Spillover effects of entry and city development (Revise & Resubmit at the Journal of the European Economic Association)

Consumption amenities -such as restaurants and bars- are important drivers of urban development. This article focuses on the food and beverage service industry in the Netherlands, and investigates to what extent different amenity services generate spillovers on each other. Using a unique dataset on firms’ revenues and the number of market participants, I extend previous entry models and simultaneously estimate a static two-type entry model with revenue equations. The model controls for unobserved characteristics that can be erroneously interpreted as spillovers. It also allows for market expansion effects. I find that for the case of take-out places and bars, spillover effects upon entry are mainly unidirectional. Counterfactual analyses show that taking into account this asymmetry is relevant for both new entrant firms and urban planners. 

Click & Collect Entry Regulation in the Grocery Retail Sector (joint with Céline Bonnet, Zohra Bouamra-Mechemache, and Claire Chambolle)

Click-and-collect (C&C) services have rapidly expanded in the grocery retail sector and, in many countries, their adoption supersedes the use of delivery services. In France, the upsurge of C&C services in the grocery retail sector prompted concerns among policymakers, leading to the implementation of a new entry regulation in 2014. This article examines the consequences of this regulation on the openings of C&C warehouses in France. Through a difference-in-differences analysis, spanning from 2009 to 2017, we show a significant adverse impact of the legislation on the opening of C&C warehouses, particularly affecting the two leading retail chains in this format. Additionally, we observe a detrimental effect on the revenue growth of C&C services for both retail chains. Furthermore, our analysis show the varying effects of adjacent and independent C&C warehouse entries on local market concentration.

How Bundling Impacts Firms' Entry Decisions: Evidence from Broadband Internet (joint with Lukasz Grzybowski and Christine Zulehner) 

This article analyzes whether fixed-mobile bundling by the incumbent operator limits competition in the broadband industry. Using a unique dataset on the share of consumers subscribed to the incumbent’s quadruple-play services, we estimate a structural entry model that allows us  to measure heterogeneous effects on competition. In particular, we find that the incumbent’s bundling mainly affects the entry of small operators. Big competitors, also able to provide fixed-mobile bundles, do not seem to be affected by the incumbents’ bundling.
