Recent research in financial economics has shown that rare large disasters have the potential to disrupt financial sectors via the destruction of capital stocks and jumps in risk premia. These disruptions often entail negative feedback e?ects on the macroecon-omy. Research on disaster risks has...

This paper estimates the carbon leakage rate across countries, arguably a key parameter in the international climate policy discussion including on border carbon adjustment, but which remains subject to significant uncertainty. We propose innovations along two lines. First, we exploit recently...

The permanent income hypothesis implies that frictionless open economies with exhaustible natural resources should save abroad most of their resource windfalls and, therefore, feature current account surpluses. Resource-rich developing countries (RRDCs), on the other hand, face substantial...

To assess the feasibility of the national accounts treating as assets depletable resources extracted for sale, the paper examines three issues: 1. whether treating natural resources as assets when they are used requires symmetrical accounting when they enter economic reserves; 2. at what stage...

This paper assesses sustainable fiscal behavior in an economy where wealth is derived predominantly from a non-renewable resource. It explores the issue in a simple dynamic framework that highlights the structural weaknesses in the underlying budgetary position, takes into account the rate of...

This paper presents a model of optimal taxation in which both private agents and the government can default on their debt. We first consider Ramsey equilibria in which the government can precommit to its policies but in which private agents can default. We then consider sustainable equilibria in...

The main purpose of this paper is to provide an overview of approaches to assessing fiscal sustainability. It summarizes the general analytical background, focusing on the present value budget constraint, which is the benchmark against which solvency is determined, tests of sustainability...

Unlike conventional fiscal sustainability assessments, the Value-at-Risk approach developed in this paper explicitly captures the contribution of key risk variables to public sector vulnerability. In an illustrative application to Ecuador, the VaR approach confirms a significant risk of...

We investigate the impact of remittances on public debt sustainability and detail how the traditional debt-to-GDP ratio can be modified to create a more accurate representation of debt sustainability for a country that receives significant remittance inflows. The main result is that inclusion of...
