This paper investigates the empirical relevance of different unemployment theories in three major economies, namely the UK, the US and Japan, by estimating the degree of dependence in the unemployment series. Both univariate and multivariate long memory methods are used. The results vary...

Using a sample of fare quotes for non-stop travel from New York to London, this paper investigates the dynamics of offered fares as the departure date nears. We find that the general trend is toward fare increase at an accelerated rate as the departure date approaches. Clear differences in...

This paper analyses monthly hours worked in the US over the sample period 1939m1 - 2011m10 using a cyclical long memory model; this is based on Gegenbauer processes and characterised by autocorrelations decaying to zero cyclically and at a hyperbolic rate along with a spectral density that is...

This paper analyses two well-known features of interest rates, namely their time dependence and their cyclical structure. Specifically, it focuses on the monthly Euribor rate, using monthly data from January 1994 to May 2011. Models based on fractional integration at the long run or zero...

This study examines the long-memory properties of German energy price indices (specifically, import and export prices, as well as producer and consumer prices) for hard coal, lignite, mineral oil and natural gas adopting a fractional integration modelling framework. The analysis is undertaken...

In this paper we use fractional integration techniques to examine the degree of integration of four US stock market indices, namely the Standard and Poor, Dow Jones, Nasdaq and NYSE, at a daily frequency from January 2005 till December 2009. We analyse the weekly structure of the series and...

The paper investigates young firms' choice of capital source. Our theoretical model hypothesizes a positive (negative) relation between riskiness of the project (price of venture capital) and receiving informed equity. We test our predictions by employing a unique data set collected by KfW...

This paper investigates the link between the optimal level of non-financial firms' liquid assets and uncertainty. We develop a partial equilibrium model of precautionary demand for liquid assets showing that firms alter their liquidity ratio in response to changes in either macroeconomic or...

This paper investigates the link between the optimal level of nonfinancial firms' leverage and macroeconomic uncertainty. We develop a structural model of a firm's value maximization problem that predicts that as macroeconomic un-certainty increases the firm will decrease its optimal level of...

This paper investigates the effects of macroeconomic volatility on non-financial firms' cash holding behavior. Using an augmented cash buffer-stock model, we demonstrate that an increase in macroeconomic volatility will cause the cross-sectional distribution of firms' cash-to-asset ratios to...
