Several impatient investors with private costs <em>C_i</em> face an indivisible irreversible investment opportunity whose value <em>V</em> is governed by geometric Brownian motion. The first investor <em>i</em> to seize the opportunity receives the entire payoff, <em>V-C_i</em>. We characterize the symmetric Bayesian Nash...

Human subjects decide when to sink a fixed cost C to seize an irreversible investment opportunity whose value V is governed by Brownian motion. The optimal policy is to invest when V first crosses a threshold V* = (1 + w*)C, where the wait option premium w* depends on drift, volatility, and...

This paper analyzes seller choices and outcomes in approximately 700 recent Internet auctions on eBay. The 'Buy it Now' option that is available in these auctions allows the seller to supplement or replace the auction with a posted price offer. We use a structural model to control for the...

This paper analyzes seller characteristics and choices in approximately 1000 eBay auctions for a particular model of PDA. Seller characteristics include frequency of selling, reputation, and the qualities of the product sold. Seller choices include the length of the auction, information provided...

Several investors face an irreversible investment opportunity whose value V is governed by Brownian motion with upward drift and random expiration. The first investor i to seize the opportunity before expiration receives the current V less a privately known cost Ci; the other investors receive...
