Q11
What baseline macroeconomic identity connects net domestic saving ($S$), private domestic investment ($I$), government expenditure ($G$), and tax revenue ($T$) in a closed economy?
$(I + S) \equiv (G + T)$
$(I - S) + (G - T) = 0$
$I imes S \equiv G imes T$
$S - I \equiv T + G$
Explanation
In a closed economy macro model, the financial balance requires that the private investment-saving gap equals the public budget deficit, expressed as $(I - S) + (G - T) = 0$.
Q12
What behavioral metric calculates the exact proportion of total current wealth assets that an individual chooses to hold in a highly liquid cash format?
Marginal efficiency of capital factor
Liquidity preference coefficient or asset ratio
Accelerator velocity parameter
Consumption distribution modulus
Explanation
The liquidity preference coefficient or cash asset ratio measures an individual's structural choice to hold wealth in cash rather than illiquid, income-yielding investment securities.
Q13
Which saving model incorporates an implicit 'bequest motive,' explaining why individuals accumulate substantial wealth asset portfolios that are never fully consumed during their biological lifespans?
The absolute lifecycle framework of Modigliani
The dynastic altruism model with an active bequest motive
The permanent income baseline of Friedman
The liquidity constraint tracking paradigm
Explanation
The Barro-Ricardo intergenerational altruism model (or dynastic life-cycle model) includes a bequest motive where individuals care about the utility of their descendants, shifting their saving behavior beyond their personal lifespans.
Q14
What economic index measures the structural rate at which an economy can replace physical capital decay with gross private domestic investment to protect its net wealth stock?
The incremental capital-output ratio (ICOR)
The net capital accumulation or net investment ratio
The marginal propensity to consume coefficient
The velocity of money asset circulation
Explanation
The net investment ratio tracks the proportion of gross capital investment directed toward expanding the capital stock after adjusting for capital consumption allowances (depreciation). This dictates net wealth accumulation rates.
Q15
Under the Ramsey-Cass-Koopmans optimal growth model, what parametric rule states that an economy achieves a steady-state level of capital wealth when the net saving rate balances the rate of population growth, depreciation, and technical progress?
The Phillips curve tracking envelope
The balanced-growth investment rule or capital deepening threshold
The Gossen saturation equilibrium path
The liquidity constraint interest ceiling
Explanation
The Solow-Solow-Solow-Swan or Ramsey steady-state balance occurs when savings exactly offset capital dilution from depreciation and population scaling, keeping capital per worker constant over time.
Q16
If a corporate entity retains its quarterly profit streams to fund research and development instead of distributing cash to stock owners, how is this internal allocation classified in financial flow analysis?
Autonomous household consumption spending
Corporate saving deployed as internal capital investment
A liquid portfolio currency optimization shift
An explicit public sector transfer payment flow
Explanation
Retained earnings spent on corporate R&D represent a direct transition of business savings into intellectual capital investment, aimed at expanding long-term non-tangible asset wealth.
Q17
What structural process defines 'capital deepening' within an economy's long-term wealth asset map?
The rapid print of liquid central bank cash paper
An increase in the total stock of physical capital per unit of labor input ($K/L$)
The conversion of fixed wealth portfolios into intermediate goods
A parallel rise in structural entry barriers to trade
Explanation
Capital deepening occurs when the stock of physical capital per worker increases over time ($K/L$), increasing labor productivity and shifting long-run output capabilities forward, separate from capital widening.
Q18
Which economic term captures the condition where an excess of savings relative to profitable domestic investment options drives real interest rates to extremely low or negative levels?
The liquidity trap loop
The global saving glut anomaly
The paradox of capital deepening
The accelerator deceleration matrix
Explanation
The global saving glut hypothesis suggests that an excess of global savings relative to domestic investment opportunities drives down global equilibrium real interest rates.
Q19
Which type of investment calculation evaluates the addition to the real physical stock of capital after deducting the capital consumption allowance from gross investment?
Circulating asset turnover
Net private domestic physical investment
Autonomous monetary liquidity tracking
Sunk accounting capital reserve
Explanation
Net investment is calculated as Gross Investment minus Depreciation (capital consumption allowance). It represents the true expansion of an economy's physical capital wealth stock.
Q20
If an increase in private savings is accompanied by a persistent collapse in consumer business investment because firms anticipate a drop in future demand, how is this macroeconomic gridlock classified?
The monetary crowding out effect
An underconsumption gridlock or investment coordinate failure
An automated ricardian stationary expansion
A pure hyper-velocity cash injection
Explanation
Under the underconsumption or paradox of thrift paradigm, a surge in saving cuts aggregate demand. If firms do not respond by investing due to weak sales, national income contracts, highlighting how saving can fail to become physical investment.
