Estimating difference-in-differences regressions around Draghi’s “Whatever It Takes” speech in July 2012 with household data from the ECB’s Household Finance and Consumption Survey, we find ...

ON THE INTERNATIONALIZATION OF PORTFOLIOS * [PDF]
Oxford Economic Papers, 1992 Portfolio theory has been an important component of open economy macroeconomic models. In those models, it is essential to distinguish among several categories of assets, both foreign and domestic, and to specify the demands and supplies. This framework has become increasingly relevant.

Open Praxis, 2013 Growing global commitments to open learning through the use of Open Educational Resources (OERs) are accompanied by concerns over what “to do” with that learning when learners present it to traditional institutions for assessment and accreditation.

Cover's universal portfolio, stochastic portfolio theory, and the numéraire portfolio [PDF]
Mathematical Finance, 2018 AbstractCover's celebrated theorem states that the long‐run yield of a properly chosen “universal” portfolio is almost as good as that of the best retrospectively chosen constant rebalanced portfolio. The “universality” refers to the fact that this result is model‐free, that is, not dependent on an underlying stochastic process.

Functional Portfolio Optimization in Stochastic Portfolio Theory
SIAM Journal on Financial Mathematics, 2022 In this paper we develop a concrete and fully implementable approach to the optimization of functionally generated portfolios in stochastic portfolio theory. The main idea is to optimize over a family of rank-based portfolios parameterized by an exponentially concave function on the unit interval. This choice can be motivated by the long term stability
