Real estate investment trust (REIT) acquisition associated with hospital closure and bankruptcy

A study found that hospitals sold to REITs were more than five times as likely to close or file for bankruptcy compared to similar hospitals. The researchers analyzed nearly 20 years of data and found no immediate improvements in finances or quality, but long-term harms, including increased risk of closure or bankruptcy.

ESMT Berlin study: What makes a first offer successful in negotiations

The ESMT Berlin study analyzed 90 studies with over 16,000 participants to conclude that those who make the first offer and come well-prepared tend to achieve better outcomes. Higher first offers often lead to better final outcomes, but there are limits to this approach, particularly when demands are very high or unrealistic.
