We study optimal investment with multiple assets in the presence of small proportional transaction costs. Rather than computing an asymptotically optimal no-trade region, we optimize over suitable trading frequencies. We derive explicit formulas for these and the associated welfare losses due to...

Markov-Ketten haben bei der Modellierung von ökonomischen Sachverhalten eine Vielzahl von Anwendungen. In den Wirtschaftswissenschaften steht oft ein Portfolio von Markov -Ketten im Mittelpunkt des Interesses, z.B. das Kreditportfolio einer Bank oder das Vertragsportfolio einer Versicherung. In...

Despite the fact that there is a substantial literature on the analysis of volatility spillovers between stock returns and domestic exchange rates, surprisingly, little empirical research has examined volatility spillovers between oil prices and emerging economies, where a clear gap of research...

This paper addresses several broad issues for governments aiming to encourage private sector investment in low-carbon climate resilient (LCR) infrastructure, in both developed and developing world contexts. LCR infrastructure is defined, recognizing the interdependencies between infrastructure...

We present a standard model of financial innovation, in which intermediaries engineer securities with cash flows that investors seek, but modify two assumptions. First, investors (and possibly intermediaries) neglect certain unlikely risks. Second, investors demand securities with safe cash...

The recent revival of Hyman P. Minsky’s ideas among policymakers, economists, bankers, financial institutions, and the mass media, synchronized with the increasing gravity of the subprime financial crisis, demands a reappraisal of the meaning and scope of the “financial instability...

This paper proposes a practical approach to address the procyclicality of initial margin at central counterparties (CCPs) that can work even in periods of extreme stress. The approach allows CCPs to limit the speed of margin increases resulting from spikes in market volatility. To maintain the...

The present study investigates the possible existence of a systematic relation between beta and excess-return for portfolios of Turkish equities. In the process, no systematic relation is found between beta and realized portfolio excessreturn, in an unconditional sense. However, the study does...
