abstract o ur basic aim in this paper concerns the question that if overusing the information technology by service and manufacturing firms can increase the total productivity resulting from this kind of technology regarding the iran's economic structure and conditions. for this purpose, we primarily evaluate the productivity resulting from the rate of firms' use of it for the differe...

This paper further tests Romer’s (1993) extension of Kydland and Prescott’s (1977) predictions for dynamic-inconsistency problems in open economies. In a panel data set of developed and developing countries from 1973 to 1998, I find that openness does not play a role in restricting inflation in the short-run. On the other hand, a fixed exchange-rate regime plays a significant role. The results ...

This paper estimates the effect of informal care provision on female caregiver’s health. We use data from the German Socio-economic Panel and assess effects up to seven years after care provision. A simulation-based sensitivity analysis scrutinizes the sensitivity of the results with respect to potential deviations from the conditional independence assumption in the regression adjusted matching...

this paper seeks to understand the role of the cost of pollution from vehicles fuel in feasibility of cng national plan. optimal control theory is used with two target functions, one with and another without the cost of pollution. model results indicate the high importance of pollution cost in the project feasibility, in such a way that without consideration of that the project will be infeasib...

High degree of interest sensitivity of durable goods is now a stylized fact in the literature of monetary policy. This literature, however, does not provide a clear and consensual explanation for the modalities of this stylized fact. In this paper, two independent empirical models are performed to shed more light on the cross-sectoral impacts of monetary policy. The results of first study indic...

In this paper the Esscher premium calculation principle is applied to the non-compound collective model in a robust Bayesian context. We consider that uncertainty with regard to the prior distribution can be represented by the assumption that the unknown prior distribution belongs to a class of distributions 0 and examine the ranges of the Bayesian premium when the priors belong to such a class...

In performing Bayesian analysis of a bonus–malus system (BMS) it is normal to choose a parametric structure, π0(λ), in the insurer’s portfolio. According to Bayesian sensitivity analysis the structure function can be modelled by specifying a class Γ of priors instead of a single prior. In this paper, we examine the ranges of the relativities, i.e. δ = E[λπ(λ|data)]/E[λπ(λ)], π ∈ Γ . We illustra...

background: core needle biopsy (cnb) with histological findings is regarded as one of the most important diagnostic measures that make preoperative assessment and planning for appropriate treatment possible. the aim of this study was to determine the sensitivity and specificity of core biopsy results in our patients with benign and malignant breast lumps, especially for borderline breast lesion...
