Investment and saving in Angola and the Feldstein–Horioka puzzle

This article analyses the relationship between investment and savings for Angola using the Feldstein–Horioka puzzle, with monthly data from January 2000 to December 2013. Integer and fractional integration and cointegration techniques are employed to investigate the relationship between investment and savings. Several regression specifications are employed, concluding that the Feldstein–Horioka puzzle is not validated for the Angolan economy. Policy implications are derived.     

Gender,Decent Work,and Global Production Sharing in Indonesian Manufacturing

Abstract:

Global commodity chains reflect and affect gendered labor markets. This article uses the Decent Work framework from the International Labour Organization to analyze employment outcomes for Indonesian workers in manufacturing. This research investigates trends in feminized manufacturing sectors in variously sized firms. Regression analyses is used to evaluate how firm characteristics related to global production sharing effect decent work outcomes for women and men, as well as female share of employment itself. The results suggest that exports and FDI affect men and women differently and that feminization and decent work outcomes depend on how the sector is positioned along the global value chain.     

Truthful germs are contagious: A local-to-global characterization of truthfulness

We study the question of which social choice functions from an abstract type space to a set of outcomes are truthful, i.e., implementable by truthful mechanisms, when utilities are quasi-linear. For convex domains, our main theorem characterizes truthful social choice functions as those satisfying two properties: local weak monotonicity and vortex-freeness. The first of these constrains the function values at any two sufficiently proximal points, while the second asserts that its line integrals around sufficiently small triangular loops must vanish.The characterization implies a local-to-global principle that allows one to deduce truthfulness of a function from its behavior on arbitrarily small neighborhoods of each point. Other consequences include a simple alternate derivation of the Saks–Yu Theorem that weak monotonicity characterizes truthfulness of functions having a convex domain and finite range, and a sufficient condition for constructing truthful functions by “stitching together” truthful subfunctions on different subsets of the domain.     

新时期独立学院“80后”辅导员的角色定位与工作方法研究

近年来,在高校辅导员队伍中,特别是独立学院辅导员队伍中,＂80后＂已经成为主体。他们有着与上一代学生工作者完全不同的生存体验和独到的工作方式,他们在责任范围较宽和工作压力较大的情况下,面临着角色转换等问题。文章就＂80后＂辅导员在思想政治教育工作中如何进行角色定位,如何科学开展工作等问题进行探讨。     

Do jobs follow people or people follow jobs? A meta-analysis of Carlino–Mills studies

Do jobs follow people or people follow jobs? A meta-analysis of Carlino–Mills studies. Spatial Economic Analysis. This study examines the classic question as to whether ‘jobs follow people’ or ‘people follow jobs’ by performing a meta-analysis of 321 results from 64 Carlino–Mills studies. It is found that the results are highly divergent, but that more results point towards ‘jobs following people’ than towards ‘people following jobs’. When it comes to the reasons for the variation in results, we find that the results are mostly shaped by the geographical location, spatial resolution, and population and employment characteristics present in the data, as well as by the model’s specification, its functional form and the spatial weight matrix specification.     

Dynamic contracting under imperfect public information and asymmetric beliefs

We develop a dynamic principal–agent model to show how imperfect public information and asymmetric beliefs about payoff-relevant parameters, agency conflicts, and the agent's implicit incentives to influence the principal's posterior beliefs through his unobservable actions interact to affect optimal dynamic contracts. We make a methodological contribution to the literature by solving the continuous-time contracting problem using a discrete-time approximation approach. We obtain a simple characterization of optimal renegotiation-proof contracts in terms of the solution to a nonlinear ordinary differential equation (ODE). We then exploit the properties of the ODE to derive a number of novel implications for the dynamics of long-term contracts that alter the intuition gleaned from the previous literature. Optimism has a first-order impact on incentives, investment and output that could reconcile the “private equity” puzzle. Consistent with empirical evidence, the interaction between asymmetric beliefs, risk-sharing and adverse selection costs could cause the time-paths of the agent's incentive intensities to be increasing or decreasing. Our results also suggest that the incorporation of imperfect public information and asymmetric beliefs could potentially reconcile empirical evidence of an ambiguous relation between risk and incentives, and a non-monotonic relation between firm value and incentives. Permanent and transitory components of risk have differing effects on incentives, which suggest that empirical investigations of the link between risk and incentives should appropriately account for different components of risk.     

EMPIRICAL ESTIMATION OF NON-LINEAR INPUT–OUTPUT MODELS: AN ENTROPY ECONOMETRICS APPROACH

Despite theoretical advances, non-linear input–output models have been empirically applied only to a limited extent. This is mainly due to the fact that the number of parameters to be estimated is much higher than the number of available data points. Taking advantage of the recent proliferation of input–output databases and by applying an estimation strategy that relies on entropy econometrics, this paper suggests a way to estimate the parameters that characterize non-linear relationships between inputs and output. This non-linear modelling allows for considering time-specific input coefficients, instead of fixed ones. Several types of multipliers can be derived from this non-linear model, and the proposed generalized maximum entropy (GME) estimator allows estimating them from time series or cross-sectional datasets of input–output tables. The proposed GME technique is illustrated by means of an empirical application that estimates the parameters that characterize a non-linear input–output model for the Spanish economy over the period 1995–2011.     

Outsourcing and structural change. Application to a set of OECD countries

The examination in this paper aims to bridge outsourcing and structural change analyses in order to obtain more accurate insights into the extent of outsourcing and to extract more reliable policy recommendations for dealing with its effects. We do this by applying a ‘battery’ of outsourcing measurements to a group of OECD countries from 1980 to the mid 1990s. Expected results (e.g. the idiosyncratic outsourcing patterns of the UK) are confirmed on a more systematic and comparable basis, while original results (e.g. the low integration of business services in manufacturing in the former socialist economies) are based on the exploitation of new data.     

员工反生产行为组织控制的演化博弈分析

基于演化博弈理论和员工反生产行为组织控制的行为博弈演化过程,构建企业与员工共同参与的演化博弈模型.博弈的复制动态方程表明:员工选择显性反生产行为的比例、员工因选择反生产行为所获得的额外收益、企业对员工的反生产行为进行监管所投入的成本,企业观测到员工选择反生产行为时所作出的处罚都将对博弈均衡的结果产生影响.对此,应加强人力资源管理,加大组织支持力度,建立有效的控制机制.     

新疆劳动参与率偏低的原因分析

本文通过对新疆和全国劳动参与率的比较分析,得出新疆地区的劳动参与率明显低于全国水平,并对此产生的原因作了简要分析。除了各种宏观经济因素外,与新疆地区推行特殊的少数民族生育政策而带来的高幼儿扶养比和该地区传统的小富则安缺乏竞争意识的思想观念也有很大关系。
