The U.S. income tax system has long been recognized as a hybrid of an income and consumption tax system, with elements that do not fit naturally into either pure system. What it actually is has important policy implications for, among other things, understanding the impact of moving closer to a pure consumption tax regime. In this paper, we examine the nature of the U.S. income tax system by calculating the revenue and distributional implications of switching from the current system to one form of consumption tax, a modified cash flow tax. 相似文献

Abstract. This paper contributes to the growing literature that analyses the Spanish publishing performance in Economics throughout
the 1990s. Several bibliometric indicators are used in order to provide Spanish rankings (of both institutions and individual
authors) based on Econlit journals. Further, lists of the ten most influential authors and articles over that period, in terms of citations, are reported.
We are grateful to many colleagues who made very useful remarks to preliminary versions of this paper, as well as to two anonymous
referees. We are particularly indebted to Xavier Sala-i-Martín, without whose invaluable help this work would not have been
possible. All errors or omissions are of our exclusive responsibility. 相似文献

This study presents theoretical arguments and evidence that attempt to show the contribution of economic mechanisms typical
of a business for resolving problems of environmental protection. Firstly, a brief synopsis is given of the classic solutions
that environmental economics proposes for correcting environmental externalities. Next, the benefit of expanding these two
mechanisms is discussed so that they include those intermediate mechanisms for which it is not possible to clearly establish
if they are developed within the domain of the market or the business. The study's focus resides in the fact that the explicit
expansion of the range of solutions proposed from a macroeconomic point of view establishes a connecting point between environmental
economics and business economics, an area in which academic attention to environmental matters has been significantly less.

In this paper empirical evidence is presented on theelasticity of private R & D spending on its price. Acensored panel-data regression model with random effectsis applied to a balanced panel of 726 Italian firms overthe 1992–1997 period. Implied estimates point out thatItalian firms' response to policy measures (including taxcredits), aimed at reducing the user cost of R & D capital,is likely to be substantial (1.50–1.77). Furthermore, wealso find that the elasticity of R & D spending is higherin recession (2.01) than in expansion (0.87). 相似文献

The aim of this paper is to analyze the economic and social cohesion in the European Union. There are different factors to
explain the convergence process and besides, empirical findings are not conclusive. To the European Union, GDP per head interregional
differences have decreased for certain periods but it has remained unchanged or even increased for others periods. The second
report on the economic and social cohesion indicates that some decades are necessary to eliminate regional differences. These
differences in regional GDP are mainly explained by differences in their productive structures, degree of innovate activity,
communications structures, which depend on the relative level of transport infrastructures, and manpower qualifications. This
analysis allows us to obtain some conclusions to the economic policies and the social cohesion.

AbstractBackground and aims: A wide range of treatment options are available for hepatocellular carcinoma (HCC), including systemic treatment with tyrosine kinase inhibitors (TKIs) such as sorafenib and lenvatinib, immunotherapies, locoregional therapies such as selective internal radiation therapy (SIRT) and treatments with curative intent such as resection, radiofrequency ablation and liver transplantation. Given the substantial economic burden associated with HCC treatment, the aim of the present analysis was to establish the cost of using SIRT with SIR-Spheres yttrium-90 (Y-90) resin microspheres versus TKIs from healthcare payer perspectives in France, Italy, Spain and the United Kingdom (UK).Methods: A cost model was developed to capture the costs of initial systemic treatment with sorafenib (95%) or lenvatinib (5%) versus SIRT in patients with HCC in Barcelona Clinic Liver Cancer (BCLC) stages B and C. A nested Markov model was utilized to model transitions between progression-free survival (PFS), progression and death, in addition to transitions between subsequent treatment lines. Cost and resource use data were identified from published sources in each of the four countries.Results: Relative to TKIs, SIRT with SIR-Spheres Y-90 resin microspheres were found to be cost saving in all four country settings, with the additional costs of the microspheres and the SIRT procedure being more than offset by reductions in drug and drug administration costs, and treatment of adverse events. Across the four country settings, total cost savings with SIR-Spheres Y-90 resin microspheres fell within the range 5.4–24.9% and SIRT resulted in more patients ultimately receiving treatments with curative intent (4.6 vs. 1.4% of eligible patients).Conclusion: SIR-Spheres Y-90 resin microspheres resulted in cost savings relative to TKIs in the treatment of unresectable HCC in all four country settings, while increasing the proportion of patients who become eligible for treatments with curative intent. 相似文献

In this paper we suggest that the dual role played by the IMF, as a creditor and as a monitor of economic reforms, might explain the lack of credibility of the Fund threat of sanctioning non-compliance with conditionality. Specifically, we show that the IMF's desire to preserve its reputation as a good monitor may distort its lending decisions towards some laxity. Moreover, such distortionary incentives may be exacerbated by the length of the relationship between a country and the Fund. Estimating a dynamic panel of 53 middle-income countries, for the period 1982–2001, we find that a longer relationship does increase IMF disbursements. 相似文献

We examine the asymptotic behavior of two strategyproof mechanisms discussed by Moulin for public goods – the conservative equal costs rule (CER) and the serial cost sharing rule (SCSR) – and compare their performance to that of the pivotal mechanism (PM) from the Clarke–Groves family. Allowing the individuals’ valuations for an excludable public project to be random variables, we show under very general assumptions that expected welfare loss generated by the CER, as the size of the population increases, becomes arbitrarily large. However, all moments of the SCSR’s random welfare loss asymptotically converge to zero. The PM does better than the SCSR, with its welfare loss converging even more rapidly to zero. 相似文献
