Game Theory, Behavioral Finance, and Investing: Part 1 of 5 | Portfolio Investing Blog: Portfolioist Watching the market this year has been like observing an exercise in game theory and behavioral finance, and the two fields are closely related. Game theory is the study of how a rational person makes decisions in uncertain situations. As the name suggests, game theory was developed with the intent of developing optimal strategies in games in which chance or the decisions of an opponent play a role in your outcome. There is a huge literature of both game theory applied to financial decisions and behavioral finance. Notice that in my description of game theory, I write that people act to maximize their satisfaction rather than their returns or their wealth. The games on Wall Street come in a variety of forms. In this five-part series of posts, I will explore a number of the challenges that investors face from the perspective of game theory and behavioral finance.

Teachers Love SMART Boards: Mathematics I was searching through my past blog posts and I'm quite surprised that I have not written a post about the amazing flash-based resources found on Crickweb. This site contains hundreds of quality interactive resources for children aged 4 to 11. For my U.S. readers, the activities are organized into three age groups: The Early Years (age 4 to 5), Key Stage 1 (age 6 to 7), and Key Stage 2 (age 8 to 11). The basic subject areas include Math, Science, History, and Literacy. Spanish, and even Design & Technology. The resources contained on this site are all interactive and very few of them require keyboard input. of the activities only require students to touch or drag objects. I've included a few screen shots but the best way to find what your looking for is to browse around and play with the activities. Sharing is Caring!

The Costs of “Good” Economics If there is a central argument to 13 Bankers, it is that politics matters. The financial crisis was the result of a long-term transformation of the financial sector and its place in the overall economy, and that transformation occurred because of—and contributed to—a shift in the political balance of power. Daron Acemoglu and James Robinson, authors of Why Nations Fail, take up this theme on a much broader scale in their recent article in the Journal of Economic Perspectives, “Economics Versus Politics: Pitfalls of Policy Advice,” burnishing their reputations as two of the most subversive thinkers around. People have always known that economics and politics are related: that economic power produces political power and that political institutions constrain economic policy choices. This is what Acemoglu and Robinson contest. One specific consequence of weaker unions is that “income will typically be redistributed from workers to the managers and owners of firms.” This all seems obvious.

Powerful Images to Give Lessons Punch One of the benefits of having an Interactive Whiteboard in the classroom (or even just a data projector) is the opportunity to display full colour high quality images instead of grainy acetates or posters. With a powerful image you can really add some “punch” to your lesson. Put images up while students are coming into the room – use them as part of a lesson starter – stimulate questions. What is going on here? Why is the astronaut wearing that suit? Why is it white? The Big Picture One of my favourite sites for these kind of inspirational images is The Big Picture from the Boston Times. Here is just a selection of the great images that you could use in different curriculum areas: For Science; Mercury Images, Robots, Hubble Images, International Space Station, Earth and Environment, Animals, Zoos, Swine Flu. For Citizenship powerful images of the protests in Iran, and here. For Geography – images of Cyclones, Earth Observed, Hurricanes from Above, Hurricane Ike Flickr E2BN Gallery
