“The FOMC is firmly committed to fulfilling its statutory mandate from the Congress of promoting maximum employment, stable prices, and moderate long-term interest rates.”
FOMC statement of longer-run goals and policy strategy, January 25 2012
Why the Change in Language? (Maybe the Federal Reserve Act has something to do with it?)

Basic Growth Accounting: Connecting a Few Dots
GDP growth = Productivity growth + Capital stock growth
+ Employment growth (If productivity growth is “exogenous” and if the capital stock changes slowly, pursuing maximum employment is roughly equivalent to pursuing maximum sustainable growth.)
![Page 9: Lecture 1 -- National Income Accounting Autumn 2014](https://reader034.vdocuments.us/reader034/viewer/2022042618/577cc0e41a28aba711917db7/html5/thumbnails/9.jpg)
Our Mission
To make sense of this statement. 1. Build a model that helps understand
how output, employment, prices, interest rates (and other stuff) are determined.
![Page 10: Lecture 1 -- National Income Accounting Autumn 2014](https://reader034.vdocuments.us/reader034/viewer/2022042618/577cc0e41a28aba711917db7/html5/thumbnails/10.jpg)
Our Mission To make sense of this statement. 2a. Figure out what it means to set the
funds rate in the range of 0 to ¼ percent (or anything else for that matter).
2b. Figure out all that other stuff the Fed has been up to.

Our Mission
3. Help the FOMC
get it right next time.

Gross Domestic Product
Gross Domestic Product is a measure of the value of all final goods and services newly produced within a specified country’s borders during a specified period of time (usually one year or one quarter).
![Page 13: Lecture 1 -- National Income Accounting Autumn 2014](https://reader034.vdocuments.us/reader034/viewer/2022042618/577cc0e41a28aba711917db7/html5/thumbnails/13.jpg)
HOW IS GDP MEASURED?
![Page 14: Lecture 1 -- National Income Accounting Autumn 2014](https://reader034.vdocuments.us/reader034/viewer/2022042618/577cc0e41a28aba711917db7/html5/thumbnails/14.jpg)
Three ways to capture total (aggregate) economic activity
We can measure GPD in market “values” from three “theoretically” identical measures:
1. How much is produced.
2. How much is earned.
3. How much is purchased.
![Page 15: Lecture 1 -- National Income Accounting Autumn 2014](https://reader034.vdocuments.us/reader034/viewer/2022042618/577cc0e41a28aba711917db7/html5/thumbnails/15.jpg)
The circular flow concept
Everything produced is an income source to someone.
Everything produced is paid for (is an expenditure) by someone.
![Page 16: Lecture 1 -- National Income Accounting Autumn 2014](https://reader034.vdocuments.us/reader034/viewer/2022042618/577cc0e41a28aba711917db7/html5/thumbnails/16.jpg)
Everything produced, is purchased by someone…
Total Production = Total Expenditure
![Page 17: Lecture 1 -- National Income Accounting Autumn 2014](https://reader034.vdocuments.us/reader034/viewer/2022042618/577cc0e41a28aba711917db7/html5/thumbnails/17.jpg)
Gross Domestic Product: The Expenditures Approach
Y = C + I + G + (X - M)
To calculate GDP:
Exports
Investment
Consumption Government Purchases
Imports

Problems with GDP as a measure of welfare
Let’s stipulate that we want to talk Real, Per Capita GDP. GDP still falls short because income per se does not generate “happiness”, or “well-being.”

The HDI is based on: 1. Long and healthy life --- Life expectancy
2. Access to knowledge --- Mean adult educational attainment --- Expected years of education for children of school entrance age
3. Standard of living --- Gross national income

The Genuine Progress Indicator Consumption + (consumer durable services
+ services of highways and streets + net investment (not foreign-financed)) X discount for
income inequality
+ value of time in leisure, parenting, volunteering, education
- value of leisure lost in working and commuting - social costs of pollution (including noise), loss of
wetlands, farm land, forests, depletion of nonrenewable resources
- household costs of pollution abatement, crime and crime prevention
- cost of unemployment (value of “unwanted” leisure)

• GDP growth is arguably highly correlated with underlying economic welfare
• We will generally think of growth in the
level of GDP as a reasonable indicator of economic progress, bearing in mind all appropriate caveats

Macroeconomics in 6 Easy Bullet Points
![Page 45: Lecture 1 -- National Income Accounting Autumn 2014](https://reader034.vdocuments.us/reader034/viewer/2022042618/577cc0e41a28aba711917db7/html5/thumbnails/45.jpg)
Macro in Bullet Points
1. Ultimately, fundamentals (not
demand) determine GDP.
(If “tighter” monetary policy slows down the economy, something isn’t working right.)
![Page 46: Lecture 1 -- National Income Accounting Autumn 2014](https://reader034.vdocuments.us/reader034/viewer/2022042618/577cc0e41a28aba711917db7/html5/thumbnails/46.jpg)
Macro in Bullet Points
2. In the end, interest rates are
determined in the market for goods and services.
(Interest rates are low, but mostly it isn’t because of the Fed – or at least not for the reason you might think.)
![Page 47: Lecture 1 -- National Income Accounting Autumn 2014](https://reader034.vdocuments.us/reader034/viewer/2022042618/577cc0e41a28aba711917db7/html5/thumbnails/47.jpg)
Macro in Bullet Points
3. Prices are what they are (neither
necessarily good nor necessarily bad).
(Right now, rising interest rates would look like a good thing.)
![Page 48: Lecture 1 -- National Income Accounting Autumn 2014](https://reader034.vdocuments.us/reader034/viewer/2022042618/577cc0e41a28aba711917db7/html5/thumbnails/48.jpg)
Macro in Bullet Points
4. The future is now (expectations
rule).
(The impact of any particular fiscal or monetary policy depends not on the government does today, but on what people expect it to do down the road.)
![Page 49: Lecture 1 -- National Income Accounting Autumn 2014](https://reader034.vdocuments.us/reader034/viewer/2022042618/577cc0e41a28aba711917db7/html5/thumbnails/49.jpg)
Macro in Bullet Points
5. Inflation is everywhere and always a
monetary phenomenon.
(But it’s complicated: Maybe all that money the Fed printed doesn’t matter.)

Macro in Bullet Points
6. A higher funds rate does not
necessarily mean monetary policy is getting “tighter.”
(Maybe it does, maybe it doesn’t!)
