Final answer:
Savings and investment flows at full employment may not always be equal due to various economic influences. President Obama was concerned about the economy because of the 2008 financial crisis and its impact. Economic equilibrium occurs when supply equals demand, and the GDP gap is indicative of either a recessionary or inflationary gap.
Step-by-step explanation:
Savings and Investment Flows at Full Employment
Investment and savings flows may not always be equal at full employment due to factors like expected returns on investments, interest rates, and economic policies, which can influence the levels of saving and investment separately. Also, in an open economy, these flows can be supplemented or drained by international capital flows.
President Obama's Concern About the Economy
At the outset of his presidency, President Obama was concerned about the economy due to the severe financial crisis of 2008, which led to significant job losses, failures of major financial institutions, and a deep recession. The economic stability and recovery were critical challenges he needed to address.
Economic Equilibrium and GDP Gap
Economic equilibrium occurs when aggregate supply equals aggregate demand. The GDP gap can be estimated by comparing actual GDP to potential GDP, which represents full employment. If actual GDP is lower than potential, it indicates a recessionary gap; if higher, it indicates an inflationary gap.
Government Budget Deficits and Macroeconomy
Increased government budget deficits can affect the macroeconomy in three ways:
Reducing national saving
Increasing interest rates
Affecting exchange rates and trade balances
Larger budget deficits would generally be expected to decrease private sector investment in physical capital by either 'crowding out' private investment through higher interest rates or by using up financial resources that might otherwise have been available for private investment.
Ricardian Equivalence
The theory of Ricardian equivalence suggests that when a government increases debt to fund spending without changing taxes, rational consumers anticipate future taxes and save accordingly, which neutralizes the fiscal stimulus.
Fiscal Policies for Economic Growth
Fiscal policies that encourage economic growth include tax incentives for investment, government spending on infrastructure, and policies designed to increase human capital and technological advancement.
