We study the impact of research collaborations in coauthorship networks on research output and how optimal funding can maximize it. Through the links in the collaboration network, researchers create spillovers not only to their direct coauthors but also to researchers indirectly linked to them....

The diffusion of knowledge in the world generates positive externalities if knowledge flows increase the productivity of R&D. Our work analyzes knowledge diffusion and knowledge externalities in generating innovation and in determining productivity. We first estimate the determinants of...

Research in behavioral economics has uncovered the widespread phenomenon of people making decisions against their own good intentions. In these situations, the government might want to intervene, indeed individuals might want the government to intervene, to induce behavior that is closer to what...

In the context of several examples of problems associated with present budgetary conventions, I revisit Musgrave's conceptual division of the government's program into Allocation, Distribution and Stabilization Branch subbudgets. I suggest progress towards Musgrave's ideal of a more informative...

To help first- or second-year graduate students in economics apply their theoretical training, this paper shows how to solve a simple and intuitive computable general equilibrium (CGE) model using a calculator. Because this simplified Harberger model uses Cobb Douglas functional forms for...

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...

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...

The Fiscal Theory of the Price Level (FTPL) rejects the fundamental 'Ricardian' proposition, that the government budget constraint must hold identically, that is for all admissible values of the variables entering the budget constraint. Accordingly, if the government is to meet its contractual...

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...
