Technological adoption in health care - The role of payment systems

This paper examines the incentive to adopt a new technology given by some popular reimbursement systems, namely cost reimbursement and DRG reimbursement. Adoption is based on a cost-benefit criterion. We find that retrospective payment systems require a large enough patient benefit to yield adoption, while under DRG, adoption may arise in the absence of patients benefits when the differential reimbursement for the old vs. new technology is large enough. Also, cost reimbursement leads to higher adoption under some conditions on the differential reimbursement levels and patient benefits. In policy terms, cost reimbursement system may be more effective than a DRG payment system. This gives a new dimension to the discussion of prospective vs. retrospective payment systems of the last decades centered on the debate of quality vs. cost containment.

Technological adoption in health care

This paper addresses the impact of payment systems on the rate of technology adoption. We present a model where technological shift is driven by demand uncertainty, increased patients’ benefit, financial variables, and the reimbursement system to providers. Two payment systems are studied: cost reimbursement and (two variants of) DRG. According to the system considered, adoption occurs either when patients’ benefits are large enough or when the differential reimbursement across technologies offsets the cost of adoption. Cost reimbursement leads to higher adoption of the new technology if the rate of reimbursement is high relative to the margin of new vs. old technology reimbursement under DRG. Having larger patient benefits favors more adoption under the cost reimbursement payment system, provided that adoption occurs initially under both payment systems.

E-Health individual adoption - empirical model based on UTAUT 2.

The future of health care delivery is becoming more citizen-centred, as today’s user is more active, better informed and more demanding. The European Commission is promoting online health services and, therefore, member states will need to boost deployment and use of online services. This makes e-health adoption an important field to be studied and understood. This study applied the extended unified theory of acceptance and usage technology (UTAUT2) to explain patients’ individual adoption of e-health. An online questionnaire was administrated Portugal using mostly the same instrument used in UTAUT2 adapted to e-health context. We collected 386 valid answers. Performance expectancy, effort expectancy, social influence, and habit had the most significant explanatory power over behavioural intention and habit and behavioural intention over technology use. The model explained 52% of the variance in behavioural intention and 32% of the variance in technology use. Our research helps to understand the desired technology characteristics of ehealth. By testing an information technology acceptance model, we are able to determine what is more valued by patients when it comes to deciding whether to adopt e-health systems or not.

electronic payments in mozambique: A Baseline on their adoption in Maputo and Matola

This study analyses the access and use of financial services by small business owners in the cities of Mozambique, as an important tool for boosting economic growth and diminishing inequality. It correlates owners’ and business characteristics with the probability of adopting Points-of-Sale (POS), Mobile Banking and Mobile Money in everyday transactions. The main findings highlight that what mostly affects the use of POS is the size of business and the volume of transactions (positively correlated with POS adoption), while using mobile phone technologies for payments predominantly depends on the owner’s age and whether he/she is a frequent cellphone user. Moreover, to increase the use of electronic means of payment it is necessary to increase financial literacy and improve the banking services.

Process virtualization theory (PVT) and institutional theory (INT) to explain SAAS adoption

Software as a service (SaaS) is a service model in which the applications are accessible from various client devices through internet. Several studies report possible factors driving the adoption of SaaS but none have considered the perception of the SaaS features and the pressures existing in the organization’s environment. We propose an integrated research model that combines the process virtualization theory (PVT) and the institutional theory (INT). PVT seeks to explain whether SaaS processes are suitable for migration into virtual environments via an information technology-based mechanism. INT seeks to explain the effects of the institutionalized environment on the structure and actions of the organization. The research makes three contributions. First, it addresses a gap in the SaaS adoption literature by studying the internal perception of the technical features of SaaS and external coercive, normative, and mimetic pressures faced by an organization. Second, it empirically tests many of the propositions of PVT and INT in the SaaS context, thereby helping to determine how the theory operates in practice. Third, the integration of PVT and INT contributes to the information system (IS) discipline, deepening the applicability and strengths of these theories.

Enterprise risk management adoption: An empirical investigation of its effects on firm performance

Enterprise Risk Management (ERM) is gaining relevance among financial and non-financial companies but its benefits still are uncertain. This paper aims at investigating the relationship between ERM adoption and firm performance based on a sample of 1130 non-financial companies belonging to the STOXX® index. A content analysis of individual accounts is performed to distinguish adopters, and a regression analysis explores the effect of ERM adoption on firm performance, proxied by Tobin’s Q. The findings suggest that there is a statistical significant positive effect of ERM adoption on firm performance, meaning that firms are benefiting from the implementation of this process.

Contabilidade e relato dos intangíveis: Análise das empresas cotadas na BM&FBOVESPA

O presente trabalho de investigação avalia a situação atual relativa à adoção do disposto na IAS 38 e suas consequências no reconhecimento, mensuração e divulgação obrigatória, e à divulgação voluntária, interna e externa, dos intangíveis nas empresas brasileiras cotadas na BM&FBOVESPA. Adotando a perspectiva positivista e uma abordagem quantitativa, foi utilizado o inquérito por questionário como método de recolha de dados. O questionário foi elaborado de raiz, suportado pelo arcabouço teórico. Os resultados são interpretados à luz dos argumentos da teoria dos stakeholders e da teoria institucional, que revelaram um bom potencial explicativo para o fenômeno em análise. Com a adoção das IAS/IFRS para elaboração dos balanços consolidados de empresas cotadas e não cotadas, o Brasil passa a utilizar a IAS 38, para o registro das operações envolvendo os ativos intangíveis, obrigatoriamente no exercício de 2010. A adoção deste normativo se deu essencialmente por pressões legais. No entanto, as empresas que adotaram a IAS 38 de forma voluntária validaram as razões apresentadas na literatura. Constatou-se que existe concordância quanto à nova forma de contabilização dos intangíveis prevista, sendo o grau de satisfação relativamente ao tratamento contábil dos ativos intangíveis de acordo com o novo modelo contábil adotado no Brasil (IAS 38 e CPC 04) elevado. Como principais dificuldades no reconhecimento contábil dos ativos intangíveis segundo o normativo em vigor, foram confirmados os problemas evidenciados na literatura, tais como incerteza quanto aos benefícios econômicos futuros e falta de medida com confiabilidade suficiente para o registro das transações. As empresas brasileiras acreditam ser importante que haja uma expansão da divulgação sobre intangíveis, no entanto a divulgação interna e externa está ainda em fase embrionária, não sendo uma prática generalizada. Contudo, os objetivos apresentados na literatura para a divulgação interna e externa de informações sobre intangíveis encontram suporte empírico no estudo desenvolvido. No que diz respeito aos stakeholders, conclui-se que as empresas brasileiras têm grande preocupação em atendê-los quando se trata de divulgação voluntária sobre intangíveis, entendendo que todos eles poderão beneficiar com estas informações.
