On the Welfare Effects and Political Economy of Competition‐Enhancing Policies
Open accessAbstract
We analyse the welfare effects of policies that intensify product market competition, and the channels through which they operate. Using a circular model of horizontal product differentiation with asymmetric costs, we study the effects of increased price competition on market selection among incumbent firms, cost reduction effort, and entry of new firms. The model also generates an endogenous demand for competition-enhancing or retarding policies arising from cost heterogeneity, and we demonstrate the possibility of a 'low-competition' political economy trap. Simulations of the model illustrate that the selection effects we analyse, which traditional cost-benefit analysis is unlikely to capture, can be large.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
