An important question in public economics is to what extent changes in government funding lead to changes in private donations. In this chapter we identify and summarize four theoretical perspectives answering this question: the micro-economic, institutional-political, institutional signaling, and organizational perspective.

International Game Theory Review, 2001
We introduce the notion of a "crowding game", where individuals choose to locate themselves among finitely many compartments, each with a capacity (size) and a cost (price). Individuals have a common notion of physical comfort (freedom from crowding), which is increasing in the size of their compartment, decreasing in the number (or mass) of other ...

AbstractWe present an example‐based crowd simulation technique. Most crowd simulation techniques assume that the behavior exhibited by each person in the crowd can be defined by a restricted set of rules. This assumption limits the behavioral complexity of the simulated agents. By learning from real‐world examples, our autonomous agents display complex

There are 2 elements that make ‘‘crowding’’ interesting— mechanism (causality) and manifestation (effect). In our companion paper, Larry Roberts addresses mechanisms. Here, we focus on manifestation. As ecologists, it is difficult to get too excited about Clark Read’s paper on the ‘‘crowding effect’’ in cestodes, at least initially.

Adjunct proceedings of the 25th annual ACM symposium on User interface software and technology, 2012
Automated systems are not yet able to engage in a robust dialogue with users due the complexity and ambiguity of natural language. However, humans can easily converse with one another and maintain a shared history of past interactions. In this paper, we introduce Chorus, a system that enables real-time, two-way natural language conversation between an ...

2009I am constantly intrigued by the way that some sort of collective web-based intelligence seems to cause specific issues to pop up in multiple places at the same time.

Geofencing mechanisms allow for timely message delivery to the visitors of predefined target areas. However, conventional geofencing approaches poorly support mobile data collection scenarios in which experts need in situ assistance. In this paper, we propose crowd geofencing environments, in which a large number of crowdworkers generate geofences to ...

Learning Crowd Motion Dynamics with Crowds
Proceedings of the ACM on Computer Graphics and Interactive TechniquesReinforcement Learning (RL) has become a popular framework for learning desired behaviors for computational agents in graphics and games. In a multi-agent crowd, one major goal is for agents to avoid collisions while navigating in a dynamic environment.

Crowdsourcing gives us a way to leverage the complementary strengths of humans and machines. But how do we solve the problem of low-quality crowdwork?
