Multiplicity (not starring Michael Keaton)

Duck of Minerva did a public service by hosting a debate between Matt Kroenig, Todd Sechser and Matthew Fuhrmann (see herehere, and here). The topic was nuclear superiority and crisis bargaining. Those are abstract words, but they are relevant for how we think about the United States’ ability to compel, say, North Korea in a crisis. But I think the debate should be of interest to anyone interested in applied methods in IR.

For me, Sechser and Fuhrmann’s arguments are the more compelling. In particular, they critique how Kroenig squeezes the appearance of more data out of a very small number of events:

Kroenig confronts a basic challenge in his empirical analysis: nuclear crises are rare.  Specifically, he has only 20 nuclear crises in his dataset (drawn from the ICB dataset). Yet he winds up with 52 observations, enough to generate a statistically significant correlation.  How does he obtain such a large dataset from such a small set of crises? The answer is that Kroenig simply duplicates each observation in the dataset, so as to double its size. A single observation for the Cuban Missile Crisis, for example, now becomes two independent events in his dataset: a victory for the United States, and a defeat for the Soviet Union.  This is inappropriate: the two observations are measuring the same event. Kroenig is not actually observing more data here; he is simply reporting the same event twice.  This is equivalent to an exit poll that lists each respondent twice in the sample – once voting for candidate X, and once voting against candidate Y – and then claims to have twice the sample size.

As quantitative methods have pushed into new areas, including areas with very few observations, their employers have suggested greater confidence than is deserved about their findings. In fact, at some point, my guess is the whole enterprise of treating dyad-years as meaningfully independent observations will come collapsing around our heads. It’s been a while since I looked at it, but Erickson, Pinto and Rader have a paper that concludes “typical statistical tests for significance are severely overconfident in dyadic data.”

Political science’s great challenge is knowing what we know. Quantitative methods are not a panacea for this problem.

Re-Reading Juan Linz at the Fiscal Cliff, Contd.

I just saw that another person–in addition to Matt Yglesias and me–thinks Juan Linz’s old writing on the crisis-prone nature of presidential systems is increasingly applicable to the United States, despite the United States being a notable outlier in the original analysis. His name is Juan Linz.

Representation by law? Gender quotas in Brazil’s elections

On January 1st, 2013, 7,646 women took office as members of the local legislatures in more than five thousand municipalities in Brazil. 665 women were also elected as mayors in these municipalities, marking the largest number of women to enter local office in Brazil’s history.

Is this latest achievement part of the trend started two years ago, when on January 1st, 2011, Dilma Rousseff took office as President of the country? After all, in 2010, not only did Brazil elect its first female president, Marina Silva also gained the largest vote share of any third-runner for the presidency since re-democratization in 1989. Or, are these numbers the direct effect of the gender quota law enacted in 2009? This law requires that a minimum of 30%, of women be on party lists for proportional elections (local, state, and federal legislators). This 2009 law, applied for the first time in the 2012 elections, made a similar 1997 gender quota law more effective by forcing parties to actually enlist women to their tickets.

Examining only the absolute number of elected women in Brazil can be misleading, however. Indeed, careful examination suggests that the proportion of elected women has only risen slightly despite the more effective enforcement of the quota law.

local

The graphs above tell us part of the story. We can see that the proportion of elected women still remains significantly less than elected men. The first graph indicates that  even though the number of female candidates for local chambers has risen sharply (due to the enforcement of the quota law), the proportion of elected local female legislators is still very small.  Similarly, the proportion of elected state and federal deputies is remarkably stable even through there has been a rise in the number of candidates in the 2010 elections, as shown in the second graph. Given that the gender quota does not affect majoritarian elections, it is a bit surprising that the proportion of elected female mayors has been rising more rapidly than the proportion of elected female local legislators.

One possible explanation for the under-performance of women in elections for local chambers is the lack of resources and support provided by the parties, which recruit women simply in order to formally reach the threshold demanded by the law. This is a difficult hypothesis to test but the graphs above shed some light on it. For instance, the number of female candidates who identified as “housewives” increased in the 2012 elections. This may reflect the greater influence the Electoral Justice had on parties to obey the gender quota law, leading parties to enroll female candidates who were related to existing male candidates.

The gender quota law provides a necessary first step towards equal gender representation. Nevertheless, making sure women have spots on party lists does not guarantee that they will have the resources or access to other factors necessary to get elected.  Like other types of affirmative action, quotas tackle issues of inequality by guaranteeing access of underprivileged groups to the arenas in which they are systematically under-represented (these arenas could be the realm of elections, universities or jobs, among others). Yet, whether this type of affirmative action proves ultimately effective hinges upon empirical and normative assessments.

Re-reading Juan Linz at the Fiscal Cliff

Though it seems likely that Vice President Biden, Mitch McConnell, and John Boehner have found an agreement that can pass both the Senate and the House, it seems equally likely that any such agreement will be merely a stop gap measure. There will be some future cliff that the politicians construct for themselves to force new and exciting brinksmanship down the line. (Andy Borowitz tweeted on December 31, “Assholes Race Against Clock to Avoid Crisis They Created.”)

As we await the results of this latest episode in dysfunction, it is worth underlining that this crisis is likely NOT a result of bargaining ineptitude or petulance. Rather, the system of checks and balances built into the U.S. constitution is crisis-prone. Let’s revisit Juan Linz’s famous 1990 essay on the topic, which is worth quoting in length:

[W]hat is most striking is that in a presidential system, the legislators, especially when they represent cohesive, disciplined parties that offer clear ideological and political alternatives, can also claim democratic legitimacy. This claim is thrown into high relief when a majority of the legislature represents a political option opposed to the one the president represents. Under such circumstances, who has the stronger claim to speak on behalf of the people: the president or the legislative majority that opposes his policies? Since both derive their power from the votes of the people in a free competition among well-defined alternatives, a conflict is always possible and at times may erupt dramatically. There is no democratic principle on the basis of which it can be resolved, and the mechanisms the constitution might provide are likely to prove too complicated and aridly legalistic to be of much force in the eyes of the electorate. It is therefore no accident that in some such situations in the past, the armed forces were often tempted to intervene as a mediating power. One might argue that the United States has successfully rendered such conflicts “normal” and thus defused them. To explain how American political institutions and practices have achieved this result would exceed the scope of this essay, but it is worth noting that the uniquely diffuse character of American political parties—which, ironically, exasperates many American political scientists and leads them to call for responsible, ideologically disciplined parties—has something to do with it. Unfortunately, the American case seems to be an exception; the development of modem political parties, particularly in socially and ideologically polarized countries, generally exacerbates, rather than moderates, conflicts between the legislative and the executive.

Three things are worth emphasizing.

First, I don’t see the armed forces inserting themselves, but that does not remove the possibility of a constitutional crisis (here, the ultimate authority will reside in the Supreme Court rather than the Pentagon).

Second, Linz in 1990 did not anticipate that the ideological polarization in American political parties would grow much worse almost immediately after he wrote his words. I leave the causes of this polarization over to my more than capable Americanist friends, who get paid to assess such things. My personal pet theory is that corruption helped overcome polarization in the 19th century and the fight for and against civil rights messed up clear party lines in the South in the 20th century, which messed up clear party lines everywhere. And if you were to find an inflection point in ideological polarization (where polarization started to get worse), the 1960s seem like a good place to locate it using the old eyeball technique. See this graph from a Keith Poole paper:

Image

The third point to emphasize is that the problem of dual legitimacy might be especially problematic if the electoral systems of the two branches were biased in different directions. Speaker Boehner said in November, “Listen, our majority is going to get reelected… We’ll have as much of a mandate as he [President Obama] will … to not raise taxes.” Boehner was correct, but Republicans benefit from a rural-favoring skew in House districts. Boehner has a clear majority of members despite not winning a majority of the votes cast for Congress. As Nate Silver recently argued, “[I]ndividual members of Congress are responding fairly rationally to their incentives” given their specific constituencies. In opposing them, the President might also be responding fairly rationally to his incentives. (At least in the first term. I have no clue what second-term presidents’ incentives are. History books, I guess.)

In other words, no matter what the results of this negotiation, I see no reason to believe that things will get better. When you are asking yourself on that future date how the United States got into a constitutional crisis, remember that the system is inherently crisis-prone. One of these days we are bound to fall off the cliff.

Postscript: After writing this, I stumbled across this Matt Yglesias post from 2010, where he makes a very similar argument for an earlier period of dysfunction. So it goes.

Guest Post: Obamacare and The Divided Welfare State

By Alex Armstrong*

Reading Jacob Hacker’s The Divided Welfare State: The Battle over Public and Private Social Benefits in the United States, I was struck by how accurately it illustrated the struggle for universal health insurance in America. Even though it was published in 2002, I believe the book offers important insights into the contemporary debate around health care reform, particularly why it took so long to happen and why it ultimately took the form it did.

Hacker begins with a pair of questions that have troubled social justice advocates for the last century. First, he asks: “Why are public social programs in the United States less generous, less complete, and less integrated into national economic policy than those typically found abroad?” And, additionally, “Why is the United States the only affluent capitalist country that does not guarantee universal or near-universal health insurance?”

Hacker critiques the way other scholars have answered this first question. Many of the techniques used to estimate the generosity and completeness of the American social programs are inaccurate, he says, because they ignore the structure of the U.S. welfare regime. Much of American welfare provision is actually conducted by the private sector, with the government encouraging the growth of private pensions and fringe benefits through tax expenditures and subsidies. Thus, simply comparing the percentage of GDP spent on social programs across countries will obscure the unusual American case. When these tax expenditures are considered alongside direct social spending, the U.S. rises to slightly above-average among developed nations.

But this unique structure poses a riddle of its own: why does the United States have a “divided welfare state?” Furthermore, the division isn’t uniform – why do we observe a universal federal program for retirement pensions but no equivalent for health insurance?

The answer is not simply American exceptionalism. “Let us cease to conceive of outcomes as rooted in national identities,” Hacker says. And indeed, this is not a story of rugged individuals without need or desire for government intervention.

Instead, the American state exists in its divided form as a result of the type of institutions which existed at the critical juncture when reforms were possible. According to Paul Pierson (2000), “Political development is punctuated by critical moments or junctures that shape the basic contours of social life.” Hacker’s book details these critical junctures to explain the divergent paths of pension plans and health insurance.

The critical juncture in American politics arrived with President Franklin D. Roosevelt and the New Deal. Social Security – direct government provision of retirement pensions – was possible because the private sector occupied only a “supplementary” role at the time. Before the New Deal, private pensions were rare and often restrictive (they were often, for example, revoked for workers who went on strike). These pensions were used chiefly as career incentives and funded solely by employers: workers had no “moral claim” to collect benefits, and at least one study suggests fewer than 10% of workers ever did. This supplementary role allowed the reformers to build a core role for government in the provision of retirement pensions. And because they had only provided fringe benefits, employers were able to accommodate themselves to the new government program: their private pensions continued to play a supplementary role after the introduction and expansion of Social Security.

In contrast, New Deal reformers were uneasy about any attempt to provide government health insurance. Blue Cross and Blue Shield had been expanding in the years prior to Roosevelt’s inauguration, and had already obtained favorable tax treatment in many states. The private sector was occupying a “core” role in the provision of health care insurance, and would not relinquish its position easily. An industry – complete with interest groups and entrenched institutions – had sprung up around insurance provision, and it left little room for the government to act. Additionally, the power of groups like the American Medical Association helped stymie any momentum for reform, and the critical juncture closed without any serious attempt at a government health insurance program.

In the years that followed the Great Depression, the relative positions of government and the private sector were reinforced through a process of increasing returns. Just as employers grew accustomed to providing fringe benefits above and beyond Social Security, the government learned to work at the edges of a private health insurance industry. Even Medicare, though it signified an expansion of federal authority, helped the private sector by removing high-risk individuals from private insurance pools.

In some ways, then, Obamacare represents the government’s final acceptance of its supplementary role. A true public option – “Medicare for all” – was an unrealistic goal, if Hacker’s analysis is correct. Instead, Obamacare provides government-backed incentives and penalties that bring Americans into the private insurance industry. Far from the government takeover of medicine that its critics claim it to be, President Obama’s signature legislative accomplishment may be the ultimate accommodation to America’s uniquely divided welfare state.

Affirmative action in Brazil: the challenges of racial classification

It’s old news that Brazil is enacting social quotas – both socioeconomic and racial – for public higher education. In my earlier post, I detailed the impact this sort of policy could have on the quality of higher education.  However, before I had the chance to write a follow-up to that post, a new piece of legislation began being drafted to introduce affirmative action to the civil service.

This is not the first policy of its kind in Brazil. Yet, it is too soon to discuss the implications and effects of this law. Regardless of the final shape the bill takes, any affirmative action will have to grapple with the basic issue of identification of the beneficiaries.

In Brazil, racial classification has always been a contentious topic. For many decades, the government refused to even collect racial information, arguing that race was not a salient issue on this side of the Americas.  However, even if one agrees that there is racial discrimination in Brazil, and that part of the country’s huge inequality hinges upon race and not only class and education, the issue of racial classification is not something to be quickly dismissed. A recent New York Times  forum, for instance, shows very different perspectives.

On the one hand, Peter Fry, a leading anthropologist, argues: “[…], unlike the U.S., the majority of Brazilians do not classify themselves neatly into blacks and whites. In Brazil, therefore, eligibility for racial quotas is always a problem.”

On the other hand, Antonio Sergio Guimarães, a leading sociologist fights back:

Perhaps the biggest challenge in Brazil is the temptation to introduce a systematic verification of self-declared color or race to prevent fraud in affirmative action programs. Race and color are social constructs. It is impossible to define their borders scientifically. Passing is something inherent to this kind of classification. It can be motivated by selfish economic protection or by political altruistic reasons. The fear of fraud must be restrained to give a chance to these programs to flourish.

Ultimately, these scholars seem to be discussing an empirical and methodological issue of racial classification with wide implications for redistribution. Despite the known complexities of racial classification, much analysis relies on a single self-classification based on fixed, mutually exclusive, choices.

Bailey, Loveman and Muniz (2012) present an interesting analysis of Brazil’s racial make-up and racial inequality, taking different racial classification schemes into consideration:

They demonstrate that very different pictures of Brazil’s racial make-up are created depending on which scheme is followed. Comparing the most extreme cases, Brazil could be either 70.4% or 40.7% White. Beneficiaries of affirmative action could either comprise 29.6% or 59.3% of the population. These are hugely different percentages.

Furthermore, these different measurements are not necessarily robust.  Even if more than one measure is used, there is still a lot of incongruence.

In their paper, they go on to convincingly show that different measures also imply different mappings of income inequality between those groups. Their findings do not necessarily challenge the finding that Blacks are, on average, worse off than Whites, but they do bring more precise, rigorous, and contextual evidence to support that claim. In any case, these findings do not mean that race should be disregarded and that it does not influence social interactions in Brazil. They argue that these different measures provide more evidence that race is a multi-dimensional social construct and should be analyzed as such – there is no “true race” to be measured.

But, what do these findings tell us when discussing redistributive policies based on race? Do these inconsistencies hinder any systematic implementation of affirmative action? Or are inconsistencies (and, to some extent, fraud) a “lesser-evil”, with affirmative action a good idea despite these issues? The recent policies seem to have embraced affirmative action despite these problematic measurement issues. The consequences of these choices are still to be fully understood.

Romney-ology and Afghanistan

Afghanistan was mentioned a total of four times during the GOP convention and only once on the final night, by actor Clint Eastwood. The Oscar winner chided President Obama for making the same mistake as the Russians for believing that the war in Afghanistan was “okay” and “something worth doing.” This absence was notable, with the Associated Press reporting it as the first omission of war by a Republican candidate in an acceptance speech since 1952. Neoconservative and ardent Republican William Kristol and Obama campaign guru David Plouffe both found the absence of any mention of Afghanistan regrettable. It probably did not help matters that Romney had said in a January 2012 primary debate that he thought President Obama talked insufficiently about Afghanistan and Iraq given the sacrifices being made by U.S. troops.

The Romney campaign countered that their candidate had talked about Afghanistan in his address to the American Legion the previous day. Here are the three sentences from that speech:

In Afghanistan, the President has chosen to disregard the counsel of the generals on the ground. I don’t know of a single military advisor to President Obama who recommended the withdrawal plan the President chose, and that puts the success of our soldiers and our mission at greater risk.

What would counterfactual President Romney have done about the war in Afghanistan? Well, candidate Romney agreed with the Obama administration’s initial deadline of December 2014 as “the right timetable for us to be completely withdrawn from Afghanistan, other than a small footprint of support forces.” Where he disagreed was in bringing “surge” forces home in 2012, prior to the end of the fighting season in the approaching winter months. This critique of President Obama for overriding the advice of his generals has been a recurring theme in Romney’s speeches and debate performances since he announced his candidacy in June 2011 in New Hampshire and the August 2011 Republican primary debate in Ames, Iowa. In fact, a quick review of Romney statements in Republican debates and elsewhere demonstrates that this is by far his most common statement regarding Afghanistan. Given Obama has made this apparently flawed decision, it is unclear what is to be done. Romney has not advocated re-surging troops, but instead stated only that he would bring troops home based on the advice of his generals, rather than politics.

The other area of relative clarity in a Romney Afghan policy is his opposition to negotiation with the Taliban, at least so long as they are killing American soldiers. His preferred end-state with regard to the Taliban has been to “defeat them” or “beat them.” Romney’s word choice was a public repudiation of his foreign policy advisor Mitchell Reiss’s limited endorsement of talks with the Taliban.

Not to be too pedantic, but the word choice on Mitt Romney’s campaign website today is instructive that President Romney might be more flexible on this matter than his primary season rhetoric indicated. The website states,

Our mission in Afghanistan is to eliminate al Qaeda from the region and degrade the Taliban and other insurgent groups to the point where they are not existential threats to the Afghan government and do not destabilize Pakistan, with its stock of nuclear weapons. Our objective is to ensure that Afghanistan will never again become a launching pad for terror and to send a message to any other nation that would harbor terrorists with designs on the American homeland. (emphasis added)

Drawing on different data points, the Center for a New American Security’s Andrew Exum has similarly concluded,

In the end, I expect a Romney administration to bite the bullet and negotiate, while claiming that his hard-line campaign rhetoric was meant to avoid giving the Taliban an impression of weakness. He can claim, in other words, that he was merely playing hardball in the run-up to negotiations.

Based on his public statements, it seems Romney does not talk much about Afghanistan because his policy going forward is not substantially different from President Obama’s. Perhaps this policy similarity is driven by both camps’ dispassionate review of the current situation. Or perhaps it is driven by the fact that the war is wildly unpopular, even among Republicans (e.g., Clint Eastwood).
