The covered bond market offers investors an alternative to developed country government securities. The valuation of covered bonds is complex. While there is some evidence of differences in the pricing of these bonds by nationality of issuer, these appear to be only weakly related to differences...

This paper studies properties of an estimator of mean-variance portfolio weights in a market model with multiple risky assets and a riskless asset. Theoretical formulas for the mean square error are derived in the case when asset excess returns are multivariate normally distributed and serially...

Empirical studies document that equity portfolios constructed to have the lowest possible risk have surprisingly high average returns. We derive an analytic solution for the long-only minimum variance portfolio under the assumption of a single-factor covariance matrix. The equation for optimal...

We show analytically under quite general conditions that time-varying implied rates of return based on analysts' earnings forecasts are only a downward biased estimator for future expected one-period returns and therefore not suited for computing market risk premia in order to resolve the equity...

The theory of capital (long-term) assets value (Sharpe, 1964, Lintner, 1965, Mossin, 1966), based on G. Markovitz's model (Markovitz, 1952,1059), has served for many years as the basis for valuations in the investment analysis and corporate finance. However, implicitly, this theory contains an...

This paper derives in closed form the optimal dynamic portfolio policy when trading is costly and security returns are predictable by signals with dierent mean-reversion speeds. The optimal updated portfolio is a linear combination of the existing port- folio, the optimal portfolio absent...

As reserve accumulation has gathered pace in recent years, and as foreign exchange (FX) reserve holdings have risen far above conventional measures of reserve adequacy, a vigorous debate has begun as to whether part of the reserves should be invested in riskier assets to reduce their financial...

This paper explores the hypothesis that investors gain information advantages through business connections made during prior employment. Mutual fund managers who previously worked as sell-side analysts put significantly more weight on the stocks they previously covered, and holdings of those...

This paper studies the contracting choices between an entrepreneur and different kinds of venture capitalists in a portfolio context. The optimal contract for the entrepreneur features investor choice, share of investment, and equity dilution as a function of her bargaining power. In our...

Examines ways in which diversification ofindustry-specialized portfolios contributes to macro-risk reduction strategiesof venture capital (VC) firms, and the factors impacting portfoliodiversification. The study starts from the premise that, although researchersstudy selection criteria for...
