TL;DR: This paper used the Kalman filter to obtain maximum likelihood estimates of a permanent-transitory component model for log spot and forward dollar prices of the pound, the franc, and the yen.
Abstract: SUMMARY Using the Kalman filter, we obtain maximum likelihood estimates of a permanent‐transitory components model for log spot and forward dollar prices of the pound, the franc, and the yen. This simple parametric model is useful in understanding why the forward rate may be an unbiased predictor of the future spot rate even though an increase in the forward premium predicts a dollar appreciation. Our estimates of the expected excess return on short-term dollar-denominated assets are persistent and reasonable in magnitude. They also exhibit sign fluctuations and negative covariance with the estimated expected depreciation. #1997 John Wiley & Sons, Ltd. J. Appl. Econ., 12, 715‐734 (1997)

TL;DR: In this paper, the authors investigated three oligopoly games among the producers and found a continuum of solutions for tacit collusion among producers in the spot market, where the instruments of competition are the supply functions of the producers.

TL;DR: Trace-based simulations show that several adaptive checkpointing schemes can reduce significantly both monetary costs and task completion times of computation on spot instance, and work migration can improve task completion in the midst of failures while maintaining low monetary costs.
Abstract: Recently introduced spot instances in the Amazon Elastic Compute Cloud (EC2) offer low resource costs in exchange for reduced reliability; these instances can be revoked abruptly due to price and demand fluctuations. Mechanisms and tools that deal with the cost-reliability tradeoffs under this schema are of great value for users seeking to lessen their costs while maintaining high reliability. We study how mechanisms, namely, checkpointing and migration, can be used to minimize the cost and volatility of resource provisioning. Based on the real price history of EC2 spot instances, we compare several adaptive checkpointing schemes in terms of monetary costs and improvement of job completion times. We evaluate schemes that apply predictive methods for spot prices. Furthermore, we also study how work migration can improve task completion in the midst of failures while maintaining low monetary costs. Trace-based simulations show that our schemes can reduce significantly both monetary costs and task completion times of computation on spot instance.

TL;DR: In this article, the authors employed a basic stochastic model, a mean-reverting model and a regime switching model to capture the features in the Australian national electricity market (NEM), comprising the interconnected markets of New South Wales, Queensland, South Australia and Victoria.

TL;DR: This article examined the lead-lag relation between intraday spot and futures prices for a stock index where the component stocks are floor traded while the futures contract is screen traded and found that futures prices lead spot prices by nearly 20 min.
