This paper examines the informativeness of consumer information networks and their effect on price competition between firms. Under the proposed information mechanism, consumers share their initial information with the members of their network and as such become better informed. The main result...

We study optimal pricing in the presence of recommender systems. A recommender system affects the market in two ways: (i) it creates value by reducing product uncertainty for the customers and hence (ii) its recommendations can be offered as add-ons which generate informational externalities....

A firm’s choices can shape patterns of consumer communication about its product. This paper examines the problem for a firm that can both set price and target sales when selling a product of hidden, exogenous quality over two sales rounds to consumers who share information locally with their...

The Web is the largest human information construct in history transforming our society. How can we understand, measure and model the Web evolution in order to design effective policies and optimize its social benefit? Early measurements of the Internet traffic and the Web graph indicated the...

We study how forcing financially distressed consumer debtors to repay a larger fraction of debt can lead them to misreport data fraudulently. Using a plausibly exogenous policy change that required debtors to increase repayment to creditors, we document that debtors manipulated data to avoid...

I show that an introduction of a liability on firms, proportional to the difference between consumers' beliefs and the effective terms of purchase/contract, can improve both social welfare and consumer surplus, depending on the relative magnitudes of: 1) decrease in the gap between the beliefs...

Using data on marginal interest rates of loan and deposit products by Spanish banks, we find that the level of interest rates on loans (deposits) across geographic markets decrease (increase) with the number of banks in each market, and that the level of interest rates on loans increases with...

We examine how word-of-mouth learning may lead to uniform and possibly inefficient actions in finite time among a network of agents. In our model, agents are identically informed a priori and observe network neighbors’ actions as well as the payoffs of some or all of those actions (a...

Store liquidation is the time-constrained divestment of retail outlets through an in-store sale of inventory. The retail industry depends extensively on store liquidation, not only as a means for investors to recover capital from failed ventures, but also to allow managers of going concerns to...
