Continuous-time random walks are pure-jump processes with several applications in physics, but also in insurance, finance and economics. Based on heuristic considerations, a definition is given for the stochastic integral driven by continuous-time random walks. The martingale properties of the...

The authors examine the effects of a firm’s and its competitors’ online reviews on its demand within the hotel industry. The authors leverage a unique dataset of actual bookings from properties of a major hotel chain in six different markets in the United States, supplemented with online...

This paper provides empirical evidence that emerging market economies adjust capital flow management in response to U.S. monetary policy shocks. Using these shocks as exogenous instruments, we find that such adjustments cause changes to portfolio capital flows — in particular, a one standard...

This paper provides new evidence in support of the idea that bouts of optimism and pessimism drive much of US business cycles. In particular, we begin by using sign-restriction based identification schemes to isolate innovations in optimism or pessimism and we document the extent to which such...
