We provide a critique of the standard methodology for inequality measurement, which makes welfare comparisons between households by deflating household income and consumption with an equivalence scale. We argue that this leads to support for tax/transfer policies that significantly disadvantage low to middle income households and second earners—predominantly women. Its main...
In this paper, we estimate short- and long-term tax buoyancy for 44 sub-Saharan African (SSA) countries during 1980–2017 using time series and panel techniques. We find that the long-term tax buoyancy is either one or slightly above one for most SSA countries. Fragile states have a lower short-term tax buoyancy reflecting their institutional weaknesses. Short-term buoyancy of...
We study how a capital income tax and a wealth tax affect an investor's valuation of a company's stock in an efficient international capital market. Using a one-period model, a model of infinite horizon where the asset generates a future cash flow that is a martingale, and a finite horizon model where we abandon the martingale assumption, we find that a wealth tax and/or a...
As the COVID-19 pandemic has shaped public policies and government finances, it has also influenced the topics that public finance economists are researching. Because the 2020 International Institute of Public Finance Congress featured papers that were submitted prior to the start of the pandemic, the Congress allows us to reflect on the state of research prior to the pandemic’s...
We explore the new roles of rules of origin (ROO) when multinational enterprises (MNEs) manipulate their transfer prices to avoid a high corporate tax. The ROO under a free trade agreement (FTA) require exporters to identify the origin of exports to be eligible for a preferential tariff rate. We find that a value-added criterion of ROO restricts abusive transfer pricing by MNEs...
A growing literature emphasizes that the output effect of fiscal consolidation hinges on its composition, as the choice of increasing revenues vs cutting expenditure is not neutral. Existing studies, however, underscore the role of local governments in a federal setting. Indeed, transfer cuts at the central level might translate into higher local taxes, changing the effective...
Models of strategic debt predict that public debt increases with polarization, measured by the ideological distance between the government and its likely successor. Conversely if voters are both short-termist and also more likely to switch their vote for parties offering higher spending and public good provision when the electorate is ideologically concentrated, then debt can...
This paper uses a panel of personal income tax return data for the population of Thai tax filers to examine how individuals respond to tax subsidy for long-term savings. We utilize the 2013 tax reform that lowered the price subsidy for long-term savings in order to obtain causal identification. Our difference-in-difference analysis illustrates that there is a considerable...
It is widely agreed that in countries without major constraints on administrative capacity, a value-added tax (VAT) should tax all goods and services at a uniform rate. In these countries, VAT’s C-efficiency, that is, actual revenue over potential revenue, should be one if compliance is perfect. Under this approach, VAT’s C-inefficiency—the aggregate of the policy gap (exemptions...
Economists have adopted the Pigouvian approach to climate policy, which sets the carbon price to the social cost of carbon. We adjust this carbon price for macroeconomic uncertainty and disasters by deriving the risk-adjusted discount rate. We highlight ethics- versus market-based calibrations and discuss the effects of a falling term structure of the discount rate. Given the...
Previous research has shown that changes in the composition of tax revenue affect long-run growth. However, little is yet known about whether the way tax revenue is raised matters for growth. This paper examines whether, in the context of OECD countries, a revenue-neutral increase in the value-added tax (VAT), offset by a fall in income taxes, may have different effects on long...
The formation and allocation of an emission quota are analyzed in a common agency framework with two stages. First, the principals lobby for the size of the aggregate quota. Second, the principals lobby for the individual slices of the quota. It is shown that the slices are allocated such that the marginal profits of the principals are equalized and that the size of the aggregate...
Thin capitalization rules limit firms’ ability to deduct internal interest payments from taxable income, thereby restricting debt shifting activities of multinational firms. Since multinational firms can limit their tax liability in several ways, regulation of debt shifting may have an impact on other profit shifting methods. We therefore provide a model in which a multinational...
The Tax Cuts & Jobs Act (TCJA) introduced the most significant changes to the US international tax system in decades. The law changes have been criticized for reducing equity, benefiting wealthier business owners at the expense of individuals in the long term (while also increasing the deficit) adding to complexity, and creating incentives for shifting profits and activities...
We present a scheme for analysing income tax perturbations, applied to a real Norwegian tax reform during 2016–2018. The framework decomposes the reform into a structural reform part and a tax level effect. The former consists of a distributional impact and a social efficiency effect measured as the behavioural-induced change in tax revenue. Considering the overall welfare effect...
Divergent economic performance in many countries has led to renewed interest in place-based policies, such as the UK’s local industrial strategies at the level of Combined Authorities or Local Economic Partnerships. However, an analysis of employment data using methods from the economic complexity literature demonstrates great heterogeneity in industrial strengths and future...
We revisit the standard theoretical model of tax competition to consider imperfect mobility of both capital and labor. We show that the mobility of one factor affects the taxation of both factors and that the ”race-to-the-bottom” narrative (with burden shifting) applies essentially to capital-exporting countries. We validate our predictions using a panel of 29 OECD countries over...
Do policies and institutions matter for pre-tax income inequality? I build an annual panel of 43 countries for the period 1980–2016 to document cross-country facts. I find robust correlations between pre-tax income shares and economic policy—financial development, trade openness, government expenditure, and income taxation—even after controlling for economic development. I...

We examine how political institutions influence health expenditure by using a panel of 151 developing and developed countries for the years 2000 to 2015 and four measures of democracy. Our pooled OLS analysis shows that democracies have 20–30% higher government health expenditure relative to GDP than their autocratic counterparts. An instrumental variable approach which exploits...
Most tax agencies use letters as the method of communicating with taxpayers. Still, other technologies exist that could be more effective. This paper reports the results of a field experiment conducted by the National Tax Agency of Colombia (DIAN), using phone calls to reduce tax delinquencies. DIAN randomly assigned 34,000 tax debtors to a phone call operation using a fixed...
The year 2020 marks the centennial of the publication of Arthur Cecil Pigou’s magnum opus The Economics of Welfare. Pigou’s pricing principles have had an enduring influence on the academic debate, with a widespread consensus having emerged among economists that Pigouvian taxes or subsidies are theoretically desirable, but politically infeasible. In this article, we revisit Pigou...
