In this paper we use Monte Carlo simulation to investigate the impact of effect size heterogeneity on the results of a meta-analysis. Specifically, we address the small sample behaviour of the OLS, the fixed effects regression and the mixed effects meta-estimators under three alternative...

Meta-analysis is a research method to synthesise previously obtained researchresults. It is best seen as a statistical approach towards reviewing and summarising theliterature. This paper aims to introduce and critically review the research method ofmeta-analysis and to illustrate its potential...

The empirical economic growth literature is criticized for its lack ofrobustness. For different definitions of robustness, conclusions vary from 'almost everycorrelation is fragile' to 'a substantial number of explanatory variables are robust.' Were-analyze the empirical results of the economic...

This paper analyses the effect of uncertainty on investment spending. We analyse two types of investment, i.e. aggregate investment and investment in energy saving technologies, using subjective evaluations of expectations and uncertainty of Dutch firms in 1997. We estimate several models...

In non-experimental sciences the errors associated with model misspecifications in primarystudies carry over to meta-analysis. We use Monte Carlo simulations to analyse the effects ofthese misspecifications on results of a meta-analysis using a meta-estimator that calculates asimple average...

This paper presents results of a meta-regression analysis on empirical estimates of capital-energy substitution. Theoretically it is clear that a distinction should be made between Morishima substitution elasticities and cross-price elasticities. The former represent purely technical...
