What are the reason for the price raise in a country?.  

Our days' capitalism and democracy aren't anymore attributes of a nation, of the people or of a culture or another. They mutated into political instruments in the hands of various groups of elites, rulers, etc. Is not the will of the people governing the world, but the will of these important groups of interests, who decide everything from how liberty should be defined to what is the price for a certain commodity in a certain market.

Either you like it or not, free market economics is just an atavic reminiscence of the past and, despite the every day rhetoric, it found itself a nice warm place in the dustbin of history. Either you like it or not, global crisis, revolutions, wars, nuclear proliferation, price variations, stock exchange evolutions etc are designed and implemented by world's most important pupetteers.

But at least some of us are able to admire their skills when playing with the political strings...

There are many reasons for the price in the country. among them Inflation is main factor, inflation is a rise in general level of prices of goods and services in an economy over a period of time. When the price level is rising each unit of currency buys fewer good and services . then inflation effects of economy, then hoarding goods, lack of production . recession. hyperinflation, scarcities , monitory policy of govt. open market operations, interest rates, reserve requirements. etc
