Why Farmers Quit: A County-Level Analysis 总被引:1,自引:0,他引:1
Stephan J. Goetz & David L. Debertin 《American journal of agricultural economics》2001,83(4):1010-1023
We identify the effects of alternative explanatory variables on the propensity of U.S. farmers to cease farming, with a particular emphasis on understanding the roles of off-farm employment and federal farm program payments. Conventional ordinary least squares analysis using all counties suggests that off-farm employment has no statistical effect on the (net) number of farmers quitting between 1987 and 1997, ceteris paribus . A more refined analysis, which separates counties losing farmers from those that gained farmers, reveals subtle and less clear-cut effects of off-farm employment (and federal program payments) on farm exits. 相似文献

Interest in supporting local and regional food systems is rising and food hubs have attracted considerable attention among Federal, State, and local policymakers. This study explores the problem of endogenous hub location in fresh produce value chains in the Northeastern United States. To overcome limitations in the literature, we incorporate the effects of economies of scale and production seasonality into our models. Three experimental models are designed to examine the effects of alternatively applying yearly, quarterly, and monthly data on model solutions. We explicitly assess how interactions of scale economies and seasonality influence the structure and spatial attributes of an optimal regional produce aggregation hub system. The three models generate marketed different solutions and in many respects they lead to different conclusions about developing local/regional supply chains. The monthly model allows for production seasonality and actual hub operation cycle frequency and thus leads to more efficient hub solution with rich policy implications. 相似文献

A large number of developing countries have introduced trade policy reforms in recent years. These have been supported by
export promotion projects in the context of bilateral and multilateral development cooperation. The results of the advisory
approach so far adopted have been disappointing on the whole, so a reorientation is now taking place in the design of export
promotion. This article describes an alternative advisory approach by taking the Indo-German Export Promotion Project (IGEP)
as an illustration. 相似文献

The purpose of this study is to elucidate the stress–strain relationship by examining compound causes of frustration in the workplace. Drawing on configuration theory, this article describes stress patterns, that is, configurations of role stressors and social stressors, and underlying frustration and its negation, that is, mellowness. In addition, this article describes potential sources of such frustration‐stimulating stress patterns by examining constellations of employee and task characteristics. Based on a sample of 118 salespeople, the authors analyze the data using fuzzy‐set Qualitative Comparative Analysis—an analytic method pertinent to describing configurational patterns of causal factors. The findings from this study indicate the coexistence of alternative patterns of stressors for frustration. In addition, the findings show that configurational patterns for frustrated salespeople are quite different from those characterizing mellow salespeople. In summary, knowledge of these constellations of stressors helps sales managers detect conditions that frustrate, and develop strategies to diminish these conditions in order to improve sales force performance. 相似文献

So motivieren Sie Low Performer - Faule Kollegen – neudeutsch Low Performer – gibt es in der Arbeitswelt überall. Auch in der Pflege sind sie keine Seltenheit und wirken sich oftmals negativ auf das Betriebsklima aus. Abhilfe schafft ein individuelles Leistungsmanagement. 相似文献

Abstract. We analyze the relationship between per capita income and foreign aid. We employ annual data and five‐year averages and carefully examine the time‐series properties of the data. Panel estimations with dynamic feasible generalized least‐squares (DFGLS) show that aid generally has an insignificant or minute negative significant impact on per capita income (particularly in highly aid‐dependent countries). This holds true for countries with different levels of human development and income, as well as for different regions. We also find that aid has a small positive impact on investment, but a significant negative impact on domestic savings (crowding out) and the real exchange rate (appreciation).

The EU suffers from a democratic deficit that arises not first and foremost from a lack of institutional competencies, but rather from the double weakness of politics vis-à-vis economics and law at the European level. This “functional democratic deficit” renders the existing mechanisms of democratic control increasingly ineffective. Especially for its citizens, a politically integrated Europen Union might be difficult to grasp, and it may only be reached gradually through a continuous process of dynamic development; however, “United in Diversity” seems to be the better alternative, and not only for historical reasons. The direct elections for the European Parliament, although not denying deficits of democratic legitimacy and participation at the Union level, should not be underestimated in their legitimising influence for the Union as an associated structure of members without obvious hierarchies. 相似文献

This research is aimed at understanding firms' different types of ‘networking behaviors’, i.e., how and why firms affect their strategic network position by activities/routines/practices aimed not just at their business partners, but beyond such direct relationships. Thus, we adopt a network perspective to examine how firms exploit their webs of direct and indirect business relationships in order to assess and embrace the potential opportunities and constraints in the network. Based on the industrial network approach (INA), this exploratory research specifically focuses on networking behaviors in the UK manufacturing sector. Thirty-one semi-structured interviews with executive managers from fifteen firms were conducted. We identify four types of organizational networking behaviors by the way in which firms utilize their web of relationships to achieve certain goals. By using the concept of networking behaviors based on the INA as well as the strong-and-weak-tie argument in economic sociology, purposeful networking behaviors can be categorized into the following: information acquisition, opportunity enabling, strong-tie resource mobilization and weak-tie resource mobilization. These four ‘types’ of organizational networking behaviors provide a deeper understanding of how firms operating in business-to-business exchanges relate to and exploit their webs of direct and indirect relationships, taking into consideration the embeddedness and interconnectedness of the network context. 相似文献
