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.     

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.     

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.     

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.     

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.     

Explanations for continued gender discrimination in South Korean workplaces

This paper investigates potential explanations for the continued gender discrimination in South Korean workplaces despite decades of gender policy reforms and improved education for women. Making use of both primary and secondary data sources, the institutional theory, the voluntary compliance regulatory enforcement strategy and the typology of regulatory noncompliance provide a framework from which four explanations regarding the origin and nature of Korean firm equal opportunity (EO) compliance issues are derived. Identified through data analysis, explanations include a lack of legal enforcement, a weak punishment system, a tacit acceptance of the status quo by women, organizational cultural issues stemming from the traditional Korean mind-set that allow gender discrimination and a general lack of knowledge about EO regulations by many companies. Reforms and paradigm changes addressing these gender policy compliance issues could yield considerable social benefits in reducing the scope and quantity of gender discrimination in Korean workplaces.     

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.     

The effect of geographic scope on growth and growth variability of SMEs

The impact of international expansion on the success of small and medium enterprises (SME) has been extensively studied, particularly with respect to the performance implications of expansion into foreign markets. Yet, the literature is still unclear on the consequences of the SME's geographic scope (i.e., the number of countries a firm operates in). Drawing on the contemporary internalization theory, we build a theoretical framework suggesting that SMEs’ geographic scope positively impacts firm growth rate, yet makes it less reliable, i.e., a positive effect on both the mean and the variability of growth. We also suggest that this relationship is highly context-dependent. The positive benefits of the increasing scope materialize only when the firms can manage the rising complexity of operational governance through leveraging the managerial international competencies (obtained, e.g., through international education and international experience) and constraining the geographic expansion to their home region. The framework is empirically tested on data from Swiss SMEs engaged in international operations, employing the multiplicative heteroscedasticity regression model specification with endogenously modeled scope.

Modelling risk factors for fatal pedestrian crashes in Kolkata,India

Abstract

In developing countries, pedestrian safety is an issue of major concern. Although an extensive body of literature is available on the identification of elements related to the pedestrian’s risk; the studies are primarily conducted in urban areas of developed countries. The findings from these studies may only be partially relevant to the cities of an emerging country such as India. The present study analyzes historical crash records obtained from the “Kolkata Police” and identifies the risk factors at the road network level for the hazardous corridors posing a high risk to the pedestrians. The study findings reveal that pedestrians’ fatalities at intersections are associated with a high vehicular volume, higher pedestrian-vehicular interaction, high approach speed, overtaking tendency of vehicles, certain land-use type, encroachment of footpath, inadequate sight distance, inaccessible pedestrian crosswalk, wider minor carriageway, the absence of a pedestrian signal head, and lack of enforcement. On the other hand, the models outcomes reveal that pedestrians’ fatalities at midblock road segments are associated with low pedestrian volume, high approach speed, overtaking tendency of the vehicle, encroachment of footpath, on-street parking, wider road width, certain land-use type, inadequate sight distance, insufficient lighting, and inadequate pavement markings.     

Does parasocial interaction with weight loss vloggers affect compliance? The role of vlogger characteristics,consumer readiness,and health consciousness

Drawing on the notion of parasocial interaction (PSI) and the social comparison theory, this experimental research examines how nutritionist video bloggers (vloggers) influence consumer compliance intentions toward healthy, weight-loss diets. Drawing on two samples (Mexican Americans and White Caucasians) and using structural equation modeling and mediation analysis, this research highlights vloggers’ credibility and physical attractiveness, but not homophily, as salient source characteristics that influence PSI, which in turn reinforces compliance intention. Moreover, consumer readiness, consisting of role clarity, ability, and motivation, serves as a partial mediator of the PSI–compliance intention relationship. Lastly, consumer health consciousness emerged as a significant moderator of the PSI–compliance intention relationship among White Caucasians, but not among Mexican Americans. The findings and their implications are discussed.     

Selective Engagement in Corporate Social Responsibility: A Stakeholder Perspective

This paper attempts to understand selective engagement in corporate social responsibility (CSR). CSR involves various issues that can meet demands from multiple stakeholders. A firm can focus on certain CSR issues to satisfy a particular stakeholder while ignoring the demands from other stakeholders, or it can take a more balanced approach to CSR by addressing a wider range of social issues. In this paper, I investigate how stakeholder pressures from three types of primary stakeholders (customer, supplier, and employee) shape selective engagement in CSR. The empirical results based on a representative sample of more than 1,000 small and medium-sized enterprises (SMEs) in the early 2000s suggest that firms prioritize their stakeholders based on instrumental considerations. Those stakeholders who have greater power over the focal firm will exert a larger impact on a firm’s CSR engagement. Constrained by limited managerial resources, firms accord attention to a limited range of issues most relevant to salient stakeholders. Specifically, MNCs as major customers pressure the focal firm to assume more responsibility for product quality, as well as on a wider range of social issues; SOEs as both major customers and major suppliers pressure the focal firm to assume more responsibility for employee welfare; employees with higher education pressure the focal firm to assume more responsibility for employee welfare, and for a wider range of social issues. This study contributes to stakeholder theory and research on the CSR of SMEs, and has important implications for CSR practitioners.     

Use of tobacco retailer inspections to reduce tobacco sales to youth: do inspections increase retailer compliance?

Public health efforts to prevent tobacco use among young people have typically attempted to change individual behaviour. More recently, it has become evident that macro‐level behaviour change strategies which impact on the wider social environment are more effective in changing behaviour. In most states, retailer compliance laws restrict the sale and distribution of tobacco products to minor consumers. Indiana's Tobacco Retailer Inspection Program (TRIP), a state government programme, was established to put environmental controls in place by restricting youth access to tobacco products. TRIP involved conducting random, unannounced tobacco retailer outlet inspections, with violators being fined, and compliant retailers rewarded. This study examines the associations among retailer inspections, retailer compliance and access to tobacco by youthful consumers. Inspection data from 2001 to 2003 were analysed using chi‐square statistics and analysis of variance. Findings indicate that randomly selected retail outlet inspections are associated with increased sales restrictions to youth. The researchers conclude that strong tobacco sales regulations and enforcement will reduce illegal sales of tobacco products to minors.     

Leader narcissism and outward foreign direct investment: Evidence from Chinese firms

Researchers use the upper echelons theory to establish how leaders’ attributes affect firms’ outward foreign direct investment (OFDI), a proxy for foreign operations. This extant literature has largely ignored the impact of leaders’ psychological attributes, particularly, narcissism. We use a narcissism index of leaders of Chinese listed companies to examine the relationship between leader narcissism and firm-level OFDI for the period 2007-2017. We show that leader narcissism has a positive and significant impact on firm-level OFDI. In addition, we find that firms with state ownership and political connections show a greater positive effect of leader narcissism on the firm’s OFDI. Our results suggest that leader narcissism appears to be a stimulus to corporate OFDI, and thus in recruiting top corporate executives who are responsible for managing the international investments of the corporation, this psychological trait should be given special consideration in addition to other qualifications.     

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.     

Rewards that undermine customer loyalty? A motivational approach to loyalty programs

Guided by the framework of self‐determination theory (SDT), this study examined the effects of external rewards on undermining customers’ intrinsic motivation to engage in a retail loyalty program. Two experiments revealed that participants who received a salient, controlling reward (i.e., a promise of reward with an explicit requirement and deadline, without options of choice) reported lower intrinsic motivation to use the loyalty program than participants who received a nonsalient, autonomy‐supportive reward (i.e., a promise of reward with a less explicit requirement and no deadline, with options of choice). However, the undermined intrinsic motivation of those who received the salient, controlling reward was enhanced when they were given verbal feedback acknowledging their potential negative feelings associated with using the loyalty program. These findings provide important practical implications for designing a more effective loyalty program.     

Why the Doctor Will NOT See You Now: The Ethics of Enforcing Covenants Not to Compete in Physician Employment Contracts

When a physician employment relationship terminates, the physician–patient relationship may also be terminated by enforcement of a covenant not to compete, which typically forces the physician to leave the geographic area for a period of time. This gives rise to several ethical dilemmas. The public interest is compromised when enforcement of these covenants contributes to the shortage of physicians in the community, and individual patients are harmed when their physicians are no longer available. The authors undertook a unique study to explore physician perspectives concerning the ethics of banning a physician from practice and the impact of the ban on both the physician and the physician’s patients. The results identified harmful effects that have not been raised in prior scholarly articles or reported court opinions. After reviewing the legal background of covenants not to compete, this paper presents the results of that study and concludes that resorting to the legal system for enforcement of covenants not to compete is not always the ethical course of action.

Out of the frying pan and into the fire? Uncovering the impact of FSMA’s sanitary food transportation rule on the food logistics industry

Public policy affects businesses in several ways, yet its intersection with the food logistics industry is not well understood. This article explores the case of the Sanitary Transportation of Human and Animal Food Rule—enforced in 2018—and its impact on the food logistics industry. It is one of the most significant rules of the U.S. Food Safety Modernization Act and, in many ways, improves the rulebook for U.S. food haulage. The objective is to prevent food contamination during transportation by establishing vehicle design and maintenance requirements, safe transportation operations, transit temperature controls, carrier personnel training, and record-keeping. The Sanitary Transportation of Human and Animal Food Rule also transforms the roles and responsibilities of traditional industry stakeholders (i.e., brokers, shippers, carriers, loaders, and receivers) and creates unique challenges for them. This article works to develop an understanding of stakeholders’ evolved roles via the salience model, identify challenges, and suggest relevant solutions, including a compliance checklist for each stakeholder.
