📉 U.S. Economic Growth Slows Amid Tariff Pressures: A 2025 Outlook As 2025 unfolds, the U.S. economy is showing signs of strain amid a global slowdown and heightened trade barriers. Here's a detailed look at the latest forecasts and implications based on insights from the OECD, Federal Reserve, and key market indicators . 📊 1. U.S. Growth Forecast Downgraded by OECD The Organisation for Economic Co-operation and Development (OECD) has revised the U.S. GDP growth forecast for 2025 to 1.6% , down from 2.8% in 2024 . The forecast for 2026 remains muted at 1.5% , reflecting persistent uncertainty driven by: Elevated trade barriers Reduced consumer spending power Sluggish business investment 💸 2. Tariffs Fueling Inflation & Trade Costs The average U.S. tariff rate has climbed to 15.4% , the highest level since 1938 . These tariffs have raised import costs, which are now being passed on to consumers: Projected consumer price inflation is expected to rise to...

Cost function

-


A cost function is a mathematical representation of the relationship between the cost of production and the factors that influence it. It expresses the total cost (TC) as a function of the quantity of output (Q) and other relevant variables. The specific form of the cost function can vary depending on the industry, production process, and the nature of costs involved.

The general form of a cost function can be expressed as:

TC = f(Q, X₁, X₂, ..., Xâ‚™)

where:TC is the total cost of production,
Q is the quantity of output,
X₁, X₂, ..., Xâ‚™ are the other variables that impact production costs (such as labor, raw materials, energy, etc.).

The cost function can take different functional forms, including linear, quadratic, or more complex equations. The choice of the specific form depends on the characteristics of the production process and the behavior of costs.

For example, a simple linear cost function could be:

TC = a + bQ

where "a" represents the fixed costs (such as rent, insurance, etc.) and "b" represents the variable cost per unit of output (including costs like raw materials, direct labor, etc.).

More complex cost functions might include additional variables, such as economies of scale, production technology, or other cost drivers specific to the industry or firm.

It's important to note that the cost function is based on historical data and empirical observations, and it helps firms make informed decisions regarding production levels, pricing strategies, and profit optimization.


To determine the average fixed cost (AFC) and average variable cost (AVC) from a given cost function and level of output, follow these steps:

Understand the cost function: The cost function represents the relationship between the total cost and the level of output. It can be expressed as follows: Total Cost (TC) = Total Fixed Cost (TFC) + Total Variable Cost (TVC)


Calculate the AFC: AFC represents the fixed cost per unit of output and is obtained by dividing the total fixed cost by the quantity of output. AFC = TFC / Quantity of Output


Calculate the AVC: AVC represents the variable cost per unit of output and is obtained by dividing the total variable cost by the quantity of output. AVC = TVC / Quantity of Output

The law of diminishing returns states

-
What is t he law of diminishing returns ? The law of diminishing returns states that as additional units of a variable input are added to fixed inputs, the marginal product of the variable input declines after a certain point. This observation was first made by the British economist David Ricardo in the context of agriculture in nineteenth-century England, where successive doses of labor and capital yielded smaller increases in crop output.  Diminishing returns also apply to manufacturing when a firm starts to exceed the capacity of its existing plant. Example of crop yield for  t he law of diminishing Let's say a farmer has a fixed amount of land, let's say one acre, and they want to grow corn. They start by planting 100 seeds, and with the help of a fixed amount of fertilizer and water, they get a yield of 100 bushels of corn. If the farmer decides to increase the number of seeds planted to 200, they might see a corresponding increase in yield to, say, 180 bushels. However, ...

Operation Sindoor: Unfolding Economic and Geopolitical Ripples

-
Operation Sindoor, launched by India as a strategic military response to a terror attack in Pahalgam, has sparked a wide array of economic and geopolitical consequences. Its impact has been felt not only in South Asia but has also rippled across regions such as Turkey, highlighting the interlinked nature of global politics and economics. 🇮🇳 India’s Calculated Economic Strategy Despite the heightened military action, the Indian government has maintained that Operation Sindoor will not adversely affect the national economy . According to BJP spokesperson Gopal Krishna Agarwal, India’s trade ties with Pakistan were already negligible , minimizing any fallout. The operation was carefully executed to ensure domestic financial stability remained intact , underlining India’s focus on strategic precision and economic foresight. 🇵🇰 Pakistan Faces the Heat Prime Minister Narendra Modi delivered a clear warning: Pakistan would face severe economic repercussions for backing terrorist ele...

Elastic and inelastic demand

-
  Elastic and inelastic demand are two concepts used in economics to describe the responsiveness of demand for a product or service to changes in its price. Elastic demand refers to a situation where the quantity demanded of a product or service changes significantly in response to a change in its price. In other words, when the price of the product or service goes up, the quantity demanded falls significantly, and when the price goes down, the quantity demanded increases significantly. Elastic demand is characterized by a relatively flat demand curve. Examples of products with elastic demand include luxury goods, vacations, and restaurant meals. Inelastic demand, on the other hand, refers to a situation where the quantity demanded of a product or service changes relatively little in response to a change in its price. In other words, when the price of the product or service goes up, the quantity demanded falls only slightly, and when the price goes down, the quantity demanded incre...
