Q

BOP - Capital (financial) account

Q

dornbusch overshooting model

A

output prices are sticky in the short run but fully flexible in the long run.
expansionary monetary policy increases the real money supply and prices are slow to react in the rt. This causes the nominal and real exchange rates to depreciate. exchange rates gradually increase towards their pp implied values

A

24
Q

ex-ante version ppp (expected)

A

CIP holds > if FRP hold, UCPI hold
int. rate diff should mirror inflation diff. if IFR hold.
If ex-ante Rppp & IFR hold, UCPI holds.

25
Q

warning sign of currency crisis

A

terms of trade deteriorate
fixed or partially fixed exchange rates
official fx reservers dramatically decrease
currency value that has risen above its historical mean
inflation increase
liberalized capital mkt, that allow for free flow of capital
MS. relative to bank reserves increase
bankrupt rises

26
Q

change in price

A

= change in GDP + change in (E/GDP) + CHANGE IN (P/E)

27
Q

COBB-DOUGLUS PRODUCTION FUNCTION Y=

constant return to scale

A

TK^aL^(1-a)

diminishing marginal productivity of capital

28
Q

Cobb-Douglas Production Function
y=
constant return to scale

A

TK^aL^(1-a)

29
Q

growth rate in potential GDP

A

=LT growth rate of tech + a(LT growth of capital) +
(1-a)(LT growth rate of Labor)

= LT growth rate of labor force + LT growth rate in labor productivity — this is capital deepening & tech progress

30
Q

Dutch diese

A

global demand drives up currency value, making export more expensive

large endowments of natural resources

31
Q

Labor supply factors

A

demographics
labor force participation = labor force/working age population
immigration
avg/hour worked

32
Q

classical growth theory

A

LT
Population growth increase whenever there are increases in per capital income above substance level (population explosion occur) due to an increase in capital or tech progress.

growth in real GDP/capital is NOT permanent.
lead to diminishing marginal return to labor
reduce productivity and GDP/capital

33
Q

neoclassical growth theory

A

focus on estimating the economic’s LT steady state growth of rate.
at equilibrium economy when output - to-capital is constant g

Neoclassical growth theory concludes that capital accumulation affects the level of output but not the long-run growth rate.

population growth is independent of economic growth

34
Q

g*

A

= TPF/(1-a)

35
Q

g*

A

= θgrowth rate in technology/(1-a)

36
Q

G*

A

TFP/(1-a) + change in L

g* + ∆L

37
Q

Endogenous growth theory

A

technological growth emerges as a result of investment in both physical and human capital

permanently increase rate of growth for increase in investment

RIO are constant
increase in savings will permanently increase the growth rate

economies of scale

38
Q

convergence hypothesis - absolute

A

less developed countries will achieve living standard over time

39
Q

convergence hypothesis - conditional

A

convergence in living standard will only occur for countries with the same savings rates, population growth rate, and production functions.
growth higher for less developed countries until they catch up

40
Q

convergence hypothesis - club

A

poorer countries that are part of the club will grow rapidly to catch up with their richer peers

41
Q

regulatory capture

A

a regulatory body be influenced or even possibly controlled by the industry the is being regulated

42
Q

regulatory competition

A

regulators compete to provide the most business-friendly environment

43
Q

regulations intervention

A
price mechanism(Taxes and subsidie)
restricting or requiring certain activities
provision of public goody on financing of private project
44
Q

Self-regulatory bodies (SRBs)

A

do not have government recognition, and they represent as well as regulate their members.

45
Q

Self-regulating organizations (SROs)

A

are SRBs that are given government recognition and authority.

46
Q

net regulatory burden

A

Regulatory burden minus the private benefits of regulation

47
Q

(rd − rf) > (Forward − Spot) / Spot

A

then Borrow Foreign

48
Q

(rd − rf) < (Forward − Spot) / Spot

A

then Borrow Domestic

49
Q

The adjustment to exchange rates to restore current accounts to a balanced position depends on:

A

The level of initial deficit.
The response of import and export demand to changes in import and export prices.
The response of import and export prices to changes in the exchange rate.

50
Q

Regulatory arbitrage occurs when

A

the firms exploit the difference between the economic substance and interpretation of a regulation.

51
Q

Capital deepening = labor productivity - tfp

A

is an increase in the capital-to-labor ratio. Due to diminishing marginal productivity of capital, increases in the capital per worker can lead to only limited increases in labor productivity if the capital-to-labor ratio is already high.

52
Q

The objectives of regulators in financial markets include

A

prudential supervision, financial stability, market integrity, and economic growth.

53
Q

High-quality cash flow is characterized by

A

positive OCF that is derived from sustainable sources and is adequate to cover capital expenditures, dividends, and debt repayments.

54
Q

debt sustainability channel

A

there should be some upper limit on the ability of countries to run persistently large current account deficits.

55
Q

flow supply/demand channel mechanism

A

focuses on the fact that purchases and sales of internationally traded goods and services require the exchange of domestic and foreign currencies in order to arrange payment for those goods and services.

Such shifts in currency demand should exert UPWARD pressure on the value of the surplus nation’s currency and downward pressure on the value of the deficit nation’s currency.

56
Q

portfolio balance channel

A

assumes that current account imbalances shift financial wealth from deficit nations to surplus nations. Countries with trade deficits will finance their trade with increased borrowing. This behavior may lead to shifts in global asset preferences, which in turn could influence the path of exchange rates.
