Agroindustrialization through institutional innovation Transaction costs, cooperatives and milk-market development in the east-African highlands 总被引:2,自引:0,他引:2
Garth Holloway Charles Nicholson Chris Delgado Steve Staal Simeon Ehui 《Agricultural Economics》2000,23(3):279-288
Some small-holders are able to generate reliable and substantial income flows through small-scale dairy production for the local market; for others, a set of unique transaction costs hinders participation. Cooperative selling institutions are potential catalysts for mitigating these costs, stimulating entry into the market, and promoting growth in rural communities. Trends in cooperative organization in east-African dairy are evaluated. Empirical work focuses on alternative techniques for effecting participation among a representative sample of peri-urban milk producers in the Ethiopian highlands. The variables considered are a modern production practice (cross-bred cow use), a traditional production practice (indigenous-cow use), three intellectual-capital-forming variables (experience, education, and extension), and the provision of infrastructure (as measured by time to transport milk to market). A Tobit analysis of marketable surplus generates precise estimates of non-participants' 'distances' to market and their reservation levels of the covariates — measures of the inputs necessary to sustain and enhance the market. Policy implications focus on the availability of cross-bred stock and the level of market infrastructure, both of which have marked effects on participation, the velocity of transactions in the local community and, inevitably, the social returns to agroindustrialization. 相似文献

This article presents a policy research agenda for the promotion of farm/non‐farm linkages in South Africa. Our premise is that promoting the participation of small farms and small agroindustrial businesses in these linkages will have a strong impact on employment and income for the poor. We argue that there is potential for growth in linkages. The first question of the policy research agenda concerns the current status of linkages, and we note the dearth of research on this. The second question concerns the constraints on and prospects for promoting linkages from the demand side, and the third question treats the same concerns from the supply side. The fourth question is rooted in the duality in South Africa's non‐farm and farm sectors, and asks whether, and how, small and large agroindustrial businesses and farms will compete or relate in ‘business linkages’ that can benefit intersectoral linkages. The final question concerns the impacts of and alternatives for policies and programmes to spur linkages. 相似文献

The emerging concern about software piracy and illegal or unauthorized use of information technology and software has been
evident in the media and open literature for the last few years. In the course of conducting their academic assignments, the
authors began to compare observations from classroom experiences related to ethics in the use of software and information
technology and systems. Qualitatively and anecdotally, it appeared that many if not most, students had misconceptions about
what represented ethical and unethical behaviors in these realms. Clearly, one can argue that if college students are uncertain
about what constitutes appropriate and inappropriate behavior then this uncertainty will be carried forward into their workplaces
upon graduation. Furthermore, if their workplaces don't provide ethics training as a component of a new employee orientation
program, one can project a potential for unintentional violations and infringements of copyrights and law in the field. This
study was conducted among graduate and undergraduate students to gain insight into their attitudes, perceptions and understanding
of some of the relevant ethics issues. A questionnaire of 11 statements was employed that described ubiquitous but most likely
unethical (or surely dubious) behaviors in the prevailing business and academic environments. Each respondent was asked to
evaluate each statement twice (once for “self” and once for “colleague”) on a five-option highly ethical (5) to neutral (3)
to highly unethical (1) scale. The statements were worded such that lower instrument score was associated with higher ethical
responses. The questionnaire's two-part structure was designed to solicit honest answers. The encouraging learning from this
study was that the overall sample and its various sub-samples did not consider any of the eleven behaviors to be “ethical”
or “highly ethical.” It was also encouraging to note that the overall sample and all sub-samples considered “highly unethical”
those behaviors associated with personal privacy or property or outright theft. This indicated that moral judgment and probity
prevail. The discouraging learning was that behaviors associated with the use of enterprise property were viewed as “neutral”
i.e., neither “ethical” nor “unethical.” These findings suggested confusion and lack of clarity and definition around workplace
deportment as it regards ethics in software and information technology use. The current study suggests that additional research
needs to be conducted to define and clarify the issues, which in turn can form the basis for programs to rectify or at least
ameliorate the situation. 相似文献

The temporal nature of growth determinants in new bank foundings: implications for new venture research design 总被引:1,自引:0,他引:1
Several authors have suggested the founding period as a critical time in the development of a firm, arguing that the resource and decision choices made at this point have a substantive impact on the firm's future. Yet, historically, most studies have measured new venture choices considerably after the founding period. We suggest that the uniqueness of the founding event is important and test its validity through the examination of two implicit assertions. These implicit assertions are those of temporal stability and temporal locus of growth determinants. 相似文献

Market access by smallholder farmers in Malawi: implications for technology adoption,agricultural productivity and crop income 总被引:1,自引:0,他引:1
In Malawi, maize is the major crop and food staple. Given limited off-farm employment opportunities, much-needed increases in household income for improving food security must come from gains in agricultural productivity through better technology and more profitable crops. In the past, hybrid maize and more recently, tobacco were promoted by policy for increasing smallholder income. An analysis of determinants of adoption of these two crops and related income effects is presented. Apart from factor endowment and exposure to agroecological risks, differences in the household's access to financial and commodity markets significantly influence its cropping shares and farm income. 相似文献

The objective of the paper is to study markets in which the value of the activity to any one person increases with the level with which the activity is undertaken by others. The general interpretation could be fads, mimicking behavior, or some sort of belief formation process in which the beliefs or expectations of agents about some underlying state of nature are influenced by the buying behavior of other agents. The result is to create a market that can be modeled as having an upward-sloping market demand curve. The questions posed are (i) in the fad-like environment, does the classical concept of equilibrium (as an equating of market demand and market supply) accurately predict market behavior; (ii) can both stable and unstable equilibria be observed; and (iii) which of the two classical concepts of stability best describes the conditions under which instability is observed? Under the conditions of a fad-like demand side externality in a market organized by the multiple unit double auction (MUDA), market equilibration occurs at a point where demand equals supply. The disequilibrium behavior follows the dynamics of the Marshallian model of dynamics, as opposed to the Walrasian model. These results confirm and extend the major findings of Plott and George who studied a similar environment with a downward-sloping supply. 相似文献

This exercise sets up interlinked labor and goods markets in a classroom macroeconomy. Students with worker roles are endowed with labor that can be consumed or sold to firms that post wages, purchase labor, and produce goods that can be either consumed or sold to workers. The money from sales is used by firms to purchase labor in the next period. Complicated record keeping is avoided by using ordinary playing cards to represent money and goods. The exercise can stimulate a discussion of potential output, unemployment, and the role of money in determining wages and prices. Use: This experiment can be used in introductory macroeconomics classes to teach concepts of the circular flow, real and money wages, unemployment, and labor market equilibrium and in intermediate classes to consider Keynesian and quantity theories. Time required: Fifteen minutes for reading instructions, 30 to 45 minutes for trading (depending on the number of periods), and 15 minutes for discussion. Materials: You will need one copy of the instructions for each person and one deck of ordinary playing cards for each replicated group of two workers and one firm. No money or other incentives are required. 相似文献

In this paper, we analyze the determinants of corporate saving in the form of changes in cash holdings for 11 Asian economies using firm‐level data from the Oriana Database for the 2002–2011 period. We find some evidence that cash flow has a positive impact on the change in cash holdings (i.e. that the cash flow sensitivity of cash is positive) and that the positive impact of cash flow on the change in cash holdings is larger and more significant in the case of smaller and presumably more constrained firms than in the case of larger and presumably less constrained firms in both developed and developing economies. Both of these findings corroborate the importance of financial constraints in Asian firms. In addition, we find that the cash flow sensitivity of cash declined after the global financial crisis and that Tobin's q has a positive impact on the change in cash holdings, especially in the case of larger and presumably unconstrained firms. 相似文献
