In this paper, I review and assess what we have learned about what motivates individuals to pay – or to not pay – their legally due tax liabilities. I focus on three specific questions. First, what does theory say about what motivates tax compliance? Second, what does the evidence show? Third, how can government use these insights to improve compliance? I conclude with some suggestions – and some predictions – for future research. 相似文献

Abstract Experimental economics has grown as a discipline from near non‐existence 50 years ago to a full‐fledged field within economics in the present. Much of experimental economics research involves experimental methods as a tool, applied to problems in other fields of economics. However, some of this research is inward looking, focusing on questions of the methodology of experimental economics. In this note, I briefly discuss two methodological issues in experimental economics that might benefit from meta‐analysis: the pool from which experimental participants are drawn (university undergraduate students versus other populations) and the scale of monetary incentives faced by participants (large, small or hypothetical). 相似文献

Accountability mechanisms are among the most important means with which governments guard and improve the performance of public sector organizations. However, research documents a plethora of accountability-failures. A key issue is: how can public sector accountability become more effective? This paper seeks to answer this question by connecting two largely separated strands of research: public administration research on real-world organizations and experimental research on the effects of different forms of accountability on decision-making. The paper develops the Calibrated Public Accountability-model (CPA-model) from experimental research findings which can be used to investigate how accountability can be calibrated to task requirements of organizations. 相似文献

Using laboratory experiments within a New Keynesian sticky price framework, we study the process of inflation expectation formation. We focus on adaptive learning and rational expectations contrary to the previous literature that mostly studied simple heuristics. Using a test for rational expectations that allows heterogeneity of expectations we find that we cannot reject rationality for about 40% of subjects. More than 20% of subjects are also best described by adaptive learning models, where they behave like econometricians and update their model estimates every period. However, rather than using a single forecasting model, switching between models describes their behavior better. Switching is more likely to occur when experimental economy is in a recession. 相似文献

Behavioral finance inherits the standard research methods in the finance, and it makes outstanding contribution to leading the experimental research into the field of finance. It uses the cognitive science as the method guide to expand its scientific research tools. On one hand, the intelligent development of the cognitive science provides an important and effective means of a tool for the behavioral finance research; on the other hand, precisely because behavioral finance theories of progress makes a certain extent, dependent on the modem cognitive science research results and thus the development of cognitive science, its results application and limitation will be confined to a direct impact on the development of behavioral finance. That is why we need an in-depth study of the new method of behavioral finance research and grasps their limitations. 相似文献

We establish the inferential properties of the mean-difference estimator for the average treatment effect in randomised experiments where each unit in a population is randomised to one of two treatments and then units within treatment groups are randomly sampled. The properties of this estimator are well understood in the experimental design scenario where first units are randomly sampled and then treatment is randomly assigned but not for the aforementioned scenario where the sampling and treatment assignment stages are reversed. We find that the inferential properties of the mean-difference estimator under this experimental design scenario are identical to those under the more common sample-first-randomise-second design. This finding will bring some clarifications about sampling-based randomised designs for causal inference, particularly for settings where there is a finite super-population. Finally, we explore to what extent pre-treatment measurements can be used to improve upon the mean-difference estimator for this randomise-first-sample-second design. Unfortunately, we find that pre-treatment measurements are often unhelpful in improving the precision of average treatment effect estimators under this design, unless a large number of pre-treatment measurements that are highly associative with the post-treatment measurements can be obtained. We confirm these results using a simulation study based on a real experiment in nanomaterials. 相似文献

An experimental study was conducted to measure the impact of “herding behaviour” inside a board of directors based on the González (2002 PhD dissertation) theoretical model, which maintains that in a board meeting composed of a CEO and two external directors (A and B), where voting is sequential (CEO → A → B) and the directors’ reputations are valuable, director B tends to copy director A’s decision. Based on the observations made through the experiment, we confirm the presence of herding behaviour. 相似文献

Abstract. Economists devote considerable energies towards refining their econometric techniques to overcome difficulties connected with conducting empirical research. Despite advances in technique. it is not clear whether further refinement in this direction is worthwhile for policy purposes. It may be that no further amount of statistical adjustment of inadequate data will increase understanding, and that better data is simply necessary to add to our knowledge. But rarely is sufficient credit paid to new forms of data. In short, econometric technique is emphasized to the neglect of data innovation, as if new data were merely lying about waiting for an ingenious suggestion for use. This paper surveys advances of the last twenty five years in estimating labour supply for policy purposes with a view towards appreciating the relative contribution of both improvements in econometric technique as well as developments of new data.
After briefly detailing the key parameters which economists have sought to estimate, we describe the early 'first generation' research (circa 1970), which is plagued by problems of unobservable variables, measurement errors, truncation and selectivity bias, and non linear budget constraints. 'Second generation' research constitute attempts to resolve one or more of these difficulties, and the respective contribution of econometric technique and new data is acknowledged and assessed, including the contribution of data generated by large scale social experiments in which participants are randomly assigned to different guaranteed income plans and their labour supply behaviour measured. 相似文献

This paper outlines the purposes of audit judgment and decision making (audit JDM) research and explains the basic principles of experiments and experimental designs. Choices of dependent and independent variables are discussed, together with choices of manipulating variables within and between subjects. The use and effectiveness of randomization to control for extraneous variables is discussed together with various internal validity threats that can exist. Finally, four design choices affecting internal validity are addressed. These design issues relate to the use of control groups, manipulation checks, controlled experiments and incentives. Many of the choices raised in this paper are discussed in more detail in subsequent papers in this issue of the journal. 相似文献

With the gradual development of science and technology, more and more countries regard big science research infrastructures (BSRIs) as the top priority in national development. However, the problem of out-of-control investment often occurs in the construction process of BSRIs, which leads to the loss of property and government credibility. Therefore, this paper carries out research on investment monitoring of BSRIs. The price of the contract signed in the process of engineering construction is taken as the investment monitoring point. And the investment monitoring key points are selected considering the monitoring cost. A three - stage index system of investment monitoring key points from the perspective of project life cycle is established. The generalized trapezoidal fuzzy number is used to describe the evaluation information. The entropy method and best-worst method are used to calculate the objective and subjective weights of indexes respectively. PROMETHEE Ⅱ is applied to rank alternative monitoring points. Finally, empirical research is carried out to verify the effectiveness and stability of the model. The comprehensive weights of contract amount, contractor performance, and adjacent contract payment unit investment amount are 28.83%, 18.81% and 15.05% respectively, which are the three most important indicators in the implementation stage. 相似文献

The validity of artificial situations is often questioned, and particularly so the possibility of transfer of findings to the real world. Such questions, or doubts, may stem from a rigid distinction between real and artificial situations or from too strict a notion of representation. This article will argue that `the real world' does not provide unambiguous criteria for representation and that, moreover, many experiments and simulation games do not have to represent `the real world' in any direct way. Both issues are usually treated under the heading of external validity, which means compliance to conventions that dominated thinking about validity over decades. These conventions need to be reconsidered. Quality standards for research must not be rigid, nor should be applied in a way that ignores the characteristics of a particular research project. Fixed notions about validity may prevent a researcher from adapting validation procedures to the circumstances at hand. The article takes issue with a conception of external validity as surface resemblance between artificial and real situations, advocates an active, non-routine approach to validity questions, and encourages individual researchers to develop a line of reasoning on these questions instead of adhering to standards that may not suit their particular research. 相似文献
