## The Real Effects of Hedge Fund Activism
- Analysis of productivity, asset allocation, and labor outcomes by Alon Brav, Wei Jiang, and Hyunseob Kim (2015).
- Investigates whether activists create real value or just transfer wealth.

## Core Research Question & Contribution
- Uses U.S. Census Bureau plant-level data to avoid 'Black Box' firm-level limitations.
- Disentangles efficiency gains from asset sales.
- Addresses survivorship bias by tracking plants after firm delisting.

## Data Sources and Sample
- Covers 1994–2007 activism events matched to Census/Survey of Manufacturers.
- Sample: 368 manufacturing events and 14,923 plant-year observations.
- Priority variable: Total Factor Productivity (TFP).

## Main Result: Productivity Dynamics
- TFP typically declines before an activist intervenes.
- TFP rebounds by +11.8% of a standard deviation within 3 years of intervention.

## Asset Allocation and Labor
- Target firms have a 23% plant sale rate vs. 13% for the control group.
- Sold plants show significant productivity gains under new ownership.
- Labor productivity rises (+9.2%) due to reduced hours (-4.3%), while wages remain stagnant (+1.1%).

## Identification and Bias
- Placebo tests show that matching plants without activists do not experience a V-shaped recovery.
- Switching from passive (13G) to active (13D) ownership triggers TFP gains.
- Study finds that previous reports underestimated gains because successful exits (firms going private) were excluded.
