" I see trees of green, red roses too"

http://news.yahoo.com/s/wisc/20070213/lo_wisc/10993944

This is local news about roses. Everybody buy roses for St. Valentines Day- this is an example of increase in demand in the period of time before this day that drives the prices up as well as the quantity demanded. I am not sure, but these changes in demand are caused by expectations for future.

What happened to supply and demand for roses this year is more than the natural increase in demand. Because of frosts in California this year roses crops decreased dramatically- just like after a hurricane in Connecticut this caused a decrease in supply of apples. Supply for roses was cut what caused an increase in price and a decrease quantity demanded.

In this situation, opposite to the ones that we talk about during class, those two changes happen in the same time. The roses market is much more complex than a graph with 2, 3 or 4 lines, but we can illustrate it using them what makes it easier to see why suddenly the price for roses doubles.

It happens because of a increase in demand and decrease in supply, which both contribute to this unusual jump of the prices.

More about the Super Bowl Ads

This is an article on Super Bowl Ads, that we discussed on the "main blog". I found more background to it in this article. The fact is that the bar is set higher and higher every year. Those commercials are the best of what producers can come up with. They are paying $2.6 mln for 30 sec of air time. This is the price for showing it to ablut 100mln viewers..
An interesting insight in this issue is that the ideas for three of those extremelly expensive ads came form the amateurs.
The article gives a link to all Super Bowl commercials. (HERE)
Its fun to see them againg.
