+# Financial Crysis of 2007-2009
+
+## Summary
+
+The Financial Crisis of 2007-2009 was primarily triggered by the collapse of the U.S. housing market, exacerbated by complex financial instruments such as Mortgage-Backed Securities (MBS) and Credit Default Swaps (CDS). The crisis began in the housing sector but quickly spread to the broader financial system, ultimately requiring government intervention to prevent a complete economic meltdown.

+
+## Definitions and Important Concepts
+
+- MBS (Mortgage-Backed Securities): Investments consisting of a bundle of home loans and other real estate debt bought from the banks that issued them.
+- CDS (Credit Default Swaps): Financial derivatives that allow investors to swap or offset their credit risk with that of another investor.
+- LTV (Loan-to-Value) ratio: An assessment of lending risk that financial institutions examine before approving a mortgage.
+- Subprime Loans: Loans made to borrowers with poor credit histories, often with higher interest rates.
+- Tranches: Portions of a pooled collection of securities, usually debt instruments, that are split up by risk or other characteristics.
+- Credit Risk: The risk of loss resulting from a borrower's failure to repay a loan or meet contractual obligations.
+
+## Financial Theories/Models
+
+- Securitization: The process of pooling various types of debt instruments and selling them as securities to investors.
+- Risk Assessment Models: Tools used by financial institutions to evaluate the creditworthiness of borrowers and the risk of default.
+
+## Market Applications
+
+1. Housing Market:
+    - Low interest rates and relaxed lending standards led to a housing boom.
+    - Increased use of subprime mortgages with high LTV ratios.
+    - Rising home prices created a speculative bubble.
+2. Financial Market:
+    - Banks created and sold MBS, transferring the risk of subprime mortgages to investors.
+    - CDS were used to insure against potential defaults, creating a false sense of security.
+    - When housing prices began to fall, the value of MBS plummeted, causing significant losses for investors and financial institutions.
+
+## Case Studies or Examples
+
+1. Lehman Brothers Collapse: The failure of this major investment bank due to its exposure to subprime mortgages and MBS.
+2. AIG Bailout: The government rescue of AIG, which had sold massive amounts of CDS and faced bankruptcy when required to pay out.
+
+## Risk Considerations
+
+- Underestimation of systemic risk in the housing market.
+- Over-reliance on complex financial instruments without fully understanding their risks.
+- Inadequate regulation of the shadow banking system.
+- Misalignment of incentives in the mortgage origination and securitization process.
+
+## Key Takeaways
+
+1. The interconnectedness of the housing market and the financial sector through MBS and CDS amplified the crisis.
+2. High LTV ratios and subprime lending practices increased overall credit risk in the system.
+3. The crisis spread from the housing market to the broader financial sector, necessitating government intervention.
+4. The event highlighted the need for better risk management and financial regulation.
+
+## Questions for Analysis
+
+1. How did the misuse of financial instruments like MBS and CDS contribute to the severity of the crisis?
+2. What role did credit rating agencies play in the lead-up to the financial crisis?
+3. How have regulatory frameworks changed since the crisis to prevent similar events in the future?

+# Financial decision making and the law of one price
+
+## Summary
+
+This note explores the fundamental principles of financial decision making, focusing on the law of one price and related concepts such as time value of money, arbitrage, and net present value (NPV). These principles form the foundation for understanding financial markets and making informed investment decisions.
+
+## Definitions and Important Concepts
+
+- Common Unit: A standardized measure used to compare different financial assets or investments.
+- Arbitrage: The practice of taking advantage of a price difference between two or more markets, striking a combination of matching deals that capitalize upon the imbalance.
+- NPV (Net Present Value): A method used to determine the current value of all future cash flows generated by a project, including the initial capital investment.
+- Law of One Price: The economic theory that the price of identical goods or assets should be the same in different markets, assuming no trade restrictions and negligible transaction costs.
+
+## Financial Theories/Models
+
+1. Time Value of Money: The concept that money available now is worth more than the same amount in the future due to its potential earning capacity.
+2. Efficient Market Hypothesis: The theory that asset prices fully reflect all available information, making it impossible to consistently "beat the market."
+3. Capital Asset Pricing Model (CAPM): A model that describes the relationship between systematic risk and expected return for assets.
+
+## Formulas and Calculations
+
+- Net Present Value (NPV): $$NPV = \sum_{t=0}^{n} \frac{CF_t}{(1+r)^t} - I_0$$ Where:
+    - $CF_t$ is the cash flow at time $t$
+    - $r$ is the discount rate
+    - $I_0$ is the initial investment
+    - $n$ is the number of periods
+
+**Example:** A company is considering a project with an initial investment of $100,000. The project is expected to generate cash flows of $30,000 per year for 5 years. The company's cost of capital (discount rate) is 10%. Should the company pursue this project?
+
+Let's calculate:
+
+- $I_0$ = $100,000
+- $CF_t$ = $30,000 for each year
+- $r$ = 10% = 0.10
+- $n = 5$ years
+
+$$NPV = \frac{30,000}{(1+0.10)^1} + \frac{30,000}{(1+0.10)^2} + \frac{30,000}{(1+0.10)^3} + \frac{30,000}{(1+0.10)^4} + \frac{30,000}{(1+0.10)^5} - 100,000$$
+$$NPV = 27,272.73 + 24,793.39 + 22,539.45 + 20,490.41 + 18,627.64 - 100,000$$
+
+$$NPV = 113,723.62 - 100,000 = $13,723.62$$
+
+The NPV is positive, so the company should pursue this project.
+___
+- Future Value: $$FV = PV \times (1 + r)^n$$ Where:
+    - $FV$ is future value
+    - $PV$ is present value
+    - $r$ is interest rate
+    - $n$ is number of periods
+
+**Example:** You invest $5,000 in a savings account that offers 3% interest per year. How much will you have after 10 years?
+
+- $PV$ = $5,000
+- $r$ = 3% = 0.03
+- $n = 10$ years
+
+$$FV = 5,000 \times (1 + 0.03)^{10}$$ $$FV = 5,000 \times 1.3439$$ $$FV = $6,719.58$$
+
+After 10 years, your investment will grow to $6,719.58.
+___
+- Present Value: $$PV = \frac{FV}{(1 + r)^n}$$
+	Where
+	- PV = Present Value
+	- FV = Future Value
+	- r = Interest rate (or discount rate) per period
+	- n = Number of periods
+
+## Market Applications
+
+1. Investment Decision Making: Using NPV to evaluate and compare different investment opportunities.
+2. Pricing of Financial Instruments: Applying the law of one price to ensure consistent pricing across markets.
+3. Risk Management: Utilizing arbitrage principles to hedge against market risks.
+4. Corporate Finance: Making capital budgeting decisions based on NPV and other time value of money concepts.
+
+**Example:** You want to have $50,000 for a down payment on a house in 5 years. If you can earn 4% interest per year on your savings, how much do you need to invest today?
+
+- $FV = $50,000
+- $r = 4% = 0.04
+- $n = 5$ years
+
+$$PV = \frac{50,000}{(1 + 0.04)^5}$$ $$PV = \frac{50,000}{1.2166529}$$ $$PV = $41,098.97$$
+
+You need to invest $41,098.97 today to have $50,000 in 5 years, assuming a 4% annual interest rate.
+## Case Studies or Examples
+
+1. Currency Arbitrage: Exploiting price discrepancies in foreign exchange markets.
+2. Merger Arbitrage: Taking advantage of price differences between a company's stock price and the offered acquisition price.
+3. NPV in Project Evaluation: A company using NPV to decide between two competing investment projects.
+
+## Risk Considerations
+
+- Market Inefficiencies: Temporary violations of the law of one price due to market frictions or information asymmetries.
+- Transaction Costs: The impact of fees and taxes on the profitability of arbitrage opportunities.
+- Regulatory Risks: Changes in laws or regulations that may affect arbitrage opportunities or investment valuations.
+
+## Questions for Analysis
+
+1. How does the concept of time value of money influence long-term investment strategies?
+2. In what situations might the law of one price not hold, and what are the implications for financial markets?
+3. How can companies use NPV analysis to make better capital allocation decisions?
