Remittances from international labour migration: a summary of findings and issues for labour-exporting developing countries of the ESCAP region

International labor migration from the ESCAP region to the Middle East is analyzed, and patterns of remittances from migrants are examined. The focus is on "contract" migration, in which the workers involved have no intention of settling in the country of employment and which is characterized by a job contract that is concluded by the employer on behalf of the workers. Topics discussed include the labor market situation, controversies over the benefits of remittances, the flow of migration and the stock of workers in host countries, characteristics of migrating workers, management of the migration flow, the size and significance of remittance flows to ESCAP countries, and policy issues.     

Jackknifing Bond Option Prices

Prices of interest rate derivative securities depend cruciallyon the mean reversion parameters of the underlying diffusions.These parameters are subject to estimation bias when standardmethods are used. The estimation bias can be substantial evenin very large samples and much more serious than the discretizationbias, and it translates into a bias in pricing bond optionsand other derivative securities that is important in practicalwork. This article proposes a very general and computationallyinexpensive method of bias reduction that is based on Quenouille's(1956; Biometrika, 43, 353–360) jackknife. We show howthe method can be applied directly to the options price itselfas well as the coefficients in the models. We investigate itsperformance in a Monte Carlo study. Empirical applications toU.S. dollar swap rates highlight the differences between bondand option prices implied by the jackknife procedure and thoseimplied by the standard approach. These differences are largeand suggest that bias reduction in pricing options is importantin practical applications.     

Valuation of SGARAs IN THE Wine Industry: Time for Sober Reflection

The application of AASB 1037 Self Generating and Regenerating Assets provides little guidance to the commercial performance of winemakers. The valuation of grapevines essentially requires the valuation of a segment of a business (vineyards), from which is deducted the value of associated infrastructure. Grapevines are reported at a fictional "net market value" even though they cannot be bought or sold. The combination of recognising revaluation increments as distributable profits through the valuation of grapevines at "net market value", and the subsequent "amortisation" of those revaluation increments over the useful lives of the grapevines, creates a reporting maze which is more likely to confuse than inform.     

企业数字化转型能否提高创新绩效？来自上市公司的经验证据

随着信息技术的快速发展,企业数字化转型已成为推动创新与竞争力提升的关键。该研究基于2007-2022 年中国上市公司的大规模数据样本,采用最小二乘法线性回归和中介效应模型等统计方法,探讨了企业数字化与创新绩效之间的关系,以期揭示数字化背景下企业如何通过技术应用与管理创新提升创新能力,为企业数字化转型实践提供理论指导和决策参考。研究发现,数字化转型显著提升了企业的运营创新绩效和市场创新绩效,其中不仅直接影响显著,还通过管理赋能、投资赋能、营运赋能和劳动赋能等多重内在机制间接促进了创新绩效的提升。该研究发现不仅为理论研究提供了新的视角,同时也为实践中企业数字化战略的制定提供了有力的策略建议。     

热点之下的冷思考：数字化转型测度的困境与发展

当前,数字经济的浪潮席卷而来,深刻改变着每一个行业,没有哪个部门或组织能够免受数字化变革的影响。数字化转型已经成为大多数企业未来生存和发展的必然选择。在学术界,数字化转型的重大现实意义引发了众多学者的关注,已经逐渐成为管理学领域中备受瞩目的热点话题。数字化转型相关理论的发展必然需要定量实证研究的支持。然而,数字化转型这一概念自身的部分特性使得常用的测度方法大多在其研究中会表现出一些不足与缺陷,无法对数字化转型这一概念进行有效的测度。数字化转型测度方法的发展已经陷入了困境,这严重制约了数字化转型领域定量研究的发展。鉴于此,为了推动数字化转型相关研究的发展,本文将数字化转型的测度作为的核心主题,梳理研究中常用的数字化转型测度方法,探讨当前数字化转型测度面临的困境,分析困境产生的内在原因,进而针对如何突破数字化转型测度的困境提出相应的改进建议。     

企业创新链与资金链生态融合及水平测度研究——以生物医药企业为例

为促进创新链与资金链形成生态循环,推动企业高质量发展,从生态视角出发,运用系统分析方法,对企业创新链与资金链生态融合内涵进行界定,并分析其生态融合特征,构建两链生态融合系统模型,设计两链生态融合水平测度指标体系。基于规则的方法、熵权和物元可拓方法,设计指标数据评分规则与标准,构建两链生态融合水平测度模型,选47 家A 股上市生物制品企业为样本,测度两链生态融合水平。结果表明：生物医药企业创新链与资金链生态融合水平差异较大,存在薄弱环节,从两链融合系统环境、评价机制和平台建设提出建议,为反映两链生态融合程度和进行动态调整,以缓解企业创新融资约束和提高创新链资金配置效率提供理论方法和实际借鉴。     

中国出境旅游"双高"格局与政策取向辨析——兼与戴学锋、巫宁同志商榷

中国出境旅游的高增长和高消费现象引发了对出境旅游不经济性的讨论.本文通过与"中国出境旅游高速增长的负面影响探析"一文作者的商榷,认为出境旅游的迅速发展是我国现阶段宏观经济发展的必然结果,属于"补涨"性质;出境旅游消费存在"虚高"现象;出境旅游的发展为我国旅游业跨国经营创造了有利条件,而跨国经营是克服出境旅游不经济性的最佳途径.
