Lùm xùm về thuế ở Tây Ban Nha

phải lên tận tòa án tối cao để phân xử người mua nhà hay ngân hàng nộp thuế thế chấp bất động sản,

trong khi bài học vỡ lòng econ 101 là ai nộp thuế thì cũng ko thay đổi người thực sự chịu thuế (không bị quyết định bởi luật quốc hội mà là luật cung cầu :)
Spain is currently embroiled (lôi kéo (ai) vào một cuộc xung đột, làm rối tung lên, làm rắc rối (vấn đề)) in tremendous (ghê gớm, khủng khiếp, dữ dội) debate (cuộc tranh luận) over who should pay the AJD tax, a tax on the creation of a mortgage (thế chấp mua nhà). Should the buyers (consumers) or the sellers of the mortgage (the banks) pay the tax? The Supreme Court, the President, and the legislature have all stepped in.

...What's amazing is that the Spanish uproar is over a decision that Econ 101 says does not make a whit's worth of difference to anything of importance. Whether the buyers send the check to the government or the sellers does not change the true incidence of the tax. As Tyler and I say in Modern Principles, "Who pays the tax does not depend on the laws of Congress but on the laws of supply and demand." The tax simply drives a wedge (cái nêm (để bổ gỗ, bửa đá, mở rộng một lỗ hổng hoặc giữ cho hai vật tách ra) between what the buyers pay and what the seller receives. Since sellers typically post prices, when the sellers must send the check the posted price will include the tax but the price the sellers receive will be the posted price minus the tax. If buyers must send the check to the government the posted price will not include the tax but the buyers will have to pay the posted price plus the tax. Either way, the seller, buyer, and government all end up net the same amount. It's little different than debating whether the right or left hand must pay the tax. See Tyler in the video below for the diagram and further details.

Thus, the whole Spanish imbroglio (tình trạng hỗn độn (về chính trị...), sự hiểu lầm rắc rối, tình trạng rắc rối phức tạp (trong một vở kịch), đống lộn xộn) has been caused by a failure to understand Econ 101.

Màn thuyết trình trước shark đầy thuyết phục

ngâm mình trong nước lạnh để trình bày về dự án khởi nghiệp...

Polar Bear Pitching allows start-up firms to put forward their projects to investors for as long as they can stand in the freezing temperatures.

The final of the Dragon’s Den-style competition will see a dozen companies put their plans under the noses of investors.

The winner of the two-day contest — which takes place in frozen sea near Oulu on February 6 and 7 — will receive €10,000.

Start-ups who have secured funding say standing in such cold water helps convince investors they are serious.

Valentine’s Day and Understanding the Price System

A Price Is a Signal Wrapped Up in an Incentive

...exploring the mystery and marvel of prices. We take a look at how oil prices signal the scarcity of oil and the value of its alternative uses. Following up on our previous video, “I, Rose,” we show how the price system allows for people with dispersed knowledge and information about rose production to coordinate global economic activity. This global production of roses reveals how the price system is emergent, and not the product of human design.

Vai trò của tôn giáo trong đời sống xã hội

trước đây, trong một thời gian dài, chúng ta đã coi tôn giáo như là "tàn dư" của xã hội cũ, là kết quả sai lầm trong nhận thức của con người. Tôn giáo bị xem như cái đối lập với chủ nghĩa xã hội, với khoa học, kỹ thuật hiện đại và cần phải loại bỏ.

Religion and faith are an integral part of people’s lives worldwide. But in many countries the number of people who believe in God is in decline. We examine the changing role of religion around the world...

Sự thật về năng lượng gió có thể bạn chưa biết

giấc mơ năng lượng miễn phí cho mọi nhà sắp thành hiện thực ở Ấn Độ,
Low-Cost Wind Turbine to Power an Entire House for a Lifetime Starts Selling in India

these words “for the cost of an iPhone, you can now buy a wind turbine that can power an entire house for a lifetime” have been trending

India is the world’s sixth largest energy consumer, accounting for 3.4% of total global energy consumption.

to help rural dwellers, a startup in the country has invented a cheap wind turbine that could power an entire house for a lifetime. The young company called Avant Garde is owned by two young siblings, Arun and Anoop George. They are based in the Indian southern state of Kerala. Their wind turbine can generate 3-5 kW of electricity daily.

Without erecting electric posts and electric lines that require huge investments that could cost millions of dollars, Avant Garde was able to generate clean and renewable electricity for the people in the area through their wind turbine.

Kẻ phá bĩnh thị trường ôtô

Ride-hailing apps such as Uber, Ola and Lyft are not only challenging taxi drivers around the world, they are also disrupting the car industry as a whole as people prefer to hail a ride than buy their own set of wheels.

Tái khởi động vĩ đại

Economic progress is not continual and inevitable. It can be disrupted with short downturns and, as we’ve seen in this series, periods of stasis. If we continue on this trajectory, there is the possibility of a “great reset” and there are some strong indicators that it’s already underway.

Let’s think of these indicators as “canaries in the coal mine.” Miners used to take canaries with them to provide an alarm when levels of toxic gases were too high. The birds were much more susceptible to the gases and would show signs of distress – or even die – before the miners were in grave danger.

During the Great Recession, subprime borrowers acted as the canaries. Poor credit and lower incomes made them the most susceptible to trouble in the larger financial system, and they showed signs of distress first – missed payments and foreclosures. The whole system was cracking up, but we saw it here first.

Where are the possible canaries today? The Ferguson and Baltimore riots suggest stress on America’s race relations and inner cities. Millions of men of prime working age are missing from the U.S. labor force. And what about the 2016 election? Trump’s political rise indicated serious discontent among millions of American voters, but elite political commentators, up until the very end, did not see Donald Trump becoming president.

If we look at these events as connecting the dots between stresses on the American economy, we can see some commonalities – namely, a loss of trust. People are losing trust in American institutions. Wage growth is sluggish, people are experiencing more socioeconomic segregation, and politics have us increasingly divided.

What happens if the U.S. faces a crisis? Can we respond to huge job loss from unforeseen automation? What about a foreign policy crisis, or infrastructure collapse? The American economy, with its current loss of dynamism and innovation, would have trouble responding to any sudden crisis. The federal government, with so much revenue already tied-up, would as well.

If we stay on the course of complacency, a great reset is very possible and it won’t be pleasant. But it’s not all doom and gloom. In the longer run, such a crisis could reinvigorate the American pioneer spirit, putting the U.S. back on a path of economic dynamism and growth.

Người mất tích ở Mỹ

We’re going to paint a not-so-pretty picture of the current U.S. labor force: Millions of working age (25-54) American men do not have jobs and, because they are not actively seeking work, do not count towards our primary unemployment statistic. Many of these men are living at home with their parents. They are not attending school. They are not stay-at-home dads. In fact, much of their time is going towards leisure activities such as watching television and playing video games. Almost half are on painkillers.

To be clear, this picture does not apply to every working age male without current employment, but it is accurate for a disturbingly high percentage.

If we look specifically at men without a college degree and job who are in their twenties, we find that in 2000, less than 10% had not worked at all in the past year. 15 years later, that number had more than doubled to 22%.

As of 2015, an estimated 5.5 million prime-age men (25-54) were neither working nor enrolled in school – the equivalent of the combined populations of Dallas, Philadelphia, and Chicago. It’s a worrisome trend for the economy and there’s no clear-cut answer as to why it’s happening.

Up next, we’ll discuss the possible “great reset” on the United States’ economic horizon and whether the missing men phenomenon could be a driving force.

Sự ngưng trệ của nước Mỹ

Disruption. This is the big buzzword when it comes to startups and Silicon Valley. Many of the top tech businesses today have caused major disruptions in their industries – from Uber, to Airbnb, and even Facebook, these tech giants are changing the game. However, if we peer outside of this small window, the narrative of fast-paced innovation and a rapid rise in startups falters.

In fact, the rate of startups forming has trended lower and lower beginning in the 1980s. Younger firms are also less likely to become successes than they have been in the past. Outside the sphere of the few highly-visible companies that have made strides in improving our standard of living, the U.S. economy is stagnating.

Lots of older firms with a lower rate of new ones starting up means fewer jobs are being created and destroyed. Established firms are enjoying a larger share of the market. Giants are sitting on their piles of cash, and sometimes acquiring other large firms, instead of investing in new ideas. This lack of dynamism shows in productivity growth, which has mostly been on the decline since 1973.

For employment, fewer young firms means less job mobility. People are, again contrary to the usual narrative, staying in the same jobs for longer than ever before. And that slowdown in productivity growth shows up in places like real wages. In fact, if the U.S. had continued at pre-1973 productivity growth, the median American household income would be about $30,000 higher.

Finally, U.S. federal revenue is increasingly on auto pilot. In 1962, roughly 65% of federal revenue fell under “fiscal discretion,” allowing for new allocations each year. Today, the vast majority of federal revenue is wrapped up in predetermined spending like debt, Medicaid, social security, and Medicare. By 2022, less than 10% of U.S. federal revenue might be considered discretionary.

All of these factors lead to a more “boxed in,” less flexible, less dynamic economy. This is not an advantageous position – living standards are increasing more slowly, sowing seeds of discontent, and it’s difficult for a federal government with little discretionary spending to respond to a crisis.

In upcoming videos, we’ll look at some of the discontent currently happening in the U.S. and what might happen if a crisis were to occur and our lives were to be truly disrupted during this time of economic stagnation.

Kỷ nguyên mới của sự phân biệt

Do you live in a “bubble?” There’s a good chance that the answer is, at least in part, a resounding “Yes.”

In our algorithm-driven world, digital servants cater to our individual preferences like never before. This has caused many improvements to our daily lives. For example, instead of gathering the kids together for a frustrating Blockbuster trip to pick out a VHS for family movie night, you can simply scroll through kid-friendly titles on Netflix that have been narrowed down based on your family’s previous viewing history. Not so bad.

But this algorithmic matching isn’t limited to entertainment choices. We’re also getting matched to spouses of a similar education level and earning potential. More productive workers are able to get easily matched to more productive firms. On the individual level, this is all very good. Our digital servants are helping us find better matches and improving our lives.

What about at the macro level? All of this matching can also produce more segregation – but on a much broader level than just racial segregation. People with similar income and education levels, and who do similar types of work, are more likely to cluster into their own little bubbles. This matching has consequences, and they’re not all virtual.

Power couples and highly productive workers are concentrating in metropolises like New York City and San Francisco. With many high earners, lots of housing demand, and strict building codes, rents in these types of cities are skyrocketing. People with lower incomes simply can no longer afford the cost of living, so they leave. New people with lower incomes also aren’t coming in, so we end up with a type of self-reinforcing segregation.

If you think back to the 2016 U.S. election, you’ll remember that most political commentators, who tend to reside in trendy large cities, were completely shocked by the rise of Donald Trump. What part did our new segregation play in their inability to understand what was happening in middle America?

In terms of racial segregation, there are worrying trends. The variety and level of racism of we’ve seen in the past may be on the decline, but the data show less residential racial mixing among whites and minorities.

Why does this matter? For a dynamic economy, mixing a wide variety of people in everyday life is crucial for the development of ideas and upward mobility. If matching is preventing mixing, we have to start making intentional changes to improve socio-economic integration and bring dynamism back into the American economy.
