This article reviews trends in poverty, economic policies, andgrowth in a sample of African countries during the 1990s, drawingon the better household data now available. Experiences havevaried. Some countries have seen sharp drops in income poverty,whereas others have witnessed marked increases. In some countriesoverall economic growth has been pro-poor and in others not.But the aggregate numbers hide systematic distributional effects.Taking both macro and micro perspectives of growth and povertyin Africa, the article draws four key conclusions. First, economicpolicy reforms (improving macroeconomic balances and liberalizingmarkets) appear conducive to reducing poverty. Second, marketconnectedness is crucial to enable participation in the gainsfrom economic growth. Some regions and households by virtueof their remoteness were left behind when growth picked up.Third, education and access to land emerge as key private endowmentsto help households benefit from new economic opportunities.Finally, rainfall variations and ill health have profound effectson poverty outcomes, underscoring the significance of socialrisk management in poverty reduction strategies in Africa.  相似文献

Several "best management practices" (BMPs) aimed at reducing movement of nutrients, pesticides, and sediment into surface water resources have been developed and promoted by Extension and other agencies over the past several years. This study utilizes actual farm-level economic and BMP adoption data to rigorously analyze the relationship between BMP use and farm profitability. Results indicate that adoption of nutrient BMPs has a significant positive effect on net farm income (NFI) for wheat and corn, while herbicide BMP adoption, particularly use of BMPs related to the application of atrazine on corn, has a small (but statistically significant) negative impact on income. Adoption of soil conservation BMPs is not shown to have a statistically significant impact on farm income.  相似文献

How to reduce poverty in lagging regions remains much debated and underserved with solid empirical evidence. This study illustrates an empirical methodology to analyze the pathways households followed out of poverty and to explore their potential in the future using 2000–2004 rural household panel data from two lagging provinces of China, Inner Mongolia and Gansu. It finds that rising labor productivity in agriculture has been key in understanding poverty reduction in rural lagging areas of these provinces and that it still holds much promise. Circular migration has also been important in Gansu, though less so in Inner Mongolia. On average, rural diversification has not proven to contribute much to poverty reduction and income transfers and agricultural tax abolishment have only helped at the margin. The findings from these two case studies highlight that the scope for reducing poverty in rural lagging regions can still be substantial in agriculture, also when nonagriculture drives national growth.  相似文献

We model the dynamic volatility and correlation structure of electricity futures of the European Energy Exchange index. We use a new multiplicative dynamic conditional correlation (mDCC) model to separate long‐run from short‐run components. We allow for smooth changes in the unconditional volatilities and correlations through a multiplicative component that we estimate nonparametrically. For the short‐run dynamics, we use a GJR‐GARCH model for the conditional variances and augmented DCC models for the conditional correlations. We also introduce exogenous variables to account for congestion and delivery date effects in short‐term conditional variances. We find different correlation dynamics for long‐ and short‐term contracts and the new model achieves higher forecasting performance compared to a standard DCC model.

International comparisons indicate that, on average, Belgian companies spend less on training than their French, German and Dutch counterparts. Encouraging companies to commit to training has consequently been an important policy goal over the last few years. One notable aspect of the policy to encourage training efforts by companies is that the effort is always represented in terms of the resources invested (input), not in terms of the learning achieved (output) or the quality of training programmes (throughput). Government policy is aimed at increasing the level of investment in company training. One of the questions we wish to investigate is whether this input-oriented approach to the training issue is actually effective. Whether companies will succeed in raising human capital to ever-increasing levels may depend not only (and maybe not even chiefly) on the extent of financial investment in training. The investment level does not necessarily determine the quality of the training processes developed by companies. Therefore, this paper focuses on the following research questions: (1) to what extent do companies monitor the systematic development of sufficiently effective training processes? In other words, is qualitative under-investment an issue, alongside financial under-investment? (2) Is the level of financial investment in company training correlated to the quality of training processes? The empirical data confirm that a kind of 'qualitative' under-investment can be reported and that the relationship between the level of investment in training and the quality of the training programmes is weak.  相似文献

Research in Motion's (RIM's) entry into the Chinese market during a time when many distractions —principally a patent dispute with NTP—occupied management's attention was not a foregone conclusion. China remained a difficult market to crack. One holdup was an impasse with regard to RIM's use of encryption technology and the Chinese authorities' desire to monitor e‐mail traffic and content. Here the technical and political concerns were entangled. To further complicate things, the entirety of RIM had until recently been preoccupied with the legal settlement with NTP in the United States. Issues in this study highlight real‐world dilemmas in a thriving firm. The founders are still in charge, and new markets present themselves regularly. A very real challenge is divided attentions. The standstill over market entry calls for integrative thinking—bringing together disparate and contradictory elements for resolution. RIM's way out will invariably involve embracing complex relationships in order to find a resolution to the various conflicting institutional forces. © 2008 Wiley Periodicals, Inc.  相似文献

From Industrial to Innovation Policy   总被引:2,自引:0,他引:2  
Industrial policy has been a cornerstone of economic policy in Europe after the world war and the transformation of basic industries like coal and steel were key issues at the beginning of European integration. In the 1970s and 1990s industrial policy shifted toward support of high-tech industries. In the seventies the importance of a more systemic view came up, policy had to address the specific weaknesses of the innovation system. The Lisbon agenda finally combines competitiveness with social and environmental goals. Industry plays an important role in generating welfare and industrial policy is in different forms and sorts back, high on the agenda.  相似文献

Attempts to explore empirically the link between HRM and firm performance are numerous. Yet, research on this link remains restricted to large companies. Little is known about the extent to which the existing results extend to small businesses. The purpose of the present study is to develop and test a conceptual framework linking HRM to financial performance that fits small businesses. The central question is whether the development of an intensive HRM is profitable for smaller organizations. For the development and optimization of the conceptual framework, we rely on human capital theory and bankruptcy prediction models. Using structural equation modeling, we study the mediating effect of voluntary turnover and productivity on the relationship between HRM intensity and one year lagged financial performance. The results show both productivity and profitability enhancing effects as well as a cost increasing impact of HRM intensity.  相似文献

This paper proposes to give a toll to help decision makers in critical situations. The principle of our research is based on a modelling approach for Cooperative Knowledge Based Systems. This approach is based on a Task/Method paradigm that we describe. We then propose to take into account collateral effects of tasks in order to support decision makers in a critical context. The proposed tool can then generate a degraded solution for which, collateral effects of previous tasks have been taken as new goals to reach. This study is possible thanks to the definition of several kinds of models: a Good Functioning Model and a Degraded Tasks Library.  相似文献

This article presents a taxonomy of financial restructuring strategies that have been used by national policy makers to manage financial crises in the past. The goals of financial restructuring are to preserve or, if necessary, restore the debtor‐creditor relationships on which the economy depends for efficient allocation of capital, and to do so at minimal cost. Costs include not only the direct costs to taxpayers of financial assistance, but also—and likely more important—the indirect costs to the economy that stem from misallocations of capital and incentive problems resulting from the restructuring. Countries typically apply a combination of tools, including decentralized, market‐based mechanisms as well as government‐managed programs. Market‐based strategies generally aim to strengthen the capital base of financial institutions and borrowers using some mix of debt forgiveness and capital infusions. Government‐led restructuring strategies include the establishment of entities to which non‐performing loans are transferred as well as government‐assisted sales of domestic financial institutions, often to foreign entrants. Market‐based mechanisms can provide low‐cost ways of resolving the coordination problems faced by countries in the wake of massive debtor and creditor insolvency, particularly when those mechanisms are effective in achieving the desirable objective of selectivity—that is, devoting taxpayer resources only to those borrowers and banks that, with temporary assistance, will be capable of sustaining themselves in the future. But limiting their range of application mainly to developed economies, such market‐based mechanisms also depend on an efficient judicial system, a credible supervisory framework and authority with sufficient enforcement capacity, and lack of corruption in implementation. Although government‐managed programs may not seem to depend as heavily on well‐functioning legal and regulatory institutions, such approaches—especially the transfer of assets to government‐owned asset management companies—also rely to some extent on such institutions. Asset management companies are less likely to achieve their goal of resolving the overhang of debt at reasonable cost when legal and political institutions are weak and ownership of domestic creditors and debtors is highly concentrated. Especially in such cases, complexity and failure to consider incentive problems when designing specific rules governing financial assistance can aggravate moral hazard problems, unnecessarily raising the costs of resolution. Resolution mechanisms tend to be most successful when—like across‐the‐board debt forgiveness programs implemented through redenominations of debt—they are simple in design and afford quick resolution of outstanding debts, offering little discretion to governments while providing incentives for the private sector to work down the remaining debt overhang.  相似文献
