Recent years have seen emerging market economy inflation rates converge towards developed economy rates, as well as convergence between emerging markets. The sustained improved inflation performance in emerging markets has occurred even as unemployment in many of these economies has fallen to record lows. This column attributes the improved performance to two factors: increases in monetary policy credibility following the widespread introduction of inflation targeting, and a reduction in the frequency of emerging market currency crises, reflecting a secular improvement in their balance sheets.

Innovation is widely seen as central to the growth of developing countries, and available evidence suggests that the returns to R&D investment should be extremely high.  Yet low-income countries invest very little. This column suggests that this is due to the increasing scarcity of a wide array of factors complementary to innovation, and that this explains the lack of convergence of low-income countries to the technological frontier.

Since Italy’s monetary unification some 155 years ago, income per capita in the South (the Mezzogiorno) has fallen from virtually the same level as in the Centre-North to little more than 55% of the Centre-North’s level. This column asks why East Germany hasn’t suffered the same fate since German monetary unification 25 years ago.  East Germany is not like the Mezzogiorno because of labour market flexibility, different evolutions of the tradeable sector, and the weight of history.

Previous research has shown that the corporate governance practices of firms are constrained by the legal standards of their country of incorporation. This column explores how an active international market for corporate control can substitute for weak institutions in a host country. Using firm-level data from 22 countries, it shows how cross-border M&A activity improves the governance of non-target firms in the same industry, via peer pressure. These findings provide evidence for corporate governance improvements as a novel positive spillover from FDI.

The focus of European policymaking in the 1990s was on meeting a set of nominal criteria. This chapter argues that instead the focus should be on institutional reform and convergence. The main issues that need to be addressed are related to state capacity (tax collection), property rights protection, investor rights, red tape, and administrative-bureaucratic quality. If Europe is to proceed with an even closer union, it should set up institutional rather than nominal targets.

Today’s Eurozone fiscal discipline is the amalgamation of reforms implemented over ten years, with the latest and largest changes agreed in crisis settings. This column argues that the result fosters neither growth nor stability since actual fiscal policy has been powerfully procyclical. The focus on intermediate targets has distracted attention from the final objectives – debt sustainability and economic convergence. A drastic simplification of the current rules is proposed.

Just like the East Asian Tigers, the Lions of Africa are now growing much faster than the developed economies. However, this column shows that the growth escalators in Africa are different than in East Asia. The East Asian Tigers benefitted from a rapidly expanding manufacturing sector. The African Lions are benefitting from increases in productivity in the service sector, while the agricultural sector remains unproductive.

A key question in economics is whether poor countries will automatically close the income gap with rich countries. However, different empirical methods yield different answers – growth regressions suggest convergence, whereas tests of distribution dynamics suggest divergence. This column discusses recent research that reconciles these two strands of the literature. It extends the benchmark growth regression model to include a parameter that determines the share of new technologies a country can adopt each year. The result is that, although each country converges to a growth path, the growth paths themselves may diverge.

Poor countries have access to world markets and rich countries’ technologies. In principle, they should catch up. Yet the record belies this expectation. But this column argues labour productivity in manufacturing displays a clear tendency towards convergence, unconditional on the countries’ institutions or policies. The policies that matter for growth are thus those that bear on the reallocation of labour from nonconvergence to convergence activities.

If rich and poor countries have access to the same technology, shouldn't their productivity levels eventually converge? This would imply that poor countries should grow more quickly until they catch up – but such a tendency has never been proven. CEPR DP8631 shows that this convergence in output does in fact occur – but within manufacturing sectors rather than in economies as a whole.

The authors of DP6456 focus on the extent to which monetary union has led to the integration of financial markets across the euro area, and in particular investigate the effects of two dimensions: the unification of bond markets, and the anchoring of long-run inflation expectations.
