5 November 2026Trade and honest dealing in the legacy of Imam al-Bukhari
The famous collection of the Bukhara scholar Imam al-Bukhari contains a separate book devoted to buying and selling. We take an impartial look at how its idea of truthfulness and not concealing defects is in harmony with today's market and accounting discipline.
5 November 2026MONIAC: how was the economy explained with water pipes?
In 1949 in London a student demonstrated the economy with a machine made of water, tanks and pipes. Short key points and an example with a simple calculation about this "water computer", which made the flow of money visible to the eye.
7 November 2026François Quesnay and the "Economic Table" (1758): how did a court physician fit the economy into a single diagram?

The name "Silk Road" for the route caravans travelled for centuries appeared much later, in 19th-century works in German. Today parts of this route stand on the UNESCO World Heritage List as "corridors": the Chang'an–Tianshan Corridor in 2014 and the Zarafshan–Karakum Corridor in 2023. Short theses and a calculation of how prices grow in trade with many intermediaries.
10 November 2026Articles and briefs
All →Who is an entrepreneur and what is an enterprise?
The eleventh Basics lesson: when Munisa, who sews dresses at home, becomes an entrepreneur, what an enterprise is, and why business money must not get mixed up with family money. With a simple calculation for one month.
11 November 2026Engel's law: if a family's income doubles, does its spending on food double too?
A family with a monthly income of 6 million soum spends half of it on food, while a family with 24 million soum spends only a quarter. The amount spent on food rises, but more slowly than income. This is Engel's law, observed in the 19th century. Its cause, how it is measured, its limitations and a practical conclusion for a neighbourhood shop owner.
11 November 2026What are ownership and property?
The seventh Basics lesson: which things in a seamstress's home are hers, and which she has only taken to use. We make a list of her property and calculate its value.
10 November 2026The seller pays the levy, but who bears its burden? Elasticity of demand and the question of who really pays
Suppose a fixed levy of 3 000 soums per box is introduced. For one product the price rises by only 1 000 soums and the seller bears the other 2 000 soums; for another the price goes up by 2 400 soums. Who pays the difference is decided not by what the law says, but by how sensitive buyers and sellers are to price. A calculation using two markets.
10 November 2026Goods and services: what is the difference?
The fourth Basics lesson: the difference between a thing you can hold and take home and work that someone does for you. Shown with a barber, a baker and a cafe.
9 November 2026What is a price and how does it appear?
The third Basics lesson: what is hidden inside the price of one loaf, how a baker works out his price, and why tomatoes get more expensive in winter. With simple examples.
9 November 2026What is a market?
The second Basics lesson: is a market only stalls and counters, who meets there, and why three bakers on one street are good for the buyer. In the simplest words.
9 November 2026Make it ourselves or buy it ready-made: which costs really matter for the decision?
The bread a restaurant bakes itself costs 3 383 soum at full cost, while ready-made bread costs 3 200 soum. So is buying cheaper? No: tandoor depreciation and the share of rent remain whatever the decision. If only the costs that differ are counted, baking it ourselves saves 900 thousand soum a month. But if the freed-up space can earn income, the answer changes again.
9 November 2026Break-even point: how many cups a day must a café sell to cover its costs?
If 60 cups of coffee are sold every day, the café makes neither a profit nor a loss. Why, with average sales of 85 cups, is Monday still a loss? Contribution margin, the margin of safety, what happens if rent goes up or milk gets dearer, and operating leverage on the example of one café.
8 November 2026Does a discount increase revenue? Calculating the price elasticity of demand and checking profit
A coffee shop offered a 15% discount on coffee. We calculate elasticity in two scenarios, show when revenue rises and when it falls, and check why profit may fall even if revenue rises.
7 November 2026Economies of scale: why does the cost per unit fall when more is produced, and when does it stop?
When more bread is baked, the rent and equipment cost per loaf decreases. But beyond a certain point a new tandoor, and a new cost, is needed. A calculation using a bakery as an example.
6 November 2026Should you regret the money spent on old equipment? Sunk costs and the right decision
"I paid 30 mln for the oven, I can't just throw it away now": a familiar thought? In economics such spending is called a sunk cost, and it should not affect the decision. Using a café as an example, we compare two options.
