This study investigates the effect of economic policy uncertainty on the firm profitability through moderating role of logistics infrastructure index using US non-financial firms listed at NASDAQ.

We used secondary data set which includes firm-level indicators of 2,323 non-financial US firms listed at NASDAQ over the period of 1998–2018. Ordinary least squares regression with multiple fixed effects used to analyze the data and estimate hypotheses.

The results show that economic policy uncertainty negatively impacts the firm’s profitability whereas the logistics infrastructure positively moderates the negative impact of EPU on the firm’s profitability.

Economic policy uncertainty is a significant challenge for managerial decision making and a direct threat to a firm’s profitability. The results of this study imply that the state of logistics infrastructure must be considered as an important policy tool by the senior management to mitigate the negative impact of economic policy uncertainty and to safeguard a firm’s profitability.

This study highlights that logistic infrastructure plays an important role in alleviating the adverse effect of economic policy uncertainty on the profitability of a US non-financial firm.

This study explores the interplay between economic policy uncertainty (EPU) and corporate investment, with a focus on how corporate diversification influences this relationship based on a diverse sample of developed and emerging 22 countries firms from year 2000–2020 investment.

This study uses the ordinary least square regression method with year, industry, country fixed effect. Also, robustness tests including two stage least square, propensity score matching, subsampling analysis applied to support the main findings.

Grounded in the real options perspective and financial constraints theory, the research reveals that diversified firms mitigate the adverse impact of EPU on corporate investment. Empirical findings from a sample of listed firms across 22 countries (2000–2020) demonstrate that, during high EPU, companies generally limit investment, in line with the real options perspective. However, diversified firms show a reduced negative impact highlighting diversification’s moderating role. Notably, sub-sampling analysis indicates that the moderating impact of corporate diversification is more pronounced in developed economies than emerging economies with related diversification measure and vice versa with unrelated diversification measure.

This research highlights the strategic significance of corporate diversification in alleviating the effects of economic uncertainty, with implications for both developed and emerging economies’ firms’ strategic decision-makers.

Our study is the first which highlighted the role of corporate diversification between economic policy uncertainty and firm investment based on 22 emerging and developed economies from around the world.

Small and medium enterprises (SMEs) are engines of economic growth. Research indicates that the adoption of green procurement practices (GPPs) significantly influences the sustainable growth of SMEs. However, there is a lack of understanding of factors that link the adoption of GPPs with enhanced competitiveness. The purpose of this study is two-fold: first, to identify factors that affect the competitiveness of SMEs caused by adopting GPPs, and second, to test those factors whether they serve as necessary conditions in achieving that competitiveness.

A quantitative approach was used to survey 188 manufacturing SMEs in Pakistan. Cross-sectional data was collected through online questionnaires and analyzed using structural equation modelling (PLS-SEM) and necessary condition analysis (NCA).

Results indicate a less pronounced direct association between the adoption of GPPs and firm competitiveness. However, this association becomes strongly positive with the mediating roles of SSB and GI. On the other hand, NCA results reveal that the adoption of GPPs, SSB and GI acts as necessary conditions for achieving firm competitiveness.

This research highlights the fact that simply adopting GPPs is not sufficient to guarantee true competitiveness; a multifaceted approach is required. Moreover, it offers practical insights into effective planning of green investments leading to sustainable development.

Various practical measures can be adopted to manage the social outcomes of investment in the adoption of GPPs by SMEs.

This study relates and contributes to the natural resource-based view (NRBV) theory, the stakeholder theory and the necessity theory by developing a novel analytical framework.
