Labor supply and demand scenarios

I need to select (6) scenarios, (I HAVE 5 already) that would cause a shift in labor supply and demand. The following areas have had high job growth rates and can be used for a scenario: transportation, insurance, and real estate industries. Please focus on the following questions: 1) What is the area of employment? 2) Why has the shift occurred? 3) In what direction would the shift in labor supply and demand go? 4) What would be its effect on the equilibrium of the labor market?

Do you think this is a good policy that is necessary to protect American workers or do you think that free trade is the answer and tariffs should be abolished?

On occasion, the US government steps in and issues a tariff on a particular product or raw material being imported into the US. This in turn causes the price of that product to rise. They do this in the attempt to protect various industries in the US. For instance, if the US Steel industry is hurting, a tariff on imported steel may be levied in order to raise the price of that imported steel so that the US steel companies can compete on price. Do you think this is a good policy that is necessary to protect American workers or do you think that free trade is the answer and tariffs should be abolished?

Simplified mathematical formula or model needed to demonstrate Tit for Tat pricing

If industries are engaging in a tit for tat strategy how would an observer/analyst "prove" it? Is there a model or mathematical formula (that's easy to follow?) I am comparing tit for tat pricing strategy between Ford and GM I have the success factors and Prisoner's Dilemma context setting. I only need a model or math formula that "proves" tit for tat pricing. Is there such a thing?
