The population sizes of cities are highly indicative of their industrial structure. This column identifies the cities in Japan in which manufacturing industries have significant agglomeration, and reveals that the number of these agglomeration cities differs widely across industries, with industries that are located in a smaller number of cities being found in larger cities. There is also considerable churning of population and industrial activities among Japanese cities, with population growth reflecting the development of highway and high-speed railway networks.

Since 2007, there have been large changes in the Swiss franc. This column shows that exchange-rate appreciations do not affect the exports, profits, or stock returns of Swiss companies making sophisticated products. In contrast, rises in the franc decrease the exports, profits and stock returns of firms producing medium-high-technology goods. An economy’s production structure is important for weathering exchange-rate fluctuations.

There is growing interest in measuring the scientific aspects of industrial innovation and performance to understand the economic impact of publicly funded R&D. This column presents new indicators for science-industry linkages in Japan based on a novel dataset combining academic research paper data, patent data, and economic census data. It finds that the academic sector is getting more involved in patenting activities, and that scientific knowledge generated in the sector is being utilised not only in science-based industries, but also in many others.

Economists are just starting to understand how observed input-output linkages and productivity differences are connected. This column investigates how differences in the distribution of sectoral input-output multipliers interact with sectoral productivities to determine cross-country differences in aggregate income. It finds that the impact of the linkages on productivity are substantial, which in turn has significant implications for policy.

Many corporate acquirers impose losses on their shareholders. Conflicted or overconfident CEOs and boards embark on acquisitions that are not in the best interest of the owners of the firm. The governance tool of shareholder voting can represent a potential solution. This column shows that in the UK, where bids for relatively large targets require mandatory shareholder approval, shareholders gain when the transaction is conditional on a vote and lose when it is not. The evidence suggests that the vote puts a constraint on the amount the CEO can offer for the target.

In many countries, electricity supply is cited as a primary impediment to firm growth and productivity. This column assesses the effect of endemic electricity shortages on Indian manufacturers. The average reported level of shortages reduces annual plant revenues and producer surplus of the average plant by 5-10%. While the complete elimination of shortages may not be plausible in the near term, simulations show that interruptible retail electricity contracts could substantially reduce the impact of shortages on manufacturers.

China’s spectacular growth over the 2000s has slowed since 2013. The driving force behind the country’s growth was investment, so the key to understanding the slowdown lies in understanding what sustained investment in the past. This column shows how a preferential credit policy promoting heavy industrialisation explains the trends and cycles in China’s macroeconomy over the past two decades. This policy was not without negative consequences, particularly in terms of the distortions it introduced for business finance. Going forward, China needs to focus on creating the right incentives for banks to make loans to small productive businesses.

Iceland’s banking system is ruined. GDP is down 65% in euro terms. Many companies face bankruptcy; others think of moving abroad. A third of the population is considering emigration. The British and Dutch governments demand compensation, amounting to over 100% of Icelandic GDP, for their citizens who held high-interest deposits in local branches of Icelandic banks. Europe’s leaders urgently need to take step to prevent similar things from happening to small nations with big banking sectors.
