Condition-based maintenance using the inverse Gaussian degradation model
Chen, Nan; Ye, Zhi-Sheng; Xiang, Yisha; Zhang, Linmiao - In: European Journal of Operational Research 243 (2015) 1, pp. 190-199
Condition-based maintenance has been proven effective in reducing unexpected failures with minimum operational costs. This study considers an optimal condition-based replacement policy with optimal inspection interval when the degradation conforms to an inverse Gaussian process with random...

On inflation as a regressive consumption tax
Erosa, Andrés; Ventura, Gustavo - 2000
Evidence on the portfolio holdings and transaction patterns of households suggests that the burden of inflation is not evenly distributed. We build a monetary growth model consistent with key features of cross- sectional household data and use this framework to study the distributional impact of...

Is there an environmental benefit to being an exporter? Evidence from firm level data
Batrakova, Svetlana; Davies, Ronald B. - 2010
One of the greatest concerns over globalisation is its impact on the environment. This paper contributes to this debate by analysing the consequences of becoming an exporter on a firm's energy consumption. We show both theoretically and empirically that for low fuel intensity firms exporting...

Estimating a semi-parametric duration model without specifying heterogeneity
Hausman, Jerry A.; Woutersen, Tiemen M. - 2005
This paper presents a new estimator for the mixed proportional hazard model that allows for a nonparametric baseline hazard and time-varying regressors. In particular, this paper allows for discrete measurement of the durations as happens often in practice. The integrated baseline hazard and all...

Unbundling technology adoption and tfp at the firm level: Do intangibles matter?
Battisti, Michele; Belloc, Filippo; Del Gatto, Massimo - 2012
We use a panel of European firms to investigate the relationship between intangible assets and productivity. We disentangle between tfp and technology adoption, while available studies so far have considered only a notion of productivity conflating the two effects. To this aim, we estimate...

Inefficient or just different? Effects of heterogeneity on bank efficiency scores
Bos, Jaap W. B.; Heid, Frank; Koetter, Michael; Kolari, … - 2005
In this paper, we show the importance of accounting for heterogeneity among sample firms in stochastic frontier … assumptions regarding the nature of heterogeneity can be modeled and the extent to which the respective empirical specifications … studies in particular should account for heterogeneity across sample firms. Especially when efficiency measures are employed …
