AI Workday

Our workdays have seen considerable changes throughout the last few days. The home office boom has allowed employees to work for extended hours from home. The there is an abundant literature on the effects of home office work on well-being or the work-life balance. Productivity gains could be reaped by employers and a better work-life balance was a lasting advantage for employees.
The increased use of AI specific to some occupations has introduced a new form of added  productivity for some occupations or professions, AI as complementarity, whereas other occupations suffered a higher risk of being substituted by AI applications.
Based on time diary data, the study by Wei Jiang et al. (2025) reports that users of AI have longer work time and reduced leisure time. Competitive labor markets increase the pressure to put in even higher hours of work. Nerds, just like workaholics, are likely to be drawn into excessive hours of work with increased health risks. Enterprises and consumers appear to be gaining more than the employees, who are at a higher risk of loosing out on their work-life balance over time.

Travel Trumped

The travel and tourism sector of the U.S economy takes quite a hit from Trump‘s anti Canada and Europe tariffs and rhetoric. The Wall Street Journal (2025-6-3) reports data until May 2025  which show a 6% decline in international air travel and a 12% reduction in air arrivals from Europe (reference same period last year). Canadians seem to reduce their travels to the US as well, hitting many regions just across the long joint border. Airline bookings are an early warning indicator, but the more drastic figures are to be expected from the loss of spending tourists do not dispense in the US any more. Additionally, sizeable shares of US tourists travel to other countries due to the disgusting Trump rhetoric and spend their holiday budgets elsewhere. Trump‘s tariffs has focused a lot on redressing the trade balance of goods, but the balance of services like in tourism is worsening day by day now. The political economy of tariffs has multiple feedback effects which are quite hard to predict.

Citizen Walk

Capitals like Paris and Berlin make great efforts to improve the walkability of their cities. After decades of focus on automotive traffic and mobility and the detrimental effects on health for several generations of people, the awareness that walking citizens are part of the solution is spreading. Citizens of Paris voted in a referendum to stop circulation of cars in 500 more streets. In Berlin pedestrians unite to mobilize more people to take to the streets as well and reclaim walking space. In high density spaces like metropolitan areas it is possible to reach all major amenities within a reasonable walking distance. The more spread out suburban area, however, leve fewer options to walk and carry your shopping or do your dily commute to work while walking. Fewer cars and pharmaceutical products sold would mean less „artificial economic growth, but more healthy and happy citizens. It will take decades again to realize such visions.

Paris Gare

Train stations in metropolitan inner cities are hot spots of traffic and mobility. The number of people passing through these exchanges are impressive. Public transport systems are continuously put to the test of their capacity to handle passengers who want to get from A to B the fastest way possible. In Paris the RER lines, metro and buses to a great job in handling the affluence of passengers. The comparatively small number of passengers arriving and departing nyy taxi, however, still take a disproportionate amount of space. That’s part of the differentiation or inequality of mobility in Paris. Person‘s in need of assistance should have special access to central points of mobility like train stations. Everybody else could rely on shared modes of transportation otherwise the millions of inhabitants will not be able to get around in a comfortable way.

Memories updated

In Berlin and many other German cities it is a regular practice to scrutinize the memory inscribed into street names. In order to correct the honors given to persons with a past as fascist or responsible for mass killings street names were changed at several points in the history of the city. Streets named after battle fields, for example, are a continuous point of discussion. It is important to keep the perspectives of victims in mind. Therefore, changing street names is a little contribution to rethink the role of places and persons. Such changes are sometimes very controversial as people become accustomed to names, some might even not care much at all. Recognition and responsibility, however, have a lot of currency in historical perspective. Overpainting like in the paintings from Gerhard Richter has an important function in society and can be one way of coping with the demons of the past.

Retirement Recruitment

The debate that later retirement of seniors reduces the hiring of youth has received new attention. Paul Mohnen published a paper on the “retirement slowdown on the US youth labor market” , which demonstrates this “crowding out effect”. Moreover, the recruitment of middle aged workers is also affected, as job changes slowed down for these age groups. The surprising finding is that higher skilled youth suffers the largest reduction in employment opportunities and become “pulled” into lower skilled jobs as jo offers for lower skilled persons remained high during the observation periods (until 2017!). This evidence suggests that the well-documented firm-level effect of fewer retirement means less recruitment holds also for society as a whole. Knowing that recruitment during a recession affects young workers more than persons already in employment, the macro level effects in 2025 will be rather unfavorable for young labor market entrants.

Draft Lottery

For decades the “intergenerational effects of the Vietnam draft on risky behaviors” has been overlooked. Deza and Mezza (2025) identified several changes in parenting styles (PS) due to existence of a draft lottery. PS like uninvolved, permissive, authoritarian become more frequent. Similarly, risky behaviors of their children like smoking, drinking and drug abuse tend to increase. According to this new evidence on an old strategy to recruit military personnel the effects are not only directly on the persons drafted, but have lasting consequences onthe next generation as well. This increased overall the burden of going as well as preparing for war in the societies concerned. In view of the Russian aggression on Ukraine territory the consequences for both countries are considerable and shall be transmitted to future generations as well. Even neighboring countries fear and feel the heat of recruitment for armed conflict.

Artist Development

For many artists it takes years before they find their idiosyncratic style. Testing different forms of art before zooming in on a particular style of art is the  common trajectory for most artists. Maybe the art marker and collectors of art are in search of a “defining style” for an artist so the uniqueness becomes more easily identifiable. Being part of a group of artists has been beneficial as well. The “Neue Nationalgalerie” in Berlin makes this development of an artist, in this case Lygia Clark transparent through the organization of a retrospective devoted to her evolution from abstract paintings towards participative and more organic forms of art. Berlin offers to interact with the pieces at the exhibition. You become part of the exhibition and the happening of art instantaneously. The form stays the same, the persons interacting change permanently. The piece of art is never the same. Just the idea of it thrives. In the Corpo Colletivo the performers wear an overall, all of them are linked to each other and movements happen organically as a group rather than individually. This is like a tutorial in sociology as individuals move as part of a collective body and feel the embeddedness and multiple links to other persons (Image: Corpo Collectivo 1970, exhibit in Berlin 2025)

Killing fields

According to “Le Monde” dated 2025-5-26 the persons who died in the war initiated by Putin amount after 3 years to 250.000. The numb of injured soldiers would be 3-4 times as high. The loss of lives and tarnished life expectancy of persons involved in combat adds up to a huge loss for the Russian people. Being misled by political and military leaders, apparently substantial numbers of recruits for all sorts of services face the choice between the combat field or desertation. Tough choices which remind us of the moral conflict raised already during peace times if you were refusing to join the compulsory military service. Western people are better prepared for such moral dilemmas than the glorification of war in the Russian society. Of course, certainly in Germany we are thankful for the hardships the Russian army and people had to endure during the 2WW. Liberation Day would not have happened without the Soviets, Russia and Ukraine plus many other nations fighting until Nazi- Germany surrendered. The positional battles of the Great War seem to be back again enhanced with a war of drones. The killing fields for a generation of Russian troops is completely self inflicted. How many thousands Putin needs to acknowledge this cruelty? (Image exhibition by Yoko Ono Berlin Gropiusbau 2025-5).

Odessa Berlin Odessa

With a sense of partnership, it is possible to travel between Odessa and Berlin in the “Gemäldegalerie” in Berlin 2025. Due to the war of Putin in Ukraine the “Museum of Western and Eastern Art” in Odessa had to relocate its treasures to safe places. The Gemäldegalerie offers a chance to view the splendid collection nevertheless. The curators’ team in a spirit of “art intelligence” propose, in a splendid way, most oeuvres from Odessa next to an example by the same painter from the Berlin collection. The visitor leaves the exhibition enriched by an experience of “jumelage” (engl. sister cities) of partnerships between museums, cities and their people.
In fact, we have shared the same imagery or visual heritage in Europe for centuries . The collections of paintings ranges from the 16th -19th century art  or from Frans Hals to impressionist influences.
We shall cherish the return of the collection to Ukrainian Odessa as soon as possible. The image below shows the places of origin (yellow dots) of the art works of the Odessa collection across centuries (map from the exhibition).
