What is causing inflation in Argentina?

I will write about the causes that have been stimulating the growth of prices since 2008. The prices have been growing over an annual rate of 10/15% since 2008. Nowadays, it has reached at annual rate of 23%, which makes Argentina one of the countries with the highest rate of inflation in the world.

To begin, it’s important to say that, as it is well known, the economy is a social science that depends on lots of factors, such as the behavior of people.  That’s why, in difference with other science like physics or medicine, it is difficult to understand and prove exactly what the causes of some events are. But even though we are a step below exacts science, we have made a great improvement in the past decades with the incorporation of economical models. In few words what we try to do is make some suppositions about the factors that we aren’t able to manage and try to connect logically the relations between the variables that we can manage. Then we use econometrics to prove that model with reality. Of course, there are lots of authors (often called postkeynesians) that are not in favor of the uses of these mathematical models. But more or less due to that, we are more advanced than other social sciences.  

To explain the inflation I will introduce the quantity theory which is a simple equation created by the neoclassical school lots of years ago. What this equation says is basically that if we inject more money in the economy, it will surely increase prices.  That’s because the excess of money will produce an excess of demand in relation with the offer. This law is quite simple and logical, but it’s not always true. That’s because at the same time some other factors of the equation that were supposedly fixed by neoclasicals can vary in reality (in fact, that’s what Keynes proposed). These factors are: (i) an increase of the demand of money (growth of GDP), (ii) a decrease of the offer of money (government policy) (iii) a paralyze of the demand of money for transactions (crisis, liquidity trap).

In the case of Argentina, the authorities have been making an expansive fiscal and monetary policy during those years. The incidences of these factors that can cut off the expansive effect of the monetary policy pulling down the increment of prices haven’t been present in Argentina’s economy (except for 2009). That it can be an evidence of the growth of money may be one of the causes (“shock”) of the inflation in Argentina.

Unfortunately, because economy is a social science, is difficult to argue that the raises of prices started surely with the growth of money.  But what we can surely argue is that if the growth of money is not what is producing inflation, at least is validating the raises of prices. That is a truth and a responsibility of the government.
