substantial cross-sectional variation in the speed of price of price discovery when measured in “real time.” This heterogeneity …, however, essentially disappears when measured in “trade time.” Consistent with previous work work, I find that trade time is … the hypothesis of Kyle and Obizhaeva (2016b) that “information flows take place in the same business time as trading.” …

This paper investigates the effectiveness of time-dependent data in improving the quality of AI-based products and … services. Time-dependency means that data loses its relevance to problems over time. This loss causes deterioration in the … algorithm's performance and, thereby, a decline in created business value. We model time-dependency as a shift in the …

We study preferences over lotteries that pay a xed prize at an uncertain future date: what we call time lotteries. The … standard model of risk and time preferences, Expected Discounted Utility, implies that individuals must be risk seeking towards … contributions are theoretical. First, we show that risk aversion over time lotteries can be captured by a generalization of Expected …

We employ the convex time budget approach in a laboratory experiment to measure individual discount rates for time … discounting in favor of constant discount rates and because of the long time horizon, the average discount rate of 1.9% is much …

The notion that time is relative has been widely accepted by physicists since Albert Einstein formulated his theory of … theory, the time value of money concept. I show that, to avoid arbitrage, relativistic time concepts call for an adjustment … relativistic time concepts. In this paper, I show how a relativistic approach towards time influences the core principle of finance …

identify exogenous determinants of timing. We develop a theory illustrating conditions under which synchronicity will vary and … identify three factors -- the amount of daylight, the timing of television programming, and differences in time zones -- that … can alter timing. Using the American Time Use Survey for 2003 and 2004, we first show that an exogenous shock to time in …
