The growing role of global digital players with innovative business models is shaking up traditional markets. Does the digital economy constitute a fundamental break with the industries of the past? In theory, the economic principles underlying competition policy still stand. But given the acceleration of network effects and the use of vast quantities of personal data, competition authorities must adapt their control tools and improve their digital skills.

G7 countries activated several economic policy levers to respond to the 2008 crisis, in particular monetary and fiscal policy. As a result, their ability to stimulate the economy or deal with future crises has been reduced. Consequently, the temptation to conduct beggar-thy-neighbour policies, despite their harmful effects, could be exacerbated. Even though its weight in global GDP has declined significantly since the late 1980s, the G7—whose presidency is held by France in 2019—remains the appropriate forum for curbing this temptation.

What role does the international environment play in shaping US monetary policy decisions? To measure its influence, we construct an international indicator extracted from minutes of Fed monetary policy committee meetings. In a Taylor rule model, we show that the indicator has a significant and negative impact on the fed funds rate. Discussions centred more on the international environment may thus be associated with greater monetary policy easing.

The contribution of foreign trade to French growth was strongly negative between 2014 and 2016. Although, on average, the contribution from sectoral specialisation is more positive in France than for its European partners, it also implies a dependence on a limited number of sectors. The difficulties experienced by France's stronghold export sectors explain a large part of the downturn in the French trade balance between 2014 and 2016.

No one wins a trade war. Based on a multi-region dynamic general equilibrium model (GIMF), we show that a global and generalised 10 percentage point increase in import tariffs could reduce global GDP by 1% after two years. This effect could be amplified by a fall in productivity, a rise in the financing cost of capital and a decline in investment demand. Taking all these factors into account could result in lowering global real GDP by up to 3% after two years.

Reducing current account imbalances is often equated with curbing excessive exports or imports. However, legacies of the past can develop their own dynamics due to accruing income flows. Indeed, in some countries that have accumulated large foreign liabilities, current account adjustment has been impeded by large negative income flows despite substantial improvements in the trade balance.

The share of imports from low-wage countries in French households’ consumption increased threefold from 1994 to 2014. These less expensive imports lowered inflation in France by 0.17 pp per year on average. This direct effect of imports since 1994 represented a gain of about EUR 1,000 in terms of average household consumption in 2014. However, the indirect effects of opening up to international trade on households’ purchasing power, via wages and employment, were not taken into account.

Google, Apple, Facebook and Amazon are giant companies that reflect the more general phenomenon of concentration which is intensifying in most sectors in the United States. This trend is contributing to an increase in the share of profits and to a decrease in the share of labour in domestic income, as well as to a deepening of inequalities. It is also associated with a decline in the creation rate of new firms and jobs, which could in the longer term weigh on US growth.

The effects of the exchange rate on the exports of European firms depend to a large extent on their productivity. The exports of the most productive firms are less affected by exchange rate variations than those of the less productive firms. At the macroeconomic level, this tends to reduce the effects of the exchange rate on trade.

This blog post summarises a study covering the 1995-2007 period focusing on the local effects of Chinese import competition on the French labour market: the competition displaced jobs in the manufacturing sector; it also placed downward pressure on average hourly wages, and modified the wage distribution, with limited impacts on the lowest wages, probably as a result of the lower limit set by the statutory minimum wage.
