In his presidential campaign in 1928, Herbert Hoover promised to help impoverished farmers by increasing tariffs on agricultural products; after the election, he also asked Congress to reduce tariffs on industrial goods. In April 1929, well before Black Thursday, U.S. Representative Reed Smoot, a Republican from Utah, introduced a bill that passed the House in May. The bill increased agricultural and industrial tariffs at levels that had not been seen for a century. This was a relatively benign beginning of what would become one of the most tragic policy measures of the 1930s. Within a few months of the bill being passed in the Senate as the Smoot-Hawley Tariff Act, other countries in response raised their own trade barriers, which started a vicious circle of contracting world trade flows and economic activity, and rising unemployment from 1930 to 1933.

There are three main lessons from the policies mentioned above: 

1. “Beggar-my-neighbor” policies are bad.
2. Bad policies can have tragic consequences.
3. Beware of benign measures that can ignite uncontrollable chain reactions.

Indeed, these lessons have been in every policymakers’ mind since the Lehmann Brothers failure. In fact, the creation of the G-20 was a spectacular effort by the major economies of the world to cooperatively answer the challenges raised by the most severe financial crisis since the 1930s. The G-20 coordinated the management of strong macroeconomic policies, including huge deficits and easy monetary policies. These were bold decisions but not radical, and those who condemned government intervention have been rebutted by the urgency of these measures. And it is now widely acknowledged that these unconventional measures successfully avoided the transformation of the Great Recession into another Great Depression.

In the U.S., the recovery is at best shaky, unemployment is artificially reduced by the growing number of discouraged workers who have stopped looking for work, and the median income is dramatically lagging.

Today, there are reasons of hope that have been eloquently described by Roger Altman [1]: it can be argued that in the U.S., and to a lesser degree in Europe, the crisis has inspired significant reforms that have pushed the economy closer to a sound and sustainable growth trajectory. However others rightfull so object that enormous challenges are still facing the populations and their respective governments. The price paid for curing the damages of the global financial crisis is extremely high everywhere. In the U.S., the recovery is at best shaky, unemployment is artificially reduced by the growing number of discouraged workers who have stopped looking for work, and the median income is dramatically lagging. In Europe, austerity is the name of the game in every country except Germany and despair is growing among the populace. Japan has been stuck for two decades in deflation. Many citizens around the world feel that the efforts have gone too far, yet the benefits and retribution have benefitted too few. Electoral frustrations are on the rise as demonstrated in Italy where Mario Monti’s wise policies have been followed by the success of the Five Stars Movement of Beppe Grillo. Italy turning ungovernable is a bad sign for democracies. Could we see a comeback of desperate national policy experiments like the ones that democracies were progressively pushed to adopt after facing insurmountable difficulties in the early 1930s?

Now, a really radical policy experiment is already taking shape in Japan with the introduction of what has been named “Abenomics” after the name of the newly-elected prime minister, Shinzo Abe. It has taken only one election and one nomination at the head of the Bank of Japan to really revolutionize monetary policy. This revolution can be qualified in two ways, one benign, one threatening.

There is first reason to rejoice. After two decades of failed policies, it’s finally good to see bold politicians ready to do whatever it takes to extract Japan from its deflationary trap. Should Mr. Abe succeed, he would unclench the domestic brakes to economic growth, which deflation has so lengthily opposed: declining prices in effect are discouraging consumption (goods will be better and cheaper tomorrow, why spend now?) and investment (facing massive excess capacity of production and weak final demand, why invest now?). The new mission of the governor of the Bank of Japan is to raise inflationary expectations to 2 percent, which would make Japan converge with the world average inflationary trend and monetary policy. Demand would restart and Japan would contribute to an improved global economic outlook. This is the view that the IMF chief recently endorsed. As expected, Mr. Kuroda last week unveiled a much more aggressive package of quantitative easing than what we have previously witnessed, with a view to double the monetary base. Japan’s central bank will buy more long-term government bonds, pushing private investors to invest more in risky assets. Since the election, the Nikkei has risen 34 percent. Different polls and surveys suggest that the public is positively reacting to Mr. Abe’s promises.

Is success already underway? That would be good news for Japan and for the world. But it is clearly too soon to celebrate because this virtuous circle can simply fail to happen. No central bank until now has ever tried to raise inflationary expectations and no one knows if this can turn to be a practical and manageable reality. Inflationary expectations could also easily turn out of control. Before exercising traction on the economy, they could impose higher interest rates that would have devastating consequences for the Japanese Treasury in the management of a huge public debt (more than twice the size of the GDP). But there is something worse than the risk of Abenomics having poor or adverse domestic consequences.

The other side of Abenomics is currency management, a much less propitious theme for a government to communicate in the weeks leading up to the IMF Spring Meetings in Washington. This aspect of the policy is not only bold, it’s actually radical. As a candidate, Mr. Abe made extremely clear that he was willing to help the manufacturing sector by depreciating the yen and that monetary policy would be designed with this goal in mind. Remember that Japan, despite all its woes, remains a formidable exporter with an external surplus close to ¥650 billion in February (approximately $6.5 billion). As my fellow economists at Brookings have recently shown [2], the Japanese bilateral surplus with the U.S., which is $23 billion according to reported trade statistics, would dramatically increase by 60 percent and reach $36 billion if measured in added-value terms. Mr. Abe’s message was well received by investors who quickly after the election started to short the yen. As a result, the yen has slumped 21.5 percent in the past five months— the worst (or the best?) performance among the currencies of the developed economies. Following last week’s announcement that the Bank of Japan was really acting to debase monetary policy, the yen weakened beyond 99 yen per dollar and dropped against 15 major currencies.

A weakening yen also poses challenges for China, complicating the China’s strategy to reach its 8 percent target growth for this year; it could also trigger huge capital flows into China destabilizing the delicate control of financial stability

This is where Mr. Abe and Mr. Smoot cross ways: both are local politicians inspired by the difficulties facing their countries; both are willing to use every available policy tool to soften these difficulties; neither is willing to shock the global economy, which has never been the case when arguing in favor of protectionism or competitive devaluations. But these measures are nonetheless radical because they have the potential to ignite uncontrollable chain reactions. South Korea for one already declared itself very concerned by this aggressive policy, which is totally understandable. For instance, when Toyota and Sony take some advantage of Abe’s policy, the ones that would likely be first to suffer are Hyundai and Samsung. South Korea has vital interests at stake and, over In the last five months, it has been struggling with a pernicious appreciation of its currency. A weakening yen also poses challenges for China, complicating the China’s strategy to reach its 8 percent target growth for this year; it could also trigger huge capital flows into China destabilizing the delicate control of financial stability; SAFE, the financial institution that manages China’s huge official reserves, last week published its yearly report for 2012. Commenting on the global environment, the report emphasized that “a yen’s depreciation can’t solve Japan’s structural problem, … [but] could turn out of control and trigger a suspicion about its sustainability,… and finally have dangerous spill-over-effects”[3]. Chinese officials at the Boao Forum also expressed similar concerns.

We still don’t know the end. Hope is that we could see the positive interpretation of a bold Japanese policy experiment contributing to a better functioning world economy. Experience should nonetheless make us cautious. What the movement by the Bank of Japan does is to increase an already huge excess liquidity, inundating global markets. In addition, the Japanese government has added a dangerous touch of currency manipulation. Both aspects should be alerts for the IMF rather than too quickly fuel the artificial satisfaction of promises regarding higher inflationary expectations and increased domestic demand. In the end, competitive devaluations always prove inefficient and dangerous because they inevitably provoke reactions and retaliations. “Currency wars” have made headlines from time to time in the recent years but these were skirmishes. This time it could be for real, and this should be a major concern for the United States. It is a great thing that Japan recently expressed interest in joining the Trans-Pacific Partnership, but these are words with long delayed potential results. A more constructive and immediate task is to continue the cooperative global approach of exchange rate policies and to strongly discourage any temptation of national radical policy experiments. This should be a central issue next week during the IMF Spring Meetings in Washington.

Ahmet Davutoğlu, Turkey's new Prime Minister, is a familiar name in Western capitals. It is also a name that generates mixed feelings among his peers.

What most agree is that he is was an incredibly ambitious and hardworking foreign minister, always willing to travel wherever necessary, even when the outcome of such visits generated little concrete results. There is also consensus about his willingness to lecture his counterparts. He probably believed that his academic background and the relative ignorance of his counterparts entitled him to do so. But in most cases he had a tendency to forget that he was dealing with fellow foreign ministers and not students of history. This tendency generated only a begrudging sense of respect, even among his most graceful and objective peers.

It is also clear for people who knew him when he was an academic that politics has changed him. In the eyes of most his students, he was a reluctant policymaker when he began his political life. He often mentioned that his real goal was to go back to academia, where he could once again enjoy the intellectual life of an analytical thinker who can keep a healthy distance from events. Yet, in a matter of few years he discovered the irresistible pull of power. It was maybe "Kissinger syndrome" — realizing that power is the ultimate aphrodisiac.

Perhaps most important is the question of Davutoğlu's ideology. There are numerous articles written about this question, and the emerging consensus is that he is an incurable idealist. It may be reductionist to argue that he is an Islamist, but it is undeniably true that he has focused on parts of the world where Muslims are facing injustice with much enthusiasm. Although he rejects being labeled neo-Ottoman, it is also undeniably true that he speaks of Ottoman tradition, tolerance and governance with great nostalgia. As most of his students, he is very critical of the West and its Orientalism. His years in Malaysia as a professor bring a colorful interpretation to his critic of colonialism and imperialism. Yet, what he often fails to realize is that in his criticisms of the West, he often repeats the methodological fallacy of Orientalism. The result is what can be best labeled "Occidentalism" — a tendency to generalize and construct a Western civilization with a prejudice similar to the one displayed by Orientalists.

Finally, there is the issue of missing modesty. Although Davutoğlu appears to be very modest and unpretentious, he often displays a stubborn resistance in admitting mistakes. This is perhaps a defense mechanism in dealing with the press. But combined with his unabashed sense of idealism, his reluctance to recognize failure and to see the world as it is rather than how it should be is very troubling for a policymaker. The reluctance to admit policy failures creates two major problems: a disconnect from reality and an inability for course-correction.

In short, there is a lot of ambivalence towards Davutoğlu in the West. He is coming to his new position with a lot of baggage and the looming shadow of a powerful president. Newly elected President Recep Tayyip Erdoğan wanted someone who would follow his lead without hesitation. His choice speaks volumes about Davutoğlu's new persona and about how much he has changed since the early days of his political career.

This weekend’s election results in Turkey were a surprise to the vast majority of Turkish pollsters and pundits, myself included. The ruling Justice and Development Party (AKP) won nearly 50 percent of the popular vote. The party can now form a single-party government, even if it doesn’t have the supermajority necessary to remake the Turkish constitution. What happened?

As with much in life, the result does make sense in hindsight. Prior to the June 7 election, President Recep Tayyip Erdoğan and the AKP leadership had supported a Kurdish peace process, in part in the hope of gaining Kurdish votes. In that election, however, not only did the AKP fail to win new Kurdish votes, but support for the Nationalist Action Party (MHP)—a far-right Turkish nationalist party—swelled, apparently out of frustration among nationalist Turks with the AKP-led peace process with the Kurds. In other words, the AKP had the worst of both worlds.

Erdoğan and the AKP leadership, recognizing the political problem this posed for them, allowed the peace process to collapse amid mounting instability driven by the Syrian civil war. This, combined with disillusionment with the MHP leadership due to their perceived unwillingness to form a coalition government, drove about two million MHP voters to the AKP this weekend. The exodus shows, in a sense, what close substitutes the two parties can be among a more nationalist voting bloc.

The controlled chaos that resulted from the collapse of the peace process—combined with the escalating refugee crisis, the fear of ISIS attacks, and the struggling economy—helped the government politically. Voters evidently recalled that it had been the AKP that brought the country out of the very tough times of the 1990s.  

In contrast, the opposition parties seem to lack leadership and appear to promise only internal squabbles and indecisiveness. Craving security and stability, voters have now turned to the one party that appears to have the strength to provide it. In that sense, Erdoğan’s nationalist gambit—which was actually a well-conceived series of political maneuvers—worked. Even some one million conservative Kurdish voters returned to the AKP.

These voters perhaps did not notice the irony that the government had also engineered the instability they feared. In part, this success derives from government’s control over the media. These elections may have been free, in the sense that Turkish voters can cast a ballot for the candidates they want. But they were not fair. The state maintained tight control over traditional and social media alike. Freedom House and the Committee to Protect Journalists, among others, have cast doubt on Turkey’s press freedom credentials. Real opposition voices are difficult for media publish or voters to see on television. Thus, for example, Selahattin Demirtaş, the leader of the pro-Kurdish Peoples' Democratic Party (HDP) and the most charismatic opposition politician in Turkey, had essentially no air time during the campaign.

There are some important upsides to the election results. For one, HDP again passed the 10 percent threshold to remain in parliament. That will help mitigate—though hardly erase—the polarization that grips the country, and will hopefully make government reconsider its abandonment of the Kurdish peace process.

More significantly, the AKP does not have what it needs to convert Turkey’s government structure into a presidential system, which would be a bad move for the country. The election results will undoubtedly revitalize Erdoğan’s push for a presidential regime in Turkey. But that requires changing the constitution, and the AKP did not achieve the supermajority that it would need to do that on its own.

Critically, changing to a presidential system will require some support from the opposition and even more importantly popular support via a referendum. As political strategists around the world have learned, people tend not to vote on the actual referendum item, per se, but based on more general opinions of their leadership. So to win a referendum on the presidential system, Erdoğan and his AKP colleagues would need to show improvements in the economy, in the security situation, on the Kurdish issue, on Syrian refugees, and on national stability more generally. Instability in Turkey, particularly the renewal of violence in the Kurdish region, will deter investment and deepen the economic slump throughout the country.

With its new majority, AKP leaders are now in a position of strength to negotiate with the HDP over Kurdish issues. The refugee crisis also means the government also has more leverage with the EU. If it chooses to use its strength to reach positive agreements on those fronts, the outcomes could be very good for the Turkish people.

To actually win a referendum on the presidential system, Erdoğan would have to work to depolarize his country. While the presidential system itself would not be good for Turkey, the process of getting there might be.

Abstract

An individual-based computational model of smallpox epidemics in a two-town county is presented and used to develop strategies for bioterror containment. A powerful and feasible combination of preemptive and reactive vaccination and isolation strategies is developed which achieves epidemic quenching while minimizing risks of adverse side effects. Calibration of the model to historical data is described. Various model extensions and applications to other public health problems are noted.

Published version of the CSED October 2007 Working Paper

ABSTRACT

Background

In classical mathematical epidemiology, individuals do not adapt their contact behavior during epidemics. They do not endogenously engage, for example, in social distancing based on fear. Yet, adaptive behavior is well-documented in true epidemics. We explore the effect of including such behavior in models of epidemic dynamics.

Methodology/Principal Findings

Using both nonlinear dynamical systems and agent-based computation, we model two interacting contagion processes: one of disease and one of fear of the disease. Individuals can “contract” fear through contact with individuals who are infected with the disease (the sick), infected with fear only (the scared), and infected with both fear and disease (the sick and scared). Scared individuals–whether sick or not–may remove themselves from circulation with some probability, which affects the contact dynamic, and thus the disease epidemic proper. If we allow individuals to recover from fear and return to circulation, the coupled dynamics become quite rich, and can include multiple waves of infection. We also study flight as a behavioral response.

Conclusions/Significance

In a spatially extended setting, even relatively small levels of fear-inspired flight can have a dramatic impact on spatio-temporal epidemic dynamics. Self-isolation and spatial flight are only two of many possible actions that fear-infected individuals may take. Our main point is that behavioral adaptation of some sort must be considered.”
