This paper provides an overview of global solid waste generation, its environmental costs, and fiscal instruments that can be used to encourage waste reduction and finance proper disposal. Countries—especially island nations--struggle to manage an ever-increasing volume of solid waste, generation of which is projected to exceed 2 billion tons a year by 2025. Although solid waste management is usually relegated to subnational governments, externalities from inadequate management, which include greenhouse gas emissions and ocean plastic pollution, reach global scale. National governments thus play a critical role in creating incentives for waste minimization and ensuring adequate resources for proper waste management. This paper evaluates potential fiscal instruments to achieve these goals, particularly in developing country policy environments.
In reaction to the recent financial crisis, increased attention has recently been given to financial transaction taxes (FTTs) as a means of (1) raising revenue for a variety of possible purposes and/or (2) helping to curb financial market excesses. This paper reviews existing theory and evidence on the efficacy of an FTT in fulfilling those tasks, on its potential impact, and on key issues to be faced in designing taxes of this kind.
This paper examines the main distortions of the U.S. corporate income tax (CIT), focusing on its international aspects, and proposes a set of reforms to alleviate them. A bold reform to replace the CIT with a corporate-level rent tax could induce efficiency-enhancing reform of the international tax system. Since fundamental reform is politically difficult, this paper also proposes an incremental reform that would reduce tax expenditures, reduce the CIT rate to 25-28 percent, and impose a minimum rent tax on foreign earnings. Finally, this paper analyzes empirically the likely impact of the incremental on corporate revenues outside the U.S.: Though a U.S. rate cut would likely lower revenues elsewhere, implementation of a strong minimum tax could more than offset that effect for most countries with effective tax rates above 15 percent.
In contrast to most Scandinavian countries, Iceland allocates the income of closely held businesses (CHBs) between capital and labor based on administratively set minimum wages rather than an imputed return to book assets. This paper contrasts the relative tax burdens of the current minimum wage system with asset-based allocation methods, and finds that switching to an asset-based method could increase tax revenues from CHBs in a generally progressive manner. Predictably, the shift would also raise the tax burden of skilled labor-intensive industries more than it would that of capital-intensive industries.
This paper suggests that the environmental and commercial features of shale gas extraction do not warrant a significantly different fiscal regime than recommended for conventional gas. Fiscal policies may have a role in addressing some environmental risks (e.g., greenhouse gases, scarce water, local air pollution) though in some cases their net benefits may be modest. Simulation analyses suggest, moreover, that special fiscal regimes are generally less important than other factors in determining shale gas investments (hence there appears little need for them), yet they forego significant revenues.
This paper describes, and where possible tentatively quantifies, likely tax spillovers from the U.S. corporate income tax reform that was part of the broader 2017 tax reform. It calculates effective tax rates under various assumptions, showing among other findings, how the interest limitation and the Foreign Derived Intangible Income provision can raise or reduce rates. It tentatively estimates that under constant policies elsewhere, the rate cut will reduce tax revenue from multinationals in other countries by on average 1.6 to 5.2 percent. If other countries react in line with historical reaction functions, the revenue loss from multinationals rises to an average of 4.5 to 13.5 percent. The paper also discusses profit-shifting, real location, and policy reactions from the more complex features of the reform.
Developing countries apply numerous sector-specific taxes to telecommunications, whose buoyant revenues and formal enterprises provide a convenient “tax handle”. This paper explores whether there is an economic rationale for sector-specific taxes on telecommunications and, if so, what form they should take to balance the competing goals of promoting connectivity and mobilizing revenues. A survey of the literature finds that limited telecoms competition likely creates rents that could efficiently be taxed. We propose a “pecking order” of sector-specific taxes that could be levied in addition to standard income and value-added taxes, based on capturing rents and minimizing distortions. Taxes that target possible economic rents or profits are preferable, but their administrative challenges may necessitate reliance on service excises at the cost of higher consumer prices and lower connectivity. Taxes on capital inputs and consumer access, which distort production and restrict network access, should be avoided; so should tax incentives, which are not needed to attract foreign capital to tap a local market.
This paper discusses key findings and recommendations of the Technical Assistance Report on Optimal Reform and Distributional Analysis of the Personal Income Tax (PIT). With regard to reforming the PIT schedule, it recommends that the basic credit be increased and made fully refundable to all taxpayers age 18 and older. To avoid paying this benefit to young singles, such as students, who generally have other means of support, it could be conditioned on a certain level of labor earnings. This credit should be rapidly phased out as labor income rises, and the initial PIT rate should be significantly reduced. The current top PIT rate does not need reform, although the threshold for that rate should ideally be raised.
This study focused on environmental tax measures, and on allocation, pricing, and taxation of Iceland’s major hydropower and geothermal resources. Measures to secure the tax base for the corporate income tax (CIT) are proposed. Taxation of the financial sector can be improved by a number of measures. The measures that increase fiscal levies on energy-intensive industries should be avoided. The proposals in this paper aim at efficiency and equity in the tax system rather than revenue growth.
