"50 Basis Points of Marriage Counseling: Monetary Policy Shocks and Marital Stability" with Frode Martin Nordvik
Abstract: This study investigates the impact of monetary policy shocks on marital stability using detailed individual-level register data from Norway. Tracking the entire population of married individuals aged 20--40 from 2005 to 2018---approximately 400,000 individuals---we find that positive monetary policy shocks---reducing disposable income---reduce the likelihood of divorce, particularly for individuals with higher interest rate exposure (net debt). At average net debt levels, a one-standard-deviation positive monetary policy shock reduces divorce probability by approximately 15\% among liquidity-constrained individuals, whereas high-income and net creditor individuals are unaffected. Additionally, our findings suggest an asymmetric effect: positive policy shocks reduce divorce risk more significantly than negative shocks increase it. These results align with loss aversion behavior, as liquidity-constrained individuals respond more strongly to unexpected losses in disposable income than to gains.
"Leaving money on the table: Consumer Inattention in Mobile Subscription" with Bjørn-Atle Reme
Abstract: We study consumer inattention to changing market prices using detailed customer-level data from a mobile operator. The data cover an unanticipated introduction of new price plans, causing a sudden change in the choice set available to the customers. We demonstrate that this induces switching, but that the extent of switching is independent of the degree to which the new choice set would lower costs. The behavior is consistent with customers being inattentive, and that the launch triggered their attention, leading to reoptimization. We also document two empirical patterns relevant for policies aimed at increasing customer awareness and switching. First, that the most responsive customers are those who are better optimized prior to the change of price plans. Second, while switching on average decreases the customer monthly costs, this was not the case among customers who were triggered to switch by the change in market prices.
