors that influence carriers to adopt multiple EMs. Given the rise of the platform economy of the trucking industry, we chose to address this gap and generate mid-range theory on adopting multiple EMs in a logistics context. To do this, we applied grounded theory and conducted 23 interviews with motor carriers and EM experts in North America and Europe until we reached theoretical saturation. Our findings reveal that many motor carriers adopt a portfolio of different EMs, and that their awareness of platforms, expected and realized benefits, attitude, and vigilance determine how they configure their EM portfolios. The implication for existing theory is that, while previous studies depicted EM adoption from a single-system perspective, we found that it is actually a continuous selection process that follows a portfolio perspective. Our paper also has implications for practice in that it illuminates the rationales behind EM portfolio development and identifies actionable factors that can help managers configure stronger portfolios.     

Financial Globalisation and Emerging Markets Volatility

The volatility of capital flows to emerging market (EM) countries and frequency of financial crises have imposed high welfare costs on the countries involved. The empirical literature provides, at best, a mixed picture on the relationship between long‐run EM country growth and financial integration. Meanwhile, the prevailing policy discourse regarding reform of the international financial system remains incomplete: the focus has largely been on either institutional and policy measures required of EM countries or international crisis‐resolution procedures. The role played by private financial markets and institutions in the developed world has not received adequate attention. This paper describes some of the structural features inherent in today's financial markets that directly contribute to the instability in EM capital flows.     

THE BENEFITS OF USING E‐BUSINESS TECHNOLOGY: THE SUPPLIER PERSPECTIVE

The use of e‐business technologies between supply chain organizations has primarily been examined from the viewpoint of buying firms or retailers, with little attention given to the benefits accrued to suppliers. Further, previous studies have been limited to either financial or marketing performance measures, or a narrow range of operational measures. This study builds on research in this area by testing a model of the relationship between supplier use of e‐business technologies in communication with their primary buyer, degree of buyer‐supplier coordination, and a complete set of benefits that include strategic and operational performance measures. Using data from 241 first‐tier OEM suppliers in the computer industry, the findings show that supplier use of e‐business technologies positively impacts organizational benefits both directly and indirectly by promoting buyer‐supplier coordination.     

Driver Management That Drives Carrier Performance

The trucking industry provides the majority of transportation services in the United States. Truck drivers, particularly their driving performance, which influences how customers perceive motor carriers, are integral to the success of their firms. Hence, driver management is a topic of great interest to the trucking industry, logistics practitioners, and logistics researchers. Although the logistics literature does address issues relating to driver management, advice is scarce regarding how motor carriers might manage drivers to improve operational performance and thus the bottom line. Our results shed light on the processes whereby some formal controls directly influence operational performance, whereas others indirectly influence operational performance; that is, in the latter case, the influence of formal controls on operational performance is mediated by certain informal controls. According to our findings, motor carrier firms that employ a combination of formal and informal controls perform better operationally than firms that do not do so. And, thus, those employing such a combination of controls will realize a larger market share.     

An Empirical Investigation of the Relationship Between Change in Corporate Social Performance and Financial Performance: A Stakeholder Theory Perspective

Stakeholder theory provides a framework for investigating the relationship between corporate social performance (CSP) and corporate financial performance. This relationship is investigated by examining how change in CSP is related to change in financial accounting measures. The findings provide some support for a tenet in stakeholder theory which asserts that the dominant stakeholder group, shareholders, financially benefit when management meets the demands of multiple stakeholders. Specifically, change in CSP was positively associated with growth in sales for the current and subsequent year. This indicates that there are short-term benefits from improving CSP. Return on sales was significantly positively related to change in CSP for the third financial period, indicating that long-term financial benefits may exist when CSP is improved.     

The economic relationship between service quality and market protection for regulated household-goods moving

In considering the effects of motor carrier regulation, the direct measurement of service quality is an often neglected issue. This paper is an empirical investigation of the relationship of entry controls to service quality for household goods (HHG) moving services. The major research questions, which are based on inferences in the economic literature, have considerable importance for HHG regulation. The major finding is that carriers who receive the greatest market protection from the ICC provide inferior service quality and do not compete away excess returns by raising the level of service quality. Based on the study results, a number of theoretical and policy implications are discussed.
