How return and risk experiences shape investor beliefs and preferences

Combining brokerage records and matching monthly survey measurements of a sample of individual investors from the Netherlands for the period April 2008 through March 2009, we examine how individual investors update their beliefs (return expectations and risk perceptions) and preferences (risk tolerance) as a result of their personal return and risk experiences. We find that investors' past returns positively impact return expectations and risk tolerance, and negatively impact risk perceptions. Realised risk, however, has no effect. That is, even in a highly volatile stock market period in which risk appears very salient, investors do not take it into account when updating their beliefs and preferences.

Material and nonmaterial impacts of the COVID-19 pandemic: Evidence from a low-income country

How have COVID-19-related restrictions affected consumption levels and life satisfaction in low-income countries? We conducted phone surveys with 577 households in Liberia to compare consumption patterns across three points in time: November 2019 (pre-COVID-19), May 2020 (short term), and September 2020 (medium term). This article analyzes the impacts of the Covid-19 pandemic and the related restrictions on food and nonfood consumption, which we categorize as “material” welfare and life satisfaction, which we categorize as “nonmaterial” welfare. We find differences between food and nonfood consumption patterns under pandemic conditions. In particular, consumption by households dependent on food and labor markets was negatively affected by the pandemic. In terms of life satisfaction, we find that most respondents perceived their lives to have worsened due to the pandemic.
