Price Destabilizing Speculation
The Harvard community has made this article openly available. Please share how this access benefits you. Your story matters. It is sometimes asserted that rational speculative activity must result in more stable prices because speculators buy when prices are low and sell when they are high. This is incorrect.

متن کاملMarket Turmoil and Destabilizing Speculation
This paper explores how speculators can destabilize financial markets by amplifying negative shocks in periods of market turmoil, and confirms the main predictions of the theoretical analysis using data on money market funds (MMFs). I propose a dynamic trading model with two types of investors —long-term and speculative —who interact in a market with search frictions. During periods of turmoil ...
متن کاملSpeculation in First-Price Auctions with Resale
We analyze first-price auctions with two asymmetric bidders, where the winner can offer the good for resale to the loser. One bidder has a private value for the good, the other bidder—the speculator—has zero value. We show that, independently of the resale market rules, the speculator’s expected profit equals zero. Nevertheless, the opportunity for resale can create a role for an active specula...
متن کاملThe Simple Economics of Commodity Price Speculation
The price of crude oil in the U.S. never exceeded $40 per barrel until mid-2004. By 2006 it reached $70, and in July 2008 it peaked at $145.

We clarify the effects of speculators on commodity prices. We focus on crude oil, but our approach can be ...
متن کاملSpeculation in Second-Price Auctions with Resale
This paper contributes to the literature on second-price auctions with resale. We add speculators—bidders with value zero—to the standard symmetric independent private values environment. There always exists a continuum of inefficient equilibria that are profitable for a speculator. With no reserve price in the initial auction, speculation can enhance the initial seller’s expected revenue. On t...
