Money serves as a medium of exchange and store of value. Price provides an important clearing mechanism in a society. Here we are going to explore the interesting dynamics between money and price.

In a free market, when the quantity of money is fixed, the fact that the price of an apple is $1 and that of a Parker pen is $2 has tremendous implications. It takes knowledge, ingredients and time to grow an apple while it involves branding, material, and capital to produce a Parker pen. What the market says here is that the total efforts put into producing the pen are worth twice as much as the efforts of growing the apple. There are thousands of valuations communicated through the market by this simple exchange. Over time, with advances in technology, it takes fewer efforts to produce more goods. The same farm that used to grow 10,000 apples can now grow 20,000 in half the time. While the ratio of exchange between apples and pens might still be 2 to 1, since it also takes less to produce a pen, in a world where the quantity of money is fixed the price of both apples and pens should decrease (i.e. 80 cents for an apple, and $1.60 for a pen).
