 The economic problem, mechanism of choice, the mechanism of choice is going to deal with the problem of allocation of resources and for allocation of resources how the decisions are made, these decisions they are particularly come under the theme of mechanism of choice. In general, there are three types of the mechanism, one is called invisible hand, the other is called the government intervention and the third is mostly the mixed economy. The three questions that mostly economists has to answer, they are what to produce, how to produce, how much to produce and for whom to produce, so for these three questions all the answers they have to be provided by a combination of various policies, rules, set objectives and the methods, so these methods can vary from one type to any other and mostly the combination of these methods and system it will be under the mechanism of choice. Now we will explain the first method or the mechanism of choice that is the invisible hand, here the invisible hand is not the actual hand rather it is a metaphorical concept that was given by the Adam Smith, as per Adam Smith the markets they should be able to re correct or self-regulate itself, there should be a force invisibly available in the markets that gives the energy or the system to those markets that if any type of irregularity or increase or decrease it comes to the surface it can correct itself. We can take the example that if the price of any commodity will increase it will provide the signal to the producer and under the motivation producer will produce more and in other words if we say that if the price of a commodity is more than the price of a commodity then the producer increases the cost of production in the response, as soon as it increases then in the market the one who is selling his product increases its price and similarly if the demand is increasing in the form of increasing the signal from the market then the producer can increase the production or the production he is providing can increase the price of the product, so this is a cycle of forces that if we say self-correcting mayors then that self-correcting system means there is an invisible hand that will prevail in the market to correct itself. One another concept that is mostly utilized in the explanation of the invisible hand or the free markets or the market structure that is called the LESSES FEAR, LESSES FEAR is the term that is given by a French economist and in other words the LESSES FEAR means let it to be or if we say it in simple words then LESSES FEAR means to allow something to be self-corrected or which we say in Urfaia that something should automatically be done, so if we say in the market as a self-correcting mode then we say that the free market forces are allowed to work, there is no intervention in it and if there is a minimum intervention with market forces then we say that there is an invisible hand working as a correcting measure in the markets and if we look at it in this way then we will say that what will happen in the correcting measure, the choice of consumers will be a signal, the choice of the producer will be a force when it is going as a message, they will decide their demand through price and similarly when their utility is maximized then the demand that will increase the producer will respond to it and similarly if we collect all the demand of the consumers then it will give signal to the producer in the form of aggregate demand and the producers will respond to it by increasing the quantity in the form of their cost that if the demand is less then the quantity of production can be reduced and it will give signal by attaining its profit, so overall if we say invisible hand then it will increase the structure of the producer and it will increase the decentralized system and it will explain decentralized system and decentralized system.
