Hahn argues that in a general equilibrium model, the value of money has to be zero in equilibrium. However, in the real world, money has a positive value. This paper critically analyses the Money-in-Utility approach, which attempts to solve the problem within this framework. In a general equilibrium model, if there are n-good markets, all markets clear with just n-1 real conditions (Walras Law). Money has no role to play. It is like a barter economy.
Hahn derives a set of conditions with n goods of which, the zero-th good has price zero. With this set of conditions, if we start with excess supply of this zero-th good, it is possible to derive equilibrium in a general equilibrium model. Hahn goes on to assign this zero-th good to ‘fiat money’. He believes that all the properties of this good are satisfied by fiat money itself- it has a value of zero and still continues to be circulated in the economy. In this model at equilibrium, money has no value.
However, Patinkin believes that we must start with a positive value of money. This is because of uncertainty of the exact instant of sales and purchase in a given time period. He assumes that no transaction is possible without the intermediate role of money.
Patinkin proposes the neutrality of money in the presence of expectations and the Cambridge constant ‘k’ actually being variable according to the following equation:
Referring to the Quantity Theory of Money, M= kPY;
Given output, neutrality of money is ensured only when the Cambridge constant ‘k’ is a constant. Under this, we need to assume unit price expectations. This implies that there will be no finite value of money; hence further need of the assumption of flexible prices, which goes beyond the framework.

...y (MIU) approach, which attempts to solve this problem within this framework, suffers from unwarranted assumptions. It is unclear why household actually hold positive amounts of money and how does it provide a positive utility to them. Also, even though Patinkin and Walsh argue for a positive value of money in equilibrium in the MIU model, it does not solve this conundrum.

Money is the main source of power in the world, but in ways it can be viewed as good or bad depending on the situation. It has a negative connotation when mentioned by the word “acts”. “ Acts” means to perform a fictional role. Which shows that most things involving money are fake. Though humans associate being fake with being morally wrong,but its somehow acceptable if there is a greater power involved. Another definition for acts is to take action;do something. In this case to take an action can be either good or bad. There are many ways to come across money, but nobody cares if it is good or bad because it deals with a greater power.
It is also believed that wealth should be non-existent. This is only possible if cl...

The problem with balancing an economy is that human judgment and evaluation of economic situations enter into the equation. Establishing a constant growth level in the money supply would eliminate the decision making process of the central banker. The problem with human intervention is the short-sided nature of many of the policies designed to aid the economy. Such interventions, which yields unintended negative consequences, is the result of the time inconsistency problem. This problem is understood through situations during which central bankers conduct monetary policy in a discretionary way and pursue expansionary policies that are attractive in the short-run, but lead to detrimental long-run outcomes. Friedman believes that by leaving money growth decisions to an individual, the results are poor long-run management and eventually high inflation rates, an obvious detriment to the economy.

Paul A. Samuelson, one of the men who made Harvard’s reputation, made various contributions to modern economics. Samuelson brought numerous theories to the table, showing that math is an effective and necessary component of understanding economics. Furthermore, he discovered a new obstacle regarding inflation, known as “cost-push” inflation. But most importantly, Paul A. Samuelson has shown that economic theories can be timeless, however their implementation evolves around the current economic circumstances that are in play.
Today money is faith in the person paying us and belief in the person issuing the money he uses or the institution that honors his money. This trust has no end, it can be extended to a greater number of individuals. The establishment of money freed individuals from dependence on land as an essential resource for production and freed commerce from the need to barter and trade.... ... middle of paper ...
Money supply is the availability of money in the hands of the public (economy) that can be used to purchase goods, services and securities. In macroeconomics, the price of money is equivalent to the rate of interest. There's an inverse relationship between money supply and interest rates. As money supply increases, interest will decrease. On the other hand, interest will increases as money supply decreases. It is very important to understand that the economy works at market equilibrium. There are several factors affecting money supply; and these contributing factors will be the main focus of this paper. Understanding the basic principle on money supply is imperative to have a good grasp on the macroeconomic impact of money supply on business operations.
Today, more than ever, there is great debate over politics and which economic system works the best. How needs and wants should be allocated, and who should do the allocating, is one of the most highly debated topics in our current society. Be it communist dictators defending a command economy, free market conservatives defending a market economy, or European liberals defending socialism, everyone has an opinion. While all systems have flaws and merits, it must be decided which system is the best for all citizens. When looking at the financial well being of all citizens, it is clear that market economies fall short on ensuring that the basic needs of all citizens are met.

The invention of money was a major improvement in peoples’ lives. In the past, people usually had to travel all day to find the person who is willing to exchange their goods. In addition, the goods people want to exchange did not have the standard value of measurement. This led to unequal exchanges. Furthermore, it is not convenient to carry heavy goods from one place to another for an exchange. To solve these issues, money will be the only solution. Later, people tend to develop money from cowry shells to credit cards for the convenience and to improve their society.
