Rate and Reserve Ratio, selling of Treasuries and more lending via the Term Auction Facility Flat Tax: rate of tax that remains constant despite taxable amount Progressive Tax: tax rate that intensifies as taxed amount increases Effective Tax Rate: tax/taxable amount Lump Sum Tax: tax that remains the same regardless of income Subsidy: when gov. helps pay for certain activity (negative tax) C A L I F O R I N I A ID A H O Compute r 50 25 0 10 5 0 Potato 0 50 100 0 62 125 Comparative Advantage: when a country can make a product with a lesser opportunity cost Tariff: port toll charged on imports Reciprocal Trade Agreement Act: a simplified and more favorable set of trade rules, most favored nation status, the US extends to nations who engage in bi-lateral trade talks with US Gen. Agree. On Tariffs & Trade: international convention to simplify trade and reduce barriers World Trade Organization: international organization to remedy trade disputes and foster world trade Growth Compounding: when growth portions are added to the initial principal to further perpetuate future growth Rule of 70: number of periods to double = 70/growth rate –orgrowth rate = 70/number of periods to double
