This paper studies the existence of single-price price equilibrium from a given initial distribution of money holdings in a search-theoretic model of money where agents have no time preference. The model is similar to recent models (Green and Zhou [2] and Zhou [5]) of search economies with no constraints on money inventories, except that here money is modeled as indivisible and traders are assu...

background: reduced ovarian reserve has been known to predict poor ovarian response and poor success rates in infertile women undergoing assisted reproductive technology. ovarian reserve also decreases with age but the rate of decline defers from a woman to another. the aim of this study was to detect any difference in ovarian reserve as measured by basal serum fsh and amh between matched cohor...

This paper studies efficient allocation of resources in an economy in which agents are initially heterogeneous with regard to their wealth levels and whether they have ideas or not. An agent with an idea can start a business that generates random returns. Agents have private information about (1) their initial types, (2) how they allocate their resources, and (3) the realized returns. The unobs...

A rm whose net earnings are uncertain, and that is subject to the risk of bankruptcy, must choose between paying dividends and retaining earnings in a liquid reserve. Also, diierent operating strategies imply diierent combinations of expected return and variance. We model the rm's cash reserve as the diierence between the cumulative net earnings and the cumulative dividends. The rst is a diiusi...

Occult primary ovarian insufficiency (also known as incipient ovarian failure or diminished ovarian reserve) is defined as serum AMH level ≤1.1ng/mL in women under age 30. Limited data is available regarding the prevalence of occult POI, the preceding menstrual characteristics and its natural course in otherwise healthy young females. We aimed in this prospective observational study to determin...

OBJECTIVES The purpose of this study was to assess early temporal changes in myocardial perfusion pattern by myocardial contrast echocardiography (MCE) and their relation to myocardial viability in patients with reperfused acute myocardial infarction (AMI). BACKGROUND Myocardial contrast echocardiography no-reflow is associated with poor contractile recovery after AMI. However, little is know...
