This paper provides a conceptual overview of economists' attempts to learn about the effects of taxes on extractive resources. The emphasis is on research methods and techniques, with no attempt to provide a comprehensive tabulation of previous empirical results or policy conclusions regarding preferred tax instruments or systems. We argue, in fact, that the nature of such conclusions largely depends on the researcher's choice of modeling framework. Many alternative frameworks and approaches have been developed in the literature. Our goal is to describe the differences among them and to note their strengths and limitations.

In recent years, the IMF has released a growing number of reports and other documents covering economic and financial developments and trends in member countries.

This paper investigates the effect of fiscal transparency on market assessments of sovereign risk, as measured by credit ratings. It measures this effect through a direct channel (uncertainty reduction) and an indirect channel (better fiscal policies and outcomes), and it differentiates between advanced and developing economies. Fiscal transparency is measured by an index based on the IMF's Reports on the Observance of Standards and Codes (ROSCs). We find that fiscal transparency has a positive and significant effect on ratings, but it works through different channels in advanced and developing economies. In advanced economies the indirect effect of transparency through better fiscal outcomes is more significant whereas for developing economies the direct uncertainty-reducing effect is more relevant. Our results suggest that a one standard deviation improvement in fiscal transparency index is associated with a significant increase in credit ratings: by 0.7 and 1 notches in advanced and developing economies respectively.

Does reliance on transfers weaken fiscal discipline and encourage pro-cyclical fiscal policies in recipient subnational governments? Using fiscal reaction functions for a panel of the German Länder, this paper finds a positive answer to both questions. Net-recipient states (Länder, benefiting from the transfer system) have not reduced primary expenditure significantly in response to rising deficits, but have instead relied on vertical transfers from the federal government to ensure debt sustainability. Moreover, they have pursued pro-cyclical policies, particularly by raising expenditures in good times. Net-contributing Länder (paying into the transfer system), in contrast, have ensured fiscal sustainability through spending adjustments; they have also been less pro-cyclical. Panel vector auto-regressions confirm these findings.

This article addresses fiscal policy as a key instrument for promoting the transition to a circular economy. It is based on the hypotheses that (1) the current tax system penalizes circular activities, which are generally labour intensive, as opposed to new product manufacturing activities, which are generally intensive in materials and energy, highly automated and robotized, and (2) that the environmental taxation implemented in recent decades is unable to introduce significant changes to stop climate change or keep the economy within planetary ecological limits. This article examines the basis of an alternative tax system and tax instruments for correcting the current linear economy bias and driving the transition to a circular economy. Proposals are developed for both structural and partial reforms of the fiscal system, focusing on tax measures that can be implemented in the medium or short term to boost a circular economy. More specifically, we suggest a complete redesign of the currently opaque and significant amount of tax expenditure to transform environmentally harmful tax benefits into environmentally friendly tax measures that are suitable for the circular economy.

In connection with the upcoming changes in the area of fiscal policy, this article presents the traditional fiscal devices in Poland and the planned concept of their modernization. For this purpose, it describes traditional fiscal equipment operating on the Polish market, which, notably, has not been characterised in detail in the literature so far. Therefore, to the best of her knowledge, the author made the first systematic description and classification of devices used for transaction fiscalisation and also comprehensively presented the current structure of this market. An important objective of the work was to present an innovative concept of online fiscalisation. The author proposed her own definition of this concept. As the solution is highly advanced, it was presented on the basis of technical documentation, internal reports of Polish and foreign companies-producers of cash registers, as well as reports of consulting companies, especially from countries where the online fiscal system is already operating. The article also uses a part of the author’s expert study on the expected effects of the introduction of “online cash registers”.
