14Perfect Competition (Classical Macro)
1) Price-takers, passively respond to market price, no market power to set the market W or P
2) [blank_start]Homogeneous[blank_end] product, workers
3) No [blank_start]barriers[blank_end] to exit or entry
4) [blank_start]Large[blank_end] number of companies/consumers/workers
5) [blank_start]Perfect[blank_end] information, perfect foresight- AHomogeneous
- Bbarriers

15Imperfect Competition (Keynes' Macro)
1) Price-makers, significant market power; 4-firm ratios of 20-30% of market enough for significant market power
2) Product [blank_start]differentiation[blank_end] is a conscious marketing strategy
3) Significant market barriers to [blank_start]entry[blank_end]
4) Many industries, only a [blank_start]few[blank_end] large firms
5) Uncertain – information is costly and not necessarily reliable; future [blank_start]cannot[blank_end] be known- Adifferentiation

16PPF stands for [blank_start]Production[blank_end] Possibility Frontier. It refers to the [blank_start]supply[blank_end] side of the economy. A hidden assumption is that there is [blank_start]full[blank_end] resource utilization. To figure out PPF, we need to know resources (land, labor, capital), technology, and institutional context.
- AProduction
- Bsupply
- Cfull
17Real Capital ([blank_start]K[blank_end]) is the produced means of production such as equipment, physical plant (land, factory, buildings, etc.), and inventories (raw materials, or semi-finished products or materials).
- AK
18For using PPF and graphing the changes in it:
- Move along: [blank_start]Change[blank_end] in people’s choices (preferences), Companies choose to [blank_start]reallocate[blank_end] resources, increase in one and decrease in another
- Shift in or out (left or right): based on the “givens”: resources, technology, institutions; either symmetric or asymmetric
- Operate under the PPF: under utilization of the resources, [blank_start]below[blank_end] the curve, not reaching full potential- Areallocate
- BChange
- Cbelow
19What is the formula for percent change?
([blank_start]final[blank_end]/[blank_start]initial[blank_end] -1) * [blank_start]100[blank_end]- Afinal
- Binitial
- C100
20What is the formula for finding Real Variable?
([blank_start]Nominal[blank_end] Variable/P index)*[blank_start]100[blank_end]- ANominal
- B100
21adjustable-rate mortgages – usually permit a 2 %-point increase in i in any year. ARMs are not a perfect protection against inflation.
- AVerdadeiro
- BFalso
22Direct lending is through the bond market. Borrowers sell bonds, lenders buy bonds, and that cuts out the banking intermediaries. That’s why this is called [blank_start]disintermediation[blank_end]. Bond issuer decides on Face value, term value of bond. Bond-holders find that the Pb ([blank_start]price[blank_end] of the bond on the market) tends to [blank_start]fall[blank_end] when inflation heats up because higher inflation means higher nominal i. Formula for determining face value of bonds are Pb (1+i) = Pfv.
- Adisintermediation
- Bprice
- Cfall
23Inflation is the [blank_start]increase[blank_end] of prices and assets. Deflation is the opposite and it [blank_start]increases[blank_end] the burden of debt. Both are bad to have.
- Aincrease
- Bincreases
24To count as unemployed, you have to be [blank_start]available[blank_end] to work full-time, not employed, and [blank_start]actively[blank_end] seeking employment. “[blank_start]Workforce[blank_end]” means those who are employed. “[blank_start]Labor[blank_end] force” means those who are potentially employed, but includes currently unemployed. If you are a [blank_start]discouraged[blank_end] worker (given up looking for a job) you are not in the labor force. If you are a full-time [blank_start]student[blank_end] you are not in the labor force. Homemakers are considered [blank_start]available[blank_end] to work full-time and [blank_start]prison[blank_end] population is not available to work.

25Business cycles last 2-11 years. Expansion (of output) is about 3x length of recession/contraction (of output). Recession is defined as 2 sequential quarters of decline in output. Peak is the high point of output. Trough is the low point for output.
- APeak
- BRecession
- CTrough
- DExpansion
26Layoffs are considered [blank_start]cyclical[blank_end] U – workers are laid off and await recall. Their job will be there again when the economy picks up. Depressions—they last 11-26 years, but spaced 40-60 years apart. Hit hard the advanced capitalist countries, especially the [blank_start]upstart[blank_end] country. Seasonal U – we know there are recurring patterns of [blank_start]higher[blank_end] U in the summer and in January/February after the holiday sales boom.
- Acyclical
- Bupstart
- Chigher
27[blank_start]Cyclical[blank_end] unemployment is when people are laid off (company plans to rehire you when economy turns up). It’s a cyclical downturn. Frictional U – search for a new job by worker and employer takes [blank_start]time[blank_end], not a frictionless world. Especially true for new entrants, some jobs become vacant when people retire, quit, are fired. Has to do with job turnover, and LF turnover. Structural U – when there’s a [blank_start]mismatch[blank_end] between the workers looking and the jobs available. Mismatched skills, mismatched locations.
- ACyclical
- Btime
- Cmismatch
28What is the formula for finding incidence unemployment rate?
U rate = [blank_start]incidence[blank_end] rate * [blank_start]duration[blank_end]- Aincidence
- Bduration

30Demand is [blank_start]downward[blank_end]-sloping because of preferences and affordability. Substitution effect: as an item becomes [blank_start]cheaper[blank_end], it becomes worth it to buy more of that item, less of a substitute. Income effect: as an item becomes cheaper, you can afford to buy [blank_start]more[blank_end] of it.
- Adownward
- Bcheaper
- Cmore
31Supply is [blank_start]upward[blank_end]-sloping because of [blank_start]congestion[blank_end], as you try to supply more and hire more resources, you only have so much room in your workplace.
- Aupward
- Bcongestion
32Diminishing marginal utility of goods, or rising marginal disutility of saving, the less you are consuming and more you are saving, the harder it is to give up more present consumption and save unless without a good [blank_start]incentive[blank_end].
- Aincentive
33What are some leakages for households and businesses (firms) in the circular flow diagram?
- AIndirect business taxes

35There are three approaches for GDP accounting. [blank_start]Product[blank_end] Approach is GDP = C + I + G + (EX-IM) = C + I + G + NX. [blank_start]Income[blank_end] approach is GDI = [W’s + distributed profits + interest + rent] + [CCA + retained profits] + indirect business taxes (e.g., payroll taxes) = GDP. [blank_start]Value[blank_end]-added Approach is value added at any stage of production = Value of that output minus the value of direct produced inputs at that stage of production.
- AProduct
- BIncome
- CValue
36Perfect Competition, embraces [blank_start]laissez-faire[blank_end], or the government letting the economy alone. From that perspective, the invisible hand of the market process works because the economy is an egalitarian and fair playing field. Small Mom & Pop grocery stores. Imperfect Competition believes there are large corporations with significant market power, but they are still technologically constrained, just like smaller firms. They think there are natural [blank_start]limits[blank_end] on firms’ size. Imperfect Competition agrees with PC that consumers are unconstrained rational individuals freely making [blank_start]choices[blank_end]. Strategic Competition believes that large corporations rather than individuals are [blank_start]unconstrained[blank_end], companies seem to be able to expand without constraint into larger and larger conglomerates. Therefore more extensive government [blank_start]intervention[blank_end] on the supply side as well as demand side is necessary. Also, consumers’ households are constrained by the need to earn a living, since most have no independent means of support.
- Alaissez-faire
- Blimits
- Cchoices
- Dunconstrained
- Eintervention
37Additional HIDDEN assumptions we need to make explicit, to differentiation PC/IC from Strategic Competition and Keynes: PC/IC side
6) Owner/Operator (“the firm”)
7) Diminishing returns: Given fixed K stock (factory, equipment, plant), more employees are hired, workplace gets [blank_start]congested[blank_end], and productivity (output/hour) [blank_start]declines[blank_end] .
8) Companies [blank_start]maximize[blank_end] (short-run) profits
9) Companies pay for, people sell their labor-services or work on the labor market
10) Atomistic Rational individuals [blank_start]maximize[blank_end] their well-being (utility)
subject to constraints of initial endowments
11) WORLDVIEW: INDIVIDUAL, and CHOICE PREVAILS- Acongested
- Bdeclines
- Cmaximize
- Dmaximize
38Additional HIDDEN assumptions we need to make explicit, to differentiation PC/IC from Strategic Competition and Keynes: Strategic Comp version
6) [blank_start]Separation[blank_end] between ownership and management, so potential conflict of interest between owners and managers (or different objective functions, i.e., goals); it matters for differentiating financial from real investment
7) Constant returns:
There is typically [blank_start]excess[blank_end] capacity (unutilized equipment). Manager has choices – shifts, overtime. Given an optimal staffing ratio for equipment. For K/L, you expand output by expanding the hours each piece of equipment is used.
8) Strategic companies seek [blank_start]long[blank_end]-run profitability, willing to sacrifice short-run profits for long-run gain. Investment reflects such long-run strategic planning, not a short-run profit-maximization algorithm; matters for real investment, and for business failures
9) people sell their time and potential on the labor market, companies hire and pay for a resume, for workers’ potential. Actual labor-services are performed at work. It’s management’s job is to make sure there is the appropriate level of work intensity and quality of work performance
10) Choices are made by [blank_start]households[blank_end] of a given class, which have needs, are socially constrained and motivated, and depend on the internal dynamics of household itself
11) HOUSEHOLDS/CLASSES in social context, and NEEDS PREVAIL

39Stocks vs. Flows - What are stocks?
- Atotal wealth or savings inherited from the past
- Ba stock/share in a company
- Cshort-term wealth or saving, from a quarter or past year
40Stock vs. Flow - What are flows?
- Atotal wealth or savings are inherited from the past
- Bshort-term, can be decided today, from a given year
41A flow of [blank_start]saving[blank_end] (per year) is amount of money a household puts aside in a given year for repaying debt or increasing wealth while a stock of [blank_start]saving[blank_end] is past accumulation of saving. A flow of [blank_start]investment[blank_end] is the amount of money businesses put into increasing/replacing worn out plant, equipment, and inventories while a stock of [blank_start]capital[blank_end] is amount of plant, equipment, and inventories accumulated from the past.

42Keynes’ Theory of Investment – different from Neoclassical. I is the most volatile part of GDP. The [blank_start]timing[blank_end] of investment is just as important as the incentive to invest. Driven by competitive process in your industry, companies need to I to stay alive as a going concern, the decision question is timing (less about if, more about how much and when).
- Atiming
43Classical theory of saving: you’re only willing to save more if you’re paid a [blank_start]higher[blank_end] interest rate – theory of time preferences. Keynes: In fact, households save because they have [blank_start]needs[blank_end] as households, not individuals; we are mortal, we have a life-cycle (raise a family, buy a house, send kids to college, retire). It smooths the income received, despite the fact that prime age to work is 22-60. Life-Cycle Hypothesis – people need to [blank_start]save[blank_end] over their life for big-ticket items like cars, homes, college education, or for when you won’t have income coming in – retirement. Permanent-Income Hypothesis – people’s [blank_start]expenditures[blank_end] depend on their average or usual income, not temporary rises or falls. Substitution effect: [blank_start]higher[blank_end] price of something leads to change in quantity you choose. Income effect: [blank_start]higher[blank_end] P of something means you can “afford” a different amount.

44The Saving Function: S = Sa + mpsY(d). Sa is [blank_start]autonomous[blank_end] saving, mps is marginal propensity to save. mps is the [blank_start]slope[blank_end] of the saving function where (change of S/change of Y).
- Aautonomous
- Bslope
45The Consumption function can be derived from the saving function. C = Ca + mpcY.
Ca is autonomous [blank_start]consumption[blank_end]. Ca = -Sa. mpc is marginal propensity to consume (1-[blank_start]mps[blank_end]) and Y is income.- Aconsumption
- Bmps
46The Aggregate Expenditure (AE) function is AE = C+I+G+NX(EX-IM). It can also be written as AE = [blank_start]A[blank_end] +mpcY where mpcY is induced AE.
- AA
47So Production = demand
So y = GDI = GDP = AE
Or [blank_start]Ys[blank_end] = AE
Slope of Ys = [blank_start]1[blank_end]- A1

48PC/IC has [blank_start]Diminishing[blank_end] Returns in L market, full K [blank_start]utilization[blank_end] and [blank_start]Short[blank_end]-run profit maximization. While Strategic has [blank_start]Constant[blank_end] returns, [blank_start]excess[blank_end] capacity and Strategic choices for [blank_start]long[blank_end]-run/sustainable profitability. Diminishing returns are as the company highers more people there is an increase in labor hours while the MPL (marginal product of labor) is diminishing. MPL is change of output/change of labor hours so APL (average product of labor = total output/total labor-hours) is also diminishing. That means there will be rising costs.

49Equilibrium will be where both conditions are met, where the two lines [blank_start]cross[blank_end]. There is no further tendency to [blank_start]move[blank_end].
- Amove
- Bcross
50The Income Tautology formula is Y = C + S + T, or Y = C + S.
- AVerdadeiro

- BFalso
54What affects GDP?
- AFinal products produced
- BProducts produced before
- CFinal output
- DFinal output when it was first produced/sold
55What is the value added-approach?
- ATotal expenditures at each stage of the production process are added up to calculate total value produced.
- BThe value of output plus the value of inputs equals total value created.
- CThe value of output minus the value of intermediate goods is added up across all sectors.
- DSum up the value created in each sector over all sectors.
56What is autonomous saving?
- AWhat you spend when your income is 0.
- BWhat you automatically save after each paychecl
- CWhat the bank automatically deposits into your saving
- DA fixed amount saved each time
57If there is dissaving, then what can be said about the relationship of consumer spending to personal income?
- AConsumer spending > personal income
- BConsumer spending < personal income
- CConsumer spending = personal income
58What is the definition of equilibrium in macroeconomics?
- AA situation in which equilibrium price has brought quantity supplied equal to quantity demanded in all markets.
- BA situation from which there is no tendency to move.
- CFull employment and stable prices.
- DFull employment alone.
59Why does an initial increase in aggregate expenditure of $l0 million lead to an increase in national income of more than $l0 million? Explain the economic process behind the multiplier as if to someone who never had the course.
- ABecause the mpc is greater than one.
- BThose employed because of the increased demand in turn increase their total consumer spending, which leads to higher national output and income, and further consumer spending.
- CBecause the mpc is a fraction so MULT = 1/(1-mpc) is greater than one.
- DWhen aggregate expenditure increases by $l0 million, national income will also only increase by $l0 million, because AE always equals Y.
60To realize a targeted real interest rate, bond-buyers who will become bond-holders have to [blank_start]lower[blank_end] their offer price to buy bonds, to realize a higher (nominal) interest rate, to cover inflation. The bond market falls when there is [blank_start]inflation[blank_end]. Higher inflation rate, higher nominal interest rate expected in bond market to cover inflation, reduced prices of bonds in the marketplace. Bond-holders [blank_start]hate[blank_end] this. It means their portfolio of bonds falls in value when there is [blank_start]inflation[blank_end].

61There is a conflict of interest between industry and finance over inflation: borrowers (industry, most households) do not mind a little [blank_start]inflation[blank_end], since it reduces the real carrying costs of debt. Lenders (finance, especially bond-holders), [blank_start]hate[blank_end] inflation for reducing their real interest earnings or even forcing them to choose between capital loss and illiquidity on bonds.
