Keynes takes issue with the Victorian idea [that still seems to be shared by a lot of conservative commentators] that a high rate of saving is automatically a good thing. He highlights the paradox of thrift in The General Theory.
If people’s savings rates increase then [if their incomes remain constant] their consumption must decrease. Decreasing consumption means a decrease in the level of output and employment – as there will be a falling-off of business for some firms and so they will produce less and lay off some workers. This fall in output and increased unemployment may well then feed through into decreased incomes for the population as a whole. Keynes cites the
Fable of the Bees and even a verse from Proverbs to illustrate his point. What is a good idea for an individual or household [increasing their savings rate] may well be a bad idea for the economy as a whole. It is the fallacy of composition to think that what is good for one household is good for the country [or the world] as a whole – it is a fallacy many people fall into.
Remember – what spurs economic output is producing things for others’ consumption. If others don’t consume the output, then there is no need to produce it and so output and employment will fall. Of course, in an open economy, surplus output can be exported. However, by definition, in the world as a whole that is not the case. Imports must equal exports.
The most significant point that I took away from reading Keynes is that greater savings in an economy are not a good thing in themselves. They need to be invested. Depending on how you define ‘savings’ and ‘investment’ they can defined as identical in quantity. However, a rise in savings could, all other things being equal, move things from one equilibrium to another equilibrium – with lower output and employment. In contrast, a rise in investment could lead
to more spending on capital goods, more employment/higher wages in capital goods industries and greater consumption as a result. A rise in investment can thus get a virtuous circle going; a rise in savings could get a vicious circle going.
Keynes thus emphasises the need for the state, in a situation like in the 1930s when output & employment are falling, to engage in spending aimed to raise the level of investment. By doing so, it will give work to some people. They will then, especially if on a low income, consume the bulk of it. This consumption will then boost the sectors of the economy that depend on their consumption – that produce the consumer goods they want. That will have a knock-on positive effect on the economy and will help raise output and employment.
Keynes notes that investment decisions are often made on the basis of what he dubs “animal spirits”. Businessmen and senior managers will often make investment decisions to buy new capital or new plant based on their optimism or pessimism. If they are optimistic they can sell the goods they produce at a good price, then they will invest and expand their production. If they are pessimistic then, however low interest rates are, they will not borrow to invest. If the animal spirits of the private sector are not such as to favour greater investment, then the key point to take away from Keynes is that the state should be the investor of last resort and should spend on the national infrastructure to avoid a spiral of declining confidence, declining investment and declining output.
Another interesting thing Keynes draws attention to is the preference for liquidity among investors. People want to have easy access to their money when they save it. However, most productive capital investments require large sums of money to be committed for a long period of time. This means that people may often ‘hoard’ money or other goods as a form of ‘saving’ rather than save it in such a way that it can be easily invested [i.e. by making a long-term loan to a business]. It also emphasises the importance of banks as institutions, since they try and bridge the desire of depositors for easy access to their money and the desire of borrowers for long-term loans at fairly stable rates.
Hoarding money or gold or other valuables, although it might prove useful to an individual household, is not beneficial to the economy as a whole as this ‘capital’ can not be invested. Keynes says,
“That the world after several millenia of steady individual saving, is so poor as it is in accumulated capital-assets, is to be explained, in my opinion, neither by the improvident propensities of mankind, nor even by the destruction of war, but by the high liquidity-premiums formerly attaching to the ownership of land and now attaching to money”. Interest rates, in Keynes’ view, have to be higher than they ought to be – in a capitalist (or feudal) economy – to induce people to part with liquidity.
Later on in the General Theory, Keynes writes a paragraph in reference to India – a society which he feels has failed to grow much economically because of a disinclination to lend and invest money for long-term projects at reasonable interest rates. He says,
“The history of India at all times has provided an example of a country impoverished by a preference for liquidity amounting to so strong a passion that even an enormous and chronic influx of the precious metals has been insufficient to bring down the rate of interest to a level which was compatible with the growth of real wealth".Keynes says that Britain, in the golden age of
laissez-faire for her, was able to develop political, social and financial institutions that were able to turn savings into productive investments. Even then, however, he notes that the rate of return demanded for safe government bonds was in the region of 3% or 3.5%. Slightly riskier commercial investments carried a return of 5% or more. This means, under capitalism, that the rate of return the entrepreneur would need to get from his investment to make a profit and to repay his creditors would have to be much more than that. In the 19th century, when the world was poorer than it was when Keynes was writing in the 1930s, there were more such investment opportunities. Now, it seemed to Keynes that the marginal rate of return to capital was falling. As such, to spur the increased investment needed to have full employment and to have output growth, interest rates would have to fall lower and lower to make such investment profitable.
Keynes thus thought that the state should keep interest rates low by monetary policy and by trying to make capital more abundant. Only by doing so would more investments be financially worthwhile.
Keynes was not an anti-capitalist in the sense that Marx and others in the Marxist tradition were. However, as a thinker, he became sceptical of
laissez-faire – seeing the economic problems that faced Britain after the First World War. He, therefore, as a progressive Liberal wanted greater steps taken by the government – not to directly control industry as those further to the left wanted – but to intervene in the market and in the economy to achieve desired goals. These desired goals, given the high level of unemployment in Britain even during the boom years of the 1920s and given Britain’s relative economic decline vis a vis the US and some continental European countries, were full employment and a greater investment and growth.
