Essays in dynamic optimal taxation: working experience, unemployment scarring and poverty

This thesis investigates the design of optimal tax systems in dynamic environments. The first essay characterizes the optimal tax system where wages depend on stochastic shocks and work experience. In addition to redistributive and efficiency motives, the taxation of inexperienced workers depends on a second-best requirement that encourages work experience, a social insurance motive and incentive effects. Calibrations using U.S. data yield higher expected optimal marginal income tax rates for experienced workers for most of the inexperienced workers. They confirm that the average marginal income tax rate increases (decreases) with age when shocks and work experience are substitutes (complements). Finally, more variability in experienced workers' earnings prospects leads to increasing tax rates since income taxation acts as a social insurance mechanism. In the second essay, the properties of an optimal tax system are investigated in a dynamic private information economy where labor market frictions create unemployment that destroys workers' human capital. A two-skill type model is considered where wages and employment are endogenous. I find that the optimal tax system distorts the first-period wages of all workers below their efficient levels which leads to more employment. The standard no-distortion-at-the-top result no longer holds due to the combination of private information and the destruction of human capital. I show this result analytically under the Maximin social welfare function and confirm it numerically for a general social welfare function. I also investigate the use of a training program and job creation subsidies. The final essay analyzes the optimal linear tax system when there is a population of individuals whose perceptions of savings are linked to their disposable income and their family background through family cultural transmission. Aside from the standard equity/efficiency trade-off, taxes account for the endogeneity of perceptions through two channels. First, taxing labor decreases income, which decreases the perception of savings through time. Second, taxation on savings corrects for the misperceptions of workers and thus savings and labor decisions. Numerical simulations confirm that behavioral issues push labor income taxes upward to finance saving subsidies. Government transfers to individuals are also decreased to finance those same subsidies.

Three Essays on Economic Development in the Natural Resources Sector

This thesis examines two ongoing development projects that received financial support from international development organizations, and an alternative mining tax proposed by the academia. Chapter 2 explores the impact of commoditization of coffee on its export price in Ethiopia. The first part of the chapter traces how the Ethiopian’s current coffee trade system and commoditization come to be. Using regression analysis, the second part tests and confirms the hypothesis that commoditization has led to a reduction in coffee export price. Chapter 3 conducts a cost-benefit analysis on a controversial, liquefied natural gas export project in Peru that sought to export one-third of the country’s proven natural gas reserves. While the country can receive royalty and corporate income tax in the short and medium term, these benefits are dwarfed by the future costs of paying for alternative energy after gas depletion. The conclusion is robust for a variety of future energy-price and energy-demand scenarios. Chapter 4 quantifies through simulation the economic distortions of two common mining taxes, the royalty and ad-valorem tax, vis-à-vis the resource rent tax. The latter is put forward as a better mining tax instrument on account of its non-distortionary nature. The rent tax, however, necessitates additional administrative burdens and induces tax-avoidance behavior, both leading to a net loss of tax revenue. By quantifying the distortions of royalty and the ad-valorem tax, one can establish the maximum loss that can be incurred by the rent tax. Simulation results indicate that the distortion of the ad-valorem tax is quite modest. If implemented, the rent tax is likely to result in a greater loss. While the subject matters may appear diverse, they are united by one theme. These initiatives were endorsed and supported by authorities and development agencies in the aim of furthering economic development and efficiency, but they are unlikely to fulfill the goal. Lessons for international development can be learnt from successful stories as well as from unsuccessful ones.

The Brain Drain : Myth and Reality - What it is and What Should be Done (Working Paper 13)

The brain drain debate has been marked by a considerable amount of confusion and frustration, largely because there has been relatively little hard data available, and that which exists has often been twisted into very different forms by those with competing policy agendas. The first goal of this paper is to pull together and summarize the available evidence regarding the size and nature of the outflows, thus establishing an empirical basis from which the issue can be addressed. The second goal is to address some of the major related policy issues. This begins with some general brain drain policy principles. The personal income tax cuts solution is then addressed with simulations of the effects on government revenues and the associated costs “per brain”, thus putting such discussions on a much firmer empirical footing. A number of alternative proposals are then suggested for various problem groups of brain drain workers.

Comportamiento del impuesto a la renta en la recaudación tributaria de la provincia del Azuay durante el último quinquenio

En la Constitución del Ecuador, en lo referente al Régimen Tributario, se busca la equidad, la importancia de la tributación directa, entre otros, garantizando de esta manera el Buen Vivir. Una vez revisadas las cifras, en la provincia del Azuay, los impuestos indirectos tienen un mayor nivel de recaudación. Este comportamiento atípico con lo que ocurre a nivel nacional, es lo que motivó la realización del presente trabajo, en donde bajo un enfoque sistémico se busca las posibles causas que lo originan. Para ello se recurrió a la información de recaudación tributaria que posee el Servicio de Rentas Internas. Partiendo de un análisis de la recaudación de impuestos a nivel nacional durante el quinquenio 2008-2012, se observa que el Impuesto a la Renta y el Impuesto al Valor Agregado son los de mayor recaudación dentro de los grupos de impuestos directos e indirectos respectivamente, contrastando con el comportamiento a nivel regional, y de la provincia del Azuay. El estudio realizado llevo a validar posibles causas que inciden en los niveles de recaudación del Impuesto a la Renta en la provincia, como: la composición y nivel de recaudación por clase de contribuyentes,el predominio de actividades económicas, la presencia de grandes contribuyentes con actividades específicas y los ingresos por remesas como generadoras de consumo.

Implicaciones tributarias en la determinación del impuesto a la renta como resultado de la revaluación de propiedad, planta y equipo en el sector industrial, en el cantón Cuenca a partir de la implementación de las NIIF en el Ecuador

En el Ecuador, a partir del año 2010, por resolución de la Superintendencia de Compañías, las compañías que se encuentran reguladas por este organismo, deben aplicar de manera obligatoria las Normas Internacionales de Información Financiera (NIIF), cuyo objetivo fundamental es que los Estados Financieros reflejen la realidad de la compañía y puedan ser comparables a nivel mundial, permitiendo una mayor competitividad y mejor toma de decisiones. La exención de la NIIF 1 permite optar en la fecha de transición a las NIIF por la medición de una partida de propiedad, planta y equipo por su Valor Razonable, y utilizar este valor como Costo Atribuido lo que implica contablemente un incremento en el valor tanto del activo como del patrimonio así como el reconocimiento de impuestos diferidos. Las NIIF no están diseñadas para realizar reportes impositivos por lo que la revaluación en los elementos de propiedad, planta y equipo generó implicaciones tributarias en la determinación del Impuesto a la Renta sobre todo en el sector industrial porque las compañías que pertenecen a este sector tienen en sus activos un valor significativo en propiedad, planta y equipo. El presente trabajo de investigación se lo realizó a través de un estudio de caso a una de las compañías objeto de estudio así como también a través de la aplicación de encuestas a las compañías que pertenecen al sector industrial del Cantón Cuenca y del análisis de la información que consta en la página de la Superintendencia de Compañías de dichas compañías.

Branqueamento de Capitais, Fraude Fiscal e Corrupção Internacional

Resumo: a fraude fiscal é um dos crimes que pode dar origem a um outro crime, o crime de branqueamento de capitais e/ou lavagem de dinheiro, como é mais conhecido por exemplo no Brasil. O branqueamento de capitais é apenas um dos exemplos do branqueamento de vantagens. Toda esta actividade pode ser incluída, em sentido amplo, na chamada corrupção internacional. Quanto mais internacionais forem estas actividades – fraude fiscal e branqueamento de capitais -, mais eficazes serão os seus proveitos. A fraude fiscal é um crime que pode atingir montantes mais elevados no caso de poder ser praticado em cenários internacionais. O branqueamento de capitais é também um crime que pode atingir montantes mais elevados no caso de poder ser praticado em cenários internacionais. Assim, a corrupção internacional em sentido amplo pode ser apelidada como mercado ideal para a criminalidade. Estamos também a falar de multinacionais do crime. § Abstract: tax fraud is a crime that can lead to another crime, the crime of money laundering. Money laundering is just one example of the whitening benefits. All this activity can be included in a broad sense, the international corruption. The more international are these activities - tax evasion and money laundering - the more effective will be the income. Tax fraud is a crime that can achieve higher amounts if it can be practiced in international scenarios. Money laundering is also a crime that can achieve higher amounts if it can be practiced in international scenarios. Thus, the international corruption in the broad sense can be dubbed as ideal market for the crime. We are talking also about transnational crime.

Tax and equality in 1972: The case of Lodge v FCT

This paper is part of a larger project described at http://www.law.uq.edu.au/australian-feminist-judgments-project as follows: This project draws its inspiration from two significant recent developments in law and feminist scholarship. The first has been the emergence in Canada and the UK of feminist judgment-writing projects, in which feminist academics, lawyers and activists have written alternative judgments in a series of legal cases, imagining the different decision that might have been made by a feminist judge hearing the case. The second has been the incremental shift in recent years in the number of women judges and Magistrates presiding in courts and tribunals throughout Australia. As part of this project, a group of scholars will write alternative feminist judgments. This paper is one of the alternative feminist judgements. The case used for this discussion is Lodge v Federal Commissioner of Tax [1972] HCA 49. In that case, a woman, earning income by way of commission in her occupation as a law costs clerk, which she carried out at her home, claimed to deduct from her assessable income child care fees that enabled her to devote time and attention to her work. The High Court held that no right to a deduction had arisen. It found that, although the purpose of the expenditure was for gaining assessable income, it did not take place in, or in the course of, preparing bills of cost. Further, the expenditure was of a ‘private or domestic’ nature. This seminal taxation decision, which prevents deductions for childcare, has broad financial ramifications for workers in the home and those with childcare responsibilities. It designates childcare duties as ‘private’, notwithstanding the need for these in order, particularly for women, to work in the public sphere.
