Trade Costs of Border Controls in the Schengen Area

Yves here. This is more important than it might seem. One of the key benefits of the European Union has been the ease of movement of goods and people across borders. The refugee crisis has led to a resumption of border controls by quite a few states.

This matters because, as this column confirms, the former friction-free borders produced economic gains for member states. Now that the EU is suffering stress on lots of fronts, not just refugee policy but also increasingly discordant economic relations, the border restrictions undo one of the key raisons d’etre for the entire exercise.

And I suspect some of the glue is psychological, not just purely economic. For instance, if you are in the South of France, you can pop into Italy for a lunch or a day trip. With tougher border controls (mind you, this is a hypothetical at this point), the hassle and delay would probably cut into this practice severely. That doesn’t just reduce commerce. It also increases the sense of separateness of neighboring countries.

This post does some useful, granular analysis, examining the costs of tightening borders along refugee routes versus that of the end of the Schengen system, as well as who has the most to lose.

Time and again, the Eurobarometer surveys show that a vast majority of Europeans view the free movement of people, goods and services across borders as the most important achievement of the EU. This is probably because the removal of identity checks at internal EU borders through the Schengen Agreement is a very tangible advantage of European integration. However, since autumn 2015, several EU member states have reintroduced border controls in a reaction to the refugee crisis and terrorist attacks.

Schengen has facilitated travel within Europe. However, one motivation for Schengen always has been the promotion of cross-border trade in goods and services (Ademmer et al. 2015). The idea is that the removal of border waiting times reduces trade costs, thereby stimulating cross border exchange and the mobility of service providers and consumers. This should yield higher welfare for EU citizens. The reintroduction of controls puts these gains at risk.

In this contribution, we ask:

  • Has Schengen really promoted trade in goods and services, and if yes, by how much?
  • Which EU member states benefit the most from it?
  • What are the trade and welfare costs of the border controls currently notified to the Commission?
  • And, what if the border controls were reinstated at all internal borders?

To answer these questions, we draw on our recent research (Felbermayr et al 2016). More precisely, we apply an econometric gravity model to historical data (1995-2011) to measure the trade effects of the Schengen Agreement. We then turn to a simple counterfactual analysis based on the most recent data in which we impose border controls on certain intra-EU borders.

Setup

The Schengen Agreement, first enforced in 1995 amongst six countries (BENELUX, France, Germany, Italy), has grown over time and today includes about 400 million citizens in 26 countries (see Figure 1). Not all EU members are part of Schengen, but some non-EU countries are. All EZ countries are Schengen members, but they ratified the agreement at different times. From an econometric point of view, the often bemoaned variable geometry of Europe is an advantage. It allows us to use panel econometrics to disentangle the different effects of the EU, the Eurozone, and Schengen membership and of other trade agreements (e.g. EFTA, EEA, or pre-accession treaties).

The trade effects of the Schengen Agreement have an obvious spatial dimension. A land-borne trade flow between two countries in Europe may cross only one internal border (e.g. France to Germany) or up to eight of them (e.g. Portugal to Finland). Hence, Schengen membership treats country pairs in a heterogeneous way. This feature is ignored in the small existing literature (e.g. Davis and Gift 2013). What is more, Schengen outsiders such as the UK or Turkey can also benefit from the agreement to the extent that their trade flows transit through Schengen space. To deal with this, we combine GIS data with information from Google Maps to count the number of Schengen borders crossed by truck (and ferry) along the shortest road distance between trading country pairs. This count variable is our measure of interest.

Schengen Membership Has Promoted Trade in Goods and Services…

We carried out a gravity regression analysis on data from the World Input-Output Data (WIOD) project (Felbermayr et al. 2016). This allows the separation of services trade from goods trade, and international from intra-national trade flows. The data are available for 40 countries (including 27 EU members) and have been described by Escaith and Timmer (2012). The econometric model follows the recommendations in Head and Mayer (2015). Figure 2 shows that – conditional on membership in the EU, in the Eurozone, or in any other regional trade agreement (and conditional on the usual gravity controls and a host of pair and time fixed effects) – the removal of controls on one internal border is equivalent to a reduction of a tariff by 0.7 percentage points. This effect is precisely estimated for goods, but less so for services. Numerous robustness checks in our paper corroborate this general finding.

EU membership is much more important than Schengen, though. The cumulated effects of the customs union and the single market are equivalent to a tariff reduction of almost 18 percentage points for goods and 7 percentage points for services. Other RTAs and the euro also yield larger trade cost reductions.

Source: Own calculations from a PPML gravity model, using estimates from Felbermayr et al (2016) and applying a trade elasticity of 5. 95% confidence intervals. RTAs are regional trade agreements such as the EU-Switzerland bilaterals, or EFTA.

We find these effects plausible. Evidence from the US-Canadian border or from current external Schengen borders suggest waiting times that average 20 minutes (Ifo 2016). Bottom-up estimates yield much smaller costs, but are less comprehensive by construction. The estimates suggest that the tariff equivalents of 3% assumed in recent policy work (Aussilloux and Le Hir 2016, Böhmer et al. 2016) may be too high.

When a trade route involves several internal borders, the cost savings accumulate – a truck from Italy to Germany crosses two internal borders so that Schengen is equivalent to a trade cost saving of about 1.4%; a truck from Portugal to Poland crosses four internal borders so that Schengen saves about 2.8%. However, more than 80% of intracontinental trade in Europe crosses only one or two internal borders (see Figure 3).

…but Some Countries Benefit More from Schengen than Others

Clearly, different countries will be affected differently by Schengen, simply because geography, history, and specialisation patterns imply that countries are heterogeneous with respect to the average number of internal borders that trade flows cross. In other words, every country has its own breakdown analogous to Figure 3.

Figure 4 shows average cost savings from Schengen for various countries. For example, across all intracontinental trade flows of Austria, Schengen amounts to trade cost savings of 0.81% for goods and 0.75% for services. Thus, the country occupies a middle ground. For countries at the periphery such as Portugal or Finland, Schengen matters more. It is equivalent to trade cost savings for goods of 1.28% and 1.59%, respectively. In contrast, Ireland, whose main trade partners are the Schengen outsiders UK and US, the savings amount to only 0.42%. Figure 4 also shows that Schengen outsiders such as Russia or Turkey benefit from the removal of internal border controls, too.

The Costs of Border Controls Along Refugee Routes: An Approximation

As a reaction to the massive inflow of refugees, in September 2015, Germany introduced border controls at the Austrian border; in November, Sweden started ID checks at the Öresund Bridge; and Austria reinstated controls at its border with Slovenia and Italy. The terrorist attacks in Paris in November 2015 led to border controls at French borders. Considering all border controls reported to the EU under Article 23 et seq. of the Schengen Borders Code since summer 2015, and applying our estimates, we find that overall goods and services trade of EU-28 countries declines, on average, by 1.3% compared to the status quo in 2011; this corresponds to an annual decline in trade volumes of €70.19 billion. Using a trade elasticity of 5 in the welfare formula of Arkolakis et al. (2012), this effect lowers aggregate real GDP of EU28 members by €12.51 billion, or 0.10% of GDP. However, there is a great degree of heterogeneity, as countries differ with respect to the importance of trade with partners in the southeast of Europe (see Figure 5).

The Costs of a Complete Schengen Collapse

What if identity checks were to be reinstated at all internal borders? In this scenario, our calculations suggest that overall goods and services trade of EU28 countries declines, on average, by 4.2%, relative to the status quo in 2011; this corresponds to an annual decline in trade volumes of €221.34 billion compared to a counterfactual situation without any border controls imposed within the Schengen area. The aggregate real GDP of EU28 members would fall by 0.31%; that is, by €39.3 billion.

Again, our analysis suggests that peripheral and/or small countries are much more strongly affected than central and/or large ones. Interestingly, Schengen outsiders such as Turkey and the UK would feel the effect, too.

    The same logic about the cost of border controls applies to North America.

    NAFTA could have been a vehicle to “go Schengen.” But the angloparlantes were afraid of Mexican immigration and drugs.

    Now Mexican immigration has reversed to an outflow, and U.S. states are moving toward legalizing cannabis (meaning domestic production displaces imports).

    But post-2001, national security provided a fresh rationale for keeping North American borders locked down.

    Throughout the 20th century, USians could roam freely throughout North America and the Caribbean with nothing more than a drivers license or a voter registration card.

    But our Kongress Klowns took this freedom away from us. As revealed by a new “law” giving the State Dept. the authority to invalidate the passport of anyone owing more than $50K to the IRS, the intention is (like the former Berlin wall) to pen us in. We’re the Soviets now, comrades. Got freedom?

      I kinda think Congress is doing this on purpose because they know that in a couple decades some Americans are going to try and escape south. Put up the Berlin Wall now, while Americans are still afraid of northward immigration, so the American people cant escape later!

    I think the psychological benefits are very high, especially in the Low Countries. I have a friend who lives in a town about 30 km outside Amsterdam, but when I visited, she treated going to Amsterdam like a holiday, she goes there so rarely – when she and her husband go shopping or for a day out, they go to Brussels – they just find it an easier drive and they prefer the shops and the food. Another Dutch friend, in an eastern town, goes to Dusseldorf or other German cities to shop – its cheaper and there is a better choice. It even applies to England – quite a few years back I took the ferry from Kent to Calais and got talking to some retired folks on the boat – turns out this was their weekly trip to France – the ferry was so cheap it saved them money to grocery shop and lunch in France. It seemed the most natural thing in the world to them to do this, they didn’t even see it as ‘travelling’. This might have changed more recently as security concerns means the ferries are not so easy to take.

    If the 80% of Europe felt that their prosperity was stable and secure, some highly visible cooperatioan projects (egen if it is just building a bridge or joint reaearch project) plus a rhetoric of a common and united Europe would be enough to maintain goodwill among the nations. A schengen is secondary.

    Stopping multinationals from buying companies and exporting the jobs to either Germany or low wage countries would be a good start for the PIIGS. Dismantling the all tax havens, starting with called Lichenstein, Ireland would help stop this behaviour , and divert financial wealth from being accumulated in the 1% to the nations… Also a very goid Europe building project
