Bloomberg: US-China Trade War: The Technologies Hit The Hardest [feedly]

US-China Trade War: The Technologies Hit The Hardest
https://www.bloomberg.com/graphics/2019-trade-war-us-china-technology/


A trade war between the world's two largest economies erupted this year, and technology is at the center of the skirmish. President Donald Trump blocked networking giant Huawei Technologies Co. from buying U.S. components, and put tariffs on many Chinese products. China responded by threatening to blacklist U.S. companies. The rising tension is testing a complex relationship, especially in tech where the U.S. and China are tightly intertwined through global supply chains and software that can zip across borders with the tap of a computer key. So which country has the most to lose? Who needs the other nation more?

U.S. companies Intel Corp. and Nvidia Corp. dominate the market for processors, the key component of all laptops, desktop and server computers. The only viable alternative is another American firm: Advanced Micro Devices Inc.

The processors are manufactured mostly in Taiwan. Intel has one plant in China, but it makes memory chips—a commodity component. Huawei unveiled its first home-grown server chip this year, based on designs from ARM Holdings Inc., which is headquartered in the U.K. ARM has operations in the U.S., too, and the company recently said its products fall under the U.S. export controls. Without the latest ARM designs, Huawei may struggle to make its own chips.

In smartphones, Huawei is more independent, supplying at least two-thirds of its own processors and modems, according to analysts' estimates.

Huawei, a top networking gear provider, has been a huge buyer of these components. If the Chinese company wanted to develop its own switch chips, it would still need other U.S. technology. Synopsys Inc. and Cadence Design Systems Inc. are the main suppliers of software that's used to design chips—and they both cut Huawei off recently.

China is betting heavily on AI. Money is pouring in from China's investors, big internet companies and its government, driven by a belief that the technology can remake entire sectors of the economy, as well as national security. A similar effort is underway in the U.S., but in this new global arms race, China has three advantages: A vast pool of engineers to write the software, a massive base of 751 million internet users to test it on, and most importantly staunch government support that includes handing over gobs of citizens' data—something that makes Western officials squirm.

China And Market Socialism [feedly]

China And Market Socialism
http://www.humaniteinenglish.com/spip.php?article3302


CHINA AND MARKET SOCIALISM
ESSAY

Monday, June 17, 2019

Rémy Herrera
The "Chinese Model" and us Tony Andréani L'Harmattan, 208 pages, 21.50 euros.
In a book that goes off the beaten track, Tony Andréani analyses the current situation.

To those who claim that China has converted to capitalism, Tony Andréani replies in this book that Chinese successes are due to "a draft of market socialism". According to precise criteria defining such socialism (prevalence of collective choices, planning, etc.), he shows that China meets them. The term "draft" means that, for some of these criteria (e.g. social security or labour law), however, it has a long way to go. It would only be at a "primary phase of socialism", as the Chinese themselves call it - which is already much more than "left-wing Keynesianism". The author thus rejects the traditional expression of "state capitalism", in particular because state enterprises are not there to pay dividends to the state owner or to value its securities, are otherwise managed through meaningful management participation of their employees and occupy all key sectors of the economy by "serving as the armed arm of the state" for the achievement of its objectives.

He argues that in China the state controls capitalist oligopolies in many ways (control of capital, credit by large public banks, joint ventures, presence in the capital and board of directors of large private companies) and that it stimulates effective demand through public investment, which is the driving force behind each stimulus. Tony Andréani insists that state-owned enterprises are not focused on capitalist profitability. According to him, it is the low prices of the various inputs they provide to other companies in the domestic economy that make Chinese exports more successful commercially than low wages. Moreover, a significant part of the Chinese economy is not strictly speaking capitalist (number of small businesses, crafts, so-called "collective" economy) and cannot therefore practice capitalist prices. In addition, the Chinese government is trying to control the capital markets, particularly the financial markets, by continuing to favour (and regulate) the credit market and banking intermediation. Exciting and original developments are devoted to the political and social system in this courageous, relevant, informed and useful book.

Tim Taylor: Is Hydrogen the Storage and Carrying Technology for Carbon-Free Energy? [feedly]

Is Hydrogen the Storage and Carrying Technology for Carbon-Free Energy?
http://conversableeconomist.blogspot.com/2019/06/is-hydrogen-storage-and-carrying.html

Fossil fuels store energy until they are burned. Solar and wind power generate electricity, but don't store it. As a result, they are intermittent sources of electricity, requiring back-up generation capacity that is typically still supplied by fossil fuel. Could hydrogen become a way of storing energy from renewable power sources? The International Energy Agency, in a report on The Future of Hydrogen, describes what would be needed to make this happen (June 14, 2019, accessing report requires free registration). 

At present, hydrogen is mostly produced from fossil fuels, and used only in fairly narrow applications. The report notes: 
Hydrogen is almost entirely supplied from natural gas and coal today. Hydrogen is
already with us at industrial scale all around the world, but its production is responsible
for annual CO2 emissions equivalent to those of Indonesia and the United Kingdom
combined. Harnessing this existing scale on the way to a clean energy future requires
both the capture of CO2 from hydrogen production from fossil fuels and greater supplies
of hydrogen from clean electricity. ... Today, hydrogen is used mostly in oil refining and
for the production of fertilisers. For it to make a significant contribution to clean energy
transitions, it also needs to be adopted in sectors where it is almost completely absent at the moment, such as transport, buildings and power generation.
So making the shift to a more use of hydrogen will require a lot of change. The overall vision would be that some of the sources of renewable energy like solar, wind, and hydro could become hydrogen farms, separating hydrogen from water. Instead of building electrical power lines from these facilities, there would need to be a system for storing and transporting the hydrogen they produce, similar to all the ways that natural gas (and liquified natural gas) are transported today. There would need to be early adopters of hydrogen fuel cell vehicles, perhaps focusing first on organizations with fleets of vehicles like trucks or buses. Building would need to be designed or retrofitted to use hydrogen as a source for heating, cooling, and electricity.

These changes are substantial!  As the report notes, there have been a few previous moments when hydrogen was widely discussed as a method of storing and carrying energy: the 1970s, the 1990s, and the early 2000s. When oil prices declined after about 2011, government R&D spending on hydrogen also declined.
However, if technological progress can continue to drive down the costs of hydrogen, the potential benefits are also substantial, because hydrogen technology offers a way in which renewable power that now generates electricity could instead be used to address sectors of the economy where electricity has proven to have practical drawbacks. The report notes:
The increased focus on reducing [greenhouse gas] emissions to near zero by mid-century has brought into sharp relief the challenge of tackling hard-to-abate emissions sources. These emissions are in sectors and applications for which electricity is not currently the form of energy at the point of end use, and for which direct electricity-based solutions come with high costs or technical drawbacks. Four-fifths of total final energy demand by end users today is for carbon-containing fuels, not electricity. In addition, much of the raw material for chemicals and other products contains carbon today and generate CO2 emissions during their processing. Hard-to-abate emissions sources include aviation, shipping, iron and steel production, chemicals manufacture, high-temperature industrial heat, long-distance and long-haul road transport and, especially in dense urban environments or off-grid, heat for buildings. Rapid technological transformations in these sectors have made limited progress in the face of the costs of low-carbon options, their infrastructure needs, the challenges they pose to established supply chains, and ingrained habits. ... As a low-carbon chemical energy carrier, hydrogen is a leading option for reducing these hard-to-abate emissions because it can be stored, combusted and combined in chemical reactions in ways that  are similar to natural gas, oil and coal.

The Economic Value of Household Production: 1965-2017
http://conversableeconomist.blogspot.com/2019/06/the-economic-value-of-household.html

Gross domestic product is not the total amount of output produced; instead, it is a a measure of what is bought and sold in markets. Pretty much every intro class in economics will point out to students that when I clean my own house, cook my own meals, look after my children, or or mow my lawn, that "household production" doesn't show up in GDP. But if I hire someone to do household production tasks, then that output gets counted as part of GDP.

For a number of situations where the limitations of GDP are obvious, the US Bureau of Economic Analysis publishes "satellite" accounts, where it calculates what a different and broader measure of economic output would look like. In this spirit, Danit Kanal and Joseph Ted Kornegay have written "Accounting for Household Production in the National Accounts: An Update, 1965–2017," in the June 2019 Survey of Current Business.

The overall approach is to look at data on time use in household production, estimate the cost of hiring that time in the market, and then add this output to the standard conventional measure of GDP. They write:
The largest impact when including household production in GDP stems from the inclusion of nonmarket services. Nonmarket services measure the value of time spent on home production tasks. ... To compute household production, we first aggregated household production hours across seven categories: housework, cooking, odd jobs, gardening, shopping, child care, and domestic travel. The value of nonmarket services is the product of the wage rate of general-purpose domestic workers and the number of hours worked. This method assumes a market-cost approach to valuing nonmarket household services. ... BEA's current GDP measure treats consumer purchases of durable goods as consumption. In contrast, this satellite account treats such purchases as investment and adds the services of consumer durables to personal consumption expenditures. 
Some interesting fact patterns emerge from thinking about economic output in this way:

When this calculation is carried out for 1965, the revised GDP with household production included is 37% higher than the conventional measure. For 2017, the revised GDP with household production included is 23% higher.

Thus, if you are someone who sometimes uses per capita GDP as a quick-and-dirty measure for social well-being (a sin of which I've been guilty now and again), taking household production into account shows that the US standard of living is higher than the conventional measurement.

Why does adding a value for household production have a smaller effect now than a half-century ago? "Household production has declined in significance over time as more women engage in market work." In particular, the number of hours spent in household production by nonemployed women has declined substantially.

The growth rate for total economic output is slower. Measured in nominal dollars, the growth rate of traditional GDP is 6.5% per year from 1965 to 2017, while the annual nominal growth rate of output falls to 6.3% per year with household production in included. In effect, the declining hours spent on household production mean that the relative size for this part of the economy is shrinking.

As usual with economic statistics, any one number is going to have serious limitations, and so looking at a variety of interrelated measures will provide a more in-depth picture. Here, the authors are just presenting fact patterns, not hypothesizing about underlying causes. But presumably there are a variety of changes behind these patterns, like fewer children in the average household, the spread of household technologies like the dishwasher and the microwave, and household which choose to purchase some services (meals eaten out, house-cleaning, yard work) rather than producing it themselves.
