The purpose of this paper is to comprehensively examine Ghana’s tax reform programme and investigate whether it has facilitated the revenue mobilization capacity of the overall tax system and of individual taxes on the basis of estimates of tax buoyancies and elasticities.

This study uses the proportional adjustment approach to estimate tax buoyancies and elasticities of the overall tax system and of individual taxes for the pre and post tax reform period over the 1970-2013 period.

The results show that in general, tax reforms had a positive influence on the overall tax structure and on the individual tax handles as evidenced in the more than unity buoyancy and elasticity. All the individual taxes, except excise duties, recorded buoyancies and elasticities of more than unity during the reform period.

Tax authorities ought to move away from income-based taxation which discriminates against saving and investment, in favour of consumption-based taxes in conformity with international standards. Emphasis must also be placed on those taxes that have high revenue elasticities. These taxes include the personal, corporate, the Value Added Tax, and the import duties.

In this study, the paper extends and disaggregates the data on taxes, account for discretionary tax changes from the historical time series data, and use the adjusted historical time series data to estimate tax elasticity. The study therefore provides an in-depth understanding of the effects of the tax reforms on the overall tax system and of individual taxes in Ghana.

Traditionally, the Laffer effect has been discussed in the context of endogenous growth models or in the case of the labor market with respect to willingness to supply more labor given a tax incentive on wages. The paper adopts an inductive approach to discuss it in the context of a product's market, say automobile industry in Turkey.

The author revisits the ad valorem tax model on a product and investigates how the elasticities of demand and supply and the tax rate are related to the Laffer effect. The author considers a special case where demand curve is non-linear and the supply curve is completely elastic. This specific model fits the practical case where the Turkish government expected the auto sellers to pass fully the temporary partial tax concession onto the consumers during the global crisis in 2009.

The author showed that the demand elasticitiy must be calculated neither at the intersection of the initial equilibrium nor that of the final equilibrium points, but somewhere else. The author defined a pass-through coefficient which was different from the classical burden of tax concept, calculating the degree of pass-through of a tax decrease from firms to consumers. Moreover, the author found a one-way relationship between the overall tax revenues of the government and a single sector.

The case of tax revenues where both the demand and supply curves are non-linear and non-extreme must be solved.

The author showed that the government's dual expectation of both boosting the economy, increasing employment and raising its tax revenues can sometimes be consistent given a usual upward sloping supply curve. In the case of a perfectly elastic supply curve, the tax revenues can even be higher with a higher level of equilibrium quantity.

The Turkish government aiming to support the production and employment in this leading export industry, may have expected this temporary tax decrease to be passed completely onto the consumers by the producers. However, this did not happen as producers’ prices to the consumers did not decrease as much as the amount of tax. This paper shows that the after tax elasticities and the current level of tax rate must have been compared.

The author pointed out to the importance of being clear in explicitly indicating at which points the elasticities derived from some function (tax revenue function) of equilibria variables (price and quantity) must be interpreted. In this paper, doing many numerical calculations allowed us to notice the proper point of calculation of the demand elasticity, which is the after-tax price along the “no tax demand curve”. Moreover, a pass-through coefficient is defined which is different from the classical burden of tax concept.

This paper examines the question of the extent to which redistribution can be achieved using a structure of consumption taxes with differential rates and exemptions. A local measure of progression, that of liability progression (equivalent to the revenue elasticity) is examined. Results are obtained for the Australian indirect tax structure. These are compared with structures in which only commodity groups with total expenditure elasticities greater than 1 are taxed. Comparisons are also made using equivalent variations, and inequality measures of a money metric welfare measure are reported.

This study analyses the impact of fiscal shocks on GDP, inflation and interest rates in Portugal over 1995–2017.

Multipliers are estimated using a structural VAR (SVAR) a' la Blanchard and Perotti (2002) using OECD elasticities. Changes in direct and indirect taxes are considered for fiscal shocks on the revenue side and changes in public consumption, investment and transfers for fiscal shocks on the expenditure side.

The analysis finds small tax multipliers and larger government consumption multipliers for growth, while short-term responses to shocks in transfer and investment spending are found to be negligible. Fiscal shocks have an ambiguous impact on inflation, and fiscal shocks of an expansionary nature are found to trigger declines in interest rates. The results are robust to different orderings of variables, to the selection of an alternative time period which excludes the financial crisis and to an alternative estimation technique.

A major limitation of the study relates to the relatively short time period which does not allow capturing the impact of possible structural breaks.

This analysis is relevant for countries, like Portugal, that display high debt levels and volatile market sentiment and lack an independent monetary policy.

Overall, the analysis of output multipliers compares well with some other studies conducted on the Portuguese economy and confirms the importance of the disposable income channel in the transmission of fiscal shocks to the rest of the economy. The study is one of the first to focus also on the implications of fiscal shocks on inflation and long-term interest rates. It is the first to apply the local projection method to estimate multipliers in Portugal.

Small businesses file taxes in accordance with the personal income tax code because they are considered flow-through entities. Thus, personal income tax reforms directly affect the incentives small business owners face regarding employment and operations. The paper aims to discuss these issues.

The authors use the changes in personal income tax rates during the 1993 and 2001-2003 reforms and micro-level data to estimate the effect of statutory tax rate changes on small business employment decisions.

The authors add two contributions to the current literature: first, the author allow for intertemporal tax planning and second, the author allow the firm’s decision to employ labor to be correlated with the firm’s wage bill decision. Estimation of a Heckman selection model for wage bills shows that the probability that a business will employ labor is 1.18 percent higher when current tax rates increase by one percentage point and 0.70 percent lower when future rates are expected to increase by one percentage point. Among firms that already employ labor, the median wage bill elasticity with respect to current tax rates is −0.64. These estimates are larger than those reported in previous research because my model includes future taxes and allows for correlation between the firm’s employment and wage bill decisions. Omitting the intertemporal tax responses biases the estimates of previous researchers upwards, whereas assuming the two firm decisions are independent biases estimates towards zero.

This paper assesses the impact of tax reforms on tax revenue mobilisation in Ghana.

The autoregressive distributed lag model together with dynamic ordinary least squares and fully modified least squares techniques were employed on a time-series data spanning from 1980–2018. Exploiting data from IMFs monitoring of fund arrangements database, an index of tax reforms is constructed as a function of the number of successfully implemented tax-related reforms and policy measures per year over the study period.

Having established the presence of co-integration between tax revenue and its determinants, this paper finds strong evidence that tax-related reforms exert positive and significant impact on tax revenue generation in Ghana. Among other covariates, the results show that the tax base (real GDP), public debt and education (human capital index) significantly boosts tax revenue in the long run.

The success of tax reforms in boosting revenue mobilisation has been examined in light of the buoyancy and elasticity of the tax system in Ghana, albeit with little emphasis on the extent to which tax reforms contribute to tax revenue mobilisation from econometric perspective. This paper fills this gap in the literature by analysing the impact of tax reforms on tax revenue mobilisation in Ghana. As a recommendation, well-designed and implemented tax reforms and policies aimed at increasing the tax base, education and effective utilisation of funds from public debt promise to be instrumental in boosting tax revenue in Ghana.

In recent policy discussions, the conventional wisdom is that adolescent smoking is substantially more tax- or price-responsive than adult smoking.¹ In a previous study, we used data from the first three waves of the National Education Longitudinal Study (NELS) to estimate the impact of taxes and prices on smoking initiation during adolescence (DeCicca, Kenkel, & Mathios, 2002). Contrary to the conventional wisdom, we found weak or non-existent tax/price effects in our models of the onset of adolescent smoking between 1988 and 1992. In this study, we use data from the 2000 wave of NELS, when most respondents were about 26 years old. Although cigarette prices increased by almost 40% in real terms between 1992 and 2000, smoking prevalence among the NELS respondents also increased from 18% to 23%, about the same increase observed in other cohorts over these ages.

Local governments are expanding their revenue portfolios and becoming less dependent on property taxes. It should not be assumed, however, that this diversification is increasing the stability of local governmentsʼ own source revenue, as previous research suggests. It is thus important for local government officials to know how this process will affect the stability of their own source revenue, as they are almost certainly diversifying away from a stable tax, the property tax (Groves and Kahn, 1952; McCubbins and Moule, 2010), and moving toward a more volatile tax, such as the sales tax. Using county-level data in thirty-five states, I examine the effect of local option sales taxes (LOSTs) on the volatility of own source revenue and find that greater use of LOSTs increases revenue volatility.

In the last decade there has been considerable interest in the analysis of Trade Union behaviour, but surprisingly little discussion of the effect of tax changes on wage demands. Previous analyses have been limited by the use of simple tax structures. The discussion is extended by considering a multi‐rate tax system that can easily be applied to most countries. The effect on unions′ wage demands of eliminating the top marginal tax rate, while raising VAT, is examined in detail. It is shown that this policy can be expected to lead to an increase in the wage demands of all unions, producing a once‐and‐for‐all increase in nominal wages and unemployment.
