A growing body of work has shown that aggregate shocks affect the formation of preferences and beliefs. This article reviews evidence from sociology, social psychology, and economics to assess the relevance of aggregate shocks, whether the period in which they are experienced matters, and whether they alter preferences and beliefs permanently. We review the literature on recessions, inflation experiences, trade shocks, and aggregate non-economic shocks including migrations, wars, terrorist attacks, pandemics, and natural disasters. For each aggregate shock, we discuss the main empirical methodologies, their limitations, and their comparability across studies, outlining possible mechanisms whenever available. A few conclusions emerge consistently across the reviewed papers. First, aggregate shocks impact many preferences and beliefs, including political preferences, risk attitudes, and trust in institutions. Second, the effect of shocks experienced during young adulthood is stronger and longer lasting. Third, negative aggregate economic shocks generally move preferences and beliefs to the right of the political spectrum, while the effects of non-economic adverse shocks are more heterogeneous and depend on the context.

We estimate a bilateral gravity equation for emigration rates controlling for decadal weather averages of temperature, precipitation, droughts, and extreme precipitation in origin countries. Using the parameter estimates of the gravity equation, we estimate global, regional, and country-by-country emigration flows using different population and climate scenarios. Global emigration flows are projected to increase between 73 and 91 million in 2030-2039; between 83 and 102 million in 2040-2049; between 88 and 121 in 2050-59, and between 87 and 133 million in 2060-2069. Changes in emigration flows are mainly due to population growth in the origin countries.

Our work is positioned at the intersection of migration and climate change—two key forces shaping the economic outlook of many countries. The analysis explores: (i) the relative importance of origincountry vs destination-country factors in explaining migration patterns; (ii) importance of climate disasters as driver of cross-border migration; and (iii) the importance of climate-driven migration on the overall impact of climate on macroeconomic outcomes. It arrives at the following main findings. First, both origin-country and destination-country contribute to explaining migration outflows from EMDEs, although only the global shocks seem important for advanced economies. Second, climate disasters are important for explaining the origincountry migration shocks in LICs and EMDEs, are especially relevant for smaller countries, and lead to migration of both genders, albeit relatively more for males out of LICs. Third, important portion of climate’s overall impact on economic outcomes—especially agricultural GDP, remittances, and inequality—is captured via climate-driven migration. Finally, higher investment in climate-resilient infrastructure can reduce the impact of climate on cross-border migration, and thereby, result in potentially important economic gains.

Undocumented migration from the Northern Triangle countries (El Salvador, Guatemala and Honduras) to the United States has been steadily increasing over the past 30 years, accelerating at times. The paper investigates what factors could explain this fact, by estimating an investment decision model, using annual data over 1990-2019. Economic labor market conditions (real wages and unemployment rates, especially in the U.S.) play a major role in explaining undocumented migration. Less explored drivers of undocumented migration tied to living conditions at home also explain well undocumented migration (natural disasters, coffee production, higher temperatures, and homicide rates). Tighter border enforcement measures act as a deterrent, and perceptions regarding changes of these measures could also drive up undocumented migration at times. Policies that address the root causes of migration at home, including with the U.S. help, are essential in reducing the difference between perceived benefits and expected costs of migration.

This paper examines how international remittances are affected by structural characteristics, macroeconomic conditions, and adverse shocks in both source and recipient economies. We exploit a novel, rich panel data set, covering bilateral remittances from 103 Italian provinces to 107 developing countries over the period 2005-2011. We find that remittances are negatively correlated with the business cycle in recipient countries, and increase in response to adverse exogenous shocks, such as natural disasters or large declines in the terms of trade. Remittances are positively correlated with economic conditions in the source province. Nevertheless, in the presence of similar negative shocks to both source and recipient economies, remittances remain counter-cyclical with respect to the recipient country.

This Selected Issues paper analyzes macroeconomic fluctuations in the Eastern Caribbean Currency Union (ECCU). The paper describes data, along with the estimation technique used to ensure stationarity of the data. The empirical regularities of macroeconomic fluctuations in the ECCU are described, examining the relationship between a set of macroeconomic time series and domestic output, for each of the six IMF members of the ECCU. The paper also explores the determinants of macroeconomic volatility in the ECCU.
