A business student conjectures that the Internet caused companies to become more profitable, since many transactions previously

handled “face-to-face” could now be completed online. The student compares earnings from a sample of companies from the 1980s to a sample from the 2000s. Explain why this is an observational study. If indeed profitability increased, can she conclude the Internet was the cause? Why or why not?

Answer: This is an observational study. The reason being that in an observational study , the subject in the study are put into treatment groups or control groups either by their own action or by someone else who is not involved in the research study but in a controlled experiment, researcher take control by randomly assigning subjects to control or treatment group.

Whereas,

Experimental studies are ones where researchers introduce an intervention and study the effects. Experimental studies are usually randomized, meaning the subjects are grouped by chance.

If indeed profitability increased, she cannot conclude the Internet was the cause, this is  due to the redundancies i.e.  the results of observational studies are, by their nature, open to dispute. They run the risk of containing confounding biases.

Suppose that the U.S. government decides to charge wine consumers a tax. Before the tax, 30 billion bottles of wine were sold ev
zmey [24]

Answer:

The amount of the tax on a bottle of wine is $5 per bottle. Of this amount, the burden that falls on consumers is $3 per bottle, and the burden that falls on producers is $2 per bottle. True or False: The effect of the tax on the quantity sold would have been larger if the tax had been levied on producers.

Explanation:

The amount of the tax on a bottle of wine is $5 ($3 + $2).

The burden on consumers is $3 ($9 - $6), which is the difference between the after-tax purchase price and the before-tax purchase price for consumers.  This implies that the burden passed to consumers is $3 out of the total tax burden of $5.

The burden on producers is $2 ($6 - $4) which represents the difference between before-tax selling price and the after-tax selling price for the producers.  This means that the burden passed to producers is $2 out of the total tax burden of $5.

If the tax burden were passed to the producers alone, the selling price would have been more than $11 ($6 + 5).  This would have reduced demand for wine as consumers would have been forced to bear the total burden.  This would have made the tax unequitable.  This would have been the case unless demand is inelastic.  That means that the total demanded is not sensitive to price increases.
