(number of unemployed/labor force) x 100
Fractional reserve banking system (modern banking)
- assume no one holds cash - banks are fully loaned up ( no excess reserves) depositors have 100 in deposits, borrowers have 90 in currency money supply = 90 + 100 = 190
What does the Federal Reserve Consist of?
- board of governors - 12 regional Fed banks - federal open market committee (FOMC)
Worker turnover
- hiring & training new workers is costly - paying high wages gives workers more incentive to stay, reduces turnover
Worker Effort
- monitor the efforts of their workers, "shrinkers" are fired
Worker Quality
- offering higher wages attracts better job applicants, increases quality of the firm's workforce
What are the assumptions for the Market of Loanable Funds (4)
- only one financial market - all savers deposit their saving in this market - all borrowers take out loans from this market - there is one interest rate, which is both the return to saving and the cost of borrowing
What happens when unions raise the minimum wage above equilibrium:
- quantity of labor demanded falls and unemployment results
What are the benefits of unemployment insurance?
- reduces uncertainty over incomes - gives the unemployed more time to search, resulting in better job matches and thus higher productivity
The Fed establishes fractional reserve requirements..
- the minimum amount of reserves that banks must hold against deposits - banks may hold more than this minimum if they choose
In our example, suppose bank assets appreciate by 5%, from $1000 to $1050:
- this increases bank capital!! from 50 to 100, doubling owners equity

Budget Deficit
A budget deficit reduces national saving the the supply of loanable funds --> it increases the equilibrium interest rate and decreases the equilibrium quantity
What is a government budget deficit? How does it affect interest rates, investment, and economic growth?
A government budget deficit arises when the government spends more than it receives in tax revenue. Because a government budget deficit reduces national saving, it raises interest rates, reduces private investment, and thus reduces economic growth
Bank A has a leverage ratio of 10, while Bank B has a leverage ratio of 20. Similar losses on bank loans at the two banks cause the value of their assets to fall by 7%. Which banks shows a larger change in bank capital? Does either bank remain solvent? Explain.
Bank B will show a larger change in bank capital. The decrease in assets will render Bank B insolvent because its assets will fall below its liabilities, a decrease in bank capital of 140%. Bank A will suffer a large decline in bank capital (70%) but will remain solvent.

Explain whether each of the following events increases, decreases, or has no effect on the unemployment rate and the labor-force participation rate: after a long search, Jon finds a job
When Jon finds a job after a long search, the unemployment rate decreases and there is no effect on the labor-force participation rate because Jon was and continues to be part of the labor force and the adult population
Explain whether each of the following events increases, decreases, or has no effect on the unemployment rate and the labor-force participation rate: Tyrion, a full-time college student, graduates and is immediately employed
When Tyrion graduates and is immediately employed, the unemployment rate decreases because the labor force increases, and the labor-force participation rate increases because Tyrion was part of the adult population is now part of the labor force

While cleaning your apartment, you look under the sofa cushion and find a $50 bill. you deposit the bill in your checking account. The Fed's reserve requirement is 20% of deposits. A. What is the max amount that the money supply could increase? B. What is the minimum amount that the money supply could increase?
a: 1/R = 1/.2 = 5 max possible increase in deposits: 5 x 50 = 250 **just money supply but also, money supply includes currency, which fall by 50!! SO max increased in money supply= 250-50 = 200 B: 0 if your ban k makes no loans from your deposit, currency falls by $50, deposits increase by $50, money supply does not change
In June 2009, at the trough of the Great Recession, the Bureau of Labor Statistics announced that of all adult Americans, 140,196,000 were employed, 14,729,000 were unemployed, and 80,729,000 were not in the labor force. Use this information to calculate: a:) the adult pop b:) the labor force c:) the labor-force participation rate d:) the unemployment rate
a:) adult pop = # of employed + # of unemployed # those not in the labor force = 140,196,000 + 14,729,000 + 80,729,000 = 235,654,000 b:) labor force = # of employed + number of unemployed 140,196,000 + 14,729,000 = 154,925,000 c:) the labor-force participation rate = labor force/adult population 154,925,000/235,654,000 = 65.7% d:) unemployment rate= # of unemployed/labor force 14,729,000/154,925,000 = 9.5%

Is being fired a good deterrent?
depends on how hard it is to find another job - if market wage is above equilibrium wage, there aren't enough jobs to go around, so workers have more incentive to work not shrink.
Bank's liabilities include:
deposits
M2

According to the theory of efficiency wages,
firms may find it profitable to pay above equilibrium wages
Fractional =
fragile !!
Unemployment insurance increases...
frictional unemployment - because people respond to incentives - UI benefits end when a workers takes a job, so workers have less incentive to search or take jobs while eligible to receive benefits
Persistent deficits lead to...
government debt
What does knowing the duration of unemployment do?
helps policy makers design better policies to help unemployed
100% reserve banking system
holds 100% of deposit as reserves: money supply = 0 + 100 = 100 ***** banks do not affect the size of money supply, double entry bookkeeping
Economists use labor-market data to evaluate how well an economy is using its most valuable resource---- its people. Two closely watched statistics are the unemployment rate and the employment-population ration (calculated as the percentage of the adult population that is employed). Explain what happens to each of these in the following scenarios: A stock market boom induces newly enriched 60-year old workers to take early retirement
if a stock market boom induces earlier retirement, the unemployment rate will rise and the employment-population ratio will fall

Two closely watched statistics are the unemployment rate and the employment-population ration (calculated as the percentage of the adult population that is employed). Explain what happens to each of these in the following scenarios: Numerous students graduate form college and immediately begin new jobs
if numerous students graduate and immediately find new jobs, the unemployment rate will fall and the employment-population ratio will rise
The economy of Elmendyn contains 2,000 $1 bills. if people hold all money as demand deposits and banks maintain 100% reserves, what is the quantity of money?
if people hold all money as demand deposits at banks with 100% reserves, the quantity of money is $2,000
The economy of Elmendyn contains 2,000 $1 bills. If people hold equal amounts of currency and demand deposits and banks maintain a reserve ratio of 10%, what is the quantity of money?
if people hold equal amounts of currency and demand deposits and the money multiplier for reserves is 10, then two equations must be satisfied (1) C = D, so that people have equal amounts of currency and demand deposits; and (2) 10 × ($2,000 - C) = D, so that the money multiplier (10) times the number of dollar bills that are not being held by people ($2,000 - C) equals the amount of demand deposits (D). Using the first equation in the second gives 10 × ($2,000 - D) = D, or $20,000 - 10D = D, or $20,000 = 11 D, so D = $1,818.18. Then C = $1,818.18. The quantity of money is C + D = $3,636.36
Economists use labor-market data to evaluate how well an economy is using its most valuable resource---- its people. Two closely watched statistics are the unemployment rate and the employment-population ration (calculated as the percentage of the adult population that is employed). Explain what happens to each of these in the following scenarios: After an unsuccessful search, some of the laid-off workers quit looking for new jobs
if some of the unemployed workers give up looking for a job, the unemployment rate will fall and the employment-population ratio will remain the same
Economists use labor-market data to evaluate how well an economy is using its most valuable resource---- its people. Two closely watched statistics are the unemployment rate and the employment-population ration (calculated as the percentage of the adult population that is employed). Explain what happens to each of these in the following scenarios: Numerous students graduate form college but cannot find work
if students graduate and cannot find work the unemployment rate will rise and the employment population ratio will remain unchanged

is unchanged, increases
Assets include:
laonds and reserves
The money supply includes all of the following EXCEPT
lines of credit accessible with credit cards
Minimum Wage Laws
minimum wage may exceed the equilibrium wage for the least skilled or experienced workers, causing structural unemployment -----> but this is a very small part of the labor force, so the minimum wage laws cannot explain most unemployment
Money Multiplier example, R = 10%

most spells of unemployment are short. yet most observed employment is long term - the small group of long-term unemployed persons has fairly little turnover, so it accounts for most of the unemployment observed over time
The supply of loanable funds comes from:
national saving - households with extra income loan it out to earn interest - public saving, if positive, adds to national saving and the supply of loanable funds - if negative, it reduces national saving and the supply of loanable funds

If a popular TV show on personal finance convinces Americans to save more for retirement, the _____________ curve for loanable funds would shift, driving the equilibrium interest rate _____________
supply, down
You take $100 you had kept under your mattress and deposit it in your bank account. If this $100 stays in the banking system as reserves and if banks hold reserves equal to 10% of deposits, by how much does the total amount of deposits in the banking system increase? By how much does the money supply increase?
take $100 that you held as currency and put it into the banking system, then the total amount of deposits in the banking system increases by $1,000, because a reserve ratio of 10% means the money multiplier is 1/0.10 = 10. Thus, the money supply increases by $900, because deposits increase by $1,000 but currency declines by $100.
Commodity Money
takes the form of commodity with intrinsic value ex:) gold coins, cigarettes in POW camps

"Outsiders"
workers who lose their jobs, are worse off - some outsiders go to non-unionized labor markets, which increases labor supply and reduces wage in those markets
"Insiders"
workers who remain employed, are better off
