I derive a formula for the equilibrium distribution of markups in the search- theoretic model of imperfect competition of Butters (1977), Varian (1980), and Burdett and Judd (1983). The level of markups and the sign of the relationship between a seller's markup and its size depends on the extent...

Using data on 4.1 million apps at the Google Play Store from 2016 to 2019, we document that GDPR induced the exit of about a third of available apps; and in the quarters following implementation, entry of new apps fell by half. We estimate a structural model of demand and entry in the app...

Do large firms produce more valuable inventions, and if so, why? After confirming that large firms indeed produce more valuable inventions, we consider two possible sources: a superior ability to invent, or a superior ability to extract value from their inventions. We develop a simple model that...

We examine the role of spillover learning in shaping the value of exploratory versus incremental R&D. Using data from drug development, we show that novel drug candidates generate more knowledge spillovers than incremental ones. Despite being less likely to reach regulatory approval, they are...

This article adopts a marketing perspective to examine how blockchain technology can facilitate innovation by streamlining the licensing process of intellectual property (IP). It notes that in the traditional world, there can be a tension between inventors and developers when it comes to...

This paper studies how innovation reacts to foreign political risk and shapes its economic consequences. In a model with foreign political shocks that can disrupt the supply of foreign inputs, we show that greater political risk abroad increases domestic innovation, thereby lowering reliance on...

The extensive empirical macro- and micro-level evidence on the impact of job security provisions is largely inconclusive. We argue that the weak evidence is a consequence of the weak power of statistics used, which is suggested by a dynamic theory of plant-level labor demand that we develop....

This paper uses barcode-level price data for 16 advanced and emerging market countries over the period 2005-2022 to investigate the role of individual firms and product categories in aggregate inflation. We decompose inflation into the component due to macroeconomic shocks and the granular...

I study the equilibrium and the welfare effects of international trade when product markets are imperfectly competitive due of search frictions--as in Burdett and Judd (1983)--rather than product differentiation--as in Dixit and Stiglitz (1977). Markups are positive, even though there are...

Endogeneity is a primary concern when evaluating causal effects using observational panel data. While unit-specific intercepts control for unobserved time-invariant confounders, dependence between (i) regressors (e.g., marketing mix strategy of interests) and the current error term (regressor...
