ABSTRACTThe integration of West African rice market to the world market is assessed in order to derive the implication for food security. To this end, the transmission of rice price changes on the world market to selected markets in West Africa was examined to test for the presence of transaction costs. Using the two-regime threshold cointegration procedure on monthly price data, evidence in support of the hypothesis of asymmetric price transmission was found between Thailand and some West African markets. Price increases on the world market were more quickly transmitted to domestic price than were price decreases in Benin and Mali, suggesting short-run dynamic inefficiencies and the presence of transaction costs. In Senegal, the adjustment was linear, suggesting greater integration with the world rice market. The results suggest that West African governments should design and implement adequate policies to develop the domestic rice sector, improve market infrastructures in order to reduce their country dependency to international markets and ensure food security. 相似文献

Organizational culture is an important aspect to be considered by dynamic organizations in order to develop some competitive advantage to ensure enhanced organizational performance. This study aims to elaborate the dimensions of cultural construct in organizations of diversified sectors and their implications in Pakistan. Ten organizations were selected for the study. Four hundred and seventy eight questionnaires were received from these organizations. The questionnaires consisted of three parts, of these, the first part had nine elements that were related to organization and personal profile of the respondents, whereas the second part consisted of 60 elements of cultural construct, namely mission, adaptability, consistency, and involvement. In the third part, dependent variable appears as organization performance and was evaluated by asking eight questions. Results are revealed in two models: according to the first model, organization performance increases from negative 56% to positive 92% due to organizational culture with respect to education. And the second model is also significant at the 95% of confidence level (p < 0.05), and there is a positive relationship between independent and dependent variables. Organizational culture is an essential part of organizational success. Core organizational values typically emphasize special themes such as performance excellence, innovation, social responsibility, worker involvement, and quality of work life. Literacy rate in Pakistan is far below the literacy rate in developed countries. Educated employees play an important role in enhancing organizational performance, particularly in corporate setup. To measure affects of education on organizational performance through its construct involvement, consistency, adaptability, and mission have been endeavored in this study. 相似文献

Studies of improved seed adoption in developing countries are almost always based on household surveys and are premised on the assumption that farmers can accurately self-report their use of improved seed varieties. However, recent studies suggest that farmers’ reports of seed varieties planted, or even whether the seed is local or improved, are sometimes inconsistent with the DNA fingerprinting results of those crops. We use household survey data from Tanzania to test the alignment between farmer-reported and DNA-identified maize seed types planted. In the sample, 70% of maize seed observations are correctly reported as local or improved, while 16% are type I errors (falsely reported as improved) and 14% are type II errors (falsely reported as local). Type I errors are more likely to have been sourced from other farmers, rather than formal channels. An analysis of input use, including seed, fertiliser, and labour allocations, reveals that farmers tend to treat improved maize differently, depending on whether they correctly perceive it as improved. This suggests that errors in farmers’ seed type awareness may translate into suboptimal management practices. The average yield of seed that is correctly identified as improved is almost 700 kg per hectare greater than that of type I errors. This indicates that investments in farmers’ access to information, seed labelling, and seed system oversight are needed to complement investments in seed variety development. 相似文献

Terrorism is undesirable as it adversely affects the economic development of countries. This study explores the determinants of terrorism in 29 countries of sub‐Saharan Africa (SSA). The data is extracted from reliable sources spanning over 2005 to 2016. Econometric techniques relevant for panel data that control for unobserved heterogeneity (fixed effects) and endogeneity (generalized method of moment) are employed to estimate the specified models. The results indicated that low growth in per capita incomes along with political instability are the main driving forces responsible for terrorism. Similarly, military expenditures are influencing terrorism positively whereas corruption has impacted terrorism negatively in the SSA region. Further, the growth of both physical as well as human capital reduces terrorism. The paper suggests that the region should take appropriate steps for increasing income of the population, education and capital stock, along with ensuring political stability to eradicate terrorism from the region. 相似文献

For an incomplete-information model of public-good provision with interim participation constraints, we show that efficient outcomes can be approximated, with approximately full surplus extraction, when there are many agents and each agent is informationally small. The result holds even if agents' payoffs cannot be unambiguously inferred from their beliefs. The contrary result of Neeman [Z. Neeman, The relevance of private information in mechanism design, J. Econ. Theory 117 (2004) 55-77] rests on an implicit uniformity requirement that is incompatible with the notion that agents are informationally small because there are many other agents who have information about them. 相似文献

Analysis of producers' and intermediaries' livestock price expectations was used to describe the market in Quetta, the largest livestock market in the highlands of Balochistan Province, Pakistan, and to identify factors that determine price expectations of small ruminants. A total of 4800 expected prices for sheep and goats were collected from producers and market intermediaries at monthly intervals between January 1991 and December 1992. In addition to the expected price of the animal, liveweight, species, sex, breed, body condition (fatness), calendar day and month were recorded, and whether data were collected on a meat or meatless day. Monthly rainfall data were also collected. Models of goat and sheep price expectations were built to compare the similarity of the behaviour of producers and intermediaries. Results indicated that producers and intermediaries expected high prices from November to January and during religious holidays. They expected premiums and discounts related to animals' attributes. Liveweight and seasonality had the strongest effect on prices. Rainfall in the current and previous month was positively related to seller's expected prices suggesting that livestock are retained to take advantage of favourable grazing conditions. The models of price expectations showed that producers adjusted expected goat prices (P ≤ 0.10) for seasonality, liveweight, body condition, age, sex and breed, while they adjusted sheep prices for seasonality and liveweight only. High pay-offs could be expected if extension efforts focused on factors that determine sheep meat quality; however, the retail ceiling price of meat and the lack of grading are a disincentive to work in this direction. Seasonality of supply and demand is important in determining prices and this study provides baseline information for market scheduling; however, scheduling of sales of transhumant pastoralists may be difficult to achieve. Further investigation is justified to understand the gap in marketing knowledge between producers who sell in the villages and those who sell in Quetta. 相似文献

This paper investigates the direction of causation between GDP representing economic growth, exports and its different categories, imports and world income. After experiencing vigorous import-substitution in the past decades, Pakistan adopted an outward-looking strategy in the late 1980s with an emphasis on export promotion. A strong and stable relationship between GDP and exports and bi-directional causality between manufactured exports and GDP has been found. Export promotion policy is pursued consistently with an emphasis on manufactured exports and this is most likely to contribute adequately to economic growth in the long run. 相似文献
