最近這陣子 閒來沒啥事 跟同學在學校的資料庫中看一些paper的摘要 其中看到一篇的結尾部分覺得怪怪的,如下: We consider a price adjustment process in a model of monopolistic competition . Firms have incomplete information about the demand structure. When they set a price they observe the amount they can sell at that price and they observe the slope of the true demand curve at that price. With this information they estimate a linear demand curve. Given this estimate of the demand curve they set a new optimal price. We investigate the dynamical properties of this learning process. We find that, if the cross-price effects and the curvature of the demand curve are small, prices converge to the Bertrand-Nash equilibrium. The global dynamics of this adjustment process are analyzed by ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ numerical simulations. By means of computational techniques and by applying ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ results from homoclinic bifurcation theory we provide evidence for the ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ existence of strange attractors. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 奇怪的吸引因子?? 就是上面劃線的部分覺得頗難懂的,跟同學兩人討論來討論去的,不由自主地搞笑起來~XD (雖然前面的部分也沒全然很了解,但最起碼前面部分的文字"看"得懂~:p) 不知有沒有人看的懂這段文字,能幫忙解惑一下的~thx!! -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.119.147.46
