Very recently Günther et al. [E. Günther, O. Maurer, N. Megow and A. Wiese (2013). A new approach to online scheduling: Approximating the optimal competitive ratio. In Proc. 24th Annual ACM-SIAM Symp. Discrete Algorithms (SODA).] initiate a new systematic way of studying online problems by...

China's economic growth rates since reforms were introduced in 1979 have been impressive. In the past six years, for example, China's annual average growth rate was 9%. In the real estate sector, investment revenues increased by an average of 27% in each year. However, a recent People's Bank of...

We propose a novel measure for workers' financial incentives based on withinestablishment wage differences among similar workers from the same occupation. This measure captures all forms of incentive pay that lead to workeremployer-specific pay premiums, including explicit (e.g., bonuses) and...

We consider a natural generalization of classical scheduling problems to a setting in which using a time unit for processing a job causes some time-dependent cost, the time-of-use tariff, which must be paid in addition to the standard scheduling cost. We focus on preemptive single-machine...

In this paper, we first discuss the space frame of multidimensional dynamic credit evaluation (MDCE) theoretically, and then propose the conception of identical credit status and pseudo-identical credit status. Taking advantage of space conformational analysis and optimization techniques, a...

Using the turnover decomposition model, we extract unexpected trading volume from trading activity to measure divergence in investors' opinions and explore the explanatory power of that divergence on stock returns. Portfolios built according to the magnitude of opinion divergence are...
