Q

Endogenous model

A
  • 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

Q

Covered interest rate parity

A

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

Q

Uncovered interest rate parity

A

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

25
Three accounts that make up country's balance of payments
Current, capital and financial account
26
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
27
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
28
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.
29
Impact on domestic currency | Expansionary monetary policy + expansionary fiscal policy with low capital mobility
domestic currency depreciates
30
Impact on domestic currency | restrictive monetary policy + expansionary fiscal policy with low capital mobility
indeterminate

31
Impact on domestic currency | restrictive monetary policy + restrictive fiscal policy with low capital mobility

32
Potential GDP
the maximum amount of output an economy can sustainably produce without inducing an increase in the inflation rate output level that corresponds to full employment with consistent wage and price expectations
33
Grinold-Kroner Model
E(r) = dividend yield + expected repricing + inflation rate + real economic growth - change in shares outstanding
34
Classical growth theory - economics
in the long run, the adoption of new technology results in a larger but not richer population, thus the standard of living is constant over time and there is no growth in per capita output
35
Increase in the savings rate under neoclassical model
implies higher capital-to-labor ratio (k) and higher output per worker (y) because a higher saving rate generates more saving/investment at every level of output
36
Increase in labor force growth (n) under neoclassical model
reduces equilibrium capital-to-labor
37
increase in Deprecation rate (o) under neoclassical model
reduces equilibrium capital-to-labor
38
Why are emerging market countries better able to influence their exchange rates
Their reserve levels as a ratio of average daily FX turnover are generally much greater than those of DM countries
39
What happens to foreign exchange reserves during currency crises
they decline
40
What happens to broad money growth during currency crises
they increase
41
Behavior of trade balance right before a currency crises
no change
42
Impact on domestic currency | expansionary fiscal policy | restrictive monetary policy with high capital mobility
currency appreciation
43
impact on domestic currency | expansionary monetary policy | restrictive fiscal policy with high capital mobility
currency depreciation
44
impact on domestic currency | expansionary monetary policy | expansionary fiscal policy with high capital mobility
ambiguous
45
impact on domestic currency | restrictive monetary policy | restrictive fiscal policy with high capital mobility
ambiguous
46
Relative to a normal distribution, the distribution of carry trade returns are more
peaked with negative skew
47
Are forward rates good predictors of forward spot rates
no
48
Under what time frame do international parity conditions hold
medium-to-long-term
49
Under what time frame do international parity conditions not hold
short-medium term
50
Formula under UIRP
inflation(foreign) - inflation(domestic)
51
which key determinant of exchange rates is absent in the Mundell-Fleming model
inflation rates
52
What two conditions must hold for real interest rate parity to hold
UIRP and ex ante PPP
53
Under UIRP, country with higher rates, what happens to their currency
depreciates
54
Formula for pure capital deepening
Growth in labor productivity - growth in TFP the larger the difference, the more important capital deepening is as a source of growth
55
Most important factor in long-term stock market growth
Growth in GDP
56
Club convergence
The idea that only rich and middle income countries sharing a favorable set of characteristics (part of the club) will converge to the income level of the richest countries The club includes institutional structures, property rights, political stability, etc.
57
Absolute convergence
The idea that all countries will eventually converge to the same gdp per capita output
58
Conditional convergence
The idea that countries will only catch the richest countries if they have the same savings rate, population growth rate, and production function
59
Douglas-Cobb Function
Y(L,K) = AL^y * K^x Y - total production A - total factor productivity L - labor K - capital The premise is constant returns to scale, and does display diminishing returns to scale
60
Regulatory Competition
When regulators compete to provide a more conducive environment for businesses
61
Regulatory Capture
Regulation arises to enhance the interests of the regulated
62
Independent Regulators
Regulators recognized and granted authority by the government. They are not part of the government and do not rely on government funding
63
Self-regulating Bodies
Private, non-government bodies that both regulate and represent their members. Some SROs are also independent regulators
64
Self-regulating organization
Self-regulating body given authority by the government
65
Coase Theorem
If an externality can be traded and there are no transaction costs, then the allocation of property rights will be efficient
66
Substantive Law vs. Procedural Law
Substantive focuses on the rights and responsibilities of entities and relationships of entities, while procedural focuses on the protection and enforcement of substantive laws
67
GDP Growth Rate
1) Long-term growth rate of technology + (x * long-term growth rate in capital) + (1-x) * (long-term growth rate in capital) 2) Long-term growth rate of labor force + long-term growth rate in labor productivity
68
Sustainable growth of output per capita under neoclassical model
Growth rate in technology / labor's share of GDP (1-a)
69
Sustainable growth rate of output under neoclassical model
sustainable growth rate of output per capita + growth of labor
70
Adverse Selection
When sellers have information that buyers do not
71
The correlation between the ownership of natural resources and subsequent real GDP growth
insignificant, but not different from 0
72
Growth due to TFP
growth from labor productivity - capital deepening
