In linear-city models, if firms are allowed (not allowed) to locate outside the linear city, they engage in excessive (insufficient) R&D investments from the normative viewpoint. This implies that the feasible set of locations drastically affects their investments.

We perform comparative statics for a general model of asymmetric oligopoly and derive a concise formula for the response of one firm to a marginal change in its rival’s strategic variable, taking into account the responses of all other firms. We obtain the conditions under which the sign of...

This paper analyzes the unilateral choices of application compatibility by platforms and the endogenous affiliations of two different groups (content providers and users). We find a novel result that for both platforms to unilaterally choose application compatibility is not an equilibrium unless...

We analyze the sourcing strategies of firms active in the Spanish manufacturing sector. We show that firms that select strategies of vertical integration and of foreign sourcing ex post tend to have been more productive, ex ante, than other firms.

Consider the Hotelling linear spatial duopoly with firm uncertainty over the consumer mean. As uncertainty about the mean grows relative to the dispersion of consumers, competitive locations become socially optimal. A limit result for discontinuous, log-concave densities is also established.

This note studies exchange rate pass-through to the prices of domestically produced goods, exploring the firm-level pricing survey conducted by the Bank of Korea. The data reveal the imported inputs channel of, as well as nonlinear and asymmetric, exchange rate-pass-through.

When bidders have different risk aversion levels, we determine in a first-price auction, the asymmetric equilibrium strategies. We analyze the impact of asymmetric risk aversion levels on bidders’ markups and on the expected revenue and allocative efficiency of the auction.

We find strong evidence that US common stocks have been a hedge against inflation in the long run, from the early 1950s. Adopting a two-regime threshold vector error-correction model, we find that the stock price and the goods price are co-integrated with unit elasticity, with stock return and...

We develop a model of product differentiation in which firms strategically compete in product quality and advertising intensity. Products exhibit a combination of vertical and horizontal differentiation. A consumer’s utility has a stochastic relationship with quality, but they are more likely...
