Empirical studies on information communication technologies (ICT) typically aggregate the "information" and "communication" components together. We show theoretically and empirically that these have very different effects on the empowerment of employees, and by extension on wage inequality. If...

Why do firms decide to offshore certain parts of their production process? What qualifies certain countries as particularly attractive locations to offshore? In this paper we address these questions with a theory of international production hierarchies in which organizations arise endogenously...

A survey of art history textbooks identifies and ranks the eight most important works of the 20th century. The most important painting of the century was Les Demoiselles d'Avignon, executed by Picasso at the age of 26, which began the development of Cubism. Among the other seven works, a...

Persuasive communication functions not only through content but also delivery, e.g., facial expression, tone of voice, and diction. This paper examines the persuasiveness of delivery in start-up pitches. Using machine learning (ML) algorithms to process full pitch videos, we quantify persuasion...

How does lie detection constrain the potential for one person to persuade another to change her action? We consider a model of Bayesian persuasion in which the Receiver can detect lies with positive probability. We show that the Sender lies more when the lie detection probability increases. As...

How do communication costs affect the production of new ideas and inventions? To answer this question, we study the introduction of the Uniform Penny Post in Great Britain in 1840. This reform replaced the previous system of expensive distance-based postage fees with a uniform low rate of one...

The role of data analysis in communication, persuasion, and decision-making is discussed. Some problems with current data-analysis practice are presented, including communication, complex models, large data bases, one-pass processing, rigid assumptions, resistance, validity, prior information,...

Information is a crucial ingredient in economic decision making. Yet measuring the extent of information exchange among individuals and its effect on economic outcomes is a difficult task. We use the universe of de-identified cellphone usage records from more than one million users in a Chinese...

We investigate models of cheap talk, information disclosure, and Bayesian persuasion, in a unified experimental framework. Our umbrella design permits the analysis of models that share the same structure regarding preferences and information, but differ in two dimensions: the rules governing...

New surveys provide a wealth of information on how economic agents form their expectations and how those expectations shape their decisions. We review recent evidence on how changes in macroeconomic expectations, particularly inflation expectations, affect households' and firms' actions. We show...
