Influencing Lenders’ Repeat Investment Intention in P2P Lending Platforms in China through Signaling
Repeated investments by lenders are critical for the survival and success of an online P2P lending platform. Lenders’ trust in a platform influences their investment decisions. This study explores the impact of trust and its antecedents on lender investment intention in online P2P lending platforms. An online survey of 358 active P2P lenders on several leading online P2P lending platforms in China was conducted. Empirical results suggest that lender trust in a platform has a strong influence upon both perceived risk and investment intention. Furthermore, the results show that top management team heterogeneity, reputation, and quality of the platform have significant effects on lender trust. Both theoretical and practical implications of these findings are discussed
Hierarchical triple mergers: testing Hawking's area theorem with the inspiral signals
Hawking's area theorem is one of the fundamental laws of black holes (BHs),
which has been tested at a confidence level of with gravitational
wave (GW) observations by analyzing the inspiral and ringdown portions of GW
signals independently. In this work, we propose to carry out the test in a new
way with the hierarchical triple merger (i.e., two successive BH mergers
occurred sequentially within the observation window of GW detectors), for which
the properties of the progenitor BHs and the remnant BH of the first
coalescence can be reliably inferred from the inspiral portions of the two
mergers. As revealed in our simulation, a test of the BH area law can be
achieved at the significance level of for the hierarchical
triple merger events detected in LIGO/Virgo/KAGRA's O4/O5 runs. If the
hierarchical triple mergers contribute a fraction to the
detected BBHs, a precision test of the BH area law with such systems is
achievable in the near future. Our method also provides an additional criterion
to establish the hierarchical triple merger origin of some candidate events.Comment: 5 pages, 5 figures, 1 tabl
Splitting the Echoes of Black Holes in Einstein-nonlinear Electrodynamic Theories
Black hole echo is an important observable that can help us better understand
gravitational theories. We present that the non-linear electrodynamic black
holes can admit the multi-peak effective potential for the scalar
perturbations, which can give rise to the echoes. After choosing suitable
parameters, the effective potential can exhibit a structure with more than two
peaks. Putting the initial wave packet released outside the peaks, we find that
the time-domain profile of the echo will split when the peaks of the effective
potential change from two to three. This is a phenomenon of black hole echo and
it might be possible to determine the geometric structure of the black hole
according to this phenomenon through gravitational wave detection.Comment: 7 pages, 6 figures, and 1 table; reference added, title change
