Very interesting article about fatherless families

I have read a very interesting article about families, where children haven't got a father. So, according to the American sociologist Charles Murray, there are many increasing numbers of young, healthy,low-income males who choose not to take any jobs. Many of them start to do some crime, such as violence on the streets and regular drug abuse.

The main problem of that, because these boys brought up by female and they didn't have any right strict advices from male and their disciplines and responsibilities of society have broken down. They have many big psychological problems in their lives because the should become "real fathers" in family instead their father which they havent'got.

Nowadays in Great Britain it becomes larger and larger numbers of children who lost self-control and concept that actions have consequences. To solve this problem, teenagers have to change their structure of their mind, to avoid problems such as violence, drug abuse etc.

Mali's farmers discover the power of jatropha

Mali is the african country which constitutes one of the most poorest countries in the world, because there are not any quantity and quality of factors of production that are needed to increase their productive.

Once in Mali was found a very interesting fruit, jatropha, which was originated from South America. People used this fruit for fence agains wild animals, because its smell and taste repel animals. Also, it used for eliminating erosion.

After some years, people in countries like Mali, India, China, Malaysia have found that this fruit can be used for biofuel, which is very important and valuable in the world. In Mali people use jatropha for making electricity in poor areas. And government with this fruits assistance solved many problems with electricity which they haven't got for many years. And now in many countries like Brazil,Argentina, Peru, government make many plantations of jatropha for making biodiesel fuel which is very useful for many types of machines. Also many airline companies use a biodiesel from jatropha. And here is a massive economy of many, because biodiesel fuel is much cheaper than a fuel which making from oil, and it's a really big economy. Every year demand for jatropha fruit is increasing more and more.

What is economics?

What is economics?

So, everyday I know many new things about economics, such as economics is the study about how to allocate scarce resources in the most effectime way.

Economics is everywhere in the world, every person and every big organisation in the world try to to do the best quality and to save their money. Managers of companies try to decide what to produce and in what qualities.

Also many people in the world try to find the special way where they can make a profit even they don't have much resourses or these countries are poor: for example there are some poor countries in the world such as Senegal, Madagascar, Republic of Kenya, these countries don't have a good economiocs system and they don't have useful resourses, but they make a really big profit by tourism, and that's a great economy and great possibility to eliminate poverty.

Also in many rich countries such as Germany, Great Britain, Belgium, Sweden etc, government try to do many advantageous things to save their profit, for example they employ lots of people from third world countries to work in shops, some companies, and government of these countries save much money, because they have cheap work force and it is a big economy.

Also I have known about command (planned) economy.

Everyday government think about how to improve their economy and be in the leaders in the world. They think about special decisions such as what to produce and how to produce. For producing government needs much resources, like oil, gas to make some inventions for using, but there many countries that don't have any resources and they buy them from many other countries.

The reasons of rising prices of cocaine.

So, As far as I am concerned, cocaine is inelastic product, people buy it everytime and it doesn't matter how much does it cost, and the main reason of rising prices, because people who sell cocaine know that every drug addict will buy cocaine, because they depend on it. But there is a problem in many countries, such as prohibition on using and selling drugs and it's very difficult to find any cocaine and that's why people rise prices on cocaine, for example: in Afganistan there are biggest drugs manufactures in the world, but now it becomes more difficult to supply with cocaine to many countries and bosses of it rise their prices because they know that anyway many people will use cocaine in spite of prices on it.
Drugs business is one of the most profitable occupation in the world and demand for it will be very big in any time.

Let's talk about benefits and the cost of using the biggest ship to transport!Benefits:I think there will be less pollution for unit carried, also the massive capacity, because they can transport a lot of containers. Also it will reduce the price for consumer, because the cost of transport will decrease by the big ship. Low labour cost as well, because there are only 13 crews which case study mentioned. Also low fuel costs per container carried.Costs:To Build the biggest ship should cost a lot, also if a ship is very big, the speed will reduce because when they want to pass some canal, for example Suez canal, they will use a lot of time. Also there are railway line needed. If they want to save money, the capacity of this ship must be full.Then, I would like to talk about another thing, If UK trade with China, they can spend less money to import, also when they transport some products from China to UK, they can create jobs for transport. Also it's leading to lower cost push inflation, because the products from China are cheaper, which reduce the price of goods. However, trade with China might reduce the manufacture job in UK.
