The sluggish growth of the US economy after the 2014-2016 decline in the oil price surprised many economists. This column argues that it should have been expected. The modest stimulus to private consumption and non-oil business investment was largely offset by a large decline in investment by the oil sector. Growth was further slowed by a simultaneous global economic slowdown, reflected in lower US exports.

Since the Global Crisis, private credit has risen sharply in several emerging market and developing economies as well as advanced economies. This column examines the role of investment alongside these credit booms, and how output growth has been affected. These booms have been unusually ‘investment-less’ in comparison to previous episodes, which were accompanied by investment surges. The absence of investment surges during credit booms is accompanied by lower growth, especially once the credit boom unwinds.

While the impact of modern technological change on the skill premium has been well explained, there has been no study of the evolution of the skill premium over the very long run. This column reveals that the skill premium in Western Europe declined between 1300 and 1600, and converged to a low and stable level afterwards. Growth and technological change, while stimulating economic development and the transition from a pre-modern era to modern era, reduced wage inequality between different working groups.

Investment growth in emerging market and developing economies has slowed sharply since 2010. This column argues that this slowdown reflects a range of factors, including negative terms-of-trade shocks, slowing FDI inflows, weak activity, and rising private debt burdens and political risk. Policymakers can boost investment directly through public investment, and indirectly by taking measures to improve overall growth prospects and the business climate.

Corporate saving has increased relative to GDP and corporate investment across the world over the past three decades, reflecting how the global decline in the labour has led to increased corporate profits. This column characterises these trends using national income accounts and firm-level data, and relates them to firm characteristics and the accumulation of financial assets. In response to declines in the components of the cost of capital, a model with capital market imperfections generates an increase in corporate saving similar to that found in the data.

We are living in a world in which banks are large relative to the economies they serve. This column uses comprehensive data on Japanese banks from 1990 to 2010 to examine how the fates of individual banks matter for aggregate performance. Much of the fluctuation in Japanese aggregate investment appears to be driven by the idiosyncratic successes and failures of a limited number of institutions, and there is good reason to believe that the situation is similar in many developed countries.

In July, G20 trade ministers adopted nine 'Guiding Principles for Global Investment Policymaking'. This column introduces the latest GTA report, which shows how well the G20’s track record stacks up against these new growth-promoting goals.

The relationship between taxation and economic growth is complex, and relies in large part on the efficiency with which taxes are used. This column examines the impact of corruption on this relationship. The boost to welfare from reducing corruption is substantially larger than the marginal gains from optimising the tax rate for an existing level of government efficiency.

The Latin American and Caribbean region is trapped in a vicious cycle of low savings and poor use of these savings. This column describes how this problem is reinforced by the current financial system, and prescribes three remedies to policymakers and households to break the cycle. The government should create a better environment for saving and develop a better financial system, but it should also tackle investment distortions and fix broken pension systems. Meanwhile, a change in saving culture should be encouraged from the ground up, with financial education offered to citizens early on in their lives.

Growth in the number of publicly quoted companies is a key driver of economic development, so the apparent decline in the number of company listings, at least in developed markets, is naturally worrying for investors, exchanges, and regulators alike. This column provides a framework to address this decline, and proposes possible remedies that could be taken to encourage more listings. The listings ecosystem must establish a new equilibrium to address the evolving conflicts of interest between founders, early investors, underwriters, and future shareholders.

Finance plays a key role in growth by connecting savers and investors, but it can also be a source of crises. This column discusses whether there has been enough finance to enable productive investments. UK non-financial companies appear to have enough internal funds to cover all their investment taken as a whole, but the evidence suggests that small firms face shortfalls. The column also pleads for the development of new and better data sources to help measure the supply of finance that can be used to exploit productive investment opportunities.

Many advanced economies have experienced a productivity slowdown in recent years. Italy, however, has been experiencing such a slowdown since the mid-1990s. This column provides a detailed analysis of Italy’s patterns of misallocation over this period. Firms in the Northern regions, as well as large firms, have experienced the sharpest increase in resource misallocation. To tackle the resulting productivity slowdown, reforms need to address unemployment benefits and higher education, as well as encouraging investment in intangible assets.

Theoretical corrections of price deviations in trade are not reflected in empirical evidence. This is surprising because institutional investors should be able be able to identify mispricing. This column explores how the organisation of the asset management industry may hamper trading against mispricing. Asset managers that are less subject to redemption risk exhibit a higher propensity to trade against mispricing. Organisational structures lowering the sensitivity of investor flows to performance strengthen asset managers’ incentives to trade against mispricing.

Economic theory offers conflicting perspectives on the relationship between insider trading and innovation. To date, the empirical evidence is similarly inconclusive. This column exploits the staggered enforcement of inside trading laws across countries to explore the effect on patenting behaviour. The findings point to a robust positive effect of enforcement on various measures of patenting behaviour. Legal systems that protect outside investors from corporate insiders thus help to foster innovation.

Research and development investment is a major driving force behind innovation and economic growth. Policy measures that aim to boost innovation activities attempt to improve incentives for these investments. This column reports on recent research showing that a firm’s financial strength is strongly correlated with the firm’s expected return to research and development, and therefore has a substantial impact on its research and development investment decision.

Through the Eurozone rescue mechanisms, Germany provided the periphery with hundreds of billions in debt at very low rates. There is a widely held notion that these savings would have been better used at home. This column challenges this notion, presenting evidence that Germany’s net asset position held up well, remaining much higher than domestic returns. The main reason is that Germany’s part in the rescue operations was actually much smaller than its claims towards the periphery.

While some of the costs of climate change won’t be incurred for centuries, the actions to mitigate them need to be taken today. Over such a long timespan, small changes in discount rates can drastically change the attractiveness of such investments. This column presents estimates of appropriate discount rates for very long time horizons. The long-run discount rate for one important risky asset class – real estate – is estimated at 2.6%. This provides an upper bound on long-run discount rates for climate change abatement, one that is substantially lower than some of the rates currently being employed.

Few economists understate the importance of emerging market economies in terms of world GDP and global growth prospects. This column asks where the future of emerging markets’ investments lie. Where investors have focused in the past and institutional path dependency are important determinants of emerging markets’ allocation of international investment portfolios. This has implications for the geographical distribution of emerging markets’ portfolio investments, a force to reckon with in international financial markets.

In the wake of the Global Crisis, emerging Europe has experienced a sharp drop in investment levels. As a result, income convergence has virtually come to a halt. This column presents key findings of the EBRD’s latest Transition Report, urging countries in emerging Europe to rebalance their financial systems in order to reignite economic growth. Rebalancing is necessary in terms of the available debt–equity mix, the currency composition of credit, banks’ funding sources, and cross-border investment partners.

The growth of the asset management industry has raised concerns about its potential impacts on financial stability. This column assesses the systemic risk created by fund managers’ incentive problems and a first-mover advantage for end investors. Fund flows and fund ownership affect asset prices, and fund managers’ behaviour can amplify risks. This lends support to the expansion and strengthening of industry oversight, both at the individual fund and market levels.
