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

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

Abstract

Background 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

The theory of optimal currency areas stresses that a single currency zone should have symmetry across shocks and structures. What happens if the monetary transmission mechanisms differ so that a common monetary policy has different effects in different places? Using a fully specified econometric model, we find that such asymmetries are likely to destabilise the business cycle and put countries out of phase with each other in a way that cannot be corrected by deficit-constrained national fiscal policies. Market discipline, however, could achieve this. Hence, the question is whether the markets would create sufficient discipline on their own.  相似文献

This paper analyses the impact of environmental liability regimes on the capital structure of firms. We show that imposing environmental liability only on polluting firms, with limited liability, increases use of bank debt. Extending environmental liability to banks lowers bank borrowing relative to liability only on firms, with an ambiguous effect relative to no liability. Using US industry-level data we estimate a reduced-form model of bank borrowing by firms and show that the introduction of environmental liability only on firms increased bank borrowing by 15–20%, but when liability was extended to banks, borrowing returned to a level slightly higher than with no liability.  相似文献

In questa nota si estendono alcuni precedenti risultati dovuti a Beccacece-Castagnoli [1]–[2] e Levi [7], sulla dominanza temporale, stocastica e stocastico-temporale tra flussi finanziari, certi o aleatori, nel caso discreto e finito. Largo spazio viene anche dato ad esempi critici e controesempi.
Summary This paper extends previous results by Beccacece-Castagnoli [1]–[2] and Levi [7] on time dominance, stochastic dominance, time-stochastic dominance for discrete, finite, deterministic or stochastic, cashflows. Last sections are devoted to critical examples and counterexamples.

The JOBS Act allows certain analysts to be more involved in the IPO process, but does not relax restrictions on analyst compensation structure. We find that these analysts initiate coverage that is more optimistically biased, less accurate, and generates smaller stock market reactions. Investors purchasing shares following these initiations lose over 3% of their investment by the firm's subsequent earnings release. By contrast, issuers, analysts, and investment banks appear to benefit from this increased bias, as optimism is more positively associated with proxies for firm visibility and investment banking revenues when analysts are involved in the IPO process.  相似文献
