The problem of portfolio selection is a standard problem in financial engineering and has received a lot of attention in recent decades. Classical mean-variance portfolio selection aims at simultaneously maximizing the expected return of the portfolio and minimizing portfolio variance. In the...

This work derives explicit kernel approximations for universal kriging predictors for a class of intrinsic random function models. This class of predictors is of particular interest because they are equivalent to the standard two-dimensional thin plate smoothing splines. By introducing a...

We use a Smooth Transition Conditional Correlation GARCH (STCC-GARCH) model applied to the euro area monetary policy rates and sovereign yields of Italy, Spain and Germany at 5-year maturity to estimate the threshold level of the signals above which the sovereign bond market moves to a crisis...

Bid–ask spreads using intraday data reveal significant sensitivity to European Central Bank (ECB) macro-announcements. Effects are strongest for announcements that comprise unexpected information or a change in interest rates, and spreads rise sharply during the minutes surrounding interest...

This study gives first evidence on the consequences of the introduction of a transaction tax in Italian financial markets in 2013. We discuss the consequences of this tax on trading volume, volatility, and trading costs of FTSE MIB stocks. The structure of the tax introduction gives us the...

This study focuses on global real estate return distributions. For our analysis, we employ the class of stable distributions that has become prominent in the real estate literature. We add to the literature by undertaking a global-scale analysis for the first time. By using data since the early...

We use existing drawdown measures as well as modifications and extensions to gain insight into pronounced periods of gains and losses among global real estate companies. While there is no indication on heavier loss periods for companies that had experienced higher drawups in the previous market...

The liquidity crisis in the German Open-Ended Real Estate Funds (GOEREFs) industry was characterized by large outflows of money in several funds. Large and ongoing redemptions of fund shares held by both institutional and private / retail investors led to suspensions of redemptions, termination...

Since 2008, the German open-ended real estate fund (GOEREF) industry has experienced a critical phase of suspensions of redemption of fund shares, announced fund terminations and, eventually, introduction of a new regulation. With assets under management of over EUR 80 billion, GOEREFs are the...

The correlation between stock markets and interest rates has been discussed in numerous studies in the past, with differing results in terms of strength and direction of the relationship. This paper uses models of the multivariate GARCH type which allow for time-variability and regime changes in...
