Abstract

Purpose

Research on effort-reward “imbalance” (ERI) has gained popularity in the occupational health literature, and authors typically use effort-reward ratios (ERRs) to study this phenomenon. This article provides a methodological and theoretical critique of this literature and suggestions on how future research can better study joint effects of efforts and reward.

Design/methodology/approach

The authors conducted a simulation study, analyzed panel data and surveyed the literature on the theoretical and methodological basis of the “imbalance” concept.

Findings

The simulation study indicates that under many conditions the ERR captures main effects of effort and reward and that effects also depend on the scaling of the variables. The panel data showed that when main effects and the interactions of effort and reward are entered simultaneously in a regression predicting mental and physical health, the significant effect of the ERRs disappears. The literature review reveals that psychological theories include more elaborate theoretical ideas on joint effects of effort and reward.

Research limitations/implications

The results suggest that moderated multiple regression analyses are better suited to detect a misfit between effort and reward than ERRs. The authors also suggest to use the term effort-reward fit in future research.

Originality/value

Methodologically and conceptually the authors showed that the ERR is not an appropriate approach because it confuses main effects with interaction effects. Furthermore, the concept of ERI is better substituted by a broader conceptualization of effort-reward fit that can be integrated with the existing literature on person-environment fit. Recommendations for future research are provided.

Abstract

Purpose

Experiencing more frequent, system-wide disruptions, such as pandemics and geopolitical conflicts, supply chains can be largely destabilized by a lack of materials, services or components. Supply chain resilience (SCRES) constitutes the network ability to recover after and survive during such unexpected events. To enhance the understanding of SCRES as a system-wide quality, this study tests a comprehensive SCRES model with data from multiple industries.

Design/methodology/approach

The study proposes a theoretical framework conceptualizing SCRES as system quality, extending the classical proactive/reactive taxonomy by multiple system states consisting of the supply system properties, behaviors and responses to disruptions. Underlying hypotheses were tested using an online survey. The sample consists of 219 responses from German industries. Maximum likelihood structural equation modeling (ML-SEM) and moderation analysis were used for analyzing the survey data. The study was particularly designed to elaborate on supply chain theory.

Findings

Two pathways of parallel SCRES building were identified: proactive preparedness via anticipation and reactive responsiveness via agility. Both system responses are primarily built simultaneously rather than successively. The present study further provides empirical evidence on the central role of visibility and velocity in achieving comprehensive SCRES, while flexibility only exerts short-term support after a disruption. The study additionally points to potential “spillover effects” such as the vital role of proactive SCRES in achieving reactive responsiveness.

Originality/value

The present study confirms and expands existing theories on SCRES. While stressing the multidimensionality of SCRES, it theorizes the (inter-)temporal evolution of a system and offers practical guidelines for SCRES building in various industrial contexts. It thus supports the transformation toward more resilient and viable supply chains, contributing to the increasing efforts of middle-range theory building to achieve an overarching theory. The study also points to potential future research avenues.
