Optimal portfolio choice under loss aversion
Prospect theory and loss aversion play a dominant role in behavioral finance. In this paper we derive closed-form solutions for optimal portfolio choice under loss aversion. When confronted with gains a loss averse investor behaves similar to a portfolio insurer. When confronted with losses, the investor aims at maximizing the probability that terminal wealth exceeds his aspiration level. Our analysis indicates that a representative agent model with loss aversion cannot resolve the equity premium puzzle. We also extend the martingale methodology to allow for more general utility functions and provide a simple approach to incorporate skewed and fat-tailed return distributions
Retirement saving with contribution payments and labor income as a benchmark for investments.
In this paper we study the retirement saving problem from the point of view
of a plan sponsor, who makes contribution payments for the future retirement
of an employee. The plan sponsor considers the employee's labor income as
investment-benchmark in order to ensure the continuation of consumption
habits after retirement. We demonstrate that the demand for risky assets
increases at low wealth levels due to the contribution payments. We quantify
the demand for hedging against changes in wage growth and find that it is
relatively small. We show that downside-risk measures increase risk-taking
at both low and high levels of wealth
Investing in a real world with mean-reverting inflation.
People are concerned about maintaining purchasing power in times of rising
inflation. We formulate investment objectives in terms of real wealth,
assuming investors derive utility from the number of goods they can buy with
their monetary wealth. We derive closed-form solutions for the portfolio
choice problem of constant relative risk averse investors, under the
assumption that inflation rates are mean-reverting. We consider alternative
specifications for the inflation compensation offered by the available
assets, in order to study the effect on portfolio choice and welfare.
Moreover, we study the added value of inflation-indexed bonds for the
investor in our real framework
From boom til bust: how loss aversion affects asset prices
In 1996 Alan Greenspan warned that stock prices were "unduly escalated" and reflected "irrational exuberance". In this paper we describe an economy that can support a prolonged surge of asset prices, accompanied by a sharp increase of volatility. We study an equilibrium model where some agents are risk averse while others have loss averse preferences over wealth, according to prospect theory. We derive closed-form solutions for the equilibrium prices. In good states of the world, the loss averse
investors with wealth above the threshold are momentum traders, thereby pushing prices far above the level in the benchmark economy. In moderately bad states of the world, the loss averse investors are contrarian, and
equilibrium prices are kept relatively high and stable. Finally in extremely bad states, the loss averse investors are forced to retreat from the stock market in order to avoid bankruptcy, resulting in a sharp price drop
Dynamic asset allocation and downside-risk aversion
This paper considers dynamic asset allocation in a mean versus downside-risk framework. We derive closed-form solutions for the optimal portfolio weights when returns are lognormally distributed. Moreover, we study the impact of skewed and fat-tailed return distributions. We find that the optimal fraction invested in stocks is V-shaped: at low and high levels of wealth the investor increases the stock weight. The optimal strategy also exhibits reverse time-effects: the investor allocates more to stocks as the horizon approaches. Furthermore, the investment strategy becomes more risky for negatively skewed and fat-tailed return distributions
Compulsive gambling in the financial markets: Evidence from two investor surveys
This study shows that a group of individual investors in the financial markets displays symptoms of compulsive gambling, or an addiction to trading, based on a standard diagnostic checklist from the American Psychiatric Association. In a representative sample of Dutch retail investors, we find that 4.4% of the investors meet the criteria for compulsive gambling in the financial markets. Another 3.6% meet the criteria for problem gambling, which is a less severe form of gambl
Ambiguity Aversion and Household Portfolio Choice Puzzles: Empirical Evidence
We test the relation between ambiguity aversion and five household portfolio choice puzzles: nonparticipation in equities, low allocations to equity, home-bias, own-company stock ownership, and portfolio under-diversification. In a representative US household survey, we measure ambiguity preferences using custom-designed questions based on Ellsberg urns. As theory predicts, ambiguity aversion is negatively associated with stock market participation, the fraction of financial assets in stocks, and foreign stock ownership, but it is positively related to own-company stock ownership. Conditional on stock ownership, ambiguity aversion is related to portfolio under-diversification, and during the financial crisis, ambiguity-averse respondents were more likely to sell stocks

Model Uncertainty and Exchange Rate Forecasting
We propose a theoretical framework of exchange rate behavior where investors focus on a subset of economic fundamentals. We find that any adjustment in the set of predictors used by investors leads to changes in the relation between the exchange rate and fundamentals. We test the validity of this framework via a backward elimination rule which captures the current set of fundamentals that best predicts the exchange rate. Out-of-sample forecasting tests show that the backward elimination rule significantly beats the random walk for four out of five currencies in our sample. Further, the currency forecasts generate economically meaningful investment profits
