We study how cross-country macroeconomic spillovers caused by sovereign default affect equilibrium bailouts. Because of portfolio diversification, the default of one country causes a macroeconomic contraction also in other countries. This generates a self-interest for these other countries to...

I examine the role of political instability as a potential explanation for the lack of capital flows from rich countries to poor countries (i.e. the `Lucas Paradox'). Using panel data from 1984 to 2014, I document the following: (i) developed countries exhibit larger inflows of foreign direct...

I analyze how partisan conflict about trade policy affects foreign direct investment flows to the US using a novel indicator, the Trade Partisan Conflict Index (TPCI). Partisan conflict is relevant for the evolution of cross-border capital flows because the expected returns on investment...

American politics have been characterized by a high degree of partisan conflict in recent years. Combined with a divided government, this has led not only to significant Congressional gridlock, but also to spells of high fiscal policy uncertainty. The unusually slow recovery from the Great...

Entitlement programs have become an increasing component of total government spending in the US over the last six decades. To some observers, this growth of the welfare state is excessive and unwarranted. To others, it is a welcome counter-acting force to the rapid increase in income inequality....

We study how political constraints, characterized by the degree of flexibility to choose fiscal policy, affect the probability of sovereign default. To that end, we relax the assumption that policymakers always repay their debt in the dynamic model of fiscal policy developed by Battaglini and...

We develop an ECON-EPI network model to evaluate policies designed to improve health and economic outcomes during a pandemic. Relative to the standard epidemiological SIR set-up, we explicitly model social contacts among individuals and allow for heterogeneity in their number and stability. In...

Do mandatory spending rules improve social welfare? We analyze a dynamic political-economy model in which two parties disagree on the split of a fixed budget between public goods and private transfers. Under a mandatory spending rule, expenditures are governed by criteria set by enacted law,...

We develop a theory of optimal government debt in which publicly-issued and privately-issued safe assets are substitutes. While government bonds are backed by future tax revenues, privately-issued safe assets are backed by the future repayment of pools of defaultable private loans. We find that...

We study how the structure of social media networks and the presence of fake news might affect the degree of misinformation and polarization in a society. For that, we analyze a dynamic model of opinion exchange in which individuals have imperfect information about the true state of the world...
