Does Federalism Lead to Excessively High Taxes

The relative strengths of vertical and horizontal tax externalities turn on the balance between the interest responsiveness of the supply of savings and demand for capital, the extent to which immobile factors are taxed by the states, and the strength of preferences between federal and state expenditures. The vertical externality will dominate if the aggregate tax base of the federation is responsible to the state tax instrument. Tax interactions in federations are more complex than has often been supposed.

Corruption Around the World: Evidence from a Structural Model

The causes and consequences of corruption have attracted much attention in recent years by both academics and policy makers. Central in the discussion on the impact of corruption are perception-based indices. While informative, these indices are ordinal in nature and hence provide no indication of how much economic loss is attributed to corruption. Arguably, this shortcoming is rooted in the lack of a structural model. This is the issue addressed in this paper. By treating corruption as a latent variable that is directly related to its underlying causes, a cardinal index of corruption is derived for approximately 100 countries. This allows us to compute a measure of the losses due to corruption as a percentage of GDP per capita.

A Spatial Analysis of Provincial Corporate Income Tax Responses: Evidence from Canada

Canadian provincial governments. The results show that there is a statistically significant positive fiscal interaction among a subset of provinces and between all provinces and the federal government. Provincial corporate income taxes are also found to be negatively related to equalization entitlements, general federal transfers, and the federal corporate income tax. A robustness check on the fiscal relationship between Ontario and Quebec verifies the existence of significant bi-directional fiscal interdependencies. The paper also introduces U.S state corporate income taxes as covariates and examines their interaction with Canadian provinces.

On production efficiency in federal systems

Abstract This paper emphasises the role of the allocation of rents, between the levels of government within a federal economy, in the achievement of production efficiency. It is shown that in a federal economy, in the absence of vertical transfers, production efficiency dictates rents should be allocated to the upper (federal) level of government.

The Comparison of Ad Valorem and Specific Taxation Under Uncertainty

The comparison between specific (per unit) and ad valorem (percentage) taxation has been one of the oldest issues in public finance. In Cournot markets, with deterministic costs structures, conventional wisdom has it that ad valorem taxation tax-revenue dominates specific. It is shown that in the presence of uncertainty, regarding firms’ cost structures, and under reasonable conditions, the conventional wisdom might not hold. The implication of this, from a policy perspective, is that the precise evaluation of the two types of taxation requires an explicit consideration of cost uncertainty.

Information transmission within federal fiscal architectures: Theory and evidence

This paper explores the role of information transmission and misaligned interests across levels of government in explaining variation in the degree of decentralization across countries. Within a two-sided incomplete information principal-agent framework, it analyzes two alternative policy-decision schemes –‘decentralization’ and ‘centralization’– when ‘knowledge’ consists of unverifiable information and the quality of communication depends on the conflict of interests between the government levels. It is shown that, depending on which level of policy decision-making controls the degree of decentralization, the extent of misaligned interests and the relative importance of local and central government knowledge affects the optimal choice of policy-decision schemes. The empirical analysis shows that countries’ choices depend on the relative importance of their private information and the results differ significantly between unitary and federal countries.

The Impact of Institutions on the Shadow Economy and Corruption: A Latent Variables Approach

The shadow economy (also known as the black or underground economy) covers a vast array of trade, goods and services that are not part of the official economy of a country. This original and comprehensive Handbook presents the latest research on the size and development of the shadow economy, which remains an integral component of the economies of most developing and many developed countries.
