Abstract

Purpose

The paper compares multi-period forecasting performances by direct and iterated method using Bayesian vector autoregressive (VAR) models.

Design/methodology/approach

The paper adopts Bayesian VAR models with three different priors – independent Normal-Wishart prior, the Minnesota prior and the stochastic search variable selection (SSVS). Monte Carlo simulations are conducted to compare forecasting performances. An empirical study using US macroeconomic data are shown as an illustration.

Findings

In theory direct forecasts are more efficient asymptotically and more robust to model misspecification than iterated forecasts, and iterated forecasts tend to bias but more efficient if the one-period ahead model is correctly specified. From the results of the Monte Carlo simulations, iterated forecasts tend to outperform direct forecasts, particularly with longer lag model and with longer forecast horizons. Implementing SSVS prior generally improves forecasting performance over unrestricted VAR model for either nonstationary or stationary data.

Originality/value

The paper finds that iterated forecasts using model with the SSVS prior generally best outperform, suggesting that the SSVS restrictions on insignificant parameters alleviates over-parameterized problem of VAR in one-step ahead forecast and thus offers an appreciable improvement in forecast performance of iterated forecasts.

Abstract

Purpose

The purpose of this study is to contribute to the debate on the impact of organizational culture and national culture on green supply chain management (GSCM) adoption by empirically testing the developed framework, and ultimately pave the way toward potential areas for future research.

Design/methodology/approach

Using survey data from a sample of Moroccan manufacturing firms, 130 responses were collected and analyzed using SPSS 25 and Smart PLS v 3.3.3 software. The paper used a convenience sample, as it is required by the quantitative method, which legitimate making generalization under certain conditions.

Findings

The research results indicated that the national culture does not influence the GSCM implementation. The results contradict a number of prior works. As for the second direct effect measured postulated that organizational culture has a direct and significant impact on the GSCM. The results indicate that adhocracy culture, clan culture and hierarchical culture have a positive impact on the implementation of GSCM initiatives. To assess the impact of ownership type on GSCM, we underlined the difference between local and foreign firms. In fact, as argued, the foreign firms are more implementing GSCM initiatives than local firms do. Based on the arguments advanced on prior literature, the firm size does, as expected, exert significant control over the adoption of GSCM initiatives.

Research limitations/implications

The paper here is a starting point to understand how environmental sustainability and culture are interlinked; further research might contribute to this topic by empirically testing the model in similar or different contexts, using different cultural frameworks.

Practical implications

The practical implications for the paper are related to the necessity of adopting adequate organizational culture to build responsible behaviors for GSCM adoption by Moroccan firms. Recognizing the powerful role of organizational culture as a crucial factor responsible for GSCM’s success beyond the well-defined corporate strategies, including market presence and technological advantages, etc.

Social implications

This paper contributes to the establishment of codependent links between sociology and management fields as it helps to update the social theories present in the operations management area.

Originality/value

To the best of the author’s knowledge, few works have pursued to review and bridge cultural theories with the GSCM implementation.

Abstract

Purpose

The purpose of this paper is to contribute to the understanding of the relationship between different types of organizational culture (hierarchical, clan or group, market or rational and adhocratic) and sustainability through three dimensions (economic, environmental and social) in ecotourism businesses in Oaxaca and Chiapas, Mexico.

Design/methodology/approach

In this research 80 questionnaires were administered in the form of face-to-face interviews to ecotourism business owners'. Through a discriminant analysis and the theoretical support of the competing values framework (CVF), the prevailing types of culture were identified, and their influence was analysed through a regression analysis.

Findings

The results show that ecotourism businesses which are driven by hierarchical culture tend to have a greater focus on economic sustainability, while those businesses with a market or rational culture show a positive and significant influence on environmental sustainability. Likewise, businesses with adhocratic culture achieve sustainability holistically; however, the data reveal that clan or group culture is not associated with social sustainability.

Originality/value

This study offers empirical research that explains the relationship between organizational culture and sustainability. Additionally, it contributes to the study of environmental management issues in the ecotourism sector.
