ICMS ecológico como suporte ao Pagamento por Serviços Ambientais (PSA): uma análise para o Estado do Pará

O artigo discute a implantação do ICMS Ecológico no Estado do Pará como suporte ao financiamento de Pagamento por Serviços Ambientais (PSA). Reflete sobre a possibilidade de repasse de parte desses recursos às comunidades locais, em especial às comunidades residentes em Unidades de Conservação. Assume que essas comunidades produzem benefício público ao contribuírem para a conservação dos recursos naturais. O artigo conclui que o ICMS Ecológico é um importante instrumento econômico de financiamento de PSA no Pará. Entretanto, apresenta limitações, dificuldades e desafios. Dentre estes, está há necessidade de conciliar a implementação do ICMS Ecológico com políticas públicas que visem à conservação da biodiversidade e suporte ao desenvolvimento dos municípios sob uma nova lógica econômica.

Renúncia fiscal heterônoma de ICMS na exportação no estado do Pará

O presente trabalho faz análise, sob a égide do federalismo, da renúncia fiscal heterônoma do Imposto de Circulação de Mercadorias e Serviços (ICMS) para exportação introduzida pela Lei Federal Complementar n.º 87 de 13 de Setembro de 1996, Lei Kandir, posteriormente posta pela Emenda à Constituição de n.º 42/2003. Aborda aspectos da autonomia federativa dos Estados Membros, detentores da competência tributária de ICMS, e procura esclarecer os conceitos de imunidade e isenção tributária, competência e autonomia para verificar a possibilidade de violação à autonomia dos Estado mediante usurpação de competência tributária, bem como verificar as perdas fiscais decorrentes da referida renúncia fiscal no Estado do Pará.

Load Characterization and Revenue Metering Under Non-Sinusoidal and Asymmetrical Operation

This paper proposes an approach to load characterization and revenue metering, which accounts for the influence of supply deterioration and line impedance. It makes use of the Conservative Power Theory and aims at characterizing the load from the measurements done at the point of common coupling. Despite the inherent limitations of a single-point measurement, the proposed methodology enables evaluation of power terms, which clarify the effects of reactivity, asymmetry and distortion, and attempts to depurate the power consumption accounted to the load from those terms deriving from supply nonidealities.

Revenue Management in Make-To-Order Manufacturing: Case Study of Capacity Control at ThyssenKrupp VDM

While revenue management (RM) is traditionally considered a tool of service operations, RM shows considerable potential for application in manufacturing operations. The typical challenges in make-to-order manufacturing are fixed manufacturing capacities and a great variety in offered products, going along with pronounced fluctuations in demand and profitability. Since Harris and Pinder in the mid-90s, numerous papers have furthered the understanding of RM theory in this environment. Nevertheless, results to be expected from applying the developed methods to a practical industry setting have yet to be reported. To this end, this paper investigates a possible application of RM at ThyssenKrupp VDM, leading to considerable improvements in several areas.

Using Dynamic Programming Decomposition for Revenue Management with Opaque Products

Opaque products enable service providers to hide specific characteristics of their service fulfillment from the customer until after purchase. Prominent examples include internet-based service providers selling airline tickets without defining details, such as departure time or operating airline, until the booking has been made. Owing to the resulting flexibility in resource utilization, the traditional revenue management process needs to be modified. In this paper, we extend dynamic programming decomposition techniques widely used for traditional revenue management to develop an intuitive capacity control approach that allows for the incorporation of opaque products. In a simulation study, we show that the developed approach significantly outperforms other well-known capacity control approaches adapted to the opaque product setting. Based on the approach, we also provide computational examples of how the share of opaque products as well as the degree of opacity can influence the results.

Costly Revenue-Raising and the Case for Favoring Import-Competing Industries

A standard finding in the political economy of trade policy literature is that we should expect export-oriented industries to attract more assistance than import-competing industries. In reality, however, trade policy is heavily biased toward supporting import industries. This paper shows within a standard protection for sale framework, how the costliness of raising revenue via taxation makes trade subsidies less desirable and trade taxes more desirable. The model is then estimated and its predictions tested using U.S. tariff data. An empirical estimate of the costliness of revenue-raising is also obtained.

Asymmetric Information, Tax Evasion and Alternative Instruments of Government Revenue

Using a pure-exchange overlapping generations model, characterized with tax evasion and information asymmetry between the government (the social planner) and the financial intermediaries, we try and seek for the optimal tax and seigniorage plans, derived from the welfare maximizing objective of the social planner. We show that irrespective of whether the economy is characterized by tax evasion, or asymmetric information, a benevolent social planner, maximizing welfare and simultaneously financing the budget constraint, should optimally rely on explicit rather than implicit taxation.

An analysis of the revenue policy -making process of the Texas Legislature

The purpose of this dissertation was to develop a conceptual framework which can be used to account for policy decisions made by the House Ways and Means Committee (HW&MC) of the Texas House of Representatives. This analysis will examine the actions of the committee over a ten-year period with the goal of explaining and predicting the success of failure of certain efforts to raise revenue.^ The basis framework for modelling the revenue decision-making process includes three major components--the decision alternatives, the external factors and two competing contingency theories. The decision alternatives encompass the particular options available to increase tax revenue. The options were classified as non-innovative or innovative. The non-innovative options included the sales, franchise, property and severance taxes. The innovative options were principally the personal and corporate income taxes.^ The external factors included political and economic constraints that affected the actions of the HW&MC. Several key political constraints on committee decision-making were addressed--including public attitudes, interest groups, political party strength and tradition and precedents. The economic constraints that affected revenue decisions included court mandates, federal mandates and the fiscal condition of the nation and the state.^ The third component of the revenue decision-making framework included two alternative contingency theories. The first alternative theory postulated that the committee structure, including the individual member roles and the overall committee style, resulted in distinctive revenue decisions. This theory will be favored if evidence points to the committee acting autonomously with less concern for the policies of the Speaker of the House. The Speaker assignment theory, postulated that the assignment of committee members shaped or changed the course of committee decision-making. This theory will be favored if there was evidence that the committee was strictly a vehicle for the Speaker to institute his preferred tax policies.^ The ultimate goal of this analysis is to develop an explanation for legislative decision-making about tax policy. This explanation will be based on the linkages across various tax options, political and economic constraints, member roles and committee style and the patterns of committee assignment. ^
