(Done) Day 1,2: Measuring the economy, long-run growth Flashcards
What’s free market?
- Buyers and sellers interact freely (with little gov’t intervention)
- No central planning: production and distribution are the result of individual choices, no “coordination from above” aka the gov’t.
- economy coordinated through prices
What’s microeconomics?
Focuses on the study of the individual: people, firms, or markets
What’s macroeconomics?
- aggregate level
- Studying the collections of people and firms and how their interactions through markets determine the overall economic activity in a country/region
What’s the difference between long-run and short-run?
long-runs usually greater than 6months/1 year
What’s macro policy?
used to stabilize the economy and prices, and increase employment/growth
examples of macro topics?
economy-wide topics: GDP, growth rate, unemployment rate, etc.
What’re macro research steps?
- Gather the economic facts/data you want to explain/explore
- develop model to explain those facts
- compare model’s predictions with original facts
- use the model to make policy/run experiments (change parameters)
What should a successful model do?
A successful model should make general and quantitative predictions: 1. predict differences between firms/countries
2. AND by how much (numerically)
- explain relationships between macro topics
What’s a model?
- simplify reality by making assumptions
2. identify the most relevant drivers of the economic facts you’re exploring
Are models realistic?
NEVER! The whole point of a model is to simplify reality and identify the most relevant drivers of the economic facts you’re exploring
What’re models in econ made up of?
Models in econ consist of a set of math equations that summarize the main interactions we care about, and a set of unknowns (the endogenous variables). You solve the model by solving the equations for the values of the unknowns.
What’s a parameter?
variable that’s fixed over time unless you change it yourself (doesn’t change by itself over time)
input to the model
What’s exogenous variable?
- input to model that’s allowed to change/vary over time, variations occur naturally
- Driving the model and the results
What’s endogenous variable?
output, result of model
What’s national income accounting?
measuring GDP
What’s the national income accounting equation?
total production (of goods/services) = total income = total spending
What’s GDP?
GD{ is the value of goods/services produced in a country
- within its borders
- for final use
What do u need to count GDP?
- unit of account
- common assessment method
- avoid double counting
what’s unit of account?
a standard monetary unit of measurement of value/cost of goods, services, or assets.
how to avoid double counting GDP?
To avoid double counting, GDP counts only the final output of goods and services, not the production of intermediate goods used as inputs to make final goods (eg raw materials).
What’s added value used for?
Use added value to calculate an individual person/firm’s contribution to GDP! Use the sum of an economy’s value added for total GDP.
What’s added value?
Use added value to calculate an individual person/firm’s contribution to GDP! Use the sum of an economy’s value added for total GDP.
Formula for added value?
value created/added value is = value of final goods/services sales - value of intermediate products (see above).
What does value added include?
wages, interest, depreciation, rent, taxes, and profit (usually splits into just profits + wages in most basic scenarios)
What’s productivity?
How good you are at producing added value per hour
productivity formula?
Productivity = Added value / Hours
