Boissel and Matray (2022) find that investment increased after 2013 in French firms facing higher dividend taxes. We identify an alteration in the code plotting the event study of the effect of this reform on investment. Using identical data and removing this alteration, we find differential pre-trends between treated and control firms. We also establish that the controls referred to as "size growth," used in all the difference-in-difference specifications, effectively are controls for lagged investment, i.e., the main outcome variable. Removing such controls attenuates differential pre-trends but leaves no clear event study evidence of a positive effect of dividend taxation on investment.

We estimate the impact of French town hall elections held in mid-March 2020 on the mortality of 160,000 male candidates aged above 60. Their excess mortality during March and April was similar to the general population. We compare candidates in cities with two candidate lists to those in cities with only one list, as elections are more intense in contacts in the former group. We also use a regression discontinuity design and investigate mortality in 2020 depending on how candidates fared in the 2014 election. We cannot detect any causal effect of active participation in the 2020 elections on mortality. 

We investigate wealth returns on an administrative panel containing the disaggregated balance sheets of Swedish residents. The expected return on household net wealth is strongly persistent, determined primarily by systematic risk, and increasing in net worth, exceeding the risk-free rate by the size of the equity premium for households in the top 0.01%. Idiosyncratic risk is transitory but generates substantial long-term dispersion in returns in top brackets. Systematic and idiosyncratic risk both drive the cross-sectional distribution of the geometric average return over a generation. Furthermore, wealth returns explain most of the historical increase in top wealth shares.

We show that close votes on shareholder proposals are disproportionately more likely to be won by management than by shareholder activists. Using a sample of shareholder proposals from 2003 to 2016, we uncover a large and discontinuous drop in the density of voting results at the 50% threshold. We document similar patterns for say on pay votes and director elections. Our findings imply that shareholder influence through voting is limited by managerial opposition. It also follows that one cannot routinely use an RDD to identify the causal effects of changes in corporate governance generated by shareholder votes.

This paper assesses how CEO transitions shape labor contracts within firms. We argue that family links between a new CEO and his predecessor act as a commitment device for upholding implicit contracts with the workforce. Consistent with this view, we find evidence of a wage insurance mechanism during a CEO transition. Dynastically-promoted CEOs relative to external CEOs are associated with up to 25% less job separations and 20% lower wage growth. Crucially, we show that differences, in terms of job separations, between dynastic and non-dynastic CEO successions are significantly greater when labor markets are more frictional.

I ask whether public financial aid reduces small businesses’ credit constraints. To answer the question, we analyze a policy of bank loans made from subsidized funds. Extensions of this large program are plausibly exogenous and help identify its effects. Using firm-level data, we find that the program substantially increases debt financing without substitution between subsidized and unsubsidized finance. Returns on subsidized debt are significantly above its market cost, with no subsequent surge in default risk. We interpret this as evidence that targeted firms are credit-constrained and underline the implied welfare differences between upfront financial aid and public guarantees.

Using a partly hand-collected database, I measure the impact of management changes on business performance depending on the family ties with the incumbent CEO. Management changes taking place within the family are associated with a 20% higher likelihood of default.
