Friends in Media

We test the independence of news content from financial journalists’ social networks. We find that corporate events reported by connected journalists—such as those sharing a working relationship or common schooling institutions with the respective company management—are associated with markedly more favorable coverage. Positive media slant in these articles significantly increases stock market responses and distorts longer-term capital allocation, suggesting real effects of journalist connections in the financial markets.

The Real Effects of Trend-seeking and Extrapolation: Evidence from M&As
with Eliezer Fich

Industry-peers’ earnings surprises announced just hours before the M&A announcements correlate with the acquirers’ M&A announcement return. Consistent with behavioral biases, a week after the M&A announcement, acquirers’ response to the earnings surprises disappears. While the acquirers’ stock misvaluation is transitory, other effects are not. We show that larger earnings surprises are related to increased bid competition, to higher premium revisions, and to more withdrawn M&As. These results indicate that trend-seeking and extrapolation could create material distortions in some M&A transactions.

Firms’ Internal Networks and Austerity Spillover
with Antonio De Vito and Martin Jacob
Media coverage: LSE Business Review 

We study how fiscal consolidation (austerity) shocks transmit across countries through multinationals’ internal networks of subsidiaries. Using a large multicountry subsidiary-level data set, we find that local business units cut capital investment in response to a foreign austerity shock. Two channels contribute to the propagation of these shocks: production linkages among subsidiaries and financial constraints. In the aggregate, domestic investment and employment decline with higher exposure to fiscal shocks originated abroad, suggesting that such spillover matters for overall economic activity.

Foreign Bribery and Takeovers: International Evidence

Using exogenous implementations of anti-bribery laws cross 41 countries, I find that criminalizing acquirers for foreign bribery reduces aggregate cross-border M&A activities by approximately 30%, acquirers’ gains by over half, and bid premium by 10%. These effects are stronger for public transactions and for targets located in countries (industries) with a higher level of corruption. The findings support the efficient side-payment model, which predicts a positive relation between bribery and cross-border transaction value. 

Investment under Uncertainty: Do Firm Boundaries Matter?
with Jingyuan Mo

We examine how firms’ vertical structure affects investment under output price uncertainty. Exploiting a unique industrial organization in the oil exploration and production industry, where certain producers vertically integrate into downstream segments, we find that these integrated producers cut investments significantly more than do standalone producers under exogenous oil price uncertainty shocks. This finding is consistent with a real option model of investment, where a higher level of capital irreversibility amplifies the uncertainty effects on actual investment.
