Study Notes

Finance and Growth

Theoretical and empirical definitions are presented in the study.
Nominal GDP vs. Real GDP: Nominal GDP uses current prices, while real GDP uses constant prices (from a base year). Differences in these measurements are important.
GDP is different from GDP per capita: GDP per capita is GDP divided by the population size.
Purchasing Power Parity (PPP): PPP is needed to accurately compare growth rates across countries, as exchange rates can distort comparisons. PPP accounts for differences in purchasing power between countries
Limitations of PPP: Transaction costs (e.g. transportation, tariffs), differences in goods baskets, less integration of commodity markets than capital markets, and differences in productivity can impact PPP calculations.
Example of Calculating PPP: Calculation example given using GDP in US dollars/Rupees and exchange rate, showing how PPP exchange rate is calculated.
GDP (PPP) is used to show differences in GDP using PPP exchange rates.
Solow's Model: Solow was a key scholar in formalizing the growth model.
Solow's Model focuses on capital stocks, Investment, depreciation, steady state level of capital and growth.
Solow-Swan Model: If parameters like technological progress saving rates remain constant, all countries converge to the same capital and wages per worker.
Solow Model Implications: Poorer economies should grow faster than rich ones (conditional convergence) - this isn't proven by empirical evidence
Conditional Convergence: Initial conditions matter for growth rates and countries that have the largest deviation from the steady state tend to grow faster
B-convergence: Convergence is when the country with a lower initial income grows faster than countries with higher income.

Growth Accounting

Growth accounting is used to determine the factors contributing to economic growth.
Constant returns to scale implies that increasing input factors equally leads to proportionally larger output. Decreasing returns to scale means that increasing input factors doesn't lead to a proportional increase in output.
Marginal Product of Labor (MPL) and Marginal Product of Capital (MPK): These measures are used to quantify the increase in output due to increased capital or labor.
Total Return of Capital: This is part of the capital's income.
Solow Residual (TFP): A measure of productivity/TFP accounting for efficiency of the actual state of technology improvements.
