Certainly one of my favorite books of the 12 months was Randall Munroe’s What If? 2, which like its predecessor presents critical scientific solutions to absurd hypothetical questions. For instance, “What would occur if the photo voltaic system was crammed with soup out to Jupiter?” The brief reply is nothing good. Munroe’s extensively researched reply begins merely with “Please ensure that everyone seems to be safely out of the Photo voltaic System earlier than you fill it with soup.”
Or, what would occur when you put in a big iron dice cooled to absolute zero in your lounge? (In case you can keep away from the chance that liquid oxygen collects like dew on the dice’s floor, then units your home on fireplace, you’ll be effective. Simply don’t lick the dice.)
Impressed, I took to Twitter to ask folks for his or her absurd hypothetical questions concerning the financial system, to which I would try critical solutions. This column is simply too brief — and this columnist insufficiently gifted — to do justice to Munroe’s books. But I need to attempt; these absurd hypothetical questions aren’t going to reply themselves.
What does the world appear to be if all financial transactions are actually performed with solely penny cash? — Stuart Langridge
The apparent drawback is that your purse would turn out to be relatively heavy. The British penny weighs 3.56 grammes; put one other manner, £2.81 weighs a kilogramme. Most merchandise would weigh considerably lower than the cash required to purchase them. A grocery store store costing £100 would require 35.6kg of pennies, so be sure to park subsequent to the purchasing trolleys. All this is able to be inconvenient. Individuals would possibly begin to determine workarounds. What would possibly they do? Historical past presents a clue.
A couple of thousand years in the past, the residents of Sichuan, China, had been ordered to make use of cash fabricated from iron. (Sichuan was a frontier province, and China’s rulers didn’t need gold and silver circulating round Sichuan, presumably leaking into overseas lands.) Sichuan’s residents instantly confronted the penny drawback, particularly that hardly something weighed greater than the iron cash you would wish to lug round to purchase it. Slightly than pushing round wagonloads of iron cash, retailers would write IOUs, promising to settle their payments later when it was extra handy for everybody.
Then — this step is clear in hindsight — folks began paying for issues by passing across the IOUs. If the broadly revered Mr Zhou purchased one thing from my store and wrote me an IOU, then after I went to your store later, I might write you an IOU in flip. However you would possibly choose it if I gave you Mr Zhou’s IOU as an alternative. In any case, we each know that Mr Zhou all the time pays his money owed. Now you and I, and Mr Zhou, have collectively created a form of paper cash. It’s a promise to repay that has a marketable worth of its personal that may be handed round from individual to individual with out being redeemed with these tiresome iron cash. I believe that if we had been pressured to undertake Stuart’s “pay in penny cash” system, we’d invent paper or digital options simply because the Sichuanese did, and be again the place we began.
What if we had not a minimal wage however a most wage? — Rachel Wrangham
The perennial concern with a minimal wage is that it would destroy jobs. Oddly, the utmost wage might have the identical impact. In each circumstances, staff and employers must discover a candy spot in wage negotiations: a wage that’s excessive sufficient to draw the employee, however low sufficient to be worthwhile for the employer. An issue with each minimal and most wages is that the candy spot could also be unlawful — by which case the job gained’t exist. Both it’s unprofitable for employers, or unattractive for the employees. Oops.
Wage guidelines additionally change the facility dynamic within the office. Minimal wages put extra bargaining energy into the fingers of staff. A authorized wage most would put extra bargaining energy into the fingers of employers. It would nicely improve company earnings whereas lowering celebrity salaries. I believe that extremely paid staff would attempt to discover loopholes, for instance, within the type of self-employment. However then self-employment has been a loophole for avoiding the minimal wage, too.
What would occur if tax wasn’t a factor? — John Cronin
The speedy consequence can be that we’d have to search out one other technique to pay for, or go with out, issues reminiscent of the military, the police, roads, the NHS, faculties, state pensions and repaying public debt. For a touch at what this would possibly appear to be, choose up a British newspaper this month. In fact it might be extra intense than that. UK authorities debt can be repudiated, pensioners would return to work or beg for alms, and healthcare and education can be paid for in the identical manner as meals and housing — out of individuals’s personal pockets.
Many individuals may be stunned at how little distinction such a radical change made to their lives. What they saved in taxes, they’d pay as an alternative on visits to the physician or faculty charges. However an enormous quantity of redistribution is quietly performed via public spending, so the nation can be full of people that couldn’t afford healthcare, education, highway pricing, pensions or a lot of the rest.
And a few issues simply don’t lend themselves to consumer charges. The Meteorological Workplace might most likely pay for public climate forecasts via voluntary contributions, but it surely’s unclear that you may pay for the military, navy and air pressure just by having a whip-round.
A radical different is to pay for public spending by printing cash. This could trigger inflation, and eat away at everybody’s spending energy. At a primary approximation, it ought to price residents about as a lot as their taxes would have finished. The burden would fall otherwise, although. Individuals with massive money holdings or nominally fastened incomes would lose most. Those that held tangible property or had been simply in a position to maintain their wealth in foreign currency echange would lose the least.
Making an attempt to pay for all current public spending by printing cash can be disastrous pretty shortly. Within the UK, the federal government is answerable for about half of all spending within the financial system, so firing up the printing presses would quickly trigger chaotic hyperinflation. But when public spending had been dramatically diminished, and well being, schooling and different providers had been supplied on a fee-for-service foundation, then maybe the printing presses might resolve that nagging query of find out how to pay for the military. In abstract: ensure that everyone seems to be safely in a foreign country earlier than you abolish all taxation.
What would occur if everybody in Coventry was given £1mn on situation they didn’t depart Coventry? — Neil Pattinson
Coventry would turn out to be the Qatar of the West Midlands. With everybody in Coventry abruptly changing into a millionaire, it might be laborious to influence anybody to do disagreeable work. Nonetheless disagreeable work would must be finished. That may imply persuading a brand new class of non-resident staff to commute into the town to do it — an association that’s more likely to show inefficient and costly. Throughout the metropolis’s boundaries, it might be absurd to attempt to produce something aside from Michelin-starred restaurant meals or luxurious spa therapies for Coventry’s unique residents. And the entire thing would finish in tears if the cash ran out. On the upside, Coventry would host a improbable World Cup.
