We assess the asymptotic consequences of estimating static models based on cross-section or panel data, when in reality the data are generated by a dynamic relationship, involving lagged dependent and current and lagged exogenous variables as well as individual effects. If the exogenous variable follows a stationary process, then the static estimators usually underestimate its long-run effect. This inconsistency is less severe, the higher the autocorrelation of the exogenous variable. If the exogenous variable follows a random walk with or without individual-specific drift, then the estimators are found to be consistent for the long-run effect. 相似文献

This article offers a perspective that serves as an alternative to dealing with workplace issues within the framework of managerial
capitalism. In accomplishing this, the article questions managerial capitalism by drawing from some of the same arguments
used to justify it—such as those based on corporate morality, the law, notions of bureaucracy, and social construction of
reality. Introducing and applying a strategy of inquiry known as deconstruction helps fulfill the underlying analysis. The
result is an articulation of a stakeholder perspective of employee responsibilities and rights.

The underidentification of linear models with measurement error does not necessarily extend to panel data models, as has been shown by GAiliches and Hausman (1986). We discuss and extend some of their results for a simple case and address particular issues concerning identification and asymptotic variances. 相似文献

It is widely known that in practice, different interviewers have different response rates, though there has been no systematic examination of whether this is because of differences among interviewers or differences among those areas allocated to the interviewers (area effects), or both. Furthermore, the conventional wisdom in survey research suggests that it is advisable to have the same interviewers return to the same respondents in order to maintain good response rates in longitudinal surveys, though once again there has been very little documented experimental research to support this. This paper makes use of the interpenetrated sample design experiment in Wave 2 of the British Household Panel Study (BHPS) (i) to explore the effects of interviewers' background characteristics and years of experience on response rates, (ii) to identify and estimate the differential effects of interviewers on response rates and compare the magnitudes of area and interviewer effects, and (iii) to investigate the impact of interviewer continuity. The analysis is facilitated by the use of cross-classified multilevel modelling. The paper also looks at the issue of interviewer continuity qualitatively, through the impressions of the interviewers themselves. 相似文献

经济发展水平、产业结构与碳排放强度——中国省级面板数据分析 总被引:8,自引:0,他引:8
利用我国29个省市自治区1995—2007年的面板数据,本文分析了二氧化碳排放强度同经济发展水平及产业结构之间的关系。通过多项计量检验,比较了不同计量模型之后,笔者选取了能够修正面板异相关和自相关的可行的广义最小二乘法(FGLS)模型。研究表明,(1)碳强度同人均GDP之间存在"N"形关系。(2)第二产业比重同碳强度存在正相关关系,即第二产业比重越高,二氧化碳排放强度就越高。(3)对经济发展与碳排放之间关系进行的情景分析表明,如果产业结构不改变,没有实施另外的政策,经济增长速度本身难以引致碳排放强度的大幅下降,2020年二氧化碳排放强度下降40%~45%的目标难以实现。 相似文献

Improving the status of malnourished children, and preventing children from becoming malnourished, lies at the heart of several of the Sustainable Development Goals. While many cross‐sectional studies examine correlates of stunting, they largely cannot identify drivers of change in stunting. We use two waves of panel data from Ethiopia and incrementally larger sets of fixed effects to control for time‐variant observable characteristics and time‐invariant unobservable characteristics. After controlling for these potential confounders, our analysis reveals that many factors that are associated with stunting in the cross‐section do not impact stunting dynamics. We also estimate individual fixed‐effects regressions, separately, according to baseline stunting status. We find evidence suggesting that while improved societal conditions drive many children out of a stunted state, certain exogenous factors may lead previously healthy children to become stunted. Overall, policymakers and practitioners would be wise to consult research utilising both cross‐sectional and panel data analyses in order to more effectively target already stunted children as well as vulnerable children who may be at risk of becoming stunted. 相似文献

The importance of foreign capital in the domestic economy cannot be underestimated as it bridges the gap between domestic capital demand and supply. Given this background the paper studies the relationship between the different types of foreign capital flows in the Southern Africa Development Region (SADC) region – foreign direct investment (FDI), remittances, cross border bank flows (CBF), overseas development assistance (ODA) – and domestic savings and investment, employing the panel cointegration test and the dynamic ordinary least squares method (DOLS). The empirical results reveal that there is a strong positive relationship between domestic investment and domestic savings, FDI and remittances. These findings indicate that FDI remittances help in overcoming the limits on the domestic capital formation in the SADC region through permitting a rate of investment which is in excess of that which can be generated by domestic savings. Important policy implications on attracting foreign capital flows are discussed in the paper. 相似文献

ABSTRACT In this paper, we aim to provide robust estimates of wage returns to education in Ethiopia. Previous estimates vary widely based on the scope and size of the study sample, variables employed, and estimation method. We use two recent rounds of national labour force survey data and a pseudo- (or synthetic) panel framework to address the well-known potential endogeneity of schooling in wage regressions. Birth-year cohort based pseudo-panel estimate of the return to an additional year of education is between 14 percent and 16 percent, 4 to 5 percentage points higher than that from ordinary least squares (OLS). The significant downward bias in OLS is further confirmed by two-year pseudo-panel estimates and remains robust, to a large extent, as we use an alternate model, change the estimation sample, and address selection bias concurrently with endogenous schooling using a novel approach. We discuss some possible explanations in the context of Ethiopia. 相似文献

Evidence on rural wage employment is thin and lacks nuance for different employment sources, insights on dynamic effects, and an understanding of the channels of effects. We assess conceptually and empirically the direct and indirect welfare effects of entry and continuation in different types of wage employment in rural Senegal. Using panel data, fixed effects and first-difference estimation, we show substantial positive welfare and linkage effects. We find that participation in wage employment increases per capita income by 143%, and reduces poverty, poverty gap and food insecurity by, respectively, 63%, 89% and 48%. While the direct effect on income is larger for non-agricultural and contractual wage employment, the indirect income effects through self-employment are more pronounced for agricultural and casual wage employment. Our results imply that job creation is important for rural development, that wage employment in agriculture can lead to considerable growth multiplier effects, and that synergies exist between large-scale and small-scale agriculture. 相似文献
