The cross-sectional dispersion of firm-level investment rates is procyclical. This makes investment rates different from productivity, output, and employment growth, which have countercyclical dispersions. A calibrated heterogeneous-firm business cycle model with nonconvex capital adjustment...

This paper studies the innovation dynamics of an oligopolistic industry. The firms compete not only in the output market but also by engaging in productivity enhancing innovations to reduce labor costs. Rent sharing may generate productivity dependent wage differentials. Productivity growth...

In this paper we investigate the trade-off faced by regulators who must set a price for an intermediate good somewhere between the marginal cost and the monopoly price. We utilize a growth model with monopolistic suppliers of intermediate goods. Investment in innovation is required to produce a...

We consider the optimal market segmentation problem of a monopolist that faces a continuum of customers when it is costly to prevent resale (or parallel trade) among groups. In our framework, the monopolist chooses the number k≥1 of market segments, but also their design and the discriminatory...

Early 2012 the Organization for Economic Cooperation and Development (OECD) released a Review on Telecommunications Policy and Regulation in Mexico, which was heavily criticized by consultants of Mexico’s incumbent telephone companies. The OECD answered the objections only formally, arguing...

Yardstick competition is an incentive regulatory tool which allows the regulator to introduce virtual competition into monopolistic industries. But as with any competitive environnement, regulated firms may have incentives to collude, thereby undermining the efficiency of the regulation. We...

This paper shows how a stationary tax policy can optimally address a flow externality associated with resource extraction when the policymaker faces asymmetric information. In the model I consider, the policymaker must set policy in each period before the realization of a price shock. Resource...

The paper explores the role of R&D investments reducing fixed production costs in entry deterrence. An incumbent monopolist and a potential entrant can perform R&D to reduce their fixed production costs, with bidirectional and asymmetric technological spillovers. It is shown that deterrence,...

Arrow (1962) argued that since a monopoly restricts output relative to a competitive industry, it would be less willing to pay a fixed cost to adopt a new technology. We develop a new theory of why a monopolistic industry innovates less. Firms often face major problems in integrating new...

This paper studies a monopoly pricing problem when the seller can choose the timing of a trade with each buyer, and a buyer's valuation of the seller's good is the weighted sum of his and other buyers' private signals. We show that it is optimal for the seller to employ a sequential scheme that...
