- Abstract
- Using randomized control trials (RCTs) applied over time in different countries, we study whether the economic environment affects how agents learn from new information. We show that as inflation rose in advanced economies, both households and firms became more attentive and informed about publicly available news about inflation, leading them to respond less to exogenously provided information about inflation and monetary policy. We also study the effects of RCTs in countries where inflation has been consistently high (Uruguay) and low (New Zealand) as well as what happens when the same agents are repeatedly provided information in both low-and high-inflation environments (Italy). Our results broadly support models in which inattention is an endogenous outcome that depends on the economic environment.

- Abstract
- Using a new survey of European households, we study how exogenous variation in the macroeconomic uncertainty perceived by households affects their spending decisions. We use randomized information treatments that provide different types of information about the first and/or second moments of future economic growth to generate exogenous changes in the perceived macroeconomic uncertainty of some households. The effects on their spending decisions relative to an untreated control group are measured in follow-up surveys. Higher macroeconomic uncertainty induces households to reduce their spending on non-durable goods and services in subsequent months as well as to engage in fewer purchases of larger items such as package holidays or luxury goods. Moreover, uncertainty reduces household propensity to invest in mutual funds. These results support the notion that macroeconomic uncertainty can impact household decisions and have large negative effects on economic outcomes.
