Estimating Persistence in the Volatility of Asset Returns with Signal Plus Noise Models

This paper examines the degree of persistence in the volatility of financial time series using a Long Memory Stochastic Volatility (LMSV) model. Specifically, it employs a Gaussian semiparametric (or local Whittle) estimator of the memory parameter, based on the frequency domain, proposed by Robinson (1995a), and shown by Arteche (2004) to be consistent and asymptotically normal in the context of signal ...

Structuring International Financial Support for Climate Change Mitigation in Developing Countries

In the Copenhagen Accord of December 2009, developed countries agreed to provide start-up finance for adaptation in developing countries and expressed the ambition to scale this up to $100 billion per year by 2020. The financial mechanisms to deliver this support have to be tailored to country and sector specific needs so as to enable domestic policy processes and self sustaining business models, and ...

Long Memory and Volatility Dynamics in the US Dollar Exchange Rate

This paper focuses on nominal exchange rates, specifically the US dollar rate vis-à-vis the Euro and the Japanese Yen at a daily frequency. We model both absolute values of returns and squared returns using long-memory techniques, being particularly interested in volatility modelling and forecasting given their importance for FOREX dealers. Compared with previous studies using a standard fractional ...

Global and Regional Spillovers in Emerging Stock Markets: A Multivariate GARCH-in-Mean Analysis

This paper examines global (mature market) and regional (emerging market) spillovers in local emerging stock markets. Tri-variate VAR GARCH(1,1)-in-mean models are estimated for 41 emerging market economies (EMEs) in Asia, Europe, Latin America, and the Middle East. The models capture a range of possible transmission channels: spillovers in mean returns, volatility, and cross-market GARCH-in-mean effects. ...

Real Convergence, Capital Flows, and Competitiveness in Central and Eastern Europe

The paper scrutinizes the role of wages and capital flows for competitiveness in the new EU member states in the context of real convergence. For this purpose it extends the seminal Balassa-Samuelson model by international capital markets. The augmented Balassa-Samuelson model is linked to the monetary overinvestment theories of Wicksell and Hayek in order to trace cyclical deviations of real exchange ...

Financial Development and Economic Growth: Evidence from Ten New EU Members

This paper reviews the main features of the banking and financial sector in ten new EU members, and then examines the relationship between financial development and economic growth in these countries by estimating a dynamic panel model over the period 1994-2007. The evidence suggests that the stock and credit markets are still underdeveloped in these economies, and that their contribution to economic ...

Evaluating Greek Equity Funds Using Data Envelopment Analysis

This study assesses the relative performance of Greek equity funds employing a non-parametric method, specifically Data Envelopment Analysis (DEA). Using an original sample of cost and operational attributes we explore the effect of each variable on funds' operational efficiency for an oligopolistic and bank-dominated fund industry. Our results have significant implications for the investors' fund ...

Volatility Spillovers and Contagion from Mature to Emerging Stock Markets

This paper examines volatility spillovers from mature to emerging stock markets and tests for changes in the transmission mechanism-contagion-during turbulences in mature markets. Tri-variate GARCH-BEKK models of returns in global (mature), regional, and local markets are estimated for 41 emerging market economies (EMEs), with a dummy capturing parameter shifts during turbulent episodes. LR tests suggest ...

How Does European Integration Affect the European Stock Markets?

This paper examines the integration of stock markets in Germany, France, Netherlands, Ireland and UK over January 1973-August 2008 at the aggregate market and industry level considering the following industries: basic materials, consumer goods, industrials, consumer services, health care and financials. The analysis is carried out by using correlation analysis, ß-convergence and s-convergence methods. ...
