Q

Imperfect Competition

A

Price is a variable under the firms control and is a function of quantity (monopoly)
Price searcher firms
- priceis not fixed but varies depending on the quantity produced by the firm.
- This gives the firm pricing power , meaning it can influence the price by adjusting its output levels.
- Amonopolyis given as an example where a firm has significant control over pricing due to lack of competition.

TR = TC : Breakeven
TC > TR > TVC : continue in short run, shut down in long run
TR< TVC : shutdown in short and long run

Q

Business Cycles: Expansion

A

Expansion:
- Real GDP increases consistently
- Growth rate is above average
- Positive output gap
- Prices rise, interest rates start to increase to keep up with inflation
As economy nears peak - growth rates of spending, investment, employment may slow down but remain positive, inflation begins to rise
- Imports increase because there is a strong domestic economy

Q

Monetary Policy

A

Controlled by thecentral bank, focusing onmanaging money supply and credit.

set of actions undertaken by a central bank to manage the money supply and interest rates in an economy. Its main goal is to influence macroeconomic factors such as inflation, employment, and economic growth

price stability and economic growth

Primary Tools: Interest rates, open market operations, reserve requirements

Speed of implementation is faster than fiscal as central banks act independently

shorter lag time

Q

Fiscal Policy Tools

A

Spending tools:

Transfer payments: Redistributes income, such as unemployment benefits and social security. These payments do not count toward GDP.

Current Spending: Routine government expenses for goods and services

Capital Spending: Investment in infrastructure (e.g., roads, bridges, schools) to boost future economic productivity. - ‘Multiplier effect’ - Fiscal Multiplier - for every dollar spent, it will be multiplied up like a ripple effect in the economy and the benefit will be far larger than the actual spend itself.

Goals of Spending Tools:

  • Provide essential public services (e.g., defense).
  • Invest in infrastructure to support economic growth.
  • Directly support economic targets like reducing unemployment.
  • Ensure a minimum standard of living.
  • Subsidize R&D in areas aligned with long-term goals (e.g., green technology).

Q

Fiscal Multiplier

A

For every dollar spent in the economy, it will have an even higher impact than that 1 dollar; creates a “ripple effect”

Fiscal Multiplier = 1 / 1 - MPC (1-t)

Ex)
MPC = 0.8
t = 0.25
$100bn spending increase

1 / [1-0.8 (1-0.25)] x $100 = $250 Billion increase in consumption

Q

Crowding out

A

refers to the possibility that government borrowing causes interest rates to increase and private investment to decrease. If government debt is financing the growth of productive capital, this should increase future economic growth and tax receipts to repay the debt.

22
Q

Ricardian equivalence

A

is the theory that if government debt increases, private citizens will increase savings in anticipation of higher future taxes, and it is an argument against being concerned about the size of government debt and budget deficits

23
Q

  1. Regulating Money supply
  2. Setting interest rates
  3. Managing inflation and price stability
  4. Promoting employment
  5. Ensuring financial stability
  6. Managing exchange rates
  7. Banker to the government
  8. Lender of last resort
  9. Holder of gold and foreign currency reserves
24
Q

Tools of Monetary Policy

A
  1. Open market operations - Buying and selling government securities in the open market to influence liquidity and interest rates.
  2. Policy Interest Rates - - Adjusting benchmark rates (e.g., the discount rate or repo rate) to influence lending rates across the economy.
  3. Reserve Requirements:
    • Setting the minimum reserves that banks must hold, impacting their ability to lend.
  4. Quantitative Easing (QE) and Tightening (QT):
    • QE: Injecting liquidity into the economy by purchasing long-term securities.
  • QT: Removing liquidity by selling securities or allowing them to mature without reinvestment.
  1. Forward Guidance:
    • Communicating the expected path of future monetary policy to influence market expectations and economic behavior.
25
Goals of Monetary Policy
1. Price Stability: - Maintain low and stable inflation. - Prevent deflation (a general decline in prices). 2. Full Employment: - Strive for a low unemployment rate consistent with a healthy economy. 3. Economic Growth: - Create an environment conducive to sustainable long-term growth. 4. Stable Financial System: - Reduce risks of financial crises and ensure smooth functioning of markets. 5. Exchange Rate Stability (for some economies): - Avoid excessive volatility in currency values, especially in trade-dependent nations.
26
Central Bank Buying & Selling Securities
The buying and selling of securities (usually government bonds or Treasury securities) is one of the central bank's primary tools to control the money supply and influence the economy. This process is part of Open Market Operations (OMO) Buying Securities: - It injects money into the economy. - The sellers (banks, financial institutions, etc.) get cash in exchange for the bonds. - This increases the money supply, making borrowing cheaper (lower interest rates) and encouraging spending and investment. Selling Securities: - It pulls money out of the economy. - Buyers give up cash in exchange for the bonds. - This decreases the money supply, making borrowing more expensive (higher interest rates) and cooling down inflation or an overheating economy.
27
Quantitive Easing
QE is an expansionary monetary policy used when interest rates are already very low (or near zero) and further rate cuts are not possible or effective. The goal is to stimulate the economy by increasing liquidity. - **QE expands the central bank’s balance sheet**: - When the central bank buys securities, it records these as assets. - At the same time, the money it creates to buy them increases its liabilities (the reserves of commercial banks). Here’s how it works: 1. The central bank purchases long-term securities (like government bonds, mortgage-backed securities, etc.) from the open market. 2. This increases the reserves of commercial banks, giving them more cash to lend to businesses and consumers. 3. With more money circulating, interest rates fall, making borrowing cheaper. 4. Cheaper borrowing encourages businesses to invest and consumers to spend, boosting economic activity. **Example of QE in Action**: - After the 2008 financial crisis, the Federal Reserve undertook massive QE programs, purchasing trillions of dollars in Treasury bonds and mortgage-backed securities to stimulate the U.S. economy.
28
Quantative Tightening
**QT = Central Bank Selling Securities (or letting them mature)** QT is a contractionary monetary policy used when the economy is overheating, inflation is rising too quickly, or financial bubbles are forming. The goal is to reduce liquidity in the system. - **QT shrinks the central bank’s balance sheet**: - When the central bank sells securities or allows them to mature, both assets (securities) and liabilities (reserves) decrease. Here’s how it works: 1. The central bank sells securities back into the market or lets its bond holdings mature without reinvesting. 2. This removes cash from the banking system as banks and other institutions pay for the bonds. 3. With less money circulating, interest rates rise, making borrowing more expensive. 4. Higher borrowing costs slow down spending and investment, cooling inflation and economic activity. **Example of QT in Action**: - Starting in 2017, the Federal Reserve began shrinking its balance sheet by allowing bonds to mature without reinvesting the proceeds, signaling QT after years of QE.
29
When a central bank BUYS securities
- Bank reserves increase - Interbrank lending rates decrease - Short term and long term lending rates decrease - businesses increase investment - consumers increase durable goods purchases - domestic currency depreciates, exports increase
30
When a central bank DECREASES policy rate
- Market rates decrease - Lenders reduce short term and long term lending rates - Interbank lending rates decrease - Firms and individuas raise growth expectations
31
Central Bank Essental Qualities
1. Independence: The central bank should operate without political interference to focus solely on managing inflation, as political motivations may conflict with inflation control (e.g., boosting economic activity before elections). 2. Credibility: - The central bank must follow through on its policies and maintain consistency. - Credibility influences expectations; if markets trust the bank to keep inflation in check, this expectation alone helps stabilize prices. - A central bank must reliably follow through on its stated inflation targets to be taken seriously. If markets trust the bank’s commitment to a target (e.g., 3%), inflation expectations align with this rate, helping to anchor actual inflation at that level. 3. Transparency: - The central bank should clearly communicate its policy intentions, economic indicators, and decision rationale. - Transparency in inflation targets (usually 2-3%) and policy actions helps align market expectations with central bank goals. - By regularly disclosing economic assessments and reporting on inflation targets, a central bank strengthens its credibility. Transparency helps the market understand the factors influencing policy decisions, making policy changes easier to anticipate and enhancing the bank’s effectiveness in managing inflation. 4. Inflation Targeting: - Most central banks now target inflation directly, instead of focusing solely on interest rates. - When inflation is above the target, the bank will reduce money supply to control prices; when below, it may increase money supply to stimulate demand.
32
Liquidity Trap
- When people prefer holding cash over investing, even at low interest rates, monetary policy becomes ineffective in lowering rates further. This often occurs during deflation, when expansionary policies fail to stimulate growth. - Rates can’t go any lower - if they’re already at zero, cant go any more
33
Tight Monetary and Tight Fiscal Policy (slowing economy)
- Interest Rates: Higher. - Output: Likely lower, as both policies suppress spending. - Private and Public Sector Spending: Both are reduced, likely leading to a recessionary environment. - **Implications**: Used to address high inflation but risks economic contraction. - **Effect**: Decreased economic growth and spending. - **Interest Rates**: Higher, discouraging borrowing. - **Outcome**: Both private and public sectors shrink, reducing demand and GDP.
34
Easy Monetary and Easy Fiscal Policy (expanding economy
- **Interest Rates**: Lower. - **Output**: Likely higher, as low rates and increased government spending stimulate economic activity. - **Private and Public Sector Spending**: Both increase, which can lead to rapid economic growth but risks inflation if overused. - **Implications**: Often used during recessions to jumpstart economic activity. 1. - **Effect**: Strong economic growth. - **Interest Rates**: Lower, encouraging borrowing and spending. - **Outcome**: Both private and public sectors grow.
35
Tight Monetary and Easy Fiscal Policy
- Interest Rates: Higher. - Output: Higher, as government spending drives demand despite higher rates. - Private Sector Spending: Lower, as high interest rates discourage private borrowing. - Public Sector Spendin*: Higher, offsetting the private sector’s reduced spending. - Implications: Can help maintain control over inflation while still boosting growth through government spending. - Effect: Government spending drives demand, but borrowing costs are higher. - Interest Rates: Higher due to tight monetary policy. - Outcome: Government spending grows as a share of GDP, while higher rates may limit private sector growth.
36
Easy Monetary and Tight Fiscal Policy
- Interest Rates: Lower. - Output**: Variable, as outcomes depend on the balance between lower private borrowing costs and reduced government spending. - Private Sector Spending**: Higher, encouraged by low borrowing costs. - Public Sector Spending**: Lower due to fiscal constraints. - Implications**: Encourages private sector-led growth without increasing government debt, useful in economies aiming to reduce fiscal deficits. - Effect**: Lower interest rates stimulate private sector growth. - Interest Rates**: Lower due to increased money supply and less government borrowing. - Outcome**: Private sector expands, while government spending declines as a share of GDP.
37
Autarky
NON-cooperation and nationalism: goal of self reliance, producing domestically, low/no external trade or capital flows, state ownership of strategic industries eg) North Korea
38
Hegemony
Noncooperation and globalization: open to global trade, influence; state of control of key exports eg) USA & Russia Engages globally but with unilateral influence rather than cooperation
39
Multilateralism
Cooperation & globalization: integrated globally, many trading partners, rule standardization eg) Singapore, EU, Canada Engages in global trade and cooperation with multiple nations, sometimes regionally focused (e.g., EU).
40

43
Describe Geopolitical Risk
- Definition: The risk of events disrupting peaceful international relations, classified into three types: - Event Risk: Known timing but unknown outcomes (e.g., elections). - Exogenous Risk: Unexpected events (e.g., wars, uprisings). - Thematic Risk: Long-term trends with broad impact (e.g., migration, cyber risks). - Risk Classification by Velocity: - High Velocity: Immediate impact, e.g., black swan events like unexpected wars. - Medium Velocity: Gradual effect on specific sectors (e.g., industry regulations). - Low Velocity: Slow, long-term impacts, relevant to ESG factors.
44
Tariff
Tax imposed on imported goods collected by government - Increase the domestic price of imports, benefiting domestic producers and the government through tariff revenue but reducing consumer surplus. - Designed to domestic manufacturing industries - Increases the domestic supply while decreasing the quantity imported. - Tarifs on imported goods
45
Quota
Limitation on the quantity of good imported 2. - Set a limit on imports, raising domestic prices and benefiting domestic producers. If import licenses are not sold, **quota rents** accrue to foreign exporters, creating a larger welfare loss for the importing country. - Limit on the amount of goods imported - You can get import licenses
46
export Subsidy
Payments by governments to domestic exporters - Raise the price of goods in the exporting country, benefiting producers but reducing consumer surplus domestically. - Payments to domestic exporters by govt to encourage domestic exports - Helping econ growth and GDP - Exports are creating employment and econ growth, strengthen economy - Loans, cheap finance, assistance/help
