The main contribution of entrepreneurship theory to economics is to provide an account of market performance in disequilibrium but little empirical research has examined firm entry and exit in this context. We redress this by modelling the interrelationship between firm entry and exit in...

This paper conducts the first general equilibrium analysis of the role of entry, exit and profits in industry dynamics. The benefit of our model is twofold. First, to discriminate between entrants’ role of performing the entrepreneurial function of creating disequilibrium and the conventional...

What determines structure and profitability across markets for goods and services? Understanding the relationship between market structure and performance is critical for determining effective economic policy governing anti-trust, intellectual property, industry regulation, and international...

I address the degree to which variation in exposure to e-commerce is associated with entry and exit in the retail industry at the county level. To measure exposure to e-commmerce, I rely on within-state variation in relative search frequency for the phrase “amazon prime” as reported by...

We study the duopoly exit equilibrium in a multimarket environment with declining demand, and investigate the roles of strategic merger, agency cost, and collusion in a multimarket exit game.Cross-market spillovers with endogenous duration and the strategic merger of outside firms can serve as...

We analyze 69 entries and relocations by the Norwegian discount variety chain Europris during the period 2016 to 2019. We measure how its location choices affect local grocery stores’ performance, using a diff-in-diff strategy and data from a large Norwegian grocery chain. We combine detailed...

Worldwide, the overwhelming majority of large horizontal mergers are cleared by antitrust authorities unconditionally. The presumption seems to be that efficiencies from these mergers are sizeable. We calculate the compensating efficiencies that would prevent a merger from harming consumers for...

Weyl and Fabinger (2013) analyze the social incidence of competition and theoutput and welfare effects of third-degree price discrimination by considering thehypothetical entrance of exogenous quantity into a market. The formulas they use forthis purpose, however, are correct only for marginal...

A dual process model is proposed that identifies the conditions under which two separate and additive effects on brand preference may obtain. The first is an exposure-order effect that can influence attribute-based processing. The second is the effect of market entry-information that can result...
