The Global Crisis has shaken the consensus on how to run macroeconomic policy. Three years ago, the authors discussed this issue on This column takes a more granular look at new efforts to rethink macroeconomic policy. It takes stock of early results and provides a more detailed agenda for the key issues that should keep policymakers and academic macroeconomists busy in the next few years.

France has a raft of labour-market regulations that kick in for firms with 50 workers or more. This column uses this threshold to identify the economic effects of size-contingent regulations. Such policies seem to subsidise small firms at the expense of larger firms. But since small firms are on average less productive than large firms, the French economy loses out.

Trade theory is ten years into the ‘new new trade theory’ revolution. This column reviews the new thinking and how it shifted thinking from why nations trade to why firms trade. This opened the door to documenting the impact of firm-level changes on industry productivity and national welfare.

What do macroeconomic shocks do to public and private saving? This column argues that it is only truly dramatic shocks that have a long-lasting effect on saving behaviour. Past crises tend to increase savings among households, but they also lead to decreased public-sector saving. However, the evidence suggests that this decrease in public saving is about a third of the magnitude than the corresponding increase in household saving.

Cross-country inequality is persistent. This column draws on economic history to explain the mechanisms by which dramatic cross-country differences in income emerge. We can reduce inequality through policies that facilitate the penetration of new technologies in poor and middle-income countries. Such policies can go a long way towards reducing existing cross-country income disparities.

Exporting is essential for economic development. But can firms move from local sales to export sales? How do firms prepare for exporting? This column presents new research showing that worker mobility is an important mechanism by which exporter knowledge spreads through the economy.

Berman, Felter, Shapiro, Troland, 26 May 2013, 18453 reads

Can foreign aid help countries emerge from civil war? This paper presents new research that suggests that injecting lots of money into conflict zones may in fact encourage corruption and violence. The aid community should focus on what it can do well: working closely with communities to target small-scale, modest improvements that can be implemented in conflict zones. If accompanied by a gradual improvement in the quality of governance, current aid recipients can aspire to a long-run improvement in both security and prosperity.

Greenwood, Kircher, Santos, Tertilt, 25 May 2013, 15814 reads

How can we accurately model the African HIV/AIDS epidemic? This column presents new research that uses computational general equilibrium models to map the spread of HIV/AIDS. Emphasising the importance of understanding behavioural adjustments and equilibrium effects, this new way of modelling the epidemic may well prove a useful tool for further research.

Ball, 23 May 2013, 76684 reads

Since the double-digit inflation of the 1970s, central banks have sought to reduce inflation and keep it low. This column argues that recent history teaches us that inflation has fallen too low. Raising inflation targets to 4% would have little cost, and it would make it easier for central banks to end future recessions.

D'Alessio, Gambacorta, Ilardi, 24 May 2013, 40604 reads

The ECB’s recent survey on household finances and consumption threw up some unexpected results – counter-intuitively, the average German household has less wealth than the average Mediterranean household. In line with a recent contribution from De Grauwe and Ji, this article analyses the principal differences in wealth and income between the main Eurozone countries.

Acharya, Steffen, 23 May 2013, 43221 reads

A pernicious aspect of the Eurozone crisis is the ‘doom loop’ linking European banks and governments. This column argues that poor European policy choices in the wake of the 2008 Global Crisis worsened the problem. Rather than being forcefully recapitalised as in the US and UK, many Eurozone banks were left undercapitalised and free to gamble for redemption. In what may be the greatest carry trade ever, they borrowed cheap, first in short-term debt markets and then from the ECB, to invest in high-yield but risky sovereign debt. Substantial bank recapitalisations against sovereign-bond losses is the way forward.

Duggan, Rahardja, Varela, 22 May 2013, 15304 reads

The ‘manufacturing matters’ movement has gained prominence on the policy agenda even as the nature of manufacturing continues to morph. This column discusses new research showing that opening service sectors to competition and foreign direct investment can be a powerful conduit for productivity gains in manufacturing. The gains depend on both the types of reforms and the specific services sectors in which these are implemented.

Canuto, Cavallari, 21 May 2013, 21678 reads

The global financial crisis has shattered the confidence of many established principles of monetary policy and financial supervision. This column argues that the two should not remain separate, and maps out the major challenges faced by their complementary implementation.

Danielsson, 21 May 2013, 53776 reads

Icelandic voters recently ejected its post-Crisis government – a government that successfully avoided economic collapse when the odds were stacked against it. The new government comprises the same parties that were originally responsible for the Crisis. What’s going on? This column argues that this switch is, in fact, logical given the outgoing government’s mishandling of the economy and their deference towards foreign creditors.

Reichlin, Turner, Woodford, 20 May 2013, 72066 reads

With persistently weak economic conditions becoming the norm in Europe, economists are considering increasingly unconventional policy options. One tool that has yet to be taken out of storage is ‘helicopter money’, i.e. the overt monetary financing of government deficits. This column recounts a policy debate on helicopter money that was held at LBS in April 2013 among three of the world’s leading monetary economists.

Hall, Sargent, 19 May 2013, 16105 reads

Can we learn from previous instances of fiscal prioritisation? This column surveys the US Treasury’s response to three wars – the Revolutionary War, The War of 1812 and the Civil War. Contemporary advocates of engaging in fiscal discrimination might ponder the actions of previous US Presidents Madison and Grant, who honoured all existing federal obligations despite challenging fiscal conditions.

Desmet, Parente, 18 May 2013, 18827 reads

Innovation is the beating heart of modern growth. This column argues that innovation-blocking institutions weaken when markets expand and competition intensifies. The rise and decline of medieval Italian crafts guilds offer valuable insights into this process. Policies that promote greater market integration and stronger competition are key steps in lowering the barriers to innovation.

Kerr, 17 May 2013, 14170 reads

Do economies’ social policies affect their innovative outcomes? This column uses the case of venture capital investors to argue that it may. Countries that protect workers rather than jobs – and thus avoid employment-protection laws – developed stronger venture-capital markets over 1999-2008, especially in highly volatile sectors like computers or energy.

Dahl, Gordon, 16 May 2013, 21096 reads

Remedying a global crisis such as this requires concerted, consensual, coordinated effort. But we’re told economists are divided on what to do next. Is this true? Are we divided? This column praises efforts such as the Economic Experts Panel from the Chicago Booth School of Business. It’s from panels like this – which comprise top economists with differing political views – that we can get a sense of consensus or disagreement on major economic issues.

Aksoy, Hoekman, 15 May 2013, 32843 reads

Increasing agricultural productivity and expanding the agribusiness industry in sub-Saharan Africa is critical for poverty reduction, food security and economic growth. Numerous recent national, regional and G20-level programmes have been initiated to that effect. This column discusses new research showing that political economy forces have a major bearing on the success or failure of agricultural reform programmes. To be successful, policymakers must bear in mind the extent to which existing elites are affected by the redistribution associated with increasing returns for rural producers.

Galasso, Schankerman, 14 May 2013, 20698 reads

Do patents encourage innovation? This column presents a new analysis, suggesting that patent rights block cumulative innovation only in very specific environments. To encourage innovation, remedial government policies should be targeted; a ‘broad based’ scaling back of patent rights is unlikely to be appropriate. Policies and institutions should facilitate more efficient licensing, promoting cumulative innovation without diluting the innovation incentives that patents provide.

Menon, 14 May 2013, 14895 reads

Are free trade agreements good for ‘Factory Asia’? This column argues that rather than supporting ‘Factory Asia’, it is more likely that fragmentation trade has prospered despite the noodle bowl of overlapping FTAs in the region. Inter-regional FTAs, on the other hand, may have been able to indirectly support the growth of production networks among existing members, if they led to increased demand for the final goods that the networks produce.

Manova, Yu, 13 May 2013, 17767 reads

What can we learn from China’s experience as a linchpin in the global value chain? This column presents new research showing that financial frictions influence the organisation of production across firm and country boundaries. If you’re credit-constrained, you might be stuck in the low value-added stage of the supply chain. Strengthening capital markets might thus be an important prerequisite for moving into higher value-added, more profitable activity. China’s experience tells us that liquidity-constrained manufacturers might therefore benefit more from import liberalisation and from the fragmentation of production across borders.

Jansen, de Haan, 13 May 2013, 17382 reads

The European Central Bank has often been criticised for inconsistencies in its policy communications. At the same time, several papers show how ECB communication has been effective. This column resolves this paradox by providing evidence showing that ECB introductory statements were, in fact, quite consistent over the first decade of its operations.

Feyen, Gonzalez del Mazo, 12 May 2013, 24060 reads

Before the global financial crisis, European banks had rapidly expanded their foreign-lending activities. However, this column argues that financial stress in Europe has put this process into reverse and negatively affected credit conditions in developed and emerging markets alike. As European banks repair their balance sheets and rethink their business models in a context of stricter regulatory requirements, financial fragmentation, and a deteriorating European economy, they continue to retrench to home markets.

Crafts, 12 May 2013, 67273 reads

The UK escaped a liquidity trap in the 1930s and enjoyed a strong economic recovery. This column argues that what drove this recovery was ‘unconventional’ monetary policy implemented not by the Bank of England but by the Treasury. Thus, Neville Chamberlain was an early proponent of ‘Abenomics’. This raises the question: is inflation targeting by an independent central bank appropriate at a time of very low nominal-interest rates?

Wood, 11 May 2013, 16864 reads

The world economy seems to be acting in unexpected ways. This column argues that austerity and quantitative easing do not seem to be working out as advertised. There is an urgent need to review the effectiveness of alternative macroeconomic policy approaches, and prepare an internationally agreed pro-growth plan to reflate distressed economies. The outlines of one such plan are presented.

Todo, 11 May 2013, 24286 reads

Japan looks set to participate in the Trans-Pacific Partnership (TPP) negotiations. Reflecting the current debate in Japan, this column assesses what effect the Partnership will have on Japan’s growth. Evidence suggests that the economic effects may be far bigger than the current consensus suggests.

Égert, 10 May 2013, 22717 reads

France has recorded one of the lowest real per capita income growth levels in the OECD over the last 20 years or so. One of the many structural weaknesses causing this weak performance is the French tax system. This column argues that complexity, instability and non-neutrality coupled with very high effective tax rates in many areas of the French tax system put a heavy burden on the economy.

Chwieroth, Walter, 10 May 2013, 23429 reads

The economic consequences of financial crises have been systematically explored. Their political consequences haven’t. This column argues that without paying attention to politics, crises will remain poorly understood. After all, politics shapes policy choices, market sentiment and, ultimately, economic outcomes. Evidence from the effects of banking crises over the past century show that crises have a dramatic impact on the survival prospects of governments.

Stiglitz, 09 May 2013, 40826 reads

The world has seen a hundred financial crises in the past three decades. In this column, Nobelist Joe Stiglitz argues that we could have done much more to prevent this crisis and to mitigate its effects. Looking ahead, we can do much more to prevent the next one. This is a chance to revolutionise flawed economic models, and perhaps exit from an interminable cycle of crises.

Romer, 09 May 2013, 24243 reads

Pre-2008 macroeconomic thinking largely ignored the financial sector as a source of shocks. This column argues that such shocks are not rare, so we need a fundamental rethink of the financial system and macroeconomic policy frameworks. We must think about strong measures that would minimise the chances of anything similar happening again. The reforms considered to date are too small and too meek.

Blanchard, 09 May 2013, 31615 reads

Macroeconomics was challenged by the Global Crisis. In this column, one of the world’s leading macroeconomists provides his take on the highlights of the IMF’s recent conference. He concludes by noting that the conference set a clear research agenda for the future.

Akerlof, 09 May 2013, 43422 reads

Economists did very badly in predicting the crisis. But in this column, Nobelist George Akerlof argues that the economic policies post-crisis have been close to what a sensible ‘economist-doctor’ would have ordered. The lesson for the future is that good economics and common sense have worked well. We have had trial and success. We must keep this in mind with policy going forward.

Colman, Dave, 08 May 2013, 18242 reads

Time and again, research correctly finds that people in developed countries don’t exercise enough. But what information are policy efforts to promote physical exercise based on? This column presents new – and more sophisticated – research that disentangles recreational exercise and cumulative exercise – such as physical activity in (or on the way to) the workplace. An individual’s total physical activity, and not just their recreational exercise, is the salient input into health production because exercise is typically a very small portion of an individual’s total daily physical activity. The sole focus on recreational exercise may well be misleading.

Eijffinger, Mahieu, Raes, 07 May 2013, 15908 reads

Debate about who should be on central-bank committees has resurfaced in recent years. Is it better to appoint experienced central bankers, financiers, NGO workers or civil servants? This column argues that variations in voting patterns change with career background. Evidence suggests that if central banks want a wide range of policy preferences, then getting more academics on committees might be a reasonable strategy for better policy

Auer, 07 May 2013, 34949 reads

Recent data show that the current-account deficits of Greece, Italy, Spain, and Portugal have improved at a rapid pace and are actually close to being balanced. This column reviews recent research that shows this adjustment has been remarkably fast. Compared to mid-2008, these four nations have switched expenditures at a rate that is much higher than the typical rate observed during large rebalancing episodes. A key requirement for a return to a post-crisis Eurozone is thus on its way to being met.

Didier, Schmukler, 06 May 2013, 21286 reads

The growth of China and India’s financial sectors is hard to ignore. This column presents a new dataset on domestic and international capital raising activity and performance of the publicly listed firms in China and India. The data suggest that expanding capital markets might tend to directly benefit the largest firms – those able to reach some minimum threshold size for issuance. More widespread direct and indirect effects are more difficult to elucidate.

Gabriel, Kahn, Vaughn, 05 May 2013, 17649 reads

A relatively unforeseen implosion in housing markets figured prominently in the 2007 meltdown in capital markets and the subsequent downturn in the global economy. This column presents new research on the political geography of subprime lending. Congressional leaders – as well as other recipients of campaign contributions – may have benefited from gains to trade in the direction, pricing, and sizing of subprime mortgage loans.

Balineau, de Melo, 05 May 2013, 11642 reads

The first order of business for the next Director-General of the WTO will be to help broker a deal at the Ministerial Meeting in Bali next December. Following the announcement of reductions in tariffs on environmental goods announced by APEC members last September, there is some hope that a deal might be in hand for a reduction in trade barriers on environmental goods and services. This column reviews the stalemate so far and argues that with little to put on the table, progress at the multilateral level is unlikely.

Mattoo, Subramanian, 04 May 2013, 14719 reads

Global climate cooperation has collapsed but the need for action has not disappeared. This column argues that only radical technological progress can reconcile climate-change goals with development. It argues that four changes in WTO trade rules could facilitate climate-change action and technological advances without unduly damaging trade.

Becker, Ivashina, 03 May 2013, 16915 reads

Fixed-income investors that have targets based on imperfect risk measures are tempted to take on additional risk to raise their portfolio yields. This column argues that when yields are low such ‘reaching for yield’ may be especially attractive. New research that quantifies reaching-for-yield for corporate-bond investors shows that insurance companies, which are regulated based on broad ratings categories, assume additional risk by selectively overweighting risker bonds within categories. There is evidence that this distorts pricing and issuance.

Cherif, Hasanov, 03 May 2013, 23861 reads

Europe’s austerity-first approach has triggered research-based efforts to evaluate the effectiveness of debt-reduction strategies. This column, based on a US empirical study, suggests that an ‘austerity shock’ in a weak economy may be self-defeating. Public-debt reduction historically occurs gradually amid improved growth. If policymakers, firms and households respond as in the past, we should expect lower deficits amid higher growth and, eventually, decreasing debt ratios.

Blanchard, Leigh, 03 May 2013, 68612 reads

The debate about fiscal consolidation reduces too often to shouting matches about the value of fiscal multipliers, or about the existence of a critical debt-to-GDP ratio. This does not do justice to what is a complex choice, depending on many factors. Our purpose in this article is to review the relevant factors at play and allow for a richer discussion.

Büge, Egeland, Kowalski, Sztajerowska, 02 May 2013, 79134 reads

State-owned enterprises have become global players and the subject of much policymaking concern. There is a widespread perception that they may be acting differently when competing with private firms in the global market place. This column introduces a new database on state-owned firms that shows that more than one in ten of the world’s largest firms are state-owned. These new data should help governments formulate informed and balanced policy responses.

Aizenman, Pasricha, 02 May 2013, 15299 reads

Recent years have seen a return to the capital controls policy debate. Presenting new data, this column argues that liberalisation of capital-outflow controls can allow emerging-market economies to reduce net capital inflow pressures, but may cost emerging economies the fiscal revenues that external financial repression generates.

Merola, Pérez, 01 May 2013, 16340 reads

Who should we trust when it comes to fiscal forecasts: governments or independent agencies? This column argues that this question is, in fact, a red herring: empirical evidence suggests that in the past, international agencies’ fiscal forecasts were partially affected by the same problems that the literature widely acknowledges for governmental forecasts. An attractive solution is independent national forecasters.
