Why has inflation fallen?

There is no doubt that the most encouraging aspect of Britain's economic performance in recent years has been the fall in inflation from a peak of over 20 per cent in June 1980 to a current rate of about 5 per cent. The speed at which inflation fell has taken many forecasters (including ourselves) by surprise. In this Economic Viewpoint we ask why the inflation rate has fallen. If we can understand why it has happened we are better placed to answer questions about the future. In particular we can try to decide whether the success in reducing inflation will be maintained and whether further cuts in inflation will be consistent with a fall in unemployment.     

CEO Overconfidence and Corporate Investment

We argue that managerial overconfidence can account for corporate investment distortions. Overconfident managers overestimate the returns to their investment projects and view external funds as unduly costly. Thus, they overinvest when they have abundant internal funds, but curtail investment when they require external financing. We test the overconfidence hypothesis, using panel data on personal portfolio and corporate investment decisions of Forbes 500 CEOs. We classify CEOs as overconfident if they persistently fail to reduce their personal exposure to company‐specific risk. We find that investment of overconfident CEOs is significantly more responsive to cash flow, particularly in equity‐dependent firms.     

Productivity and Inflation: a Paradox

In his Budget speech, Mr. Lawson drew attention to the greatly improved record of productivity growth in UK manufacturing:
"During the 1960s, and again in the 1970s, growth in manufacturing productivity in the UK was the lowest of all the seven major industrial countries in the world. During the 1980s, our annual rate of growth of output per head in manufacturing has been the highest of all the seven major industrial countries."
Ironically this success in regard to productivity may cause a problem in regard to inflation if the UK moves to a fixed exchange rate policy within the EMS. In this Viewpoint we report the consequence of such a move and also describe the possible required rise in the exchange rate if price stability is to be attained. We show that price stability requires the exchange rate to rise (i) to offset world inflation and (ii) to compensate for the productivity gap between the traded and non-traded sectors.     

The UK Balance Sheet

With net overseas assets of well over $100bn the UK is now the world's second largest creditor nation after Japan. This has come about because the UK current account benefited from large-scale oil revenues from 1980 onwards, which produced a series of current surpluses. Fortunately the funds were invested overseas at a time of significant recovery in world equity markets. As a result of the increase in its external assets, the UK now receives £5bn p.a. or more from interest, profit and dividend earnings on these assets - a valuable cushion to the run-down in oil revenues.     

Investment: A Worldwide Boom

Investment is booming: not only in the UK but also in the US, Japan and in Europe. In this Briefing Paper we seek to understand why this is happening – a global phenomenon clearly requires a global not a local explanation – and to consider whether the boom will continue. To this end (and not in order to discriminate between alternative theories of investment), we examine the main theories of investment and show that recent developments are consistent with models based on the accelerator, or which emphasize the cost of finance or which depend upon stock market valuation effects. And, no matter which theory holds, the implication is the same: investment will weaken in 1989 and this is an important element in our forecast of slower world and UK growth next year.
But there is an alternative view, which implies a more optimistic outlook. The theories which we consider are essentially cyclical: they focus on the key role of (volatile) investment spending in the business cycle. It may well be that the present surge in investment is a long-tern, structural phenomenon reflecting either a shift in the pattern of world demand or the spread of computer-based technology, which has raised the efficiency of investment. In this case, and notwithstanding this year's surge in investment, tighter monetary policy and the stock market crash, the present boom in investment may have a lot further to run.
