Patent-Based News Shocks
We exploit firm-level data on patent grants and subsequent reactions of stocks to identify technological news shocks. Changes in stock market valuations due to announcements of individual patent grants represent expected future increases in the technology level, which we refer to as patent-based news shocks. Our patentbased news shocks resemble diffusion news, in that they do not affect total factor productivity in the short run but induce a strong permanent effect after five years. These shocks produce positive comovement between consumption, output, investment, and hours. Unlike the ...

Monetary policy expectations and economic fluctuations at the zero lower bound
We propose a recursive VAR model augmented with survey-based measures of future interest rates to identify the effects of forward guidance on the U.S. economy. Our results show that when interest rates are away from the zero lower bound (ZLB), an exogenous shift in the perception toward higher future interest rates leads to an increase in current economic activity. However, when policy rates fall to the ZLB, economic activity decreases following an upward revision to expected future interest rates. These findings are robust to alternative estimation frameworks, identification schemes and data ...

What Drives Inventory Accumulation? News on Rates of Return and Marginal Costs
We study the effects of news shocks on inventory accumulation in a structural VAR framework. We establish that inventories react strongly and positively to news about future increases in total factor productivity. Theory suggests that the transmission channel of news shocks to inventories works through movements in marginal costs, through movements in sales, or through interest rates. We provide evidence that changes in external and internal rates of return are central to the transmission for such news shocks. We do not find evidence of a strong substitution effect that shifts production from ...

Good News, Leverage, and Sudden Stops
One of the major debates in open economy macroeconomics is the extent to which capital inflows are beneficial for growth. In principle, these flows allow countries to increase their consumption and investment spending beyond their income by enabling them to tap into foreign saving. Periods of such borrowing, however, are associated with large trade deficits, external debt accumulation, and, in some cases, overheating when these economies operate beyond their potential output level for an extended period of time. The relevant question in this context is whether the rate at which a country is ...
