Competition in Portfolio Management: Theory and Experiment

Competition in Portfolio Management: Theory and Experiment

We explore theoretically and experimentally the general equilibrium price and allocation implications of delegated portfolio management when the investor-manager relationship is non-exclusive. Investors transfer their securities allocations to managers, managers trade in a competitive marketplace to achieve new allocations, and payo↵s are distributed back to investors after subtraction of a por...

Portfolio Life Cycle Selection – Theory and Experiment

In this paper, I compare the results from a laboratory experiment, in which individuals could allocate their funds between a risky asset and a risk-free zero return fund, with stochastic dynamic optimization policies based on expected utility maximization. Specifically, I focus on the predictions based on a negative exponential and concave quadratic utility. In addition, I look at the applicabi...

Prices and Portfolio Choices in Financial Markets: Theory and Experiment∗

Most tests of asset pricing models address only the pricing predictions – perhaps because the portfolio choice predictions are obviously wrong. But how can asset-pricing theory be right if the portfolio choice theory on which it rests is wrong? This work builds and observes experimental markets in which risky and riskless assets are traded. Risk aversion is a robust phenomenon in experimental s...

Modern Portfolio Theory, Digital Portfolio Theory and Intertemporal Portfolio Choice

The paper compares three portfolio optimization models. Modern portfolio theory (MPT) is a short-horizon volatility model. The relevant time horizon is the sampling interval. MPT is myopic and implies that investors are not concerned with long-term variance or mean-reversion. Intertemporal portfolio choice is a multiple period model that revises portfolios continuously in response to relevant s...
