Economic transition and the distributions of income and wealth
Using a model of wealth distribution dynamics and occupational choice, the author investigates the distributional consequences of policies and developments associated with the transition from central planning to a market system. The model suggests that even an efficient privatization designed to be egalitarian may lead to increases in inequality (and possibly poverty), both during the transition and in the new steady state. Creating new markets in services that are also supplied by the public sector may also contribute to an increase in inequality. So can labor market reforms that lead to a decompression of the earnings structure and to greater flexibility in employment. The results underline the importance of retaining government provision of basic public goods and services, removing barriers that prevent the participation of the poor in the new private sector, and ensuring that suitable safety nets are in place.Environmental Economics&Policies,Economic Theory&Research,Banks&Banking Reform,Fiscal&Monetary Policy,Labor Policies,Banks&Banking Reform,Health Economics&Finance,Economic Theory&Research,Inequality,Environmental Economics&Policies
Distributions in motion: economic growth, inequality, and poverty dynamics
The joint determination of aggregate economic growth and distributional change has been studied empirically from at least three different perspectives. A macroeconomic approach that relies on cross-country data on poverty, inequality, and growth rates has generated some interesting stylized facts about the correlations between these variables, but has not shed much light on the underlying determinants."Meso-"and microeconomic approaches have fared somewhat better. The microeconomic approach, in particular, builds on the observation that growth, changes in poverty, and changes in inequality are simply different aggregations of information on the incidence of economic growth along the income distribution. This paper reviews the evolution of attempts to understand the nature of growth incidence curves, from the statistical decompositions associated with generalizations of the Oaxaca-Blinder method, to more recent efforts to generate"economically consistent"counterfactuals, drawing on structural, reduced-form, and computable general equilibrium models.Rural Poverty Reduction,Achieving Shared Growth,Inequality,Services&Transfers to Poor,Economic Theory&Research
Total Quality Management and Public Administration â The case of Vila Real town hall
Nowadays, before starting any goods or service production process, one tries to learn something about their quality. This is an issue the customers segment is confronted with when choosing from the supply at oneâs disposal. The quality movementâs main idea is that all goods and services must achieve a maximum quality. If one is to understand this movement first one has to be able to understand the implications of its assumptions in the production process and organization. (Connor, 1997). In most countries, public administration is the sector which carries the biggest weight upon employment and one supplying most goods and services. Therefore, it cannot ignore Total Quality Management (TQM) The Portuguese Government acknowledges that "presently quality is universally recognized and accepted as the clientâs satisfaction at adequate costs and that it became an imperative for all public organizations following the customersâ growing awareness of their rightsâ(DL n.Âș 166-A/99, May 13). Portuguese local public administration is facing the challenge of having to solve new and complex problems resulting from economic, social and technologic changes. It is the purpose of this paper to go into such questions as: how can TQM be implemented in a change context in Vila Real municipality? Are there limits or favourable conditions to that implementation?
Education or Inflation? The Roles of Structural Factors and Macroeconomic Instability in Explaining Brazilian Inequality in the 1980s
This paper investigates possible explanations for the increases in inequality observed in Brazil during the 1980s. While the static decompositions of inequality by household characteristics reveal that education and race of the household head, as well as geographic location, can account for a substantial proportion of inequality levels, a dynamic decomposition suggests that changes in inequality are not explained by income or allocation effects across these groupings, but by pure within-group inequality effects. The analysis then turns to the role of macro-economic instability, and finds some significant correlation and regression coefficients which suggest a link between inflation and inequality, while poverty appears to be more strongly driven by real wages, growth and employment.Brazil, inequality decomposition, poverty, inflation and unemployment
The Measurement of Educational Inequality: Achievement and Opportunity
This paper proposes two related measures of educational inequality: one for educational achievement and another for educational opportunity. The former is the simple variance (or standard deviation) of test scores. Its selection is informed by consideration of two measurement issues that have typically been overlooked in the literature: the implications of the standardization of test scores for inequality indices, and the possible sample selection biases arising from the Program of International Student Assessment (PISA) sampling frame. The measure of inequality of educational opportunity is given by the share of the variance in test scores that is explained by pre-determined circumstances. Both measures are computed for the 57 countries in which PISA surveys were conducted in 2006. Inequality of opportunity accounts for up to 35 percent of all disparities in educational achievement. It is greater in (most of) continental Europe and Latin America than in Asia, Scandinavia, and North America. It is uncorrelated with average educational achievement and only weakly negatively correlated with per capita gross domestic product. It correlates negatively with the share of spending in primary schooling, and positively with tracking in secondary schools.educational inequality, educational achievement, inequality of opportunity
Global poverty and inequality : a review of the evidence
Drawing on a compilation of data from household surveys representing 130 countries, many over a period of 25 years, this paper reviews the evidence on levels and recent trends in global poverty and income inequality. It documents the negative correlations between both poverty and inequality indices, on the one hand, and mean income per capita on the other. It points to the dominant role of Asia in accounting for the bulk of the world's poverty reduction since 1981. The evolution of global inequality in the last decades is also described, with special emphasis on the different trends of inequality within and between countries. The statistical relationships between growth, inequality and poverty are discussed, as is the correlation between inequality and the growth elasticity of poverty reduction. Some of the recent literature on the drivers of distributional change in developing countries is also reviewed.Inequality,Achieving Shared Growth,Services&Transfers to Poor,Population Policies,Poverty Impact Evaluation
Social protection in Latin America : achievements and limitations
Social protection systems in Latin America have been transformed in the past two decades. Until the 1980s, those who were not covered by the social security arrangements available primarily in the urban formal sector received little public assistance beyond universal subsidies for some food or fuel purchases. Since the 1990s, the introduction of non-contributory social insurance programs (including"social pensions") and conditional cash transfers has substantially extended the coverage and improved the incidence of social assistance. However, the organic growth of subsidized social assistance in parallel to the older social insurance system, financed largely out of taxes on formal sector employment, has led to a dual system that is neither properly equitable nor efficient. The twin challenges that now face social protection in Latin America are to better integrate those two halves of the system, and to develop programs that promote sustainable self-reliance, by moving from"safety nets"to"opportunity ropes."Rural Poverty Reduction,Services&Transfers to Poor,Debt Markets,Insurance Law,Health Monitoring&Evaluation
Comparing metaheuristic algorithms for error detection in Java programs
Chicano, F., Ferreira M., & Alba E. (2011). Comparing Metaheuristic Algorithms for Error Detection in Java Programs. In Proceedings of Search Based Software Engineering, Szeged, Hungary, September 10-12, 2011. pp. 82â96.Model checking is a fully automatic technique for checking concurrent software properties in which the states of a concurrent system are explored in an explicit or implicit way. The main drawback of this technique is the high memory consumption, which limits the size of the programs that can be checked. In the last years, some researchers have focused on the application of guided non-complete stochastic techniques to the search of the state space of such concurrent programs. In this paper, we compare five metaheuristic algorithms for this problem. The algorithms are Simulated Annealing, Ant Colony Optimization, Particle Swarm Optimization and two variants of Genetic Algorithm. To the best of our knowledge, it is the first time that Simulated Annealing has been applied to the problem. We use in the comparison a benchmark composed of 17 Java concurrent programs. We also compare the results of these algorithms with the ones of deterministic algorithms.Universidad de MĂĄlaga. Campus de Excelencia Internacional AndalucĂa Tech.

ISPRS TC IV Mid-term Symposium â3D Spatial Information Science â The Engine of Changeâ, 1â5 October 2018, Delft, The NetherlandsThis work is part of an investigation into the use of GIS for the documentation and comprehension of medieval architectural heritage in the ancient Kingdom of Seville. The research was done in the framework of the project âSustainable guardianship of cultural heritage through digital BIM and GIS models: contribution to knowledge and social innovationâ, an interdisciplinary project focused on the applications of information technology in architectural heritage in Spain. The study case of this paper is located in the Guadalquivir valley during the period between 13th and 15th centuries. It concerns the Moorish Strip site, fortified by the Christian Kingdom of Castile with the aim of creating a barrier with the Moorish Kingdom. Its deteriorated state has led us to create a historical and spatial database in order to contribute to its conservation management plan. Apart from the historical documentation research and the data gathering, intensive fieldwork was also done to collect information about the buildings. In this paper we present a Historical SDI to investigate the hypothesis that the spatial patterns of the Moorish Band obey rules of âinter-visibilityâ control. Some analysis has been done on the site scale, such as: i) a thematic map of building material; ii) a spatiotemporal analysis; iii) the density of the distribution of towers over the territory; iv) a simulation of the territory visibility from the towers; v) the inter-visibility among towers; iv) thematic maps using attribute values. These analyses permitted us to highlight the need to create a preservation plan that should consider the network visibility system as an important value for heritage interpretation and knowledge.Spainâs Ministry of Economy and Competitiveness HAR2016â78113-
Inefficient lobbying, populism and oligarchy
This paper analyses the efficiency consequences of lobbying in a production economy with imperfect commitment. We first show that the Pareto efficiency result found for truthful equilibria of common agency games in static exchange economies no longer holds under these more general conditions. We construct a model of pressure groups where the set of e.cient truthful common-agency equilibria has measure zero. Equilibria are generally inefficient as a direct result of the existence of groups with conflicting interests, which allocate real resources to lobbying. If lobbies representing "the poor " and "the rich " have identical organizational capacities, we show that these equilibria are biased towards the poor, who have a comparative advantage in politics, rather than in production. If the pressure groups di.er in their organizational capacity, both pro-rich (oligarchic) and pro-poor (populist) equilibria may arise, all of which are inefficient with respect to the constrained optimum.
