Despite Narendra Modi’s successful leadership as chief minister of Gujarat, some question his ability to achieve the same progress at the national level as India’s prime minister. This column analyses Modi’s political background and state- and national-level experience to assess his capacity to navigate India through a politically and economically important time towards its goal of becoming a prosperous economy. It finds that while Modi can lean on his Gujarati experience to some extent, in other aspects he will have to depart from his incremental approach to policymaking in favour of radical changes, particularly in the area of employment maximisation.

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.

Policymakers use forecasting to attempt to assess the impact of major events, such as the recent Brexit vote, on the economy. While forecasting has improved dramatically in recent years, the models can still be greatly improved. This column discusses some of the limitations of forecasting models, and how policymakers can make their predictions more reliable. Key considerations are using more data to generate predictions, and using myriad models to eliminate individual misspecifications.

The service sector accounts for much of the output of many advanced economies, and maximising the sector’s output while also minimising regional disparities is an important policy challenge. This column analyses productivity in service sectors in Japan, focusing on economies of urban density. The higher the employment density of the cities in which service firms are located, the higher their productivity, but firms relocating to such cities negatively impacts regional disparity. Further, considerable differences in productivity improvements among sectors indicate there certain industries should be promoted in large cities, and others in smaller cities with lower employment density.

How the trend towards individualism in societies affects economic welfare is debatable, but it is generally agreed that the role of technological progress in spurring individualism is substantial. Exploring the impact of technological progress in a model of individual utility, this column finds that the direct positive effects of technological progress, in the form of innovation and economic growth, may be offset by the indirect negative effects resulting from greater positional competition at the expense of caring activities.

Governments around the world continue to fund tourism promotion policies, even while current economic literature debates whether tourism in the long run benefits the economy as a whole. This column uses the empirical context of Mexico to analyse the economic implications of international and domestic tourism, and the underlying mechanisms. It finds that tourism provides long-run economic gains to households, both at the local level and in the aggregate.

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.

Negative shocks to bank balance sheets are problematic not just for financial markets, but for employment and economic growth more widely. This column uses evidence on a bank liquidity shock in Italy in 2007-10 to show the impact on firms’ production, investment, and employment. Firms borrowing from banks with a high exposure to the shock experienced a more intense fall both in credit flows and in investment expenditure. While the credit cut has been homogeneous across borrowers, firms with easier access to external finance were able to contain the negative consequences of the drop in credit for investment.

The shifting balance between manufacturing and service industries in developed economies has significant implications for long-term growth and international trade. This column uses Japanese firm-level data to analyse the impact of ‘factoryless goods producers’ on overall productivity. As these producers specialise in tasks in which advanced economies have a comparative advantage, it is anticipated that when combined with falling production costs and trade liberalisation, they will contribute to economic growth.

Firms with greater market power can behave monopolistically, and recent research suggests that declining market competitiveness is driving income inequality. While competition authorities already measure the overall impact of their interventions by using customer savings, these measurements do not account for indirect effects of intervention. This column introduces a DSGE model to model competition policy interventions as a negative mark-up shock. Competition policy has a significant and positive impact on growth and jobs, and impacts richer and poorer households differently. Interventions have important redistributive effects that benefit the poorest in society.

Americans have long debated when the country became the world’s economic leader, when it became so unequal, and how inequality and growth might be linked.  Yet those debates have lacked the quantitative evidence needed to choose between competing views. This column introduces evidence on American incomes per capita and inequality for two centuries before World War I. American history suggests that inequality is not driven by some fundamental law of capitalist development, but rather by episodic shifts in five basic forces: demography, education policy, trade competition, financial regulation policy, and labour-saving technological change.

Free trade often comes hand in hand with economic growth. The opportunity for gain is relatively small, according to quantitative models that rely on standard static mechanisms. This column introduces a model to study the diffusion of ideas across countries as a means of increasing productivity, and a quantitative assessment of the role of trade in the transmission of knowledge. How much the transmission of knowledge will impact productivity depends on the openness of the trading countries, current stock of knowledge, and a diffusion parameter.

The US government’s ‘bailout of bankers’ in 2008-09 remains a highly controversial moment in economic policy. Many critics suggest that intervention to relieve household debt may have been more effective in stimulating economic recovery. This column suggests that without federal intervention to stabilise financial markets and recapitalise some non-bank lenders, the magnitude of the economic collapse might have been much worse. While household debt was incredibly important in reducing demand, the financial sector dislocations and the lack of credit also played a critical role.

There is a high degree of correlation between the business cycles of different countries. This is particularly the case in the Eurozone, but also among industrialised countries outside of the Eurozone. Using a two-country behavioural macroeconomic model, this column shows that the main channel for the synchronisation of business cycles is the propagation of ‘animal spirits’ – waves of optimism and pessimism that become correlated internationally.

Theory and empirical data contest the direction of causality in the relationship between economic performance and income inequality – a relationship that is of great political importance. This column uses evidence from OECD countries to show that the relationship is not linear. While some countries can improve economic performance only at the cost of increasing economic inequality, other countries can improve both economic performance and equality without such a trade-off.

By creating liquidity, banks improve the allocation of capital and accelerate economic growth. This column uses evidence from US banks between 1984 and 2006 to evaluate the impact of competition amongst banks on their liquidity creation. It finds that an intensification of competition in the banking industry materially reduces liquidity creation. Furthermore, the evidence suggests that more profitable banks experience a smaller reduction in liquidity creation because of their ability to better absorb risk. Similarly, an intensification of competition reduces liquidity creation more among small banks, who are more engaged in relationship lending.

The first century of modern Greek monetary history has striking parallels to the country’s current crisis, from repeated cycles of entry and exit from the dominant fixed exchange rate system, to government debt built-up and default, to financial supervision by West European countries. This column compares these two episodes in Greece’s monetary history and concludes that lasting monetary union membership can only be achieved if both monetary and fiscal policies are effectively delegated abroad. Understandable public resentment against ‘foreign intrusion’ might need to be weighed against their potential to secure the long-term political and economic objective of exchange rate stabilisation.

Most economists view trade as benefiting countries overall but leading to winners and losers within nations. This column summarises a recent survey about winners and losers from globalisation prepared in the context of the FP7 COEURE project. It stresses that the policy debate should focus on identifying and compensating the losers from globalisation rather than on considering protectionist measures that are detrimental to growth.

Since the Eurozone Crisis a host of monetary and fiscal instruments have been used to try to reinvigorate growth and achieve financial stability, with mixed results. Basel III’s counter-cyclical capital buffer (CCB) is one such instrument which was met with scepticism. This column uses evidence from the Swiss economy to show that given the right circumstances and political will, the CCB can achieve financial stability.

Okun’s law describes the positive empirical relationship between unemployment and the output gap. This column explores how this relationship differs depending on age and gender, taking into account different labour market institutions. Using data for 20 OECD countries over three decades, the authors find that the effect of Okun’s relationship decreases with age. Labour market institutions have similar effects on the unemployment rates of all groups, though magnitudes vary by age and gender.
