Optimal fiscal policy in a multisector model with minimum expenditure requirements

This paper investigates optimal fiscal policy in a static multisector model. A Ramsey type planner chooses tax rates on each good type as well as spending levels on each good type subject to an exogenous total expenditure constraint and requirements that some minimum amount of spending be undertaken in each sector. It is shown that optimal policy does not equally spend in each sector but instead results in one of the minimum expenditure constraints binding.

Population age structure and private consumption in Spain

In this paper we study the effect of population age distribution upon private consumption expenditure in Spain from 1964 to 1997 using aggregate data. We obtain four main results. First, changes in the population pyramid have substantial effects upon the behaviour of private consumption. Second, the pattern of the coefficients of the demographic variables is not consistent with the simplest version of the life cycle hypothesis. Third, we estimate the impact of the demographic transition upon consumption and find positive values associated with episodes in which the shares of groups of individuals with expenditure levels higher (lower) than the mean increased (decreased). Fourth, the results are robust to alternative specifications for the population age distribution.

Foreign Aid Linked to Infrastructure and/or Pollution Abatement

This paper studies the macroeconomic effects of a permanent increase in foreign aid in a model that takes into account environmental quality. We develop a dynamic equilibrium model in which both public investment in infrastructure and environmental protection can be financed using domestic resources and international aid programs. The framework considers four scenarios for international aid: untied aid,aid fully tied to infrastructure, aid fully tied to abatement, and aid equally tied to both types of expenditures. We find that the effects of the transfers may depend on (i) the structural characteristics of the recipient country (the elasticity of substitution in production and its dependence on environment and natural resources) and on (ii) how recipient countries distribute their public expenditure. These results underscore the importance of these factors when deciding how and to what extent to tie aid to infrastructure and/or pollution abatement.

Evolución de las políticas de ayuda a la vivienda en España.

En el presente trabajo se estudia la evolución del gasto público en la política de vivienda en España. La política de vivienda constituye una parte más de la Economía del Bienestar, aunque no ha recibido la misma atención que otros de sus componentes, como la salud, la educación o las pensiones. Comenzaremos situando a España en el contexto europeo y observaremos como los efectos de la crisis internacional han afectado de manera significativa a las partidas de gasto de este bien. Conoceremos cuáles son los principales objetivos e instrumentos de la política de vivienda en España y analizaremos la evolución de la misma. De este modo, se detallarán los Planes de Vivienda que se han ido elaborando desde comienzos del siglo XX hasta nuestros días. A continuación, evaluaremos la situación en la que nos encontramos en base a algunas características del mercado de vivienda. Para finalizar, se cierra el trabajo estableciendo una serie de conclusiones breves y unas posibles propuestas de mejora o posibles caminos a seguir.

Los Gastos Fiscales en España en los últimos años.

En este trabajo se realiza un análisis de los gastos fiscales en España durante los últimos 10 años. Para ello se parte de la definición y características de estos pasando por sus ventajas e inconvenientes, sus tres métodos de estimación del mismo y el utilizado en España, contextualizándolo en el marco legal básico del que emana los Presupuestos Generales del Estado. Continuamos abordando los gastos fiscales a través de tres puntos de vista diferentes: Presupuestario, donde se analizan los gastos fiscales a través de los Beneficios Fiscales y del Presupuesto de Ingresos. Por Políticas de Gasto, donde estos son analizados a través de las políticas a los que son destinados dichos gastos. Y finalmente, desde el punto de vista Impositivo, donde se analizan a través de cada impuesto individualmente en que elemento del impuesto se recogen dichos Beneficios Fiscales relacionándolos con las políticas de gasto a los que son destinados.

Uptake and factors that influence the use of 'sit less, move more' occupational intervention strategies in Spanish office employees

Background: Little is known about the types of 'sit less, move more' strategies that appeal to office employees, or what factors influence their use. This study assessed the uptake of strategies in Spanish university office employees engaged in an intervention, and those factors that enabled or limited strategy uptake. Methods: The study used a mixed method design. Semi-structured interviews were conducted with academics and administrators (n = 12; 44 +/- 12 mean SD age; 6 women) at three points across the five-month intervention, and data used to identify factors that influenced the uptake of strategies. Employees who finished the intervention then completed a survey rating (n = 88; 42 +/- 8 mean SD age; 51 women) the extent to which strategies were used [never (1) to usually (4)]; additional survey items (generated from interviewee data) rated the impact of factors that enabled or limited strategy uptake [no influence (1) to very strong influence (4)]. Survey score distributions and averages were calculated and findings triangulated with interview data. Results: Relative to baseline, 67% of the sample increased step counts post intervention (n = 59); 60% decreased occupational sitting (n = 53). 'Active work tasks' and 'increases in walking intensity' were the strategies most frequently used by employees (89% and 94% sometimes or usually utilised these strategies); 'walk-talk meetings' and ` lunchtime walking groups' were the least used (80% and 96% hardly ever or never utilised these strategies). 'Sitting time and step count logging' was the most important enabler of behaviour change (mean survey score of 3.1 +/- 0.8); interviewees highlighted the motivational value of being able to view logged data through visual graphics in a dedicated website, and gain feedback on progress against set goals. 'Screen based work' (mean survey score of 3.2 +/- 0.8) was the most significant barrier limiting the uptake of strategies. Inherent time pressures and cultural norms that dictated sedentary work practices limited the adoption of 'walk-talk meetings' and ` lunch time walking groups'. Conclusions: The findings provide practical insights into which strategies and influences practitioners need to target to maximise the impact of 'sit less, move more' occupational intervention strategies.

El control del gasto público en España

En español:El sector público gestiona una gran cantidad de recursos para satisfacer las demandas de la sociedad de bienes y servicios públicos, como sanidad, educación, prestaciones sociales, etc. Y, cada vez más, se reclama por parte de los ciudadanos una utilización eficaz, y eficiente de dichos recursos. Es por ello que el papel de las instituciones que realizan el control del gasto público adquiere una importancia relevante. Este trabajo tiene como objetivo analizar cómo se lleva a cabo el control del gasto público en España, analizando los diferentes niveles de control, así como las instituciones que lo realizan y las relaciones existentes entre ellas, pudiendo constatar la necesidad de coordinación entre ellas para que los recursos que se destinan a la función de control no sean utilizados ineficientemente.

The Spanish Pension System: Overview and Long-Term Projections

In the middle of the so-called pension crisis, the ageing of population and the sharp decrease in affiliations to Social Security are threatening the well-functioning of the Spanish public pension system. The purpose of this paper is to present the main challenges to be faced by the Spanish pension system, as well as to shed light on the main determinants that will condition the evolution of pension expenditure over GDP along the following decades. This quantitative analysis, which considers the 2011 and 2013 pension reforms, uses the latest data on the Spanish demographic, labor market and institutional factors in order to project the evolution of the system from the expenditure side up to 2060. For the purpose of analyzing the dynamics and the underlying drivers of pension expenditure, the so-called aggregate accounting approach will be utilized. The alternative scenarios proposed allow for exploring the robustness of the results within the baseline scenario, which constitutes the reference point of projections in the exercise. The analysis concludes that, by the end of the projected period, Spain will count on a similar public pension expenditure ratio as the current one.
