Economics Review: Growth, Financial Systems, and Unemployment

This set of vocabulary flashcards covers essential concepts from the Solow growth model, financial intermediation, types of unemployment, inflation theories, and the foundations of business fluctuations as discussed in chapters 8 through 13.

Cutting-Edge Growth

Economic improvement specifically resulting from the development of novel concepts and new ideas.

Catching-Up Growth

Economic expansion primarily driven by the accumulation of physical and human capital.

Solow Growth Model Production Function

An economic equation expressing the relationship between total output ($Y$) and factors of production, represented as $Y = F(A, K, eL)$, where $A$ is ideas, $K$ is physical capital, and $eL$ is human capital and labor.

Marginal Product of Capital ($MPK$)

The specific increase in total output generated by adding a single unit of capital, which typically decreases as more capital is added to the economy.

Steady-State Level of Capital

The condition in which the capital stock remains constant because every unit of investment is used to replace capital that has depreciated.

Conditional Convergence

The pattern where poorer nations grow at a faster rate than wealthier nations when they have similar steady-state levels of output, leading to income levels meeting over time.

Time Preference

The human desire to obtain goods and services sooner rather than later, which influences individual savings rates and patience.

Market for Loanable Funds

The economic interaction where savers provide the supply of funds and borrowers generate the demand, determining the equilibrium interest rate.

Financial Intermediaries

Organizations such as banks, bond markets, and stock markets that bridge the gap between savers and borrowers by reducing transition costs and evaluating investments.

Crowding Out

The downward effect on private investment and consumption that occurs when government borrowing increases and raises interest rates.

Arbitrage

The process of trading equally risky assets to ensure that they earn similar returns throughout the financial market.

Leverage Ratio

A financial metric used to evaluate a firm's debt, calculated as the ratio of debt ($D$) to equity ($E$), or $\frac{D}{E}$.

Securitization

The process of bundling various loans, such as mortgages, together to be sold as financial assets to investors.

Unemployment Rate

The percentage of the total labor force that does not have a job but is actively seeking work, calculated as $\frac{\text{Unemployed}}{\text{Unemployed} + \text{Employed}} \times 100$.

Labor Force Participation Rate

The percentage of the adult, civilian, non-institutionalized population that is currently in the labor force, expressed as $\frac{\text{Labor Force}}{\text{Adult Population}} \times 100$.

Frictional Unemployment

Short-term joblessness caused by the standard difficulties and time required to match a willing worker with a suitable employer.

Structural Unemployment

Persistent and long-term joblessness resulting from large economic shocks or institutional features such as labor regulations that make hiring more difficult.

Cyclical Unemployment

Unemployment that fluctuates in direct correlation with the phases of the business cycle.

Quantity Theory of Money

The theory explaining the relationship between the money supply ($M$), velocity ($v$), price level ($P$), and real GDP ($Y_R$), represented by the equation $M \times v = P \times Y_R$.

Velocity of Money ($v$)

The average frequency with which a single unit of currency is spent on finalized goods and services within a given year.

Fisher Effect

The economic tendency for nominal interest rates to rise in alignment with the expected rate of inflation.

Aggregate Demand Curve

A curve illustrating all combinations of inflation and real growth that are consistent with a specific rate of spending growth.

Solow Growth Rate

The potential growth rate of an economy that occurs when prices are flexible and based on existing real factors of production.

Menu Costs

The specific expenditures a business faces when it chooses to change the prices of its products and services.
