TAX REFORM AND THE PROGRESSIVITY OF PERSONAL INCOME TAX IN SOUTH AFRICA

This paper investigates the progressivity of personal income tax in South Africa over the period 1989 to 2003. We use the effective, redistributive and disproportionality measures of progressivity and find that progressivity of the tax system increased over the period 1990 to 1994. However, during the first phase of the reform programmes the results are inconclusive with the Kakwani index (disproportionality measure) showing increased progressivity. The redistributive effect measure, on the other hand, indicates a marginal decline in progressivity. During the second phase of the reform programmes, both techniques suggest a worsening in progressivity. One explanation for the decline in progressivity during the latter period in the analysis is the fact that many more “new” taxpayers entered the tax net (higher income groups in our database) which made the distribution of pre‐tax income more unequal thus impacting on progressivity. On the other hand, the disproportionality measure shows a continuous, albeit volatile increase in progressivity over the latter period under investigation.     

Enforcement,Socioeconomic Diversity,and Tax Filing Compliance in the United States

In this article, we examine the determinants of tax filing compliance in the United States. We use county‐level data on non‐filing rates for the tax year 2000, obtained directly from the Internal Revenue Service. We include explanatory variables identified in the “rational compliance” framework, including an enforcement index against identified non‐filers, the audit rate of filers, and the average penalty rate for both filers and non‐filers. We also examine the role of socioeconomic diversity on tax compliance, testing whether within‐county heterogeneity in household income, language, race, and religion can help explain variation in non‐filing rates. We find that non‐filing is increasing with heterogeneity by race, although not by income or language, and that non‐filing is decreasing with heterogeneity by religious membership. As for enforcement variables, we find that non‐filing rates tend to fall with the enforcement index. Other variables have somewhat mixed results.     

The Complementarity between Tax Avoidance and Manager Diversion: Evidence from Tax Haven Firms

We investigate whether tax avoidance and manager diversion are complementary when the costs of diversion are low by comparing dividend payouts, performance, and overinvestments of tax haven firms versus other multinational firms based in countries with weak and strong investor protections. Desai and Dharmapala (2006, 2009a, b) and Desai et al. (2007) set forth a theory of tax avoidance within an agency framework (the D&D theory) based on the assumption that tax avoidance and manager diversion are complementary when the corporate governance system is “ineffective” (i.e., the manager's expected costs of diversion are low). Tax haven firms are corporate groups whose parent firms are incorporated in tax haven countries that are not the countries where the groups’ headquarters or primary operations are located (i.e., their “base” countries). We argue that tax haven incorporation potentially lowers the costs of diversion for managers of firms based in countries with weak investor protections. Using a sample from 28 base countries, we provide evidence that manager diversion and tax avoidance are complementary for tax haven firms based in countries with weak investor protections but not for tax haven firms based in countries with strong investor protections. Our results are consistent with the complementarity assumption underlying the D&D model and provide additional insights into the potential impact of the decentralization of the global firm.     

The Timing of Redistribution

We investigate whether late redistribution programs that can be targeted toward low income families, but that may distort savings decisions, can “dominate” early redistribution programs that cannot be targeted as a result of information constraints. We use simple two‐period overlapping generations models with heterogeneous agents under six policy regimes: a model calibrated to the U.S. economy (benchmark), two early redistribution (lump sum) regimes, two (targeted) late redistribution regimes, and finally a model without taxes and redistribution. Redistribution programs are financed by a labor tax on the young generation and a capital tax on the old generation. We argue that if the programs are small in size, late redistribution can dominate early redistribution in terms of welfare but not in terms of real output. Better targeting of low income households cannot completely offset savings distortions. In addition, we find that the optimal transfer and tax policy implies a capital tax of 100% and transfers exclusively to the young generation.     

Dual Income Taxation: A Promising Path to Tax Reform for Developing Countries

The dual income tax combines a progressive tax on labor income and a lower flat tax on income from capital. Unlike flat tax systems, a dual income tax provides developing countries greater flexibility in addressing tax competition while retaining progressivity. Countries could use the move to a dual income tax system not just as an opportunity to rationalize the taxation of income from business operations and investment but also as a vehicle for broader reform of their tax systems.     

Taxation and the Environment–Health–Poverty Trap: A Policy Experiment Perspective

Under pressures related to economic growth and environmental protection, China is facing an increasingly severe “environment–health–poverty” trap risk. Fuel taxation is generally considered an effective policy to counter such a risk. Since 2009 China has raised the fuel tax rate many times to enhance tax reform. However, the effects of this policy remain unknown. Therefore, it is vitally important to estimate the impacts of China's current fuel taxation policy on environment, public health and the national economy. As the first attempt in existing literature on China, this paper builds a general equilibrium framework with the feedback effect of public health on economy. We find that that the fuel tax policy benefits the adjustment of the economic structure and improves human health; however, it is detrimental to economic growth, public welfare and price stability. In this sense, it plays a limited role in reducing the trap risk and might not be sustainable in the long term.     

"SIN" TAXES AND POOR HOUSEHOLDS: UNANTICIPATED EFFECTS

This paper presents several hypotheses relating to the effects that tax hikes on tobacco and alcohol products may have on poor households. Its focus is limited to patriarchal households in which the head is “egoistic” and/or addicted (to alcohol and tobacco) and is also in control of the household budget. It is argued that “sin” tax hikes may adversely affect the welfare of household members other than the head, either directly through a re‐allocation of the household budget, or indirectly through higher health expenses caused by the substitution of cheaper and lower quality alcohol and tobacco products for higher quality products.     

The aging tax on potential growth in Asia

Population aging is becoming a prominent issue in Asia, especially for developing countries where demographic changes have asserted a downward pressure on the rate of growth. This paper refers to such potential unwanted effects as an “aging tax” and analytically examines them from a neoclassical perspective, using a Diamond-type overlapping generations model with endogenous retirement, survival rate, and old-age productivity. Based on this setup, negative impacts exist if too many old workers that are sufficiently unproductive choose to defer retirement under the aging pressure, which drains resources from future generations. Numerical simulations show that an aging tax can reduce the potential per capita growth rate (technology-adjusted) by up to 0.12 percentage points annually for some countries in Asia. Our results highlight that countries with sufficiently large labor shares (due to a high ratio of self-employment or a manual labor-centric production) and inadequate educational attainment are potentially the most sensitive and vulnerable to population aging.     

Budget deficits and money creation: Exploring their relation before Bretton Woods

The sovereign debt crisis in the Eurozone has rekindled the use of the North–South (core-periphery) terminology to refer to the heterogeneity of countries belonging to the Economic and Monetary Union (EMU). In the gold standard literature, this geographical partition had already been employed to oppose the fiscal profligacy and subsequent problems of convertibility of southern countries against the fiscal probity and long convertibility records of their northern counterparts. We provide statistical evidence that the group of countries that, with available data for 1870–1938, exhibited convertibility problems during the classical gold standard, for this reason called the pre-WWI “sometimes-floaters”, shared a pattern of fiscal dominance. This finding for the sometimes-floaters (southern European and South American countries plus Japan) differs from the non-fiscal dominance pattern that we obtain for the pre-WWI “never-floaters” (northern Europe and North America countries) when the Great War and its aftermath years are omitted. We also show that the presence of fiscal dominance was partly due to the lower levels of tax efficiency and political stability in the South.     

Tax Revenue Effects of Sectoral Growth and Public Expenditure in Uganda

This paper contributes to a growing strand of literature on the determinants of tax revenue performance in developing countries, particularly in Sub‐Saharan Africa. More specifically we estimate the tax elasticities of sectoral output growth and public expenditure. The unique features of this paper are twofold: First, we develop a simple analytical model for tax revenue performance taking into account some structural features pervasive in most developing countries with large informal sectors. Second, we test the model predictions on Ugandan time series data using ARDL bounds testing techniques. Results indicate that dominance of the agricultural and informal sectors pose the largest impediments to tax revenue performance. In addition development expenditures, trade openness, and industrial sector growth are positively associated with tax revenue performance. We propose policies to support the development of value added linkages between agricultural and industrial sectors while emphasizing the need to unlock the potentially large contributions of the informal sector with a view of widening the tax base.     

Policy Analysis and Development Evaluation of Digital Trade: An International Comparison

As an extension of traditional trade, digital trade is a new type of trade in the era of the digital economy. In this paper, we first analyze the digital trade‐related strategies of eight leading economies through word clouds and dissect China's digital trade‐related policies using the word frequency method by sorting through the digital trade‐related policy documents of 26 economies and Chinese provinces. We then evaluate the status quo of digital trade development in 111 countries and Chinese provinces by building a digital trade index system to determine the development environment and market potential. The results show that all countries attach great importance to digital technology, data and government guidance in the development of digital trade. The results also reveal that “development,” “service” and “construction” are the three most frequently used words in various Chinese documents. The overall level of China's digital trade is at the global vanguard, but is characterized by uneven regional development. In the era of digital trade, traditional international trade theory is also in urgent need of breakthroughs and innovation.     

Corporate In‐house Tax Departments*

In‐house human capital tax investment is a significant input to a firm's tax decisions. Yet, due to the lack of data on corporate in‐house tax departments, there is little empirical evidence on how tax departments are associated with tax planning and compliance outcomes. We expect the size of tax departments to be positively associated with the effectiveness of tax planning and compliance. Using hand‐collected data on the number of corporate tax employees in S&P 1500 firms over the 2009–2014 period, we find that firms with larger tax departments are associated with lower and less volatile cash effective tax rates. Furthermore, using tax employees' specialization, we identify tax departments' relative focus on planning or compliance and document a trade‐off between tax avoidance and tax risk. Specifically, tax departments with more of a tax planning focus have incrementally greater tax avoidance but higher tax risk, whereas tax departments with more of a tax compliance focus have incrementally lower tax risk but higher tax rates. Overall, this paper contributes to the literature by looking inside the “black box” of corporate tax departments and shedding light on the importance of human capital tax investment for tax outcomes.     

Trade Opening,Fiscal Reforms,Poverty, and Inequality: A CGE Analysis for Bangladesh

We assess the short‐ and long‐run impacts of tariff reform policies on Bangladeshi households' poverty and income distribution by developing an 86‐sector, four‐factor, and nine‐household‐group computable general equilibrium (CGE) model. The main findings are that the complete removal of tariffs leads to a decrease in overall poverty with rich household groups in a relatively better position. In the short run poverty incidence increases for rural landless, urban illiterate, and low‐educated household groups whereas rural large farmer and urban medium household groups enjoy improvements in all poverty indicators. In terms of income distribution, trade liberalization enhances inequality slightly, but there is a tendency towards more equitable distribution in the long run. The choice of a fiscal compensatory mechanism with consumption tax is likely to play a negative role in terms of poverty and inequality in the short run; however, interestingly, the results are pro‐poor in the long run.     

How does a Change in the Excise Tax on Beer Impact Beer Retail Prices in South Africa?

This article uses price data, collected by Statistics South Africa, to estimate the effect of a change in the excise tax on the retail price of beer. We find strong evidence that the excise tax on beer is overshifted to consumers. The pass‐through coefficient is estimated at 4.83 (95% CI: 4.02; 5.64) for lager, and at 4.77 (95% CI: 4.04; 5.50) for all beer (which includes dark beer). This implies that for every R1/unit increase in the excise tax, the retail price increases by about R4.80/unit. Of the 23 brand‐packaging combinations considered, the pass‐through coefficients vary between 2.39 and 10.05 (median = 5.30). The majority of the price change in response to a tax change occurs immediately, and prices have fully adjusted two months after the excise tax increase becomes effective. Pass‐through differs substantially across packaging types. The pass‐through coefficient on 750 ml bottles is substantially lower than that of 330 ml (or 340 ml) cans and 6 × 330 ml (or 6 × 340 ml) “six‐packs.” The overshifting of the excise tax has positive implications for public health policy, since they increase the effectiveness of alcohol taxes as a tool to reduce the (excessive) consumption of beer.     

What Blows in with the Wind?

The shift toward renewable forms of energy for electricity generation in the electricity generation industry has clear implications for the spatial distribution of generating plant. Traditional forms of generation are typically located close to the load or population centers, while wind‐ and solar‐powered generation must be located where the energy source is found. In the case of wind, this has meant significant new investment in wind plant in primarily rural areas that have been in secular economic decline. This article investigates the localized economic impacts of the rapid increase in wind power capacity at the county level in Texas. Unlike input‐output impact analysis that relies primarily on levels of inputs to estimate gross impacts, we use traditional econometric methods to estimate net localized impacts in terms of employment, personal income, property tax base, and key public school expenditure levels. While we find evidence that both direct and indirect employment impacts are modest, significant increases in per capita income accompany wind power development. County and school property tax rolls also realize important benefits from the local siting of utility scale wind power, although peculiarities in Texas school funding shift localized property tax benefits to the state.     

Trade and Tax Reforms in a Cash‐in‐Advance Economy

We examine the effects of both tariff‐only and coordinated trade‐tax reforms on market access, government revenue, and welfare for a small monetary economy, under the assumption that a certain fraction of purchases of each good must be financed with cash held in advance. We show that if the cash requirement ratio in the exportable sector is greater than that in the importable, then, contrary to previous results, (i) a uniform radial reduction of tariffs has ambiguous effects on both welfare and market access, (ii) tariff and consumption tax reforms that leave consumer prices unchanged may be more efficient in improving market access and welfare than a reform that involves only tariffs, and (iii) export and production tax reforms that keep producer prices unchanged may be welfare deteriorating.     

“营改增”倒逼消费税改革

在"营改增"不断推进的大背景下,为调整央地税制关系,稳定地方税源,消费税改革的呼声日益高涨。我国现行消费税虽历经了两次调整,但其现行税制仍不能适应升级了的消费结构,其征税范围需有增有减的调整,征税环节也需从生产环节下移,为弥补"营改增"为地方政府带来的空缺,可培养消费税为地方税主力。     

“Exports‐at‐Risk”: The Effect of Multimarket Contact in International Trade

Despite a well‐established literature examining possible impacts on competition in oligopolistic markets from multimarket contact (MMC) among diversified firms, only recently have trade theorists considered the possible effects of MMC among exporters in limiting the anticipated procompetitive role of imports. This article presents a first effort to test the empirical importance of a measure of this MMC, called “exports‐at‐risk,” on import prices (unit‐values). Suggestive evidence of anticompetitive impacts of MMC among exporters is obtained for highly traded four‐digit harmonized system (HS) products within the broad category of “fats and oils.” Exporters in fats and oils seem to price higher in markets where they meet rivals with the ability to retaliate against their “exports at risk.”     

Personal Income Tax Reform in China in 2018 and Its Impact on Income Distribution

In the context of personal income tax (PIT) reform in China in 2018, this paper examines some of the major issues of concern regarding the reform and income distribution. Using the China Personal Income Tax Micro‐simulation model, the paper compares the differences between the 2011 and 2018 PIT systems, and finds that residents relying on different income sources may face a large degree of real tax rate change. Once the tax system is altered to PIT 2018, the coverage of PIT for wage earners will decrease from 46.9 to 23.4 percent, the income redistributive effect will drop from 1.95 to 1.22 percent and the PIT's role in fiscal revenue will also be negatively affected. Nevertheless, if individual income continues to grow, the share of PIT in fiscal revenue is expected to return to the 2018 level in 2022, but its income redistribution function is difficult to recover in the short term. The paper finds that the effect of PIT on income distribution depends on the tax structure. Gradual transition to an “entirely comprehensive” tax system when conditions are appropriate will achieve better income redistribution results at a lower average tax rate.
