Expected Value of Perfect Information (EVPI)

Expected Value of Perfect Information = Expected payoff with perfect information – Expected payoff without perfect information.

Expected payoff with Perfect Information: Create a new row in the payoff table which lists the best payoff for each state of nature. Determine the expected payoff of this row to obtain the expected payoff with perfect information.

Expected payoff without Perfect Information: The expected payoff of the best decision when you use the expected value approach (choose the alternative with the highest expected payoff).

Posterior Probabilities and EVSI

Posterior probabilities arise when you obtain additional testing or survey data (at some expense) to improve prior state probabilities.... Continue reading "EVPI and EVSI: Expected Value, Utility & Decision Analysis" »

Timeliness Principle

The Timeliness principle in accounting refers to the need for accounting information to be presented to users in time to fulfill their decision-making needs.

• Example: Users of accounting information must be provided financial statements on a timely basis to ensure that their financial decisions are based on up-to-date information. This can be achieved by reporting the financial performance of companies with sufficient regularity (e.g., quarterly, half-yearly, or annually) depending on the size and complexity of the business operations. Unreasonable delay in reporting accounting information to users must also be avoided.

Prudence Principle

Prudence requires that accountants should exercise a degree of caution in the adoption... Continue reading "Essential Accounting Principles" »

Chapter 4: The Federal Reserve's Responsibilities and Operations

Three Main Responsibilities of the Federal Reserve

1. Achieve full employment
2. Maintain price stability
3. Maximize economic growth

The Federal Reserve conducts the national monetary policy to achieve these goals.

Open Market Operations

Responsibilities:

• Control the money supply (MS)
• Set targets for MS growth and interest rate levels
• Influence the MS by buying or selling government securities (debt securities, Treasuries)

The Trading Desk

What they do: Purchase or sale of Treasuries

Impact on the economy:

• Money Supply: Purchasing government securities increases the money supply, while selling them decreases it.
• Interest Rates: An increased money supply puts downward pressure on interest rates, while

Understanding Income Inequality

Definition of Income Inequality

Income inequality refers to the phenomenon where households earn different shares of income within an economy.

Key Characteristics of Income Distribution

• Income is typically unequally distributed within economies.
• Inequality can provide incentives and rewards for productivity and innovation.

Measuring Income Inequality

The Lorenz Curve

The Lorenz curve illustrates the proportion of a nation’s income earned by a given percentage of the population. It typically lies below the line of complete equality because, for instance, the poorest 20% of the population will own less than 20% of the national income. The more curved the line, the greater the degree of inequality.

The Gini Coefficient

The... Continue reading "Income Inequality: Policies, Measurement, and Economic Impact" »

Why Currency Exchange Rates Change

If our currency is demanded (for example, because our products are demanded), the price of our currency would increase unless we increase the money supply. Conversely, if, for example, people hold assets in our currency but want to sell them, this would lead to depreciation.

Interest rate is the price of our money, because we sell bonds that yield a certain benefit. If we increase the interest rate, we make the bond more attractive. People would invest money in these bonds, and less money would circulate in the economy.

This internal use of interest rates to control inflation also has external consequences. High interest rates make bonds more attractive to foreign investors who would want to buy Euros (or the... Continue reading "Factors Affecting Currency Exchange Rates" »

Types of Market Research Information

• Demographics: Knowing more about the characteristics of your market.
• Economic information
• Social and cultural influences
• Political and legal information and influences
• Consumer buying habits and behavior
• Market size and potential for growth
• Competitor information
• Resources, support, and costs

Psychic Distance

Psychic distance refers to the difference in socio-cultural factors between countries. It is arguably easier to enter a market if the distance is smaller. Therefore, businesses should choose countries that have similarities to their domestic market.

Political and Legal Influences

Two current examples include Brexit and Donald Trump as US President. The importance of these factors lies in their influence on the... Continue reading "Key Factors in International Market Research Analysis" »

Money Demand and Its Determinants

Money demand depends on the price level and the volume of transactions, which is defined as the number of goods and services transacted using money in one year.

Money demand can be represented as: P × T, where T = volume of transactions and P = average price level.

When the money market is in equilibrium, Md = Ms (Money Demand = Money Supply).

Formula: P = (V / T) × M

Assumptions:

1. This theory applies to short-run changes.
2. There is full employment in the economy.
3. The velocity of money and the volume of transactions remain constant.
4. The amount of barter trade remains constant.
5. M, V, and T change independently.

Changes in Velocity of Money (VOM):

• VOM increases: prices decrease = Deflation
• VOM decreases: prices increase =

Key Financial Ratios and Formulas

Understanding key financial ratios is crucial for assessing a company's performance and financial health. Below are common ratios and their formulas:

Accounts Receivable Turnover Ratio

Accounts Receivable Turnover = Sales & Service Revenue / Accounts Receivable Balance

Accounts Receivable Turnover in Days

Accounts Receivable Turnover in Days = 365 / Accounts Receivable Turnover

Inventory Turnover Ratio

Inventory Turnover = Cost of Goods Sold (CGS) / Inventory Balance

Inventory Turnover in Days

Inventory Turnover in Days = 365 / Inventory Turnover

Current Ratio

Current Ratio = Current Assets (CA) / Current Liabilities (CL)

Quick Ratio (Acid-Test Ratio)

Quick Ratio = (Current Assets - Inventory - Prepaid Expenses) / Current

Convergence Criteria (Maastricht Criteria)

Price Stability (Inflation)

Price stability — Inflation: The inflation rate of a given Member State must not exceed by more than 1.5 percentage points the average inflation rate of the three best-performing Member States in terms of price stability during the year preceding the examination of the situation in that Member State.

Government Finances: Deficit and Debt

Public deficit: When drawing up its annual recommendation to the Council of Finance Ministers, the Commission examines compliance with budgetary discipline based on two criteria.

• Annual government deficit: The ratio of annual deficit to GDP must not exceed 3% at the end of the preceding fiscal year. If this is not the case, the ratio must have
