I study endogenous learning dynamics for people who misperceive intertemporal correlations in random sequences. Biased agents face an optimal‐stopping problem. They are uncertain about the underlying distribution and learn its parameters from predecessors. Agents stop when early draws “good enough,” so predecessors' experiences contain negative streaks but not positive streaks. When wrongly exp...

In this study, we attempt to explain the home bias puzzle by examining the effect of information quality on the asset allocation decisions taken by agents under the assumption that two types of agents possess different information on the true expected returns of home and foreign assets. Our calibration results based on MSCI data indicate that in order to hedge for the changing quality of the in...

We consider the effect of segregation on opinion formation in social networks with and without influential leaders scale-free random networks, which is found many natural phenomena. have used agent-based modeling simulation, focusing impact model formation. Two simulation scenarios this been considered: (1) original scenario randomly assigns persuasion strengths to agents, (2) a centrality-base...

A series of phenylbipyridinylpyrazoles was synthesized through the reaction of 2-(4-(2-chloropyridin-4-yl)-3-(3-methoxy-5-methylphenyl)-1H-pyrazol-1-yl)acetonitrile (4) with different 6-substituted pyridine-3-ylboronic acids. The final compounds 5a-j were screened at 10 µM against over 60 tumor cell lines at the U.S. National Cancer Institute (NCI). In light of the NCI results, compounds 5c and...

We examine a variety of models in which the variance of a portfolio’s excess return depends on a state variable generated by a first-order Markov process. A model in which the state is known to economic agents is estimated. It suggests that the mean excess return moves inversely with the level of risk. We then estimate a model in which agents are uncertain of the state. The estimates indicate t...

The activity of cefoperazone/sulbactam was compared with eleven other antimicrobial agents against 91 strains of the Bacteroides fragilis group known to be resistant to clindamycin and/or beta-lactam agents. Sulbactam alone possessed moderate activity against most strains and improved the activity of cefoperazone and ampicillin. Bacteroides distasonis strains were more resistant than other spec...

A monopolist sells goods with possibly a characteristic consumers dislike (for instance, he sells random goods to risk averse agents), which does not affect the production costs. We investigate the question whether using undesirable goods is profitable to the seller. We prove that in general this may be the case, depending on the correlation between agents types and aversion. This is due to scr...

We look at two countries that have independent fundamentals, but share the same group of investors. Each country might face a self-fulfilling crisis: Agents withdrawing their investments fearing that others will. A crisis in one country reduces agents’ wealth. This makes them more averse to the strategic risk associated with the unknown behavior of other agents in the second country, increasing...

We study a dynamic mechanism design problem for a network of interdependent strategic agents with coupled dynamics. In contrast to the existing results for static settings, we present a dynamic mechanism that is incentive compatible, individually rational, budget balanced, and social welfare maximizing. We utilize the correlation among agents’ states over time, and determine a set of inference ...

background: solid tumors may occur in 3% of the patients with chronic myeloid leukemia (cml). in this paper, we presented a case of cml following treatment of colon cancer. case presentation: a 25 year old man was diagnosed of adenocarcinoma of rectosigmoid treated with fluorouracil-based chemotherapy. following relapse, he received florouracil, oxaliplatin and irinotecan during the next year. ...
