A recent study in Kogi State of Nigeria revealed that poverty is higher among households that have male heads, are polygamous, have farming as the only occupation, have no formal education, and have no access to extension services and improved farming inputs. Poverty rises with the increase in household size and dependency ratio. On the other hand, poverty is inversely related to the extent of output commercialization, farm size, and credit. The study indicates that in Kogi State, Nigeria there is the need to reduce birth rate, provide training and education, and improve farming inputs, credit to deserving households, and marketing infrastructures, as major elements of an effective poverty reduction strategy.","PeriodicalId":142300,"journal":{"name":"Journal of Income Distribution®","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122478681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most widely known of these models are the Pareto, log-normal, generalized log-normal, generalized Gamma, generalized Beta of the first and of the second kind, the Dagum, and the Singh-Madala distributions. They are discussed as a group in this note, as general forms of income distributions. Several well-known models are derived from them as sub-families with interesting applications in economics. The behaviour of their entropy is what is here under study. Maximum entropy formalism chooses certain forms of entropy and derives an exponential family of distributions under certain constraints. Finding constraints that income distributions have maximum entropy is another direction of this note. In economics and social statistics, the size distribution of income is the basis of concentration on the Lorenz curve. The difference between the tail of the Lorenz function and the Lorenz function itself determines the entropy of mixing. In the final section of this note, theoretical properties of well-known income distributions are also derived in view of the entropy of mixing.","PeriodicalId":142300,"journal":{"name":"Journal of Income Distribution®","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128178561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study we assess the performance of functional forms proposed by Kakwani (1980a) and Villasenor and Arnold(1989) to estimate the Lorenz curve from grouped data. The methods are implemented using the computational tools POVCAL and Sim-SIP, developed and distributed by the World Bank. To identify biases associated with these methods, we use unit data from several household surveys and theoretical distributions. We find that poverty and inequality are better estimated when the true distribution is unimodal than multimodal. For unimodal distributions, biases associated with poverty measures are rarely larger than one percentage point. For data from multi-peaked or heavily skewed distributions, the biases are likely to be higher and of unknown sign.","PeriodicalId":142300,"journal":{"name":"Journal of Income Distribution®","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133389972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The correlation may be due to inherited, economic, and/or contextual factors. A structural model is proposed in which parents affect their children directly through their own schooling and earnings and indirectly through their own inherited ability. By taking account of inherited ability, the causal effect on outcome of parental schooling and earnings upon the schooling and earnings of their children is identified. A generated regressor methodology is used to estimate the ability to learn and earn of Israeli parents. It is shown that the schooling and earnings of children are affected by these generated regressors. Further, although the causal effects are small, it is shown that parents’ income and schooling matter for their children’s schooling and earnings. Both nature and nurture are reflected in the intergenerational correlation for schooling and earnings, but nature and contextual variables turn out to matter more than nurture.","PeriodicalId":142300,"journal":{"name":"Journal of Income Distribution®","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126858008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

IDA is a matched savings program designed to help low-income households invest in appreciating assets. For these households, the risk involved with participation in IDA relates to the sacrifice they make by reducing current consumption - sometimes in a significant way - in order to be able to save. The program does not offer a match on savings per se; rather, it offers the match only when savings are invested in certain assets. Since there is no guarantee that IDA savings will be converted into assets qualified for the IDA match at the time of enrollment, participation in the program is characterized as an inherently risky decision, which is governed by different sets of behavioral factors, including the risk-taking preferences of low-income households. Consideration of risk provides an alternative explanation for issues related to program take-up, inactivity, and attrition rates. It also offers new and simple ideas on how to improve results. In addressing these problems, the article recommends using an IDA model that includes a flexible match component, to insure against the risk of unmatched savings and complement the existing IDA match structure. Simple modifications to current policy will maintain the total cost of IDA match at the existing levels. Introduction of a flexible match may mitigate the risk of decision to participate in IDA for the most vulnerable group of participants. It can also potentially reduce the percentage of inactive accounts while improving the overall retention rates in the program. Moreover, the recommended changes would not alter the nature of the IDA program, as the flexible match would only amount to a fraction of the total asset investment match.","PeriodicalId":142300,"journal":{"name":"Journal of Income Distribution®","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125735003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We seek to develop greater understanding about actual lifetime earnings patterns to compare with hypothetical workers and find discrepancies which lead typical hypothetical workers to produce a more favorable impression for defined-contribution pension reforms. We suggest modifications to make a more suitable hypothetical worker.","PeriodicalId":142300,"journal":{"name":"Journal of Income Distribution®","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129549616","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To date, Fogelson and Kutsche (1961) and Finger (1984) have identified the continuation of a communal, labor-sharing, agricultural institution called the gadugi as an example of Cherokee agency during a period of substantial upheaval. I contribute to the historiography on ancestral labor traditions by adopting Kimball’s (1988) framework on the function of farming cooperatives to test whether this arrangement sprung up as a form of insurance against the idiosyncratic risk inherent in southern agriculture. Data collected from the 1850-1880 manuscript census returns on North Carolina Cherokee farms are used to compute the variance of household self-sufficiency, which appears substantial enough to warrant a non-market mechanism to pool risk.","PeriodicalId":142300,"journal":{"name":"Journal of Income Distribution®","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128844046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
