Cotton, both a source of livelihood for millions of poor rural households and a major source of export revenues, is a vital commodity for the economic and social development of Mali. Inefficiencies in the Malian cotton system at the ginnery and producers’ cooperative levels (e.g., late payment to farmers and poorly functioning credit schemes) have recently led to an important decline in supply, threatening the sustainability of the sector. Using regional data from 1998/1999 to 2008/2009, this study aims to quantitatively assess the contribution of key determinants, such as cotton prices and timely payment, toward the downward trend in cotton area. A dynamic supply model, based on adaptive expectations and partial adjustment, is employed to estimate the effects of prices and institutional factors, such as credit recovery rates and date of payment to farmers, on the Malian cotton supply. Results show that supply responds significantly to cotton prices relative to cereal and fertilizer prices. Date of payment varies across agricultural cycles and late payment negatively influences land devoted to cotton. Low credit repayment rates create disincentives to grow cotton. Therefore, the revitalization of the Malian cotton sector depends upon getting both prices and institutions right. 相似文献

This paper examines the effects of the institutional environment on West African cotton farmers’ technical efficiency (TE). First, key aspects of the cotton sector institutional environment are discussed, including input and credit access, and producers’ organisations. Then, a stochastic frontier production function, which incorporates technical inefficiency effects, is applied to farm level data collected in Benin, Burkina Faso and Mali. The survey includes farmers’ evaluations of the cotton sector institutional environment. Results suggest that institutional level features influence producers’ TE, besides farm‐level characteristics. Cotton growers who report a negative experience with the joint liability programme, who identify the cotton price mechanism or access to credit as the main constraints to performance, and who cultivate more hectares of cereals are technically more inefficient in producing cotton. Findings suggest that cotton farmers in Mali are less technically efficient in producing cotton than in Burkina Faso and Benin. Agricultural development policies focusing on reducing farmers’ financial stress, particularly through the establishment of adequate price mechanisms (i.e. higher farm‐gate prices and timely payments to farmers) and improvement in the input–credit markets should be encouraged to improve TE in West Africa. 相似文献

African agricultural production is modeled as a sequential decision process, with men's labor first allotted to clearing, then women's labor allotted to harvesting. A switching regression is then used to measure the constraints due to clearing labor capacity and harvesting labor capacity. The import of men's clearing labor depends on the valuation of shadow wages. Output appears to be more frequently constrained by husband's clearing labor, and in this situation male labor appears under‐utilized. However, output is also significantly constrained by female harvest labor, although the findings imply that female labor is over‐utilized at this stage. 相似文献

This study explores the controversy between the business and academic perspectives regarding earnings before interest, taxes, depreciation, and amortization (EBITDA). Some authors argue that EBITDA is not useful as an indicator, except for comparing companies within the same sector (Assaf Neto, 2003, McClure, 2006, Stumpp, 2000). On the other hand, the business world strongly uses this type of indicator as a tool to support its decisions (Schmalensee, 1985, Moraes, 2005). This difference in opinions has aroused interest in understanding the reasons for its use and has raised questions regarding the usefulness of EBITDA for comparing companies from both the same and different sectors. By applying Hierarchical Linear Modeling (HLM), the main goal of this research is to observe EBITDA behavior across companies selling goods in Brazil, comparing them within the same sector and across different sectors over time. This research allows for the analysis of the reasons why EBITDA patterns occasionally occur. The results show significant variation in EBITDA among companies across the same sector and across companies from different sectors. On the other hand, our results have shown, nevertheless, that the variability among companies from the same sector was the highest one, raising questions on the actual usefulness of this indicator to compare companies from the same sector. 相似文献

Mass tourism began in the Caribbean during the middle of the twentieth century. Unfortunately, increasing competition and a change in the motivation of tourists now force the authorities who manage these regions to introduce a new tourism offer that is not based directly on either the 3S (Sun, Sand, and Sea) or 3E (Entertainment, Excitement, Education) model. Hiking, trekking, and climbing, defined as mountaineering, might be one of these. This paper examines the potential for mountaineering in Cuba by verifying its accessibility for tourists. The assessment is based on a framework of true accessibility, which consists of two factors: (1) destination accessibility and (2) real access. Our results show that mountaineering in Cuba should be considered to be one of the key contributors to the development, prosperity, and well-being of all stakeholders, and especially for the communities outside the tourism enclaves. 相似文献

China’s international position as a net creditor nation provides it with foreign exchange that it has invested in Asian and African countries. One example is China's investment in the Russian Far East (RFE). Thousands of Chinese agricultural workers have migrated to the RFE in recent decades. They are often welcomed by Russian farmers who face a labor shortage and by local residents who can buy cheap vegetables from them, but there are others who resent their presence in the region as competitors. Our study is the first empirical study of this relationship. Our results demonstrate economic benefits to the Russian households. There are, however, some negative repercussions of Chinese farmers in the RFE, and the governments of both China and Russia need to manage the situation wisely. 相似文献

Smallholder farmers in developing countries encounter multiple barriers in access to inputs and technology, which prevent them from reaping the benefits from market participation. Women farmers face additional constraints due to gender norms that further limit their engagement in productive activities. While collective action has been shown to improve access to markets and economic outcomes for farmers overall, the evidence on the effects of cooperative membership for women smallholders remains limited. We investigate empirically the economic benefits of collective action for women farmers in the honey sector in Ethiopia. Relying on a rich data set on women honey producers, both cooperative members and non‐members, we evaluate the effects of belonging to a cooperative on three outcome variables through coarsened exact matching and regression analysis. Our results indicate that cooperative membership significantly increases the market price and the production quantity and, while the average effect on the share of product marketed is statistically insignificant, significant differences emerge for women with given characteristics. These results are shown to be robust to a number of tests that address biases from selection on observables and unobservables. An analysis of the heterogeneous effects of household membership in multiple groups finds that membership of self‐help groups or farmer associations amplifies the positive outcomes from belonging to a formal cooperative. Finally, qualitative findings derived from the same communities indicate self‐reported improvements in agency and self‐esteem among women members, thus reinforcing the importance of the quantitative findings. 相似文献
