Our experiments investigate the extent to which traders learn from price, differentiating between situations where orders are submitted before versus after price has realized. In simultaneous markets with bids that conditional on neglect information conveyed by hypothetical value of price. sequential is known prior bid submission, react an roughly consistent benchmark theory. The difference’s r...

آلیاژهای منیزیم معمولاً دارای عدم تقارن تسلیم در حالت کشش و فشار هستند که این عامل ناشی از سازوکارهای مختلف تغییر شکل پلاستیک فعال تحت بارگذاری‌های کششی فشاری است. مقاله بر روی شبیه‌سازی المان حجمی نماینده‌ی سه‌بعدی آلیاژ اکسترود شده تمرکز دارد تا با کمک روابط کریستال پلاستیسیته تأثیر شدت بافت پایه ـ را بررسی کند. پلاستیسته مبتنی‌بر لغزش به‌صورت یک زیربرنامه نرم‌افزار آباکوس (U‌M‌A‌T) برای آزمون...

In an asset-pricing model, risk-averse agents need to forecast the conditional variance of a stock’s return. A near-rational restricted perceptions equilibrium exists in which agents believe prices follow a random walk with a conditional variance that is self-fulfilling. When agents estimate risk in realtime, recurrent bubbles and crashes can arise. These effects are stronger when agents allow ...
