摘要:

我現(xiàn)在封閉解決方案價(jià)格，投資組合和信任在一個(gè)模型四種類(lèi)型的投資者交易資產(chǎn)隨著時(shí)間:天真的投資者通過(guò)社交網(wǎng)絡(luò)，學(xué)習(xí)“狂熱者”可能傳播虛假新聞，和理性的短期和長(zhǎng)期投資者。我認(rèn)為,狂熱的和理性的觀點(diǎn)占主導(dǎo)地位隨著時(shí)間的推移，和他們的相對(duì)重要性取決于他們的影響力。證券市場(chǎng)表現(xiàn)出社交網(wǎng)絡(luò)的溢出效應(yīng),影響力大的影響和思想領(lǐng)袖，泡沫，高容量，價(jià)格動(dòng)量，,基本動(dòng)力和逆轉(zhuǎn)。模型啟示了GameStop事件，歷史泡沫，和更廣泛的資產(chǎn)市場(chǎng)。

原文：I present closed-form solutions for prices, portfolios, and beliefs in a model where four types of investors trade assets over time: naive investors who learn via a social network, “fanatics” possibly spreading fake news, and rational short- and long-term investors. I show that fanatic and rational views dominate over time, and their relative importance depends on their following by influencers. Securities markets exhibit social network spillovers, large effects of influencers and thought leaders, bubbles, bursts of high volume, price momentum, fundamental momentum, and reversal. The model sheds new light on the GameStop event, historical bubbles, and asset markets more generally.
