Key Economic Indicators Explained

Gross Domestic Product (GDP)

GDP represents the market value of all officially recognized final goods and services produced within a country during a specific period.

Debt and Equity Financing

Debt financing: This is when you borrow money from a bank or a financial institution, such as through bonds.

Equity financing: This is when you offer a portion of your company, such as stocks, in exchange for capital. You don't have to pay the money back, but you give up a portion of ownership.

• Bonds: Less risky with lower returns. The return of your money plus interest is guaranteed. Bonds are issued by companies, governments, etc. They are fixed-income securities, with the issuer being the borrower.
• Stocks: More risky with potentially higher returns. However, you assume the risk of the company not being successful.

Equity

• Additional paid-in capital: Capital that shareholders have contributed to the company above the nominal

Ricardian Model

Unit Labour Req.  Pears(Ib).  Oranges(Ib)

Home                  4h (aLp).         3h (aLo)

Foreign.              6h (aLp*).        1h (alp*)

Absolute Advantage - country takes less time to produce goods?

Home -> pears // Foreign -> oranges

Comparative Advantage - lower opportunity cost 

- Home has a C.Adv in pears production as its opp. cost of pears production is lower than foreign country - will specialize in pears

PPF (grafico) - (aLp · Qp) + (aLo · Qo) <= L

4Qp + 3Qo <= L (Qp = 300 & Qo=400)

Maximum home pears production is 300 and oranges 400

Slope = opp. cost - the opp. cost of pear is how many pounds of oranges Home must stop producing in order to make one more pound of pear
