The emergence of Industry 4.0 and related technologies are changing companies' business model and it’s supply chains. A digital supply chain (DSC) powered by disruptive technologies (DTs) can help organizations to build a sustainable competitive advantage. Although studies on one or some of the DTs gaining momentum over recent years, the literature on DTs adoption in DSC does not report a sufficient number of studies focusing on individual-level adoption behavior. The current study aims to bridge this research gap by examining the determinants of the successful adoption of DTs in DSCs in the USA. Accordingly, this study developed a conceptual model based on the technology–organization–environment (TOE) framework and diffusion of innovation (DOI) theory. Further, this study tested the hypotheses using the PLS-SEM, a partial least squares structural equation modeling. The results indicated that organizational and technology factors influence adoption decisions. Environmental factors such as competitive pressure also play a significant role in DT adoption, but innovation factors do not have any influence whatsoever. Moreover, this study contributes new knowledge to the body of literature on the antecedents of DTs adoption in DSC."

Godunov type numerical schemes for the class of hyperbolic systems, admitting non-classical shocks are proposed. It is shown that the numerical approximations converge to the solution and preserve the physical properties of the system such as positive density and bounded velocity. The scheme has been extended to positivity preserving and velocity bound preserving second-order accurate scheme by using appropriate slope limiters. The numerical results are compared with the existing the literature and the scheme is shown to capture the solution efficiently. The paper presents a hyperbolic system, for which an entropy satisfying scheme is constructed through an appropriate decoupling of the system into two scalar conservation laws with discontinuous flux.

Positivity--preserving numerical scheme for hyperbolic systems with δ− shock solutions and its convergence analysis

Online shopping is growing fast across the globe and so are its complexities. Fraud is a complicated phenomenon and its mitigation is critical for running a smooth business. The case considered for the present study is fraud mitigation in return – refund process managed by the customer services of an online retail business. Predictive analytics approach was used to identify early indicators of agent refund fraud – a rare event. The technique used to solve the problem was a Penalised Likelihood based Logistic Regression model. The proposed model allowed the business to select top 5% sample of refund transactions with a higher likelihood of fraud as indicated and queue them for an audit. Implementation of this model resulted in an incremental lift in fraud capture rate.

Measure‐valued weak solutions for conservation laws with discontinuous flux are proposed and explicit formulae have been derived. We propose convergent discontinuous flux‐based numerical schemes for the class of hyperbolic systems that admit nonclassical urn:x-wiley:00222526:media:sapm12319:sapm12319-math-0001‐shocks, by extending the theory of discontinuous flux for nonlinear conservation laws to scalar transport equation with a discontinuous coefficient. The article also discusses the concentration phenomenon of solutions along the line of discontinuity, for scalar transport equations with a discontinuous coefficient. The existence of the solutions for transport equation is shown using the vanishing viscosity approach and the asymptotic behavior of the solutions is also established. The performance of the numerical schemes for both scalar conservation laws and systems to capture the urn:x-wiley:00222526:media:sapm12319:sapm12319-math-0002‐shocks effectively is displayed through various numerical experiments.

Given the importance of the relationship between oil and liner shipping markets, this paper examines the volatility spillover and connectedness between oil and liner shipping markets. We employ dynamic conditional equicorrelations and spillover index approach to know volatility co-movement and spillover between oil prices and returns of liner shipping stocks, respectively. The volatility co-movement between oil and liner shipping companies' stock returns increased during the 2007–09 global financial crisis and 2010–12 Eurozone debt crisis. We extend our analysis by considering portfolio diversification strategies and utility gains across pre-crisis, crisis and post-crisis periods. Our findings are useful to policymakers and investors.

In this paper, we employ a unique tax experiment and dataset in a highly salient tax rate environment to examine consumer response to complex and uncertain tax reforms. Tax reforms raise some fundamental questions in public finance: How does consumption respond to tax change? How is the tax burden distributed among the stakeholders? More importantly, are these answers conditional on whether the tax regime (and not the tax rate) is salient? We find that unpredictability of tax policy changes induces imperfectly rational consumption response. The tax regime complexity does not allow clear tracing of price change despite full information about tax rate changes and so, consumers also respond to notional price changes. This notional response is based on inaccurate beliefs about the impact of visible tax changes on real commodity prices and thus, consumers hoard even those goods that experience a price fall post reform. We further analyse commodity pricing to see how businesses respond and provide evidence of skewness in pricing response post the reform. The burden of tax increase is passed through more than the benefit of tax decrease. Both these aspects, irrational hoarding and an asymmetric transfer of tax benefit to final consumers, are welfare reducing. This is important from a policy perspective since it highlights issues created by complex tax policies.

(Ir)Rational Consumer Responses: Effect of Uncertain Tax Changes

Stochastic modelling of fatigue (and other material's deterioration), as well as of cumulative damage in risk theory, are often based on compound sums of independent random variables, where the number of addends is represented by an independent counting process. We consider here a cumulative model where, instead of a renewal process (as in the Poisson case), a linear birth (or Yule) process is used. This corresponds to the assumption that the frequency of “damage” increments accelerates according to the increasing number of “damages”. We start from the partial differential equation satisfied by its transition density, in the case of exponentially distributed addends, and then we generalize it by introducing a space derivative of convolution type (i.e., defined in terms of the Laplace exponent of a subordinator). Then we are concerned with the solution of integro‐differential equations, under proper initial conditions, which, in a special case, reduce to a fractional one. Correspondingly, we analyze the related cumulative jump processes under a general infinitely divisible distribution of the (positive) jumps. Some special cases (such as the stable, tempered stable, gamma, and Poisson) are presented.

This article is a pioneer work that examines the mediating role of quality management (QM) capability on the relationship between dynamic capability and new product development (NPD) performance in the electronics sector. Dynamic capabilities help a firm sustain its competitiveness in the changing environment, and the electronics industry is chosen as the setting for the research, considering the high level of dynamism in terms of customer preferences, competition, and technology. The proposed model is validated through an empirical study among 123 NPD units in the electronics manufacturing sector. NPD performance is analyzed employing structural equation modeling on the competitive performance, customer satisfaction, development cost and development time. The results of the analysis support the hypothesis that the dynamic capabilities affect the NPD performance along all the dimensions except development cost and QM capability mediates on these relations. The findings can be used by the decision-makers worldwide and across industries to achieve enhanced NPD performance.

This study uses patent renewal information to estimate the private value of patents. Patent value refers to the economic reward that the inventor extracts from commercialising the patented invention. Our empirical analysis comprises 555 patents with applications filed between 1999 and 2002. The term of these patents either ended in 2018 or lapsed due to non-payment of the renewal fee. We model the renewal decision of patentee as ordered probit where patent renewal fee increases with the age of the patent. Variables, such as patent family size, technological scope, number of inventors and grant lag, are used as explanatory variables in the corresponding regression. Hence, this paper combines the patentee's renewal decision along with patents' characteristics and renewal cost schedule to estimate the initial rent distribution. We find that a large number of patents expire at an early stage leaving few patents with high value corroborating the results of studies using European, American and Chinese data. As expected, patents from certain technology class enjoy high valuation.

The work identifies and ranks the competencies that positively influence the customer services and thereby is helpful in customer satisfaction.  The study is conducted in a cooperative bank in one of the districts of South India. Identification of the competencies was made after review of the literatures, interviews with the employees, and expert opinion and a consensus was arrived at. Analytic Hierarchy Process is used to rank the competencies.  Five job competencies are identified to be ranked. Three distinct groups of employees are identified, and responses are collected in the scale proposed by Saaty (1980). Normalization of the data is made by computing the geometric mean of the responses.  The ranking reveals that relationship management competency has the top most priority and the teambuilding, and technical competency the least priority in providing the customer service. The major finding of the study is identification of cognitive competency as most important for managers and accountants and the clerical staff requires relationship management competency to achieve customer satisfaction. This finding will be helpful in identifying the training needs of three categories of employees in improving their customer service performance through job competencies.
