The COVID-19 crisis poses new policy challenges and has spurred new research agendas in public economics. In this article, we selectively reflect on how the field of public economics has been shaped by the COVID-19 pandemic and discuss several areas where more research is necessary. We highlight...

We develop a two-region model where the decentralized provision of spillover goods can be financed by means of taxes or user fees. In order to enforce the fees regions have to invest in exclusion. We show that a decentralized solution tends to be inefficient. There will be over-investment in...

The fiscal decentralization impulse now sweeping the world often leads to partial decentralization, where subnational governments are funded by central transfers, rather than leading to full local autonomy. Despite the practical importance of this arrangement, the literature contains no economic...

The Decentralization Theorem (Oates, 1972) is central to the discussion of fiscal federalism. We revisit the role of consumption spillovers in evaluating the merits of (de)centralization. Unlike the general prediction, a higher degree of spillovers may reduce the difference in utility of...

A growing literature has shown that behavioral biases influence consumer choices. Such so-called internalities are ubiquitous in many settings, including energy efficiency investments and the consumption of sin goods, such as cigarettes and sugar. In this paper, we use a mechanism design...

Experimental and behavioral economics are well established branches in the economic science. This essay presents and discusses some results and behavioral regularities from these fields which are of potential importance for public policy. After a brief introduction of what experimental and...

Climate action requires significant public- and private sector investment to achieve meaningful reductions in carbon emissions. This paper documents that large-scale austerity, coupled with barriers to flows of data and a lack of (digital) skills in (local) government, may have been 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 (IIPF) Congress featured papers that were submitted prior to the start of the...

This paper incorporates a bubble term in the standard FTPL equation to explain why countries with persistently negative primary surpluses can have a positively valued currency and low inflation. It also provides an example with closed-form solutions in which idiosyncratic risk on capital returns...

Many important questions in the field of public finance can be viewed as problems involving public policies in open economies. This paper draws together, from that perspective, a wide range of topics in public economics, emphasizing the implications of resource mobility for our understanding of...
