I show that households work and earn more (less) when their floating‐rate mortgage payments quasi‐exogenously increase (decrease). The response is sizable and asymmetric: on average, households adjust their income by 35% of the change in their mortgage payment, but the response is significantly stronger following an increase in payments. While men in dual‐earner, childless households respond the most on average, the asymmetry is most pronounced for women and young workers, who respond particularly strongly to payment increases. The asymmetry of the labor supply elasticity may help explain the wide range of elasticities found in previous research.

Using cross-country and German administrative data on robotization, we show that the impact of robots on firms and labor markets is limited. First, investment in robots is small and highly concentrated in a few industries, representing less than 0.3% of aggregate expenditures on equipment. Second, robotization does not grow as rapidly as Information Technology did in the past, and current growth is driven by gains in developing countries. Third, firms invest in robots when they face difficulties in finding workers and subsequently increase employment after the investment. The total employment effect in exposed industries and regions is negative but modest in magnitude. We discuss why the effects of robots are limited and demonstrate that other digital technologies have more potential for large economic impact.

Poison pills are among the most powerful antitakeover provisions, but studying their economic impact is challenging because of the obvious endogeneity concerns. We address the problem by studying U.S. states’ staggered adoption of poison pill laws (PPLs), which strengthen the right to adopt a pill (i.e., the shadow pill ) and increase the validity of visible pills. We document that PPLs make visible pill policy aligned with economic incentives, increasing pill adoption among firms with a high likelihood of takeover, but decreasing it among firms with low takeover likelihood. We also document that PPLs positively impact firm value, especially for innovative firms with more intangible assets.
