Abstract
This paper studies the incentives for and consequences of acquiring information about rivals in winner-take-all contests. Each player can acquire private information about the rival’s value from an arbitrarily large set of signals before the competition. A player who acquires a more accurate signal than their rival wins more often with the same expected effort as the rival. Being the target of a rival’s information acquisition does not harm the player, and learning partial information about each other benefits both players. Nevertheless, they may choose not to acquire any information if the accuracies of their signals are not publicly observable.

As a broad-based professional and international journal, the EER welcomes submissions of applied and theoretical research papers in all fields of economics. The aim of the EER is to contribute to the development of the science of economics and its applications, as well as to improve communication between academic researchers, teachers and policy makers across the European continent and beyond.
