V, U Or L? Three Views - Barokong

Will the recovery be V shaped, U shaped or L shaped? The 1918 influenza stood in most economists' memories as the paradigm -- a short, small V shaped slowdown, despite massive mortality. But 1918 was different. People and public policy went about their business ignoring the death toll to a large extent. François Velde writes about the 1918 Influenza. Burns and Mitchell (1946, 109) found a recession of “exceptional brevity and moderate amplitude.” I confirm their judgment by examining a variety of high-frequency data. Industrial output fell sharply but rebounded within months. Retail seemed little affected and there is no evidence of increased business failures or stressed financial system... Interventions to hinder the contagion were brief (typically a month) Of course the fact that interventions were brief has a lot to do with the mildness of the recession. Still,  it was on this historical evidence that most economists thought in February that this might be the great vacation. I then use high-frequency cross-sectional data to confirm the visible but brief impact of the epidemic and of the intervention measures (closings of certain businesses) that were adopted at the time. Banking data shows a financial sector functioning as it should (increasing loans). Conspicuously, there is no evidence of stressed balance sheets in the nonfinancial sector: business failures were on an uninterrupted downward ekspresi dominan, and cross-sectional data fails to find any effect of mortality.... Here is the picture of a short sharp V shaped 1918 -- followed by the deeper but equally V shaped 1921, not influenza related And here is the absence of business failure, all before the CARES act, stimulus, massive Fed lending, and so forth. François constructs an index of local business conditions from weekly qualitative reports and use it, along with measures of payments volumes, to examine if the speed with which economically costly interventions were put in place made a difference in economic outcomes. I find clear evidence that interventions changed the dynamics of the epidemic and affected economic activity by reducing the number of infected, though broader effects (through a reduction in demand or activity) proves elusive. Things are not always the same [Interventions] imposed mostly by cities but sometimes at the state level, took a wide variety of forms ranging from shutting down public gatherings and crowded places to staggering business hours, closing schools, imposing quarantines for infected people, requiring masks, etc. No intervention went as far as closing non-essential businesses, as have the lockdowns of the 2020 pandemic. Velds goes on to make an important point. There are lots of pandemic macroeconomic models being built at breakneck speed right now. They should fit not only this one -- a massive recession -- but also fit the milder earlier ones. ************* Sergio Correia, Stephan Luck and Emil Verner writePandemics Depress the Economy, Public Health Interventions Do Not: Evidence from the 1918 Flu Looking across the US, more exposed areas experience a sharp and persistent decline in economic activity. The estimates imply that the pandemic reduced manufacturing output by 18%. ... This differs a bit with Velde. In part they emphasize the longer lasting cross sectional effects, but I'm not sure if that totally accounts for the difference. We find that cities that intervened earlier and more aggressively do not perform worse and, if anything, grow faster after the pandemic is over. Our findings thus indicate that NPIs not only lower mortality; they may also mitigate the adverse economic consequences of a pandemic. This is surely true. The way to nip exponential growth in the bud is to stop it early. ************ Scott Baker, Nick Bloom, Steven J. Davis and Stephen J. TerryCOVID-Induced Economic Uncertainty are much more pessimistic. They use their measures of economic uncertainty, derived from newspaper reports and (panicked) financial markets, fed through a model that relates uncertainty to economic outcomes, to forecast a long, deep recession. Here too, the past may or may not be a guide to the future. The hope is for a swift all-clear, people return to the jobs they had and businesses reopen, without the agonizingly slow dynamics of a usual recovery. Well, that's the hope. ************** Robert J. Barro, José F. Ursua, Joanna Weng "The Coronavirus and the Great Influenza Epidemic" look across countries, Regressions with annual information on flu deaths 1918-1920 and war deaths during WWI imply flu-generated economic declines for GDP and consumption in the typical country of 6 and 8 percent, respectively The death rates were enormous relative to now 150 million deaths worldwide when applied to the world’s population of around 7.5 billion in 2020. and they note that we are choosing much more economic dislocation to save lives. However, extreme mitigation efforts—such as widespread cancellations of travel, meetings, and major events—will themselves contribute to the depressed economic activity. I'm not sure what implications to take for our question. **************

Probable Asteroid (Apophis) Impact

After its discovery in 2004, astronomers gave the asteroid Apophis a 2.4 percent chance of hitting the earth during its close flyby on April 13, 2029. If the 1,066-foot (325 meters) asteroid were to strike our planet, the blast could equal hundreds of megatons. Fortunately, further analysis showed that Apophis will miss the Earth by 19,400 miles (31,300 kilometers) in 2029. Extrapolating further into the future, another approach in 2036 is an even bigger miss. Apophis has only a one in a million chance of hitting Earth on that pass. Originally given a 1 in 37 chance to hit Earth, the near Earth object Apophis caused a bit of a panic in late 2004 with a high probability to hit Earth in 2029 or 2036. But what would happen if such a massive object collided with mother Earth? Don't even bother comparing it to a nuclear bomb because it's way beyond that.

Thrust Faults: Forecasting Megaquakes

Can slow creep along thrust faults help forecast  megaquakes? Summary : In Japan and areas like the Pacific Northwest where megathrust earthquakes are common, scientists may be able to better forecast large quakes based on periodic increases and decreases in the rate of slow, quiet slipping along the fault. Diagram showing the edge of the continental plate on which the island of Japan sits (green). At the Japan Trench (right edge), the Pacific Plate (orange) pushes under the wedge-shaped Japanese plate, driving west and downward in quiet slips at a rate of about 8 cm/year. Some places (locked areas) get stuck, however, with small locked areas generating repeated small quakes and larger locked areas generating larger quakes. The new study found that an increase in the frequency of these small off-shore earthquakes presaged larger quakes, including the 2011 Tohoku-oki quake. Credit: Image courtesy of University of California, Berkeley This desire comes from a merk new take a look at by using Japanese and UC Berkeley seismologists, looking at the ekstrathan 1,000-kilimeter-lengthy fault off northeast Japan in which the devastating 2011 Tohoku-oki earthquake originated, generating a tsunami that killed hundreds. There, the Pacific Plate is trundling underneath the Japan plate, not only inflicting megaquakes just like the value 9 in 2011, however giving rise to a series of Japanese volcanoes. The scientists studied 28 years of earthquake measurements, looking at quakes of value 2.Five or more among 1984 and 2011. They observed 1,515 locations off the coast of Japan in which small repeating earthquakes appear -- 6,126 quakes in all. According to co-writer Robert Nadeau, a UC Berkeley seismologist and a fellow with the Berkeley Institute for Data Science (BIDS), an analysis of those quakes discovered that large, more negative earthquakes -- those of significance 5 or extra -- happened tons tambahanoften while the periodic gradual-slip changed into fastest. This blanketed the brilliant Tohoku-oki earthquake, which additionally devastated a nuclear electricity plant and led to extensive radioactive contamination. "The endurance of the periodic pattern through the years may additionally help us refine earthquake chances in the destiny with the aid of taking into account the instances of predicted sluggish-slip pulses," he stated. "Right now, seismologists gives forecasts on a 30-12 months time body and anticipate nothing is converting on a shorter time scale. Our look at points out that things are converting, and in a periodic way. So it could be possible for scientists to offer shorter time levels of greater and lower opportunity for larger activities to manifest." The research was led with the aid of Naoki Uchida, a seismologist at Tohoku University, and included UC Berkeley seismologist Roland Burgmann, professor of earth and planetary science. They posted their findings inside the Jan. 29 trouble of Science. Story Source: The above post is reprinted from materials provided by University of California, Berkeley .

Geoengineering Fun - Barokong

Eli Dourado writes of four intriguing geoengineering schemes: (HT Marginal Revolution's incomparable links.) 1. Bring back the Wooly Mammoth The short version: Siberia used to be grassland, maintained by wooly mammoths. Grassland is colder than forests. Our ancestors killed off the wooly mammoths, and the trees took over. The permafrost is melting, which will be a huge climate amplifier. What to do? Nikita Zimov ... is director of Pleistocene Park, a 144 km² grassy Siberian reserve founded by his father, gonzo scientist Sergey Zimov. The Zimovs have spent the past two decades ripping up trees and reintroducing grazing herds, including bison, moose, wild horses, yaks, and reindeer. The plan is working. Nikita Zimov says the permafrost, which is at around –3º outside the park, is 17º colder (!) inside the park. Better yet bring back the wooly mammoth! Or rather play with elephant and wooly mammoth DNA until we get a half way new animal that can go restore the Siberian grasslands, and let it evolve a bit. Mammoths provided the Pleistocene with the valuable services of grazing, trampling snow and moving it around to get to the grass below, and uprooting trees. Nothing will make a mammoth happier, it is thought, than ripping a tree out of the icy ground, just as modern elephants enjoy doing the same in the warmer ground of Africa. Based on everything we know, mammoths were a critical part of the Siberian Steppe ecosystem, and their extinction at human hands is what caused the forests to take hold. I love the image of genetically engineered half wooly mammoths playfully ripping trees out of Siberia, eating grasses, and trampling ground to save the permafrost. 2. Project Vesta. mine large volumes of a (usually) green mineral called olivine, crush it up, and spread the resulting green sand on beaches all over the world, especially in the tropics where the water is warmest. It soaks up carbon dioxide and ends up on the sea floor, and eventually subjected into the mantle. That's where carbon dioxide ends up now, just much faster. And green beaches are kinda cool. ...One ton of olivine applied in Vesta’s process removes around 1.25 tons of CO₂ from the atmosphere. Olivine is superabundant, making up about half of Earth’s upper mantle...[ calculation follows ] that works out to around $9.04 per ton of CO₂ removed from the atmosphere and ocean. $10 per ton is a great price. Many other hot ideas are $100 per ton or more. what if we wanted to offset cumulative anthropogenic emissions since 1751? As of 2017, that was close to 1.6 trillion tons of CO₂. 1.6T × $9.04 = $14.46T through 2017. Adding $360B for each of 2018 and 2019, we arrive at a one-time cost of $15.18T for offsetting all human emissions since the dawn of the industrial revolution, which if done over 10 years, would cost 1.7% of global GDP. 3. Prometheus fuels Short version: a chemical process that allows you to create ethanol and then other fuels from any electricity source, including nuclear, solar, etc. Fuels can be stored and transported, so the intermittent nature of much "clean" fuel doesn't matter. 4. The billion oyster project Bring huge oysters back to New York Harbor. Ok, not much climate action but pretty cool ******* Cool, but like other sensible adaptation and geoengineering projects, you can tell this is going nowhere in today's environmental politics, right? Genetically engineer a new frankenspecies of mammoth and set it loose to breed? Spread green rocks on all the worlds beaches? How unsightly! You've got to be kidding right? Well, no, if the climate really is a planetary emergency. Two little sentences from Eli are worth quoting here: Some environmentalists don’t like geoengineering because it seems too easy: Indeed. Suppose we found a technical solution that did not require an uprooting of all society, "climate justice," a federal takeover of this that and the other. (Nuclear power, GMO foods, green beaches, and wooly mammoths.) How would the Green New Dealers react? Thanks, persoalan solved, we'll go back to other things? I doubt it. Most deeply it ignores the sins of humanity, for which we must atone. That is indeed much of the mood on the climate left -- and the reason all sorts of technocratic solutions are going nowhere politically. Eli makes a brave ethical argument for his GMO wooly mammoths: ..our climate impact started much earlier, during the Paleolithic masa, when we hunted megafauna to extinction and therefore altered critical ecosystems. .. But in fact, using genetic engineering to revive megafauna that we wiped out to restore ecoystems that benefit the climate also atones, if that is the right way of looking it at. Hunting these magnificent creatures to extinction was our original climate sin. Good luck with that. Maybe we should instead charge the mammoth head on: just get past the atoning for sins business and get on with solving the carbon duduk perkara in the most effective way.

Potong Extender USB lebih kurang 5 cm dari kepala ke-2 konektor. Lalu Kupas masing-masing kabel berwarna-warni sampai terlihat tembaga nya, ulir masing-masing ujung kabel UTP sampai tampak masing-masing tembaga nya. Hal spesial ini terdapat di rangkaian kabel berwarna-warni. Sambungkan 1 kabel hijau (UTP) dengan kabel hijau (dari USB). Campur 1 kabel Hijau Putih (dari UTP) dengan kabel putih (dari USB). Campur 2 orange putih Kabel (dari UTP) dengan kabel merah (dari USB). Paling selesai menggabungkan pertama 4 putih-coklat kabel serta biru-putih dengan kabel UTP hitam pada USB. Sesudah semuanya terhubung, isolasi supaya tak berjalan korslet. Imbuhkan pelindung untuk modem dari panas serta hujan (jika ditaruh diluar ruangan) misalnya dengan paralon atau kaleng. atau langkah memperkuat sinyal modem lain dengan menggunakan CD serta kaleng bekas : Untuk menambah tanda modem GSM serta CDMA Anda ada satu langkah lagi yang simpel dengan menggunakan sepotong CD serta kaleng semprot obat nyamuk langkahnya : Siapkan botol semprot penolak serangga atau pengharum., maka bakal memengaruhi tanda penangkapan. Siapkan cakram CD yang dipakai. Masukkan cakram CD pas dibawah modem Anda dengan posisi muka mengkilap pada modem. Gunakan kaleng akrab disc CD, tak perlu untuk terkait. Pindah-pindahkan kaleng seputar cakram sesuai sama dengan arah yang menangkap banyak tanda. Sesungguhnya terdapat beberapa lagi langkah memperkuat sinyal modem yang mampu anda pakai, namun langkah simpel diatas supaya mampu menemukan keuntungan.
