Crop management innovations are often not discrete fixed stand‐alone options—and their adoption may imply various combinations and adaptations. This potentially confounds their impact assessment. This article assesses the resource saving and productivity enhancing impacts of a crop management package revolving around minimum tillage in maize‐based farming systems in northwest Ethiopia. An endogenous switching regression model was applied to plot‐ and household‐level survey data collected from 290 rural households operating 590 maize plots during the 2012 production year. Controlling for variations in plot and household characteristics, the average effect of minimum tillage package (minimum tillage package) on maize productivity is 0.44 t/ha. Compared to conventional practice (CP), adoption of the MTP decreased the average male and female labor use in maize production by 14.4 and 8.2 person‐days per ha, respectively. Similarly, MTP adoption decreased draft power use for land preparation by 13.2 pair of oxen‐days per ha. Compared to CP, in general, there is a considerable short‐run maize productivity gain and reduction in labor and draft power use under MTP.  相似文献

In a two‐country model where firms behave à la Cournot, we show that trade liberalization increases (decreases) the social desirability of those mergers that generate sufficiently large (small) reductions in marginal cost. There exists a range of intermediate levels of marginal cost savings such that marginal tariff reductions increase (decrease) the desirability of merger at sufficiently low (high) tariff levels. Moreover, in the neighborhood of free trade, we show that if trade liberalization increases the profitability of a merger, it necessarily also increases its desirability.  相似文献

In the aftermath of the 2008 financial crisis, the entire Indian banking industry was paralysed and their performance was shattered by the unfolding of enormous cases of Non-performing Assets (NPA). The study estimates the operating efficiency of 40 Indian banks for 5 years (2011–15) as a proxy of performance measure using the output-oriented DEA-BCC model. We find that nearly 62% of the state-owned banks and 47% of the private banks are inefficient indicating that the inefficient banks need to reduce their inputs or improve their output to become efficient. The study further investigates the relationship between intellectual capital (IC) and bank performance using a truncated regression model. The regression results show that out of the three components of intellectual capital, only human capital efficiency is positively and significantly associated with operational efficiency while structural capital and finance capital have a negative impact on the efficiency of banks. The study concludes that to achieve competitive edge banks should invest in their human capital. The results are robust in the case of financial variables taken as a proxy for performance.  相似文献

Abstract

Aims: To evaluate total costs and health consequences of a colorectal cancer (CRC) screening program with colonoscopy, fecal immunochemical tests (FIT), and expanded use of multitarget stool DNA (mt-sDNA) from the perspectives of Integrated Delivery Networks (IDNs) and payers in the United States.

Materials and methods: We developed a budget impact and cost-consequence model that simulates CRC screening for eligible 50- to 75-year-old adults. A status quo scenario and an increased mt-sDNA scenario were modeled. The status quo includes the current screening mix of colonoscopy (83%), FIT (11%), and mt-sDNA (6%) modalities. The increased mt-sDNA scenario increases mt-sDNA utilization to 28% over 10 years. Costs for both the IDN and the payer perspectives incorporated diagnostic and surveillance colonoscopies, adverse events (AEs), and CRC treatment. The IDN perspective included screening program costs, composed of direct nonmedical (e.g. patient navigation) and indirect (e.g. administration) costs. It was assumed that IDNs do not incur the costs for stool-based screening tests or bowel preparation for colonoscopies.

Results: In a population of one million covered lives, the 10-year incremental cost savings incurred by increasing mt-sDNA utilization was $16.2 M for the IDN and $3.3 M for the payer. The incremental savings per-person-per-month were $0.14 and $0.03 for the IDN and payer, respectively. For both perspectives, increased diagnostic colonoscopy costs were offset by reductions in screening colonoscopies, surveillance colonoscopies, and AEs. Extending screening eligibility to 45- to 75-year-olds slightly decreased the overall cost savings.

Limitations: The natural history of CRC was not simulated; however, many of the utilized parameters were extracted from highly vetted natural history models or published literature. Direct nonmedical and indirect costs for CRC screening programs are applied on a per-person-per modality basis, whereas in reality some of these costs may be fixed.

Conclusions: Increased mt-sDNA utilization leads to fewer colonoscopies, less AEs, and lower overall costs for both IDNs and payers, reducing overall screening program costs and increasing the number of cancers detected while maintaining screening adherence rates over 10 years.  相似文献

We construct a model of redistributive politics where the central government is opportunistic and uses its discretion to make transfers to state governments on the basis of political considerations. These considerations are the alignment between the incumbent parties at the central and state levels and whether a state is a swing state or not. A testable prediction from the model is that a state that is both swing and aligned with the central government is especially likely to receive higher transfers. We test this prediction using Indian data for 14 states from 1974–75 to 1996–97. We find that a state which is both aligned and swing in the last state election is estimated to receive 16% higher transfers than a state which is unaligned and non-swing.  相似文献

Does fairness matter in the hard bargaining and horse‐trading that is associated with trade negotiations? This paper presents a positivist analysis of the particular concepts of fairness that developing countries have appealed to in their trade negotiations within the auspices of the GATT and WTO, how these notions have evolved, and the impact that they have had on negotiated outcomes. Treating the concept of fairness as my central dependent variable, I argue that the notion of fairness can only be understood in terms of the institutional context it is embedded in, which includes institutional structure as well as the participatory processes that underlie it. I advance three hypotheses on the relationship between institutional context: the fairness discourse, and the influence and manoeuvre that member countries can have in shaping that discourse. Focusing on the role of fairness in the negotiation positions of developing countries, I explain its substance and evolution through learning and adaptation by these countries within the very particular institutions of the GATT and the WTO, and the coalitions they form a part of and interact within.  相似文献

What is the impact of product certification on small‐scale farmers’ livelihoods? To what extent does the participation of Ethiopian small‐scale coffee farmers in certified local cooperative structures improve their socioeconomic situation? To answer these questions, this article employs household data of 249 coffee farmers from six different cooperatives collected in the Jimma zone of Southwestern Ethiopia in 2009. Findings show that the certification of coffee cooperatives has in total a low impact on small‐scale coffee producers’ livelihoods mainly due to (1) low productivity, (2) insignificant price premium, and (3) poor access to credit and information from the cooperative. Differences in production and organizational capacities between the local cooperatives are mirrored in the extent of the certification benefits for the smallholders. “Good” cooperatives have reaped the benefits of certification, whereas “bad” ones did not fare well. In this regard the “cooperative effect” overlies the “certification effect.”  相似文献

Environmental productivity and Kuznets curve in India   总被引:2,自引:0,他引:2  
As a result of India's extremely rapid economic growth, the scale and seriousness of environmental problems are no longer in doubt. Whether pollution abatement technologies are utilized more efficiently is crucial in the analysis of environmental management because it influences the cost of alternative production and pollution abatement technologies. In this study, we use state-level industry data of sulfur dioxide, nitrogen dioxide, and suspended particular matter over the period 1991-2003. Employing recently developed productivity measurement technique, we show that overall environmental productivities decrease over time in India. Furthermore, we analyze the determinants of environmental productivities and find environmental Kuznets curve type relationship existences between environmental productivity and income. Panel analysis results show that the scale effect dominates over the technique effect. Therefore, a combined effect of income on environmental productivity is negative.  相似文献

In large measure, the voice that developing countries were able to exercise in Cancun was a result of their effective coalition formation. In this paper we present a brief overview of the various coalitions that played an important role at Cancun. The greater part of this paper focuses on one among these various coalitions: the G20 on agriculture. The G20 presents an especially fascinating case of a coalition that combined a great diversity of members and apparently incompatible interests. All theoretical reasoning and historical precedent predicted that the group would collapse in the endgame. And yet the group survived. We investigate the sources of the unity of this group and trace them to a process of learning that allowed the group to acquire certain structural features and develop strategies that helped to cement it further. While our central dependent variable is the cohesion of the G20, we also address the derivative question of the costs and benefits of maintaining such coalitions. The Cancun coalitions give us an excellent case of coalitions that managed to retain their cohesion, but also ended up with a situation of no agreement rather than a fulfilment of even some of their demands. We examine some of the causes behind the impasse in the negotiation process and suggest ways in which future outcomes could be improved.  相似文献

We analyze the effects of bilateral tariff reductions on the profitability of cost‐reducing horizontal mergers. Given Cournot competition in a two‐country world, for any positive tariff below a certain threshold, marginal trade liberalization is shown to encourage only those domestic mergers with sufficiently large cost‐savings and to discourage the rest. For tariffs close to, but smaller than, the prohibitive tariff, however, marginal trade liberalization necessarily encourages all domestic mergers. Moreover, we show that for a given level of cost‐savings, the impact of marginal trade liberalization may not reliably predict that of nonmarginal liberalization. Although at high tariffs, domestic mergers are shown to be unambiguously more profitable than cross‐border mergers, near free trade, mergers which yield the most cost‐savings become the most profitable. Thus, when comparing domestic and cross‐border mergers, trade liberalization encourages the type which yields the most cost‐savings.  相似文献
