Answer:
Efficiency requires that one lighthouse is built since the willingness to pay of all the residents together is larger than the cost of providing the lighthouse
Explanation:
Since the lighthouse is a public good, according to the coase theorem, if the combined willingness to pay for the lighthouse of all of the people living on the islands is higher than the cost of the lighthouse, then a lighthouse should be built.
The total willingness to pay is:

The population willingness to pay is higher than the cost of building one lighthouse ($2000) but lower than the cost of building two lighthouses ($4000). Therefore, efficiency requires that one lighthouse is built since the willingness to pay of all the residents together is larger than the cost of providing the lighthouse.

Answer:
$11,700
Explanation:
The computation of the balance in the work in process at the end of the month is shown below:
= Direct material cost + direct labor cost + manufacturing overhead cost percentage of direct labor cost
= $1,800 + $3,300 + $3,300 × 200%
= $1,800 + $3,300 + $6,600
= $11,700
We simply added the direct material cost, direct labor cost and the manufacturing overhead cost so that the ending balance could arrive
According to the Keynesian approach an increase in the money supply increases real GDP by lowering interest rates which increases investment.
The Keynesian theory implied that during a recession inflationary pressures are low, but when the level of output is at or even pushing beyond potential gross domestic product, or GDP, the economy is at greater risk for inflation.
Keynesians do believe in an indirect link between the money supply and real GDP. They believe that expansionary monetary policy increases the supply of loanable funds available through the banking system, causing interest rates to fall.
