Authors: Negakis, Christos J.
Abstract: The efforts to derive a theoretically correct valuation model based on
accounting data has lead to the development of the Feltham and Ohlson
(1995) model, which employs book values (BV) and residual income (RI) as
valuation attributes. However, in empirical settings RI is often replaced by
net income (NI). The present paper shows that replacing RI with NI in valuation
models potentially reduces information content and significance. The
results also indicate that RI has a stronger association with Market values in
conjunction with Research and Development expenditures (RD) and Book
value. RD is shown to enhance the explanatory power of NI and RI for market
values (MV). Its inclusion in valuation models, is thus, supported by the
present paper.2005-01-01T00:00:00ZA time series model for the long-term forecast of ports' container handling : the case of the port of PiraeusEleftherios, ThalassinosVassilis, Michalopoulos/library/oar/handle/123456789/314602018-06-29T01:33:16Z2005-01-01T00:00:00ZTitle: A time series model for the long-term forecast of ports' container handling : the case of the port of Piraeus
Authors: Eleftherios, Thalassinos; Vassilis, Michalopoulos
Abstract: The purpose of this study is to investigate the future demand of ports’ container handling and to propose a model to forecast this demand using annual data from the Piraeus Port Authority for the period 1980 to 2005. The variables used refer to the GDP, the population of the country, the gross investments of fixed capital of the transport sector, the weighted mean of price of container handling, the unemployment rate, the gross domestic product of the maritime transport sector in current prices, and a dummy variable. The empirical evidence refers to the port of Piraeus; the computations were run using the statistical package SAS and the results are consistent with the theory. The proposed methodology may be used for long run forecasts at any other similar situation.2005-01-01T00:00:00ZThe ambiguity of the enterprise resource planning (ERP) : hit or doom?Fafaliou, IreneZervopoulos, Panagiotis/library/oar/handle/123456789/314342018-06-29T01:33:10Z2005-01-01T00:00:00ZTitle: The ambiguity of the enterprise resource planning (ERP) : hit or doom?
Authors: Fafaliou, Irene; Zervopoulos, Panagiotis
Abstract: In the age of the smart machine and informative domination, work organizations
and their managers look forward to acquiring internal advantages
for their companies in response to external changes and pressures. In
this pursuit for success managers are often attracted by various techniques
and software programmes such as reengineering solutions and ERP applications.
However, there is no general agreement on the benefits or misfits of
both of the aforementioned projects in the business literature. This paper
tries to offer a critical analysis of the Business Process Reengineering (BPR)
movement and examines its compatibility with ERP solutions. It is argued
that both managerial innovations are “top-down” approaches and company’s
ability to perform high standards still mainly depends on managerial
heads’ authority. However, as it is revealed out of the majority of case studies
reviewed, ultimately, every effort for business modernization and success
depends on the objectives, interpretation and commitment for change.2005-01-01T00:00:00ZAsymmetric shocks, structural rigidities and adjustment capability in EMU - a reviewTheodoropoulos, Sotirios/library/oar/handle/123456789/314302018-06-29T01:33:17Z2005-01-01T00:00:00ZTitle: Asymmetric shocks, structural rigidities and adjustment capability in EMU - a review
Authors: Theodoropoulos, Sotirios
Abstract: The high degree of sustainable nominal convergence between EMU
member states have not implied a corresponding degree of real and structural
convergence. Still existing structural asymmetries in the monetary union,
which is not an Optimum Currency Area, are bound to broaden due to
continuous enlargement of Europe, giving rise to various kinds of shocks and
divergences, poor economic performance in some member countries and to
Europe as a whole. This paper examines the potential sources of asymmetries,
which to a large extend determine the exposure to asymmetric shocks,
or asymmetrical effects stemming from symmetric shocks. We also analyze
available adjustment mechanisms and appropriate policy instruments in
EMU’s economic reality. Using a set of economic indicators we investigate
how some product and labor market rigidities affect in an adverse way macroeconomic performance in EMU. Having restricted the fiscal room for maneuver under the Stability and Growth Pact, existing asymmetries and structural
rigidities call for a speed-up of structural reforms, as the only way to
growth and prosperity.2005-01-01T00:00:00Z
