<p>Lafky: </p> <hr /> <div>[[Image:lafky1.jpg]]<br /> <br /> I am a second-year economics PhD student at the University of Pittsburgh. My research focuses on issues of reputation building and information sharing among agents. I have a long-term interest in building agent-based simulations of economic activity based on parameters gleaned from human subject experiments. My website is at http://www.pitt.edu/~jml44.<br /> <br /> '''1. What topics do you have some expertise in and would you be willing to help others learn them?'''<br /> <br /> Economics (bits and pieces at least), Auction Theory, Reputation <br /> building, Information sharing. <br /> <br /> '''2. What do you want to learn?'''<br /> <br /> Information flow across networks, information sharing from the <br /> perspective of other disciplines, network dynamics. <br /> <br /> '''3. Do you have any projects that would benefit from interdisciplinary <br /> approach?'''<br /> <br /> I have a project estimating optimal effort levels by firms in the<br /> presence of consumer information sharing. The environment is not <br /> analytically friendly, and I am interested to learn what techniques are<br /> employed in other fields to estimate optimal outcomes in complex <br /> systems. <br /> <br /> '''4. Do you have any ideas for what sort of project you would like to attack this summer?'''<br /> <br /> Point 3. above outlines one project. I would also like to build up<br /> a framework for simulations which can be easily modified based on <br /> observed human subject experimental behavior. <br /> <br /> '''5. What's your favorite &quot;big problem&quot;?'''<br /> <br /> Why do individuals contribute to large collective activities even<br /> when they personally have virtually no effect? Think of voting,<br /> resource conservation, or massive protests as examples. <br /> <br /> '''6. If you were given the opportunity to see where we were in one hundred years with respect to progress on one problem/subject, what would it be?'''<br /> <br /> Pure mathematics</div>
