Abhijit Banerjee and Esther Duflo won the 2019 Nobel Prize in Economics for their “experimental approach in alleviating global poverty”. Their experimental approach encompassed a variety of novel methods to understand and analyse interventions and Randomised Control Trials (RCTs). Their research has been used by policy makers to make informed policy decisions to best help the marginalised.

What are RCTs?

To understand the effect of a policy, intervention, or medicine, decision makers try to measure the efficacy of the treatment. Do deworming pills given to children improve test scores? Does providing chlorinated water improve the health and economic outcomes of villages? These are some causal (read causal, i.e. caused by, not casual) questions researchers are interested in. The best way to analyse causal effects is to randomise the selection of people in the treatment and the control group (for example: children who are given deworming pills versus children who are not given the pills). This random selection of the two groups removes many statistical biases that might affect the results.

RCTs in India:

Many of the RCTs performed by Banerjee and Duflo were in India. They involved short- and long-term impact assessments of various interventions, policies, models, and treatments. We look at a few RCTs implemented in India:

Teacher absenteeism rates:

Troubled by the low attendance rates (or high absence rates) of public-school teachers in India, Duflo assessed the impact of financial incentives on the absence rates of teachers in Rajasthan. The study monitored teacher attendance by cameras, which was tied to a financial incentive if the attendance was high. From a baseline absence rate of 44%, teacher absenteeism in the treatment group fell by 21%, relative to the control group. High teacher attendance caused child test scores to improve too.

COVID-19 and health-seeking behaviour:

In the context of COVID-19, Banerjee tested the effect of sending messages via SMS that promoted health preserving behaviour. The results were very positive. By sending a short, 2.5-minute clip to 25 million randomly selected individuals in West Bengal, the intervention i) found a two-fold increase in symptom reporting to village health workers, ii) increased hand washing rates by 7%, and iii) increased mask-wearing by 2%. While mask-wearing rates increased only marginally, the spillover effects (wearing a mask stops the virus from infecting more people) were moderately high and positive.

Asset Transfers and the Notion of Poverty:

An RCT by Banerjee in West Bengal involving a productive asset transfer accompanied with training found large and persistent effects on monthly consumption and other variables. The treatment group reported 25% higher consumption levels relative to the control group, who did not receive the asset transfer and training. Implications of such RCTs are huge. The notion that the poor are lazy and unwilling to perform strenuous labour is falsified by this RCT. Often, what the poor lack are opportunities that are hard to come by, given their financial status. A small nudge, like the asset transfer, can cause large and positive effects on their well-being.  

Salt fortification to reduce anaemia:

RCTs also help rule out less cost-effective interventions. Duflo and Banerjee evaluated an RCT which distributed fortified salt in 400 villages of Bihar, to reduce the prevalence of anaemia. However, this intervention found no statistically significant impact on health outcomes like anaemia, hemoglobin, etc.  Thus, while RCTs help introduce novel methods of impacting the lives of the poor, they also help in ruling out in-effective measures. A policy maker might try other alternatives to reduce the prevalence of anaemia.

Are RCTs the gold standard?

Maybe. Extrapolating results from a regional RCT to national policies could present problems. Contextuality matters. A study that indicates positive gains for one region might present different, and rather adverse effects for another region. Nation wide effects might not be as prominent as regional results of a single RCT. The good part is that Banerjee and Duflo have a solution. Just perform more RCTs!

Expat Exodus In The Middle East

The COVID-19 pandemic has hit people and economies worldwide, sparking a global recession and financially destabilising millions of people. In the Middle East, dipping oil prices have only worsened the threat to the economy. Businesses are shutting down, and many are trying to survive by cutting the salaries or laying off of workers. Large segments of the workers in these countries are expatriates, and many have struggled to make ends meet as unemployment soared.

The development of the Gulf countries has always been intertwined with their large expat populations. These workers are often vital to the economy, not just as part of the workforce but also as consumers by enabling successful malls, restaurants and other forms of recreation and tourism. Countries like Saudi Arabia gain valuable non-oil revenue in the form of increased Value Added Taxes (VAT) and by imposing a monthly fee on migrants who want to sponsor family members.

Many of these workers are from developing Southeast Asian countries such as India and Pakistan, and contribute greatly to their home country’s economy in the form of remittances, i.e sending money back home. Those who are facing unemployment or salary cuts are eager to be repatriated, especially since in many Gulf countries visas, rent, and even phone lines are linked to jobs, and expats have little to no social safety nets to fall back on.

Panicked” Indians applying to go back home crashed the Dubai aviation ministry’s website for applications in the process. The consulate says it has received around 200,000 applications for repatriation of expats from as many as 12 countries.

For some, closing businesses are forcing them to go home. For others, the cost of education is the major concern. The Emirates group, Uber’s Middle Eastern counterpart Careem, and hotels are some of the few major employers considering laying off large portions of their staff or reducing salaries.

Dubai has been one of the hardest hit, as expats form an estimated 92% of the population. Dubai based movers estimate that they’re getting up to seven calls a day to ship belongings abroad. It is extremely hard to gain permanent resident status in countries such as the UAE, and the costs of living and education are quite high and often provided by employers, which has made leaving the only option left for many laid-off workers across all fields.

The UAE has tried to offset the damage by granting automatic extensions to expiring work permits, waiving of work permit fees and fines, and providing interest-free loans and repayment breaks.

Meanwhile, governments in Kuwait and Oman are trying to mould the exodus into an opportunity to boost local employment. On the other hand, the Saudi Arabian government has been criticised for not taking enough measures to protect the local workforce.

While the Gulf countries have been trying to decrease their dependence on oil wealth and foreign workforce, it is not something that can be accomplished soon, especially given the great dependence of the Gulf economies on both those factors.

There is still too unavoidable a gap between the current skill of local workers and the training needed to compete with foreign professionals, making it hard to simply employ domestic workers in place of foreign ones. The pandemic, however, might not leave much of a choice.
