Economics Flashcards
Dutch disease
currency appreciation driven by strong export demand for resources makes other segments of the economy, in particular manufacturing, globally uncompetitive
Neoclassic model
Sustainable growth rate of an economy is a function of population growth, labor share of income, and rate of technological advancement. Growth from savings is temporary
Endogenous model
- no diminishing marginal returns to capital for the economy as a whole
- increasing the saving rate permanently increases the rate of economic growth
-production function = y(e) = f(k(e)) = c*k(e), where y(e) is output per worker, k(e) = capital per worker, c is constant - growth rate of output per capita = delta y(e) = delta k(e) = s*c-o-n, where s is savings rate, c is constant, o is depreciation, n = labor force growth
capital-labor ratio
an increase in the capital-labor ratio, moving along the production function to the right
capital deepening
adding more and more capital to a fixed number of workers increase per capita output, but at a decreasing rate
effect of capital deepening on country with high capital-labor ratio and low marginal product of capital
little impact because of diminishing returns
effect of population growth on gdp growth and per capita gdp growth
increases gdp growth, but no effect on per capita gdp growth
a country with high capital-labor ratio and low marginal product of capital will increase growth in gdp per capita through what?
technological progress
indicators of dutch disease
high export demand for natural resources and high currency appreciation
The key international parity conditions
1) Covered interest rate parity
2) Uncovered interest rate parity
3) Forward rate parity
4 Purchasing power parity
5) International fisher effect
Covered interest rate parity
Investment in a foreign money market instrument that is completely hedge against exchange rate risk should yield exactly the same return as an otherwise identical domestic money market instrument
If the forward and spot exchange rates, as well as one of the risk-free rates are known, the other risk-free rate can be calculated
Uncovered interest rate parity
The proposition that the expected return on an uncovered (unhedged) foreign currency (risk-free) investment should equal the return on a comparable domestic currency investment
Given the spot exchange rate and the expected future change, the future spot exchange rate can be calculated
Forward Rate Parity
Forward exchange rate will be an unbiased predictor of the future spot exchange rate
Not a perfect forecast, just an unbiased one
Why uncovered interest rate parity prediction will not hold
there is no arbitrage condition that forces uncovered interest rate parity to hold
Using forward points to forecast exchange spot rate assumes what about investors
they are risk neutral
Purchasing power parity (PPP)
Exchange rates move to equalize the purchasing power of different currencies
Absolute version of PPP
prices of goods and services will not differ internationally once exchange rates are considered
Relative version of PPP
changes in nominal exchange rates over time are equal to national inflation rate differentials
Real interest rate parity
Real interest rates will converge to the same level across different markets
International fisher effect
nominal interest rate differentials across currencies are determined by expected inflation differentials
Forward rates are unbiased predictors of future spot rates if which two parity conditions hold
Covered interest rate parity and uncovered interest rate parity
International fisher effect requires which parities to hold
ex ante PPP and real interest rate PPP
FX carry trade
Investment strategy that involves taking long positions in high-yield currencies and short positions in low-yield currencies
Carry trades will be profitable when which parity does not hold
uncovered interest rate parity, in the short or medium term
Three accounts that make up country’s balance of payments
Current, capital and financial account
Impact of exports>imports on current account and capital account
Negative current account and current account deficit, must make it up with a surplus in capital account
Impact of long-term current account deficit on currency
Currency will depreciate because that country is financing their acquisitions of imports through the continued use of debt
Why do investment/financing decisions usually dominant exchange rate movements
1) Prices tend to adjust slowly than exchange rates
2) Product of real goods and services takes time, while liquid financial markets allow virtually instant redirection of financial flows
3) Current spending/production reflects purchases and sales of current production while investment/financing decisions reflect reallocation of existing portfolios
4) Expected exchange rate movements can induce very large short-term capital flows.
Impact on domestic currency | Expansionary monetary policy + expansionary fiscal policy with low capital mobility
domestic currency depreciates
