By the end of this section, you will be able to:

  • Analyze whether monetary policy decisions should be made more democratically
  • Calculate the velocity of money
  • Evaluate the central bank’s influence on inflation, unemployment, asset bubbles, and leverage cycles
  • Calculate the effects of monetary stimulus

In the real world, effective monetary policy faces a number of significant hurdles. Monetary policy affects the economy only after a time lag that is typically long and of variable length. Remember, monetary policy involves a chain of events: the central bank    must perceive a situation in the economy, hold a meeting, and make a decision to react by tightening or loosening monetary policy. The change in monetary policy must percolate through the banking system, changing the quantity of loans and affecting interest rates. When interest rates change, businesses must change their investment levels and consumers must change their borrowing patterns when purchasing homes or cars. Then it takes time for these changes to filter through the rest of the economy.

As a result of this chain of events, monetary policy has little effect in the immediate future; instead, its primary effects are felt perhaps one to three years in the future. The reality of long and variable time lags does not mean that a central bank should refuse to make decisions. It does mean that central banks should be humble about taking action, because of the risk that their actions can create as much or more economic instability as they resolve.

Excess reserves

Banks are legally required to hold a minimum level of reserves, but no rule prohibits them from holding additional excess reserves    above the legally mandated limit. For example, during a recession banks may be hesitant to lend, because they fear that when the economy is contracting, a high proportion of loan applicants become less likely to repay their loans.

When many banks are choosing to hold excess reserves, expansionary monetary policy may not work well. This may occur because the banks are concerned about a deteriorating economy, while the central bank is trying to expand the money supply. If the banks prefer to hold excess reserves above the legally required level, the central bank cannot force individual banks to make loans. Similarly, sensible businesses and consumers may be reluctant to borrow substantial amounts of money in a recession    , because they recognize that firms’ sales and employees’ jobs are more insecure in a recession, and they do not want to face the need to make interest payments. The result is that during an especially deep recession, an expansionary monetary policy may have little effect on either the price level or the real GDP    .

Japan experienced this situation in the 1990s and early 2000s. Japan’s economy entered a period of very slow growth, dipping in and out of recession, in the early 1990s. By February 1999, the Bank of Japan had lowered the equivalent of its federal funds rate to 0%. It kept it there most of the time through 2003. Moreover, in the two years from March 2001 to March 2003, the Bank of Japan also expanded the money supply of the country by about 50%—an enormous increase. Even this highly expansionary monetary policy, however, had no substantial effect on stimulating aggregate demand. Japan’s economy continued to experience extremely slow growth into the mid-2000s.

what's marginal utility?
Abena Reply
the additional utility you get if you can consume one more unit of the good x
Luka
Thanks... then what's the law of diminishing marginal utility ?
Abena
The utility decreases with every unit you consume (most of the time). The first unit of consumption will therefore give you the highest utility. Sorry about my english
Luka
Okay... I understand now
Abena
Great!

Siddharth
Poverty of a country is also related to cultural, economical, and military domination. Usually, the dominant country imposes all of these powers when diplomatically needed or sometimes by force.
Ernest
You can also have considerable poverty in a rich country when such poverty is measured within sectors of its population. In other words, economic indicators can sometime mask such poverty.
Ernest
For example, the U.S.A. has a very high measure of GDP per capital, but millions of Americans ( a considerable amount are children) live in poverty.
Ernest
So poverty is not an easy social phenomenon to pin down neatly into one social realm or another.
Ernest
pls what is price ceiling
jasmine
its the max price a seller can charge for a product, mostly imposed by the government to protect the consumer
Luka
its the max price a seller can charge for a product, mostly imposed by the government to protect the consumer plus it must be imposed below the equilibrium price in order to be effective. A shortage will also be created after its imposition.

can happiness be measured?
Ylaine
Happiness is too subjective to be measured as an economic phenomenon or reality. I think that happiness happens at several levels of the human condition: biological, psychological, intellectual and at the level of the soul. How can economic theory be scientific about it?

about I have read of something called gross happiness index.

What is economies of scale
Jeremiah Reply
In microeconomics, economies of scale are the sum of total costs saved or that a firm has advantage over its competitors due to its scale of operations. More specifically, it is the firm's cost savings per unit of output that it gains as its production increases in scale.
