退耕农户长期生计分析 总被引:11,自引:0,他引:11
以陕西、青海两省4个县15个村400个退耕农户为研究对象,通过20年的成本效益分析,探讨了退耕还林对农户生计的长期影响,预测了退耕后林草产品的产出、价格和农产品产量,分析了样本农户退耕前后在土地利用、种植结构、收入和成本结构等方面的变化,对林草产品价格、退耕补助、毁林复耕等因素进行了敏感性分析。结果表明:在预测的价格和产出水平上,退耕提高了样本农户的收入水平。从长期看,退耕农户面临自然、技术和市场风险。要实现中国政府的生态建设目标,决策者应关注退耕农户尤其是退耕地比例高的农户的长期生计。 相似文献

Environmental Management and the Competitiveness of Nature-Based Tourism Destinations 总被引:13,自引:0,他引:13
Environmental management at nature-basedtourism destinations includes a private and apublic component. The former refers tovoluntary environmental protection activitiescarried out by individual (and groups of)tourism operators. These activities aremotivated by the dependence of the productprovided by the tourism industry on the qualityof the natural environment. Public sectormanagement, on the other hand, refers to theenvironmental regulations imposed on tourismbusinesses. The overall environmentalmanagement structure has a dual effect on thecompetitiveness of the tourism industry atnature-based tourism destinations. While theindustry may benefit from environmentalmanagement through demand stimulation, thetourism businesses also incur the associatedmanagement related costs. In this paper, theoverall effect of environmental management oncompetitiveness, as measured by aggregatetourism industry profitability, is estimated ina case study of Tropical North Queensland. 相似文献

Specialization,product development,evolution of the institution of the firm,and economic growth 总被引:3,自引:0,他引:3
This paper considers the effects of the division of labor on economic growth and welfare in a general equilibrium environment where changes in individual specialization and product development can proceed simultaneously. The nature of the dynamic equilibrium is shown to depend on the interaction of transaction efficiency, economies of specialization, and economies of complementarity. Where the dynamic equilibrium involves evolution in the division of labor, this will be associated with increased per capita real income and hence economic growth. It is also shown that the emergence of firms is an aspect of the evolution of division of labor if transaction efficiency for a producer good is lower than that for labor used to produce this good. 相似文献

Prior research has documented an association between disclosure quality and various economic benefits, most notably between the cost of equity capital and market liquidity. We extend this literature by investigating whether pharmaceutical firms that comply with recommended voluntary disclosures of the Financial Accounting Standards Board (FASB) exhibit lower bid-ask spreads, greater market depth, and lower cost of equity capital. Cross-sectional analysis using pharmaceutical firms reveals a negative association between disclosure quality and bid-ask spreads (both the total spread and its adverse-selection component), but no association between disclosure quality and either market depth or the ex ante cost of equity capital. Overall, our findings provide some evidence of benefits accruing to pharmaceutical firms that comply with the FASB's recommended voluntary disclosures under the assumption that lower bid-ask spreads reduce the cost of capital and strong evidence that complying with FASB's recommended disclosures provide a direct benefit to small investors, those who bear the entire weight of bid-ask spreads. 相似文献

The Center for Financial Stability (CFS) has initiated a new Divisia monetary aggregates database, maintained within the CFS program called Advances in Monetary and Financial Measurement (AMFM). The Director of the program is William A. Barnett, who is the originator of Divisia monetary aggregation and more broadly of the associated field of aggregation-theoretic monetary aggregation. The international section of the AMFM web site is a centralized source for Divisia monetary aggregates data and research for over 40 countries throughout the world. The components of the CFS Divisia monetary aggregates for the United States reflect closely those of the current and former simple-sum monetary aggregates provided by the Federal Reserve. The first five levels, M1, M2, M2M, MZM, and ALL, are composed of currency, deposit accounts, and money market accounts. The liquid asset extensions to M3, M4-, and M4 resemble in spirit the now discontinued M3 and L aggregates, including repurchase agreements, large denomination time deposits, commercial paper, and Treasury bills. When the Federal Reserve discontinued publishing M3 and L, the Fed stopped providing the consolidated, seasonally adjusted components. Also the Fed no longer provides the interest rates on the components. With so much of the needed component quantity and interest-rate data no longer available from the Federal Reserve, decisions about data sources needed in construction of the CFS aggregates have been far from easy and sometimes required regression interpolation. This paper documents the decisions of the CFS regarding United States data sources at the present time, with particular emphasis on Divisia M3 and M4. 相似文献

Recent microstructure research finds that liquidity risk, in particular its information component, plays an important role in explaining the post‐earnings‐announcement drift (PEAD). We decompose liquidity risk into an accounting‐associated component and a nonaccounting‐associated component and examine their relative importance in explaining PEAD. Our research is motivated by recent findings that liquidity risk is a systematic risk and earnings quality is negatively associated with liquidity risk. We find that the accounting‐associated component is more strongly related to PEAD returns than is its nonaccounting‐associated counterpart. Further analyses reveal that the relation between accounting‐associated liquidity risk and PEAD returns is weaker for firms with greater analyst following. We also find that in a significant market downturn, the relation between accounting‐associated liquidity risk and PEAD returns becomes more pronounced. Our study is the first to document a liquidity risk‐based role of accounting quality in explaining the PEAD phenomenon. It parses out the PEAD risk premia associated with accounting versus nonaccounting sources and, by so doing, sheds light on the role of accounting quality in shaping the liquidity risk‐PEAD returns relation. 相似文献

Public universities face critical challenges in terms of teaching, researching, and providing service. Funding mechanisms for various departments, programs, and professors have become increasingly intertwined with market-driven forces in light of neoliberal political and economic philosophies. In this essay, we illuminate neoliberalism and its multiple influences in university recreation, parks, and leisure studies departments. In noting classical theories of leisure and the deleterious aspects of neoliberalism, we encourage researchers, teachers, administrators, and students to resist these prevalent cultural trends, evoking a normative role for universities in the provision of a liberal education. 相似文献

The dynamics of workforce skill levels has a considerable impact on plant-level performance that is commonly overlooked by managers of manufacturing operations. In this study, we present a discrete event simulation model inspired by and validated in an actual manufacturing setting that includes short product life cycles, mid-volume production quantities, and a production environment consisting of assembly, inspection and testing.The effect of worker skill dynamics is analyzed using a factorial experimental design that contrasts the use of temporary versus permanent workers on manufacturing cost performance. The manufacturing costs assessed include labor, inspection and testing. The cost of reworking a defect is captured as an increase in the labor consumption. Materials costs are not assessed. At the core of the analysis, it is assumed that temporary workers have relatively less skill and therefore have higher average production times, higher average defect rates associated with their assembly activity, and lower rates of learning. In addition, the variance of the production time is higher for the temporary workers. Despite these indicators of performance problems, temporary workers may be used because of the considerably lower wage rate compared to permanent employees.Our in-depth case analyses shows that assigning skilled permanent workers to upstream build operations was superior to other policies deploying temporary workers, regardless of lot size or product complexity. Attesting to the importance of the labor mix component of manufacturing strategy, workforce deployment policies tended to dominate product switching frequency (a proxy variable for lot size and product mix) in impacting costs. 相似文献

Choice models in marketing and economics are generally derived without specifying the underlying cognitive process of decision making. This approach has been successfully used to predict choice behavior. However, it has not much to say about such aspects of decision making as deliberation, attention, conflict, and cognitive limitations and how these influence choices. In contrast, sequential sampling models developed in cognitive psychology explain observed choices based on assumptions about cognitive processes that return the observed choice as the terminal state. We illustrate three advantages of this perspective. First, making explicit assumptions about underlying cognitive processes results in measures of deliberation, attention, conflict, and cognitive limitation. Second, the mathematical representations of underlying cognitive processes imply well documented departures from Luce’s Choice Axiom such as the similarity, compromise, and attraction effects. Third, the process perspective predicts response time and thus allows for inference based on observed choices and response times. Finally, we briefly discuss the relationship between these cognitive models and rules for statistically optimal decisions in sequential designs. 相似文献
