Revisiting the Idiosyncratic Volatility Puzzle in an Emerging Market: New Evidence from IndiaAuthor: Jyoti KumariArticle history:
Abstract (Click Here for Abstract)
This study re-examines the idiosyncratic volatility (IVOL) puzzle in an emerging market setting by investigating whether firm-specific risk is systematically priced in the cross-section of Indian equity returns. Using a comprehensive panel of 1,356 non-financial firms listed on the National Stock Exchange over 2000–2024, we implement a dual-measurement framework that distinguishes between unconditional IVOL, derived from a liquidity-augmented multifactor model, and conditional IVOL, estimated via an EGARCH specification to capture time-varying volatility dynamics. Employing both portfolio-sorting techniques and Fama–MacBeth regressions, we document a robust and economically significant positive IVOL–return relation, with substantially stronger pricing effects for conditional IVOL. These findings stand in contrast to the negative IVOL anomaly reported for developed markets and instead support theoretical models of incomplete diversification, limits to arbitrage, and behavioral mispricing in segmented markets. Further, we show that conventional factor models fail to subsume the predictive content of IVOL, particularly when volatility dynamics are explicitly modeled. The results suggest that idiosyncratic volatility in India proxies for a state-dependent, priced risk factor rather than diversifiable noise. Our findings contribute to the asset pricing literature by reconciling conflicting IVOL evidence through a unified framework and by highlighting the critical role of market frictions and conditional risk structures in emerging economies.

Determinants of Microfinance Institutions’ Profitability: A Systematic ReviewAuthor: Harkat Tahar, Ez-zarzari Zakaria, Aguenaou Samir, Jawad Abrache, and Mohamed BenyahiaArticle history:
Abstract (Click Here for Abstract)
While the main purpose of microfinance institutions (MFIs) is to provide the poorest segment of the population access to capital, it also aims at being profitable to ensure continuity. Achieving higher levels of profitability enables MFIs to achieve self-sufficiency and become less reliant on donors. For this, scholars and academics have been massively interested in identifying the main determinants that have a direct/indirect impact on MFIs’ profitability. However, given the diversity of findings and growing complexity of influencing factors, a systematic review is crucial to consolidate current knowledge, reveal consistencies and contradictions in the literature, and provide clarity on what drives profitability across varying contexts. In this regard, this contribution provides the state of the art by systematically reviewing the main determinants of MFIs’ profitability. The review distinguishes between firm-specific and non firm-specific determinants. Firm-specific factors include MFI characteristics (e.g., size, legal status, capital structure), loan portfolio variables (e.g., yield, risk), outreach levels, personnel productivity, and ESG strategies. Non-firm-specific determinants encompass macroeconomic variables, regulatory policies, market competition, and governance indicators. The analysis reveals that both internal and external factors significantly shape MFIs’ financial outcomes, but their impact varies based on regional, institutional, and temporal contexts. The findings have practical implications for MFI managers, donors, and policymakers to improve MFIs’ internal efficiency (e.g., optimizing loan structures and staff productivity) while adapting to external conditions (e.g., economic volatility and legal frameworks). The originality of this study lies in the identification of the various factors that influence the profitability of these institutions, uncovering literature gaps, and suggesting novel directions for future research.
