La diffusion spatiale des pièces euro étrangères en Belgique et en France

With the 2002 introduction of the euro as a common currency in Europe, the possibility has emerged to assess international mobility using this new tracer, given that every coin bears a specific national side. Using a simple two-country framework, four dynamic modeling strategies were designed in order to simulate the diffusion of coins and to understand how this diffusion is affected by population size, mobility rates and coin exchange processes. Methodological implications are raised with respect to aggregation, synchronicity and stochasticity issues. Although each model converges to an equilibrium, the time to reach this end stage and the level of coin mixing in each country strongly varies with the modeling strategy. Calibration is undertaken with French data, using mobility rates as adjustment variables. The experiment shows that convergence to a perfect mix of coins can only be obtained if reciprocal exchanges are modeled, with a time horizon around 2064-while non-reciprocal models indicate an imperfect mix converging in the year 2020 at the latest.

“…those explaining why there is a higher probability to find German coins rather than Luxembourg coins in France (size effect) or why we have a higher probability to find Belgium rather than Portuguese coins in the Netherlands (distance effect). Adding to the socio-economic effects, Berroir, Grasland, Guérin-Pace, and Hamez (2005) showed barrier effects of languages by comparing the diffusion of French coins in the French-speaking and Flemish-speaking regions of Belgium.…”

International audienceWe examine how geographical structures impact diffusion processes within a regional system. From the example of euro coin diffusion across countries, we show how the relative position and population endowment of regions impact our understanding of interregional mobility, beyond simple spatial interaction effects. The mix of coins of different origins is a complex but unique trace of the movement of individuals within a common currency area, potentially revealing a new facet of European integration. We simulate an individual-based dynamic model where agents move and exchange coins across regions. We analyse the convergence towards a homogeneous mix of coins through time for a series of different theoretical spatial systems. This sensitivity analysis demonstrates the impact of the regularity and aggregation levels, or centrality/periphery effects, on spatial diffusion dynamics. We then calibrate the model against empirical data for the regions of 5 European countries and provide estimates of mobility rates, distance decay and population attractiveness factors, affecting the diffusion of coins, hence international movements and European integration

“…Several factors explaining variations in the presence of foreign coins on French territory were highlighted initially (Grasland and Guérin-Pace, 2004). Mechanical effects (the number and value of the coins in a purse) were distinguished from temporal effects (the period of time since the euro was brought into circulation) and the commonplace effects of spatial interaction such as proximity to the border of a euro-zone country or the population size of neighbouring countries (Berroir et al, 2005). The impacts of the individual characteristics of the coin carriers-age, profession, socio-professional category, place of residence-on the presence of foreign coins are more difficult to identify, as low-mobility individuals can come into contact with numerous foreign coins simply by living near an airport.…”

This study examines the social and territorial structure of the relations between Eurozone countries and residents that we grasp by studying the diffusion of foreign euro coins (2002-2011). As a euro coin is conveyed across space by persons, it offers a good representation of both social and spatial networks, as well as it allows the study of both social and territorial inequalities with regards to international connectiveness. We use a series of individual-level representative surveys describing the content of the money bag of an amount of 21,669 respondents and analyse internationalization differences using logistic regressions. The results show that students and executives are the social categories that are the most connected to neighbouring peoples and which are therefore potential vectors of a European identity. They also demonstrate strong spatial and territorial variations of the openness of places and people to the rest of Europe-everything else being equal.
