The NEP-LTV Blog

September 27, 2010

This blog is an experiment to explore the feasibility of scientific discussion on an Economics blog. NEP-LTV disseminates every week new working papers in the field of Unemployment, Inequality & Poverty. Among them, the NEP-LTV editor selects one to be discussed. Everyone is invited to comment. Try to stay civil, or your comments will be removed. And encourage others to read or join in the discussion.


Challenges to promoting social inclusion of the extreme poor: evidence from a large scale experiment in Colombia By: Laura Abramovsky (Institute for Fiscal Studies) ; Orazio Attanasio (Institute for Fiscal Studies and University College London) ; Kai Barron (Institute for Fiscal Studies and University College London) ; Pedro Carneiro (Institute for Fiscal Studies and cemmap and UCL) ; George Stoye (Institute for Fiscal Studies)

We evaluate the large scale pilot of an innovative and major welfare intervention in Colombia, which combines homes visits by trained social workers to households in extreme poverty with preferential access to social programs. We use a randomized control trial and a very rich dataset collected as part of the evaluation to identify program impacts on the knowledge and take-up of social programs and the labor supply of targeted households. We find no consistent impact of the program on these outcomes, possibly because the way the pilot was implemented resulted in very light treatment in terms of home visits. Importantly, administrative data indicates that the program has been rolled out nationally in a very similar fashion, suggesting that this major national program is likely to fail in making a significant contribution to reducing extreme poverty. We suggest that the program should undergo substantial reforms, which in turn should be evaluated.

Partial insurance and investments in children By: Pedro Carneiro (Institute for Fiscal Studies and cemmap and UCL) ; Rita Ginja (Institute for Fiscal Studies and University of Uppsala)

August 17, 2015

This paper studies the impact of permanent and transitory shocks to income on parental investments in children. We use panel data on family income, and an index of investments in children in time and goods, from the Children of the National Longitudinal Survey of Youth. Consistent with the literature focusing on non-durable expenditure, we find that there is only partial insurance of parental investments against permanent income shocks, but the magnitude of the estimated responses is small. We cannot reject the hypothesis full insurance against temporary shocks. Another interpretation of our findings is that there is very little insurance available, but the fact that skill is a non-separable function of parental investments over time results in small reactions of these investments to income shocks, especially at later ages.

Keywords: Insurance; human capital; consumption

Poor Little Rich Kids? The Determinants of the Intergenerational Transmission of Wealth By: Black, Sandra E. (University of Texas at Austin) ; Devereux, Paul J. (University College Dublin) ; Lundborg, Petter (Lund University) ; Majlesi, Kaveh (Lund University)

Wealth is highly correlated between parents and their children; however, little is known about the extent to which these relationships are genetic or determined by environmental factors. We use administrative data on the net wealth of a large sample of Swedish adoptees merged with similar information for their biological and adoptive parents. Comparing the relationship between the wealth of adopted and biological parents and that of the adopted child, we find that, even prior to any inheritance, there is a substantial role for environment and a much smaller role for genetics. We also examine the role played by bequests and find that, when they are taken into account, the role of adoptive parental wealth becomes much stronger. Our findings suggest that wealth transmission is not primarily because children from wealthier families are inherently more talented or more able but that, even in relatively egalitarian Sweden, wealth begets wealth.

Keywords: intergenerational mobility, nature versus nurture, portfolio allocation

Do More of Those in Misery Suffer from Poverty, Unemployment or Mental Illness? By: Flèche, Sarah (CEP, London School of Economics) ; Layard, Richard (London School of Economics)

August 17, 2015

Studies of deprivation usually ignore mental illness. This paper uses household panel data from the USA, Australia, Britain and Germany to broaden the analysis. We ask first how many of those in the lowest levels of life-satisfaction suffer from unemployment, poverty, physical ill health, and mental illness. The largest proportion suffer from mental illness. Multiple regression shows that mental illness is not highly correlated with poverty or unemployment, and that it contributes more to explaining the presence of misery than is explained by either poverty or unemployment. This holds both with and without fixed effects.

Keywords: mental health, life-satisfaction, wellbeing, poverty, unemployment

Pricing Genius: The Market Evaluation of Innovation By: David Galenson (University of Chicago) ; Simone Lenzu (University of Chicago)

August 10, 2015

Economists have neglected a key issue for understanding and increasing technological change, in failing to study how talented individuals produce innovations. This paper takes a quantitative approach to this problem. Regression analysis of auction data from 1965-2015 reveals that the age-price profiles of Jackson Pollock and Andy Warhol – the two greatest painters born in the 20th century – closely resemble the age profiles of the two artists derived both from textbooks of art history and from retrospective exhibitions. The agreement of these sources confirms that the auction market assigns the highest prices to the most important art, and examination of the artists’ careers reveals that this art is the most important because it is the most innovative. These results lend strong support to our understanding of creativity at the individual level, with a sharp contrast between the extended experimental innovation of Pollock and the sudden conceptual innovation of Warhol.

Aggregating Elasticities:\ Intensive and Extensive Margins of Female Labour Supply By: Attanasio, Orazio ; Levell, Peter ; Low, Hamish ; Sánchez-Marcos, Virginia

August 10, 2015

There is a renewed interest in the size of labour supply elasticities and the discrepancy between micro and macro estimates. Recent contributions have stressed the distinction between changes in labour supply at the extensive and the intensive margin. In this paper, we stress the importance of individual heterogeneity and aggregation problems. At the intensive margins, simple specifications that seem to fit the data give rise to non linear expressions that do not aggregate in a simple fashion. At the extensive margin, aggregate changes in participation are likely to depend on the cross sectional distribution of state variables when a shock hits and, therefore, are likely to be history dependent. We tackle these aggregation issues directly by specifying a life cycle model to explain female labour supply in the US and estimate its various components. We estimate the parameters of different component of the model. Our results indicate that (i) at the intensive margin, Marshallian and Hicksian elasticities are very heterogeneous and, on average, relatively large; (ii) Frisch elasticities are, as implied by the theory, even larger; (iii) aggregate labour supply elasticities seem to vary over the business cycle, being larger during recessions.
Keywords: aggregation; heterogeneity; labour supply elasticities; non-separability

Job Quality in Segmented Labor Markets: The Israeli Case By: Neuman, Shoshana

August 10, 2015

Till the early-1990s the collectively-bargained labor contract (between the trade-union that presented the employees, and the employer or the employers’-association) was the norm, granting salaried workers a stable and protected labor contract. Thereafter, and more significantly after 1995, the share of unionized workers dropped constantly, to almost half of its peak level (of more than 80 percent). In parallel, two other types of contracts became more common: personal temporary contracts (between an individual worker and his employer), and contracts between a labor-contractor and employees who are employed in a triangular mode of employment (employee-contractor-client). The latter involves precarious employment and is more common among the more vulnerable sub-populations of new-immigrants, disabled individuals, Israeli-Arabs, foreign-workers and women. The contractual changes resulted in work instability, growth of the secondary labor market and segmentation. Efforts to protect the disadvantaged secondary labor-market workers include legislation, reforms, new regulations, and enforcement of all the above.

Keywords: collective bargaining; contracted labor; foreign workers; immigrants; Israel; labor contracts; labor market segmenting; regulation
