Long memory (long-term dependence) of volatility counts as one of the ubiquitous stylized facts of financial data. Inspired by the long memory property, multifractal processes have recently been introduced as a new tool for modeling financial time series. In this paper, we propose a parsimonious...

The KOSPI 200 options are one of the most actively traded derivatives in the world. This paper empirically examines (a) the statistical properties of the Korea's representative implied volatility index (VKOSPI) derived from the KOSPI 200 options and (b) macroeconomic and financial variables that...

This Kiel Policy Brief demonstrates the calculation of a new stock market index informing about the price competitiveness of a country's assets vis-à-vis its foreign competitors. In line with the portfolio balance approach we empirically identify net foreign holdings of a country's assets as...

This heterogeneous interacting agents model of a financial market is a generalization of the model proposed by Westerhoff (The Use of Agent-Based Financial Market Models to Test the Effectiveness of Regulatory Policies) by traders who are allowed to have different investment horizons as...

Daily financial market returns (as log difference in closing prices) may be quite sensitive to operations with low trading volumes and big changes in prices frequently traded at market closing times. This paper proposes a more robust estimation of market, returns by providing a new indicator...

Developing countries are constrained in financing current account deficits as real capital mobility is still far from perfect. At the same time, capital flows to these countries proved to be extremely volatile. The paper argues that the long-term problem of "too little" should not be confused...

We analyze the stock prices of the S&P market from 1987 to 2012 with the covariance matrix of the firm returns determined in time windows of several years. The eigenvector belonging to the leading eigenvalue (market) exhibits in its long term time dependence a phase transition with an order...
