Shi Jie Yin Hang· 2025-03-07 23:10
Investment Rating - The report does not explicitly provide an investment rating for the industry Core Insights - The presence of Businesses of the State (BOS) in Brazil has significant implications for employment and business dynamism, particularly in sectors such as infrastructure and extractive industries [3][8] - BOS firms in Brazil pay a substantial wage premium, with an average wage premium of 18.5%, which decreases to 4.5% when controlling for worker characteristics [11][12] - Privatization events lead to a significant decline in workers' wages by approximately 10% in the first two years post-privatization, but do not show a robust decline in total employment [12][13] - BOS firms tend to employ more technical workers, indicating a higher level of innovation, and are larger and grow faster in terms of employment compared to private companies [3][9] - A higher concentration of BOS in a sector correlates negatively with young firms' participation and exit rates, while positively correlating with job creation rates and market concentration [14] Summary by Sections Introduction - The COVID-19 pandemic has reignited discussions on the role of state-owned enterprises (SOEs) and firms with state participation, emphasizing their importance in economic resilience and technology diffusion [7][8] Data and Methodology - The analysis utilizes a unique dataset from the Relação Anual de Informações Sociais (RAIS) covering over 3 million establishments and 40 million workers annually, focusing on firm-level data from 2010 to 2020 [17][18] Characteristics of BOS - BOS firms are generally older, larger, and pay higher wages compared to private firms, with average hourly wages of R$27.00 for BOS versus R$8.75 for private firms [38][63] - The average BOS employs 931 workers, while the average private firm employs only 12 [63] Employment and Wage Analysis - The report finds that BOS have a robust positive wage premium and that privatization negatively impacts wages but does not significantly affect total employment [11][12] - Employment in BOS is 19.5% higher than in private firms, with the difference increasing to nearly 30% in 2020 [57][58] Innovation and Business Dynamism - BOS firms exhibit higher innovation intensity, with 43.42% of BOS employing workers in technical occupations compared to only 3.04% in private firms [45][63] - The presence of BOS is associated with lower entrepreneurship and higher market concentration, suggesting potential adverse impacts on business dynamism [14]

Shi Jie Yin Hang· 2025-03-07 11:59
Core Insights - The report analyzes the fiscal and distributional impacts of VAT reform in Zimbabwe, emphasizing the importance of domestic revenue mobilization to create fiscal space and support macroeconomic stability [10][12][50] - The proposed VAT changes are expected to increase VAT revenue by 0.88% of GDP, but they may also lead to a 1.4 percentage point increase in poverty and a 0.14 percentage point rise in inequality [10][50] - The report suggests that any VAT reform must be accompanied by compensatory mechanisms targeting poorer households to mitigate adverse effects [10][14][50] VAT Structure and Proposed Changes - VAT has been a significant revenue source in Zimbabwe since 2009, surpassing income tax as the main contributor to government revenue [16][17] - The current VAT system includes a standard rate of 15%, with specific rates for certain goods, and the government plans to limit VAT exemptions and zero rates primarily to exports [18][22] - The 2024 budget proposes moving many previously exempt basic goods to the standard rate, which could enhance revenue but may adversely affect low-income households [22][25] Data and Methodology - The analysis utilizes data from the 2017 Poverty, Income, Consumption, and Expenditure Survey (PICES) and employs a fiscal impact analysis framework to assess the effects of VAT reform on household distribution [26][33] - The VAT gap is calculated using a supply and use table (SUT) to estimate the difference between potential VAT revenue and actual collections, highlighting both policy and compliance gaps [47][48] Results and Implications - The current VAT efficiency ratio in Zimbabwe has declined from 0.37 in 2012 to 0.29 in 2022, indicating significant policy and compliance gaps [47][48] - The report estimates that the policy gap accounts for 76% of the total VAT gap, suggesting that improving compliance could yield substantial revenue increases [48][49] - The proposed VAT reforms are projected to reduce the VAT gap from 5.62% of GDP in 2022 to an estimated 5.36% in 2024, with a corresponding decrease in the policy gap [50][51]
津巴布韦货币政策及汇率政策扭曲的财政成本
Shi Jie Yin Hang· 2025-03-07 08:04
Core Insights - The report identifies the fiscal costs of Zimbabwe's monetary and exchange rate policy distortions, highlighting three main channels through which these distortions affect tax revenue: the Oliveira-Tanzi effect, the impact of an overvalued official exchange rate on import duties, and the weakening of overall tax revenue due to informalization [9][11][34]. - It is estimated that from 2020 to 2023, high inflation and exchange rate distortions resulted in a loss of over $3 billion to the Zimbabwean treasury, indicating that stabilizing prices and eliminating exchange rate distortions could significantly enhance government revenue and help close the fiscal financing gap [9][11]. Group 1: Overview of Monetary and Exchange Rate Policy Distortions - Zimbabwe's macroeconomic instability is largely driven by high inflation, exchange rate distortions, and a challenging business environment, which have increased business costs and led to insufficient investment and a rise in informal activities [11][12]. - The Reserve Bank of Zimbabwe (RBZ) has engaged in quasi-fiscal operations (QFOs) that involve printing money to finance government and state-owned enterprises, contributing to rapid money supply growth and subsequent inflation [18][19]. - The report notes that the RBZ's actions have led to a significant increase in the money supply, with reserve money growth exceeding 1800% in 2023, and an inflation rate around 700% [11][12]. Group 2: Channels of Fiscal Cost - The first channel, the Oliveira-Tanzi effect, indicates that inflation-related payment delays reduce the real value of tax revenues, leading to significant losses in government income [34][38]. - The second channel involves the loss of customs revenue due to an overvalued official exchange rate, which results in lower import duty collections [34][45]. - The third channel highlights how exchange rate controls and high parallel market premiums push businesses into the informal sector, further eroding formal tax revenues [34][30]. Group 3: Methodology and Data - The report employs a multi-method approach to quantify the fiscal impact of monetary and exchange rate policy distortions on government revenue, focusing on the period from 2020 to 2023 [36][37]. - Data sources include monthly tax revenue figures, inflation rates, and informal sector size, with a particular emphasis on the relationship between inflation and the informal economy [36][47]. - The analysis utilizes a vector autoregression (VAR) model to predict the impact of inflation on the informal economy, allowing for a nuanced understanding of the relationship between these variables [46][47].
