(Continued with question 1 in exercise for chapter 3). Suppose instead of given 2000 there is an investment function which takes the form Above, i is the interest rate. Meanwhile there is a demand function for money Md=1.2Y-20000i Assume that the monetary base is equal to 2000 while the required reserve ratio is 1 ).

I guess I have to come out to reply to those who concern with the nature rate of unemployment First, What is the natural rate of unemployment? It is assumed to be the unemployment rate at the steady state or equilibrium. Note that equilibrium here is not referred to the common

The Data of macroeconomics It is a capital mistake to theorize before one has data Insensibly one begins to twist facts to suit theories, instead of theories to fit facts. Sherlock holmes Scientists, economists, and detectives have much in common: they all want to figure out what's going on in the world around them. To do this, they rely on both theory and observation. They build theories in an attempt to make sense of what they see happening. They then turn to more systematic observation to eval- uate the theories validity. Only when theory and evidence come into line do they feel they understand the situation

National Income: Where t comes From and where丨 t Goes A large income is the best recipe for happiness I ever heard of. Jane Austen The most important macroeconomic variable is gross domestic product(GDP) As we have seen, GDP measures both a nations total output of goods and ser- vices and its total income. To appreciate the significance of GDP, one need only take a quick look at international data: compared with their poorer counterparts, nations with a high level of gDP per person have everything from better child-

1. GDP measures both the total income of everyone in the economy and the total expendi- ture on the economy's output of goods and services. GDP can measure two things at once because both are really the same thing: for an economy as a whole, income must al expenditure. As the circular flow diagram in the text illustrates, these are alter- native, equivalent ways of measuring the flow of dollars in the economy

Unemployment A man willing to work, and unable to find work, is perhaps the saddest sight that fortune's inequality exhibits under the sun Thomas Carlyle Unemployment is the macroeconomic problem that affects people most directly and severely. For most people, the loss of a job means a reduced living standard

The question of growth is nothing new but new disguise for an age-old issue, one which has always intrigued and preoccupied economics: the present versus the future. -James Tobin If you have ever spoken with your grandparents about what their lives were like when they were young, most likely you learned an important lesson over about economics: material standards of have improved substantially over form time for most families in most countries

Economic growth‖ Is there some action a government of India could take that would lead the Indian economy to grow like Indonesia's or Egypt's? If so, what, exactly? If not, what is it about the \nature of India that makes it so? The conse- quences for human welfare involved in questions like these are simply stag- gering: Once one starts to think about them, it is hard to think about Robert E. Lucas, Jr
