Acquisitions of medical practices by health care systems, particularly tax-exempt health care systems, appear to be on the rise currently. This is because health care systems throughout the country are continuing their strategic efforts to position themselves to be more competitive in the markets that they serve. Motivations for such acquisitive transactions vary from circumstance to circumstan...

BACKGROUND Symbols have been used in health state valuation studies to help subjects distinguish the severity of various characteristics of a given health state. Symbols used in such studies need to be evaluated for their cross-cultural appropriateness because a given symbol may have different meanings or acceptability in different cultures, which may affect results of such studies. OBJECTIVE...

We study the problem of allocating indivisible goods among strategic agents. focus on settings wherein monetary transfers are not available and each agent's private valuation is a submodular function with binary marginals, i.e., agents' valuations matroid-rank functions. In this setup, we establish notable dichotomy between two most well-studied fairness notions in discrete fair division; speci...

This paper discusses the standard welfare economics assumption anthropocentric welfarism, i.e. that only human well-being counts intrinsically. New survey evidence from a representative sample in Sweden is presented, indicating that anthropocentrism is strongly rejected, on average. However, most people appear to have a consequentialistic ethics, in line with conventional welfare economics. The...

The Russia-Ukraine Crisis in 2022 adversely affected the business performance of PT Indofood CBP Sukses Makmur Tbk (ICBP), largest noodle manufacturer Indonesia, due to volatile wheat prices. During Q2, ICBP witnessed a 16% growth net revenue but substantial 40.1% decline profit, primarily attributed escalating commodity This negative trend persisted Q3, resulting significant 33.4% decrease pro...

This paper discusses a fundamental market failure regarding environmental conservation, and how the problem can be solved by appropriate policies. A "seller" (or owner of a tropical forest) may be motivated to conserve if a "buyer" is expected to pay. The buyer, however, does not find it necessary to pay as long as the seller conserves in any case. This contradiction implies that the forest wil...

In the multiple-partners job market, introduced in ( Sotomayor, 1992 ), each firm can hire several workers and worker be hired by firms, up to a given quota. We show that, contrast what happens simple assignment game, this extension, firms-optimal stable rules are neither valuation monotonic nor pairwise monotonic. However, we that satisfy weaker property, call firm-covariance , property charac...

Let R be a ring and V be a matrix valuation on R. It is shown that, there exists a correspondence between matrix valuations on R and some special subsets ?(MVPR) of the set of all square matrices over R, analogous to the correspondence between invariant valuation rings and abelian valuation functions on a division ring. Furthermore, based on Malcolmson’s localization, an alternative proof for t...

We study a particular restitution problem where there is an indivisible good (land or property) over which two agents have rights: the dispossessed agent and the owner. A third party, possibly the government, seeks to resolve the situation by assigning rights to one and compensate the other. There is also a maximum amount of money available for the compensation. We characterize a family of asym...
