In this paper, the dynamics of Standard and Poor's 500 (S&P 500) stock price index is analysed within a time-frequency framework over a monthly period 1791:08-2015:05. Using the Empirical Mode Decomposition technique, the S&P 500 stock price index is divided into different frequencies known as...

This paper examines the nature and the length of economic adjustments to selected structural reforms, drawing on a variety of approaches: descriptive analysis and simulations using Dynamic General Equilibrium and macro-economic neo-Keynesian models. The descriptive analysis suggests that the...

Long memory in the volatility of individual return series and in the volatility of equal-weighted portfolios constituted by the individual return series is analyzed to see if the memory characteristic of the volatility representation is correlated with the portfolio characteristics of size,...

This paper examines market developments in venture capital and buyout investment in Europe and the United States, through the analysis of funds raised, investments and exits. It discusses the profitability differential of European venture capital investment in comparison with the United States...

We study common determinants of daily bid-ask spreads and trading volume for the bond and stock markets over the 1991-98 period. We find that spread changes in one market are affected by lagged spread and volume changes in both markets. Further, spread and volume changes are predictable to a...

This paper explores liquidity movements in stock and Treasury bond markets over a period of more than 1800 trading days. Cross-market dynamics in liquidity are documented by estimating a vector autoregressive model for liquidity (that is, bid-ask spreads and depth), returns, volatility, and...

Density forecasts have become quite important in economics and finance. For example, such forecasts play a central role in modern financial risk management techniques like Value at Risk. This paper suggests a regression based density forecast evaluation framework as a simple alternative to other...

This paper explores liquidity spillovers in market-capitalization-based portfolios of NYSE stocks. Return, volatility, and liquidity dynamics across the small- and large-cap sectors are modeled by way of a vector autoregression model, using data that spans more than 3,000 trading days. We find...
