Tag: Consumption function

In the blogs The capital adequacy of UK banks and A co-operative or a plc? we focus on how British banks continue to look to repair their balance sheets. To do so, banks need to ‘re-balance’ their balance sheets. This may involve them holding more reserves and equity capital and/or a less risky and more liquid profile of assets. The objective is to make banks more resilient to shocks and less susceptible to financial distress.

This will take time and even then the behaviour of banks ought to look like quite different from that before the financial crisis. All of this means that we will need to learn to live with new banking norms which could have fundamental consequences for economic behaviour and activity.

The increasing importance of financial institutions to economic activity is known as financialisation. It is not perhaps the nicest word, but, in one way or another, we all experience it. I am writing this blog in a coffee shop in Leicester having paid for my coffee and croissant by a debit card. I take it for granted that I can use electronic money in this way. Later I am going shopping and I will perhaps use my credit card. I take this short term credit for granted too. On walking down from Leicester railway station to the coffee shop I walked past several estate agents advertising properties for sale. The potential buyers are likely to need a mortgage. In town, there are several construction sites as Leicester’s regeneration continues. These projects need financing and such projects often depend on loans secured from financial institutions.

We should not perhaps expect economic relationships to look as they did before the financial crisis. The chart shows how levels of net lending by financial institutions to households have dramatically fallen since the financial crisis. (Click here for PowerPoint of chart.)

Net lending measures the amount of lending by financial institutions after deducting repayments. These dramatically smaller flows of credit do matter for the economy and they do affect important macroeconomic relationships.

Consider the consumption function. The consumption function is a model of the determinants of consumer spending. It is conventional wisdom that if we measure the growth of consumer spending over any reasonably long period of time it will basically reflect the growth in disposable income. This is less true in the short run and this is largely because of the financial system. We use the financial system to borrow and to save. It allow us to smooth our consumption profile making spending rather less variable. We can save during periods when income growth is strong and borrow when income growth is weak or income levels are actually falling. All of this means that in the short term consumption is less sensitive to changes in disposable income that it would otherwise be.

The financial crisis means new norms for the banking system and, hence, for the economy. One manifestation of this is that credit is much harder to come by. In terms of our consumption function this might mean consumption being more sensitive to income changes that it would otherwise be. In other words, consumption is potentially more volatile as a result of the financial crisis. But, the point is more general. All spending activity, whether by households or firms, is likely to be more sensitive to economic and financial conditions than before. For example, firms’ capital spending will be more sensitive to their current financial health and crucially to their flows of profits.

We can expect particular markets and sectors to be especially affected by new financial norms. An obvious example is the housing market which is very closely tied to the mortgage market. But, any market or sector that traditionally is dependent on financial institutions for finance will be affected. This may include, for example, small and medium-sized enterprises or perhaps organsiations that invest heavily in R&D. It is my view that economists are still struggling to understand what the financial crisis means for the economy, for particular sectors of the economy and for the determination of key economic relationships, such as consumer spending and capital spending. What is for sure, is that these are incredibly exciting times to study economics and to be an economist.
