Absolute and Relative Deprivation and the Measurement of Poverty 总被引:2,自引:0,他引:2
This paper develops the link between poverty and inequality by focussing on a class of poverty indices (some of them well–known) which aggregate normative concerns for absolute and relative deprivation. The indices are distinguished by a parameter value that captures the ethical sensitivity of poverty measurement to "exclusion" or "relative–deprivation" aversion. The indices can be readily used to predict the impact of growth on poverty. An illustration using LIS data finds that the United States show more relative deprivation than Denmark and Belgium whatever the percentiles considered, but that overall deprivation comparisons of the four countries considered will generally depend on the intensity of the ethical concern for relative deprivation. The impact of growth on poverty also depends on the presence of and on the attention granted to concerns over relative deprivation. 相似文献

The paper proposes an indicator of the performance of a tax and benefit system in generating a high level of social welfare. Under standard assumptions on the form of the admissible social welfare functions, the indicator is shown to be increasing in the progressivity of the system. Using UK household data for 1985, the paper asks (i) What can the performance of a tax system with constant residual progression be? (ii) Relative to a proportional system, what is the performance of existing or proposed tax and benefit systems? (iii) How can we estimate the average residual progression of unevenly progressive tax and benefit systems? 相似文献

This paper proposes a methodology for testing for whether tax reforms are pro-poor. This is done by extending stochastic dominance techniques to identify tax reforms that will be deemed absolutely or relatively pro-poor by a wide spectrum of poverty analysts. The statistical properties of the various estimators are also derived in order to make the method implementable using survey data. The methodology is used to assess the pro-poorness of possible reforms to Mexico’s indirect tax system. This leads to the identification of several possible pro-poor tax reforms in that country. It also shows how the pro-poorness of a tax reform depends on one’s conception of poverty as well as on the revenue and efficiency impact of the reform. 相似文献

Just as the Gini inequality index captures people's relative deprivation (Yitzhaki, 1979), so, we show in this paper, Gini-based progressivity and horizontal inequity indices capture individual perceptions of relative fiscal harshness and ill-fortune. In fact, we find that these links between individualistic perceptions and the measurement of the distribution and redistribution of income generalise to the family of indices based on the extended Ginis of Donaldson and Weymark (1980) and Yitzhaki (1983). Through 'leaky bucket' experiments, we also suggest how we can parameterise the inequality aversion present in these indices. Analysis of the Canadian gross and net income distributions (conducted using recently developed statistical inference procedures) shows the distribution and the aggregation of these individual indicators of relative deprivation, fiscal harshness and ill-fortune in 1981 and in 1990. 相似文献

This paper proposes techniques to test for whether growth has been pro-poor. We first review different definitions of pro-poorness and argue for the use of methods that can generate results that are robust over classes of pro-poor measures and ranges of poverty lines. We then provide statistical procedures that rely on the use of sample data to infer whether growth has been pro-poor in a population. We apply these procedures to Mexican household surveys for 1992, 1998, and 2004. We find strong normative and statistical evidence that Mexican growth has been absolutely anti-poor between 1992 and 1998, absolutely pro-poor between 1998 and 2004 and between 1992 and 2004, and relatively pro-poor between 1992 and 2004 and between 1998 and 2004. The relative assessment of the period between 1992 and 1998 is statistically too weak to lead to a robust evaluation of that period. 相似文献

Abstract The paper proposes and applies statistical tests for poverty dominance that check for whether poverty comparisons can be made robustly over ranges of poverty lines and classes of poverty indices. This helps provide both normative and statistical confidence in establishing poverty rankings across distributions. The tests, which can take into account the complex sampling procedures that are typically used by statistical agencies to generate household‐level surveys, are implemented using the Canadian Survey of Labour and Income Dynamics (SLID) for 1996, 1999, and 2002. Although the yearly cumulative distribution functions cross at the lower tails of the distributions, the more recent years tend to dominate earlier years for a relatively wide range of poverty lines. Failing to take into account SLID’s sampling variability (as is sometimes done) can inflate significantly one’s confidence in ranking poverty. Taking into account SLID’s complex sampling design (as has not been done before) can also decrease substantially the range of poverty lines over which a poverty ranking can be inferred. 相似文献

When comparing poverty across distributions, an analyst must select a poverty line to identify the poor, an equivalence scale to compare individuals from households of different compositions and sizes, and a poverty index to aggregate individual deprivation into an index of total poverty. A different choice of poverty line, poverty index or equivalence scale can of course reverse an initial poverty ordering. This paper develops easily-checked sequential stochastic dominance conditions that throw light on the robustness of poverty comparisons to these important measurement issues. These general conditions extend well-known results to any order of dominance, to the choice of individual versus family based aggregation, and to the estimation of "critical sets" of measurement assumptions. Our theoretical results are briefly illustrated using data for four countries drawn from the Luxembourg Income Study databases. 相似文献

The paper contributes to the measurement of poverty and vulnerability in three ways. First, it proposes a new approach to separating poverty into chronic and transient components. Second, it provides corrections for the statistical biases introduced when using a small number of periods to estimate the importance of vulnerability and transient poverty. Third, it applies these tools to the measurement of chronic and transient poverty in China using a rich panel data set that extends over 17 years. Alternative measurement techniques are found to yield significantly different estimates of the relative importance of chronic and transient poverty. The precision of the estimates is also considerably enhanced by simple statistical corrections. 相似文献

The dividend-price ratio and expectations of future dividends and discount factors 总被引:27,自引:0,他引:27
A dividend-ratio model is introduced here that makes the logof the dividend-price ratio on a stock linear in optimally forecastfuture one-period real discount rates and future one-periodgrowth rates of real dividends. If ex post discount rates areobservable, this model can be tested by using vector autoregressivemethods. Four versions of the linearized model, differing inthe measure of discount rates, are tested for U.S. time series1871-1986 and 1926-1986: a version that imposes constant realdiscount rates, and versions that measure discount rates fromreal interest rate data, aggregate real consumption data, andreturn variance data. The results yield a metric to judge therelative importance of real dividend growth, measured real discountrates, and unexplained factors in determining the dividend-priceratio. 相似文献
