Coral Gables, Fla. - May 25, 2011 - Economic recessions are weaker, expansions are stronger, and economic recovery is faster in U.S. states where people are more optimistic says a new study from the University of Miami School of Business Administration. Further, the effects are stronger in states where people are older, less educated and less socially connected.
"Previous studies have shown that economic conditions affect mood - people would expect this, it's more obvious," said Alok Kumar, the Gabelli Asset Management Professor of Finance at the University of Miami School of Business and one of the study's researchers. "Our study is unique in that it shows, for the first time, that mood and optimism can directly affect overall economic activity."
In order to determine the link between mood and economic conditions, Kumar, along with Vidhi Chhaochharia and George Korniotis, assistant professors of finance, used several factors to measure mood, optimism and pessimism not influenced by the economic environment. The factors are:
With these factors in mind, the researchers then studied how mood in a U.S. state affects local economic activity. To measure local economic performance, they created a novel index based on state housing conditions, the difference between state unemployment and national unemployment, and income growth. Here are the key findings:
These results are surprising because they imply that the economy is affected by non-economic, psychological factors. In an ideal world, mood, would not affect economic activity and retail sales because consumers would only spend more when their income was on the rise versus because the weather is pleasant.
"One policy implication of our study is that the development of sports-related infrastructures, like new sports stadiums or other factors that could effect the performance of local sports teams, is certainly something to consider as a way to make a real impact on a local economy for a relatively low cost," said Kumar.
