Starting from the Merton framework for firm defaults, we provide theanalytics and robustness of the relationship between defaultprobabilities and default correlations. We show that loans with higherdefault probabilities will not only have higher variances but also highercorrelations with other...

According to conventional wisdom, long-term bonds are appropriate for conservative long-term investors. This paper develops a model of optimal consumption and portfolio choice for infinite-lived investors with recursive utility who face stochastic interest rates, solves the model using an...

This paper analyzes the portfolio allocations of couple-headed, Hispanic families using Survey of Income and Program Participation (SIPP) data. Our results reveal that Hispanic couples as a group are less wealthy than otherwise similar white couples, although there is substantial variation...

This paper considers a multivariate t version of the Gaussian dynamic conditional correlation (DCC) model proposed by Engle (2002), and suggests the use of devolatized returns computed as returns standardized by realized volatilities rather than by GARCH type volatility estimates. The t-DCC...

This article investigates the sensitivity analysis of mean-variance portfolio holdings to changes in the upper bounds. The optimization problem studied in this paper is, thus, constrained by a restriction that no more than certain portion of wealth can be invested in any one security. Our...

This article is centred around the notions of shareholder value orientation and financialisation. Shareholder value orientation is reflected by a high dividend payout ratio applied by firms and the reluctance of firms to finance physical investment via new equity issues. Financialisation is the...

We explore the role of corporate insiders vs. firms as traders of last resort. We develop a simple model of insider trading in which insiders provide price support, as well as liquidity, in security markets. Consistent with the model predictions we find that in the US markets insiders’ trading...

We experimentally investigate whether the satisficing approach is absorbable, i.e., whether it still applies after participants become aware of it. In a setting where an investor decides between a riskless bond and either one or two risky assets, we familiarize participants with the satisficing...

The objective of this paper is twofold: (1) to analyze an optimal portfolio rebalancing by a fund manager in response to a "volatility shock" in one of the asset markets, under sufficiently realistic assumptions about the fund manager's performance criteria and portfolio restrictions; and (2) to...
