Item Bezdzietność w Polsce(Wydział Prawa i Administracji UAM, 1981) Vielrose, EgonChildlessness is analyzed among married women aged 35 - 39 in 1970. A strong relationship was found between the proportion of childless women and the gross reproduction rate with a time-lag of 10 years. The respective regression equation seems, however not to be stable in time. The proportion of married women aged 30 - 34 having no children below age 16 might also serve to estimate the proportion of childless women.Item Dochody w Nigerii według wysokości(Wydział Prawa i Administracji UAM, 1975) Vielrose, EgonThe author has analysed the level and distribution of personal income. I. e. he has stated that the coefficient of income concentration amounts to 0,47; in the urban and rural areas, however, the coefficient mentioned is silightly lower.Item Mikro- i makroekonomiczne funkcje produkcji(Wydział Prawa i Administracji UAM, 1968) Vielrose, EgonThere exist both micro- and macroeconomic production functions. Microecoinomic functions concern individual firms whereas macroeconornic functions are valid e.g. for whole industries or branches of national economy. On the basis of suitably chosen numerical examples it is shown that the usual aggregation procedure by summing sometimes leads to nonsensical, or heavily biased results. By performing the same computations on data for average firms better results are obtained. If we use the Cobb-Douglas production function, aggregation must be multiplicative and thus geometric means are appropriate It can be shown, however, that, if the dispersion of the variables involved is small and the respective measures are approximately equal, then arithmetic instead of geometric means can be used. An attempt is made to evaluate production functions for certain industries in Poland in 1965 on the basis of data concerning average firmis in 22 territorial units (voivodships). In order to use the available data certain assumptions have to be made. If these assumptions are confirmed the goodness of fit must be very satisfactory. Thus it seems very plausible that a good fit proves the assumption to be confirmed. The goodness of fit is measured by coefficients of determination. The attempt has proved successful, as is shown by the values of the coefficients of determination which, in some instances, are very close to unity. On the base of these results characteristic features of particular industries are discussed.Item Podatki w krajach rozwijających się(Wydział Prawa i Administracji UAM, 1969) Vielrose, EgonThe aim of the author's article was to examine the role of taxes in the developing countries, to assess the maximum of tax encumbrance possible to realize and to analyse the tax structure. The results of his examination are as follows: 1. As the welfare arises, the importance of tax income generally increases in comparison with the gross social product. 2. Maximum encumbrance with taxes possible to realize oscillates from 10% of gross social product for the poorest countries to 25% for the developing countries on the medium level of welfare. 3. As the welfare arises, the significance of direct taxes generally increases, especially of taxes collected from the people, on the other hand the participation of indirect taxes is growing small.Item Przymusowe oszczędzanie a handel zagraniczny(Wydział Prawa i Administracji UAM, 1969) Vielrose, EgonIn the article a measure of forced savings is derived and methods for ascertaining the presence of forced savings are given. The simplest of these methods uses data concerning the balance of external trade. It is shown that this method can be very useful and leads to valid conclusions even for developing countries with poor official statistics. The interdependence of forced savings and other economic factors and processes is analysed. It is shown that forced savings occur more often in wealthier countries than in poor ones. Moreover forced savings are in general of short duration and are influenced by changes in current government expenditure to a higher degree than by changes in investments.
