We propose a novel algorithm for sentiment summarization that takes account of informativeness and readability, simultaneously. Our algorithm generates a summary by selecting and ordering sentences taken from multiple review texts according to two scores that represent the informativeness and readability of the sentence order. The informativeness score is defined by the number of sentiment expr...

This paper analyzes the e¤ects of public information in a perfect competition trading model populated by asymmetriclly informed short-horizon investors who have di¤ering private information precisions. We …rst show that information asymmetry reduces price informativess and can lead to multiple linear equilibria, where price informativeness refers to the amount of private information revealed by...

Classical image statistics, such as contrast, entropy, and the correlation between central and nearby pixel intensities, are thought to guide ocular fixation targeting. However, these statistics are not necessarily task relevant and therefore do not provide a complete picture of the relationship between informativeness and ocular targeting. Moreover, it is not known whether either informativene...

We document that firms’ management of accounting earnings increased steadily from 1987 until the passage of the Sarbanes Oxley Act (SOX), with a significant increase during the period prior to SOX, followed by a significant decline after passage of SOX. However, the increase in earnings management preceding SOX was primarily in poorly performing industries. We also show that the informativeness...

The problem addressed in this paper is this: 'the main epistemic problem concerning science ... is the explication of how we compare and evaluate theories '" in the light of the available evidence' (van Fraassen 1983: 27). In other and more mundane words, the question is: what is a good theory, and when is one theory better than another theory, given these data and those background assumptions?...

background: resistive inspiratory muscle training (rimt) is a well-known technique for rehabilitation of patients with chronic obstructive pulmonary disease (copd). incentive spirometry is another technique with potential viability for this application, but there is limited evidence in support of its efficacy in the rehabilitation of copd patients. aim: the objective of this study was to compar...

We consider a model of intermediated trade for a financial asset. Agents' valuation for the asset includes both a private and a common value component. A third party posts a price at which trade can occur, and a buyer and seller simultaneously decide whether to accept or reject the trade. We show that trade can be ex post inefficient, in the sense that a high value seller sells the good to a lo...
