Farm households diversify their income sources by working off the farm. This is a risk management strategy that is used by farm households in both developed and developing countries. Income diversification via off-farm work is associated with higher incomes and food consumption. However, little is known about the association between off-farm work and farm household food expenditures. In an effort to bridge this gap, this study attempts to assess the impact of off-farm work decisions by the operator and/or the spouse on the food expenditures of the farm household. Using a nationwide farm household survey in the United States and new econometric method, we find that the decisions of the operator and/or the spouse to work off the farm are significantly interrelated (29%). However, these two decisions affect food expenditures in different ways. The operator’s off-farm work decision is positively related to food expenditures, while the spouse’s decision is negatively associated with expenditures on food by the farm household.  相似文献

Participation in government programs has a mild impact on the economic well‐being of U.S. farm households. Major factors that determine farm household prosperity are the primary operator's education level and ethnicity, education level of the spouse, and other characteristics such as forward purchasing of inputs, use of contract shipping of products, having a succession plan, farm ownership, and location in a metro area. This article uses the 2001 Agricultural Resource Management Survey (ARMS) as well as relative and an absolute measure to assess U.S. farm households' economic well‐being. The relative measure compares the income and wealth position of farm households relative to median income and median wealth of the general population. The absolute measure adds annualized wealth to a farm household's income.  相似文献

In R&;D organizations of high tech firms, multiple R&;D projects are executed concurrently and timeliness of project completion - i.e., developing the right products at the right times - is a matter of serious concern. Given that the priority of R&;D projects and the interdependencies between the projects in a high tech firm change dynamically, high tech R&;D project management is a complex and challenging endeavor. To improve the understanding and management of high tech R&;D projects, this paper reports the findings of a field study where we, first, develop and empirically estimate a model that relates project priority over time with the generative mechanisms of market pull and technical challenge associated with R&;D projects. Next, we develop and demonstrate the application of a process model within which the time-varying project priority model is embedded. The process model makes it possible to allocate fixed resources among competing projects with time-varying interdependencies, thereby improving the timeliness of project completion. This research was conducted in collaboration with a major U.S. high tech firm. The corporate R&;D center of the firm served as the research setting for the field study. We present an application of the process model to delineate the evolution of the R&;D organization with the merger of its (technology driven) parent firm with another (market driven) high tech manufacturing firm. The application of the process model generates theoretical insights that are used to develop testable propositions. Implications of the study findings and directions for future research are discussed.  相似文献

Studies of undernutrition in India (and elsewhere) have focused exclusively on interpersonal inequalities, and estimates of the magnitude of inter-group inequalities are unavailable. A focus on “horizontal”, or group-based, inequalities offers vital policy insights that would be lost in an approach based purely on interpersonal inequalities. We therefore apply the group analogues of Atkinson's index and the Gini coefficient to shed light on the disproportionate burden of undernourishment borne by rural and historically vulnerable caste groups. Furthermore, the prominent determinants of inter-group disparities are identified through Blinder–Oaxaca decomposition analysis. The paper calls for explicit targeting of backward castes across the country and improved inter-sectoral collaboration to ensure equitable access to education, health care and water and sanitation, particularly across underdeveloped regions.  相似文献

Short-term financing in a cash-constrained supply chain   总被引:4,自引:0,他引:4  
In this paper we consider a two-level supply chain with a single retailer and a manufacturer, where both the firms are facing financial constraints and can not produce/order their optimal quantity. Our work shows that a lender who finances the manufacturer has a motivation to finance the retailer as well. Motivated by this, we investigate lender's problem of financing both the firms by making a joint decision on the loan amount and comparing it with the case when lender makes independent decision on loan amount for both the firms. Our numerical study indicates that if one of the firms in the supply chain has sufficiently low cash, joint decision (we refer to it as supply chain financing) may be better not only for the lender but for the retailer and manufacturer as well.  相似文献

This paper examines the short‐ and long‐run linkages in pre and post global financial crisis among Middle East and North Africa (MENA) stock markets, between MENA and Chinese stock markets and also between MENA and developed (United States and United Kingdom) stock markets. Results indicate that both long‐run co‐integration relationships and short‐run causal linkages among MENA stock markets increased in post‐crisis than that in pre‐crisis sub‐period. The degree of integration between MENA and Chinese stock markets increased in post‐crisis than pre‐crisis. We also find that the degree of integration between MENA and developed (United States and United Kingdom) stock markets increased in post‐crisis than that in pre‐crisis. The presence of increased linkages among MENA markets, and between MENA and Chinese stock markets and also between MENA and developed (United States and United Kingdom) markets has important implications for portfolio investors and policy makers.  相似文献

This paper surveys the evidence on the effectiveness of monetary transmission in low-income countries. It is hard to come away from this review with much confidence in the strength of monetary transmission in such countries. We distinguish between the “facts on the ground” and “methodological deficiencies” interpretations of the absence of evidence for strong monetary transmission. We suspect that “facts on the ground” are an important part of the story. If this conjecture is correct, the stabilization challenge in developing countries is acute indeed, and identifying the means of enhancing the effectiveness of monetary policy in such countries is an important challenge.  相似文献

Despite the widespread adoption of e-procurement by firms in recent years, academic research examining the mechanisms through which e-procurement applications lead to performance has been scarce. Anecdotal evidence points to numerous situations where companies have failed to harness the potential of e-procurement. In this paper, we argue that online purchase volume and mix flexibilities facilitated by these applications play a significant role in the ability of firms to benefit from e-procurement. We examine this tenet from both an economic as well as a social perspective. We propose that increased online purchase volume flexibility as well as online purchase mix flexibility can be facilitated by two mechanisms – supplier customization as explained by transaction costs perspective, and information sharing between supply chain partners using a social exchange theoretical perspective. The increased purchase volume and mix flexibility in turn leads to better performance along the dimensions of cost, quality, and delivery. We present and test a nuanced perspective where we argue that (i) the effect of supplier customization on both purchase volume and mix flexibilities will be moderated by the frequency of transactions conducted online, and (ii) the effect of information sharing on both purchase volume and mix flexibilities will be moderated by trust in the supplier. We estimate our research model using survey data collected from 130 purchasing and procurement managers. We find strong support for our proposed research model with results indicating that purchase volume and mix flexibilities play a vital mediating role in impacting e-procurement performance. Theoretical and practical implications of the findings are discussed.  相似文献

This paper addresses three important questions. First, what are the trends, levels and sources of income inequality in India? Second, how have been the patterns of income mobility? And finally, exploring the relationship between income mobility and income inequality in the context of India. Results, based on recent India Human Development Survey (IHDS) longitudinal data, advocate that not only is income inequality very high, nonetheless, it has increased – mainly attributable to different income sources – in India. The paper also focused on whether or not this income mobility equalizes longer-term incomes. Results suggest income mobility has resulted in-albeit not robust- equalizing longer-term incomes. Thus, based on imperative findings, the paper suggests, the nature of longer-term well-being is crucial to designing policy interventions to effectively tackle inequality and in this context, economic mobility can be seen as an avenue to long-term equality.  相似文献
