This article makes two important contributions to the literature on the incentive effects of insider ownership. First, it presents a clean method for separating the positive wealth effect of insider ownership from the negative entrenchment effect, which can be applied to samples of companies from the US and any other country. Second, it measures the effects of insider ownership using a measure of firm performance, namely a marginal q, which ensures that the causal relationship estimated runs from ownership to performance. The article applies this method to a large sample of publicly listed firms from the Anglo-Saxon and Civil law traditions and confirms that managerial entrenchment has an unambiguous negative effect on firm performance as measured by both Tobin's (average) q and our marginal q, and that the wealth effect of insider ownership is unambiguously positive for both measures. We also test for the effects of ownership concentration for other categories of owners and find that while institutional ownership improves the performance in the USA, financial institutions have a negative impact in other Anglo-Saxon countries and in Europe.

We develop a Clawback Strength Index and show that while some firms adopt unambiguous and strong clawback provisions, others adopt weak ones. We find that strong clawback adopters experience improvements in financial reporting quality, fewer CEO turnovers, and lower CEO pay. We advance two possible explanations: First, clawback strength may be primarily responsible for the improvements in reporting quality. Second, strong clawbacks may yield benefits because they are part of a broader reform package. While our findings on reporting quality and CEO turnover are consistent with both explanations, our results on CEO pay support only the broader reform explanation.

A central issue in evaluating the effects of firm-level corporate governance (FLCG) is how to measure it. We focus here on emerging markets (EMs). One common approach to measuring FLCG uses country-specific (CSIs), tailored to each country's laws and institutions. Several studies report that CSIs can predict firm outcomes in a panel data framework with two-way (firm and time) fixed effects (TWFE). An alternate approach uses commercial CG ratings (CCGRs) that apply the same or similar elements across many countries. We assess the three best available CCGRs covering EMs (Asset4, Thomson Reuters, and MSCI), and find that they do not predict firm outcomes with TWFE in EMs. We also provide evidence that the likely cause for CCGRs' lack of performance is their poor construction rather than the inability of FLCG measures to predict outcomes. CSI-based studies suggest that disclosure (beyond country-mandated minimums) is the FLCG aspect that most consistently predicts firm outcomes in EMs. Yet, these CCGRs have no or minimal measures of disclosure. Other important limitations of the CCGRs include the use of elements that are U.S.-centric; reflect firm outcomes rather than CG; are implausible measures of good FLCG, or are vaguely or subjectively defined. We also attempt, but fail, to use element-level information from CCGRs to construct sound measures of FLCG.
