What is the New Economy, what makes it new, and what are the implications for antitrust, regulation and macroeconomic policy? Providing a non-technical and compelling analysis of the modern macro-economy, the contributors to this volume, eminent scholars all, provide their views on the New...

We model an environment where e-retailers sell similar products and endogenously engage in both brand advertising (to create loyal customers) and price advertising (to attract "shoppers"). In contrast to models where loyalty is exogenous, endogenizing the creation of loyal customers by allowing...

This paper examines four million daily price observations for more than 1,000 consumer electronics products on the price comparison site <externallink id="http://Shopper.com" type="url">http://Shopper.com</externallink>. We find little support for the notion that prices on the Internet are converging to the 'law of one price.' In addition, observed levels of...

We examine the equilibrium interaction between a market for price information (controlled by a gatekeeper) and the homogenous product market it serves. The gatekeeper charges fees to firms that advertise prices on its Internet site and to consumers who access the list of advertised prices....

"We exploit a unique dataset from a price comparison site to estimate the determinants of clicks received by online retailers. We find that a firm enjoys a 60% jump in its clicks when it offers the lowest price at the site, and failure to account for discontinuities distorts parameter estimates...

We study the impact of the Euro on prices charged by online retailers within the European Union. Our data span the period before and after the Euro was introduced, cover a variety of products, and include countries inside and outside of the Eurozone. After controlling for cost, demand, and...

Price dispersion is ubiquitous in settings that closely approximate textbook Bertrand competition. We show that only a little bounded rationality among sellers is needed to rationalize such dispersion. A variety of statistical tests, based on datasets from two independent laboratory experiments...

We analyze an oligopoly model of homogeneous product price competition that allows for discontinuities in demand and/or costs. Conditions under which only zero profit equilibrium outcomes obtain in such settings are provided. We then illustrate through a series of examples that the conditions...
