We seek to understand how Laffer curves differ across countries in the US and the EU-14, thereby providing insights into fiscal limits for government spending and the service of sovereign debt. As an application, we analyze the consequences for the permanent sustainability of current debt...

The Internet comprises thousands of independently operated networks, where bilaterally negotiated interconnection agreements determine the flow of data between networks. The European Union's General Data Protection Regulation (GDPR) imposes strict restrictions on processing and sharing of...

How have labor market institutions and welfare-state transfers affected jobs and productivity in Western Europe, relative to industrialized Pacific Rim countries? Orthodox criticisms of European government institutions are right in some cases and wrong in others. Protectionist labor-market...

We present novel insights on the role of international trade following unanticipated government spending and income tax changes in a flexible exchange rate environment. In a simple two-country, two-good model, we show analytically that fiscal multipliers can be larger in economies more open to...

In principle, international differences in fiscal policy may be related to differences in optimal fiscal positions, funding constraints, political economy factors and fiscal control problems.
