Why do women’s clothes button from the left and men’s clothes button from the right?

One option, why it is like that, is because of tradition. Women's clothes buttoning is the opposite to men's.When we move to the time in history when women were allowed to ride horses, it was probably proper for a lady to ride side saddle- she always rode on the left side. This caused a woman's blouses to come open in the wind. So the blouse was changed to button on the opposite sid, so as not to be obscene.

Personally I think that it is made to simplify our lives- if we have two shirts, that are the same for men and women it is easier to find which one belongs to whom.

Why are petrol caps on the driver’s side in some cars and on the passenger’s side in others?

One of the most frustrating experiences of driving a hire car is to pull up at a fuel pump as you would when driving your own car, only to discover that the fuel tank is located on the other side. Car manufacturers could eliminate this difficulty simply by putting petrol caps always on the same side of the car. Why is it like this?

In countries in which motorists drive on the right side of the road, such as the U.S., it is easier to turn right than to turn left across oncoming traffic. A majority of drivers will thus buy fuel at stations they can enter by turning right.

During busy times, all spots on the right sides of pumps would be filled even while most spots on the left sides of pumps remained empty.Suppose fuel tanks were always on the driver's side of the car. Drivers would then have to park on the right side of an open pump in order to fill their tanks.

Putting petrol caps on different sides of different cars means that some cars can access pumps from the left. And this makes it less likely that drivers will have to queue for fuel.

Unemployment- A global Perspective

Firstly, we have to start by defining what in unemployment, who are they?

An economic condition marked by the fact that individuals actively seeking jobs remain inhered. Unemployment is expressed as a percentage of the total available workforce. The level of unemployment varies with economic conditions and other circumstances. they receive job seeker allounce.

People with jobs are employed, people who are jobless, looking for a job, and available for work are unemployed, people who are neither employed nor unemployed retires, full-time homemakers, full-time students are counted as not in the labour force.

Employment counts part-time and temporary work, you are counted as employed, if you have a work, but did not work for reasons such as vacation or illness.

To be unemployed, one must have actively looked for a job within the period four we ks and be currently available for work.

The bureau defines actively looking for work as including contacting an employer, sending out resumes and checking union or professional job registers.

Unemployment differences are more persistent by population subgroup. The unemployment rate usually is the same for women and men, however for teenagers is different, because its much higher. The rate for African- Americans is generally much more higher than for a whites.

We can divide unemployment into three groups:

1. frictional- due to frictions in labour market- some must seeking for jobs, because their old job ends before an acceptable new ob begins.

2. technological- technological advance means capital is employed to replace labour.

3. structural which we can divide also into 2 part

- occupational- falling demand for labour in one sector where unemployed are unable to move to take up job vacancies in growth sector

- geographical- falling demand for labour in one region where unemployed are unable to move to take up job vacancies in growth regions.

Economic health indicator is the unemployment rate.

Most people who are not working are not counted as unemployment. When you are not the unemployment, that mean that the bureau of Labour statistic doesn't count you, in this situation your have to find a job, so you are a seeking for work.

Another thing that macroeconomics measure is the inflation rate, which appear when the overall price level in the economy rises and it is usually measured by consumer price index. Most economics says that the best inflation rate is when is hit to 2%.

Economy Up or Down?

How to tell if econom is up or down?
Economists have many different types of measuring economic performance which allow as to make historical and international comparisions. In this dayd any of them are perfect, so each must be examined carefully. However there are 3 main ways of measuring e.g. unemployment, inflation and GDP- gross domestic product.
One of the most popular of this three is GDP, which is in the market a value of all final goods and services produced in the economy over a special periodof time, thats mean one year. The gross domestic product does not conut everything which was bought and sold. The GDP statistic compare from country to country , because prices are different from one place to another one and year to year.

The interesting thing is that the USA has got the highest avarage income per persone in the world.

The ecnomy has got lots of ups and downs. Good example of this one, could be a recession, which we can define by a period in which the real GDP falls its can be defined also as - two consetiutive quartes of negative economics growth.

There is a rule of 72, which is the mathematical regularity that when we would divide this number by a growth rate it would be equal to the approximate number of years that it takes something to double.

What economists know about Economics policy

Firstly, we have to start by describing what is Economics and Economics policy. Then we will be able to talk about this.

Economics is the study of how to allocate scarce resources in the most effective way, among alternative uses. Economics policy is formed of fiscal policy(tax and government spending) and monetary policy(interest rates).It begins with the concept of scarcity, which exists whenever your wants or desires exceed your resources or what is available to you. The problem is that the choices involve trade-offs. Then the cost of something is the opportunity cost- next best alternative foregone.

When people make a decision, they think and compare the value of something and the benefit which they will have if they buy it. If they think that the expected benefits are greater than the expected costs, they do it. If it is the opposite, they don't do it.

Most the decisions are made on the margin. This means, they think about whether one should do a little more or a little less of something. We make them all the time. We decide to do more of something when we can get more benefit from it (that's depend).

The interesting thing is with temperature. Most people do not heat their homes as high as 70 degrees. There we can see the opportunity cost. If there is more warmth, they would probably have to spent less money for something else.

The quantity that you desire to buy at each price defines your demand curve- more people want to buy a product when the price of this good is lower, and desire to buy less when is dear.

Each person's demand depends on their budget, ability to pay and willingness to have the good.

If the market is competitive, the price will settle at an equilibrium level where the supply curve and the demand curve intersect.

There are many reasons why market can fail to achieve efficiency e.g. the market can be competitive, there is not an equilibrium etc. The government can change things to make it better, but that does not means that he will do so.
