Magazine: Current Issue
When hearing the terms “game theory” and “gamification” for the first time, they may sound almost synonymous. Interestingly, though, the word “game” has a very different meaning for each of these terms. The “game” in game theory is any interaction where one can “cleverly” choose their action (usually to optimize their outcome). The “game” in gamification is a fun pastime activity, from which one can borrow elements and themes that help engage users. Despite the separate evolution of each of these fields, and the different meaning of the term “game” in each of them, a central theme in both of these fields is incentivizing, or motivating, users to act in certain ways. The articles that comprise this issue of XRDS aim to introduce you, our reader, to a diverse but representative sample of scenarios from the worlds of algorithmic game theory and gamification, where a program or algorithm aims to incentivize or motivate some users to act in a certain manner. In a world where many computing systems interact with anonymous users from across the globe, such concerns have become more central than ever before.

SECTION: Features: Incentivizing Truthfulness
Algorithms versus mechanisms
Online markets and platforms rely on human user decisions as inputs. This generates the challenge of managing user incentives and misbehaviors as strategic entities. Surprisingly, one can show that designers do not require much additional computational power to overcome this challenge.

Do humans play equilibrium?
Online auctions and other computational strategic systems where human users interact are usually analyzed based on the assumptions that the users are rational and reach an equilibrium. This article shows that these modeling assumptions lead to significant errors, and that using behaviorally appropriate assumptions is important for achieving credible predictions in such systems.

Differential privacy as a tool for truthfulness in games
Differential privacy guarantees the input data from a single individual has a very small impact on the output of a computation. Tools from privacy can also be used in game theory and economics to incentivize people to truthfully reveal their data.

Incentivizing exploration via information asymmetry
As self-interested individuals make decisions over time, they utilize information revealed by others in the past and produce information that may help others in the future. So how can we incentivize exploration for the sake of the common good?

The ethics of gamification
Gamification is manipulation; at least that is what many people think. Because gamification is a powerful tool for modifying behaviors, how we should consider ethics specifically for gamification?
