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...

We investigate the welfare effects of third-degree price discrimination by a two-sided platform that enables interaction between buyers and sellers. Sellers are heterogenous with respect to their per-interaction benefit, and, under price discrimination, the platform can condition its fee on...

The empirical study undertaken here employs a structural VAR to estimate the dynamic adjustment of manufacturing sales and inventories to both nominal demand and real supply shocks. The analysis suggests that these impulse responses are generally consistent with those of an equilibrium model of...

Using the approach suggested by Gabaix (Econometrica 2011) this paper demonstrates that idiosyncratic shocks in the largest firms are important for an understanding of aggregate volatility in German manufacturing industries. The implications of this finding for theoretical and empirical research...

We study how firms' expectations and actions are affected by both aggregate and industry-specific conditions using a survey of French manufacturing firms. We document an important new stylized fact. In response to industry-level shocks that have no aggregate effects, firms' aggregate...

We study how firms' expectations and actions are affected by both aggregate and industry-specific conditions using a survey of French manufacturing firms. We document two novel features. First, the adjustment of firms' expectations is more rapid after industry-specific shocks than aggregate...

This study establishes the first empirical evidence of the impact of economic uncertainty shocks on industry-level investment, output and employment in Australia. We find the Construction and Financial and Insurance Services industries are the most impacted by a shock to economic uncertainty....
