Design/methodology/approach-For achieving these research objectives econometric models of output are constructed, using firm-level data from Greek companies, which have been collected through a survey through a structured questionnaire. These econometric models are based on the microeconomic production theory (Cobb Douglas production function). For operationalizing the "generalized competition" an organization faces are used the five dimensions of the generalized competition of M. Porter's "five forces framework". Findings-Concerning the above generalized competition dimensions it is concluded that higher level of bargaining power of suppliers results in higher ICT business value generation. Also, concerning strategy it is concluded that in organizations following a strategy of frequent introduction of new innovative products and services is generated higher ICT business value. Originality/value-This paper investigates the effect of external environment related factors on the business value generated by ICT investment. The conclusions constitute of first evidence that there are external conditions that result in higher business value from ICT investment by necessitating a more efficient and effective use of ICT.

This is the first analysis ever of the financial accounts of big business in Greek industry during this historical period. Firstly, we examine through descriptive statistics the trends in basic indicators (and ratios for assets, profits, leverage, liquidity, solvency, and efficiency) during the decade 1927-1936. Secondly, on the basis of panel data analysis we test for differences before (1927-1929), during (1930-1933) and after (1934-1936) the crisis and search for those financial characteristics that allowed certain firms within our survivor cohort to perform better than others during the period under review. The main findings are that: 1) The Great Depression had a rather mild impact on the performance of big business in industry. 2) The level of levera...

The 1870s were marked by: the first bubble in the Athens Stock Exchange(1872/3); a growing involvement of diaspora entrepreneurship in business in Greece (1871+) which became even more pronounced with the post 1879 massive foreign capital inflows and the expansion of industries which served the public at large, such as railways. We argue that this decade was also a watershed relating to corporate governance.

Porter's 'Five Forces Model' of competition, consists of the bargaining power of its suppliers, the bargaining power of its buyers, the competitive rivalry from its competitors, the threat of new entrants and the threat of substitute products or services, and ii) the strategy the organization follows for responding to pressures of its external environment, on the business value generated by ICT investment. The study is based on firm-level data from Greek companies, which have been collected through a survey using a structured questionnaire in cooperation with ICAP, one of the largest business information and consulting companies of Greece. Using these data are constructed econometric models of output, based on the microeconomic production theory, and in particular on the Cobb Douglas production function. From these models concerning the above generalized competition dimensions it is concluded that higher level of bargaining power of suppliers results in higher ICT business value. Also concerning strategy it is concluded that organizations following a strategy of frequent introduction of new innovative products and services enjoy higher ICT business value.
