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.     

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.     

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.     

A New Look at the Longitudinal Relationship Between Motor Carrier Financial Performance and Safety

Motor carrier safety impacts the well‐being of the traveling public and the economic well‐being of the shippers who entrust motor carriers with safely transporting freight. Shippers are affected by motor carrier safety due to accidents damaging their cargo and disrupting their customers’ operations. One characteristic frequently theorized to predict motor carrier safety is motor carriers financial performance. However, the literature offers mixed evidence linking motor carrier financial performance to safety. This does not help practitioners or policy makers and necessitates research to resolve these inconsistent findings, which we undertake in this research. We extend previous work by developing a theoretical framework based on strain theory to explain why both absolute (static) financial performance and year‐to‐year change in financial performance should uniquely affect carrier safety. We test our hypotheses by fitting mixed‐effects models to a repeated‐measure, longitudinal database of publically traded motor carrier financial performance and safety measures. Results indicate that financial performance measures uniquely affect carrier safety. These findings attempt to resolve the inconsistencies in the past literature and, carry important implications for researchers studying motor carrier safety, motor carrier managers, shippers, and policy makers.     

Defining Ownership: An empirical assessment of the ownership measures

Ownership is considered to be one of the crucial governance mechanisms; however, there have been no systematic attempts at validating the construct and measures used to operationalize ownership. We review the current understanding of ownership and the measures used by each perspective, namely blockholder/dispersed shareholder perspective, owner identity perspective, and aggregated ownership perspective. We thereafter critique each of these perspectives, offer hypotheses regarding their validity, and empirically assess each ownership measure vis‐à‐vis firm performance outcomes. We utilize a sample of 3,990 US firms to test our hypotheses and find no consistent results for the blockholder measure, or for the owner identity measure. However, the aggregated ownership measure consistently accounts for significant increases in explanation of variance in firm performance. Copyright © 2018 ASAC.

DO ELECTRONIC LOGBOOKS CONTRIBUTE TO MOTOR CARRIER SAFETY PERFORMANCE?

Within the U.S. Department of Transportation and among U.S. motor carriers, there has been increased interest in the potential benefits of electronic logbooks to improve the safety of trucking operations. This paper investigates the specific contribution of electronic logbooks to improving firm safety performance (as measured by the number of crashes and hours of service violations). The models presented demonstrate that electronic logbooks contribute positively to crash reduction and to decreases in hours of service violations, particularly among carriers with poor overall safety records. Moreover, hours of service violations fully mediate the relationship between electronic logbook use and number of crashes. These results have policy significance as the Federal Motor Carrier Safety Administration has proposed a rule that would require the use of electronic logbooks for some carriers.     

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.     

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.     

The Effect of Truckload Driver Turnover on Truckload Freight Pricing

High rates of truck driver turnover have long plagued the full truckload (TL) sector. While greater driver turnover raises TL carriers’ costs, no research has examined how changes in industry-wide TL driver turnover rates affect industry-wide prices shippers pay for TL transportation. Drawing on economic theory regarding firms’ asymmetric adjustment of prices in response to changing costs, we explain why increases in driver turnover are expected to increase the prices carriers charge for their services, whereas decreases in driver turnover are expected to have limited effect on the prices carriers charge for their services. We further explain why the positive impact of increases in industry-wide TL driver turnover rates on prices will be more pronounced when industry employment is rising more rapidly. To test our theory, we assemble a time series data set combining proprietary driver turnover data with publicly available data regarding TL pricing, trucking employment, diesel prices, and aggregate industry activity. Results from fitting a set of time series econometric models corroborate our theorized predictions. We explain the implications of these findings for theory and practice.     

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.     

Organizational Learning Capability: Theoretical Analysis and Empirical Study in the Context of Official Development Aid Project Teams

Although several studies have investigated Organizational Learning Capability (OLC), the question of its operationalization remains open. We review the OLC concept, analyze its relationship to Organizational Learning (OL), and assess the validity of its operationalization through three models (formative, reflexive, mixed). While part of the literature states that OLC has five dimensions (experimentation, risk taking, dialogue, interaction with stakeholders, and participation in decision making), our exploratory study of 41 Official Development Aid projects suggests the existence of an important sixth dimension for OLC: autonomy vis‐à‐vis the national supervisor. The theoretical and practical implications of this finding are then discussed. Copyright © 2013 ASAC. Published by John Wiley & Sons, Ltd.     

The Information Use in a SME: Its Importance and Some Elements of Influence

The aim of this study is to gain some insights into the importance of the information use for the success of a SME. Consequently we examine some characteristics of the owner/manager and his firm which determine the extent of this use. The value of the model is examined for 208 Belgian SME owner/managers. Our data suggest there is a positive relation between the extent of information use and the performance of a SME. Moreover, we find that SME owner/managers with a greater strategic awareness, with less firm experience prior to the present position and with a greater desire for growth use more information. Also, smaller family ownership and intervention in strategic management, as well as greater delegation of decision making, lead to a higher information use.     

THE LAST MILE: AN EXAMINATION OF EFFECTS OF ONLINE RETAIL DELIVERY STRATEGIES ON CONSUMERS

The Internet has increased the level of importance of the end‐consumer market to transportation carriers. In two between subject experiments, carrier disclosure on retail merchant websites is examined as a strategic differentiation strategy. Predictions are offered concerning effects of carrier disclosure strategies on product delivery‐related expectations, consumer attitudes, and intentions to purchase a product online. Results from Study 1 reveal significant differences between disclosure and nondisclosure of the carrier for numerous product delivery‐related variables, as well as many differences between the six carriers examined in this first study. Study 2 extends these findings by showing that providing consumers with a choice of carrier leads to increased levels of satisfaction with the online experience and greater willingness to buy, relative to nondisclosure and disclosure strategies.     

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.     

Endogenous Property Rights in a Hold‐up Experiment

In a hold‐up experiment designed to test theoretical predictions following from Hart and deMeza and Lockwood regarding investment behavior, Sonnemans, Oosterbeek and Sloof (SOS) find only a partial confirmation of theory. According to SOS these deviations from standard theory can be explained by positive reciprocal behavior. In this paper, we replicate the experiment by SOS and add another group of treatments in which asset ownership is endogenized by auctioning off the assets. Our experiment shows that the results by SOS crucially depend on the ownership structure being exogenously assigned by the experimenter. We present experimental evidence that, by and large, corroborates the theoretical predictions made by Hart.

Owner Commitment and Relational Governance in the Privately-Held Firm: An Empirical Study

This paper examines owner commitment and relational governance in the privately-held firm. The proposed model goes beyond agency theory to include research on organization commitment and organization citizenship behaviors, as well as stewardship theory, organizational social capital theory, social identity theory and social exchange theory. Results support predictions of stewardship theory and organizational social capital theory that owner commitment and firm performance are positively related.      

The Dependence of Family Businesses on a Single Decision‐Maker*

Anecdotal evidence suggests that family businesses are very dependent on a single individual (the owner‐manager). However, the degree of dependence previously has not been studied formally. Further, an explanation for why some family businesses are highly dependent on the owner‐manager and others are not has not been explored. Utilizing a national survey of Canadian family‐owned businesses, this paper therefore addresses two central issues: (1) the degree of dependence of family‐owned businesses on a single individual; and (2) the factors associated with this reliance. Self‐report responses from family business owners provided evidence of a high level of dependence on the owner‐manager. In 75 percent of all family businesses, respondents believed that the company was either dependent or very dependent on them. The response to this subjective question is consistent with responses to our three more objective measures. First, 65 percent of owner‐managers responded that they made all the major decisions in at least three of five functional business areas. Second, these businesses had few key managers—in 57 percent of all businesses, there were only two or fewer key managers in addition to the owner. Third, in 62 percent of all family businesses, neither had a successor been chosen nor had a process been put in place for choosing a successor. These results strongly suggest that family businesses are highly dependent on a single individual. Six factors had significant power in explaining the degree of dependence. Two factors related to the owner‐manager—dependence decreased in the age of the owner‐manager and in proximity of the owner‐manager to retirement. Four factors related to the family business: dependence decreased in the value of the firm, the number of shareholders, and the age of the business and was greater where the owner‐manager's family had voting control. Surprisingly, neither the existence of a board of directors with outside membership nor an advisory board with outside membership helped explain the level of dependence.     

The role of certification in service relationships: Theory and empirical evidence

In this paper we draw upon multiple theoretical perspectives and develop a conceptual framework regarding the role of certification signals in service relationships. The central premise of this study is that sellers who use certification display for making promises also institute appropriate mechanisms for controlling service providers. Furthermore we hypothesize that the degree of certification display and agent screening is moderated by the relative costs of certification and screening respectively. We empirically test our model by analyzing data from a mail survey of automotive service managers. Our results support the theoretical notion that building customer relationships involves making and keeping promises in service delivery.
