I describe asset price dynamics caused by the slow movement of investment capital to trading opportunities. The pattern of price responses to supply or demand shocks typically involves a sharp reaction to the shock and a subsequent and more extended reversal. The amplitude of the immediate price impact and the pattern of the subsequent recovery can reflect institutional impediments to immediate trade, such as search costs for trading counterparties or time to raise capital by intermediaries. I discuss special impediments to capital formation during the recent financial crisis that caused asset price distortions, which subsided afterward. After presenting examples of price reactions to supply shocks in normal market settings, I offer a simple illustrative model of price dynamics associated with slow-moving capital due to the presence of inattentive investors.I ADDRESS THE IMPLICATIONS for asset price dynamics of the apparent slow movement of investment capital to trading opportunities. The arrival of new capital to an investment opportunity can be delayed by fractions of a second in some markets, for example an electronic limit-order-book market for equities, or by months in other markets, such as that for catastrophe risk insurance. Accordingly, prices respond to supply or demand shocks with a sharp reaction because of the relatively small subset of capital (and thus risk-bearing capacity) that is immediately available to absorb a shock on short notice. Such a price impact is substantially reversed over time as additional capital becomes available. The amplitude of the immediate price impact and the pattern of the subsequent recovery can reflect many sorts of attention costs to trade as well as institutional impediments to capital movement, such as search costs for trading * Darrell
