French sovereign spreads have risen in recent months, coinciding with debate over the euro ahead of the country’s presidential elections in May. Italian sovereign spreads have been rising since the beginning of 2016. This column argues that investors are not pricing a break-up of France from the Eurozone. Most likely, they are pricing the possibility that the newly elected French government will not have enough supremacy to undertake important economic reforms. Market perception of redenomination risk in Italy, on the other hand, is rising slowly.

Despite numerous studies exploring how immigration affects local labour markets, there is limited evidence on the impact of immigrants on firms’ productivity levels. Using detailed, firm-level data from France, this column explores how firms react to an increase in the supply of immigrant workers. Provinces with a large increase in immigrant supply experienced higher productivity growth, especially among firms that were initially less productive. This suggests immigration can promote convergence in firm size and productivity levels.

Temporary job contracts account for a substantial proportion of the workforce in countries such as France and Spain, but they can result in high job turnover and instability. This column assesses the impact of government policies that impose taxes on temporary contracts to induce employers to lengthen job durations. Such policies a negative impact on the labour market, reducing the mean duration of jobs and decreasing job creation. The introduction of open-ended contracts with no termination cost for separations occurring at short tenure may be more effective.

Regulation is a barrier to trade. This column uses French firm-level panel data to assess how technical barriers to trade impact firms’ exports. In the presence of stringent barriers, exporters balance the cost of complying with this regulation against the fixed cost of entering a new market. Barriers reduce the number of exporting firms in each sector-destination, especially in sectors with many multi-destination firms.

A recent Vox eBook examined the potential issues facing various EU members when it comes to negotiating with the UK over Brexit. This column, taken from the ebook, suggests that France is likely to seek to include the UK in a comprehensive free trade zone to maintain easy access to the UK markets, but with a view to safeguarding its own competitiveness.

Job polarisation has been documented in many large developed economies over the past two decades. This column shows how the growth of ICT has contributed to these trends. Using French firm-level data, it documents the declining share of middle-wage jobs, and identifies an increase in the share of technology-related jobs as an important contributing factor. Firms with more ‘techies’ are also found to grow faster than less techie-intensive firms.

In light of the Eurozone Crisis, some countries have implemented reforms to collective wage bargaining institutions, which can be responsible for wage rigidities that are problematic in the face of rising unemployment. This column describes collective wage bargaining in France and how national minimum wage increases are transmitted to wage floors set by industry-level agreements. An increase in the national minimum wage leads to an increase in negotiated industry-level wage floors, which firms then use as references for their wage policy. This might partly explain why French base wages have continued to increase despite recent rising unemployment.

The business cycles of countries with greater bilateral trade and multinational production linkages are more closely correlated. But the meaning of this empirical relationship is not well understood. Some contend that these linkages allow for the transmission of shocks across countries, while others argue that countries that trade more with each other are similar in other ways and are thus subject to common shocks. Using data from France, this column examines the properties of international co-movement at the firm level. Even after controlling for common shocks, there is still substantial evidence of transmission of shocks through trade and multinational linkages. Furthermore, trade linkages matter more than multinational ones, especially when it comes to the aggregate impact.

Assimilation of migrants can be measured in various ways, one such measure being their access to the homeownership market. This column argues that the evolution of homeownership rates of immigrants is a complex process, with important selection effects. In France, the homeownership rate among northern African immigrants lags behind not only that of natives, but also southern European immigrants. A possible reason is discrimination against northern African immigrants not only on the labour market, but also on the credit and housing markets.

The recent influx of refugees to Europe has stoked security fears and created anxiety about the social and economic consequences. This column provides new quantitative indicators for the intensity of migration-related fears and policy uncertainty, based on newspaper articles. The indices are presented for the US, UK, France, and Germany, and extend back to 1995. They show that recent levels of concern and uncertainty in European countries about migration are unprecedented.

Industrial classifications tend to depict the economy as a collection of separate sectors, and arbitrary lines are consequently drawn between these sectors. This column argues that this way of thinking ignores the complexity of production processes and management strategies, creating a divide between ‘manufacturing’ and ‘services’ which is stronger than it should be. In fact, manufacturing firms often produce and sell services to third parties – known as ‘servitisation’. Economic policies that fail to take into account the dual aspect of the activities of manufacturing firms may prove inadequate.

As the Eurozone crisis lingers on, euro exit is now being debated in ‘core’ as well as ‘periphery’ countries. This column examines the potential costs of euro exit, using France as an example. The authors estimate that 30% of private marketable debt would be redenominated, but since only 36% of revenues would be redenominated, the aggregate currency mismatch is relatively modest. However, the immediate financial cost of exiting the euro would nevertheless be substantial if public authorities were to bail out systemic and highly exposed companies.

The effect of trade protection of infant industries in developing countries on their long-term growth has been widely debated. This column provides evidence on this topic using a novel dataset from the Napoleonic blockade against British trade. The author analyses the effect of this temporary trade protection on the cotton spinning as an infant industry, employing within-country variation in the trade protection. In the short run, better protected regions increased their production capacity in the infant industry. There is a persistence of this productivity in the long run as well.

The Global Crisis has raised the interest of banks in using quantitative controls, such as credit controls. This column discusses a relatively recent historical episode of credit controls in France. During this episode the role of interest rates was almost eliminated. Quantitative controls effectively decreased output and prices in the short-run. The difficulty for the Central Bank stemmed from the fact that it had to change its instruments constantly. This historical episode demonstrates that macroprudential tools can have substantial effects on monetary policy.

The world is urbanising quickly but many cities are poorly located. Such misplacement is associated with bad access to the world markets and frequent natural disasters. This column explores historical evidence of French and English towns during the Roman Empire and in the Middle Ages. Path-dependency in the city locations explains the difference in their development and suggests relevant policymaking lessons.

While quality upgrading is always viewed positively in both policy and academic circles, little is known about the macro implications for countries of specialising in high-end varieties. This column presents evidence that high-end variety exporters are less sensitive to trade costs. This implies a greater geographic diversification of exports, which compensates for their higher sensitivity to demand shocks and smoothes aggregate volatility. It also increases export growth when business opportunities arise in distant markets.

Decreasing world market share in exports threatens France’s recovery. Traditional determinants of exports do not fully explain the downturn. This paper presents a novel explanation for France’s declining exports: the real-estate boom. Strong profitability in the construction industry, led by rising house prices, diverted capital and labour from export-intensive industries. These results suggest a strong warning against policies supporting property ownership as an end in itself.

The unemployment rate in France is roughly six percentage points higher for African immigrants than for natives. Why? This column argues that the explanation is spatial: recent immigrants tend to have much longer commute times. Research suggests that in the region of 20% of the employment gap between the French minority and the French majority can be put down to commute times, but more research is needed, especially in France where research into the ethnic unemployment gap is scarce.

Every academic has an opinion about what makes a good department. This column brings evidence from French economics departments. It suggests that larger departments are associated with slightly more but no better publications per academic. And while diversity in terms of researcher quality lowers average publication quality, diversity in research topics increases it.

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.
