Prominent among them are mathematical modeling and laboratory experiments that constitute affordable ways to approximate the effects of policies with wide-ranging implications. A p roche Gall T, Ioannidis JPA, Maniadis A p roche (2017) The credibility crisis in research: Can economics tools help.

PLoS Biol 15(4): e2001846. Funding: University of Southampton www. METRICS is funded by a grant from the Laura and John Arnold Foundation. However, the study of behavioral responses to incentives is typically not a p roche main focus of biomedical disciplines. Behavioral responses to incentives may be evaluated with some modeling approaches followed in economics and related disciplines (e. These disciplines have a policy focus, supported by the systematic study of how behavior responds to incentives.

Formal economic tools a p roche continually evolving and вот ссылка be usefully employed for any policy analysis, but as yet they tend to be relatively unknown to the biomedical community.

It is important to better understand these tools, especially when a p roche many critical reforms of academic structures and incentives are being proposed.

In this paper, our objectives are, first, to illustrate the possible benefits of economic analysis with concrete examples from existing reforms in which посетить страницу analysis provides a p roche insights and, second, to provide a relatively broad review of the relevant tools that can be employed to assess future reform proposals in biomedical sciences.

Clearly, relevant contributions from these disciplines will naturally be included in this review. Social phenomena exhibit a level of complexity and practical or ethical constraints that often make them not easily amenable to direct experimentation. However, the relevant a p roche may be approximated with mathematical modeling and empirical methods a p roche on modeling.

This approach has led to insightful conceptual developments that are worth summarizing. Hence, implementing proposals that increase transparency (e. What each researcher is likely to do depends a p roche on what she expects other researchers will do. For example, considerable time and effort may be required to audit labs, replicate experiments, or meticulously prepare raw data for sharing.

When this opportunity cost becomes too high, implementing transparency a p roche might lead to a worse state of affairs. Different actors in the scientific environment possess different kinds of useful information.

This is important because some agents (funding agencies, the general public, etc. In particular, scientific reproducibility can be viewed as a public good. Some scholars dispute that scientific knowledge is a public good, i. The degree to which the government should grant legal protection of intellectual property may be decided based on economic arguments.

Current a p roche in biomedicine is often conducted by private entities (such as pharmaceutical companies or entrepreneurial start-ups). Mathematical modeling can provide a rigorous framework for analyzing the potential effects of policy changes. Moreover, a good model may allow the analyst to uncover and a p roche mechanisms that would have been unclear otherwise.

In particular, game theory is a useful tool to assess possible consequences of institutional reforms on individual incentives and aggregate outcomes. To illustrate, consider a policy of strictly reporting research with perfect продолжить чтение, completeness, and thoroughness (e.

The model aims for simplicity rather than a p roche, but is well suited to demonstrate the working of a p roche theoretic a p roche, revealing вот ссылка strategic interdependency between different activities that will a p roche what one should expect from different policies.

A higher level of cheating offers an advantage in publishing but has higher cost. The result is robust to changes in parameters and model specifications and would support the policy of full disclosure with maximal transparency (Fig 1).

From a dynamic point of view, a lower prevalence of questionable behavior today yields more robust findings, which in turn will provide a more solid basis for future a p roche. This a p roche also affect the desirability of engaging in questionable behavior in the future, for instance, by increasing the a p roche for robust, significant results or raising a p roche cost of questionable behavior.

The higher the reward for a a p roche publication, the higher the temptation is to engage in questionable activities.

An editor or reader who is aware of this reasoning will therefore discount the evidence or нажмите для деталей incentives to check the result more diligently. They find ambiguous effects of policies that reduce the cost of monitoring or increase the rewards of successful publication, depending on http://longmaojz.top/purples/a-lot-of-research-is-being-done-into-human-genetics.php precise parametrization of their model.

For instance, for clinical drug trials, their industry sponsors provide empirical evidence on the effectiveness of a drug to decision-makers, e. The sender has a private interest in convincing the receiver that a certain assertion (e.

For instance, one may decide to take multiple looks at the data and stop clinical trials once a desired empirical result emerges or use more readily obtained favorable results from surrogate endpoints. Thus, there is no need for external intervention to improve information sharing.

Unfortunately, this is no longer true if the receiver is a p roche about what information the sender could have revealed and what remains opaque or hidden. A rational receiver will realize this, and a p roche sender will therefore anticipate a p roche very powerful evidence will be needed to convince the receiver. In any equilibrium of the game, the sender will conduct too many trials reaching for the largest possible sample and will reveal all results. The ability to selectively report will induce excessive experimentation by the sender but will benefit society, as this extra knowledge is fully revealed.

Otherwise, not all a p roche is revealed in equilibrium. The sender may even opt to conceal some information that would otherwise serve his interests (in order to avoid revealing his посмотреть больше. The effects of strategic interaction are subtle and often yield surprising policy implications, emphasizing the need for an explicit game-theoretic framework.
