Connecting to Power: Political Connections, Innovation, and Firm Dynamics
How do political connections affect firm dynamics, innovation, and creative destruction? To answer this question, we build a firm dynamics model, where we allow firms to invest in innovation and/or political connection to advance their productivity and to overcome certain market frictions. Our model generates a number of theoretical testable predictions and highlights a new interaction between static gains and dynamic losses from rent-seeking in aggregate productivity. We test the predictions of our model using a brand-new dataset on Italian firms and their workers. Our dataset spans the ...

Patents to Products: Product Innovation and Firm Dynamics
We study the relationship between patents and actual product innovation in the market, and how this relationship varies with firms’ market share. We use textual analysis to create a new data set that links patents to products of firms in the consumer goods sector. We find that patent filings are positively associated with subsequent product innovation by firms, but at least half of product innovation and growth comes from firms that never patent. We also find that market leaders use patents differently from followers. Market leaders have lower product innovation rates, though they rely on ...

Barriers to Creative Destruction: Large Firms and Nonproductive Strategies
This working paper reviews recent empirical evidence on large firms and nonproductivestrategies that hinder creative destruction and reallocation. The focus is on three types ofnonproductive strategies: political connections, nonproductive patenting, and anticompetitiveacquisitions. Across different contexts using granular micro data sets, we overwhelmingly see that asfirms gain market share, they increasingly rely on nonproductive strategies but reduce theirproductive, innovation-based strategies. I also discuss theoretical channels, aggregate implications,and potentials for some policies.

Creative Destruction and the Reallocation of Capital in Rural and Urban Areas
We test the implications of Schumpeter’s theory of creative destruction on food manufacturer births and deaths using a dynamic, unobserved effects count model with correlated random effects. We find evidence of a creative destruction process via the interaction of previous firm birth and death, which is correlated with higher rates of contemporaneous firm birth and death in a given location. Results support Marshall’s notion of “something is in the air,” as evidenced by the strong correlation between sources of unobserved heterogeneity in the birth and death processes. Consistent with ...
