The European Union fulfills its emissions reductions commitments by means of an emissions trading scheme covering some part of each member state’s economy and by national emissions control in the rest of their economies. The member states also levy energy/emissions taxes overlapping with the...

In a group of countries like the European Union all countries seek to achieve their national CO2 emissions target by a joint emissions trading scheme covering some part of their economies (trading sector) and by a national emissions tax in the rest of their economies (nontrading sector)....

Tradable black (CO2) and green (renewables) quotas gain in popularity and stringency within climate policies of many OECD countries. The overlapping regulation through both instruments, however, may have important adverse economic implications. Based on stylized theoretical analysis and...

This paper studies the design of tax systems that implement a planner’s second-best allocation in a market economy. An example shows that the widely used Mirrleesian (1976) tax system cannot implement all incentive-compatible allocations. Hammond’s (1979) “principle of taxation” proves...

We develop a theory of social planning with a concern for economic coercion, which we define as the difference between consumers’ actual utility, and the “counterfactual” utility they expect to obtain if they were able to set policy themselves. Reasons to limit economic coercion include...

Globalization is eroding the efficiency of conventional taxes, such as VAT´s (value added taxes). Meanwhile, a new form of taxation, levied on bank transactions, was successfully used in Brazil (1993-2007). Based on digital technology, this tax innovation proved to be evasion-proof, more...

Many countries levy reduced-rate indirect taxes on newspapers, with proclaimed policy goals of stimulating investment in journalism and ensuring low newspaper prices. However, by taking into account the fact that the media industry operates in two-sided markets, we find the paradoxical result...

The paper estimates the distributional implications of income tax evasion in Hungary based on a random sample of administrative tax records of 230 thousand individuals. Gross incomes in the administrative tax records are compared with those in a nationally representative household budget survey,...

This paper examines the efficient provision of goods in two-sided markets and characterizes optimal specific and ad-valorem taxes. We show that (i) a monopoly may have too high output compared to the social optimum; (ii) output may be reduced by imposing negative value-added taxes (subsidy) or...

This paper analyzes the effects of specific and ad valorem taxation in an industry with downstream and upstream oligopoly. We find that in the short run, i.e. when the number of firms in both markets is exogenous, the results concerning tax incidence tend to be qualitatively similar to models...
