1. The city of Delhi has some of the very worst air pollution in the world. One key source of that air
pollution are motor vehicles. The city is contemplating ways to reduce air pollution from motor
vehicles. Suppose they know that the marginal benefits of abatement are equal to MB(a) = 154 -
10a, which comes entirely from health benefits to the local population. There is no uncertainty
about the benefits of abatement.
a?According to the Weitzman model, which policy will have a smaller expected deadweight loss,
the quantity policy or the price policy? (2 points)
b?To verify this prediction of the model, calculate the four possible deadweight loss values that
correspond to the four possible cases. The four cases are (high cost, price policy), (low cost,
price policy), (high cost, quantity policy) and (low cost, quantity policy). Was your prediction
correct about which policy is more efficient? (5 points)

United airlines canceled its flights to India's capital on the grounds that of bad air satisfactory.
Visibility used to be so bad that cars crashed in pileups on highways and trains had to be delayed
and canceled.
The airborne particles and poisonous chemical substances that make up the smog have choked
the 19 million residents of the metropolitan discipline, where merely respiration the air used to
be, at its worst, like smoking 50 cigarettes in a day. Hospitals suggested a 20 percent surge in
sufferers with pollution-associated diseases, and doctors have declared a public health
emergency.
Delhi chief minister went so far as to call his metropolis a gas chamber

web publication post how she developed a major respiratory illness and had to decamp to South
India. I´m used to living in paradise and out of the blue India has become a danger to my
wellbeing and the wellbeing of my associates and colleagues she wrote.
Greater than an inconvenience, air pollution is certainly a important medical hazard. The Lancet
commission on pollution and health stated 9 million premature deaths stemming from air
pollution in 2015. Greater than 2.5 million of those deaths had been in India, essentially the most

2. in any single country.
The air satisfactory index was once at 326 a ways beneath the peak on November eight, however
still within the Hazardous category. But Delhi isn't out of the woods. The industry normal
experiences that Delhi environment Minister Imran Hussain warned in a letter that ...Ambient air
best could as soon as again worsen within the coming weeks.
this is the third year in a row that air pollution in Delhi has grow to be very extreme, despite the
Indian Supreme courtroo try and mitigate it in October with a fireworks revenue ban ahead of
Diwali, the competition of lights.
Measuring Delhi's air against some of the different most polluted cities on the planet,
nonetheless, is intricate. Now not everybody tracks air pollution as well neither is it tracked by
the same metrics. The world wellness organization, for instance, ranked Zabol, Iran, as having
the worst particulate air air pollution in the world, however that was an annual usual, the number
was once from 2012, and it used to be extrapolated from a further size.
World health group
in the meantime, the easiest everyday particulate air pollution document was once set in
Shenyang, China, back in 2015.
So why did it get so unhealthy in Delhi this 12 months? Seems this oppressive smog is a pungent
mixture of an historic farming technique and the residues of contemporary city dwelling.
However the Indian executive has also failed to seek out ways to manage the well-understood
sources of pollution, which has allowed the quandary to grow progressively worse over time.
How Delhi"s air obtained so poisonous, and why it gained go away
you'll discover India's pockets of pollution in this live map from Berkeley Earth, an impartial
research consortium.
The map indicates airborne concentrations of particles with diameters of 2.5 microns or less,
sometimes called PM2.5. These particles can come from one-of-a-kind sources diesel exhaust,
natural dirt, wildfires and can result in coronary heart attacks, strokes, respiration difficulties,
and melanoma as they penetrate deep into lungs. The concentrations are mentioned as
micrograms per cubic meter.
In line with the us Embassys measurements, air in New Delhi reached PM2.5 concentrations of
greater than 1,200 micrograms per cubic meter, 48 times the rule of thumb value centered via the
arena wellbeing institution. This is nonetheless wanting the file set in Shenyang, China, where
concentrations topped 1,400 micrograms per cubic meter.
You can see in this screenshot from November eight how Delhi became the epicenter of
hazardous air high-quality in North India:
probably the most things thats so intriguing is how the pollution just isn't contained within the

3. cities and it doesn't even appear to be coming from the cities, mentioned Elizabeth Muller, govt
director of Berkeley Earth.
Actually, a lot of the pollution is coming from farms in neighborhood states of Punjab, Haryana,
and Western Uttar Pradesh. With the rice harvest over, farmers are burning crop stubble mainly
the remnants of the rice crop to arrange the fields to plant wheat and return vitamins and
minerals to the soil.
