Wealth distribution, peasant production and poverty traps in African smallholder agriculture

Hoogeveen, Johannes - 1999

A model is developed for peasant households in land abundant areas who choose between two technologies for land preparation: a manual one and one using draught animals. For draught a minimum number of animals is required so that a technological non convexity exists. It follows that certain...

A new inequality measure that is sensitive to extreme values and asymmetries

McAleer, Michael; Ryu, Hang-keun; Slottje, Daniel Jonathan - 2017

properties such a measure (or index) should contain. The Gini index is, of course, the most popular. There is a concurrent … Gini) that poorly detect the extreme values present in the underlying empirical IDF. This paper introduces a new inequality … measure to supplement, but not to replace, the Gini that measures more accurately the inherent asymmetries and extreme values …

Combining panel data sets with attrition and refreshment samples

Hirano, Keisuke; Imbens, Guido; Ridder, Geert; Rubin, … - 1998

With panel data important issues can be resolved that can not beaddressed with cross--sectional data. A major drawback is that paneldata suffer from more severe missing data problems. Adding a sampleconsisting of new units randomly drawn from the original populationas replacements for units who...

On a simple survey measure of individual risk aversion

Hartog, Joop; Ferrer-i-Carbonell, Ada; Jonker, Nicole - 2000

We ask individuals for their reservation price of a specified lotteryand deduce their Arrow-Pratt measure of risk aversion.This allows direct testing of common hypotheses on risk attitudes inthree datasets. We find that risk aversion indeed fallswith income and wealth. Entrepreneurs are less...

Empirical relevance of the Hillman condition and comparative advantage

Hinloopen, Jeroen; Marrewijk, Charles van - 2004

We analyze the empirical violation of the Hillman condition, a necessary and sufficient condition for the correspondence between comparative advantage and pre-trade relative prices. Our comprehensive data set allows us to investigate the Hillman condition for virtually all countries of the...

Bayesian mode inference for discrete distributions in economics and finance

Cross, Jamie; Hoogerheide, Lennart; Labonne, Paul; … - 2023

Detecting heterogeneity within a population is crucial in many economic and financial applications. Econometrically, this requires a credible determination of multimodality in a given data distribution. We propose a straightforward yet effective technique for mode inference in discrete data...

Estimating income inequality in China using grouped data and the generalized beta distribution

Chotikapanich, Duangkamon; Prasada Rao, D. S.; Tang, Kam Ki - 2006

There are two main types of data sources of income distributions in China: household survey data and grouped data. Household survey data are typically available for isolated years and individual provinces. In comparison, aggregate or grouped data are typically available more frequently and...

Chotikapanich, Duangkamon; Prasada Rao, D. S.; … - 2007

This paper examines the nature and extent of global and regional income distribution and inequality using the most recent country level data on income distribution drawn from World Bank and UNU-WIDER studies for the period 1993-2000. The methodology used is a recently developed technique to fit...

On positive value of information in risk sharing

Denderski, Piotr; Stoltenberg, Christian - 2015 - This Version: May 2015

We develop a novel argument why better public information can help countries to insure against idiosyncratic risk. Representative agents of developing and industrial countries receive public and private signals on their future income realization and engage in risk-sharing contracts with limited...

The bias of the Gini coefficient due to grouping

Van Ourti, Tom; Clarke, Philip M. - 2008

We propose a first order bias correction term for the Gini index to reduce the bias due to grouping. The first order … correction term is obtained from studying the estimator of the Gini index within a measurement error framework. In addition, it …
