The Covariance Structure of East and West German Incomes and its Implications for the Persistence of Poverty and Inequality

Biewen, Martin - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2002

persistence of transitory shocks and their implications for the persistence of poverty and income inequality. The results suggest … that 52 to 69 percent of income inequality in West Germany were due to permanent differences between individuals and that … to overall income inequality increased from 20 percent in 1990 to over 70 percent in 1998 and the persistence of poverty …

Estimating Alternative Technology Sets in Nonparametric Efficiency Analysis: Restriction Tests for Panel and Clustered Data

Neumann, Anne; Nieswand, Maria; Schubert, Torben - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2013

Nonparametric efficiency analysis has become a widely applied technique to support industrial benchmarking as well as a variety of incentive- based regulation policies. In practice such exercises are often plagued by incomplete knowledge about the correct specifications of inputs and outputs....

The Bootstrap and the Edgeworth Correction for Semiparametric Averaged Derivatives

Nishiyama, Yoshihiko; Robinson, Peter M - Suntory and Toyota International Centres for Economics … - 2005

In a number of semiparametric models, smoothing seems necessary in order to obtain estimates of the parametric component which are asymptotically normal and converge at parametric rate. However, smoothing can inflate the error in the normal approximation, so that refined approximations are of...

Robustness of bootstrap in instrumental variable regression

Camponovo, Lorenzo; Otsu, Taisuke - Suntory and Toyota International Centres for Economics … - 2014

This paper studies robustness of bootstrap inference methods for instrumental variable (IV)regression models. We consider test statistics for parameter hypotheses based on the IV estimatorand generalized method of trimmed moments (GMTM) estimator introduced by Cížek (2008, 2009),and compare...

Bootstrap Tests of Stochastic Dominance with AsymptoticSimilarity on the Boundary

Linton, Oliver; Song, Kyungchul; Whang, Yoon-Jae - Suntory and Toyota International Centres for Economics … - 2008

We propose a new method of testing stochastic dominance which improves onexisting tests based on bootstrap or subsampling. Our test requires estimation ofthe contact sets between the marginal distributions. Our tests have asymptoticsizes that are exactly equal to the nominal level uniformly over...

Accounting for Poverty Differences between the United States, Great Britain, and Germany

Biewen, Martin; Jenkins, Stephen P. - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2002

We propose a framework for comparing the relationship between poverty and personal characteristics across countries (or across years), and use it to compare levels and patterns of relative poverty in the USA, Great Britain and Germany during the 1990s. The higher aggregate poverty rates in the...

The Measurement of Poverty: An Experimental Questionnaire Investigation (published in Economic Letters, vol.22 (1997), pp.571-588)

Amiel, Yoram; Cowell, Frank A - Suntory and Toyota International Centres for Economics … - 1994

We re-examine some of the standard axioms used in the literature on Poverty Measurement. Using a sample of 486 students from Australia, Israel and the USA we investigate the extent to which perceptions of poverty correspond to the axioms.

Robustness properties of poverty indices

Cowell, Frank A; Victoria-Feser, Maria-Pia - Suntory and Toyota International Centres for Economics … - 1994

Drawing on recent work concerning the statistical robustness of inequality statistics we examine the sensitivity of … poverty indices to data contamination using the concept of the influence function. We show that poverty and inequality indices …
