A collapse of global tax talks could cost $100 billion, OECD says

PARIS (Reuters) - The global economy could shed more than 1% of output if international talks to rewrite cross-border tax rules break down and trigger a trade war, the OECD said on Monday, after countries agreed to keep up negotiating to mid-2021.

Nearly 140 countries agreed on Friday to extend talks, after the pandemic outbreak and U.S. hesitation before the presidential election squashed hopes of reaching a deal this year.

Public pressure is growing on big, profitable multinationals to pay their share under international tax rules after the COVID-19 pandemic strained national budgets, the countries said in an agreed statement.The aim is to update international tax rules for the age of digital commerce, in particular to discourage big Internet companies like Google , Facebook and Amazon from booking profits in low-tax countries like Ireland, regardless where their customers are.


In the absence of a new international rulebook, a growing number of governments are planning their own digital services taxes, which has prompted threats of trade retaliation from the Trump administration.

"The alternative to finding an agreement would be a trade war ... The last thing you want at this time with COVID-19 is to have to deal with further trade tensions," OECD Secretary General Angel Gurria told journalists.

In such a worst-case scenario, trade disputes could knock global GDP back by more than 1%, the OECD, which has been steering the global tax talks, estimated in an impact assessment.

Conversely, new rules for digital taxation and a proposed global minimum tax would increase global corporate income tax worldwide by 1.9% to 3.2%, or about $50 billion to $80 billion per year.

That could reach $100 billion when including an existing U.S. minimum tax on overseas profits, amounting to 4% of global corporate income tax, the OECD said. Meanwhile, any drag on global growth would be no more than 0.1% in the long term.


At the same time, new digital taxation rules would shift the right to tax $100 billion in corporate profits to big consumer- market countries, largely at the expense of low-tax investment hubs where such profits currently get booked.

While countries agreed on OECD blueprints for a future deal, the key remaining issue to be solved was the scope of businesses to be covered, which would then make it easier to agree the technical parameters, OECD head of tax Pascal Saint-Amans said.

The Trump administration had insisted on an opt-in option for U.S. companies, which has been broadly rejected by other countries in the talks.

Nonetheless, regardless of the results of the U.S. presidential election next month, there was bipartisan support in Washington to move forward, Gurria said.

Minneapolis Federal Reserve President Neel Kashkari told CBS "Face the Nation" on Sunday the recovery from the pandemic is stalling and called for more for fiscal aid.

 

He said: "If 11 million Americans can't pay their bills, can't put food on the table, can't make their credit card payments, their car payments, that has spillover effects to other sectors of the economy." 

 

Democrats rejected an increased offer of $1.8 trillion in fiscal aid by the White House over the weekend.


Minneapolis Federal Reserve President Neel Kashkari told CBS's "Face the Nation" on Sunday the strong recovery seen in the US economy in recent months has "flattened" out and called on lawmakers in Washington to reach an agreement on another round fiscal aid.

"The recovery, the strong recovery that we saw in June and July, has really flattened out. The virus is climbing now again around the country, especially here in my region, in Minnesota, the Dakotas, Wisconsin," Kashkari said. "And so you're seeing consumers pull back and not want to go out, and not want to take that risk again. And so, unfortunately, we still have a long way to go in this pandemic, and that means we need continued assistance."

He said job losses and bankruptcies in the travel and tourism industries, front-line service industries and restaurants will continue to spiral and "bleed on" if lawmakers don't reach a compromise. Democrats and Republicans have been caught in a stalemate since July over the size and scope of a new set of economic stimulus measures.

Southwest pilots' union bristles at 10% pay cut proposal
 

Southwest Airlines pilots' union took issue at a company proposal to cut pay rates by 10%.

Southwest has said it won't furlough or cut pay rates this year but is seeking concessions for next year.

The carrier has never furloughed an employee in its nearly 50 years of flying

Southwest Airlines pilots' union is pushing back on a company proposal to cut pay by 10% to avoid furloughs through the end of next year, the latest wrinkle in the Dallas-based carrier's efforts to cut costs in the pandemic.

Southwest is trying to preserve its record of never having furloughed workers in its nearly 50 years of flying, but its CEO Gary Kelly warned earlier this month that it would seek concessions from the labor unions that make up the bulk of its workforce.

"Our goal is to protect every pilot job so we can be prepared to take advantage of revenue opportunities when customer demand returns," Southwest said in an emailed statement. "Until then, we must also begin to restore our balance sheet by more closely aligning our loss in revenue with lower costs."

All U.S. airlines are struggling with a plunge in revenue from the sharp drop in travel demand because of the virus. In the first 10 days of the month, the Transportation Security Administration screened an average of 804,302 people a day, down nearly 66% from the same period a year ago.

On Friday, Southwest proposed the 10% pay rate cut to its roughly 9,000 pilots. The union, the Southwest Airlines Pilots Association took issue with the across-the-board reduction and force majeure clauses, which it feared the airline could lean on to furlough pilots anyway.

"This addition would not protect us from furloughs or ensure us that our hourly trip rates would snap back after the term of any agreement," the union said in a memo to members.

The union pointed to other options like voluntary time off at reduced pay and early retirement packages.

"We have a revenue and short-term cash problem that cannot be fixed by concessions alone," the union said in a memo on Friday. Its president Jon Weaks, told CNBC the company's proposal is "dead on arrival" but that the union is open to further talks on cost-cutting measures.

The dispute comes as competitors American Airlines and United Airlines earlier this month began cutting more than 30,000 jobs after the terms of billions in federal aid expired. Southwest doesn't plan to furlough workers this year but earlier this month said it would seek concessions from unions for a committment to keep jobs through 2021.

United Airlines pilots agreed to reduce minimum hours in order to prevent close to 3,000 furloughs planned this year.

Big businesses are protecting exec pay by rewriting bonus plans and changing performance targets during COVID-19, a report has found

Big businesses are protecting executives' pay by rewriting bonus plans and changing performance targets, a report has found.

 

Companies have added non-financial targets and written off worst-performing months, Semler Brossy Consulting Group said.

 

For example, Olive Garden parent company Darden Restaurants modified its bonus plans so that lower sales at the peak of lockdown won't count against execs, the group said.

 

Many companies have cut employee pay and laid off staff, and adjustments that appear to protect executive pay "are likely to get outsized attention," Semler Brossy warned.

Big businesses are protecting their executives' pay during the pandemic by rewriting bonus plans and changing performance targets, a report has found.

Some companies have simply written off the worst-performing months, while others have added non-financial metrics to bonus-linked targets, according to Semler Brossy Consulting Group's investigation of 29 large US firms, reported by the Financial Times.

Ten companies modified the period that performance is measured over, typically to cover just a partial year. This means that executives' annual performance won't be dragged down by poor performance during the peaks of the pandemic.

Many companies have cut staff numbers or employee pay, and adjustments that appear to protect executive pay "are likely to get outsized attention," the group warned.


Olive Garden parent company Darden Restaurants modified its bonus plans so that lower sales at the peak of lockdown won't count against exec bonuses, Semler Brossy said, per an SEC filing.

Its 2021 bonus plan will use non-financial metrics during the first half of the fiscal year alongside financial results from the second half, and the board will use its discretion to award bonuses, the FT reported.

Gene Lee, Darden's CEO, was among a number of executives who pledged to take pay cuts in the early days of the pandemic, an apparent act of solidarity with struggling workers.

Lee said he would forgo his $1 million base salary in early April. As of early June, SEC filings showed his salary had already been reinstated.


Casino operator Wynn Resorts, which runs the world's largest five-star resort, modified bonus goals for some executives for the second half of 2020 to encourage saving cash, rather than generating earnings, with "significantly reduced target incentive levels" for the year, the Semler Brossy report found, per an SEC filing.

Both Darden and Wynn Resorts did not immediately respond to a Business Insider request for comment. Representatives from Wynn Resorts and Darden declined to comment to the FT.

The report found that, among the 29 large companies, new performance metrics included cash flow, strategic and operational health measures, and earnings before interest, taxes, depreciation, and amortization.

Semler Brossy argued that, while incentives are important to keep executives motivated, any rewards "must be proportionate and aligned with the broader impact of COVID-19 on shareholders, on employees, and on society at large."

Boards should acknowledge other stakeholders when planning their executive bonus programs, Semler Brossy said.

"The media are actively looking for stories of corporate greed in a pandemic, and even innocuous seeming changes, such as shifting some performance-based awards to time-based vesting, have resulted in negative stories," the company added.



Denver shooting suspect not a licensed security guard, city says

SECURITY GUARD IS WHITE WHICH IS WHY HE IS ALIVE

Matthew Dolloff, 30, was taken into custody Saturday after allegedly shooting and killing a man in the midst of dueling rallies between left- and right-wing protesters. Local NBC News affiliate KUSA-TV said the person taken into custody for the shooting was a private security guard hired by the station.

"There is no record for an active licensed security guard now or ever for an individual named Matthew Doloff or Dolloff. If he was operating as a security guard, he was in violation of the law," The Denver Department of Excise and Licenses told CBS Denver's Andrea Flores.

"A security guard operating without a license could be fined up to $999 dollars and face up to a year in jail," the department told CBS News. "The company he works for is also legally responsible for making sure all their security guard employees have a license and could face administrative action against their required security guard employer license if they have security guards working without a license."

"Security guards are prohibited from carrying or using a firearm without getting an armed firearm endorsement for their license," the department added. "All security guards in Denver are required to get a federal background check before they receive their license."

Security guards operating in Denver are also supposed to be in uniform, which Dolloff does not appear to be wearing in videos of the shooting posted to social media. The videos appear to show the victim spraying mace at Dolloff right before the shooting.

KUSA-TV said it hired Dolloff through the Pinkerton security firm, according to The Associated Press. AP also reports Dolloff's name does not appear in the city's database of licensed security guards. Pinkerton did not respond the AP's request for comment.

Dolloff is currently being held on first degree murder charges without bail, CBS Denver reports. Police have not identified the man who was killed.
Mallinckrodt files for bankruptcy protection amid U.S. opioid litigation

(Reuters) - Mallinckrodt Plc filed for bankruptcy protection on Monday, saddled with lawsuits alleging it fueled the U.S. opioid epidemic and after it lost a court battle to avoid paying higher rebates to state Medicaid programs for its top-selling drug.

The company listed both assets and liabilities in the range of $1 billion to $10 billion in a filing with the U.S. Bankruptcy Court for the District Of Delaware.

More than 3,000 lawsuits have been filed accusing drug manufacturers of engaging in deceptive marketing that promoted the use of addictive painkillers, fueling an epidemic that since 1999 has resulted in more than 450,000 overdose deaths.

The company had in February said it planned to have its generic drug business file for bankruptcy as part of a tentative $1.6 billion opioid settlement to resolve claims by state attorneys general and U.S. cities and counties.

It further warned on Aug. 4 the parent company and other units may also seek bankruptcy protection after a judge allowed the federal government to force it to pay higher rebates to state Medicaid programs for its multiple-sclerosis drug H.P. Acthar Gel.

Its per-vial price has risen from about $50 in 2001 to $38,892 in 2019 and it generated 30.1% of the company's net sales last year.

The drugmaker said it will implement a restructuring support agreement that would provide for an amended proposed opioid claims settlement and a financial restructuring.

"The company has agreed to pay $260 million over seven years and reset Acthar Gel's Medicaid rebate calculation as of July 1, 2020, such that state Medicaid programs will receive 100% rebates on Acthar Gel Medicaid sales, based on current Acthar Gel pricing," Mallinckrodt said in a statement.

During the bankruptcy protection, the company said it aims to resolve opioid-related claims and to reduce its debt by about $1.3 billion, while surviving on cash on hand and cash generated from operations.

Simone De Beauvoir’s tragic lesbian love story is finally published

By Agence France-Presse
Simone de Beauvoir STF AFP:File


A tragic love story that Simone de Beauvoir thought “too intimate” to publish during her lifetime will finally see the light of day Wednesday, 34 years after her death.

The great feminist writer recounts her teenage crush for another girl in “Les Inseparables”, the story of a “passionate and tragic friendship between two rebellious young girls.”

But de Beauvoir put the deeply autobiographical novel into a bottom drawer after her partner Jean-Paul Sartre “held his nose” when he read it.

The author of “The Second Sex” wrote how she became “instantly charmed by her new classmate”, Elisabeth “Zaza” Lacoin, who died of encephalitis at the age of 21.

“From the day I met you,” she wrote, “you were everything for me.”

In the novel, the de Beauvoir character does “her all in order to make Andree (a thinly-disguised Zaza) love her back,” said the 2Seas literary agency, who handled the foreign rights for the book.

Described as “moving, gripping coming-of-age novel” that “outlines Simone de Beauvoir’s personal battle against the conventional expectations”, de Beauvoir finished it in 1954, five years after her feminist masterpiece was published.

It’s theme of “the friendship between two young women struggling against conventional ideas of what a woman should be in early 20th-century Paris” echoed “The Second Sex”.

The book’s English publishers, Vintage, said the two girls were expected to be “devout, obedient and obliged from a young age to set aside her own interests and passions” for the men in their lives.

– Unrequited passion –

The writer went on to have several other relationships with women, some of whom were also Sartre’s lovers.

De Beauvoir first evoked her relationship with Zaza in her “Memoirs of a Dutiful Daughter”.

The two were so close during World War I and the 1920s that fellow students and teachers at their school called them the “inseparables”.

Zaza’s relationship with the communist philosopher Maurice Merleau-Ponty, whom she had met through de Beauvoir, scandalised her traditionalist Catholic family.

He appears as a charismatic student in the story, and one of his classmates was none other than Sartre.

The pair quarrelled and then permanently fell out over Soviet communism around the time the novel was written.

By then the object of de Beauvoir’s unrequited love was long dead.

Some have questioned whether Sartre’s rift with Merleau-Ponty may have also played a part in de Beauvoir putting the book to one side.

“It is said that it was Jean-Paul Sartre himself who advised De Beauvoir not to publish the novel, considering it of little interest,” the philosopher Paul B. Preciado wrote in the French daily Liberation.

But Sylvie Le Bon de Beauvoir, the writer’s adopted daughter, thinks that it was she herself who finally renounced it despite several rewrites.

In the preface to the book — which will be published in English next year — she argued that de Beauvoir found “the final fictional transcription of [her love for Zaza] unsatisfying”.

AIR-Act2Act: A dataset for training social robots to interact with the elderly

AIR- Act2Act: A dataset for training social robots to interact with the elderly
Three of the interaction scenarios considered by the researchers, which were recorded using Kinect sensors and included in the AIR-Act2Act dataset. Fig. 2(b) Credit: Ko et al.

To interact with humans and assist them in their day-to-day life, robots should have both verbal and non-verbal communication capabilities. In other words, they should be able to understand both what a user is saying and what their behavior indicates, adapting their speech, behavior and actions accordingly.

To teach social robots to interact with humans, roboticists need to train them on datasets containing human-human verbal and non-verbal interactions. Compiling these datasets can be quite time consuming, hence are currently fairly scarce and are not always suitable for training robots to interact with specific segments of the population, such as children or the elderly.

To facilitate the development of robots that can best assist the elderly, researchers at the Electronics and Telecommunications Research Institute (ETRI) in South Korea recently created AIR-Act2Act, a  that can be used to teach robots non-verbal social behaviors. The new dataset was compiled as part of a broader project called AIR (AI for Robots), aimed at developing robots that can help older adults throughout their daily activities.

"Social robots can be great companions for lonely ," Woo-Ri Ko, one of the researchers who carried out the study, told TechXplore. "To do this, however, robots should be able to understand the behavior of the elderly, infer their intentions, and respond appropriately. Machine learning is one way to implement this intelligence. Since it provides the ability to learn and improve automatically from experience, it can also allow robots to learn social skills by observing natural interactions between humans."

Ko and her colleagues were the first to record interactions between younger and older (i.e., senior) adults with the purpose of training social robots. The dataset they compiled contains over 5000 interactions, each with associated depth maps, body indexes and 3-D skeletal data of the interacting individuals.

"AIR-Act2Act dataset is the only dataset up to date that specifically contains interactions with the elderly," Ko said. "We recruited 100 elderly people and two college students to perform 10 interactions in indoor environments and recorded data during these interactions. We also captured depth maps, body indexes and 3-D skeletal data of participants as they interacted with each other, using three Microsoft Kinect v2 cameras."

At a later stage, the researchers manually analyzed and refined the skeletal data they collected to identify instances in which the Kinect sensor did not track movements properly. This incorrect data was then adjusted or removed from the dataset.

Unlike other existing datasets for training , AIR-Act2Act also contains representations of the movements that should be emulated or learned by a . More specifically, Ko and her colleagues calculated the actions that a  called NAO would need to perform based on its joint angles to emulate the non-verbal behavior of human participants interacting in their data samples.

"Previous research used human-human interaction datasets to generate two social behaviors: handshakes and waiting," Ko said. "However, larger datasets were essential to generate more diverse behavior. We hope that our large-scale dataset will help advance this study further and promote related research."

Ko and her colleagues published AIR-Act2Act on GitHub, along with a series of useful python scripts, so it can now be easily accessed by other developers worldwide. In the future, their dataset could enable the development of more advanced and responsive humanoid robots for assisting the elderly that would be able to reproduce human non-verbal social behaviors.

"We are now conducting research exploring end-to-end learning-based social behavior generation using our dataset," Ko said. "We have already achieved promising results, which will be presented at the SMC 2020 conference. In the future, we plan to further expand on this research."

Can the voice of healthcare robots influence how they are perceived by humans?

by Ingrid Fadelli , Tech Xplore

Robots are gradually making their way into hospitals and other clinical facilities, providing basic assistance to doctors and patients. To facilitate their widespread use in health care settings, however, robotics researchers need to ensure that users feel at ease with robots and accept the help they can offer. This could potentially be achieved by developing robots that communicate in empathetic and compassionate ways.


With this in mind, researchers at the University of Auckland and Singapore University of Technology & Design have been using speech synthesis techniques to create robots that sound more empathetic. In a recent paper published in the International Journal of Social Robotics, they presented the results of an experiment exploring the effects of using an empathetic synthesized voice on users' perception of robots.

"Our recent study is based on approximately three years of research aimed at developing a synthetic voice for health care robots," Jesin James, one of the researchers who carried out the study told TechXplore. "Past studies have shown that the type of synthesized voice used by robots can impact how users perceive them, which can encourage or discourage users from initiating interactions."

The speech research group at the University of Auckland and the Center for Automation and Robotic Engineering Science have been trying to develop health care robots that can assist people in care homes for several years now. Recently, they have been focusing their efforts on trying to identify voices that could make robots more acceptable in the eyes of humans they interact with.

"A lot of research and development efforts in robotics focus on broadening the capabilities of robots," James explained. "However, users may be entirely discouraged from using robots if they perceive a lack of reciprocal empathy. We felt that a robot's voice plays an important role in how people perceive it, which is what ultimately inspired us to carry out our recent study."

First, James and her colleagues tested the hypothesis that a robot's voice can impact how users perceive it by conducting a simple experiment using a robot called Healthbot. The robot's voice was that of a professional voice artist, who was recorded while reading dialogs in two tone variations: a flat monotone and an empathetic voice.

The researchers recruited 120 participants and asked them to share their perceptions after they had watched videos of Healthbot talking with these two different voices. The vast majority of participants said that they perceived the robot as more empathetic when it spoke using the more empathetic voice. These initial results encouraged the researchers to explore the possibility of producing a synthetic voice that reproduced the empathetic tone used by the professional voice artist.


"Our study had two key objectives," James said. "One was to determine what type of synthesized voice is best for creating a health care robot that is perceived as empathetic. Once we identified it, we tried to use speech synthesis techniques to produce this voice."

When they analyzed the findings of a short pilot study, the researchers realized that the emotions that most influenced whether a human user perceived a voice as empathetic or not were not the primary emotions (i.e., anger, sadness, joy and fear), but more subtle, secondary emotions. These are complex emotions that are often conveyed by the tone of voice of human speakers, which could be, for instance, apologetic, anxious, confident, enthusiastic or worried. This realization inspired James and her colleagues to compile a new dataset of speech recordings conveying these secondary emotions, called JLCorpus.

By analyzing speech samples from this dataset, the team was able to produce a model that outlined the emotional qualities that a synthesized voice should have to be perceived as empathetic by human listeners. This model accounts for characteristics such as pitch, as well as speech rate and intensity. They then produced a synthesized voice that matched the emotional qualities they identified.

Subsequently, James and her colleagues carried out a second perception test, during which users viewed videos of Healthbot speaking with the synthetized voice they had created and shared their perceptions of the robot.

"In this second perception test, participants saw a video of the health care robot speaking with the synthesized voice and rated the perceived empathy on a five-point scale based on the Motivational Interviewing Treatment Integrity (MITI) module," James said. "This is a five-point scale used to rate a clinician's empathy, and the same scale was used here with modifications done to suit the health care robot."

In the videos that the researchers showed participants, Healthbot had a neutral facial expression and its speech was not accompanied by any particular hand gestures. This means that it could only convey emotions and empathy via its voice. The vast majority of those who took part in the second test said that they perceived the robot as highly empathetic, rating it high on the five-point scale MITI module.

"Our findings suggest that people can perceive empathy from voice alone, without any supporting facial expressions or gestures," James said. "This implies that a robot's voice plays a key role in how humans perceive it. This voice is not just a medium of communicating with humans; it can actually impact their perceptions."

In addition to highlighting the important role that a robot's voice plays in how humans perceive it, the recent study carried out by James and her colleagues shows that subtle, secondary emotions are what ultimately make a voice sound more empathetic. These findings could pave the way towards new studies exploring secondary emotions, which have so far been seldomly investigated.

"These emotions are subtle in nature, can be culture-specific and are sometimes difficult to define and reproduce, but this is the exciting part about analyzing them," James said. "We are not exactly sure about what we could find and that makes it all the more interesting. There is a lack of resources and databases to study secondary emotions, so developing these resources would be the next step forward."

In the future, the synthesized voice produced by this team of researchers could be used to create health care robots that sound more empathic and human-like. Meanwhile, the researchers plan to continue exploring how humans convey subtle secondary emotions in speech, so that they can synthesize robot voices that are increasingly convincing and empathetic. They would also like to develop emotion recognition models that can automatically detect these emotions in the voice of human speakers.

"So far, we carried out perception tests using a video of the robot speaking to participants," James said. "We are now conducting perception tests in such a way that participants can actually sit near a physical robot and interact with it. We expect that the presence of the robot near the participants will impact their perception of the robot further."

Crabs are key to ecology and economy in Oman

by Royal Netherlands Institute for Sea Research

The intertidal mudflats of Barr Al Hikman, a nature reserve at the south-east coast of the Sultanate of Oman, are crucial nursery grounds for numerous crab species. In return, these crabs are a vital element of the ecology, as well as the regional economy, a new publication in the scientific journal Hydrobiologia shows. "These important functions of the crabs should be considered when looking at the increasing human pressure on this nature reserve," first author and NIOZ-researcher Roeland Bom says.


Blue swimming crab

The mudflats of Barr Al Hikman are home to almost thirty crab species. For his research, Bom, together with colleagues in The Netherlands and at the Sultan Qaboos University in Oman, looked at the ecology of the two most abundant species. Bom notes, "Barr Al Hikman is also home to the blue swimming crab Portunus segnis. That is the species caught by local fishermen. This crab uses the mudflats of Barr Al Hikman as nursery grounds."

The counts of Bom and his colleagues show, that there are millions and millions of these crabs in Barr Al Hikman. They are food to hundreds of thousands of birds, both migrating species, as well as birds breeding in the area, such as crab plovers. The crabs live in holes in the ground. They forage on the seagrass beds that are still abundant in Barr Al Hikman. "Apart from the high primary production (algae) in Barr al Hikman, this reserve is also well suited for crabs because of the vastness of the area," Bom assumes. "The slopes of the mudflats are very gentle, so at low tide, the crabs have an immense area at their disposition."

Eco value

The value of the crabs is not just ecological, Bom stresses. "Local fishermen that catch the blue swimming crabs, distribute them not only through Oman, but also through the rest of the Arabian Peninsula and even to Japan. At approximately € 2,- per kilo, these crabs represent an important economic pillar, both under the region around Barr Al Hikman, as well as for the whole of Oman."

Reserve

The protection of the reserve of Barr Al Hikman is limited to national legislation. Efforts to acknowledge this reserve under the international Ramsar-convention were never effectuated. There is, however, increasing human pressure on the mudflats of Barr Al Hikman, the authors describe, that would justify further protection. For example, there are well-developed plans to start shrimp farming around this intertidal area. "When looking at the cost and benefits of these activities, it is important to look at the role of this reserve in the local ecology, as well as in the broader ecology of the many migratory birds that use the area," Bom says. "Moreover, our research shows that the unique ecosystem of Barr Al Hikman plays a key role in the economy as well."
