Firms face many fiscal and labor regulations, but they may evade these legal requirements in several different ways. We develop a model that captures these two types of evasion decisions and unlike existing literature assume firms can evade labor regulations independently from income tax responsibilities. We characterize firms’ entry and evasion behavior and find that the design of the tax system can generate both positive and negative correlations between evasion decisions consistent with what is observed empirically. We then characterize optimal government policies given the firms’ decisions. We obtain intuitive optimal tax rules that highlight the trade‐offs the government faces when firms have multiple margins on which to evade.  相似文献

Abstract

Aims: To evaluate total costs and health consequences of a colorectal cancer (CRC) screening program with colonoscopy, fecal immunochemical tests (FIT), and expanded use of multitarget stool DNA (mt-sDNA) from the perspectives of Integrated Delivery Networks (IDNs) and payers in the United States.

Materials and methods: We developed a budget impact and cost-consequence model that simulates CRC screening for eligible 50- to 75-year-old adults. A status quo scenario and an increased mt-sDNA scenario were modeled. The status quo includes the current screening mix of colonoscopy (83%), FIT (11%), and mt-sDNA (6%) modalities. The increased mt-sDNA scenario increases mt-sDNA utilization to 28% over 10 years. Costs for both the IDN and the payer perspectives incorporated diagnostic and surveillance colonoscopies, adverse events (AEs), and CRC treatment. The IDN perspective included screening program costs, composed of direct nonmedical (e.g. patient navigation) and indirect (e.g. administration) costs. It was assumed that IDNs do not incur the costs for stool-based screening tests or bowel preparation for colonoscopies.

Results: In a population of one million covered lives, the 10-year incremental cost savings incurred by increasing mt-sDNA utilization was $16.2 M for the IDN and $3.3 M for the payer. The incremental savings per-person-per-month were $0.14 and $0.03 for the IDN and payer, respectively. For both perspectives, increased diagnostic colonoscopy costs were offset by reductions in screening colonoscopies, surveillance colonoscopies, and AEs. Extending screening eligibility to 45- to 75-year-olds slightly decreased the overall cost savings.

Limitations: The natural history of CRC was not simulated; however, many of the utilized parameters were extracted from highly vetted natural history models or published literature. Direct nonmedical and indirect costs for CRC screening programs are applied on a per-person-per modality basis, whereas in reality some of these costs may be fixed.

Conclusions: Increased mt-sDNA utilization leads to fewer colonoscopies, less AEs, and lower overall costs for both IDNs and payers, reducing overall screening program costs and increasing the number of cancers detected while maintaining screening adherence rates over 10 years.  相似文献

Merchants and manufacturers are rapidly adopting electronic decision aids to help sell a variety of merchandise. These systems provide product information or recommendations based on input from the consumer and affect the way consumers process information. A conceptual framework, based on information processing theory and three strategic consumer difference variables — goal orientation, autonomy, and expertise — is presented. Based on these differences, propositions are derived to guide design of effective electronic decision aids.
Zusammenfassung Elektronische Entscheidungshilfen: Die Miteinbeziehung der Perspektive des Verbrauchers Händler un Hersteller verwenden in wachsendem Ma\e elektronische Entscheidungshilfen beim Verkauf einer Vielzahl von Waren. Solche Hilfen stellen Produktinformation bereit und liefern Empfehlungen auch aufgrund solcher Dateneingaben, die von der Verbraucherseite kommen, und sie beeinflussen die Art und Weise, wie die Konsumenten Information verarbeiten. Der Beitrag liefert einen begrifflichen Rahmen, der auf der Theorie der Informationsverarbeitung und auf drei Konsumentenvariablen — Zielorientierung, Autonomie und Kompetenz — aufbaut. Auf dieser Grundlage werden Vorschläge für die Gestaltung wirksamer elektronischer Entscheidungshilfen abgeleitet.

The European Child Safety Alliance is an initiative of the European Consumer Safety Association with a network of child injury prevention organizations within 25 Member States in Europe. The Alliance, launched in 2001, focuses on strategies that assist in the reduction of injury related deaths and disability amongst children 0 to 18 years of age in the European Union Members States. The Alliance work is done in partnership with stakeholders from various disciplines involved in child injury prevention in order to promote a coordinated and consistent approach across Europe.  相似文献

This paper investigates adolescent online shopping and self-efficacy development in the virtual setting. The authors present and test a model of antecedents and mediators to two dimensions of online consumer self-efficacy. Additionally, a discriminant analysis finds that more involved adolescent online shoppers can be differentiated from less involved online shoppers on key variables of interest-shopping motivations, self-efficacies, shopping behaviors, and relative influence in household decision-making.  相似文献

We construct new measures of fund style, performance and activity from linear combinations of off‐the‐shelf stock‐market indices. A fund's benchmark portfolio is a linear combination of two or more reference portfolios that in a least‐squares sense most closely approximates the fund's portfolio. The resulting linear combination scalar is itself a measure of fund style and the distance between a fund and its benchmark is a measure of fund activity. Our approach has a number of advantages over existing characteristic‐matching methods. We illustrate our approach using a data set of US institutional funds.  相似文献

The results of an experimental study of retail investors' use of eXtensible Business Reporting Language tagged (interactive) data and PDF format for making investment decisions are reported. The main finding is that data format made no difference to participants' ability to locate and integrate information from statement footnotes to improve investment decisions. Interactive data were perceived by participants as quick and ‘accurate’, but it failed to facilitate the identification of the adjustment needed to make the ratios accurate for comparison. An important implication is that regulators and software designers should work to reduce user reliance on the comparability of ratios generated automatically using interactive data.  相似文献

Little empirical research has been conducted on perceptions of the types of sustainability information dealt with by different managers in internal company processes. In this study the roles of different managers are distinguished based on contingency theory and using the categorisation in the sustainability balanced scorecard concept. Expected sustainability information types are identified for these roles and hypotheses are derived and tested about perceptions of the types of sustainability information in different management roles. Interviews identified 116 roles involved with sustainability information in a set of leading German and UK sustainability reporting companies. Results from analysing sustainability information types contingent upon different management roles contribute to the understanding of sustainability accounting systems and practices and how companies can best support different management roles with appropriate sustainability information.  相似文献
