In empirical corporate finance, firm size is commonly used as an important, fundamental firm characteristic. However, no research comprehensively assesses the sensitivity of empirical results in corporate finance to different measures of firm size. This paper fills this hole by providing empirical evidence for a “measurement effect” in the “size effect”. In particular, we examine the influences of employing different proxies (total assets, total sales, and market capitalization) of firm size in 20 prominent areas in empirical corporate finance research. We highlight several empirical implications. First, in most areas of corporate finance the coefficients of firm size measures are robust in sign and statistical significance. Second, the coefficients on regressors other than firm size often change sign and significance when different size measures are used. Unfortunately, this suggests that some previous studies are not robust to different firm size proxies. Third, the goodness of fit measured by R-squared also varies with different size measures, suggesting that some measures are more relevant than others in different situations. Fourth, different proxies capture different aspects of “firm size”, and thus have different implications. Therefore, the choice of size measures needs both theoretical and empirical justification. Finally, our empirical assessment provides guidance to empirical corporate finance researchers who must use firm size measures in their work.

Our study analyses 6 million civil judgments in China from 2014 to 2018, documenting gender disparities that disfavour female litigants. We investigate the impact of an open justice reform that mandated courts to broadcast legal proceedings live on a centralized online platform. By exploiting variations in its implementation across courts and over time and employing both difference-in-differences and Bartik IV approaches, we find that gender disparities in chances of winning decrease as broadcast intensity increases. Analysis of the textual content of judicial decisions provides further evidence that these changes in judicial outcomes stem from altered judge behaviours (i.e. attention and effort) under enhanced judicial transparency. Our results demonstrate how information technology shapes judges’ conduct, underscoring its broader potential to improve accountability in public institutions.

We examine the association between CEO birthplace proximity and financial misconduct. We find that CEOs managing firms near their birthplaces (home CEOs) are associated with less financial misconduct compared to other CEOs. This association is not attributable to differences in corporate governance. The relationship strengthens in areas with a strong local investment presence and greater religious commitment as well as among CEOs with longer tenures in their home state. Our findings are robust to addressing potential selection and omitted variable biases as well as to conducting multiple robustness tests, including analyses of involuntary CEO changes and headquarters relocations. We also find a similar association for CFOs, with firms employing home CFOs exhibiting less financial misconduct.

We examine the relation between home CEOs and corporate social responsibility (CSR). Our analysis shows home CEOs are associated with higher CSR engagement and increased firm value. These firms exhibit higher asset turnover, lower cost of equity , improved productivity, sales, and profit margins. Home CEOs focus more on community, environmental, and employee-related CSR, and are linked to reduced carbon emissions . This relationship is stronger in firms with higher local business concentration and investor monitoring. Firms led by home CEOs earn higher returns during recent crises. Our results suggest the value increase is not primarily due to agency effects and remain robust to endogeneity concerns. The study indicates a CEO’s community connection may influence CSR effectiveness, suggesting that mere CSR engagement may not suffice to boost trust and value. These results highlight the potential importance of local ties in corporate leadership and CSR strategy.
