Euro area companies with shareholder bases concentrated in their home country cut investment 20% more sharply after the COVID-19 shock than peers with more diversified owners, according to a study published by the European Central Bank. The research, combining ECB securities holdings data with firm financial statements, found that domestic equity ownership remains strongly concentrated, with limited cross-border diversification inside the monetary union.
Key facts
- Firms with home-biased shareholder bases reduced investment 20% more than more diversified peers after the pandemic shock, the ECB study found.
- The analysis covers euro area firms and uses security-level holdings data from the ECB's Securities Holdings Statistics alongside Compustat financial-statement data.
- The firms studied were in the sectors hardest hit by the pandemic, where exports fell by an average of 16%.
- The effect runs mainly through weaker equity resilience, with equity declining by 13%, while sales and bank financing stayed comparable.
- The study used a difference-in-differences design around the COVID-19 shock combined with propensity score matching.
How was the study carried out?
The authors built new firm-level measures of shareholder geographical concentration to test how home bias in equity holdings affects corporate investment resilience. They merged security-level holdings data from the ECB's Securities Holdings Statistics with firm-level financial statements from Compustat. They found that equity ownership remains heavily concentrated domestically, with only limited diversification across borders within the monetary union.
What did the pandemic shock reveal?
Using a difference-in-differences design around the COVID-19 shock, paired with propensity score matching, the researchers examined whether equity home bias shapes how firms respond to macroeconomic disruption. Among firms in the sectors most exposed to the pandemic, exports fell by an average of 16%. Within that group, companies whose shareholders were more concentrated at home cut investment by 20% more than their more diversified counterparts.
Why does the ownership structure matter?
The study attributes the gap mainly to weaker equity resilience: equity at the affected firms declined by 13%. Sales and bank financing, by contrast, remained comparable between the two groups, suggesting the investment shortfall was driven by the equity channel rather than by weaker demand or reduced lending.
What are the implications for the single market?
The findings point to the benefits of deeper cross-border equity integration for corporate resilience, the authors conclude. For a monetary union in which equity holdings remain largely national, the results suggest that firms reliant on domestic owners have less cushion when a common shock hits. The study adds firm-level evidence to the long-running debate over how far euro area capital markets remain fragmented along national lines.
What comes next?
The study does not set out a policy timetable, but its conclusions feed into the broader push for capital market integration across the euro area, where cross-border equity diversification remains limited.
