Assessing the Impact of Policy Changes on a Nowcast
Mr. Sam Ouliaris
and
Ms. Celine Rochon
Nowcasting enables policymakers to obtain forecasts of key macroeconomic indicators using higher frequency data, resulting in more timely information to guide proposed policy changes. A significant shortcoming of nowcasting estimators is their “reduced-form” nature, which means they cannot be used to assess the impact of policy changes, for example, on the baseline nowcast of real GDP. This paper outlines two separate methodologies to address this problem. The first is a partial equilibrium approach that uses an existing baseline nowcasting regression and single-equation forecasting models for the high-frequency data in that regression. The second approach uses a non-parametric structural VAR estimator recently introduced in Ouliaris and Pagan (2022) that imposes minimal identifying restrictions on the data to estimate the impact of structural shocks. Each approach is illustrated using a country-specific example.

The Macroeconomic Returns of Investment in Resilience to Natural Disasters under Climate Change: A DSGE Approach
Emilio Fernández Corugedo
,
Andres Gonzalez
, and
Mr. Alejandro D Guerson
This paper presents a Markov switching dynamic stochastic general equilibrium model designed to evaluate the macroeconomic return of adaptation investment to natural disasters (NDs) and the impact of climate change. While the model follows the existing literature in assuming that NDs destroy a share of the public and private capital stocks and a government that can invest in adaptation at an additional cost, it adds several features that are key to the analysis, both in the near (transition) and long (steady state) terms. Those include incomplete markets, financial frictions with collateral constraints, foreign remittances, full menu of tax and government spending instruments, and endogenous climate risk premium. The model is calibrated to the case of Dominica. It finds that NDs have large and persistent negative effects on output and public finances. It also shows that adaptation investment has large returns in terms of private investment, employment, output and tax revenue in the long term, especially under climate change.

Waiting for Godot? The Case for Climate Change Adaptation and Mitigation in Small Island States
Mr. Serhan Cevik
Global warming is the most significant threat to ecosystems and people’s health and living standards, especially in small island states in the Caribbean and elsewhere. This paper contributes to the debate by analyzing different options to scale up climate change mitigation and adaptation. In particular, the empirical analysis indicates that increasing energy efficiency and reducing the use of fossil fuel in electricity generation could lead to a significant reduction in carbon emissions, while investing in physical and financial resilience would yield long-run benefits. From a risk-reward perspective, the advantages of reducing the risks associated with climate change and the health benefits from higher environmental quality clearly outweigh the potential cost of climate change mitigation and adaptation in the short run. The additional revenue generated by environmental taxes could be used to compensate the most vulnerable households, building a multilayered safety net, and strengthening structural resilience.

Growth at Risk from Natural Disasters
Mr. Tamim Bayoumi
,
Mr. Saad N Quayyum
, and
Sibabrata Das
The paper analyzes the impact of natural disasters on per-capita GDP growth. Using a quantile regressions and growth-at-risk approach, the paper examines the impact of disasters and policy choices on the distribution of growth rather than simply its average. We find that countries that have in place disaster preparedness mechanisms and lower public debt have lower probability of witnessing a significant drop in growth as a consequence of a natural disaster, but our innovative methodology in this paper finds that the two policies are complements since their effectiveness vary across different disaster scenarios. While both are helpful for small to mid-size disasters, lower debt—and hence more fiscal space—is more beneficial in the face of very large disasters. A balanced strategy would thus involve both policies.

Estimating the Impact of External Shocks on the ECCU: Application to the COVID Shock
Vivian Parlak
,
Mr. Gonzalo Salinas
, and
Mr. Mauricio Vargas
We measure the impact of frequent exogeneous shocks on small ECCU economies, including changes to global economic activity, tourism flows, oil prices, passport sales, FDI, and natural disasters. Using Canonical-Correlation Analysis (CCA) and dynamic panel regression analysis we find significant effects of most of these shocks on output, while only fluctuations in oil prices have significant effects on inflation. Results also suggest a significant impact of FDI and passport sales on the external balance, a link that CCA identifies as the strongest among all analyzed relations. The model also shows how Covid-19 related shocks lead to substantial contractions in output in all ECCU countries and deterioration of the current account balance in most of them, depending on countries’ tourism dependency.
