Recent political events have highlighted a growing anti-globalisation sentiment, evident in scepticism towards free trade and resistance to immigration. However, existing analyses focus on short-term, local effects. Using global data, this column takes account of the complex relations between trade, migration, innovation, and growth. Liberal trade and immigration stances are found to have positive effects on global output. The results suggest that globalisation remains a tremendously powerful engine of growth.

Trade agreements involving the US could be the first economic casualty of the 2016 election. The existing US trade agreements rose from the ashes of WWII and the Great Depression. This column argues that understanding how they protect the US economy, American workers, and consumers is critical to avoiding a repeat of the policy mistakes of earlier eras.

Why did so many of those who feel left behind vote for a member of the global elite in the US election? This column argues that rather than an increase in income and wealth inequality, it may be a rise in equality for wealthy African-Americans, for women, and for the gay community that is feeding a greater sense of unfairness. If we advocate greater horizontal equality, we must also ensure that it is embraced, or at least tolerated, by all.

The European Commission has just called for a fiscal stance that is more supportive of the recovery and of monetary policy in the Eurozone. This column argues that the case is strong for spending now on investment and other targeted programmes supporting growth and employment. However, fiscal space is heterogeneously distributed across the Eurozone, with some countries able to exploit a clear margin, and others needing to pursue a more prudent approach of gradual debt unwinding. A common stabilisation capacity would help for managing shocks that cannot be absorbed by national stabilisers alone.

With growth still weaker than is desirable and challenges originating from geopolitical developments further complicating the economic outlook, responsible growth-friendly fiscal policy needs to play a bigger role in supporting demand in the Eurozone today. This column presents a new European Commission Communication on Eurozone fiscal policy, which outlines what a “positive fiscal stance" for the Eurozone would look like.

The ‘gig economy’ refers to the independent workforce, including those drawing income from new digital platforms such as Uber and Airbnb. This column uses a survey of 8,000 respondents in the US, the UK, Germany, Sweden, France, and Spain to explode some myths about this relatively new and controversial side of the economy. Among the findings are that existing statistics severely underestimate the size of the gig economy, and that 30% of those working independently do not do so out of choice.

Recent studies on intergenerational income mobility have looked beyond the two-generational model to the role of grandparents, but multigenerational patterns in the wealth distribution have received less attention. This column uses a Swedish four-generational wealth dataset to study the role of family background for people’s wealth status and how much of this that is due to material inheritance. Most of the transmission in wealth status between generations comes from parents in the form of bequests and gifts, with only a marginal contribution from grandparents.

Italians will vote next month on constitutional reform that aims to abolish perfect bicameralism. The reform would reduce the size of the Senate, and make the Chamber of Deputies the primary legislative body. This column discusses the effects of perfect bicameralism on legislative efficiency and the relationship between executive and legislative power. The reform would see a reduction in decree laws and legislative decrees, and lead to less frequent use of the confidence question. Additionally, it would see important improvements in bureaucratic efficiency.

Di Maggio, Kermani, Song, 26 November 2016, 4304 reads

The Global Crisis of 2008 highlighted the role of intertwined financial markets in shaping the transmission of risk and the build-up of fragility throughout the system. This column investigates the role of dealer networks in the corporate bond market. Network relationships appear to act as a buffer in periods of distress, but also accentuate systemic fragility as connections with vulnerable dealers might affect trading outcomes even for sound dealers.

Saito, Matsuura, 25 November 2016, 7640 reads

Agglomeration’s impact on product quality has received much less attention than its impact on productivity, despite the importance of quality as a precondition for economic development. This column employs plant-product-level data from Japanese manufacturing to assess the effects of urban agglomeration on product quality. The findings suggest that state and municipal tax breaks, and other public efforts to attract enterprises, enhance economic competitiveness by improving product quality along with productivity.

Dreher, Yu, 25 November 2016, 6801 reads

The belief that educating future leaders of other countries helps spread the values of the country of study has inspired many foreign-education programmes. This column uses data on the education and UN voting patterns of 831 world leaders to show that foreign-educated leaders tend to be less friendly with former hosts, but more friendly with countries that share the host’s culture and politics. This appears to reflect a tension between ‘affinity’ with former hosts and ‘allegiance’ to domestic voters.

Buti, Bohn-Jespersen, 25 November 2016, 3958 reads

The actions taken in 2008-09 by the G20 avoided an outright depression during the financial crisis, but questions remain over its ability to evolve from a short-term crisis response forum to effectively addressing more long-term challenges. This column argues that to ‘win the peace', G20 members as well as G20 Presidencies have to redesign international economic policy coordination, and ensure that the focus is kept on a limited number of deliverables to which all G20 members can agree.

Elekdag, Gelos, 24 November 2016, 4243 reads

The relationship between corporate governance and financial stability has received little attention in the context of emerging markets. Using new firm-level indices of governance in emerging markets, this column shows that both firm-level governance and governance frameworks have generally improved at the country level over recent years. These stronger frameworks have enhanced the resilience of firms to global shocks, and bolstered balance sheets.

Landau, 24 November 2016, 8039 reads

The objectives of maximising growth and reducing external imbalances may not be fully compatible in a financially integrated and asymmetric world. This column argues that countries have two choices: they can contain global imbalances and gross financial flows through permanent capital controls, or they can pursue financial integration, managing growing imbalances and external exposures by creating more global safe assets. This implies debt contracts would be either state-contingent, with easy restructuring, or built to be ‘safe’, with a high level of commitment by the issuer.

Constâncio, Hartmann, 24 November 2016, 25157 reads

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. 

Colantone, Stanig, 23 November 2016, 11191 reads

The vote for Brexit was a watershed moment in European politics. This column investigates the causal drivers of differences in support for the Leave campaign across UK regions. Globalisation in the form of the ‘Chinese import shock’ is found to be a key driver of regional support for Brexit. The results suggest that policies are needed that help to redistribute the benefits of globalisation across society. 

Konrad, Stolper, 22 November 2016, 9191 reads

The reasons why a country would comply with international standards of transparency in the face of sizeable returns in the tax haven business are unclear. This column highlights fundamental coordination problems in the fight against offshore secrecy regimes and their implications for optimal policies, and explores whether the fight will be successful or not.

Shafik, 22 November 2016, 9690 reads

The spread of financial shocks globally has caused some to argue that capital accounts should be more closed, thereby shrinking the opportunities available to global savers and borrowers alike. That would put further downward pressure on interest rates in surplus economies, and upward pressure on borrowing costs in economies where the greatest opportunities lie. This column argues that by acting in their local interest, domestic macroprudential policymakers can safeguard against the risk of financial instability spilling across borders, while continuing to allow capital to flow to where it is of most use.

Beck, Carletti, Goldstein, 22 November 2016, 9888 reads

The Global Crisis has led to a new wave of regulation. This column argues that improved capital requirements, liquidity requirements, bank resolution and cross-border regulatory cooperation are welcome, but that unresolved problems remain. Specifically, regulation may become too complex, focus too little on macroprudential risks, be inadequate to deal with crises in global financial institutions, or fail to cope with financial innovation.

Jehiel, Lamy, 22 November 2016, 8204 reads

Bid preferences and set-asides are popular discriminatory practices in US public procurement, but are prohibited in the EU. This column argues that discrimination can be cost-reducing provided it is targeted to favour those firms whose participation is more responsive to the auction procedure. Situations when set-asides may be cost-reducing are also discussed.

Timmer, Los, Stehrer, De Vries, 21 November 2016, 10014 reads

The recent deceleration of world trade has been widely discussed, and many argue the relationship between trade and GDP growth is undergoing a fundamental shift. This column presents a novel framework to account for changes in the import intensity of global demand. Import intensity rose between 2000 and 2008 due to high demand for durables and to international production fragmentation. After 2011, fragmentation stopped and demand shifted to services, in particular in China. Low trade ratios are likely to persist in the near future.

Coelli, Moxnes, Ulltveit-Moe, 21 November 2016, 9250 reads

Free trade is under fire, with evidence documenting the distributional impacts and labour adjustment costs of trade liberalisation mounting. This column instead presents new evidence on the benefits of freer trade in terms of growth and innovation. It points to gains that could be lost if support for globalisation is not maintained.

Fontagné, Santoni, 20 November 2016, 8716 reads

A key driver of productivity is ease of resource allocation. This column uses firm-level data for France to show that misallocation has a spatial dimension: resource allocation and the associated effect on productivity are related not only to firms’ characteristics, but also to the environment in which they operate. Denser commuting zones seem to offer a better match between employers and employees, leading to more productive firms.

Bordo, Sinha, 20 November 2016, 4703 reads

In the wake of the Great Recession, the Federal Reserve took unprecedented measures to stem economic decline. This column uses the Fed’s open-market operations in 1932, another period of short-term rates near the zero lower bound, as a comparison for the QE1 operation of 2008-09. Although the 1932 policy boosted output and inflation, if the Fed had announced the operation in advance and carried it out for a full year, the Great Depression could have been attenuated considerably earlier.

Boyarchenko, Lucca, Veldkamp, 19 November 2016, 5959 reads

Information sharing has come under increased scrutiny in the context of interbank lending, foreign exchange markets, and US Treasury auctions. This column explores the benefits and drawbacks of information sharing by dealers in US Treasury auctions. Information sharing is found to benefit first and foremost the issuer, i.e. the Treasury. The model provides insight on auction revenue, risk-sharing, and the decision to bid through a dealer, with information sharing having a sizeable effect on each.

Fioramanti, Waldmann, 19 November 2016, 9275 reads

The European Commission is currently evaluating compliance with the Stability and Growth Pact across the Eurozone. However, differences in the econometric methods used by member states and by the Commission can lead to estimates that are at odds. This column argues that the Commission’s method of estimating the non-accelerating wage rate of unemployment for Eurozone members, which relies on an accelerationist Phillips curve, is inferior to specifications with a traditional Phillips curve. The findings highlight how technical aspects of an estimation procedure can have serious effects on policy outcomes.

Daly, 18 November 2016, 5959 reads

There is an increasing consensus that global ‘excess saving’ has contributed to a reduction in equilibrium real interest rates. This implies a decline in yields of all assets including, but not restricted to, government bond yields. This column argues that since the turn of the century, the global economy has also been characterised by a rise in the yields on quoted equity, a feature for which the standard excess saving story cannot easily account. A separate explanation is that an increase in the global risk premium has increased the wedge between risk-free interest rates and the real required return on risky investments. 

Balgova, Plekhanov, 18 November 2016, 5364 reads

The major increase in the volume of non-performing loans as a result of the recent financial crisis was predictable, but the persistence of this bad debt is a cause for concern. Using a sample of 100 countries, this column compares economic outcomes in three different scenarios following a rise in non-performing loans. Reducing these loans has an unambiguously positive medium-term effect, with countries that experience an influx of fresh credit growing the fastest. Allowing high levels of non-performing loans to persist, on the other hand, can cost more than two percentage points of economic growth annually.

Mody, 18 November 2016, 7812 reads

Between the first quarter of 2013 and the end of 2015, London property prices rose rapidly, the exchange rate appreciated, and the current account deficit widened. This column argues that the rise of the pound was in fact a financial bubble, riding on a property price-exchange rate carry trade.This unsustainable bubble was deflated by Brexit.

Vaitilingam, 17 November 2016, 9328 reads

It is questionable whether the lessons from the relatively new field of household finance have been reflected to any great extent in the way that the banking and financial services industry works. This column introduces the Think Forward Initiative, which seeks to build a bridge between research and action. A better understanding of how and why people spend, save, invest and hold assets can act as a springboard for action to help consumers.

Marsh, Nagly, Pagoulatos, Papaioannou, 17 November 2016, 9166 reads

It is now seven years since the Greek crisis began. As well as reflecting the chronic deficiencies of its own institutions, the failings in Greece also reflect substantial shortcomings in international institutions. This column argues that it is time for all sides to move on, and proposes a simple debt operation for Greece that can deliver debt sustainability with minimal adjustments to the ESM operating procedures.

Well-developed and efficient financial markets are important contributors to the economic growth of developing economies. Unfortunately, many low- and middle-income countries lack liquid public capital markets. This column explores the performance of stock exchanges opened since 1975 across a sample of countries. A minimum number of listings and turnover in the first five years appear to be necessary conditions for success over the first two decades. Developing countries considering opening a stock exchange should ensure that there is sufficient interest from firms and investors.

Gerlach, Stuart, 17 November 2016, 4553 reads

The ‘dot plots’ that the Federal Open Market Committee has been publishing since 2012 have attracted a great deal of attention, but are difficult to interpret because changes in them reflect a combination of new information and changes in the projections horizon. This column addresses how the Committee members’ views of monetary policy have evolved in recent years, and have they have responded to changes in the macroeconomic environment.

Caliendo, Casanova, Gorry, Slavov, 16 November 2016, 6743 reads

Not knowing when you are going to retire can make it hard to plan both savings and consumption in old age. This column examines how much uncertainty people face over their retirement and how costly this is as they attempt to make optimal saving plans. It argues that current structure of the Social Security retirement and disability programmes in the US does not provide much insurance against this uncertainty.

Bove, Elia, 16 November 2016, 6840 reads

There is much dispute over whether immigration is beneficial or detrimental to the host country, and any conclusions are often event-driven rather than evidence-based. This column explores evidence on how immigration affected economic development between 1960 and 2013 through its effect on the cultural and ethnic composition of the destination country. Cultural heterogeneity appears to have had a positive impact on economic development, and the positive effect of diversity seems to have been stronger in developing countries.

Cecchetti, Schoenholtz, 15 November 2016, 3866 reads

A growing class of mutual funds – those that hold mostly illiquid assets – appear to be a potential source of systemic risk. This column discusses why, and argues that converting open-end mutual funds into exchange-traded funds could mitigate the problem. When markets are liquid, exchange-traded funds operate like open-end mutual funds; but should markets become illiquid, exchange-traded funds then operate like closed-end funds and face no run risk.

McIntosh, Hanson, 15 November 2016, 4956 reads

At first glance, the migration pressures on the EU and US appear similar, but recent history is not a reliable guide to future trends. This column uses demographic trends to predict that the US will experience a gradual decline in its newly arrived immigrant population, while the EU, ringed by nearby high-population-growth states, will see large increases in the stock of first-generation immigrants. As a result, US emphasis on strengthening borders and returning undocumented migrants may be misplaced.

In September 2016, the ECB held its first Annual Research Conference. This column surveys the contributions to the conference, which brought together policymakers and academics from around the world to promote discussion of topics at the forefront of monetary and financial economic research. Nobel laureate Eric Maskin gave the keynote lecture, addressing whether fiscal policy should be set by politicians, and the conference included eight further presentations and a panel discussion on monetary policy and financial stability.

Almost half of all unemployed people in Europe have been looking for a job for over a year, causing considerable mental and material stress on those affected and pushing many of them to the margins of the labour market. This column introduces a new VoxEU eBook that examines patterns of long-term unemployment across key European countries and asks what measures have proven effective in helping people back into work and what more can be done.

Georgiadis, Mehl, 14 November 2016, 5197 reads

In theory, financial globalisation has ambiguous effects on monetary policy. It may dampen effectiveness, but it may also amplify it through exchange rate valuation effects. This column shows evidence that the latter effect has dominated since the 1990s. Financial globalisation has increased the output effect of a tightening in monetary policy by as much as 25%. One implication is that monetary policy transmission mechanisms have changed, with the exchange rate channel gaining importance at the expense of the interest rate channel.

Recent events have heightened concerns that central banks with private shareholders might differ in their financial behaviour from purely public central banks, perhaps focusing excessively on profits, dividends, and risks to their balance sheets. Using information on shareholding and new data on governance rules for 35 central banks, this column finds no significant difference in financial behaviour based on ownership, due, it would appear, to governance arrangements restraining policy toward private shareholders and, more generally, affecting central bank behaviour.

Questions over the value of a university education are underscored by negative student experiences. Personalised coaching is a promising, but costly, tool to improve student experiences and performance. This column presents the results from an experiment comparing coaching with lower cost ‘nudge’ interventions. While coaching led to a significant increase in average course grades, online and text message interventions had no effect. The benefits of coaching appear to derive from the trust-based nature of relationships and personalised attention.

Buyer-supplier networks in production processes play an important role in determining the pattern of shock propagations and aggregate fluctuations. This column provides empirical evidence on the structure of production networks and buyer-supplier sales comovements. A strong interdependence of sales growth is confirmed. In general, firms are more affected by their customers than suppliers.  Manufacturing and wholesale sectors exhibit higher propagation factors while retail and service sectors exhibit lower propagation factors. 

Burchardi, Chaney, Hassan, 12 November 2016, 4829 reads

The economic effects of the unprecedented levels of international migrations over the past few years are at the centre of political debates about immigration policy. This column evaluates the causal effect of migration on foreign direct investment using immigration patterns to the US going back to the 19th century. Foreign direct investment is found to follow the paths of historical migrants as much as it follows differences in productivity, tax rates, and education. The results suggest a mechanism of information flow facilitation, and that the effect of ancestry on foreign direct investment is very long-lasting.

Head, Mayer, 12 November 2016, 5805 reads

Unlike technical progress in transport or communication technologies, regional trade agreements are political decisions that can be reversed, as Brexit and the campaign promises of President-elect Donald Trump to raise tariffs on imports from Mexico demonstrate. This column analyses the consequences for the car industry of these two examples of the dismantling of an RTA. Car production would fall significantly in the UK under Brexit and in Mexico under ‘Trumpit’ due to a combination of tariff-induced sales losses and increased plant costs.

Roth, Jonung, Nowak-Lehmann, 11 November 2016, 7780 reads

The euro as a common currency has recently been the subject of harsh criticism by economists from both sides of the Atlantic, including claims that citizens in some Eurozone countries are turning against it. This column argues that, in fact, the euro currently enjoys comfortable popular support in each of the 12 original member states of the Eurozone and that potential upcoming referenda in any of these countries do not appear to pose a threat to the currency. In contrast, popular support for the euro has declined sharply in non-Eurozone EU member states since the recent crisis, with the UK standing out as the country with the most negative view. 

Dhillon, Krishnan, Patnam, Perroni, 11 November 2016, 4099 reads

The ‘curse’ of natural resources on economic development has been well documented, but there is no consensus on its underlying causes. Exploiting the formation of new Indian states in 2001, this column shows that the effects of state breakup on local economies differ systematically across natural resource-rich and resource-poor areas, in line with the spatial distribution of natural resources within states. The relationship between resource abundance and economic outcomes flows, at least in part, through a political channel.

Higuchi, Kodama, Yokoyama, 11 November 2016, 4961 reads

Studies have confirmed an increase in earnings inequality in Japan, but do not agree on how or when it increased, or which groups were most affected. This column decomposes changes in earnings data to show a recent decrease in the returns to general human capital of almost all Japanese workers, at the same time as an increase in the returns to firm-specific human capital among male workers with high wage rates. Gender-based wage inequality has persisted.

Valero, Van Reenen, 10 November 2016, 11319 reads

Growth in higher education has been driven by the view that human capital is essential for economic and social progress. This column uses a comprehensive international dataset covering 78 countries to show that on average, a 10% increase in the number of universities (roughly adding one more university to the average region in the data) increases a region’s income by 0.4%, with additional effects spilling over to other regions within the same country. In the UK context, the benefits of university expansion are likely to far outweigh the costs.

Baghai, Becker, 10 November 2016, 6123 reads

Excessively high credit ratings are thought to have contributed to the Global Crisis. A key concern is the conflict of interest that arises due to rating agencies being mainly paid by the companies whose securities they rate. This column uses Indian data to explore how the commercial ties between issuers and raters affect ratings. The results indicate a fee-driven conflict of interest, with an upward bias in the ratings of issuers whose fees are important to an agency. This highlights the potential benefits for the financial system of circumscribing rating agency consulting.

A recent report by the German Council of Economic Experts argues that the current monetary policy of the ECB is no longer appropriate and is masking structural problems in Eurozone countries. The November 2016 Centre for Macroeconomics and CEPR expert survey invited views on the report. More than three-quarters of respondents disagree that ECB monetary policy should become less accommodating, and respondents also disagree that ECB policy is masking structural reforms. The panel is divided, however, on whether ECB policy is making implementation of structural reforms less likely.

In recent years, the use of randomised controlled trials has spread from labour market and welfare programme evaluation to other areas of economics, and to other social sciences, perhaps most prominently in development and health economics. This column argues that some of the popularity of such trials rests on misunderstandings about what they are capable of accomplishing, and cautions against simple extrapolations from trials to other contexts.

Household micro-data reveal striking differences in secured debt holdings across Eurozone countries. This column presents new evidence on the role of household characteristics and country institutions in accounting for the cross-country patterns observed. In countries with lengthier asset repossession periods, young or low-income households face higher borrowing costs, leading to a lower probability of holding mortgages.

The Chinese Shanghai Stock Exchange Composite Index dropped by a third in mid-2015, wiping out billions in share value. One of the responses of the Chinese government was to directly participate in the stock market. This column assesses the costs and benefits of this intervention, finding that the resulting gains amounted to about 5% of Chinese GDP. The value was created not just from increased equity and investor confidence, but also from increased liquidity and reduced probability of default for listed firms.

After the 2008 Global Crisis, there has been progress towards a system-wide regulatory architecture that includes a national macroprudential authority. This column describes a ‘capacity indicator’ that measures the state of macroprudential policies worldwide, including the features policymakers believe constitute a successful macroprudential policy regime. Eventually this index may be used to establish whether these macroprudential policy innovations have been successful.

The percentage of people living in extreme poverty around the world has fallen by more than half over the past three decades. But polls show that most people are not only ignorant of this fact, but believe that poverty has increased. This column explores progress towards ending global poverty by 2030, the first of the UN’s Sustainable Development Goals. Poverty figures have fallen around the world since 1990, and there is a broad consensus on the policies needed for further reductions. Eradicating global poverty is achievable, but it is dependent on global and domestic political cooperation.

The transportation revolution of the 19th century opened up new opportunities for migrant and tourist travel across the North Atlantic. While the impact of this revolution on freight cargoes and, to some extent, mass immigration has been well documented, we know considerably less about non-migrant overseas passenger travel. This column presents data on first class ocean travel fares between the US and the UK from 1826 to 1914, and demonstrates how such data can be gathered from various scattered sources and compiled into a reasonably reliable, representative, and informative long-term time series.

Ito, Reguant, 06 November 2016, 4232 reads

In deregulated electricity markets, producers and consumers participate in auctions in forward and spot markets (‘sequential markets’) which determine the allocation of electricity production. This column asks whether financial traders should be allowed to participate in electricity markets to arbitrage a price difference between forward and spot markets. Creating a sequential market is likely to improve market efficiency and consumer welfare, and arbitrage by financial traders is likely to benefit consumers by lowering electricity prices, but from a social planner's point of view, arbitrage does not necessarily improve market efficiency.

Marinescu, Wolthoff, 06 November 2016, 14491 reads

One of the fundamental questions in labour economics is why some workers are paid more than others within the same industry. This column uses data from adverts on a large US job website to investigate what's behind these wage differences. The job titles used in adverts capture more variation between jobs than standard occupational classifications. By failing to recognise this, the previous literature has attributed too much of wage inequality to luck and too little to differences in worker and firm characteristics.

Cestone, Fumagalli, Kramarz, Pica, 05 November 2016, 5272 reads

Diversified business groups and conglomerates have been shown to withstand economic shocks better than equivalent standalone companies. This column uses employment data from France to argue that business groups use internal labour markets to save on termination, search, and training costs, which helps them cope with unexpected changes. These internal markets also provide implicit employment insurance to employees.

Tax evasion imposes substantial costs on economies around the world. Beyond equity concerns, it erodes the tax base, with indirect effects on public investment and service provision. This column uses a model calibrated on the Italian economy to assess the direct and indirect effects of tax evasion on economic growth. Enforcing taxes would force small businesses to innovate, putting pressure on larger businesses and clearing the market of poorly performing small firms. Tackling tax evasion is thus important not only for equity reasons, but also for efficiency.

With structural reforms of labour markets currently being considered in several countries, including in southern Europe, assessing their impact is vital. This column investigates the effects of employment protection legislation on a variety of production factors. Structural reforms that increase labour flexibility – that is, which weaken employment protection legislation – could have a favourable impact on firms’ R&D investment and their hiring of low-skilled workers.

Economists normally study wealth formation and inequality among the adult population, but some people already possess economic resources in early childhood. This column uses data from Denmark to examine childhood wealth and the role of wealth transfers early in life. A main result is that wealth inequality starts as early as childhood. Although overall wealth levels in childhood are low, they are better predictors of wealth in adulthood than parental wealth.

Huang, Pagano, Panizza, 03 November 2016, 5937 reads

High levels of public debt are correlated with lower economic growth across countries, but questions remain about whether this relationship is causal. Using Chinese data, this column explores whether increasing public debt crowds out private investment. City-level investment ratios are found to be negatively correlated with local government debt for private manufacturing firms, but not for state-owned or foreign-owned manufacturers. This suggests that as well as the short-term benefits of fiscal stimulus, there might also be negative longer-term effects, such as the crowding out of more efficient firms.

Over the past two years, a significant disinflationary impulse has dampened nominal activity around the world. As this disinflationary impulse fades, however, both nominal and real growth should normalise. Indeed, as this column highlights, the latest signs show inflation and inflation expectations rising, profits stabilising, and capital expenditure inching up.

Furman, 02 November 2016, 27845 reads

The landscape of the fiscal policy debate has changed over the past decade, with academics and international organisations moving away from an ‘Old View’ of fiscal policy as ineffective.
