Ripple Effects from Thailand’s Coup

Thailand just had another coup, its first since 2006 but its twelfth since 1932. Here are a few things statistical analysis tells us about how that coup is likely to reverberate through Thailand’s economy and politics for the next few years.

1. Economic growth will probably suffer a bit more. Thailand’s economy was already struggling in 2014, thanks in part to the political instability to which the military leadership was reacting. Still, a statistical analysis I did a few years ago indicates that the coup itself will probably impose yet more drag on the economy. When we compare annual GDP growth rates from countries that suffered coups to similarly susceptible ones that didn’t, we see an average difference of about 2 percentage points in the year of the coup and another 1 percentage point the year after. (See this FiveThirtyEight post for a nice plot and discussion of those results.) Thailand might find its way to the “good” side of the distribution underlying those averages, but the central tendency suggests an additional knock on the country’s economy.

2. The risk of yet another coup will remain elevated for several years. The “coup trap” is real. Countries that have recently suffered successful or failed coup attempts are more likely to get hit again than ones that haven’t. This increase in risk seems to persist for several years, so Thailand will probably stick toward the top of the global watch list for these events until at least 2019.

3. Thailand’s risk of state-led mass killing has nearly tripled…but remains modest. The risk and occurrence of coups and the character of a country’s national political regime feature prominently in the multimodel ensemble we’re using in our atrocities early-warning project to assess risks of onsets of state-led mass killing. When I recently updated those assessments using data from year-end 2013—coming soon to a blog near you!—Thailand remained toward the bottom of the global distribution: 100th of 162 countries, with a predicted probability of just 0.3%. If I alter the inputs to that ensemble to capture the occurrence of this week’s coup and its effect on Thailand’s regime type, the predicted probability jumps to about 0.8%.

That’s a big change in relative risk, but it’s not enough of a change in absolute risk to push the country into the end of the global distribution where the vast majority of these events occur. In the latest assessments, a risk of 0.8% would have placed Thailand about 50th in the world, still essentially indistinguishable from the many other countries in that long, thin tail. Even with changes in these important risk factors and an ongoing insurgency in its southern provinces, Thailand remains in the vast bloc of countries where state-led mass killing is extremely unlikely, thanks (statistically speaking) to its relative wealth, the strength of its connection to the global economy, and the absence of certain markers of atrocities-prone regimes.

4. Democracy will probably be restored within the next few years… As Henk Goemans and Nikolay Marinov show in a paper published last year in the British Journal of Political Science, since the end of the Cold War, most coups have been followed within a few years by competitive elections. The pattern they observe is even stronger in countries that have at least seven years of democratic experience and have held at least two elections, as Thailand does and has. In a paper forthcoming in Foreign Policy Analysis that uses a different measure of coups, Jonathan Powell and Clayton Thyne see that same broad pattern. After the 2006 coup, it took Thailand a little over a year to get back to a competitive elections for a civilian government under a new constitution. If anything, I would expect this junta to move a little faster, and I would be very surprised if the same junta was still ruling in 2016.

5. …but it could wind up right back here again after that. As implied by nos. 1 and 2 above, however, the resumption of democracy wouldn’t mean that Thailand won’t repeat the cycle again. Both statistical and game-theoretic models indicate that prospects for yet another democratic breakdown will stay relatively high as long as Thai politics remains sharply polarized. My knowledge of Thailand is shallow, but the people I read or follow who know the country much better skew pessimistic on the prospects for this polarization ending soon. From afar, I wonder if it’s ultimately a matter of generational change and suspect that Thailand will finally switch to a stable and less contentious equilibrium when today’s conservative leaders start retiring from their jobs in the military and bureaucracy age out of street politics.

    It didn’t stabilize over the past eighty years (or perhaps the coup system paradoxically became part of the stabilization). If the system becomes stabler with the resignations of conservatives in coming years, does that mean that there’s been a fundamental shift in the basics of Thai politics and politicians haven’t realized that they’re using tools that have a different impact from how they used to?

    Jay. I think there is a time lag. Coup are the final result. Political instability can be either the cause or effect of GDP growth. I checked your data and didn’t see a time shift. Identifying when the process of a coup started in order to build a relationship to GDP is tricky. Secondly, in using GDP quarterly data, hides the leading and lagging economic sectors and signals. Great stuff. Keep it up.

    Interesting but this does not take into account the real motive behind the coup, a motive that may well throw off the statistical analysis: The Royal Succession…

    Full agree. When military announced today that the had the approval of the have royals, GDP to coup link weakens.

      Doesn’t make it impossible for the GDP link to exist, but I recall that the last time this happened the first thing the generals did was go to the king to swear their loyalty. This time they’re stating the king gave his backing. Sure sounds like a leading factor.
