General Equilibrium Modeling

In special event evaluation, given the shift away from standard economic impact analysis based on input–output modeling, increased attention is being paid to the roles that computable general equilibrium modeling (CGE) and cost–benefit analysis (CBA) can play in event evaluation. This article analyzes the strengths and limitations of CGE and CBA in the context of event assessment. A "hybrid" approach is outlined which includes a role for the advantages of both techniques to be included in the evaluation process. The issues addressed are theoretically important for both impact and benefit estimation, while having significant practical implications for event assessment.

Fdi Effects

Presented paper aims to suggest theoretical framework, application of which would allow indicating if foreign direct investment (FDI) facilitates or hinders economic development of host country economy. Central ideas elaborated in the article are as follows. The first, necessity of cost‐benefit analysis of FDI inflow is emphasized. As state policy favourable for foreign capital means costs, instrument for benefit estimation is required. Neoclassical and industrial organization theories are being employed for FDI effects evaluation purpose. Assumption about changing effect of FDI after medium‐term period of 6–7 year passes has been raised and tested. Data of Lithuanian manufacturing branch and its three main comprising manufacturing sectors for the 1996–2007 period have been employed. Results of application of elaborated theoretical framework lead to corollary about different impact of FDI on various sectors of economy and high probability of diminishing positive initial impact after medium‐term time span passes.

Abstract Reverse osmosis concentrate (ROC) is one of the major drawbacks in membrane treatment technologies specifically due to the scale-forming ions. It is important to remove these ions from ROC to enhance total water recovery and reuse in the textile industry that is the largest water-consumer and polluter industry. In this work, coagulation/high pH precipitation (CP) integrated with ceramic microfiltration (CMF) was studied as a pretreatment method followed by nanofiltration (NF) to increase the efficiency of water recovery. To prevent organic fouling, ferric chloride (FeCl3) was applied at a concentration of 3 mM, and ceramic membranes were used for the removal of non-precipitating crystals and/or suspended solids (at high pH) before the NF processes. The CP-CMF method successfully removed calcium (Ca2+), magnesium (Mg2+), silica (SiO2), and TOC up to 97, 83, 92, and 87% respectively, which resulted in higher performance of the NF process. Moreover, this method provided higher flux at lower pressure that ultimately increased overall water recovery of the NF process to achieve near-zero liquid discharge (n-ZLD). A cost-benefit estimation showed that a high-quality effluent (COD<5 mg/L; conductivity 700<μS/cm; negligible residual color) can be generated and recycled in the textile industry at an economical cost (approximately 0.97 USD/m3). Therefore, ROC minimization and water recovery can help to achieve n-ZLD using CP-CMF/NF method.
