The Effect of COVID-19 on Cashless Payments

The outbreak of the SARS-CoV-2 coronavirus(COVID-19)has impacted the whole world.To stop the virus’s spread,governments enforced regulations requiring face masks and social isolation and also promoted social seclusion,hand-washing,and other hygienic measures.People’s movements and consumption were significantly reduced as a result of government-imposed lockdowns,with internet purchasing overtaking in-store purchasing in a particularly noticeable way.Most importantly,people’s habits during times of restrictions and lockdowns seemed to reduce overall desire to do cash transactions.Cashless transactions became the most preferred option for daily payment as it helped reduce contact with others and prevent them from becoming infected.These factors contribute to future intentions to eliminate cash payments once the pandemic is ended as well as the choice of payment methods currently in use.Even after the pandemic,people are using digital cashless payments for their daily transactions.This study investigates the impact of the coronavirus on consumer demand for cash and cashless payments during the COVID-19 crisis and beyond.This study utilizes the secondary research method by employing the annual statistical report of European Central Bank(ECB)(2021).The data were extracted from the warehouse of ECB,and rigorous analysis was performed to assess the intentions of customers for using digital transactions for payments.In the study,a regression analysis shows that a greater increase in the number of cards used for payment per year occurred during the COVID-19 pandemic than before the pandemic.The study demonstrates that there was a significant correlation between the adoption of cashless payment systems and the restrictions imposed on consumers because of the pandemic.Customers prefer cashless transactions when there is a higher danger of infection while handling cash.

Impact of cash crop cultivation on household income and migration decisions:Evidence from low-income regions in China

This study examines the impact of cash crop cultivation on household income and migration decisions,using survey data collected from low-income regions in China.Given farmers decide themselves whether to cultivate cash crops,an endogenous treatment regression model that accounts for potential selection bias issue is used to analyze the data.The empirical results show that cash crop cultivation exerts a positive and statistically significant impact on household income,but it does not affect household migration decisions significantly.The disaggregated analyses reveal that cash crop cultivation significantly increases farm income but decreases off-farm income.

CASH SUBADDITIVE RISK MEASURES FOR PORTFOLIO VECTORS

In this paper, from the viewpoint of the time value of money, we study the risk measures for portfolio vectors with discount factor. Cash subadditive risk measures for portfolio vectors are proposed. Representation results are given by two different methods which are convex analysis and enlarging space. Especially, the method of convex analysis make the line of reasoning and the representation result be simpler. Meanwhile, spot and forward risk measures for portfolio vectors are also introduced, and the relationships between them are investigated.

Anomaly Detection of Store Cash Register Data Based on Improved LOF Algorithm

As the cash register system gradually prevailed in shopping malls, detecting the abnormal status of the cash register system has gradually become a hotspot issue. This paper analyzes the transaction data of a shopping mall. When calculating the degree of data difference, the coefficient of variation is used as the attribute weight;the weighted Euclidean distance is used to calculate the degree of difference;and k-means clustering is used to classify different time periods. It applies the LOF algorithm to detect the outlier degree of transaction data at each time period, sets the initial threshold to detect outliers, deletes the outliers, and then performs SAX detection on the data set. If it does not pass the test, then it will gradually expand the outlying domain and repeat the above process to optimize the outlier threshold to improve the sensitivity of detection algorithm and reduce false positives.

Cash holdings,corporate governance,and acquirer returns

Background:The wealth effect of limiting shareholder rights via anti-takeover provisions(ATPs)is a contentious issue.By taking the differential effect hypothesis perspective,our study aims to provide additional evidence about the relation between ATPs and acquisition performance.Methods:We examine the interaction of antitakeover provisions(ATPs)with firm characteristics and governance environment in explaining the cross-section of bidder announcement returns.Using a sample of 3,340 completed acquisitions by 1,217 firms during 1996–2006,we test the association between ATPs,firm characteristics,and governance environments with bidder returns.Results:We find that ATPs hurt acquisition performance only when acquirers hold a high level of excess cash.Similarly,ATPs are associated with lower bidder returns only when industry competition is weak and public pension fund ownership is low as well.By contrast,when industry competition is intense and/or public pension fund ownership is high,ATPs do not hurt bidder returns.Conclusions:The complementarity among ATPs,excess cash,industry competition,and public pension fund ownership suggests that ATPs per se do not necessarily result in value-destroying acquisitions for all firms.We address the endogeneity issue of unknown variables by using a proxy for firm prestige and draw the same conclusions.

Factors affecting consumer acceptance of electronic cash in China:an empirical study

This paper proposes and validates a comprehensive model of consumer acceptance in the context of offline e-cash payment.It modifies the unified theory of acceptance and the use of technology model(UTAUT)with constructs of perceived security,cost of use,and government policy.Data collected from 4428 questionnaires about users’attitudes toward e-cash is used to apply a structural equation model which,in turn,assesses the predictive model.The empirical results indicate that perceived security and cost of use are beneficial extensions to the traditional UTAUT model,and intention is a key antecedent to users’actual utilization of e-cash.In addition,the demographic moderators are found to have significant effects on the relations among the variables.These results are useful to e-cash development and significant to the issue of Digital Currency Electronic Payment.

Alternative measure of financial development and investment-cash flow sensitivity:evidence from an emerging economy

This study examines the impact of financial development on corporate investment in terms of their influence on financing constraints.This study also tries to find the effect of financial development on the investment-cash flow sensitivity across the size,degree of financial constraints and group affiliation of the firm.This study employs dynamic panel data model or more specifically system generalized method of moments(GMM)estimation technique.The estimation results reveal that cash flow affects the investment decision of the company positively,which implies that Indian firms are financially constrained.Also,we observe that financial development reduces the investment-cash flow sensitivity and the effect of financial development is more prominent for small size and standalone firms.The results are robust across the period and,for both financially constrained and unconstrained firms.This study contributes to the existing literature by analyzing the impact of financial development on the role of cash flow in determining investments undertaken by the Indian firms,which is an unexplored issue from an emerging market perspective.

Atomic and efficient e-cash transaction protocol

Atomicity is necessary for reliable and secure electronic commerce transaction and to guarantee the participants' interests. An atomic and efficient e-cash (electronic cash) transaction protocol based on the classical e-cash scheme is presented. The delivery of digital goods is incorporated into the process of payment in the protocol. Apart from ensuring all three levels of atomicity, the novel protocol features high efficiency and practicability with unfavorable strong assumption removed. Furthermore, the proposed protocol provides non-repudiation proofs for any future disputes. At last, analysis of the atomicity and efficiency is illustrated.

Upshot of ohmically dissipated Darcy-Forchheimer slip flow of magnetohydrodynamic Sutterby fluid over radiating linearly stretched surface in view of Cash and Carp method

The present work concerns the momentum and heat transmission of the electro-magnetohydrodynamic (E-MHD) boundary layer Darcy-Forchheimer flow of a Sutterby fluid over a linear stretching sheet with slip. The nonlinear equations for the proposed model are analyzed numerically. Suitable techniques are used to transform the coupled nonlinear partial differential equations (PDEs) conforming to the forced balance law, energy, and concentration equations into a nonlinear coupled system of ordinary differential equations (ODEs). Numerical solutions of the transformed nonlinear system are obtained using a shooting method, improved by the Cash and Carp coefficients. The influence of important physical variables on the velocity, the temperature, the heat flux coefficient, and the skin-friction coefficient is verified and analyzed through graphs and tables. From the comprehensive analysis of the present work, it is concluded that by intensifying the magnitude of the Hartmann number, the momentum distribution decays, whereas the thermal profile of fluid increases. Furthermore, it is also shown that by aug- menting the values of the momentum slip parameter, the velocity profile diminishes. It is found that the Sutterby fluid model shows shear thickening and shear thinning behaviors. The momentum profile shows that the magnitude of velocity for the shear thickening case is dominant as compared with the shear thinning case. It is also demonstrated that the Sutterby fluid model reduces to a Newtonian model by fixing the fluid parameter to zero. In view of the limiting case, it is established that the surface drag in the case of the Sutterby model shows a trifling pattern as compared with the classical case.
