Dynamic effects of externalities,optimal saving and economic growth

Conclusion Recognizing the fact that provision of mixed public goods can result in both consumption externalities of the Samuelsonian variety as well as production externalities we set out to extend the earlier results of Rao and Kalpagam (1977) on the effect of public goods on economic growth. In so doing, we considered three standard specifications of production externalities and enlarged the concept of consumption displacement. Our basic conclusion is that the results of our earlier paper remain valid under the more general conditions set out in this paper.     

Vergleich des verallgemeinerten nichtzentralent-Tests mit dem Binomialtest

Zusammenfassung Es sei {F _,(x); –<<, >0} mitF _,(x)=F((x–)/)–F(x) eine standardisierte Verteilungsfunktion — die Familie der zulässigen Verteilungsfunktionen. Der (früher eingeführte) verallgemeinerte nichtzentralet-Test für die Hypothese {PP ₀} mitP:=F _,(x ₀) gegen die Alternative {P>P ₀} zum Niveau wird mit dem entsprechenden nichtparametrischen Test (Test für die Hypothese {pP ₀} über den Parameterp einer Binomialverteilung gegen die Alternative {p>P ₀}) verglichen. Für dent-Test wird die relative asymptotische Effizienz bestimmt.Beide Tests lassen sich als Tests für das zur WahrscheinlichkeitP ₀ gehörende Quantil einer Verteilungsfunktion interpretieren. Der klassische zentrale Student-Test ergibt sich als Spezialfall (F(x)=(x),P ₀=0,5).

Summary Let {F _,(x);–<<, >0} withF _,(x ₀):=F((x–)/–F(x) a standarized distribution function — the family of admissible distribution functions. The (earlier introduced) generalized noncentralt-test for the hypothesis {PP ₀} withP:=F _,(x ₀) against the alternative {P>P ₀} at level of significance is compared with the corresponding nonparametric test (Binomial test). The relative asymptotic efficiency of thet-test is determined. Both kinds of tests can be interpreted as quantiltests. In caseF(x)=(x),P ₀=0,5 one gets the classical central Student-test.

     

Innovative human resource management and corporate performance in the context of economic liberalization in India

The Indian economy was forced to adopt a structural adjustment programme at the beginning of 1991. The structural adjustment programme or liberalization initiated the process of the opening up of an otherwise closed economy of India. Liberalization created a hyper-competitive environment and to respond to this turbulence, Indian organizations adopted innovative changes in their HRM practices. Current research shows that HRM practices are important for enhanced corporate performance but little has been reported on the effect of HRM practices and corporate performance in the context of economic liberalization of India. This study tries to understand the role of innovative HRM practices and specifically questions how HRM practices, such as the role of HR department, recruitment, retraining and redeployment, performance appraisal and compensation, enhance corporate performance during the change process. A multiple-respondent survey of 69 Indian organizations was undertaken to study the impact of innovative HRM practices on firm performance. The survey found that the innovative recruitment and compensation practices have a positive significant relationship with firm performance. It was observed that recruitment, the role of the HR department and compensation practices seem to be significantly changing within the Indian firms in the context of India's economic liberalization. The synergy between innovative HRM practices was not significant in enhancing corporate performance during the liberalization process.     

A theory of gender differences in parental altruism

Abstract.  We offer a theory of gender differences in parental altruism based on the asymmetry that female fertility is constrained but male fertility is relatively unconstrained. Modelling human preferences as having been shaped during the Pleistocene, we derive evolutionarily stable, co‐evolved male and female preferences for altruism towards one's children. We demonstrate that there would be gender differences in parental altruism that depend on the relative abundance or scarcity of resources and the importance and substitutability of parental inputs in promoting the survival of offspring. The results point to greater altruism in females, under plausible conditions. JEL Classification: D64, J16, P46     

Stock returns and economic activity: the UK case

This paper investigates the relationships between real stock returns and a number of financial and economic variables for the UK economy for the period 1980 to 1994. We begin by discussing a theoretical model proposed by Balvers et al. and then re-estimate for the UK what may be regarded as an application of that model by Fama applied to the US market. This reproduces Fama's main results. For the UK we than suggest a slightly, different application of the Balvers model, the most important feature of which is the use of expectational macro-economic variables instead of Fama's use of leading values of industrial production. We then go on to investigate the unit root properties of the data and show that much of the data is indeed characterized by the presence of unit root non stationarity In the light of this, we propose an application of the Phillips-Loretan error-correction model and show that this provides a plausible relationship between real stock returns and most of the financial and economic variables.
