The author extends a previous work on migration in Italy "from 1958-1976 to 1958-1981, tests for the stability of the model and its coefficients, and uses the model for policy simulations and forecasting. The model performs as well over the extended sample period as over the original period and, even more important..., the model is found to be quite stable. This is remarkable in view of the economic turmoil that characterized the years by which the original sample period was extended." 相似文献

This paper presents an empirical analysis of the impact of climate change on agriculture in a typical developing country. The economic implications of climate change are estimated by using both a farm productivity and a Ricardian framework. Data are drawn from about 1,000 farms producing cereal crops in the Nile Basin of Ethiopia. The thin plate spline method of spatial interpolation was used to predict household specific rainfall and temperature values using meteorological station data collected for 30?years across the regions. We found that climate change adaptation has a significant impact on both farm productivity and farm net revenues. We complement the analysis by providing an estimation of the determinants of adaptation. Extension services (both formal and farmer to farmer), as well as access to credit and information on future climate changes are key drivers of adaptation. 相似文献

The role of family ownership in international entrepreneurship: exploring nonlinear effects 总被引:4,自引:0,他引:4

Empirical research on international entrepreneurship is growing, but results on the role of family ownership in this phenomenon
are inconsistent. We believe these inconsistencies owe to prior researchers having not yet investigated nonlinear relationships.
Drawing on opposing perspectives of stewardship and stagnation, we explore potential benefits and drawbacks of family ownership
for international entrepreneurship and explore nonlinear relationships among these two variables. Using a sample of 1,035
US family businesses and applying ordinal regression analysis, we find an inverted U-shaped relationship between family ownership and international entrepreneurship: International entrepreneurship is maximized
when family ownership stands at moderate levels. We discuss the implications of our findings for theory and practice and indicate
avenues for future research. 相似文献

Prior research on intelligent Internet agents has failed to address the needs of long‐lived data‐collecting agents, focusing instead on short‐lived transaction agents. Transaction agents typically run for a few seconds and retrieve information for a single transaction. With the staggering growth of electronic commerce, researchers and practitioners will want to design long‐lived data‐collecting agents that intelligently search for, retrieve, interpret, categorize, and store vast amounts of related information each time that they run. Such agents can run over the course of days rather than seconds and can be used by practitioners for decision support applications or by researchers as part of an empirical research methodology. This paper proposes a framework for agent sophistication, and emphasizes a number of design concepts for long‐lived Internet agents, including intelligence, validation, concurrency, recovery, monitoring, and interactivity. These concepts are used in the development of an illustrative tool called Electronic Data Retrieval LexicaL Agent (eDRILL), an object‐oriented data‐collecting agent. eDRILL is designed using the Unified Modeling Language (UML) and is written in Java. It gathers research data from an online auction. © 2000 John Wiley & Sons, Ltd. 相似文献

I introduce geographical specificity to world-systems concepts of core and periphery to develop a structuralist approach on semiperipheral development in the world-economy. I apply this approach to the historical trajectory of economic growth in Russia and east-central Europe since 1900. I find circumstantial support for Wallerstein's classic assertion that mercantilist semi-withdrawal is a potentially effective development strategy for semiperipheral countries and show that Russia raised its economic output above historical trend levels during the Soviet period. In contrast, east-central Europe fell short of historical trends during the Soviet period, suggesting that Russia's gains may have been made at the expense of its satellite empire. With the end of communism, both Russia and the countries of east-central Europe quickly returned to their long-term historical output levels relative to the core countries of western Europe. 相似文献

We use data from the Italian manufacturing industry to document a positive correlation between delegation and R&D. This result is robust to controlling for the determinants of R&D such as human capital, capital intensity and sectoral or regional effects. We further investigate the determinants of delegation and find that ownership concentration is significantly related to delegation. Among large firms with a dispersed ownership structure, larger ownership concentration implies less delegation, whereas the opposite emerges with more concentrated ownership. Differences between the Northern and Southern regions in terms of firms' propensity to delegate decisions and engage in R&D also emerge. 相似文献

Selection of a Representative Value Function for Robust Ordinal Regression in Group Decision Making 总被引:2,自引:1,他引:1
In this paper, we introduce the concept of a representative value function in a group decision context. We extend recently proposed methods UTAGMS-GROUP and UTADISGMS-GROUP with selection of a compromise and collective preference model which aggregates preferences of several decision makers (DMs) and represents all instances of preference models compatible with preference information elicited from DMs. The representative value function is built on results of robust ordinal regression, so its representativeness can be interpreted in terms of robustness concern. We propose a few procedures designed for multiple criteria ranking, choice, and sorting problems. The use of these procedures is conditioned by both satisfying different degrees of consistency of the preference information provided by all DMs, as well as by some properties of particular decision making situations. The representative value function is intended to help the DMs to understand the robust results, and to provide them with a compromise result in case of conflict between the DMs. 相似文献
