| Abstract: | This paper analyzes how patent protection affects economic growth in a continuous-time overlapping generations model with lab-equipment type R&D-based growth. We show that increasing patent breadth may generate an inverted-U effect of patents on economic growth, an effect which is partly consistent with an empirically observed nonmonotonic relationship between patent protection and economic growth. This paper also shows that the combinations of heterogeneous households with finite lifetimes and the lab-equipment type R&D specification are relevant for deriving the inverted-U effect of patent protection on economic growth. |

| Abstract: | This paper documents the extent of copying and estimates the returns to originality in online news production. We build a unique dataset combining all the online content produced by French news media during the year 2013 with new micro audience data. We develop a topic detection algorithm that identifies each news event, trace the timeline of each story, and study news propagation. We unravel new evidence on online news production. First, we document high reactivity of online media: one quarter of the news stories are reproduced online in under 4 minutes. Second, we show that this comes with extensive copying: only 33% of the online content is original. Third, we investigate the cost of copying for original news producers. Using article-level variations and media-level daily audience combined with article-level social media statistics, we find that readers partly switch to the original producers, thereby mitigating the newsgathering incentive problem raised by copying. |
