在LSMS面板测量中的应用:从纵向研究中提高调查估计的质量
世界银行· 2025-01-14 07:53
Longitudinal Survey Challenges - Longitudinal surveys face challenges in maintaining accuracy over time due to sample attrition, migration, and sample fatigue, which introduce measurement errors[2] - Sample attrition, caused by deaths and relocations, along with the impact of new populations and migration flows, leads to underrepresentation in surveys[2] - Correct panel survey design and implementation require methods to address these issues at different stages: sampling design, data collection, and estimation[7] Proposed Methodology - The study proposes a weighted sharing method-based estimator that provides more accurate individual-level statistics compared to current estimators used in Uganda's national panel survey[2] - The proposed method shows higher stability when changing samples, particularly in cross-sectional estimates based on transition matrices[2] - The methodology focuses on improving survey quality by addressing sampling design, data collection, and estimation stages[8] Empirical Application - The methodology was experimentally evaluated using data from Uganda's national panel survey and the Living Standards Measurement Study (LSMS)[2] - The study applied the proposed methodology to LSMS-ISA data, using Uganda's national panel survey waves from 2009, 2013, and 2015 as a case study[10] - The empirical evaluation demonstrated the effectiveness of the proposed method in improving the quality of survey estimates[10] Data Collection and Tracking - Data collection improvements include flexible methods like phone interviews to reach non-responsive populations and minimal variable data collection for attritors[7] - Tracking rules are defined to balance the cost of tracking migrants with the potential bias introduced by their exclusion from the sample[29] - Proxy interviews and minimal variable sets are used to collect data from non-respondents and migrants, reducing sample attrition bias[53] LSMS-ISA Survey Overview - LSMS-ISA surveys are nationally representative longitudinal household surveys focusing on the relationship between living standards and agriculture[58] - The surveys track households and individuals over time, incorporating new members like immigrants and newborns to maintain representativeness[61] - Tracking methods vary across LSMS-ISA surveys, with some focusing on households and others on individuals, impacting representativeness and cost[63] Uganda National Panel Survey (UNPS) Case Study - The UNPS is a multi-purpose household panel survey in Uganda, providing data on income dynamics, consumption, and agriculture[71] - The study used UNPS data from 2009/10, 2013/14, and 2015/16 waves, with final datasets including 18,313, 17,377, and 15,905 individuals respectively[72] - The empirical evaluation of UNPS data showed that 45% of individuals from the 2009/10 wave were re-interviewed in 2013/14, with 30% of the sample being new individuals[73]

Regional Investment in Viet Nam
世界银行· 2025-01-09 23:03
Investment Rating - The report does not explicitly provide an investment rating for the industry or specific companies [1][2][3] Core Viewpoints - Vietnam aims to achieve upper middle-income status by 2030 and high-income status by 2045, requiring gross capital investments to account for 32-35% of GDP, with government investment at 7.3% of GDP annually to support infrastructure development [14] - Public investment in Vietnam has declined from 8% of GDP in 2011 to 6% in 2022, with chronic under-execution of investment budgets and significant delays and cost overruns in major projects [15][16] - Vietnam's infrastructure quality lags behind regional peers, with low expressway density and high road transport costs, which could impact its attractiveness as an FDI destination [19][20] - The public investment management (PIM) and intergovernmental fiscal (IGF) systems in Vietnam suffer from allocative inefficiencies, lack of coordination, and weak enforcement mechanisms, leading to suboptimal investment outcomes [28][29][30] Public Investment Trends - Vietnam's public investment has been declining, with the share of public investment in GDP falling from 8% in 2011 to 6% in 2022, while the economy remains capital-scarce compared to upper middle-income and high-income countries [24][25] - The central government's share in total government investment has decreased from 40% seven years ago to 20% in 2022, with provinces accounting for 80% of infrastructure investment [16][52] - Vietnam's infrastructure quality ranks 77th globally, behind regional peers like China, India, and Malaysia, with road transport costs being the highest in the region [19][20] Inefficiencies in PIM and IGF Systems - Allocative inefficiencies are evident in strategic infrastructure, with provinces over-investing in low-value projects like industrial parks and provincial ports, while national infrastructure spending has been squeezed [16][30] - There is a lack of investment in environmental protection and climate adaptation, with Vietnam being among the top 10 countries most affected by climate change, yet public investment in disaster protection is only 0.05% of GDP [40][41] - Implementation inefficiencies are significant, with an average delay of 5 years and cost overruns double the original budget for large-scale transport projects [42][45] Systemic Problems in Subnational PIM and IGF Systems - The lack of a conducive intergovernmental fiscal framework has led to fragmented investment decisions, with provinces holding 78-85% of public investment resources, leaving the central government with limited capacity to fund national infrastructure [52][53] - There is no enabling legal framework for vertical and horizontal investment coordination, with the State Budget Law banning the transfer of investment funds between provinces, creating financing gaps for regional projects [59][60] - The absence of effective incentive and enforcement mechanisms has resulted in a race-to-the-bottom competition among provinces, leading to wasteful investments in uneconomic projects [62][63] Recommendations and Next Steps - The report recommends rebalancing infrastructure investment from provincial to central levels, addressing legal loopholes, and establishing robust monitoring mechanisms to improve public investment efficiency [16][75] - It suggests adopting effective instruments for vertical and horizontal coordination, such as co-financing arrangements and matching grants, to enhance regional investment coordination [80][81] - The report also calls for a review of expenditure responsibilities and the establishment of a regional Public Investment Program to align with integrated masterplans and improve investment outcomes [78][79]
