We examine the relationships between productivity growth, IT investment and organisational change (Δ<i>O</i>) using UK firm panel data. Consistent with the small number of other micro studies we find (a) IT appears to have high returns in a growth accounting sense when Δ<i>O</i> is omitted; when Δ<i>O</i> is...

This study attempts to measure the inefficiency associated with aggregate investment in a transitional economy. The inefficiency is decomposed into allocative and production inefficiency based on standard production theory. Allocative inefficiency is measured by disequilibrium investment demand....

In this paper we consider GMM based estimation and inference for the panel AR(1) model when the data are persistent and the time dimension of the panel is fixed. We find that the nature of the weak instruments problem of the Arellano-Bond estimator depends on the distributional properties of the...

In this paper we show that the Quasi ML estimation method yields consistent Random and Fixed Effects estimators for the autoregression parameter ρ in the panel AR(1) model with arbitrary initial conditions even when the errors are drawn from heterogenous distributions. We compare both...

Instrumental variable estimation is central to econometric analysis and has justifiably been receiving considerable and consistent attention in the literature in the past. Recent developments have focused on cases where instruments are either weak, in terms of correlations with the endogenous...

This paper proposes and discusses an instrumental variable estimator that can be of particular relevance when many instruments are available. Intuition and recent work (see, e.g., Hahn (2002)) suggest that parsimonious devices used in the construction of the final instruments, may provide...

In this paper we consider inference procedures for two types of dynamic linear panel data models with fixed effects. First, we show that the closure of the stationary ARMA panel model with fixed effects can be consistently estimated by the First Difference Maximum Likelihood Estimator and we...

We attempt to replicate for the UK the Corrado, Hulten and Sichel (2005, 2006) work on spending on intangible assets in the US. Their work suggests private sector expenditure (investment) on intangibles is about 13% (11%) of US GDP 1998-2000, with intangible investment about equal to tangible...

The prime task of modelling cross-market contagion is to predict the imminence of a pestilent currency crisis. Empirical models are developed here to study the roles and channels of contagion in exchange rate volatilities, in ways which are as economically sound and econometrically simple as...

It is widely believed that seriously excess debt problems form a major cause of the 1997 Asian financial crisis. This paper investigates empirically the role of the debt problems with respect to both the won/$US rate fluctuations and the won collapse in November 1997. The problems are...
