Assuming constant marginal cost, it is shown that a switch from specific to ad valorem taxation has no effect on the critical discount factor required to sustain collusion. This result is shown to hold for Cournot oligopoly as well as for Bertrand oligopoly when collusion is sustained with...

This paper studies a job market signaling model with imperfect competition among employers. In our basic model, workers are differentiated in productivity and preference over employers, both of which are workers' private information. We conclude that if competition is sufficiently strong, a...

I present a game-theoretic model where economic competition and attention competition are interdependent. On the one hand the effort to attract consumer attention depends on the value of attention to the firm which depends on the grade of price competition among all perceived firms. On the other...

I develop a model of dynamic firm entry, oligopolistic competition and returns to scale in order to decompose TFP fluctuations into technical change, economic profit and markup fluctuations. I show that economic profits cause short-run upward bias in measured TFP, but this subsides to upward...

We provide a methodology to study the role of market distortions on the emergence of indeterminacy and bifurcations. Most of the specific market imperfections considered in the related literature are particular cases of our framework. Comparing them we obtain several equivalence results in terms...

I analyze two opposing effects of firm dynamics on productivity over the business cycle. Consider net exit, on the one hand it reallocates resources to incumbents whose productivity improves through scale economies, on the other hand it reduces the competitive pressure incumbents face which...

This paper uses a model (consisting of a linear estimate of a demand curve, a linear quadratic cost curve and a logistic diffusion curve) and four types of imperfectly competitive behaviour — monopolistic intertemporal profit maximization, a dynamic Bertrand oligopoly, and a duopolistic...

Firms tend to compete more aggressively in financial distress; the intensified competition in turn reduces profit margins for everyone, pushing some further into distress. To study such feedback and contagion effects, we incorporate dynamic strategic competition into an industry equilibrium with...

This is the supplemental material to the paper titled "Feedback and Contagion through Distressed Competition." It includes additional empirical, theoretical, and quantitative results. It also includes illustration for the numerical algorithm for our model solution
