In countries with relatively small firms, entrepreneurial morality is determined by the influences that shape the values, the personality and the character of entrepreneurs as owners and managers of their enterprises. To shed some light on the processes involved we estimate an ordered probit...

It is ascertained that the theorem of proportionality, which maintains that replacement investment is a constant proportion of the outstanding capital stock, has several fundamental shortcomings. It derives from a model founded on assumptions that are highly restrictive and unlikely to hold in...

The models Feldstein and Rothschild (1974) and Jorgenson (1974) adopted to highlight the nature of the replacement ratio were identical. Yet, even though the theorems they derived from them were complementary and reinforced each other, the authors reached diametrically opposite conclusions....

This paper analyzes and compares two alternative policies of determining the service life and replacement demand for vintage equipment under embodied technological change. The policies are the infinite-horizon replacement and the transitory replacement ending with scrapping. The corresponding...

Our objective here is to establish the proposition that creative entrepreneurship gives rise to a market order which is optimally adjusted to facilitate the introduction and the diffusion of innovations, particularly those that take the form of new markets, new organizational schemes, new...

The received theory of aggregation has been erected on certain fundamental hypotheses. One of them is that producer durables deteriorate exponentially, which implies that their replace-ment is proportional to the corresponding capital stocks. However the proportionality hypothesis conflicts with...

This paper investigates the effects of uncertainty emanating from technological im-provements on the optimal lifetime of assets. In does so in a dynamic model in which: a) technological change increases continuously the productivity of producers’ durables, b) po-tential competition induces...

Our objective in this paper is threefold. First, to identify the major common shocks that hit these countries upon entry into the EMU. Second, taking Greece as our case study, to construct a simple macroeconomic model of the policies Greek governments pursued in the presence of these shocks, and...

The economic and social progress Greece achieved in the early post war decades decelerated after 1974 because all institutions sustaining the effi-cient operation of democracy and free markets were deliberately and gravely eroded. Under the impetus of hard core socialists provisions introduced...

The efforts to alleviate poverty by increasing social budgets have failed everywhere in the world and now the question is what else can be done to support those that are left behind. In this paper we search for illumination in the approaches to education that Athens and Sparta adopted in the...
