We explore conditions under which a multiproduct firm can profitably turn itself into a platform by "hosting rivals", i.e. by inviting rivals to sell products or services on top of its core product. Hosting eliminates the additional shopping costs to consumers of buying a specialist rival's...

We study the quantitative potential of DSGE models with incomplete information. In contrast to existing literature, we offer predictions that are robust across all possible private information structures that agents may have. Our approach maps DSGE models with information-frictions into a parallel...

"Likert scales" are the most standard and widespread instrument in survey research when measuring public opinion on political and economic issues. In this simple approach, respondents are given the opportunity to voice their agreement or disagreement on a set of issues by placing their attitudes on...

We present a framework for understanding the effects of automation and other types of technological changes on labor demand, and use it to interpret changes in US employment over the recent past. At the center of our framework is the task content of production. Automation, which enables capital to...

This paper analyzes how patent-induced shocks to labor productivity propagate into worker compensation using a new linkage of US patent applications to US business and worker tax records. We infer the causal effects of patent allowances by comparing firms whose patent applications were initially...

Discrete structures like graphs make it possible to naturally and exibly model complex phenomena. Since graphs that represent various types of information are increasingly available today, their analysis has become a popular subject of research. The graphs studied in the field of data science at...

Nous proposons un survol de travaux récents sur la concurrence entre vendeurs lorsqu'il y a sélection adverse et non-exclusivité, c'est-à-dire que l'acheteur peut simultané- ment échanger avec plusieurs vendeurs. Nous montrons que la sélection adverse favorise les tarifs convexes, qu'un tarif...

We introduce a novel approach addressing global analysis of a difficult class of nonconvexnonsmooth optimization problems within the important framework of Lagrangian-based methods. This genuine nonlinear class captures many problems in modern disparate fields of applications. It features complex...
