The Bootstrap Efficient Frontier for Mixed-Asset Portfolios

How much in real estate? To answer this question, uncertainty needs to be introduced into the efficient frontier, so that a confidence interval can be estimated for the real estate weight in a mixed‐asset portfolio. Instead of focusing on a single optimal portfolio, this study examines the entire efficient frontier using the traditional point estimate method and the bootstrap simulation. The bootstrap distributions of the estimated weight vectors indicate that their confidence intervals are large enough to render them effectively useless. Once uncertainty is introduced, the efficient frontier becomes fuzzy and the weight vectors become even fuzzier.

The wealth effects of real estate transactions: The case of REITs

Recent literature analyzing corporate acquisitions and sales of real estate has shown that statistically significant gains accrue to both buyers and sellers when the transaction is announced. In this paper, we focus solely on the real property transactions of tax-qualified Real Estate Investment Trusts (REITs) to determine if REIT shareholders experience a similar pattern of positive wealth effects. We find that REITs do not experience any significant wealth effects from transaction announcements. However, we provide evidence that a significant positive wealth effect does occur upon the announcement of a sale transaction when the sale is associated with an increase in REIT dividends.
