Modern-day search platforms generally have two layers of information presentation. The outer layer displays the collection of search results with attributes selected by platforms, and consumers click on a product to reveal all its attributes in the inner layer. The information revealed in the...

Empirical evidence shows that the perception of information is strongly concentrated in those environments in which a mass of producers and users of knowledge interact through a distribution medium. This paper considers the consequences of this fact for economic equilibrium analysis. In...

Ranking algorithms are the information gatekeepers of the Internet era. We develop a stylized framework to study the effects of ranking algorithms on opinion dynamics. We consider rankings that depend on popularity and on personalization. We find that popularity driven rankings can enhance...

The paper addresses the issue of “fake news” through a well-known and widely studied experiment that illustrates possible uses of economics and game theory for understanding the phenomenon. Public news is viewed as an aggregation of decentralized pieces of valuable information about complex...

Despite substantial efforts to help consumers search in more intuitive ways, text search remains the predominant tool for product discovery online. In this paper, we explore the effects of visual and textual cues for search refinement on consumer search and purchasing behavior. We collaborate...

This paper examines information sharing between governments in an optimaltaxation framework. We present a taxonomy of alternative systems of international capital-income taxation and characterize the choice of tax rates and information exchange. The model reproduces the conclusion of the...

The issue of capital tax competition in source-based capital taxes is viewed to be unproblematic if residence-based capital taxation exists. The sustainability, however, of residence-based capital taxation depends on the co-operation of source countries to assist in collecting tax revenues that...

This paper examines information sharing between governments in an optimal taxation framework. We present a taxonomy of alternative systems of international capital income taxation and characterize the choice of tax rates and information exchange. The model reproduces the conclusion of the...

This study investigates how region-specific shocks affect international behavior of individuals when information is partially or scarcely spread across the border. We use both local and international tourist data pertaining to Hakone in Japan, to focus on two exogeneous region-specific shocks of...
