In diesem Beitrag wird ein Vorschlag vorgestellt, wie es trotz langfristiger Niedrigzinsen möglich ist, die vor 18 Jahren eingeführte Riester-Rente so umzugestalten, dass alle Beteiligten davon profitieren. Wird die Mindestauszahlung am Ende der Vertragslaufzeit nur für die Eigenbeiträge, nicht aber für die staatlichen Zulagen garantiert, können deutlich höhere Renditen erzielt werden. Unter dem Strich haben dann nicht nur Privatleute mehr Geld aus ihrer Altersvorsorge, sondern der Staat wird mehr Steuern einnehmen und die Anbieter haben mehr Spielraum für bedarfsgerechte Produktgestaltung.
Self-control failure is among the major pathologies (Baumeister et al. (1994)) affecting individual investment decisions which has hardly been measurable in empirical research. We use cigarette addiction identified from checking account transactions to proxy for low self-control and compare over 5,000 smokers to 14,000 nonsmokers. Smokers self-directing their investment trade more frequently, exhibit more biases and achieve lower portfolio returns. We also find that smokers, some of which might be aware of their limited levels of self-control, exhibit a higher propensity than nonsmokers to delegate decision making to professional advisors and fund managers. We document that such precommitments work successfully.
INDIVIDUALS WITH LOWER SELF-CONTROL OFTEN FAIL IN STICKING TO THEIR PLANS WHEN FACING STRONG TEMPTATIONS. ARE THEY ALSO PRONE TO EXHIBIT INVESTMENT BIASES AND SHOW A MORE IMPULSIVE TRADING BEHAVIOR WHILE FORFEITING POTENTIAL PERFORMANCE IN A FINANCIAL CONTEXT? WE USE CIGARETTE ADDICTION, IDENTIFIED THROUGH CHECKING ACCOUNT TRANSACTIONS, AS A PROXY FOR LOW SELFCONTROL AND COMPARE THE INVESTMENT BEHAVIOR OF SMOKERS TO THAT OF NONSMOKERS TO ADDRESS THIS QUESTION EMPIRICALLY.
Smart(phone) investing? A within investor-time analysis of new technologies and trading behavior
(2021)
Using transaction-level data from two German banks, we study the effects of smartphones on investor behavior. Comparing trades by the same investor in the same month across different platforms, we find that smartphones increase purchasing of riskier and lottery-type assets and chasing past returns. After the adoption of smartphones, investors do not substitute trades across platforms and buy also riskier, lottery-type, and hot investments on other platforms. Using smartphones to trade specific assets or during specific hours contributes to explain our results. Digital nudges and the device screen size do not mechanically drive our results. Smartphone effects are not transitory.
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.
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.
