Sometime back Priya had forwarded me the following mail from an IITK newsgroup asking me to explain if it is true.

I had sent her back an explanation, which she recently acknowledged ‘made sense’ to her.🙂 So, I thought I will post that too here. Please note that you would not find anything very profound here. It was written keeping in mind those who might not know anything of Economics and hence basically discusses very simple Economics concepts. Also all the things are explained only conceptual. I have not verified any data about who is saving how much and who is spending how much! Just in case someone is interested. And mind you – read it your own risk. The author does not take any responsibility for any intellectual damage the following piece can cause to the readers. And excuse the informal tone of a presumably serious discussion. I am reproducing the mail verbatim!
The economic growth of a coutnry is largely measured in terms of Gross Domestic Product (GDP), which can be defined, in one way, as follows
GDP = C + I + G + NX
where C = consumption in the economy
I = Investment in the economy
G = Governent Expenditure in the economy
NX = Net Exports in the economy
(At an intuitive level, these are the four purposes for which any productive activity will be undertaken in the country. And hence by
measuring them, productive economic activities can be measured.)
Another term that would be useful in the discussion is S = Savings in the economy.
Let’s understand the relationship and differences between savings and investments in the economy. In this context Investment means “Investment in Physical Capital” like machines/equipments etc. which can be used for production. Investment, in say stock market is not “Investment” in the economic sense. It is “saving” as are our deposits in Banks and other such institutions. Only if a company that gets money through stock market uses it for some capital formation, does the saving gets converted to investment.
This also brings us to the relationship between saving and investment. While saving does not automatically guarantee investment, it is necessary for investment. What someone saves, is what some one else invests. Institutions like Banks, Stock markets etc. facilitate the mobilization of saving and take it from the saver to the investor. This investment then contributes to the economic growth by increasing GDP.
Saving need not automatically translate into investment. As in if I have kept 1 lakh rupee in my wallet, it is not going to be an investment. However, if I keep it in bank, the bank will possibly lend it to someone interested in investing. The interest I get on my saving induces me to save. Of course bank can give me that interest only if the person investing it is getting even more out of it. I am happy with the interest, since I am not interested in taking the pains of investing.
What could be the alternative uses of this money I am saving and the other person is investing. One possibility is that bank does not lend it for investment purposes, but for consumption purposes (e.g. it might give away the money as house/vehicle loan). Then, my saving gets converted into somebody’s consumption. For his/her consumption that person is ready to pay the bank more than the interest I get.
And yet another option is that I do not save at all and use all my money in consumption.
What is the implication of using money in investment vs. consumption (my own or somebody else’s?)? If everyone in the economy goes on consuming and no savings are mobilized towards investment, then with time, the capital in the econmoy will deteriorate. This capital includes the equipment/machinery we are using for the production of what we are consuming. So, after a while (this “a while” can range into decade possibly, but it will happen), we will not be left with the means to produce at all (or at least there will be a deterioration). So, while today, by using all the moeny in consumption (C) I can increase my GDP, tomorrow I will run into trouble if I have not saved and invested in the physical capital! Thus, investment means that we sacrifice some consumption today, so that we can consume enough tomorrow. Of course, the eternal question before all the economies of the world is how much of investment and how much of consumption? We certainly do not want to make life unnecessarily tough/bad for people today by investing too much. But we can’t be too ‘extravagent’ and compromise the consumption of future generations.
Now, we can see the given case in the light of the above framework. Keep in mind that I had ignored the movement of saving across the countries in the above. This will come into picture in this case.
As per this article, Americans are consuming and not saving (much) domestically. Japan is saving, but not investing the whole of it in its own coutry. Rather it is diverting a large part of it to America. Now, question is what are Americans doing with the money. Suppose a Japanese person has put the money in an American Bank. Now, is the American Bank lending the money for a housing loan or to a company for creating capital? If it is for housing loan and not just this bank but all the banks taking money from Japanese are doing the same thing, how long can they sustain it only on consumption. So, long as physical capital is sustaining consumption and hence economy is growing and hence the person is ready to pay the bank more than the interest bank will give to the Japanese person. But how long? Someday they will run out of production resources (capital) and then?
Now, if Japanese are diverting their savings to America, why are they doing it? What are they doing with the returns they are getting? If they are using that return for investment in their country, they are building a better future. If they are using it for consumption, they are enjoying their life without taking the pains of investing in the physical capital. But of course, in the later case, they are also risking their future. What happens when in future Americans run out of physical capital and hence can’t consume and hence have low GDP and can’t pay the Japanese back?
But let me hope that American as well as Japanese economists and governments are at least as intelligent as I am (and now you too :-D). Hence, even while cosuming a lot Americans are taking care of their investments for future; and despite diverting their savings to America, Japanese are consuming and investing enough. And hopefully what they are diverting to America earns them better returns there than it would earn them in their home-country.
So, you see, it depends on where a particular economy is presently there. How much of consumption it can afford and still have enough for investment? Consumption is important. Effect of investment on Economic growth comes with a time-lag and consumption is the best way to ensure
the growth in short-term. But investment is important as well. Short as well as Long term welfare is to be kept in mind. Probably Americans can afford to consume a lot. Can we Indians do it?
Several things would come into picture there. What I have described is obviously a simplistic picture. Very often the actual action of people/government in a country does not solely depend on the economic wisdom. The deficit of America and the fact the it is the largest borrower in the world is indeed a matter of concern. If in future its economy collapses, it will certainly have drastic repurcussions on all the countries. Many a times political considerations over-ride the economic concerns, even in America🙂
And then, many a times a simple measure like GDP is not enough. That’s where the concepts like Developmental and Welfare economics come into picture. At times even if there is a best way to ensure GDP growth, it may not be the best way for the well-being of a large part of the society. Thus, a simplistic argument can’t be taken just like that. Even if one accepts that consumption is the best way towards Economic Growth, it need be good from the point of view of equity and welfare. At what cost does the consumption come? Who consumes and who suffers?
I must stop before I am labeled as communist😀
If you have indeed read upto this, questinos are welcome. And also a feedback on how good or bad an Economics teacher I shall make :-p
