Peer effects can lead to better financial outcomes or help propagate financial mistakes across social networks. Using unique data on peer relationships and portfolio composition, we show considerable overlap in investment portfolios when an investor recommends their brokerage to a peer. We argue that this is strong evidence of peer effects and show that peer effects lead to better portfolio quality. Peers become more likely to invest in funds when their recommenders also invest, improving portfolio diversification compared to the average investor and various placebo counterfactuals. Our evidence suggests that social networks can provide good advice in settings where individuals are personally connected.
UNDERSTANDING HOW HOUSEHOLDS REACT TO THE ARRIVAL OF PERMANENT AND TRANSITORY INCOME IS OF INTEREST FOR RESEARCHERS AND REGULATORS. PREVIOUS STUDIES HAD TO USE IMPRECISE SURVEY DATA TO MEASURE CONSUMPTION AND THUS CONCLUSIONS OFTEN DIVERGED. WE LEVERAGE GRANULAR PERSONAL FINANCE MANAGEMENT FINTECH DATA TO TEST FRIEDMAN'S PERMANENT INCOME HYPOTHESIS AND TO ASSESS HOUSEHOLD SPENDING ELASTICITY AND MARGINAL PROPENSITY TO CONSUME FOR VARIOUS SPENDING CATEGORIES IN RESPONSE TO DIFFERENT INCOME TYPES.
THIS STUDY INVESTIGATES WHAT HAPPENS WHEN RETAIL CUSTOMERS ARE OFFERED FREE AND UNBIASED ADVICE. USING A LARGE FIELD EXPERIMENT IT SHOWS THAT THOSE WHO ACCEPT THE OFFER (5%) ARE MORE LIKELY TO BE MALE, OLDER, WEALTHIER, MORE EXPERIENCED AND MORE FINANCIALLY SOPHISTICATED. HOWEVER, EVEN THOUGH THE ADVICE WOULD HAVE HELPED, IT ACTUALLY LARGELY FAILED TO HELP BECAUSE THE CUSTOMERS DID NOT LISTEN TO IT. OVERALL, OUR RESULTS SUGGEST THAT THE MERE AVAILABILITY OF UNBIASED FINANCIAL ADVICE IS A NECESSARY BUT NOT SUFFICIENT CONDITION FOR BENEFITING RETAIL CUSTOMERS.
RECENTLY, PASSIVE ETFS AND INDEX FUNDS HAVE BECOME POPULAR AMONG INDIVIDUAL INVESTORS. IN OUR STUDY, WE INVESTIGATE WHETHER INDIVIDUAL INVESTORS BENEFIT FROM USING THEM. WITH DATA FROM ONE OF THE LARGEST BROKERAGES IN GERMANY, WE FIND THAT INDIVIDUAL INVESTORS WORSEN THEIR PORTFOLIO PERFORMANCE AFTER USING THESE PRODUCTS IN COMPARISON TO NON-USERS. SINCE THESE SECURITIES MAKE MARKET TIMING EASIER, FURTHER ANALYSIS REVEALS THAT THE DECREASE IN USERS’ PORTFOLIO PERFORMANCE IS PRIMARILY DUE TO BAD MARKET TIMING.
Consuming dividends
(2020)
This paper studies why investors buy dividend-paying assets and how they time their consumption accordingly. We combine administrative bank data linking customers’ consumption transactions and income to detailed portfolio data and survey responses on financial behavior. We find that private consumption is excessively sensitive to dividend income. Investors across wealth, income, and age distributions increase spending precisely around days of dividend receipt. Importantly, the consumption response is driven by financially prudent investors who select dividend portfolios, anticipate dividend income, and plan consumption accordingly. Our results contribute to the literature on a dividend clientele and provide evidence of ‘planned’ excess sensitivity.
ON JUNE 18TH, WIRECARD’S SHARE PRICE PLUMMETED BY MORE THAN 60% FOLLOWING THE FIRM’S ADMISSION OF BEING SUBJECT TO “ENORMOUS FRAUD” AND BILLIONS OF EUROS MISSING. THIS REPORT DOCUMENTS GERMAN RETAIL INVESTORS’ RESPONSE AND FINDS THAT THE POPULARITY OF WIRECARD AMONG RETAIL INVESTORS LED TO SUBSTANTIAL LOSSES IN THEIR PORTFOLIOS. THESE LOSSES WERE EXACERBATED BY STRONG BUYING SENTIMENT AFTER THE ANNOUNCEMENT. THE FAILING STOCK WAS PURCHASED BY INVESTORS ALREADY ENGAGED IN IT AS WELL AS NON-EXPOSED CUSTOMERS.
The European Commission has published a Green Paper outlining possible measures to create a single market for capital in Europe. Our comments on the Commission’s capital markets union project use the functional finance approach as a starting point. Policy decisions, according to the functional finance perspective, should be essentially neutral (agnostic) in terms of institutions (level playing field). Our main angle, from which we assess proposals for the capital markets union agenda, are information asymmetries and the agency problems (screening, monitoring) which arise as a result. Within this perspective, we make a number of more specific proposals.
Financial literacy affects wealth accumulation, and pension planning plays a key role in this relationship. In a large field experiment, we employ a digital pension aggregation tool to confront a treatment group with a simplified overview of their current pension claims across all pillars of the pension system. We combine survey and administrative bank data to measure the effects on actual saving behavior. Access to the tool decreases pension uncertainty for treated individuals. Average savings increase - especially for the financially less literate. We conclude that simplification of pension information can potentially reduce disparities in pension planning and savings behavior.
