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 相似文献
This paper deals with the joint management of operations at the supply hub for the customer and the upstream supplier. Different operating conditions are considered, namely, backordering, minimum and maximum specified inventory levels. Some analytical insights on better managing suppliers operating under a vendor managed inventory program are presented. Essentially, we show that the penalty cost imposed on over- and under-stocking, and the min–max policy for hub inventory reside in the power of the hub operator. The relationship between supply hub policy and performance measures is quite complex and non-linear in nature. We suggest a structured hierarchical approach which can help supply hub in achieving balance between various parties involved in chain. A numerical example and an algorithm are included to highlight this result. 相似文献
This paper examines the effect of trade liberalization on the quality of industrial goods produced by a developing country. The intermediate goods used as inputs to industrial production are assumed to be non-traded and produced by firms with market power. It is shown here that for a certain range of human capital levels, exposure to free trade, instead of resulting in de-industrialization, can raise welfare through an improvement in the quality of domestically produced industrial goods. 相似文献
Large consumer goods firms manage and market an assortment of brands and consistently deal with strategic challenges related to brand portfolio management, such as creating or acquiring brands, growing brand equity, managing brands in the portfolio and deleting brands. There is substantial research on several areas of brand portfolio management except in the area of brand deletion. This situation exists despite the fact that deleting weak brands has important implications for a firm and its brand portfolio. Therefore, it is critical to understand why firms delete brands from their portfolios. This research applies a qualitative approach using semi-structured interviews and thematic analysis in the context of firms that adopt a ‘house of brands’ brand architecture and presents findings guided by the strategic decision-making literature. 相似文献
The effect of proactive environmental strategies (PES) on corporate performance has been debated extensively among academics; however, the significance of the pathway of those strategies—internal green integration (IGI) through greening the supplier (GTS) and environmental collaboration with suppliers (ECS)—remains undecided. This study examines environmental performance (EP) through GTS, IGI, and ECS. It also examines the direct link between PES and IGI. A conceptual framework was designed following a rigorous review of the literature. A survey questionnaire was used to collect cross-sectional data from a random sample of manufacturing firms, obtaining 196 usable samples. Using AMOS, the structural equal modeling found a positive and significant impact of PES on IGI. Significant predictors of EP were GTS, IGI, and ECS. The findings of the study can provide managers with guidelines for dealing with business and environmental concerns. They can also contribute to creating strategies for environmental protection and management and reducing adverse effects on the environment. Finally, by examining the direct links between GTS, ECS, and EP, particularly in a developing context, the study may contribute to the literature of environmental policy. 相似文献
The theoretical association of money supply and exchange rates with prices has been empirically established and shown to be dominant in explaining changes in price levels in India. However, post liberalisation, studies have shown price levels to be impacted by several other factors as also, weakened influence of the traditional factors established by theories. This study aims to find the determinants of price level for the period 1994–2008 using a Vector Autoregression model and test the predictive ability of the model. Our results show shorter and smaller impact of change in money supply and nominal effective exchange rate on price levels. Both money supply and nominal effective exchange rates are found to Granger-cause Consumer Price Index. But, impulse response functions show that the impact of shocks from money supply and nominal effective exchange rates on consumer prices peaks after two lags and is short-lived. Forecast error variance decomposition shows that these demand side factors contribute only 6 % of the forecast error variation in Consumer Price Index.
While there is recognition that market-based capabilities contribute to a firm’s financial performance, the exposition is
largely conceptual (Srivastava et al. Journal of Marketing 62:2–18, 1998; Journal of Marketing 63:168–179, 1999). Using a
resource based view of the firm, the present study proposes that (1) market-based assets and capabilities of a firm impacts
(2) performance in three market-facing business processes (new product development, supply-chain and customer management),
which in turn, influence (3) the firm’s financial performance. It develops related hypotheses and tests the framework empirically.
The study also examines for the first time the interrelationship among the three business processes and their impact on the
market value of firms. Further, the study examines the moderating influence of two organizational variables—size and age of
the firm. Overall, the major contribution of the study is that it offers a process linkage between capabilities, process performance
and financial performance. The results of this research will provide strategic insights to managers on optimal customer management,
product development and supply chain strategies.
ABSTRACTThis study examines the effect of changes in internal control certification requirements (ICCR) on the earnings management choices of Australian firms in the period 2007–2015. The Australian setting is unique as the certification requirements change from voluntary in 2004–2007 to mandatory in 2008–2014, before being abolished in 2015. Consistent with the notion that real earnings management (REM) is less susceptible to detection, the results suggest that firms place greater reliance on REM than on accrual-based earnings management (ABEM) when having to comply with certification requirements. In particular, I find voluntary certifiers have lower REM and ABEM relative to first-time certifiers in the mandatory period between 2008 and 2014, and there is an increase in REM activities among first-time mandatory period certifiers. Moreover, firms that discontinue certification, after the abolition of the requirement in 2015, switch from REM to ABEM. This suggests that regulatory ICCR changes affect firms’ earnings management choices. 相似文献
