Briefing Paper: Non-Manufacturing Investment and UK Aggregate Demand

The standard view of business fluctuations gives the leading role to investment, in both fixed capital and stocks, which raises aggregate demand in boom and reduces it in slump. The recent behaviour of the UK economy seems to have been a particularly marked departure from the standard model. Movements in personal consumption have played an unusually important role in both the rapid increase of demand from 1986 to 1989 and in the current recession. Stock investment, owing to improvements in the technology of stock control, is no longer a driving force. Manufacturing investment, while rising during the boom, contributed relatively little to increasing demand. The conventional wisdom now has it that recent UK experience is that of a consumption driven business cycle.
This Briefing Paper argues that this down-playing of the role of investment has been overdone. What has deceived the eye is the concentration on manufacturing. Investment did make a very large contribution to the recent boom, with the biggest increases in investment undertaken by non-manufacturing industry: a component of demand which attracts little regular scrutiny and less understanding. The textbook model still applies to the UK.

Last year saw the most coordinated cyclical upturn in the world economy since the early I970s, with OECD output rising 4per cent, industrial production and world trade even more rapidly. The boom in demand, which followed five years of continuous expansion, has outstripped supply and prices have begun to accelerate. To tackle inflation, the G7 monetary authorities have tightened policy over the last year, reversing the short-lived drop in interest rates necessitated by the stock market crash. This tightening may have to go further, especially in Germany and Japan where the effects of a rising oil price and higher indirect taxes are being exacerbated by currency depreciation. Although the rise in interest rates came too late to stop inflation rising, it has beet pursued with sufficient vigour to prevent inflation from seriously breaching the 5 per cent level. It is on these grounds that we forecast a relatively soft lending for the world economy on output, with growth continuing at 2.5–3per cent, accompanied by a limited reduction in inflation which stays in the 4–5per cent range. Progress on current account balances is also likely to be sluggish: in the absence of a serious attack on the budget deficit, the US deficit is likely to stay in the region of $140bn a year.

The London Business School with Gower Publishing

With the benefit of hindsight, we can see that the course of the world economy in 1988 was a product not so much of the stock market crash of October 1987 but of the reaction to the crash. Monetary policy and to a lesser extent fiscal policy were eased and consumer spending responded to cuts in interest rates and rising real incomes. With the world recovery in its sixth year, capacity pressures began to emerge and investment also boomed, helped by a lower cost of capital. As a result of this strong private sector demand, OECD output increased 4 per cent in 1988 as a whole and industrial production and world trade rose even more rapidly. Against the background of buoyant demand and output, inflationary fears have resurfaced. Since the spring monetary authorities in most countries have been tightening policy, raising interest rates by early 1989 above the levels which helped bring about the stock market crash. Their aim is to effect a slowdown in demand before a significant upward movement in inflation and inflationary expectations takes hold. In our judgement the present policy stance will achieve its aim of a "soft landing" for the world economy. The pick-up in world inflation is contained below 5 per cent and by the second half of this year inflation eases, paving the way for a relaxation of monetary policy. Output growth slows from 4 per cent to 3 percent in 1989 and 2 per cent in 1990, picking up again as interest rates are lowered in 1991–2.     

Dependence structures between Chinese stock markets and the international financial market: Evidence from a wavelet-based quantile regression approach

In this study, we investigate the dependence structures between six Chinese stock markets and the international financial market including possible safe haven assets and global economic factors under different market conditions and investment horizons. The research is conducted by combining a quantile regression approach with a wavelet decomposition analysis. Although we find little or insignificant dependence under short investment horizons, we detect the strong asymmetric dependence of oil prices and the US dollar index on the six Chinese stock markets in the medium and long terms. Moreover, not only is crude oil not a safe haven, it may damage Chinese stock markets as it increases over the long term, even in bull markets. Meanwhile, appreciation of the US dollar (depreciation of RMB) damages (boosts) Chinese stock markets during bull (bear) market conditions under long investment horizons. Moreover, we find that VIX (volatility index)-related derivatives may serve as good risk management tools under any market condition, while gold is a safe haven asset only during crisis periods.     

Should we worry about the decline of the public corporation? A brief survey of the economics and external effects of the stock market

In recent years, the number of listed companies has been declining in many countries across the world. This paper provides a selective survey of the literature on the real economic effects of the stock market to assess the potential effects of this decline and determine whether it is likely to continue. The leading economic role of the stock market’s primary market, in which firms raise capital by issuing new shares, is to help growing firms secure financing. We discuss providing and certifying information, coordinating investors, and easing the redeployment of capital as the means through which capital allocation can be efficiently achieved. The main economic roles of the stock market’s secondary market, the trade in existing shares, is to provide liquidity to shareholders, to aid in price discovery and to provide diversification opportunities. Positive external effects from an active stock market may arise for consumers, labor and private firms due to increased corporate investment, more socially responsible business strategies and a more positive business climate. Negative external effects on capital allocation and productivity can arise from short-termism, market mispricing, and increased cross-ownership. Local stock markets can spur innovation and foreign direct investment (FDI) and reduce the risk of early cross-border acquisitions. Given the myriad of useful economic functions the stock market performs, a future entirely absent of public companies is difficult to imagine and the decline is therefore likely at some point to come to an end. Whether we need to worry about the decline depends on the relative importance of the positive and negative external effects, a topic we feel warrants more research.     

Geopolitical risk and stock market volatility in emerging markets: A GARCH – MIDAS approach

In this study, we examine the connection between geopolitical risk (GPR) and stock market volatility in emerging economies. Our motivation for this study is premised on the need to assess both the predictability and the associated economic gains in relation to the subject in order to offer more useful insights to investors and practitioners. To the best of our knowledge, this is the first study that jointly considers these objectives. Consequently, we employ the GARCH-MIDAS framework which accommodates mixed data frequencies thereby circumventing information loss or any associated bias. We find that emerging stock market volatility responds more positively to geopolitical risks although the act-related GPR index offers better out-of-sample forecasts than the threat-related GPR. We also find that accounting for global economic factors in the predictability analysis is crucial for robust outcomes. Finally, we provide some utility gains of including GPR in the predictive model of stock market volatility while also highlighting some useful implications of our findings for investment and policy decisions.     

Monetary and real causes of investment booms and declines

The 1900s have marked two major investment booms in the United States. The boom of the 1920s was followed by the Great Depression of the 1930s, in which investment demand fell sharply. The second boom, of the 1950s and 60s, has been followed by a period of lagging investment. The economics literature reflects two disparate schools of thought on long-term investment behavior: the accelerator theory and the monetarist theory. This paper develops an investment function that interrelates monetary and real variables. Analysis of the investment function identifies several powerful non-monetary forces that can trigger investment booms with subsequent collapse due to overexpansion. Money is shown to be a critical element in sustaining a boom, but monetary contraction during the succeeding decline appears to be a symptom rather than essential cause of investment stagnation. The results thus point toward an integration of the monetarist and accelerator theories.     

Impact of COVID-19 pandemic on stock markets: Conventional vs. Islamic indices using wavelet-based multi-timescales analysis

We empirically explore the effect of the COVID-19 pandemic on Islamic and conventional stock markets from a global perspective. We also explore the co-movement between Islamic and conventional stock markets. Two comparable pairs of conventional and Islamic stock indices – Dow Jones Index and FTSE Index are considered in this study. Employing Wavelet-based multi-timescales techniques on the daily data from 21st January to 27th November 2020, our findings indicate that the pandemic creates identical volatility in both stock markets. Our findings further suggest that both markets are strongly associated and tend to co-move highly during our sample period, rebutting the decoupling hypothesis of the Islamic stock market from the conventional market. However, the Shariah screening process fails to provide immunity to Islamic stock markets against financial crises. Our findings suggest that investors should be aware that Islamic stocks' conservative features do not present a superior investment alternative, especially in economic turmoil.     

Optimal portfolio choice in the presence of domestic systemic risk: empirical evidence from stock markets

In this paper, we empirically investigate the consequences of domestic systemic risk for stock market investors. To tackle this issue, we consider two different investment strategies. One strategy is to be “crisis-conscious”, i.e., taking the possibility of systemic events into account, and the other one is to be “crisis-ignorant” and thus disregarding systemic risk. We compare the optimal portfolio choices and investment results of these strategies in an historical simulation, using almost three decades of historical stock price data. Our main findings are as follows: the crisis-conscious investor tends to choose less extreme portfolio weights for individual stocks than the ignorant investor. The overall risky investment is, however, of similar size for both. By ignoring the possibility of systemic events, the crisis-ignorant strategy performs significantly worse from the viewpoint of expected return as well as expected utility.     

Brexit and FDI

• The potential for a departure from the EU to undermine the UK's attractiveness as a location for Foreign Direct Investment (FDI) is often cited as one of the key risks were the UK to leave the EU. In weighing up the threat to FDI posed by ‘Brexit’ we assess the net gain from inward investment and the role played by EU membership in attracting FDI.
• In theory, FDI benefits the economy via lower interest rates, higher wages for workers and ‘spillover’ benefits boosting economy‐wide productivity. But the evidence for these benefits is ambiguous. And FDI has potential drawbacks. These include an adverse effect on the tradeable sector, reflected in a wider current account deficit, the potential to ‘crowd out’ investment by domestic firms and the fiscal cost of subsidies paid to inward investors.
• That almost half of FDI in the UK comes from other EU countries suggests that EU membership is not the only driver of foreign investment in the UK. Other factors include the UK's business friendly environment, as reflected in global competitiveness surveys, and a relatively deregulated labour market. Of perhaps most importance is the lure provided by the UK's large domestic economy. 80% of FDI in the UK is in sectors where sales to the EU account for less than 10% of total demand.
• However, FDI in manufacturing does look vulnerable to Brexit, given the importance of the EU market. Granted, manufacturing accounts for a modest share of UK FDI. But to the extent that FDI boosts productivity, a loss of inward investment in this sector is likely to come at a disproportionate cost.
• Our modelling suggests that in a worst case Brexit scenario, the stock of FDI could ultimately be 7% lower relative to the UK remaining in the EU, potentially knocking around ½% off the level of GDP.

A model of market-making with imperfect information

Although the prevention of false markets is one of the major concerns of stock market authorities in the UK and elsewhere, until recently, the theoretical literature on the workings of markets with imperfect information has been sparse. This paper analyses the problem of providing liquidity to investors when price-sensitive information is unequally distributed. Specifically we shall model the activities of a market-maker when certain traders have price-sensitive information unavailable to other market participants. Our model will show how the bid-asked spread would be determined in such a market. It is useful in explaining certain tactics employed by stock market traders and in suggesting alternative ways of evaluating market efficiency. The theory is developed in three sections: (1) the determination of the bid-asked spread for a single, isolated transaction; (2) the determination of the bid-asked spread in a continuous market; (3) the relationship between the spread and the size of transaction.     

Equity market contagion during the global financial crisis: Evidence from the world's eight largest economies

The global financial crisis (2007–2009) saw sharp declines in stock markets around the world, affecting both advanced and emerging markets. In this paper we test for the existence of equity market contagion originating from the US to advanced and emerging markets during the crisis period. Using a latent factor model, we provide strong evidence of contagion effects in both advanced and emerging equity markets. In the aggregate equity market indices, contagion from the US explains a large portion of the variance in stock returns in both advanced and emerging markets. However, in the financial sector indices we find less evidence of contagion than in the aggregate indices, and this is particularly the case for the advanced markets. The results suggest that contagion effects are not strongly related to high levels of global integration.

Boom time for British manufacturing investment

Andrew Sentance and Giovanni Urga review the performance of investment over the UK recovery and to date and discuss how the current upswing in investment will develop over the years ahead. By historical standards the economy as a whole is likely to see a modest investment recovery. But manufacturing industry is on the threshold of an investment boom which should see an exceptional period of growth in industrial investment.     

Identifying states of global financial market based on information flow network motifs

Stock markets exhibit different states due to internal and external shocks. It is of great significance to identify the status of global financial markets. Based on 48 global stock indices from 1996 to 2018, we constructed a global stock index transfer entropy network, which represents the information flow between stock markets in different economies. By analyzing the triadic motifs in the transfer entropy network, we divided the global stock market into different market states based on the distribution of motifs. The characteristic structure of information flow was observed in different market states. We found that the information flow in the global stock market increases significantly during major financial events, indicating that the global stock index has a mutual influence and a close relationship with each other. In addition, stock indices in the Asia-Pacific, Middle East, and Africa are the main sinks of information, while stock indices in the Americas and Europe are the primary sources of information.     

Equity Markets & the Economy

Media commentary in the New Year has seen the word ‘recession’ increasingly associated with short‐term US prospects, which seemed so positive only half a year ago. In this article, John Muellbauer 1 Muellbauer is Professor of Economics at Oxford and an Official Fellow of Nuffield College.
discusses this ‘boom to bust’ phenomenon, the role of asset prices and the wider ramifications for global growth, exchange rates and the UK economy.     

Trump versus Reagan – the global dimension

• ? Could the Trump era resemble the 1980s? ‘Reaganomics’ boosted world growth – but not necessarily in the ways people think – and not for emerging markets (EMs), a larger part of today's world economy. Growth then was also aided by factors such as declining interest rates, which are missing today, and we doubt that deregulation will lead to a productivity surge. US asset prices, meanwhile, were depressed in 1981, unlike now, so the big gains of the 1980s are unlikely to be repeated. EM assets should do better than back then, though.
• ? Optimistic observers – and to some extent, markets – have been drawing parallels between the policy mixes of the Trump and Reagan administrations, and talking up the prospects of stronger global growth. But while the US did support world growth in the 1980s, this was arguably more due to Keynesian' demand‐side policies than supply‐side ones: Reagan's record on supply‐side policies was mixed.
• ? The US is still an important driver of global activity, but markets may be too optimistic about the effect of Trump's policies on world growth. Any Trump fiscal stimulus will occur against a much less favourable background than that of the 1980s, when US growth also benefitted from a variety of factors missing now.
• ? It is also unclear whether Trump's administration will tolerate large expansions of the current account and fiscal deficits as the ‘price’ for more growth. And we are sceptical about the prospects of big gains from deregulation: US economic dynamism has waned, but the policies so far proposed in this area look potentially misdirected.
• ? Over the coming years asset market performance is unlikely to mirror that of the 1980s: valuations suggest less room for dollar appreciation and stock market gains this time around. But emerging market (EM) assets may do better – the soaring dollar and high US rates that hit EMs in the 1980s are unlikely to be repeated. And our analysis suggests even modestly better US growth will support commodity prices and EM growth.

     

Brexit and world growth – what are the risks?

• The initial global market reaction to the UK Brexit vote was very negative and in our view overdone. Nevertheless, we expect the uncertainty to linger for a while, with the vote having refocused investors on existing vulnerabilities in the world economy. Our new forecasts see the main negative impacts on growth being in the UK, the Eurozone and Japan. Risks to our new forecasts remain skewed to the downside, with a significant danger of world growth dropping below 2% this year.
• Our new forecasts see UK growth dropping to 1.4% a year in 2017–18, down from 2.2–2.3% a year before. In the Eurozone, growth will be around 0.2% a year weaker in 2017–18 and Japan is also a loser as a result of the risk aversion‐driven stronger yen, with growth at just 0.3% in 2017 from 0.5%.
• The size of the initial global market sell‐off makes no sense in the context of the likely impact from a weaker UK. In part, it seems to have reflected the pricing in of very negative scenarios in the Eurozone. But investors may also be worrying about other global problems glossed over in recent months.
• One risk to our forecast is that confidence effects on businesses and consumers are larger than we expect – but such effects are often overstated. Another danger is that more of the recent financial market weakness will ‘stick’ than our new baseline forecasts assume.
• Our world recession indicator is already at elevated levels and suggests a significant danger of world growth slipping below 2% this year; not a recession, but it might feel like one. Global policymakers need to act quickly to head off the risks.
