Productive Misallocation and International Transmission of Credit Shocks
International Economic Review, Volume 66, Issue 4, Page 1395-1423, October 2025.ABSTRACT We study the role of international trade in cross‐country financial shock transmission using an equilibrium business cycle model calibrated to the United States and Canada. Heterogeneous firms have differing needs for external finance and face occasionally binding collateral constraints hindering their investments, while input–output linkages ...

New look at secure performance of massive MIMO with low-resolution DACs
ICT Express, 2023 Since the requirement of secure transmission for massive multiple-input–multiple-output (mIMO) is high, we consider a secure massive MIMO system in presence of multiple digital to analog converters (DACs). We deal with complicated performance analysis of

Twenty‐Five Years of Probabilistic Fault Displacement Hazard Assessment
Reviews of Geophysics, Volume 63, Issue 3, September 2025.Abstract Fault displacement hazard poses significant risks to critical infrastructure such as buildings, roads, and pipelines. While some structures can tolerate a certain degree of surface displacement, others, such as buildings, are far more vulnerable. Probabilistic Fault Displacement Hazard Assessment (PFDHA) quantifies the probability of exceeding

On Ergodic Secrecy Capacity for Gaussian MISO Wiretap Channels [PDF]
, 2010 A Gaussian multiple-input single-output (MISO) wiretap channel model is considered, where there exists a transmitter equipped with multiple antennas, a legitimate receiver and an eavesdropper each equipped with a single antenna.

Sequential Monitoring for Changes in GARCH(1,1) Models Without Assuming Stationarity
Journal of Time Series Analysis, Volume 46, Issue 5, Page 981-996, September 2025.ABSTRACT In this article, we develop two families of sequential monitoring procedure to (timely) detect changes in the parameters of a GARCH(1,1) model. Our statistics can be applied irrespective of whether the historical sample is stationary or not, and indeed without previous knowledge of the regime of the observations before and after the break.

RIS-assisted MIMO secure communications with Bob's statistical CSI and without Eve's CSI
Digital Communications and Networks, 2023 In this paper, we consider a reconfigurable intelligent surface (RIS)-assisted multiple-input multiple-output (MIMO) secure communication system, where only legitimate user's (Bob's) statistical channel state information (CSI) can be obtained at the ...

Fading Cognitive Multiple-Access Channels With Confidential Messages
, 2009 The fading cognitive multiple-access channel with confidential messages (CMAC-CM) is investigated, in which two users attempt to transmit common information to a destination and user 1 also has confidential information intended for the destination.

Private Information and Price Regulation in the US Credit Card Market
Econometrica, Volume 93, Issue 4, Page 1371-1410, July 2025.The 2009 CARD Act limited credit card lenders' ability to raise borrowers' interest rates on the basis of new information. Pricing became less responsive to public and private signals of borrowers' risk and demand characteristics, and price dispersion fell by one‐third.

On the Ergodic Secrecy Rate of Massive MIMO Transmission with Partial Legitimate User CSI
2019 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing (PACRIM), 2019 In this paper, we consider the downlink transmission over a single-cell massive multiple-input-multiple-output (MIMO) system in the presence of multiple single-antenna eavesdroppers (massive MIMOME). We concentrate on the practical scenario where partial channel state information (CSI) of legitimate users and no CSI of eavesdroppers are available at ...
