The Power of Economists in Government

My excellent colleague Johan Christensen has a new book out with Stanford on the power of economists in government. I talk to him about it here for the podcast we made for my research methods class with Natascha van der Zwan. New episodes will be up soon.

The Trump Russian leak twitter battleground

Gephi has a tool to import tweets and map them as a network through hashtags. This is how it looks with the search key “Trump” just after the news came out in the Washington Post that Trump had allegedly leaked classified information to the Russian Ambassador and Foreign Minister. One can clearly see where the action is (in the orange area), but there seems to be a pro-Trump galaxy around the “MAGA” hashtag.

The network below shows the country participants in yesterday’s Eurovision song contest connected to their top 3 recipients of votes (both jury and call-in votes). The colour of the arrows corresponds to the recipient. We can see the two main contenders Portugal and Bulgaria clearly standing out.

The social base of Marine Le Pen and Emmanuel Macron

Emmanuel Macron and Marine Le Pen will be competing in the election run-off of the French presidential election on May 7th. It is fair to say that Macron and Le Pen propose completely opposed views of what France should be. Macron is a liberal cosmopolitan, is pro-EU and wants to relax employment protection, and Le Pen is a nationalist who champions a stronger role for the state. In recent work we have done with Line Rennwald, we found that the Front National had been the European Party that had moved the furthest to the left when it came to welfare state issues, at least when it came to its agenda (what they actually do is a different story).

In line with this, the social classes that they appeal to are also completely opposed: Le Pen does the best among blue collar workers, while Macron is the most popular among managers and what sociologist call “socio-cultural professionals”, people in the creative industries, doctors, lawyers, intellectuals, and upper social categories (definitions for French categories are here). In 2002, Jacques Chirac had claimed that he represented “La France d’en bas” (France from the bottom) and not “La France d’en haut” (France from above). If we look at socio-economic categories, Macron is the candidate of the “France d’en haut”, and Le Pen the candidate of the “France d’en bas”.

Le Pen and Macron vote shares across socio-economic categories. Data: IPSOS

Using electoral results data from the 1st round combined with socio-economic data on electoral districts (n= 551)  gathered by the French National Statistics Office, we can get an idea of how the Le Pen and Macron votes related to the social composition of districts, and notably the share of manual workers and socio-cultural professionals. I have run a few simple regressions to look at this. An obvious problem in this kind of analysis is that one risks making ecological fallacies: with socio-economic data at the district level, we don’t actually know who votes for Le Pen or Macron. But it can still give some useful information.

We know from opinion polls (e.g data above) that Marine Le Pen scores highest among manual workers. This is in line with recent research in other European countries. Indeed, the share of manual workers in electoral districts is clearly positively correlated with the strength of the Le Pen vote. Not controlling for anything else, a 1 prcentage point increase in the share of manual workers in French constituencies is associated with a 1.45 percentage point increase in the Le Pen vote share. The share of manual workers explains 37% of the variation in the Le Pen vote share, and the relationship is statistically significant at the 99.9% level. This relationship is the opposite for the Macron vote. The greater the proportion of manual workers in a district, the lower the vote share of Emmanuel Macron. For a 1 percentage point increase in the share of manual workers, on average the Macron vote share decreases by 0.85 percentage points (R2=0.34). This relationship is not statistically significant for the Macron vote if we control for the share of managers and immigration, however (click graphs to enlarge).

If we look at the social category of managers and socio-cultural professionals (the core base of the Macron electorate), or what we call “les cadres” in French, this relationship is reversed. The greater the proportion of cadres in an electoral district, the greater the Macron vote share, and the lower the Le Pen vote share.

Another way to look at this not to look at vote shares, and look at how the social composition of districts affects the probability of one candidate winning over the other. For this, I have created a dummy variable that captures who between Le Pen and Macron wins in electoral districts. The graphs below show how this probability evolves at different shares of working class voters in an electoral district. Logically, the probability to win increases with the share of working class voters for Le Pen, and decreases for Macron.

Finally, we can also look at the relationship between economic indicators such as unemployment and the vote shares of the two candidates. I couldn’t find data at the district level, so we can use the level of the department (France’s main administrative division). There is a positive relationship between unemployment and the vote share of Marine Le Pen (R= 0.58), and a negative one for Macron (-0.59) (N=102).

In the table below, I have regressed Le Pen and Macron vote shares by the socio-economic variables mentioned above, controlling for the share of foreign citizens per district. Data from INSEE only include people who do not have French citizenship and not French citizens of foreign descent. Not controlling for anything else, the effect of the share of immigrants is pretty small, (r-square 0.05 for Macron and 0.17 for Le Pen; not shown), but its coefficients are negative for both in the overall model, meaning that greater shares of foreign citizens mean lower vote shares for both candidates.

Will Marine Le Pen be able to draw voters of other candidates?

sankeymatic_1200x1200.png

A question many people ask themselves is whether Marine Le Pen will be able to draw voters beyond her own electorate if she makes it to the second round of the French Presidential election (which looks quite likely). In all scenarios put forward in polls, she loses against all other possible candidates. It is interesting to see how things played out in 2002, when her father made it to the second round against Jacques Chirac.

The graph above shows the transfer of votes between the first and the second round of the French presidential election in 2002. To draw this graph, I have taken the total number of votes for each candidate in the first round, and multiplied it by the proportions given in this exit poll by Ipsos. I have used the Sankeymatic to make the graph. The calculated total for Le Pen and Chirac is a bit different from the final outcome, but as a whole it is pretty accurate.

The obvious problem for Le Pen father was that he wasn’t able to draw any significant transfer of votes. He only increased his vote share by less than a million, mainly thanks to Bruno Mégret (another far right candidate estranged from the Front National) and abstentionnists. Chirac, in contrast, drew not only on the totality of his own voters and the near totality of voters of other candidates, but also drew many people who had abstained in the first round.

Things will probably be different this time. Les Républicains under Sarkozy moved significantly to the right on immigration, making Le Pen’s ideas more acceptable. If Fillon doesn’t make it to the second round, we can expect a non-negligible share of his voters to move to Le Pen. Generally, Marine is surely not as radioactive as her father in the electorate as a whole. We can probably see this in the polls. They were considerably off in 2002, as many respondents were probably ashamed of saying they’d vote Le Pen. This shame is surely less present now.
