A key question is why many multinational firms forgo foreign exchange derivative (FX) hedging and instead use operational hedging. We propose an explanation based on illiquidity and the unique advantages of operational hedges. We use 10-K filings to construct dynamically updated text-based measures of the offshore sale of output, purchase of input, and ownership of assets. We find that firms use FX derivatives when they are liquid and generally available. Otherwise, they often favor purchasing input from the same nations they sell output to, an operational hedge. Quasi-natural experiments based on new derivative product launches suggest a likely causal relation.

Using word content analysis on the time-series of IPO prospectuses, we show that issuers tradeoff underpricing and strategic disclosure as potential hedges against litigation risk. This tradeoff explains a significant fraction of the variation in prospectus revision patterns, IPO underpricing, the partial adjustment phenomenon, and litigation outcomes. We find that strong disclosure is an effective hedge against all types of lawsuits. Underpricing, however, is an effective hedge only against Section 11 lawsuits, those lawsuits which are most damaging to the underwriter. Underwriters who fail to adequately hedge litigation risk experience economically large penalties, including loss of market share.

We examine the impact of lost intellectual property protection on innovation, competition, firm performance, and valuation. We consider firms whose ability to protect intellectual property (IP) using patents is weakened following a major Supreme Court decision. We use large language models (LLM) to identify firms’ patent portfolios’ exposure to this decision and find an unequal impact. Large firms gain and small firms lose. Large impacted firms benefit as their sales growth increases and their exposure to lawsuits decreases. Small impacted firms lose as they face increased competition, product-market encroachment, and lower profits and valuations. They increase R&D and nondisclosure agreements.
