Abstract

Public procurement plays a pivotal role in driving economic development, particularly in developing nations like Ghana, where government spending accounts for a substantial 70% of the national budget, significantly impacting GDP. This study critically examines the impact of public procurement reforms, notably the Public Procurement Act of 2003 (Act 663) and its subsequent amendments, on Ghana's economic trajectory. These reforms were strategically implemented to enhance transparency, accountability, and efficiency in public resource management. Analysis of key indicators reveals a mixed landscape of outcomes. While the Act has demonstrably improved procurement processes, reduced instances of corruption by a significant 25%, and streamlined public spending efficiency by 15% over the past decade, persistent challenges remain. These include inadequate institutional capacity, inconsistent enforcement of legal frameworks, and limited stakeholder engagement, collectively hindering the full realization of the reforms' transformative potential. Employing a mixed-methods approach, including secondary data analysis and in-depth interviews with government officials, procurement professionals, and civil society representatives, this study provides critical insights. While procurement reforms have made tangible contributions to economic growth  evident in an estimated 10% annual savings in government expenditure significant enhancements are imperative in areas such as capacity building, regulatory enforcement, and fostering robust public-private collaboration. The study concludes with a set of actionable recommendations for stakeholders, including the imperative to strengthen institutional frameworks, promote ethical procurement practices, and cultivate inclusive stakeholder engagement. These measures are crucial for maximizing the impact of procurement reforms and ensuring sustainable economic development in Ghana.

Abstract

Purpose: This study aims to develop and validate the Adaptive Brand Ecosystem model, a new framework that integrates marketing intelligence with agile supply chain execution to enhance organizational responsiveness and competitiveness. It hypothesizes that tighter integration between marketing and operations leads to superior market performance and customer retention. Research Design and Methodology: The research employed a quantitative design using cross-sectional data from 214 companies across various global markets. Performance indicators such as response speed, inventory turnover, and customer retention were analyzed to measure the impact of marketing–supply chain integration. Additionally, case studies from Zara and Warby Parker were used to provide qualitative insights into real-world applications of adaptive capabilities. Findings and Discussion: The findings reveal that firms with strong marketing–operations integration respond 68% faster to market changes, achieve 28% higher inventory turnover, and retain 22% more customers than competitors. The analysis highlights how dynamic market-sensing capabilities restructure supply chains to translate consumer insights into operational advantages. Implications: The model provides executives with strategic guidance for building co-evolving marketing and supply chain systems and introduces tools such as the Demand Response Scorecard. For academics, theory advances by linking dynamic capabilities, market orientation, and operational flexibility, promoting a shift from market-responsiveness to market-propulsion.

Abstract

Purpose: A significant paradox undercuts artificial intelligence's promise in strategic marketing: while 92% of organizations already use AI-generated insights, 74% of executives distrust them for crucial decisions. Research Design and Methodology: This study addresses the credibility dilemma by conducting a groundbreaking blind test with 200 Chief Marketing Officers from Fortune 500 companies, analyzing identical business challenges—half answered by premier AI platforms (GPT-4 and custom LLMs), and half by experienced human analysts. Findings and Discussion: The technique found an unexpected discrepancy: whereas NLP assessment indicated AI matched or exceeded human report quality in 82% of cases, displaying higher predictive accuracy (+14%) and data comprehensiveness, executives rejected 68% of algorithmically generated insights. A multivariate study identified explanatory inadequacies as the crucial factor: AI's inability to communicate why patterns mattered (causal reasoning), base discoveries in operational realities (contextual framing), and structure insights coherently (narrative flow) accounted for 53% of the trust gap. This "analytics without understanding" dilemma was evident when CMOs ignored an AI report accurately predicting telecom churn because it overlooked how back-to-school tuition payments stretched household budgets—the explanation that made the helpful finding. The study proposes a hybrid approach that adds human-authored "why explanations" (about 47 words) to AI outputs, increasing adoption intent by 40% while maintaining 60% efficiency improvements. Implications: These findings suggest viewing algorithm aversion as a fundamental epistemic reconciliation challenge—one where narrative intelligence links computational power and human judgment. As AI affects strategic decision-making, this study gives a trust calibration plan for maximizing its potential while maintaining interpretative depth.
