Title: Estimation of interregional trade coefficients and multipliers in the context of an interregional model Authors: Valma, Erasmia Abstract: The main purpose of this study is to construct a complete three region interregional input-output model which can be applied as a tool for regional analysis. In addition the model is applying to calculate the interregional trade coefficients and multipliers on the basis of 2010 data for 3 regions and 10 sectors of the Greek economy. The methodology used in this study is based on an interregional analysis of input-output. Besides, the interregional input-output matrix provides a complete description of the relations between industries and regions. In the procedure of estimating the interregional flows and trade coefficients the method of Chenery-Moses model was used. The results obtained show that the multipliers derived in the interregional matrices appear generally realistic. It is important to note that the empirical findings are first presented as well as the constructed interregional model for Greece. So, the construction of an applicable and reliable model was needed to bridge the existing statistical gap. With respect to the research limitations, the input-output analysis presupposes a rigid production technology away of adaptability to a changing environment. This limitation is well known and unavoidable in an input-output model. Concluding, the important characteristic of interregional analysis is to establish a base upon which future projections can be made about the role in driving one region’s economic growth. Therefore, the interregional input-output model reported by this study provides an indication to the policy makers how and which productive sectors have contributed to the growth of the regions.

Title: The effect of freight transport time changes on the performance of manufacturing companies Authors: Sambracos, Evangelos; Ramfu, Irene Abstract: Freight Transport Time (FTT) is an important resource for manufacturing companies, firstly as a cost driver of logistics processes and secondly as a key factor of customer satisfaction. Yet, there is a lot of controversy between researchers regarding the strength of the link between changes in transport time and business performance and the methods used to measure this effect. In this context, the aim of this paper is to estimate the effect that changes in freight transport time have on the economic performance of transport consuming manufacturing companies. With the use of System Dynamics Modelling a simulation model is built identifying the role of FTT in the internal supply chain of a Make to Stock manufacturer. Changes in FTT are introduced in the system affecting the production materials inventory replenishment time and the delivery to consumer time. Simulation results suggest that the effect of FTT changes depend highly on the structure of the company’s decision making process. Through the development and simulation of several scenarios it is evident that information feedback about changes in FTT if interpreted and processed by different decision rules and strategies can lead to different results allowing companies to fruitfully - or not - reap the benefits of improved FTT.

Title: The impact of longevity on health care systems Authors: Mertl, Jan Abstract: Population's ageing and the increasing longevity of life are not spontaneous processes. In reality, it is a society's achievement that people are given a chance to live longer. This state is obviously achieved only when citizens take this opportunity seriously and contribute to the overall conditions with their own interests and behavioral choices. More importantly, with people living longer, the overall picture of the society is changing. It even forces grand financial schemes to change, including the health care one which must comply with societal changes. In this regard we can clearly perceive that some of the aspects that we could have been relying on in the past are becoming obsolete and new concepts emerge, that have to betaken seriously. The paper will be based on the overall picture of determinants and factors that poses longevity on health care systems. Specific situation in the Czech health care system, is assessed and the financing schemes used will be described, including current trends caused by economic downturn. The arguments for maintaining and enhancing schemes of health care financing without individual risk assessment will be discussed and presented to the participants.

Title: Panel data estimation techniques and mark up ratios Authors: Polemis, Michael L. Abstract: The purpose of this paper is to evaluate the market power of the Greek manufacturing and services industry over the period 1970-2007. In particular, the empirical model, estimates the mark-up ratio following the Roeger (1995) methodology, separately for the two industries by using Ordinary Least Squares (OLS) and Two Stage Ordinary Least Squares (TSLS) in two unbalanced panel data sets. The sample comprises a total of 23 and 26 two-digit NACE codes. The empirical results indicate the existence of significant market power in the Greek manufacturing and services industry. Moreover, mark-up ratios vary significantly between the two industries, with services having higher mark ups than manufacturing.
