Politically connected corporations received more exemptions from US tariffs on Chinese imports, study finds


Exemption grant process functioned as a “spoils system” rewarding political supporters and punishing opponents



Lehigh University



Research recently published in The Journal of Financial and Quantitative Analysis reveals that politically connected companies were significantly more likely to receive valuable exemptions from the tariffs imposed on U.S. imports from China during the Trump administration.

The authors, Veljko Fotak (SUNY Buffalo), Grace Lee (Fordham University), William Megginson (University of Oklahoma), and Jesus Salas, associate professor of finance (Lehigh University), found that companies that made substantial investments in political connections to Republicans prior to and during the beginning of the Trump administration were more likely to secure exemptions for products otherwise subject to tariffs.

Conversely, companies that made contributions to Democratic politicians had decreased odds of tariff exemption approval.

“Our findings reveal that politicians not only use exemptions to reward their supporters, but also withhold exemptions to punish supporters of their opponents,” Salas said. “The tariff exemption grant process functioned as a very effective spoils system allowing the administration of the day to reward its political friends and punish its enemies.”

The Tariffs and Exemption Process

Enacted in 2018, the “Section 301” tariffs increased the cost of a wide range of goods imported from China by an average of about 20%. Announced as retaliation to Chinese trade policies that were seen as harmful to U.S. business interests, the tariffs initially covered $34 billion worth of goods and were expanded over a period of 14 months to cover approximately $550 billion in imports.

The U.S. government created a system for companies to request an exemption from tariffs. The government considered the following factors when adjudicating the exemption applications:

  • Whether tariffs would impose significant harm on American business interests
  • Whether substitute products were available outside China
  • Whether the products were “strategically important” to China

According to the researchers, the Section 301 exemption process was unusual in being administered completely by the Office of the U.S. Trade Representative (USTR), without Congressional oversight and without an appeal process.

This process stood in contrast to other programs, including those for steel and aluminum tariffs that were also implemented in 2018. Exemptions for the steel and aluminum tariffs were administered with greater transparency under the watch of a Commerce Department Inspector General and with Congressional oversight.

Unlike the Section 301 tariffs, the researchers found no significant relation between companies’ political activity and exemption decisions regarding the steel and aluminum tariffs.

Political Influence and ‘Quid Pro Quo’

The study analyzed 7,015 applications for exemptions filed with the USTR, political activity data from the nonpartisan research group OpenSecrets and business information from the Compustat database to determine the extent to which lobbying and campaign contributions influenced tariff exemption outcomes.

A clear theme emerged: Spending to build political connections was a good investment for U.S. companies — if you spend it on the right candidates. A longstanding puzzle in the literature on political contributions has been understanding why firms don’t donate more. Results from the study, Salas said, suggest that contributions to the wrong party could harm firms.

Of the exemption applications reviewed, only 1,022 (14.5%) were approved. Researchers found that, in addition to submitting persuasive applications in conformity with the guidelines, companies could increase their odds by investing more in lobbying.

Among companies in the dataset, a one standard deviation increase in lobbying expenditures boosted approval chances by 2.15 percentage points.

Companies that had previously contributed to Republican candidates via their Political Action Committees (PACs) improved their odds even more. A one standard deviation increase in contributions to Republicans raised the likelihood of exemption approval by 3.94 percentage points. Conversely, the same increase in contributions to Democrats decreased approval odds by 3.4 percentage points.

Given that roughly just one in seven applications were approved, these advantages were substantial.

According to the authors, political connections generally yield benefits through two channels: helping companies navigate regulations (the “information channel”) and rewarding firms for their political support (the “quid pro quo channel”). Identifying why specifically firms benefit from contributions is of utmost importance, they said.

“While our findings linking lobbying expenditures with a higher probability of approval are consistent with both channels, our findings linking contributions to the party in power to a higher chance of approval and contributions to the opposition to a lower chance are strongly indicative of quid pro quo arrangements,” Salas said.

“While there is ample evidence in the broader literature that firms benefit from their political connections — with quid-pro-quo arrangements on both sides of the political aisle — this study is the first to document punishment for supporting the opposition.”

According to OpenSecrets, U.S. companies spent over $3 billion on lobbying in 2016, in addition to funneling hundreds of millions of dollars to political campaigns via PACs. In 2024, lobbying expenditures totaled more than $4 billion.

Researchers also examined other forms of political influence, including personal campaign contributions by company executives and donations to influential representatives, such as those on finance and leadership committees. Both of those actions further enhanced the likelihood of securing exemptions.

However, employing former government officials as directors, à la the “revolving door” between the corporate world and the federal bureaucracy, did not have a significant impact.

While political connections played a substantial role in exemption decisions, the authors noted that the stated criteria were not entirely disregarded, and applications that met the criteria were more likely to be approved.

Economic Impact and Market Reactions

Economists with political leanings on either side of the aisle tend to oppose tariffs because they often lead to retaliatory measures, higher prices and economic losses. Past studies cited by the authors document that tariffs have a strong negative effect on the U.S. economy, leading to monthly real income losses of $1.4 billion and a net economic loss of $7.2 billion.

But companies that received exemptions from the China tariffs benefited greatly. The study found that announcements about exemptions were linked to abnormal returns of approximately 55 basis points in stock prices within the five-day window around the announcement.

For a median company in the sample, one with a market capitalization of $10 billion, this reaction represented a valuation increase of about $51 million.

“The biggest surprise to us was that the U.S. government was punishing firms that contribute to Democrats,” Salas said. “There is plenty of evidence that political connections are valuable to firms. The finding that the government could be vindictive to supporters of the opposition was very surprising to us.”

 

The future of mobile gaming: less latency, more fun thanks to edge computing


The study explores how edge computing can transform Gaming as a Service (GaaS) by significantly improving performance



IMDEA Networks Institute





A recent study titled “Gaming on the Edge: Performance Issues of Distributed Online Gaming”, published at the IFIP International Conference on Networking 2024, proposes an innovative model to enhance the experience of online gaming, particularly on mobile devices. Led by an international team of researchers—including Professors Marco Ajmone and Vincenzo Mancuso from IMDEA Networks—the study explores how edge computing can transform Gaming as a Service (GaaS) by significantly improving performance.

The study shows that by processing user data on nearby servers located within mobile networks (such as 5G) instead of the cloud, the time it takes for a player’s action to travel from their device to the server and back is significantly reduced. According to Ajmone, “this approach shortens the distance that data travels, resulting in lower latency and a reduced likelihood of link congestion.”

What are the benefits?

The main advantage is a faster and smoother experience, especially for game genres where every millisecond counts, such as real-time shooters. “Reduced latency is key in games where reaction time determines the player’s success,” says Mancuso. Additionally, video quality is improved because “the shorter the network path for the game’s video stream, the higher the quality of video encoding that can be used.”

Moreover, the model offers a valuable tool for managers of GaaS applications. By enabling them to choose the best performance configuration when new groups of players join, the system can ensure optimal operation and provide gamers with the best possible experience.

A promising future for Gaming as a Service

The success of this technology also depends on collaboration between video game developers and network operators. “Developers need to implement distributed versions of their game engines, and network operators must deploy edge computing facilities open to third-party service providers, such as game providers,” explains Ajmone.

As edge computing becomes more accessible, this model could mark a turning point in how we play games and interact with new digital technologies, transforming the entertainment experience for millions of users.

 

Optimism can boost saving, especially for lower-income individuals


‘Rose-colored glasses’ motivate people to save for future despite present challenges, study suggests


SO CAN THIS




American Psychological Association




WASHINGTON – Being optimistic about the future may help people save more money, and the effect appears strongest among those with lower incomes, according to research published by the American Psychological Association.

The study found that people who scored higher on measures of “dispositional optimism” -- the tendency to expect positive outcomes -- saved more money over time compared with their less optimistic peers.

The research was published in the Journal of Personality and Social Psychology.

"We often think of optimism as rose-colored glasses that might lead people to save less for the future," said lead author Joe Gladstone, PhD, of the University of Colorado Boulder. "But our research suggests optimism may actually be an important psychological resource that helps people save, especially when facing economic hardship."

Gladstone and his colleague Justin Pomerance, PhD, of the University of New Hampshire, analyzed data from eight large population surveys in the U.S., the U.K., and 14 European countries, with more than 140,000 total participants. All the surveys included some measure of participants’ optimism, asking participants to rate their agreement with statements such as “I'm always optimistic about my future,” “Overall, I expect more good things to happen to me than bad,” or “In uncertain times, I usually expect the best.” The surveys also asked participants to report their income, savings, and in some cases total assets.

Three of the surveys were cross-sectional, meaning that participants were surveyed at one point in time. Five were longitudinal, in which participants were surveyed more than once over a period of years.

Across all the surveys, the researchers found that participants who were more optimistic reported having more savings, on average. For example, a one-standard-deviation increase in optimism correlated with a $1,352 increase in savings for households with the median savings balance of $8,000. This held true even when the researchers controlled for demographic and other variables that could influence both savings and optimism, such as age, gender, relationship status, parental status, childhood socioeconomic status, health, employment status and the “Big Five” personality traits (conscientiousness, extraversion, agreeableness, neuroticism and openness to experience).

“After controlling for those variables, the effect size of optimism was similar to what previous research has found for conscientiousness, a personality trait that’s widely recognized for its positive influence on financial outcomes,” Gladstone said. “Optimism also appears to exert a slightly stronger influence on savings behavior than financial literacy and risk tolerance.”

The effect of optimism on saving behavior was strongest for people with lower incomes, the researchers found. That makes sense, said Gladstone, because at higher income levels, people often have more ways to save automatically, such as through mortgage payments (which contribute to home equity) and direct retirement contributions. Or they may simply be able to save because they don’t need to spend all the money they earn.

"For someone living paycheck to paycheck, saving can feel futile," Gladstone noted. "But an optimistic outlook may provide the motivation to set aside money despite present challenges."

The study has implications for financial education programs and policies aimed at boosting saving rates, particularly among economically vulnerable populations. Incorporating optimism-building techniques alongside traditional financial literacy training could prove a powerful combination, according to the researchers.

"Ultimately, a mindset of hope for the future, paired with the skills to manage money wisely, may be key to helping more people build financial security," said Gladstone.

Chameleon shrimp can camouflage themselves even in invasive species of algae, study shows

Small shrimps of the genus Hippolyte have the ability to change color to camouflage themselves in the algae where they live and escape predators. Depending on the algae they are in, they can turn red, green, brown or transparent.

A study published in the Journal of Animal Ecology shows for the first time how these crustaceans interact with invasive algae. The results also show that they can camouflage themselves in algae from other oceans with which they did not evolve together.

The authors, from the Federal University of ABC (state of São Paulo, Brazil) and the University of Exeter (United Kingdom), tested how the species found at European beaches, the chameleon shrimp (Hippolyte varians), interacts with two exotic algae, one from Asia and the other from Australia.

The European species, which is about 3 centimeters long, is evolutionarily related to the carnival shrimp (Hippolyte obliquimanus), which is common along the north coast of São Paulo (read more at: agencia.fapesp.br/25091).

“When the chameleon shrimp encounters two different algae, it doesn’t matter which is native and which is exotic, it chooses the one that offers the best color match so it can hide,” reports Rafael Duarte, first author of the study, which was conducted during his postdoctoral studies at the Center for Natural and Human Sciences (CCNH) at UFABC with a scholarship from FAPESP.
  
The collections and experiments were conducted during Duarte’s internship at the University of Exeter under the supervision of Martin Stevens, co-author of the article.

The researchers collected the shrimp and the algae they lived on from tide pools formed on rocks at two beaches in Falmouth, southwest Britain.

In the laboratory, the animals were placed in a box with two algae to hide in, one native and one exotic. Combinations of two of the four species studied were tested, always one native (green or red) and one exotic (brown or pink).

“The brown one is an Asian sargassum species that has increased its presence in the last decade and is causing problems in several places in Europe. It’s taking over the habitat of native species, which are being restricted to deeper areas. However, it has proven to be an excellent shelter for shrimp,” says Duarte, currently a researcher at the University of Aveiro in Portugal.

Complexity rather than color

In the Y-shaped boxes, the shrimp were observed for ten minutes. In most cases, they chose one of the two algae offered and remained there until the end of the experiment.

In general, there was no preference for choosing the native algae, but rather the algae where they could best hide. The green shrimp showed no preference between the green native algae and the brown exotic sargassum.

But when they encountered the native red algae and the exotic brown algae, the shrimp preferred the sargassum. The researchers believe that when there is no color match with the native plant, the structure of the invasive plant serves as better protection, favoring its choice.

“While the native green algae are quite leafy and flat, the sargassum has a more complex three-dimensional structure, like a fern. In nature, this probably makes it easier for them to protect themselves better from predators, even if the colors don’t quite match,” Duarte points out.

Moreover, he adds, the native green algae are quite seasonal. In the periods when they’re not as available, the shrimp can use sargassum, which is more stable throughout the year.

It takes up to 30 days for the chameleon shrimp to turn the same color as the algae. The researchers observed that the color change from red to green is faster than the other way around. The most likely hypothesis lies in the pigments inside the cells that give the animals their color, called chromatophores.

Work on pigmentation carried out by other groups shows that red animals have all the necessary pigments in their chromatophores and only need to get rid of the other colors to change their color.

In the case of green animals, however, the red pigment must be acquired in order to change color, which requires more time and energy from the organism. In the case of chameleon shrimp, the researchers believe that it is necessary to eat red or pink algae in order to acquire the pigments of these colors.

However, a number of questions remain about this complex interaction. One of them is how the shrimp recognize the algae. Previous studies have shown that the shape of the algae is important, but it is not certain that the choice is visual. The group is now investigating whether algae have chemical signals that can be detected by crustaceans, and whether the presence of pollutants in the water can alter this perception.

“Although the interaction with exotic algae doesn’t seem to affect the species’ ability to camouflage itself, we don’t know the long-term effects of the presence of these invaders. Throughout the world, invasive species are wreaking havoc on ecosystems. We need to monitor to better understand these relationships,” he concludes.

Urgent action needed to keep Europe polio-free, warn heads of ECDC and WHO Europe



An unusually high amount of poliovirus detections in several European countries in recent months has underscored the importance of keeping Europe polio-free



Reports and Proceedings

European Centre for Disease Prevention and Control (ECDC)





An unusually high amount of poliovirus detections in several European countries in recent months has underscored the importance of keeping Europe polio-free, according to an editorial by European Centre for Disease Prevention and Control (ECDC) Director Pamela Rendi Wagner and World Health Organization (WHO) Regional Director for Europe Hans Kluge, which was published on Eurosurveillance. ‘A future without polio remains our goal, but it is by no means a certainty’, warn Rendi-Wagner and Kluge.

Every country must remain vigilant to detect the presence of polioviruses through sensitive surveillance systems, prepared to act quickly if any circulation is detected, and committed to sustain high vaccination coverage in every community every year until global polio eradication has been achieved,’ said Kluge and Rendi-Wagner. This reiterates the path laid out in the European Immunization Agenda 2030, the GPEI Polio eradication strategy, and the Global Polio Surveillance Action Plan.

Ongoing risk highlighted by recent detections

While polio has been a threat to the health and wellbeing of children for centuries, it is a mostly forgotten disease for the vast majority of people in Europe. Thanks to successful vaccination programmes, extensive surveillance and outbreak response, Europe has been polio-free since 2002.

However, the virus will continue to be imported into Europe as long as it circulates globally. Pathogenic poliovirus has been detected in at least one country in Europe every year from 2015 through 2022. More worryingly, vaccine-derived poliovirus type 2 was detected in 2024 in the wastewater systems of 14 cities in 5 countries, namely in Spain, Poland, Germany, the United Kingdom, and Finland.

These viruses are linked to a lineage that was first detected in Nigeria in 2020, and which has travelled to other 21 countries in Africa, causing outbreaks in 15 of them. Genetic sequencing analysis indicates that before it had been detected in Europe, the virus had been circulating for a year elsewhere.

There is no evidence that there has been widespread circulation of the virus in Europe due to these importations. However, these may and do lead to outbreaks if people who are unvaccinated are exposed to the virus, as recently seen in Tajikistan, Ukraine, Israel and the United Kingdom.

Public health action urgently needed

Therefore, Rendi-Wagner and Kluge emphasise the need to maintain high national vaccination coverage across all populations. While the five countries that detected polio virus in 2024 have maintained high immunization levels, they have also reported disparities in some communities, which remain vulnerable to infection as a result. ECDC estimates that 2.4 million children in the EU/EEA may not have received the course of vaccinations required for protection between 2012-2021, with an additional 600 000 children who may have missed their vaccinations in 2022-2023.

ECDC has published a Rapid Risk Assessment on these detections recommending priority actions to be urgently taken to prevent and curb possible transmission of polioviruses. WHO Europe has also published guidance to help countries identify, address and track disparities in vaccination levels.

Kluge and Rendi-Wagner have also underlined their commitment to cooperate closely to support national and local public health authorities in their efforts to curb the virus. This support includes technical guidance and resources for surveillance and outbreak response, facilitating data exchange and genetic sequencing of virus strains, and assisting in targeted risk communication and community engagement strategies to improve vaccination coverage. ‘Europe remains committed to do its part in the context of all relentless global efforts in this direction and has full capacity to do so successfully,’ said Kluge and Rendi-Wagner.

 

Wildfire smoke can carry toxins hundreds of kilometers, depositing grime on urban structures, surfaces: research

Hamilton, ON, Jan. 30, 2025 – Researchers have shown that plumes of wildfire smoke can carry contaminants hundreds of kilometres, leaving a toxic and lingering footprint which has the potential to be re-released into the environment.

 

The frequency and severity of wildfires is expected to continue increasing due to climate change. In recent weeks, catastrophic wildfires have devasted Los Angeles, scorching tens of thousands of acres. 

 

Canada’s 2023 wildfire season was the most destructive ever recorded, with an estimated 18.5 million hectares burned. The 2024 season was the second worst on record, with more than 5 million hectares burned according to the Canadian Interagency Forest Fire Centre, which tracks national statistics.  

 

Wildfire events may become an increasingly dominant and troubling source of pollution in urban areas, say researchers. 

 

Wildfire smoke features a complex mixture of pollutants, including polycyclic aromatic hydrocarbons (PAHs), a class of carcinogenic compounds that can also cause mutations in nature. PAHs are produced whenever incomplete combustion occurs, including when wood burns.

 

In the new study, published today in the journal Environmental Science & Technology, researchers at McMaster University report the potential impact of PAHs extends far downwind of wildfires, even hundreds of kilometres.

 

“This study was motivated by the large increase in wildfire frequency and severity in Western Canada,” explains Iris Chan, a graduate student in the Department of Chemistry & Chemical Biology and lead author of the study. “There is a great deal of public awareness and research on air quality related to North American wildfires, but the long-term impact of smoke drifting into cities is virtually unknown.” 

 

Urban landscapes are dominated by impermeable structures and surfaces such as buildings and roads, she explains. Over time, these surfaces accumulate what is known as “urban grime,” a buildup of deposited particles and other chemical compounds that can hold and re-release pollutants such as PAHs.

 

For this study, researchers enlisted volunteers in Kamloops and Calgary to collect samples in their backyards from August to November 2021. 

 

They set out specially designed kits containing glass beads, which mimic impervious urban surfaces like windows. The samples were regularly collected and analyzed at McMaster.   

 

The team looked for correlations between surface-grime PAHs and evidence of fire activity in measurements of local air quality such as carbon monoxide and fine particulate matter.

 

In the Calgary samples, researchers found toxin levels nearly doubled when smoke from fires in neighbouring Saskatchewan arrived from about 500 kilometres away. There were no other large-scale pollution events in Calgary at that time, suggesting the increase was linked.

 

In Kamloops, they pinpointed a sharp increase in toxins even when there were no significant wildfire events in the region. Based on the specific composition of samples, researchers concluded the uptick was due to a hyper-local burn, likely a neighborhood campfire. 

 

“We should be mindful that the minor things people do every day, like using their barbeque or having a campfire in the backyard, can have a significant and long-lasting impact on their local environment,” says Sarah Styler, who supervised the study and holds the Canada Research Chair in Atmospheric Chemistry at McMaster.

 

The accumulation problem grows worse when there isn’t sufficient rainfall to wash away the grimy buildup. A reservoir of toxins can, in principle, grow for long periods.  

 

“We would then expect precipitation to release pollutants into stormwater runoff, with the potential for adverse consequences for downstream water bodies, sediments and aquatic life,” says Styler.

 

The team is currently following up by analyzing samples from multiple cities in Canada and the United States collected during the 2022 wildfire season.  Additionally, they have recently begun a pilot project with Environment Hamilton to collect and analyze dust and grime samples in city neighbourhoods to determine how much is falling in different areas and what it might contain.
