Finance, Économie et Culture Générale

Concepts of Finance and Financial Markets

In the realm of finance, assets are categorized into two primary types of titles: an action is defined as a title of co-ownership within a company, whereas an obligation is a title of debt held against an entity. The price of an action at any specific moment is referred to as its market rate or cours. When evaluating the total value of a company’s shares, the term capitalisation boursière ($CB$) is utilized. For valuation purposes, analysts often look at the PER (Price-to-Earnings Ratio), which represents the rapport between cost and benefits. These markets are heavily influenced by the interest rate, denoted as $r$, which is metaphorically described as the rent or loyer of money. The quantity of money currently in circulation within an economy is known as the money supply or masse monétaire.

Investment vehicles include Sicavs, which are investment funds, and Trackers (also known as ETFs), which are titles designed to replicate the performance of a specific index. An investor's collective holdings of various titles are referred to as a portefeuille. Markets themselves exhibit different behaviors: a bear market signifies a downward trend, while a bull market indicates an upward trend. Extreme market reactions are termed as overshooting. There are also specific styles of stocks: an action value refers to a stable and undervalued stock, while an action growth belongs to a company experiencing rapid expansion. Market cycles can include speculative bubbles, which are characterized by a spectacular rise followed by a collapse, or a krach, which is a generalized collapse of prices. During times of instability, investors may engage in a flight to quality, selling growth actions to purchase value actions.

Derivative transactions include calls, which are options to buy, and puts, which are options to sell. A future is a transaction where terms are determined in the present for execution at a later date. Personal financial tools include assurance vie (pension savings) and assurance décès (insurance to compensate a third party in the case of an unforeseen death). The ease with which an asset can be converted into cash is its liquidité. Bank-specific debt titles include the bon de caisse, while the state issues a bon d’État. Savings can also be placed in a compte à terme, where the money remains blocked for a certain duration.

Investment Strategies and Market Indicators

Investment strategies are often divided into two categories: aggressive placements involve investing in stocks (actions), while defensive placements focus on bonds (obligations). The duration for which an investment is held is the horizon de placement. To measure the market, indices are used, representing a weighted average of share values. Key global indices include the Dow Jones 30 in New York, the Bel 20 in Brussels, the Nikkei in Tokyo, and the Cac 40 in Paris. Every stock is identified by a specific abbreviation called a ticker.

Professional roles in this sector include the trader, who negotiates titles, and the financial analyst, who specializes in company valuation. Taxation on capital income is managed through the withholding tax known as the précompte mobilier, though certain cases may grant an exonération (exemption from payment). In corporate finance, a crédit d'investissement is a long-term bank credit used for acquiring fixed assets. The total resources available to a company are called its financement. Additionally, leasing is a long-term rental arrangement that includes an option to purchase the asset.

General Economics and Macroeconomic Policy

The fundamental measure of national production is the GDP ($PIB$), defined as the total value of goods produced within a country over one year. An increase in this metric is called growth (croissance), while persistent rises in general price levels are termed inflation. Sustainable development refers to growth that respects the environment. Production requires specific inputs known as factors of production, namely labor and capital. Efficiency is measured by productivity, which is the production output per hour of work. Companies may experience economies of scale (économie d’échelle) when their average costs decrease as production quantity increases.

Economic theories describe utility as the level of economic satisfaction derived by a consumer. An externality occurs when an economic agent's actions impact others. The general economic situation at a given moment is the conjoncture. Downturns are classified by duration: a recession is a decrease in GDP over a short period of $1$ to $2$ years, whereas a depression is a long-term decrease in GDP. A consumer's ability to purchase goods is their purchasing power, calculated as $Y / \text{inflation}$. To protect this, some systems use wage indexation, increasing salaries at the same rate as inflation.

Governments manage the economy through two main types of policy. Fiscal or budgetary policy can be expansionary, increasing the budget deficit to stimulate growth, or restrictive, decreasing the deficit to lower inflation and public debt. Monetary policy, managed by central banks, can be restrictive (increasing the interest rate, $r$, to lower inflation) or accommodating (decreasing the interest rate to boost growth). Factors affecting the economic system are classified as exogène (external to the system) or endogène (internal to the system).

Corporate Structure, Operations, and Competition

A company or entreprise is an organization that produces goods. Its total sales volume is the turnover or chiffre d’affaires ($CA$). The financial result ($R$) is either a profit or a loss, and the margin is calculated as the ratio $R / CA$. A company’s market share (part de marché) is defined by the formula $CA_{\text{entreprise}} / CA_{\text{secteur}}$. Growth strategies often involve diversification, where new products are launched. The shared values and behaviors of workers within a company constitute its culture d’entreprise. When a company reorganizes for efficiency, often resulting in layoffs, it is called a restructuration. The ability to face competition is known as compétitivité. Gains in efficiency resulting from a merger are called synergy.

Corporate acquisitions take two forms: an OPA (acquisition using cash/species) and an OPE (acquisition through the exchange of actions). Structural changes include cession (the act of ceding/yielding), cessation (the act of ceasing/stopping), and scission (the act of splitting). A session refers to an examination period. Companies often use brainstorming to generate ideas. Early-stage funding can come from a business angel (an investor specialized in new ventures) or family money.

Market Mechanisms and International Trade

Markets are defined as the meeting point of supply ($O$), the goods companies wish to sell, and demand ($D$), the goods households wish to purchase. The price where $O = D$ is the equilibrium price. The consumer surplus (surplus du consommateur) is the difference between the psychological price (the maximum a consumer is willing to pay) and the actual equilibrium price. Market structures are defined by the number of sellers: a monopoly has $1$ seller, a duopoly has $2$, an oligopoly has between $3$ and $6$, monopolistic competition has $7$ to $20$, and perfect competition involves more than $20$ sellers.

International trade consists of exporting ($X$) goods abroad and importing ($M$) goods from abroad. The trade balance is calculated as $X - M$. A specific tool for estimating local price levels is the Big Mac Index. Industry concentration occurs when the number of companies decreases due to mergers. This can be vertical concentration (merging with clients or suppliers) or horizontal concentration (merging with direct competitors).

Human Sciences, Biology, and Psychological Factors

The human experience within economic and social systems is influenced by the unconscious (inconscient), which consists of thoughts and impulses outside of conscious awareness. Biological factors include several key hormones: Oxytocin (affection and attachment), Serotonin (happiness), Dopamine (pleasure), Cortisol (stress), and Insulin (which decreases glycemia, the level of sugar in the blood). Health metrics include the BMI (IMC), calculated as $\text{weight} / \text{height}^2$. Specialists in these fields include endocrinologists (hormones) and neurologists (nervous system).

The brain functions in layers: the cortex is dedicated to reflection, the limbic system to emotions, and the reptilian brain to instinct and reflexes. Human behavioral traits include inclination, a pronounced taste for something, and rhetoric, the art of discourse.

Environment, Technology, and Industry

Environmental impact is measured by the ecological footprint. Land measurement uses the hectare, which is a surface area of $10,000\,m^2$. Factors related to land and territory are termed foncier. Communication networks and facilities are known as infrastructure. The term to emerge (émerger) refers to coming out of the water. Technological infrastructure includes data centers (sets of servers) and cloud computing (remote data storage and processing). Modern devices rely on semiconductors, which are microprocessor components. The process of becoming technologically outdated is known as obsolescence.

Industrial and agricultural terms include roasting (torréfaction, used for coffee), the chaebol (South Korean conglomerates), the miller (meunier, who operates a mill), and fodder (fourrage, which is food for livestock).

History and Economic Thought

Economic history is marked by three primary industrial revolutions: RI 1 (starting in $1780$, characterized by steel, trains, steam engines, and coal), RI 2 (starting in $1880$, characterized by electricity, automobiles, airplanes, and chemistry), and RI 3 (starting in $1950$, characterized by electronics, IT, and nuclear power).

Influential thinkers include Xenophon (Antique Greek historian), Adam Smith (18th-century Scot, theorist of market and competition), David Ricardo (18th-century English, theorist of international trade), and Karl Marx (19th-century German, theorist of class struggle). Subsequent 20th-century theorists include John Maynard Keynes (demand-focused), Milton Friedman (supply-focused), and Friedrich Hayek (economic liberty). The philosopher Montesquieu established the principle of the separation of powers, dividing government into legislative, executive, and judicial branches.

Societies have transitioned from traditional societies (based on custom and religion) to modern societies (based on progress, rationality, and democratic institutions). This shift was propelled by the Age of Enlightenment in the 18th century. In modern politics, the Treaty of Rome in $1957$ instituted the CEE. Major international organizations include the DGCCRF (EU consumer protection), the International Monetary Fund (FMI, aiding over-indebted countries), the World Bank (investing in development), the Federal Reserve (Fed, the US central bank), and the BCE (European Central Bank).

Global Currencies and Descriptive Expressions

International trade utilizes several key currencies: the Euro (EUR), US Dollar (USD), Japanese Yen (JPY), British Pound (GBP), Swiss Franc (CHF), Canadian Dollar (CAD), Danish Krone (DKK), Swedish Krona (SEK), and South African Rand (ZAR).

Various terminal concepts define social and economic interactions: antagonism (rivalry), pragmatic (focused only on results), and the Latin phrase hic et nunc (here and now). A boycott is a politically motivated refusal to buy. Terms describing strong reactions include honni (hated), allégrement (joyfully), and polemic (a violent and sterile debate). A complex, multi-faceted problem is compared to the hydra, a mythological monster. Failure causing disappointment is a déboire, and chance is referred to as an aléa. Excess is termed pléthore, while a plot is an intrigue. Something very important is crucial, and someone passionate is féru. Finally, a self-fulfilling prophecy (prophétie autoréalisante) occurs when a market rises simply because participants believe it will.
