Gravitational wave detection by a spherical antenna: the angular sensitivity of resonators in the TIGA configuration and its variation with sidereal time and galactic longitude

Experimental projects using spherical antennas to detect gravitational waves are nowdays a concrete reality. The main purpose of this paper is to give a possible way of interpreting output data from such a system. Responses of the five fundamental quadrupole modes and of the six resonators in TIGA collocations are shown as a function of the incoming direction of the incident wave. Then, for a source lying in the galactic plane, sidereal time and galactic longitude dependence is given. Thus, once a candidate source of gravitational waves is considered, we can exactly predict the resonators' response as a function of time.Comment: 30 pages, 7 figure

Argentina´s Distributional Failure: The role of Integration and Public Policies

This paper documents the income distribution changes experienced by Argentina during the last decades. Inequality substantially increased, and despite economic growth during some periods, poverty also went significantly up. Two types of episodes have shaped Argentina’s income distribution: deep macroeconomic crisis and periods of openness and integration. The sizeable raise in inequality in the 90s seems to be associated to reallocations against unskilled-labor intensive sectors, and especially to skilled-biased technological change within most sectors, both factors stimulated by the process of economic integration. The depth and speed of the reforms and the absence of public policies to ease the transition contributed to the particular severity of the income distribution changes in Argentina.inequality, distribution, globalization, integration, wages, education, Argentina

Income Inequality in Latin America and the Caribbean: Evidence from Household Surveys

This paper reports information on income inequality in Latin America and the Caribbean computed from a sample of more than 50 household surveys from 20 LAC countries from 1989 to 2001. Although the core of the statistics is on household income inequality, we also report results on aggregate welfare and polarization. Inequality has moderately increased in South America in the last decade. The two main exceptions are Argentina, with a very large inequality increase, and Brazil, where inequality actually decreased. Changes have not been significant in Central America and the Caribbean. Aggregate welfare has increased in most countries fueled by economic growth and despite unequalizing distributional changes.inequality, distribution, income, wages, education, Latin America, Caribbean.

Assessing benefit-incidence results using decompositions. The case of health policy in Argentina.

This paper discusses the use of aggregate and microeconometric decompositions to compare benefit-incidence results over time. Decompositions are applied to explore changes in targeting in health policies directed to pregnant women and children under 4 in Argentina. The results suggest that although health public programs are pro-poor, incidence changes in the period 1997-2001 were pro-rich due to at least two factors: a substantial reduction in the fertility rate of poor couples, and an increase in the use of public facilities by wealthier households, likely triggered by the economic crisis.Argentina

Assessing Benefit-Incidence Results Using Decompositions: The Case of Health Policy in Argentina

This paper discusses the use of aggregate and microeconometric decompositions to compare benefit-incidence results over time and across regions. Decompositions are applied to explore changes in targeting in health policies directed to pregnant women and children under 4 in Argentina. The results suggest that although health public programs are pro-poor, incidence changes in the last 5 years have been pro-rich due to two different factors: a substantial reduction in the fertility rate of poor couples, and an increase in the use of public facilities by wealthier households, likely triggered by the economic crisis that Argentina has suffered since 1998.protección, informalidad, empleo, América Latina.

Tracing out the Effects of Demographic Changes on the Income Distribution. The Case of Greater Buenos Aires 1980-2000

During the last two decades fertility decisions have varied significantly and not uniformly along the income distribution. In this paper we study the effects of these demographic changes on two dimensions of the income distribution -poverty and inequality- by applying microeconometric decompositions techniques. In particular, we simulate the equivalized household income distribution that would emerge if individuals in time t took fertility decisions as in time t’. The results suggest that these demographic factors can account for a of the actual increase in poverty and inequality between 1980 y 1992.demography, fertility, income distribution, poverty, inequality, Argentina, Greater Buenos Aires, decompositions

Estimating Income Poverty and Inequality from the Gallup World Poll: The Case of Latin America and the Caribbean

This paper takes advantage of a new source of information – the Gallup World Poll 2006 – to estimate and characterize income poverty and inequality in Latin America and the Caribbean (LAC) at the country level, and to compare LAC estimates to those in other regions of the world. The Gallup survey has the advantage of being conducted in over 130 nations with almost the same questionnaire in all countries, and then it stands as a complement to national household surveys for international comparison purposes.poverty, inequality, incomes, Latin America, Caribbean, Gallup

Meeting the Poverty-Reduction MDG in the Southern Cone

This paper assesses the likelihood of meeting the Millennium Development Goal of halving poverty by 2015 in Argentina, Chile, Paraguay and Uruguay. We simulate the poverty impact of changes in growth rates and redistributive policies, and trace the poverty consequences of various alternative economic scenarios using microeconometric decompositions. Sustainable and vigorous productivity growth seems to be a necessary condition to meet the poverty MDG by 2015 in Argentina, Paraguay and Uruguay. The required growth rate could be significantly lower if some modest well-targeted redistribution could be performed. In contrast to its neighbors, Chile has already achieved the poverty MDG.MDG, poverty, Argentina, Chile, Paraguay, Uruguay
