This column presents the latest Geneva Report on the World Economy, in which the authors argue that central banks can do more to stimulate economies and restore full employment when nominal interest rates are near zero. Quantitative easing and negative interest rates have had beneficial effects so far and can be used more aggressively, and the lower bound constraint can be mitigated by modestly raising inflation targets.

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.
Growing inequality has been one of the most pressing political issues since the Great Recession. However, there is a relative lack of consensus on the significant drivers of this trend. This column investigates the contribution of globalisation, via international trade, to US inequality. Although trade is found to have had important effects on certain parts of the US labour market in the early 2000s, the growth in US inequality since 1980 can be traced back to Reagan-era tax cuts.
The ECB’s 2016 Sintra Forum on Central Banking focused on the international monetary and financial system. In this column, the organisers of the forum highlight some of the main points from the discussions, including concerns that the world economy may be suffering from a shortage of safe assets and proposals for which areas international regulatory reforms should be further developed.
A popular notion is that computer automation leads to major job losses. However, this ignores the dynamic economic responses that involve both changing demand and inter-occupation substitution. Using US data, this column explores the effect of automation on employment growth for detailed occupational categories. Computer-using occupations have had greater job growth to date, while those using few computers suffer greater computer-related losses. The real challenge posed by automation is developing a workforce with the skills to use new technologies.
Britain’s decision to leave the EU surprised many. This column examines the relationship between economic prosperity and voting behaviour in the referendum. The regions that have benefitted most from immigration and trade voted most strongly in favour of remaining, while the regions where people feel most threatened voted to leave. In other countries fearing a similar EU exit, economic policy should aim to ensure that the gains from trade and immigration are as widespread as possible.
The Great Recession has had long-lasting effects on credit markets, employment, and output. This column combines a model with macroeconomic data to measure how the recession has changed beliefs about the possibility of future crises. According to the model, the estimated change in sentiment correlates with economic activity. A short-lived financial crisis can trigger long-lived shifts in expectations, which in turn can trigger secular stagnation.
The concept of 'secular stagnation' asserts that unemployment remains high and output below potential because investors are pessimistic. This column presents a way to rethink the IS-LM model to include investor expectations. This 'IS-LM-NAC' model explains the slow recovery from the Great Recession, provides a theory-consistent explanation for secular stagnation, and suggests policy options to escape it.
Since the turn of the century, income inequality has risen to be among the most prominent policy issues of our time. This column looks at inequality trends in recent decades. While relative global inequality has fallen, insufficient economic convergence, together with substantial growth in per capita incomes, has resulted in increased absolute inequality since the mid-1970s. The inclusivity aspect of growth is now more imperative than ever.
Reinhard Selten, co-recipient of the 1994 Nobel Memorial Prize in Economic Sciences, passed away in August. This column outlines the intellectual life and career of a pioneering analyst of strategic interaction of both fully rational players (game theory) and real human beings with ‘bounded rationality’ (experimental economics). Selten called himself a ‘methodological dualist’, making a sharp distinction between normative game theory and descriptive theories of social and economic interaction. Nobody else has made such substantial and important contributions to both lines of research.
Discussions about inequality tend to focus on the distribution of income and wealth. This column argues for a shift in focus towards another source of inequality – subjective wellbeing. Wellbeing inequality has grown significantly for the world as a whole and in eight of the ten global regions. One way to address this inequality is to increase social trust.
Mortgage delinquencies and foreclosures have serious implications, not just for the households affected, but for the financial stability of the economy. The solvency of the mortgage lenders is affected, and their ability to extend credit. This column identifies three key drivers of delinquency and foreclosure rates in the UK – the debt service ratio, the proportion of homes in negative equity, and the unemployment rate – and compares the rates with those in the US. It also discusses the data constraints that have hindered previous analyses.
Some economists see helicopter money as a free lunch, because it can prompt growth without requiring higher debt financing. This column argues that if there are costs associated with the permanent injection of cash into the economy, they would diminish its effectiveness.
China’s one-child policy and a general preference for sons increased competition among grooms, whose families typically bear marriage expenses. This is believed to have increased household saving in the country. This column explores whether the same is observed in other countries with unbalanced sex ratios. Premarital sex ratios are found to have a significant impact on household saving rates in India and Korea, with the direction of the effect dependent on whether the bride’s (India) or groom’s (Korea) family is typically expected to bear the brunt of marriage-related expenses.
Historians and economists generally identify two periods of trade globalisation, the first beginning around 1870 and the second during the 1970s. The column argues that new data from 1827 onwards shows globalisation beginning as trade barriers were lowered around 1840, and that both periods of globalisation were surprisingly fuelled by a regionalisation of world trade. If globalisation continues to grow in future, regionalisation may decline.
Previous research found that income and wealth inequality had little impact on the aggregate dynamics of consumption, investment and output. This reinforced the idea that we can study downturns in the economy using representative agents. This column argues that household inequality affects both the depth of a recession and the welfare losses of those affected by it. Therefore we should explicitly measure and model household heterogeneity when we consider the impact of business cycle fluctuations and the welfare consequences of economic crises.
Today's unconventional central bank policies have historical precedent. One example is the suspension of convertibility of banknotes into gold by the Bank of England between 1797 and 1821. This column argues that, although there were important differences between then and now, it demonstrates that bank reputation and interaction between bank and state are vital to the success of unconventional policies. Also, short-term unconventional policies may persist long after a crisis has passed.
Argentina and Brazil began to open their markets to the world significantly – but only partially – in the 1990s. Yet these countries’ efforts to liberalise beyond their Latin American trading partners have stalled since 1995. This column re-examines the 1990s MERCOSUR experience and raises questions over just how much trade policy cooperation these two countries have undertaken. This lack of coordination also has implications for the ‘building blocks’ versus ‘stumbling blocks’ debate in trade policy.
The Global Crisis has raised concerns over how far ‘lender of last resort’ policies by central banks should go. This column examines the history of the development of these policies throughout the world. Last resort lending is a locus of political power, and as such, its creation should be viewed as the outcome of a political bargain. It is therefore not surprising that countries differed in their propensity to create such policies, and in the powers with which they chose to endow them.
The Eurozone Crisis has taken a significant toll – both economic and political – on EU member states as well as the Union as a whole. This column identifies three elements that are key to a working solution for continued union: overcoming the intergovernmental method that has dominated EU decision‑making since the crisis, avoiding the seemingly easy route of blaming all evils on ‘Brussels’, and a more unified external representation in global economic governance.
The spillover effects of a fiscal stimulus in normal times are likely to be small, at best. This column argues, however, that when interest rates are stuck at the zero lower bound and monetary policy does not offset the expansion, public investment in surplus countries could have significant positive GDP spillovers to the rest of the Eurozone. Given current low borrowing costs, the increase in government debt for surplus countries would be modest, while debt ratios in the rest of the Eurozone could be improved.
Commodity price convergence is often seen as the best way to measure the integration of markets that defines globalisation. This column reviews research on historical prices and also presents intranational evidence from Sweden from 1732 to 1914. Price convergence appears to date to the 18th century, well before the adoption of the telegraph or the railway. For emerging economies today, intranational price convergence arising from declining internal distance effects may be a precursor to globalisation.
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 Scandinavian model of social welfare is often contrasted favourably with the US model in terms of promoting social mobility across generations. This column investigates the accuracy of these claims, focusing on the case of Denmark. Denmark invests heavily in child development, but then undoes the beneficial effects by providing weak labour market incentives for its children to attend school compared to the US. This helps explain why the influence of family background on educational attainment is similar in the two countries.
The ECB is under fire from all sides for its inability to stimulate Europe's economies. This column puts the case for an informal European ‘praesidium’ within the Eurogroup to coordinate wider stimulus and reform measures. This will inevitably lead to the appointment of a European finance minister – the Eurozone's equivalent of Alexander Hamilton, the first Treasury Secretary in the history of the US.
China’s debt – in particular its corporate debt – is large by historical and international standards. This column argues that of greater concern is the sharp increase in recent years, and that the vulnerability is heightened by the concentration of this debt in old industries that suffer from overcapacity and weak competitiveness. The authorities appear to be only now taking steps to halt the rise in corporate debt, but as prior episodes of banking crises show, this is unlikely to be enough to avert either a prolonged period of slowing growth or a financial crisis in the medium term.
The Eurozone's sustained rise in youth unemployment since 2008 threatens to create a 'lost generation'. This column presents evidence that this is, in part, an unintended consequence of pension reforms in southern Europe that locked in older workers. In future, reforms that create flexible retirement ages alongside variable pension levels could minimise the impact on youth unemployment without increasing the state's long-term pension liabilities.
When Mario Draghi famously declared that the ECB was “ready to do whatever it takes to preserve the euro”, he also specified “within our mandate”. This column examines the institutional limitations to central bankers’ actions. It argues that institutional constraints are essential in determining the sustainability of monetary policies, and hence central banks’ ability to pursue their targets. The weakness of the Bank of England in the heyday of the gold standard is a case in point.
Evidence suggests that many forms of gender inequality are higher in countries where the language distinguishes gender. But these patterns could arise spuriously, as languages and other cultural institutions have co-evolved throughout history. This column uses an epidemiological approach to isolate language from other cultural forces and provide direct evidence on whether language matters. The findings suggest how gender roles have been shaped, how they are perpetuated, and, ultimately, how they can be changed.
A common explanation for the growth in unemployment in southern Europe after the Great Recession is lack of flexibility in over-regulated labour markets. This column examines wage adjustment in regulated and unregulated labour markets in Italy during the recent crisis. Using data on immigrant workers, it shows that before the crisis wages in the formal and informal sectors moved in parallel. During the crisis, however, formal wages did not adjust downwards, while informal labour wages did. Greater flexibility in wages in the formal market could slow the decline in employment.
Determining which risks are worth taking is one of the key problems facing financial market participants. Central to this is the time-varying nature of volatility. This column examines the Chicago Board Options Exchange volatility index, VIX, which has become the standard measure of volatility risk. Complementary approaches to pricing VIX derivatives are considered, and the tumultuous economy since the Great Recession is used to assess the empirical performance of the different models.
Amid a persistent fall in oil prices, many oil-exporting countries are realising that economic diversification should be a top priority. One important pathway is to create a dynamic export sector. This column argues the standard policy of structural reforms – which mostly tackle ‘government failures’ rather than ‘market failures’ – are not sufficient. The state needs to intervene to change the incentive structure of firms and workers, and impose a strict accountability framework.
Trade economists routinely evaluate changes in consumer welfare due to trade based on the assumption of a representative consumer. This column argues that this assumption often disguises much of the heterogeneity in gains across the income distribution, which leads to an overestimation of the gains for the poor and underestimation for the rich, especially for developing countries. This could help explain the lack of public consensus on the benefits of recent free trade agreements.
Spain implemented a host of structural reforms following the Global Crisis. But questions remain about whether the current economic condition is due to the reforms or to ‘automatic’ adjustment in public and private sectors. This column sheds light on these questions by examining changes in a set of economic indicators following the introduction of the reforms. Five stylised facts are presented that suggest limitations of the reforms. Much of the current climate appears to reflect inherent limitations of the Spanish economy.
Investment officers are often the highest-paid individuals in institutions such as pension funds and foundations, because of the size and importance of the decisions they make. This column argues that successful investment officers earn their pay, because they make returns that can't be explained by luck alone. Therefore, institutional investors might benefit from investing in high-quality investment officers.
Structural reforms can have adverse effects in the short run if implemented under weak macroeconomic conditions. This column argues that prioritising reform measures that bring short-term benefits even in a bad conjuncture, and packaging them to benefit from reform complementarities across product and labour markets, remains the most promising growth strategy, especially in the post-Global Crisis context
During political campaigns, candidates often set their sights on CEO compensation as a target for potential regulation. This column considers the various arguments for regulating CEO pay and questions whether it is a legitimate target for political intervention. Some arguments for regulation are shown to be erroneous, and some previous interventions are shown to have failed. While regulation can address the symptoms, only independent boards and large shareholders can solve the underlying problems.
Structural reform and deregulation are often promoted as ways to lower barriers to market entry. The Dixit-Stiglitz model provides an important benchmark – given specific preferences, there is a constrained-optimal amount of producer entry and product variety. This column reconsiders optimality of product creation, differentiating between consumer-producer and intertemporal inefficiencies and quantifying the welfare costs of inefficient entry. Monopoly profits should be preserved when product variety is endogenously determined by firm entry, as they play a crucial role in generating the welfare-maximising level of product variety in equilibrium.
Models that estimate optimal inflation rates struggle to accurately account for interest rates reaching the zero lower bound, due to the lack of historical data available. This column suggests periods of hitting the zero lower bound are longer than previously thought, and models the optimal inflation rate target on this. Given the uncertainty associated with measuring the historical frequency and duration of such episodes, the wide range of plausible optimal inflation rates implies that any inflation targets should be treated with caution.
Household consumption can be influenced by the consumption behaviour of peers. This column examines why this is the case, and considers some policy implications. The tendency for individuals to under-save (or over-borrow) in an attempt to ‘keep up with the Joneses’ appears to be driven by the average consumption of their peers, rather than by the consumption of conspicuous items. If tax policy fails to consider these peer effects, it risks wrongly estimating the effects of tax reforms that target certain groups.
Different survey methodologies are typically employed to produce estimates of global hunger. This column considers some of the methodological issues that arise. Short reference periods for each household lead to overstated variances and the confounding of chronic and transient welfare components. The column goes on to present a new approach to measuring chronic hunger which tackles this sampling problem by employing an intra-year panel.
The separation of ownership and control for public firms may lead to fully dispersed ownership where no shareholder has an incentive to engage in governance. This column argues that blockholders (owners of large stakes) play a critical role in long-term governance, partly through a credible threat to sell their stakes. This threat is undermined by well-intentioned policy moves to create holding-period incentives and requirements. If they succeed, these policies will make exit less likely and blockholders will lose a method to discipline managers.
EU regional policies aim to lead regions onto a path of self-sustaining growth. Fully successful interventions should imply a higher growth rate, not only during the treatment (when the region benefits from the transfers), but also after the expiry of the programme (when the financing terminates). This column uses evidence from the Abruzzi region in Southern Italy to document that when the party is over and the funding ends, growth may slow down significantly.
The US health insurance market is becoming less competitive due to mergers and withdrawal of services from certain states. This column examines how this affects consumers through insurance premiums and hospital reimbursement rates. Using employer-sponsored insurance data from California, it finds that the relationship between insurer competition and health care spending depends on institutional and market structure. If premiums can be constrained through effective regulation or negotiation, then reduced competition might lead to lower costs. Absent such constraints, consumers will likely be harmed.
There has been renewed interest in economic analysis of the EU budget following the Global Crisis. This column presents new calculations of cross-border flows operated through the EU budget and compares them with those estimated for the US. For each euro paid by an average net (EU member state) contributor, approximately 75 cents return through the EU budget, and 25 cents cross a border. At the margin, the US federal budget is less redistributive in normal times, with around 90 cents per dollar returning to the contributing state, but net cross-border fiscal flows in the US increased steeply in the wake of the Global Crisis, financed by federal borrowing.
Against a background of persistently weak growth and low inflation expectations, a number of central banks have implemented negative interest rate policies over the past few years. This column argues that such policies could help provide additional monetary policy stimulus, as long as policy interest rates are only modestly negative and do not stay negative for too long to avoid adverse effects on the financial sector. While these policies do have a place in the policymaker’s toolkit, they need to be handled with care to secure their benefits while mitigating risks.
Despite ample research on the effects of minimum wage increases on employment, there has been little consensus on the effects of such increases on workers’ broader welfare, and in particular on their health and that of their families. This column analyses comprehensive data from the US on the effects of minimum wage increases on the health of children born to low-income workers. It finds that the increases have a significant positive impact on birth weights. This has important policy implications, with infant health acting as a reliable indicator of future health.
As long as countries strive to reallocate aggregate demand in their own favour, disputes will arise regarding the degree to which currency values are 'fair'. This column argues that the Penn effect – the observation that the price level is higher in countries with higher per capita income – may not be a reliable method to discern the fair value of a currency. Different specifications and different datasets lead to different estimates of the degree of misalignment, for example for the Chinese renminbi.
The Eurozone lacks a safe asset that is provided by the region as a whole. This column highlights why and how European Safe Bonds, a union-wide safe asset without joint liability, would resolve this problem, and outlines steps to put them into practice. For given sovereign default probabilities, these bonds would be as safe as German bunds and would approximately double the supply of euro safe assets. Moreover, owing to general equilibrium effects, they would weaken the diabolic loop between sovereign risk and bank risk.
The rise of peer to peer (P2P) fundraising – soliciting donations on behalf of a charity for undertaking an activity – has paralleled the growth of online social networks, but the incentives driving online donation behaviour are still poorly understood. This column examines giving behaviour for a large sample of P2P fundraising projects that individuals promoted to their Facebook friends. A negative relationship is found between the number of friends and donation size. The findings suggest a ‘relational altruism’ motive, where donors give because they care about the person who is raising the money.
