This document discusses international trade and comparative advantage. It provides an example comparing India and France's production of cloth and cheese. If they specialize and trade based on their comparative advantages, total production increases from 500 to 800 units. A similar example compares US and Japanese production of computers and wheat. Without trade, total consumption is 3470 units, but with trade based on comparative advantages, total consumption increases to 3800 units, making both countries better off. The document notes some limitations of comparative advantage analysis in the real world.
That is the part of my book on international business. this is very informative. i complete this book in 1 year. that is very useful for master students.
A ppt on David Ricardo's Comparative advantage with examples taking Portugal and England. The PPT aims to reveal Ricardo justification for doing trade even though Portugal has complete advantage in the production of cloth and wine

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

Two countries: India and France
Two goods: cloth and cheese
We will look at how much of both goods
each country produces and consumes:
1.) If the country chooses to be self-sufficient 自给 and does not
trade.
2.) If it trades with the other country.

28. Consumption With and Without Trade
Without trade
India consumers get 200 units
of cloth and 50 units of
cheese.
France consumers get 50 units
of cloth and 200 units of cheese.
Total of 500 units produced
31. Consumption With and Without Trade
India makes 400 units of
cloth and 0 units of cheese.
France makes 0 units of cloth
and 400 units of cheese.
With trade
Total of 800 units produced, both can trade
and consume 200 of cloth and cheese.
Without trade
India consumers get 200 units
of cloth and 50 units of
cheese.
France consumers get 50 units

32. Comparative Advantage Trade Example:
Two countries: U.S. and Japan
Two goods: computers and wheat
One resource: labor, measured in hours
We will look at how much of both goods
each country produces and consumes:
1.) If the country chooses to be self-sufficient自给
and does not trade.
2.) If it trades with the other country.
33. The U.S. has 50,000 hours of
labor available for production
per month.
--Producing 1 computer
requires 100 hours of labor.
--Producing 1 ton of wheat
requires 10 hours of labor.
Japan has 30,000 hours of labor
available for production, per
month.
--Producing 1 computer requires
125 hours of labor.
--Producing 1 ton of wheat
requires 25 hours of labor.
USA: JAPAN:
Comparative Advantage Trade Example:
38. Consumption With and Without Trade
U.S. consumers get
250 computers and
2500 tons wheat.
Japanese consumers get
120 computers
and 600 tons wheat.
Without trade
Total of 3470 units
39. Consumption With and Without Trade
U.S. consumers get
250 computers and
2500 tons wheat.
Japanese consumers get
120 computers
and 600 tons wheat.
Without trade
Total of 3470 units
1. Suppose the U.S. produces 3400 tons of wheat. How many
computers would the U.S. be able to produce with its remaining
labor?
2. Suppose Japan produces 240 computers.
How many tons of wheat would Japan be able to produce with its
remaining labor?
41. Japan’s Production With Trade

30,000 labor hours.

42. Suppose the U.S. exports 700 tons of wheat to
Japan, and imports 110 computers from Japan.
(So, Japan imports 700 tons wheat and exports
110 computers.)
1. Suppose the U.S. produces 3400 tons of wheat. How many
computers would the U.S. be able to produce with its remaining
labor?
2. Suppose Japan produces 240 computers.
How many tons of wheat would Japan be able to produce with its
