With continually increasing demand for food accompanied by the constraints of climate change and the availability and quality of soil and water, the world’s farmers are challenged to produce more food per hectare with less water, and with fewer agrochemical inputs if possible. The ideas and methods of the system of rice intensification which is improving irrigated rice production are now being extended/adapted to many other crops: wheat, maize, finger millet, sugarcane, tef, mustard, legumes, vegetables, and even spices. Promoting better root growth and enhancing the soil’s fertility with organic materials are being found effective means for raising the yields of many crop plants with less water, less fertilizer, reduced seeds, fewer agrochemicals, and greater climate resilience. In this article, we review what is becoming known about various farmer-centred innovations for agroecological crop management that can contribute to agricultural sustainability. These changes represent the emerging system of crop intensification, which is being increasingly applied in Asian, African, and Latin American countries. More research will be needed to verify the efficacy and impact of these innovations and to clarify their conditions and limits. But as no negative effects for human or environmental health have been identified, making these agronomic options more widely known should prompt more investigation and, to the extent justified by results, utilization of these methodologies.  相似文献

A group of distinguished finance academics and practitioners discuss a number of topical issues in corporate financial management: Is there such a thing as an optimal, or value‐maximizing, capital structure for a given company? What proportion of a firm's current earnings should be distributed to the firm's shareholders? And under what circumstances should such distributions take the form of stock repurchases rather than dividends? The consensus that emerges is that a company's financing and payout policies should be designed to support its business strategy. For growth companies, the emphasis is on preserving financial flexibility to carry out the business plan, which means heavy reliance on equity financing and limited payouts. But for companies in mature industries with few major investment opportunities, more aggressive use of debt and higher payouts can add value both by reducing taxes and controlling the corporate free cash flow problem. In such cases, both leveraged financing and cash distributions through dividends and stock buybacks signal management's commitment to its shareholders that the firm's excess cash will not be wasted on projects that produce low‐return growth that comes at the expense of profitability. As for the choice between dividends and stock repurchases, dividends provide a stronger commitment to pay out excess cash than open market repurchase programs. Stock buybacks, at least of the open market variety, preserve more flexibility for companies that want to be able to capitalize on unpredictable investment opportunities. But, as with the debt‐equity decision, there is an optimal level of financial flexibility: too little can mean lost investment opportunities, but too much can lead to overinvestment.  相似文献

This study attempts to identify differences in the perceptions of top management (defined as CEOs, directors, and presidents) and employees (defined as middle and supervisory management) regarding (a) the effects of dependent care responsibilities on job performance, and (b) the extent of a firm's responsibility in providing support for those faced with caring needs concerning eldercare, childcare, substance abuse, and mental/physical handicaps. The results indicate that these two groups have significantly different perceptions of the effect of dependent care responsibilities on job performance, and on the firm's responsibility in providing support for three types of dependent care.  相似文献

Previous research has found that consumers ascribe mental states to for‐profit companies that enable them to elicit anger more easily than sympathy. The current study applies these findings to demonstrate how this evaluative asymmetry in consumer perceptions favor different strategies for individuals and companies managing conflicts and crises. First, it is shown that the mental states consumers ascribe to for‐profit companies enable them to elicit anger and admiration more easily than sympathy. Second, due to their ability to elicit anger more easily than sympathy, it is found that in conflicts between for‐profit companies and individuals, companies are evaluated more favorably when they focus attention on which side perpetrated the most harm, while individuals are evaluated more favorably when they focus on which side was most victimized. Third, due to their ability to elicit admiration more easily than sympathy, it is found that for‐profit companies derive greater benefits than individuals do from proactively taking responsibility to resolve crises rather than deflecting responsibility through claims of victimhood. Discussion focuses on marketing applications for companies managing conflicts and crises.  相似文献

This study utilized high frequency transactions data to analyze the trade size preference of informed traders in Indian equity markets. It is observed that informed traders at an aggregate level adopt stealth trading strategy, wherein they prefer medium sized trades over large sized trades in order to camouflage their private information. However, the stealth trading behavior varies across stocks, wherein informed traders prefer more large sized trades on firms that are part of an index compared to non-index firms. Trading behavior also varies across other market conditions. It has been noted that informed traders prefer large sized trades during periods of high market thickness, negative returns, and low volatility. This study also provides a rationale for such varied behavior of informed traders.  相似文献

We investigate the potential costs and benefits of firms constituting a heterogeneous pool of directors relative to more homogeneous boards. We measure director heterogeneity along six separate dimensions and divide board heterogeneity into occupational and social components. Our empirical analysis indicates that corporate complexity and managerial control exhibit significant influence on board heterogeneity. Using the heterogeneity of the county population of the firm's headquarters as an instrument, we also find that investors place valuation premiums on heterogeneous boards in complex firms but discount heterogeneity in less complex firms. Overall, our analysis indicates greater heterogeneity may not necessarily improve board efficacy.  相似文献

The paper investigates the influence of concentrated shareholding, boardroom politics and interest group politics in the quality of corporate governance in listed firms. It finds that the controlling shareholders exert influence in boardroom politics through family-aligned board and executive management. The evidence shows that concentrated ownership, family-aligned board and management, and political connection(s) of the controlling shareholder(s) tend to be inversely associated with the quality of corporate governance in a firm. The findings of the study suggest that the broad-based interest group politics which influence both political preference and corporate control politics contribute significantly to the current state of corporate governance in developing economies.  相似文献

This article maps some of the ways that the critique of tourism development in the Indian state of Goa is connected to Goan patriotism. Reactions against tourism in Goa assume a prior definition of 'Goa', and this definition is often patriotic. One of the central processes to understanding contemporary Goa's identity politics in the face of tourism is its former colonisation by the Portuguese. Treating the tourism critique in Goa as a geographically and historically specific discourse in this article means discussing four aspects of what will be called its spatiality: geopolitics, geohistories/disembeddings, socio-spatial biases and situatedness. It will be argued that the spatiality of the tourism critique shows that its connection to patriotism is not straightforward and immediate, but contingent. It will also be argued that although the spatiality of the tourism critique points to its heterogeneity, it is precisely because there are multiple constructions of 'Goa' and 'Goan identity' that the discourse constitutes its object, Goa.  相似文献

Multiple categories of retail products suffer limited shelf life, demand uncertainty, and, in some cases, long lead times. To provide retailers with an incentive to increase the stocking quantity of such products, manufacturers may offer an option to return unsold items at wholesale or less than wholesale prices. This article extends the additive price-dependent demand model in three ways. First, partial returns are optimal for the manufacturer but do not induce higher stocking quantities compared with when the manufacturer offers no returns. Second, in terms of the effect of investment in demand-enhancing activities, when retailers invest, they set higher resale prices, but an optimal partial returns policy still does not induce higher stocking quantity, whereas when manufacturers invest, the optimal returns policy induces higher stocking quantity. Third, when the manufacturer and retailer have different expectations of demand uncertainty, the retailer's estimate influences the expected profits for both, whereas the manufacturer's estimate has a major impact on its profits only.  相似文献
