Abstract
Purpose
The paper provides a detailed historical account of Douglass C. North's early intellectual contributions and analytical developments in pursuing a Grand Theory for why some countries are rich and others poor.
Design/methodology/approach
The author approaches the discussion using a theoretical and historical reconstruction based on published and unpublished materials.
Findings
The systematic, continuous and profound attempt to answer the Smithian social coordination problem shaped North's journey from being a young serious Marxist to becoming one of the founders of New Institutional Economics. In the process, he was converted in the early 1950s into a rigid neoclassical economist, being one of the leaders in promoting New Economic History. The success of the cliometric revolution exposed the frailties of the movement itself, namely, the limitations of neoclassical economic theory to explain economic growth and social change. Incorporating transaction costs, the institutional framework in which property rights and contracts are measured, defined and enforced assumes a prominent role in explaining economic performance.
Originality/value
In the early 1970s, North adopted a naive theory of institutions and property rights still grounded in neoclassical assumptions. Institutional and organizational analysis is modeled as a social maximizing efficient equilibrium outcome. However, the increasing tension between the neoclassical theoretical apparatus and its failure to account for contrasting political and institutional structures, diverging economic paths and social change propelled the modification of its assumptions and progressive conceptual innovation. In the later 1970s and early 1980s, North abandoned the efficiency view and gradually became more critical of the objective rationality postulate. In this intellectual movement, North's avant-garde research program contributed significantly to the creation of New Institutional Economics.

Abstract
Purpose
The debate about whether corporate reports should focus on numbers or narrative is long-standing. The recent push for business model information to be included in corporate reports has revitalised the debate. Many scholars suggest this constitutes a move towards narrative-based reporting. This study aims to investigate the debate and draws a comparison with the juxtaposition of the narrative and rational paradigms. This study also investigates how accountingisation influences the way business model information is presented in corporate reports.
Design/methodology/approach
This study analyses data from the financial and non-financial reports from 86 globally listed companies. This study first uses content analysis to code the data. This study then uses a partial least squares-structural equation model to test how accountingisation influences how firms report their business model information.
Findings
This study finds that accountingisation and a rational paradigm shape how companies present information about their business model in their financial and non-financial reports. This suggests that the dominance of quantitative measures in accounting affects even the presentation of narrative-based information. Despite the much-touted shift towards qualitative reporting, this study argues that companies find it difficult to cast off the yoke of a traditional numbers-based mindset.
Research limitations/implications
This paper contributes to the debate on numbers- versus narrative-based corporate reporting and the workings of narrative and rational paradigms. In it, this study lays out theoretical and empirical findings of accountingisation. This study also makes a case for freeing corporate reports from the shackles of an accountingisation mindset.
Originality/value
This study provides new insights into how companies report information about their business models and the influence of narrative and rational paradigms on financial and non-financial reporting.

Abstract
Purpose
This paper aims to develop a conceptual framework on how the representativeness heuristic operates in the decision-making process. Specifically, the authors unbundle representativeness into its building blocks: search rule, stopping rule and decision rule. Furthermore, the focus is placed on how individual-level cognitive and behavioral factors, namely experience, intuition and overconfidence, affect the functioning of this heuristic.
Design/methodology/approach
From a theoretical standpoint, the authors build on dual-process theories and on the adaptive toolbox view from the “fast and frugal heuristics” perspective to develop an integrative conceptual framework that uncovers the mechanisms underlying the representativeness heuristic.
Findings
The authors’ conceptualization suggests that the search rule used in representativeness is based on analogical mapping from previous experience, the stopping rule is the representational stability of the analogs and the decision rule is the choice of the alternative upon which there is a convergence of representations and that exceeds the decision maker's aspiration level. In this framework, intuition may help the decision maker to cross-map potentially competing analogies, while overconfidence affects the search time and costs and alters both the stopping and the decision rule.
Originality/value
The authors develop a conceptual framework on representativeness, as one of the most common, though still poorly investigated, heuristics. The model offers a nuanced perspective that explores the cognitive and behavioral mechanisms that shape the use of representativeness in decision-making. The authors also discuss the theoretical implications of their model and outline future research avenues that may further contribute to enriching their understanding of decision-making processes.

Abstract
Purpose
Green consumption is fundamental to sustainable development, as it involves adopting practices and technologies that reduce the environmental impact of human activities. This study aims to analyze the influence of consumers’ green orientation on their environmental concerns and green purchase decisions. Furthermore, the study investigates the mediating role of consumers’ environmental concerns in the relationship between pro-sustainable orientation and green purchase decisions.
Design/methodology/approach
This study uses a quantitative methodology, applying the partial least squares method to a sample of 927 Portuguese consumers of green products. The sample was collected through an online survey.
Findings
Perceived benefits and perceived quality of products play a positive and significant role in influencing green behavior, especially when consumers are endowed with greater environmental concerns. In addition, consumers’ awareness of the prices of green products and their expectations regarding the future benefits of sustainable consumption positively impact green consumption behavior, further intensifying their environmental concerns.
Practical implications
According to the present findings, companies should adopt a holistic and integrated approach to promote green consumption. This means creating premium eco-friendly products, communicating their benefits, addressing the cost factor, emphasizing the future impact of eco-friendly options and raising consumers’ environmental awareness.
Social implications
It is critical that environmental education is a priority in schools and that there are political incentives for green behaviors. In addition, media campaigns can be an important tool to raise awareness in society.
Originality/value
The results of this study provide important insights for companies on consumer engagement in the circular economy. Deepening knowledge of the antecedents of consumers’ environmental concerns contributes to a deeper understanding of green purchasing decision behavior, allowing companies to support new business strategies.

The purpose of this paper is to facilitate a deeper understanding of the uses and users of performance measurement (PM) in the university context.
Abstract
Purpose
The purpose of this paper is to facilitate a deeper understanding of the uses and users of performance measurement (PM) in the university context.
Design/methodology/approach
Empirical data were gathered from four universities. This approach allows for a multilevel and comparative analysis based on the neo-institutional theory. The results are discussed alongside interdisciplinary literature on the use of PM in the public sector.
Findings
PM practices at universities have become increasingly popular on institutional, organisational and individual levels. The results indicate that different types of PM are used in universities and that the extent, and scope of PM used by various actors differ. Universities often use PM in a ceremonial and symbolic manner, with the aim of legitimising themselves externally as research-oriented institutions. The use of PM depends on both, exogenous factors (such as isomorphic pressures) and endogenous factors related to the different responses of organisations and individual actors (university managers, and academics). However, the analysis at the internal level reveals different attitudes and some resistance to the use of such kinds of PM. In universities with a local focus, the use of PM for rational decision-making is generally loosely coupled with the reporting performance for external accountability purposes. Moreover, the internal use of PM can be also symbolic.
Research limitations/implications
This paper focusses on four case studies that are currently undergoing changes. The comparative analysis is supported by the use of different data collection methods and several in-depth interviews with key university actors.
Originality/value
The authors assume that the use of PM depends on a number of exogenous and endogenous factors. PM uses and users are discussed in the specific context of the higher education system in Poland. The four business school cases facilitate a comparative analysis of the similarities and differences in terms of the uses and users of PM in the context of internationally and locally oriented universities.

Abstract
Purpose
The purpose of this paper is to compare two brand posts with the different content created by a celebrity (emotional content vs rational content) on Instagram and their effects on users’ willingness to use offline word of mouth (WOM) and electronic WOM (eWOM). The research model also consists of product involvement as the moderator.
Design/methodology/approach
Based on the results of the pretest stages, the study included two stimuli, and respondents were presented with two different brand posts (i.e. two manipulated pictures and texts on the Instagram frame). A two-group comparison (positive emotional brand post vs negative rational brand post) between-subjects experiment (n = 214) was conducted.
Findings
The results indicate that WOM and eWOM are more affected by a celebrity’s emotional brand post than a celebrity’s rational brand post. Furthermore, both types of WOM are more affected through high product involvement enhanced by a celebrity’s rational brand post than through high product involvement boosted by a celebrity’s emotional brand post.
Practical implications
Managerial implications for social media marketing and Instagram celebrity-based branding are provided. Practical implications are also provided in the form of evidence of how the impacts of two different brand posts on positive offline WOM and eWOM are affected differently through the moderation of product involvement.
Originality/value
The research argues for theoretical implications for the marketing literature on celebrity endorsements. The study also tests one moderating effect on the relationship between brand post content and WOM and eWOM.
Propósito
El propósito de este trabajo es comparar dos posts de marcas con diferente contenido creado por una celebridad (contenido emocional vs. contenido racional) en Instagram y sus efectos en la disposición de los usuarios a utilizar WOM y eWOM. El modelo de investigación también incluye la implicación del producto como moderador.
Diseño
Sobre la base de los resultados de las etapas de prueba previa, el estudio incluyó dos estímulos, y a los encuestados se les presentaron dos publicaciones de marca diferentes (es decir, dos imágenes y textos manipulados en el marco de Instagram). Se realizó un experimento entre sujetos (n = 214) de comparación de dos grupos (post de marca emocional positivo frente a post de marca racional negativo).
Conclusiones
Los resultados indican que el WOM y el eWOM se ven más afectados por el post emocional de la marca de un famoso que por el post racional de la marca de un famoso. Además, ambos tipos de boca a boca se ven más afectados por la alta implicación del producto potenciada por el post racional de la marca de un famoso que por la alta implicación del producto potenciada por el post emocional de la marca de un famoso.
Implicaciones prácticas
se ofrecen implicaciones de gestión para el marketing en las redes sociales y el branding basado en los famosos de Instagram. Las implicaciones prácticas también se proporcionan en forma de evidencia de cómo los impactos de dos publicaciones de marca diferentes en el WOM positivo y el eWOM se ven afectados de manera diferente a través de la moderación de la implicación con el producto.
Originalidad
La investigación aporta implicaciones teóricas para la literatura de marketing sobre el patrocinio de los famosos. El estudio también prueba un efecto moderador en la relación entre el contenido de los posts de marca y el WOM y el eWOM.

Abstract
Purpose
This paper is motivated by the need to assess the risk profiles associated with the substantial number of items within military supply chains. The scale of supply chain management processes creates difficulties in both the complexity of the analysis and in performing risk assessments that are based on the manual (human analyst) assessment methods. Thus, analysts require methods that can be automated and that can incorporate on-going operational data on a regular basis.
Design/methodology/approach
The approach taken to address the identification of supply chain risk within an operational setting is based on aspects of multiobjective decision analysis (MODA). The approach constructs a risk and importance index for supply chain elements based on operational data. These indices are commensurate in value, leading to interpretable measures for decision-making.
Findings
Risk and importance indices were developed for the analysis of items within an example supply chain. Using the data on items, individual MODA models were formed and demonstrated using a prototype tool.
Originality/value
To better prepare risk mitigation strategies, analysts require the ability to identify potential sources of risk, especially in times of disruption such as natural disasters.

Abstract
This paper introduces a monopolistic competition model containing retail investors with imperfect knowledge and issuers offering complex structured products. The model, for which we provide empirical evidences supporting the issuer’s profiteering by increasing the product complexity, can explain that knowledge asymmetry is the key for the issuer to offer complex product and to enjoy the higher excess profit, thus worsening allocative efficiency. Our empirical analysis reports monotonically increasing mark-up premia, and J-shaped issue amounts with respect to complexity: the former result could be explained in a rational framework considering issuer costs, however, the latter is not the case. Our model proves the empirical results are well explained when knowledge asymmetry between issuer and investors is a strictly increasing convex function of complexity.

Abstract
Purpose
The purpose of this paper is to lay down the methodological structure of the epistemology of tawhid (Oneness of Allah). In this paper, the meaning of tawhid also refers to the monotheistic unity of knowledge (consilience) in the cast of its organic pairing by circular causation relations between the moral and material possibilities. The paper thereby raises the critique of mainstream economic reasoning and its imitation by existing Islamic economics. Consequently, by the ontological, epistemological and phenomenological foundation of tawhidi methodological worldview, an altogether new socio-scientific reasoning in generality and economic reasoning in particular is introduced.
Design/methodology/approach
The socio-scientific methodological reasoning of unity of knowledge according to the tawhidi methodological worldview is introduced contrary to the inept rational choice postulates of mainstream economic reasoning and its imitation by existing notions of Islamic economics. The method of instructing students in the light of this approach according to Tawhidi Islamic Economics (TIE) is introduced from the existing literature.
Findings
The existing nature of mainstream economics and its imitation by Islamic economics is critically deconstructed and replaced by the true epistemological, ontological and phenomenological perspectives of TIE in the world of learning. Some inner properties of such a methodological study of TIE are laid bare for further investigation.
Originality/value
This is the first paper of its kind in this journal to expound the original and most creative methodological worldview that Islamic economics must bear. This is the foundation of the development of the true stance of Islamic economics and finance.
