Fertility pattern of Muslim Hausa women in northern Nigeria

This paper reports the results of a fertility survey conducted in 1980 in Malumfashi town in northern Nigeria. The study covered 302 Hausa-speaking households in 2 wards. Of the 302 married males surveyed, 168 were monogamous, 92 had 2 wives, 30 had 3 wives, and 12 and 4 wives (the maximum allowable). All 168 monogramous marriages were not monogamous at the start. The average duration of present marriage among respondents was 14.1 years for monogamous unions and 11.0 years for polygymous unions. The average number of children ever born to women over 45 years of age was 6.3 (6.7 in monogamous unions and 6.0 in polygamous unions). The average family size for all marriages was 3.6, but this value was 4.6 in monogamous unions and 3.4 in polygamous unions (age standardized values were 4.5 and 3.4, respectively). There were 80 live births in the survey sample during the 12 months preceding the study, with a mean age at childbirth of 28.7 years. The crude birth rate for the surveyed population was 48.06/1000 (46/1000 for monogamous families and 43/1000 for polygamous families). The infant mortality rate was 137.5/1000 live births. About 11% of women in the sample were sterile. The fertility rate observed in this study is lower than that in Nigeria as a whole, perhaps because of the prevalence of polygamous unions in this region. These results support the observation that women in polygamous unions have lower fertility than those in monogamous unions.     

Board structure and role of monitoring committees

Regulators and researchers alike have focused significant attention on the structure of the corporate board. In general, the results of prior empirical studies suggest that larger boards are costly to firms because of communication and co-ordination problems. How firms use committees to mitigate these costs, however, has not received as much attention. Since boards delegate authority for specific tasks to monitoring committees with independent directors, we re-examine the impact of board structure on firm performance by specifically focusing on the number of monitoring committees. Using ROA and EVA, we find that board size is positively associated with firm performance when firms use more than three monitoring committees. We also find that the previously documented negative association between board size and Tobin's Q disappears when a firm uses more than three monitoring committees. Overall, the results suggest that firms use monitoring committees to mitigate the costs associated with larger boards.     

Development of Research in Experimental Design in India

Le travail accompli dans ce cadre est considérable, tant par le volume que par l'importance des contributions, et nous nous sommes attachés à en présenter un historique cohérent. Les sujets traités incluent les carrés latins mutuellement orthogonaux, les plans en blocs incomplets, les plans factoriels, les plans factoriels fractionnaires, les surfaces de réponse, les plans mixtes, les plans ligne‐colonne et les études croisées.     

Religiosity and consumers' use of product information source among Korean consumers: an exploratory research

In response to the lack of research on the impact of religion on consumer behaviour, this study investigates how consumers' use of various product information sources can differ depending on their levels of religiosity (high, low and none). Data were collected from Korean consumers in Korea. The findings from data analyses indicate that the usages of product information sources among Korean consumers generally vary based upon their levels of religiosity. Limitations and suggestions for future research to further understand the effects of religiosity on consumer behaviour were addressed.     

Piracy or promotion? The impact of broadband Internet penetration on DVD sales

The Internet provides copyright holders with new sales and promotional channels for their content, while also providing consumers with new opportunities to illegally obtain free copies of this content. Unfortunately, disentangling these two effects is extremely difficult.In this paper we attempt to disentangle these two effects by applying fixed effects and first difference models to a new dataset quantifying changes in broadband Internet penetration and DVD sales at a local level from 2000 to 2003. We then compare our results to those reported in Liebowitz (2008), who uses similar models in a similar time period on a similar product category: music CDs.Unlike Liebowitz, who finds a strong negative impact of broadband penetration on music sales, our results show that increased broadband penetration leads to a significant increase in DVD sales. Using the most conservative results, 9.3% of the $14.1 billion increase in DVD sales during our study period can be attributed to increased broadband penetration. One interpretation of these results is that the difference arises from differences in the ability to pirate these two types of content: while Internet music piracy was easy and rampant from 2000 to 2003, Internet movie piracy was difficult and of generally low quality in this time period. If this interpretation is true it would suggest that, in the absence of piracy, the Internet has an overall strong positive impact on media sales.     

Can total factor productivity explain value added growth in services?

This paper examines the factors responsible for generating the services led growth witnessed in the Indian economy during 1980–2005. A sectoral growth accounting exercise shows that total factor productivity (TFP) growth was the fastest for services; moreover this TFP increase was significant in accounting for service sector value added growth. A growth model with agriculture, industry and services as three principal sectors is calibrated to Indian data using sectoral TFP growth rates. The baseline model performs well in accounting for the evolution of value added shares and their growth rates, but is unable to capture sectoral employment share trends. The performance of the model with respect to value added shares improves when the post 1991 increase in service sector TFP growth following the inception of market-based liberalization reforms is accounted for. A modified version of the model with public capital can better track trends in sectoral employment shares.     

Joint governance in North American workplaces: a glimpse of the future or the end of an era?

North American innovations in joint governance (such as Saturn, NUMMI, Xerox, and Shell Sarnia), though limited in number, have drawn world-wide attention from line and staff practitioners, as well as policy makers. These voluntary initiatives in unionized North American settings stand as an important counterpoint to two alternative forms of innovation – legislated forms of joint governance such as European works councils and non-union high-commitment systems that are most common in North America. Current debates on workplace governance in North America are implicitly and sometimes explicitly choosing among these three innovative arrangements as alternative ‘ideal types’. This article begins with nine hypotheses on joint governance, which are derived from case-study analysis. The hypotheses focus on the antecedents, dynamics and consequences of joint governance. Together, they can help guide practitioners seeking diffusion of joint governance concepts. The hypotheses can also help guide the construction of public policy on workplace governance. Ultimately, the question remains – are these initiatives a glimpse of the future or do they mark the end of an era?     

Immigration, Race, and Labor: Unionization and Wages in the Canadian Labor Market

In Canada, most racial minorities have lower rates of unionization than do members of the majority workforce. Data from the Survey of Labour and Income Dynamics ( N = 32,634) show that racial minority immigrants assimilate into unionization over time. However, unionization reduces net minority wage disadvantages only slightly. Union race relations policies should place more emphasis on collective bargaining as well as on unionization.
