|April 2020||Environmental Preferences and Technological Choices: Is Market Competition Clean or Dirty?|
with Philippe Aghion, Roland Bénabou, Ralf Martin: w26921
This paper investigates the joint effect of consumers' environmental concerns and product-market competition on firms' decisions whether to innovate “clean” or “dirty”. We first develop a step-by-step innovation model to capture the basic intuition that socially responsible consumers induce firms to escape competition by pursuing greener innovations. To test and quantify the theory, we bring together patent data, survey data on environmental values, and competition measures. Using a panel of 8,562 firms from the automobile sector that patented in 42 countries between 1998 and 2012, we indeed find that greater exposure to environmental attitudes has a significant positive effect on the probability for a firm to innovate in the clean direction, and all the more so the higher the degree of pr...

with Thomas Le Barbanchon, Roland Rathelot: w23406
Although the reservation wage plays a central role in job search models, empirical evidence on the determinants of reservation wages, including key policy variables such as unemployment insurance (UI), is scarce. In France, unemployed people must declare their reservation wage to the Public Employment Service when they register to claim UI benefits. We take advantage of these rich French administrative data and of a reform of UI rules to estimate the effect of the potential benefit duration (PBD) on reservation wages and on other dimensions of job selectivity, using a difference-in-difference strategy. We cannot reject that the elasticity of the reservation wage with respect to PBD is zero. Our results are precise and we can rule out elasticities larger than 0.006. Furthermore, we do not f...

|April 2015||Creative Destruction and Subjective Wellbeing|
with Philippe Aghion, Ufuk Akcigit, Angus Deaton: w21069
In this paper we analyze the relationship between turnover-driven growth and subjective wellbeing, using cross-sectional MSA level US data. We find that the effect of creative destruction on wellbeing is (i) unambiguously positive if we control for MSA-level unemployment, less so if we do not; (ii) more positive on future wellbeing than on current well-being; (iii) more positive in MSAs with faster growing industries or with industries that are less prone to outsourcing; (iv) more positive in MSAs within states with more generous unemployment insurance policies.
