It’s difficult to think about how to spend money, and deciding money value in the future is almost impossible to many people. That’s because it is hard for us to consider the opportunity costs of objects we purchase.
A study was conducted with people who wanted to purchase a car to determine their ability to assess the opportunity cost of that purchase. When asked “If you buy this car today, what will you not be able to do in the future as a result?”, the majority said, “If I buy this SUV today, I will not be able to buy a sports car tomorrow.” Nobody said that he would not be able to buy 300 lunches at a restaurant because they were, though unconsciously, restricted within the car field, not even attempting to think of an item from another field.
The nature of modern spending makes things even harder by making money less concrete. If I give you $1,000 in an envelope each week, you will see in the shop that what you’re buying comes at the expense of other things of the same price. After all, you have the real experience because you have to hand out the real money note if you want to get the object. But with credit cards and loans, financial mechanisms have become increasingly unclear, making it more difficult for people to compare the value of spending now with the value of money in the future as they are allowed to pay for the purchases later.
Irrelevant influences and considerations, such as a person’s present emotions or preferences, can influence how much worth someone places on an object too.
In a study, Professor Dan Ariely and his team asked participants to determine the value of objects like wine, chocolates and electronics.
“We first told them to consider whether they would pay the amount equivalent to the last two digits of their social security numbers,” he says. “We found a significant relation between the amount they were willing to pay and these digits.”
For instance, someone whose social security number (SSN) ends in 25 valued the objects much lower than someone with the last two digits of 78. For no logical reasons, the test subjects leaned toward the most recent number they had access to when valuing the items. Even with full information about the objects, some people had no logical point of reference for the value of the objects. Instead, they used their own irrelevant experiences as references.

“If you want to make money in Cuba, buy garlic,” says a farmer in Artemisa province, in western Cuba. Garlic, known as “white gold” for its value, is critical to the unique seasoning of Cuban food.
Every year garlic-sellers on the streets of Havana peddle bulbs from backpacks, as if selling fake luxury handbags or electronics. The price of garlic tends to boom around November and December, before more comes onto the black market. A pensioner in one part of the capital complains that a bulb now costs 25 pesos ($1) and 450g (11b) costs 240 pesos, four times the price in September.
But the pandemic has worsened shortages of basic goods in Cuba, along with fertilizers, fungicide, seeds and supplies for animals. Thousands of rabbits died last summer in an outbreak of haemorrhagic disease. Pigs may be next.
A.Profiting from garlic is nothing new. |
B.Another way to get the bulbs is through garlic resellers. |
C.The country is on high alert following an outbreak of African swine fever in the Dominican Republic. |
D.Ministry of Agriculture of Cuba has been developed a program of plant breeding with the aim of obtaining adaptation to the country conditions. |

F.As with so many things on the communist island, however, it is in short supply. |
【推荐2】Britain’s meat industry on Friday warned that an upcoming shortage of carbon dioxide (CO2) could cause massive disruption (中断) to food supplies within two weeks.
The gas is used to stun animals before slaughter (屠宰) , in the vacuum packing of food products to extend their shelf life, and to put the fizz into beer, cider and soft drinks. It is also required for some medical procedures and used in the nuclear and semi-conductor industries.
Britain’s food supply chain, already creaking from a severe shortage of heavy goods vehicles (HGV) drivers and the impact of Brexit (脱欧) and COVID-19, is heavily reliant on fertiliser producers for CO2 which is a by-product of their production process. However, two of the largest fertiliser producers, Norway’s Yara YAR.OL and rival CF Industries Holdings CF.N, have restrained production due to a sudden increase in natural gas prices, which has in turn started to dry up CO2 supplies.
Nick Allen, chief executive of the British Meat Processors Association (BMPA), said that once current stocks of the gas run out, some meat companies will have to stop taking animals and close production lines, leading to a logjam of animals back to the farms. “We already have this situation in the pig industry which is now facing the disruption prospect of a humane killing on farms,” he said. The BMPA is persuading Business Minister Kwasi Kwarteng to help support UK CO2 production in the short-term.
“We are monitoring this situation closely and are in regular contact with the food and farming organizations and industry, to help them manage the current situation,” said a UK government spokesperson. “The UK benefits from having access to highly diverse sources of gas supply to ensure households, businesses and heavy industry get the energy they need at a fair price. Britain last suffered a major CO2 shortage in 2018, leading to some drinks wholesalers to ration (定量) sales.”

【推荐3】You might not regard England, which is famous for its almost year round rain, as a place with a water shortage problem. However, James Bevan, head of the UK Environment Agency, warned at a recent conference that England will lack water within 25 years.
A major reason for the shortage is climate change. As recently as 2017, Britain saw its driest 10-month period in over 100 years. In 2018, below-average rainfall caused many reservoirs (水库) to run dangerously low. It’s predicted that, by 2040, over half of UK summers will be hotter than the summer of 2003, and water supply from rivers could fall by between 50-80 percent, according to CNN. In 2003, the UK experienced one of the most significant heat waves in recorded history.
Another major reason is that the British waste too much water in daily life. On average each person uses about 140 liters of water per day through a combination of showers, washing machines and garden hoses, according to the BBC. Bevan said people should try to save water and that they could cut their daily water use from 140 to 100 liters. “There re simple steps we can take... Get a low flush toilet, Take short showers...” he said during the conference.
While England may not be the only place facing a water shortage, some other areas have taken measures to avoid one. Israel, for example, recycles waste water, which makes up 40% of the country’s agricultural water.
Wherever you’re in the world, water is precious. Our world is 70% covered by water, but only 2.5% of it is fresh, and only 1% is easily accessible. So let’s try to save the water we’re lucky enough to have and not be wasteful.

【推荐1】Although credit cards are becoming a more acceptable part of the financial scene, they are still regarded with doubts by many as being a major part of the “live now pay later” syndrome(综合症).Along with hire-purchase, rental and leasing schemes(租赁项目), they provide encouragement to spend more money. Of course, it is only the hotheaded who give way to the temptation to live, temporarily at least, beyond their means, and such people would no doubt manage to do so even without credit cards.
Advertising campaigns have, however, promoted a growing realization of the advantages of these small pieces of plastic. They prevent need to carry large amounts of cash and are always useful in emergencies.
All the credit card organizations charge interest on a monthly basis which may work out as high as 25 per cent a year, yet sensible purchasing using a card can mean that you obtain up to seven weeks, interest-free credit. Using the card abroad, where items frequently take a long time to be included on your account, can extend this period even further.
It is worthwhile shopping around before deciding on a particular credit card. It is necessary to consider the amount of credit granted; interest rates, which may vary slightly; the number and range of outlets(经销店), though most cards cover major garages, hotels, restaurants and department stores; and of course, what happens if your card is lost or stolen. A credit card thief may be sitting on a potential goldmine particularly if there is a delay in reporting the loss of the card.
However, if used wisely, a credit card can cost nothing, or at least help to tide you over a period of financial difficulty.

【推荐2】When people get old and have difficulty working fulltime, they retire and begin a new, more relaxing lifestyle. But what about old industrial buildings? Can they start a new?
China seems to find a good solution for them. In recent years, many abandoned factories, railway yards, warehouses and mills(磨坊) have been transformed into cultural and tourist sites.
The 798 Art Zone in Beijing is an iconic example. Built in the 1950s as No. 718 Joint Factory, it was gradually abandoned in the 1990s as production slowed down. In 2006, Beijing’s municipal government invested over 120 million yuan and improved its infrastructure (基础设施) condition, turning the factory complex into a cultural and creative industrial base. Now the art zone holds about 200 galleries, art centers as well as fashionable boutiques (精品店), cafes, and restaurants, which also earns it a place on the bucket list of many tourists, noted The Paper.
Jack Liu is a frequent er of the art zone who visit site very weekend. “In the art zone, you can refresh memories of the development of Chinese manufacturing through it sold buildings,” said the 28-year-old to Teens. “However, in art galleries here you will feel pulled into a fashionable, modern world. It’s amazing.”
Industrial heritage sites, which used to be filled with the rumbling of machines, are now precious pages of the book on the industrial culture of China, noted People’s Daily. Since these heritage sites are rich and diverse in content cities in China also spare no effort to explore new ways and models to protect and use them. For example, a beer museum has been setup inside a century-old plant of the Tsingtao Brewery in Qingdao, Shandong province, bringing people closer to the long history of the brewery. Some abandoned plants in Beijing have also been remade for city explorers to take adventures in.
Just as the elderly need our care and love, these industrial heritages are also expected to be injected with vitality (活力) through protection and development. “It is not only a trend of the innovation-driven development of cities, but a necessity for promoting new drivers of development,” noted Peoples’ Daily.

【推荐3】There’s a lot of confusion around exercising and eating. What should you eat before you work out? What about after? How long should you wait to eat? How will all of this benefit your goal of losing more fat? Scientists have now answered one important question.
In a new study researchers had a group of overweight males walk for one hour on an empty stomach, and then had them walk again for 2 hours on another day after eating a good breakfast. The researchers collected their blood samples after eating or fasting (禁食) as well as after exercising. They also took fat samples directly before and directly following an hour of walking.
The results showed differences in gene expression of the fat tissue in the two tests. The two genes they looked at, PDK4 and HSL, increased as a result of the volunteers fasting and exercising, and decreased when they ate before exercising. The researchers believe that the rise in PDK4 likely shows that stored fat was used to fuel metabolism (新陈代谢) during exercise,and that HSL increased when the fat tissue used stored energy to benefit an increase in exercise.
According to Dylan Thompson, an author of the study, the results support the viewpoint that “fat tissue often faces competing challenges”. “For example,” he says, “after eating the body is busy responding to the meal, and a short period of exercise at this time will not cause the same beneficial changes in fat tissue.”
How long do you have to decline food to meet their definition of “fasting”? Thompson says, “The best advice would be to make sure that your last meal was 4 hours before exercise to get the effect that we reported.”

A STRAIGHTFORWARD INCOME? INVEST IN HIGHWAYS. Discover why now may be a good time for municipal bonds In today’s particularly unstable economy, aiming for secure sources of income is more relevant than ever. Tax-free municipal bonds (市政债券) (often issued to fund major infrastructure projects for example highways) offer two significant benefits. They can provide historically low risk, and income from bonds is federally (联邦地) tax free. With municipal bonds, investors are paid back the full-face value of their investment at maturity (or earlier, if called) unless the bond defaults, or fails to pay. This historically low risk is essential for many investors, particularly those in, or close to, retirement. In August of 2019, Moody’s Investor’s Service found that rated investment-grade municipal bonds had an average increasing 10-year default rate of just 0.10% between 1970 and 2018. Therefore, they can be an important part of your investment. Income from municipal bonds is not subject to federal income tax and, depending on where you live, may also be free from state and local taxes. Tax-free income can be a big attraction for many investors. Since 1990, Hennion & Walsh has specialized in investment-grade, tax-free municipal bonds.

【推荐2】For the past three decades, companies and consumers have benefited from cross—border connections that have helped to maintain a steady supply of electronics, clothes, toys and other goods so abundant that it has managed to keep prices low across the board.
However, as the pandemic and the Russia — Ukraine conflict continue to weigh on trade and business ties, that period of plenty appears to be undergoing a partial reversal. Companies are rethinking where to source their products and are stockpiling inventory (库存), even at the potential cost of lowering their efficiency and increasing their operation expense. If the situation lasts for very long,
American economists are debating whether recent supply chain troubles and geopolitical conflicts will result in a shake-up of global production, in which factories that had previously been sent offshore or areas with fewer tax regulations, move back to the United States or into other more stable countries. If this happens, a decades-long decline in the prices of many goods could come to an end. We may even witness a slide backwards, meaning a potential boost in prices and overall inflation as a result.
The period of global integration before the pandemic made many of the things Americans buy cheaper. Computers and other forms of technology made factories more efficient, and they rolled out sneakers, kitchen tables, and electronics at a pace unmatched in history. Companies slashed their production costs by moving factories offshore, where wages were lower. The adoption of steel shipping containers and ever larger cargo ships allowed products to be transported from Bangladesh and China to Seattle and Tupelo and everywhere in between at astonishingly low prices.
Those changes, however, had consequences for American factory workers, who saw many jobs disappear. Katherine Tai, the U. S. trade representative, said that, while American consumers have enjoyed the “luxury” of low prices for imported goods for a long time now, the system upon which it was built has always been a very “fragile” one. Americans are not just consumers, but also workers who have to compete in a global marketplace for talent where globalization “has damaged opportunities and wages for average American workers”.
“Some returning is occurring — let’s make no mistake about that.” Ngozi Okonjo-Iweala., the Director-General of the World Trade Organization, said in an interview. But the data shows that most businesses are reducing their risk by building up their inventories and finding additional suppliers in low-cost countries, such as Vietnam and Mexico. This process could end up helping more deeply integtate poorer countries in Africa and other parts of the world into the global value chains, said Dr. Okonjo-Iweala.
The intertwined trajectory (轨迹) of globalization, low prices, and inflation on the whole will be closely watched by economists over the years to come. “It would certainly be a different world.” Jerome H. Powel, the chair of the Federal Reserve, said when asked about a possible move away from globalization. “It’s not obvious how dramatically conditions will change,” he said. “But it’s clear that it’s slowed down.”

【推荐3】On Friday, Silicon Valley Bank (SVB) collapsed and was taken over by federal regulators, marking one of the largest bank failures since the 2008 Global Financial Crisis. California’s banking regulators shut down SVB and effectively gives control of the bank to the FDIC, which created a new entity(实体) to oversee it. With a 40-year history, SVB served many companies, and it played an important role in the technology industry, successfully competing with bigger-name banks.
SVB’s business boomed as tech companies did well during the Covid-19. However, the technology industry recently faced difficulties, and many clients withdrew money. To fulfill these withdrawals, SVB sold part of its bond holdings(持有债券) at a $1.8 billion loss. The Federal Reserve’s(美联储) sharp rise in interest rate also affected bonds and stocks. Then SVB decided it wanted to reduce its bond portfolio(债券投资组合) to avoid further losses.
But that announcement spooked the bank’s clients, who got worried and then proceeded to withdraw even more money from the bank—a textbook definition of a bank run. The bank’s stock price(股价) fell by 60% on Thursday, and as its share price continued to sink overnight. Trading was halted, and the FDIC took over SVB.
While concerns emerged about the banking sector, shares of major banks like J. P. Morgan, Wells Fargo, and Bank of America dropped by around 5%. Investors worried that other banks, particularly smaller ones, might experience similar withdrawals. However, by Friday, fears regarding the broader banking sector had eased. Experts argued that SVB’s situation was unusual and should not impact other regional banks.
The FDIC-created entity, Deposit Insurance National Bank of Santa Clara, will oversee SVB. Insured deposits(存款), typically up to $250,000, will be accessible by Monday. Uninsured deposits face uncertainty, with the FDIC offering an “advance dividend(提前股息)” and “certificates” accounting for the uninsured funds. The regulator has not clarified what this means for uninsured depositors. Investors will continue monitoring any potential impact on other banks.
