 The MiP Workshop is an annual meeting organized by the Matching in Practice network of European researchers working in the research field of Matching Theory and Market Design.

This year’s MiP workshop is funded by the following projects: Prin2022 “Externalities and fairness in allocations and contracts” (CUP J53D23004650006 – ID 2022HLPMKN) and PrinPNRR2022 “Incentivizing participation of compatible pairs in Kidney Paired Exchange Programs” (CUP J53D23015460001- ID P2022P5CHH), both funded by the European Union – Next Generation EU.

The Organizing Committee includes the Messina Unit Manager of the aforementioned projects, Prof. Antonio Miralles Asensio, and the Principal Investigators of both funding projects, respectively Prof. Maria Gabriella Graziano (University of Naples Federico II) and Prof. Antonio Nicolò (University of Padua). External members of the Scientific Committee are Prof. Caterina Calsamiglia (IPEG and ICREA, Spain), Prof. Rustam Hakimov (Université de Lausanne, Switzerland) and Prof. Péter Biró (Hungarian Academy of Sciences, Hungary).

Air cargo: fish and electronics (and flowers and armaments)

 Haaretz has the story:

120 Tons of Missiles and Salmon: A Rare Trip on Board an Israeli 747 Cargo Plane by Anshel Pfeffer and Avi Scharf

"Whenever you receive a package ordered online from abroad or eat semi-fresh imported food, there's a good chance it was transported by a 747. Over 300 of these aircraft are still flying cargo across the world despite the fact that most of them are over 20 years old. There's a good reason for this: There is no aircraft in production today that's capable of flying over 120 tons of cargo (jumbos can manage up to about 130 tons), and there's nothing even remotely similar on the drawing board. Thus, 56 years after it first entered commercial service, the 747 is still flying freight – with no retirement in sight.
...

In terms of volume and weight, about 99 percent of international cargo is transported by sea or overland, in trucks and trains. The lone percent of physical goods flown on cargo planes, however, is worth more than one-third of global trade, or around $6 trillion a year. That includes electronic goods, pharmaceuticals and blood plasma, perishables such as fresh seafood, and of course any shipment that needs speedy delivery, like your latest order from Amazon or AliExpress, for which you've agreed to pay an added premium.


"In 2023 the global expenditure involved in shipping all airfreight crossed the $300-billion mark for the first time. It will hit $400 billion before the end of the decade. And that's why the old 747 will still be flying for years to come.

...
“ Pandemics and wars are the best of times for cargo airlines. Normally over half of the volume of airfreight is carried on passenger flights, in the hold next to passengers' luggage. There isn't much room there, for just a few tons at most for the extra cargo, but there are many more passenger flights than cargo flights. When passenger service is canceled as it was around the world during the COVID pandemic, or to and from Israel after October 7 – while at the same time people cooped up at home order a lot more online – the cargo fleets have to supply the missing haulage capacity. In 2023, nearly half the cargo into and out of Israel (151,000 tons out of 334,000) was transported on passenger flights. In 2024, after a full year of war during which non-Israeli airlines barely flew here, that proportion dropped to a little over one-quarter (95,000 tons out of 348,000). That's when the 747, which back in the early 1960s was first envisaged as a freighter, really came into its own.

...
"The 747 freighters that still fly around the world comprise around a quarter of all global cargo fleets. But thanks to their size, they carry half the volume of all goods shipped by air. Which comes in handy especially at time of war when Israel cannot wait for large quantities of munitions and other military equipment to be transported by sea."

Assisted living facilities: U.S. eldercare

As people live longer, we need to think harder about end-of-life and late-in-life care of all sorts.

 The Guardian has the story (much of which focuses on a particular difficult situation):

In the US, not even $11,000 a month can buy you dignity at the end of your life  by Laura Fraser

"how much longer will we accept a future where most of us lose our sense of human worth in old age?"

...

"Currently, about 65% of US elders are cared for by their families at home. For 13% of those who aren’t living with family, the gap is partially filled by assisted living establishments.

...

"Nursing homes, assisted living and memory care (special units for people with dementia) are interchangeable in many people’s minds. But there are big differences. Nursing homes, funded by Medicare and Medicaid, are federally regulated. Assisted living and memory care are state-regulated, and mostly paid for out of pocket; some states have subsidies for certain conditions, so about 20% of all assisted living costs are paid for by Medicaid. The median cost of care in the US is $5,900 a month, but ancillary services provided on top of that base rate, including extra skilled nursing care, and can bring that cost up to $20,000 a month.

...

"Assisted living and memory care communities are covered by a range of 350 licensing regulations that vary widely from state to state – but with little oversight or enforcement of what few regulations exist. Most regulations don’t require minimum staffing ratios, or are worded as “sufficient” to meet residents’ needs. While this standard is vague, some advocates say that being more prescriptive would be problematic given staffing availability, costs and residents’ needs. Caregivers are typically required to have only a few hours’ training; only about half of communities employ a nurse, usually voluntarily. State and regional long-term care ombudsmen have the right to enter and investigate and informally mediate complaints at these residences, but they have no ability to enforce regulations, other than making a complaint to the state licensing agency.
