Consumption tax revenue and personal income tax: analytical elasticities under non-standard tax structures
(Taylor & Francis, 2016) Sanz Sanz, José Félix; Castañer Carrasco, Juan Manuel; Romero Jordán, Desiderio
This article models the elasticity of consumption taxation faced with changes in disposable income. Its calculation makes clear the importance of the design of the personal income tax and of the changes caused to the consumption of taxpayers. The modelling is performed for both individual taxpayers and the population as a whole.
The new public transport pricing in Madrid Metropolitan Area: A welfare analysis
(Elsevier, 2017) Burguillo, Mercedes; Romero Jordán, Desiderio; Sanz Sanz, José Félix
In a context of economic crisis, the amount of the demand public transport subsidies in Madrid has been reduced to control the level of public deficit. This has implied a worsening of public service quality and an increase of public transport prices. Using the Spanish Household Survey, this paper analyses the impact on welfare generated by the increase of public transport prices in 2008e2012. For this price and income elasticities have been computed using an LA/AIDS model. Price public transport elasticities are low (around 0.1%) and only significant for the years of the highest price increase. Fuel is substitutive for public transport with a cross-price elasticity of 0.25% and the other goods consumption is almost independent of the consumption of public transport with a cross-price elasticity of 0.06%. The results of income elasticies prove that public transport is a normal good. Results show that this new policy has harmed with a similar impact, low and medium income households. Those households have supported an average loss of welfare of 3.66% of their income. The welfare loss supported by the richest households is 1.5% of their income, which represents only a 40% of the average costs supported by the rest of households.
The Laffer curve in schedular multi-rate income taxes with non-genuine allowances: An application to Spain
(Elsevier, 2016) Sanz Sanz, José Félix
This paper models the connection between tax revenue and marginal tax rates in modern personal income taxes. In so doing, new analytical expressions for the elasticity of tax revenue to tax rates are derived taking into account global and schedular income taxes in the presence of non-standard allowances. Based on these new analytical elasticities the implicit Laffer curve is characterised and explored in detail. Calculations are performed for the individual taxpayer and the aggregate population. When applied to microdata, the model permits us to locate individually the position of every taxpayer on the entire range of the Laffer curve as well as to characterise the “representative” aggregate Laffer curve. The utility of the model to forecast revenue is illustrated by applying it to Spanish personal income tax. The model confirms that the Laffer curve is essentially an intrinsic individual matter although a virtual aggregate Laffer curve for the whole population can be inferred.
Corporate Taxation and Productivity Catch-Up: Evidence from European firms
(Wiley-Blackwell, 2018) Gemmell, Norman; Kneller, Richard; McGowan, Danny; Sanz, Ismael; Sanz Sanz, José Félix
In this paper, we explore whether higher corporate tax rates, because they lower the after-tax returns to productivity-enhancing investments, reduce the speed with which small firms converge to the productivity frontier. Using data for 11 European countries, we find evidence that their productivity catch-up is slower when the statutory corporate tax rates are higher. In contrast, we find that large firms are instead affected by effective marginal rates. Using the reduced-form model of productivity convergence of Griffith et al. (2009, Journal of Regional Science 49, 689–720), our results are robust to a host of robustness checks and a natural experiment that exploits the 2001 German tax reforms.
Reported gross income and marginal tax rates: estimation of the behavioural reactions of Spanish taxpayers
(Routledge, 2015) Sanz Sanz, José Félix; Arrazola-Vacas, María; Rueda-López, Nuria; Romero-Jordán, Desiderio
This article estimates, for the Spanish personal income tax, the elasticity of reported gross income to marginal tax rates. The identification of this elasticity has been performed using the reform approved by Law 35/2006, which came into force in January 2007. The elasticities obtained suggest the existence of important efficiency costs, with significant regional differences. The average elasticity estimated for Spain as a whole is 0.676. However, this elasticity is highly dispersed throughout the Spanish administrative regions, which indicates the unequal power of distortion of the tax. Thus, households whose principal source of income is salary display an elasticity of 0.337, compared to 0.682 for households whose main income source comes from business or savings. Lastly, a positive correlation is also detected between elasticity and income level: an elasticity of 3.6 is reached for taxpayers with an annual gross income exceeding 100 000€.
Los gastos fiscales. Un estudio
(Facultad de Ciencias Económicas y Empresariales. Decanato, 1991) Sanz Sanz, José Félix
El presente trabajo intenta hacer un recorrido conceptual a través de una de las figuras mas controvertidas de la Economía pública.Analizando su evolución para el caso español y llegando a la conclusión de que nos encontramos ante un elemento tributario de gran importancia, tanto en términos absolutos como relativos, no sólo cuantitativamente sino también por las múltiples implicaciones socio-económicas que subyacen ante su presencia,por 10 que, en buena lógica debería ser tratada por políticos y técnicos con el interés que las cifras le hacen merecedora. Una de las conclusiones básicas a las que se llega es la inexcusable necesidad de un Presupuesto de Gastos Fiscales para su control y seguimiento, como único instrumento válido para evitar la proliferación de tales figuras,fuente de distorsiones de muy distintos tipos entre las que se destacan las que afectan al nivel y composición de la inversión.
Revenue-maximizing tax rates in personal income taxation in the presence of consumption taxes: a note
(Taylor & Francis, 2016) Sanz Sanz, José Félix
This article computes revenue-maximizing tax rates in personal income taxes in the presence of consumption taxes. It finds that the traditional Laffer analysis, which neglects the effects of marginal tax rates on consumption, overestimates the magnitude of revenue-maximizing tax rates. The bias caused by this oversight is computed.
Is the corporation tax a barrier to productivity growth?
(Springer, 2020-01-31) Romero-Jordán, Desiderio; Sanz-Labrador, Ismael; Sanz Sanz, José Félix
Evidence shows that size matters in terms of productivity. Within this literature, this paper analyses whether corporation tax penalises the productivity growth of smaller enterprises (SEs) (< 20 workers). For this purpose, we use a sample of Spanish manufacturing companies for the period 1996 to 2009. Results show that corporation tax has a negative effect upon productivity growth in companies with the greatest profitability, whether large or small. However, in relative terms, this barrier is greater for SEs. The results therefore show that corporation tax prevents the SMEs in Spain from improving their low productivity.
A full-fledged analytical model for the Laffer curve in personal income taxation
(Elsevier, 2022-01-21) Sanz Sanz, José Félix
The standard approach to evaluate the Laffer curve of personal income taxation focuses on the impact on income tax revenue alone. However, this is an incomplete depiction of reality, as income tax rate changes also affect revenue collection from other taxes -i.e. consumption taxes and social security contributions. In addition, to the extent that administration and compliance costs correlate with tax rates, the Laffer curve should also consider this correlation. This paper develops a complete microeconomic model for the Laffer curve of personal income tax, taking into account all these omissions. Results confirm that these omissions generate the false illusion of a Laffer curve with a higher-than-real revenue maximum and a narrower prohibitive zone than exists in reality.
Fiscalidad y empleo en España
(Facultad de Ciencias Económicas y Empresariales. Decanato, 1994) Gonzalez Páramo, José Manuel; Sanz Sanz, José Félix
Este artículo pretende ofrecer los elementos básicos de tipo descriptivo, conceptual y empírico sobre los que sustanciar una discusión ordenada acerca del papel que juegan los impuestos en el mercado de trabajo. La Sección 2 comienza con una definición amplia de la fiscalidad sobre el factor trabajo, para pasar a describir las principales tendencias que ésta ha registrado entre 1980 y 1992 en los países desarrollados -OCDE y UE- y en España. La Sección 3 examina desde un punto de vista teórico las principales consecuencias económicas de los impuestos sobre el factor trabajo. Para ello, definiremos previamente la "cuña impositiva sobre el trabajo", concepto muy útil como medida sintética de las distorsiones que los impuestos introducen en el mercado de trabajo. En la Sección 4 se calculan las cuñas impositivas para España y para otros países desarrollados para los años 1979, 1983, 1987 Y 1992, con el fín de ilustrar la magnitud relativa de las distorsiones fiscales en las decisiones de oferta de trabajo y de empleo. La Sección 5 ofrece una breve síntesis de la evidencia empírica disponible para la economía española sobre la relación entre impuestos y empleo. La Sección 6 resume las principales conclusiones.
