The chapter discusses how mergers and acquisitions (M&A) affect business growth specifically accounting measures such as return on assets (ROA), return on equity (ROE), and realization of synergy. The research blends quantitative data from multiple industries with qualitative input from industry leaders to identify the successes and challenges of post-merger integration. However, the results show that—and this is hardly a surprise—mergers seldom create shareholder value without difficulties, especially regarding cultural integration and realization of expected synergies. There are widely diverging outcomes from sector to sector, and deal size is a key determinant of price. In this analysis, the authors take two distinct theories – the resource-based view (RBV) and synergy theory. Emerging literature on resource-based view (RBV) argues that M&A allows firms access to and effective deployment of resources, sources of sustainable competitive advantage.

This study investigates the behavioral elements that shape investor decision-making, particularly in the context of stock market investments supported by accounting information systems (AIS). Behavioral finance has emerged as an important field that examines how psychological traits and cognitive shortcuts influence financial judgments, challenging the assumption of purely rational investor behavior. The study gathered data from 270 retail investors and examined their responses utilizing SPSS and AMOS software. Advanced statistical methods, such as confirmatory factor analysis (CFA) and structural equation modeling (SEM), were utilized to examine the correlations among variables. The results indicate that psychological factors, including emotions, attitudes, moods, personality traits, and heuristic-based decision-making, profoundly influence investment behavior. Furthermore, the findings validate that these determinants persist in influencing investor decisions, even in the presence of dependable financial data disseminated via AIS. This work offers theoretical and practical contributions by integrating insights from behavioral finance and accounting systems research. It contributes evidence to the expanding body of literature that synthesizes human psychology with financial technology. The results provide direction to investors, financial institutions, and policymakers on mitigating biases and fostering more rational investment strategies through the appropriate utilization of AIS.
