Factors influencing women's decision to leave an organization following childbirth

The purpose of this study was to understand the reasons why college-educated women leave organizations after childbirth. Results from 228 women who participated in a study of intention to work following childbirth indicated specific work and family factors that differentiated mothers who returned to work from mothers who stayed home after childbirth. Comparisons were also made between women who had a child and those who anticipated having a child. The findings are discussed in terms of their implications for organizational policy makers.     

Towards an understanding of the real effects and costs of inflation

Zusammenfassung Zum Verst?ndnis der realen Wirkungen und Kosten der Inflation. — Die traditionelle Ansicht, da\ eine Inflation, weil Geld neutral ist, keine nennenswerten realen Wirkungen hervorbringt, erweist sich nur für eine Volkswirtschaft als ann?hernd richtig, deren Regelungen vollst?ndig inflationssicher sind, d. h. für eine vollindexierte Wirtschaft. Die Realwirkungen erweisen sich aber als um so verbreiteter und schwererwiegend, je mehr bei wirtschaftlichen Regelungen Nominalwerte verwendet werden. Der Aufsatz untersucht nacheinander die Folgen von amtlichen Regelungen auf Nominalbasis (Steuersystem, Definition des steuerpflichtigen Einkommens, Buchführungsmethoden), von privaten Einrichtungen und übereinkünften auf Nominalbasis (Hypotheken, Rentenvertr?ge, Einkommensberechnungen), selbst für den Fall, da\ die Inflation vollst?ndig antizipiert wird bzw. wurde. Anschlie\end werden die Wirkungen einer nicht antizipierten Inflation geprüft, die in den bestehenden nominalen langfristigen Vertr?gen nicht berücksichtigt worden ist, und die Wirkungen einer Ungewissen zukünftigen Inflation. Soweit es m?glich ist, wird versucht, die sozialen Kosten von verschiedenen Realwirkungen abzusch?tzen, obwohl es zur Zeit nicht m?glich ist, die allgemeinen sozialen Kosten der Inflation zu ermitteln.

Résumé Vers une compréhension des effets réels et des co?t d’inflation. — Nous démontrons que la vue traditionelle d’après laquelle l’inflation ne produit pas des effets réels appréciables à cause de la neutralité d’argent est valide pour une économie seulement dont les institutions sont complètement étanche à l’inflation, c’est-à-dire il s’agit d’une économie indexée. Mais nous démontrons que les effets réels deviennent plus et plus diffusés et sérieux comme les institutions de l’économie deviennent presque plus nominales. L’article examine succédamment les conséquences des institutions nominales de gouvernement (le système fiscal, la définition de revenu taxable, la procédure comptable); des institutions privées nominales et des conventions comptables (les contrats de hypothèque et d’annuité, le mesurage de revenu), même si l’inflation est, et a été complètement anticipée. En plus l’article examine les effets de l’inflation pas anticipée et pas incorporée dans les contrats nominaux existants à long terme, et de l’inflation future incertaine. S’il est possible, nous entreprenons l’effort de fixer les co?t sociaux des effets réels différents même bien qu’il ne soit pas possible au moment présent de fixer tous les co?t sociaux de l’inflation.

Resumen Hacia el entendimiento de los verdaderos efectos y costos de la inflatión. — La visión tradicional que la inflatión no produce efectos reales apreciables debido a que el dinero es neutral, es solamente válida en forma aproximada para una economía cuyas instituciones están completamente a prueba de inflatión, p.ej. una economía completamente indexada. Pero se muestra que los verdaderos efectos se generalizarán más y más y serán más serios en la medida que las instituciones de la economía sean más cercanamente nominales. El artículo examina en forma sucesiva las consecuencias de instituciones gubernamentales nominales (sistema de impuestos, definitión del ingreso imponible, procedimientos contables); de instituciones privadas nominales y convenciones contables (hipotecas y contratos de renta anuales, medición del ingreso), incluso cuando la inflatión es y ha sido totalmente anticipada. Examina en seguida los efectos de inflatión no anticipados, que no han sido incoirporados dentro de los contratos de largo plazo existentes, y de inflatión futura incierta. En los casos que fue posible, se hizo un esfuerzo por determinar el costo social de varios efectos reales, aunque en este momento no es posible apreciar los costos sociales totales de la inflatión.

     

Regional taxonomy : A comparison of some hierarchic and non-hierarchic strategies

The effects of subjective decisions, particularly in the case of regional taxonomic methodology are often underestimated. Therefore the aptitude of alternative methods needs more careful evaluation. Comparisons of competing methods would provide important guidelines. A general evaluative approach based upon the discrepancy between the original resemblance and the derived cophenetic matrix is outlined for the hierarchic regional taxonomic case. Five main aggregative linkage strategies are appraised by means of quantitative measures. Furthermore two iterative non-hierarchic methods are compared for handling non-hierarchic regional taxonomic problems, where particular attention is paid to the influence of different initial partitions upon the (sub) optimal result.     

The effects of dividend yield and dividend policy on common stock prices and returns

This paper suggests that it is not possible to demonstrate, using the best available empirical methods, that the expected returns on high yield common stocks differ from the expected returns on low yield common stocks either before or after taxes. A taxable investor who concentrates his portfolio in low yield securities cannot tell from the data whether he is increasing or decreasing his expected after-tax return by so doing. A tax exempt investor who concentrates his portfolio in high yield securities cannot tell from the data whether he is increasing or decreasing his expected return. We argue that the best method for testing the effects of dividend policy on stock prices is to test the effects of dividend yield on stock returns. Thus the fact that we cannot tell, using the best available methods, what effects dividend yield has on stock returns implies that we cannot tell what effect, if any, a change in dividend policy will have on a corporation's stock price.     

Technology transactions: networks over markets

There is a widespread belief in the business community that firms can rely on the market for buying and selling technological opportunities. The argument is: with so much technology development going on in the world, ‘there must be somebody somewhere who has the technology we need.’ According to this belief, acquiring new technology just boils down to finding the supplier, possibly with the help of a specialized intermediary. Several large firms have indeed developed ambitious mechanisms for acquiring the needed technological know-how as they proceed to make and market a new product. We contend that this concept of the technology transfer process is erroneous, as it conflicts with actual practice. The very high transaction costs entailed leave considerable room for opportunistic behavior and are more likely to occur when the parties do not know each other. An effective way to reduce transaction costs, therefore, is to limit technology transfers to the firm's partners, i.e. organizations with which the firm has already interacted in the past. Our research provides evidence that successful technology transfers typically take place between suppliers and buyers who had business relationships before considering a technology agreement. In addition, we report findings that companies using intermediaries (technological opportunities catalogues, databases, fairs, etc.) have been disappointed in their attempts to find new technologies from unknown sources. Because of the high risk of opportunistic behavior, it is practically impossible to assess the value of a technology without knowing who sells it. Similarly, the technology transfer capabilities of a company are difficult to appraise without prior knowledge through business interaction. To a certain extent, it may be better to buy any technology from a partner that one knows well than to buy a supposedly good technology from a firm with which one has had no experience. To put it bluntly: the identity of the partner may actually matter more than the technology being traded! Consequently, the relevant framework for technology transfer is built on a ‘network concept’ rather than the ‘market concept’. Firms wishing to acquire new technology should turn first to their network of trusted business partners, looking for available technological opportunities instead of trying to buy technology from unrelated organizations.
