Are credit ratings valuable information? [PDF]
Applied Financial Economics, 2007 Credit ratings are commonly used by lenders to assess the default risk, because every credit is connected with a possible loss. If the probability of a default is above a certain threshold, a credit will not be provided. The purpose of this study is to test whether credit ratings contribute valuable information on the creditworthiness of firms ...

Liquidity, Information, and the Overnight Rate [PDF]
SSRN Electronic Journal, 2004 We model the interbank market for overnight credit with heterogeneous banks and asymmetric information. An unsophisticated bank justntrades to compensate its liquidity imbalance, while a sophisticated bank willnexploit its private information about the liquidity situation in the market.

Exchange rate forecasting with information flow approach
Business: Theory and Practice, 2016 The purpose of this article is to assess exchange rate forecasting possibilities with an information flow approach model. In the model the three types of information flows are distinguished: fundamental analysis information flow through particular ...

Concavity of the mutual information rate for input-restricted memoryless channels at high SNR [PDF]
, 2012 We consider a memoryless channel with an input Markov process supported on a mixing finite-type constraint. We continue the development of asymptotics for the entropy rate of the output hidden Markov chain and deduce that, at high signal-to-noise ratio ...

On Energy–Information Balance in Automatic Control Systems Revisited
Entropy, 2020 We revise and slightly generalize some variational problems related to the “informational approach” in the classical optimization problem for automatic control systems which was popular from 1970–1990.

What determines the information update rate in echolocating bats
Communications Biology, 2023 The rate of sensory update is one of the most important parameters of any sensory system. The acquisition rate of most sensory systems is fixed and has been optimized by evolution to the needs of the animal.

Opportunistic scheduling with limited channel state information: A rate distortion approach [PDF]
, 2014 We consider an opportunistic communication system in which a transmitter selects one of multiple channels over which to schedule a transmission, based on partial knowledge of the network state. We characterize a fundamental limit on the rate that channel

Isogloss, 2022 While languages convey significantly different amounts of both information per syllable and syllables per second, recent research suggests that the product of these values— information conveyed per second—is much less variable.

On Achievable Rate Regions for Source Coding Over Networks [PDF]
, 2009 In the field of source coding over networks, a central goal is to understand the best possible performance for compressing and transmitting dependent data distributed over a network.
