Wage effects of non-wage labour costs

We study wage effects of two important elements of non-wage labour costs: firing costs and payroll taxes. We exploit a reform that introduced substantial reduction in these two provisions for unemployed workers aged less than thirty and over forty five years. Theoretical insights are gained with a matching model with heterogeneous workers, which predict a positive effect on wages for new entrant workers but an ambiguous effect for incumbent workers. Difference-in-differences estimates, which account for the endogeneity of the treatment status, are consistent with our model predictions and suggest that decreased firing costs and payroll taxes have a positive effect on wages of new entrants. We find larger effects for older than for younger workers and for men than for women. Calibration and simulation of the model corroborate such positive effect for new entrants and also show a positive wage effect for incumbents. The reduction in firing costs accounts, on average, for one third of the overall wage increase.Dismissal costs, payroll tax, evaluation of labour market reforms, difference-in-difference, matching model, Spain

Estimating the income loss of disabled individuals: The case of Spain

In this paper, we present both a theoretical and an empirical model in order to identify the effects of disability on wages. In the theoretical model we assume that the wage gap of a disabled worker depends on a permanent and a transitory productivity gap and the model predicts that the wage gap will be lower after gaining some work experience in the new job. We test this theoretical hypothesis using an exogenous health shock and matching methods associated with treatment effect techniques for policy evaluation. In all our specifications, we find that the reduction of the wage for the disabled is between 293 and 342 euros per month expressed in constant terms at 2010 prices (21-24% of the average wage of disabled workers) but this reduction is more than offset when we take into account both the disability benefits and the wage. As predicted in the theoretical model, we observe that the pay gap between the disabled and the non-disabled individuals falls over time once the transitory drop in productivity is disappearing. However, we observe a constant wage gap that remains over time and that corresponds to the permanent fall in productivity predicted by the theoretical model

Diversidade genética de bovinos de corte por meio de marcadores microssatélites.

Uma alternativa para atender a demanda do mercado por carne de qualidade é a utilização de cruzamentos entre raças zebuínas e taurinas adaptadas. Assim, as raças Bonsmara, Caracu e Senepol (taurinas adaptadas), Angus (taurina não-adaptada) e Nelore (zebuína) foram analisadas utilizando cinco marcadores microssatélites para avaliar a diversidade genética existente dentro e entre as raças e orientar a sua utilização em cruzamentos. Foram analisados 127 touros Bonsmara, Caracu, Senepol, Angus e Nelore e as frequências alélicas foram utilizadas para estimar diversidade gênica, conteúdo de polimorfismo informativo, probabilidade de exclusão e uma matriz de distância genética Euc1ideana. Considerando a média das distâncias Euclideanas, calculadas individualmente para cada marcador, a maior distância genética foi observada entre as raças Angus e Nelore (0,62) e as menores entre Caracu e as demais raças taurinas adaptadas (0,41 e 0,35 para Bonsmara e Senepol, respectivamente). Entre as taurinas adaptadas, a Bonsmara foi a que apresentou a menor distância em relação ao Angus (0,50) e a maior em relação ao Nelore (0,59). A raça Caracu apresentou distância intermediária para Angus (0,53) e Nelore (0,55). As raças Bonsmara e Caracu apresentaram distância genética, em média, 8,3% maior que a raça Senepol para matrizes Angus X Nelore, proporcionando uma expectativa de maior heterose quando cruzadas com estas matrizes

Wage Effects of Non-wage Labour Costs

We study wage effects of two important elements of non-wage labour costs: firing costs and payroll taxes. We exploit a reform that introduced substantial reduction in these two provisions for unemployed workers aged less than 30 and over 45 years who got a permanent job. A matching model with heterogeneous workers predicts positive wage effects of reducing firing costs but ambiguous wage effects of reducing payroll taxes, for both new entrant and incumbent workers. Difference-in-differences estimates and simulation of the model show positive wage effects for both new entrant and incumbent workers. The reduction in firing costs accounts for up to half of the overall wage increase for new entrants but only 10% for incumbents

Childcare restrictions and gender gap in labor outcomes

Persistent gender gaps exist in labor market outcomes. This study contributes to the literature by examining the gender gap effects of childcare restrictions. Specifically, not using professional childcare services due to issues like access, quality, or costs. Using a specialized module from the 2018 Spanish Labor Force Survey, we identify substantial gender gaps in labor force, employment, full-time employment and hours worked among parents facing childcare constraints. In contrast, parents without such restrictions experience much lower gender gaps. Working time flexibility helps to alleviate the gender gap in hours worked. Additionally, we explore the long-run consequences of extended work interruptions for childcare, revealing a significant decline in women's labor supply, employment rates and full-time share, particularly for career breaks lasting 5 years or more

Mechanisms of goethite dissolution in the presence of desferrioxamine B and Suwannee River fulvic acid at pH 6.5

Siderophores are Fe3+ specific low MW chelating ligands secreted by microorganisms in response to Fe stress. Low MW organic acids such as oxalate have been shown to enhance siderophore mediated dissolution of Fe3+ oxides. However, the effect of fulvic acid presence on siderophore function remains unknown. We used batch dissolution experiments to investigate Fe release from goethite in the goethite-fulvic acid desferrioxamine B (goethite-SRFA-DFOB) ternary system. Experiments were conducted at pH 6.5 while varying reagent addition sequence. FTIR and UV-Vis spectroscopy were employed to characterise the Fe-DFOB, Fe-SRFA and DFOB–SRFA complexes. Iron released from goethite in the presence of SRFA alone was below detection limit. In the presence of both SRFA and DFOB, dissolved Fe increased with reaction time, presence of the DFOB-SRFA complex, and where SRFA was introduced prior to DFOB. FTIR data show that in the ternary system, Fe3+ is complexed primarily to oxygen of the DFOB hydroxamate group, whilst the carboxylate C=O of SRFA forms an electrostatic association with the terminal NH3+ of DFOB. We propose that SRFA sorbed to goethite lowers the net positive charge of the oxide surface, thus facilitating adsorption of cationic DFOB and subsequent Fe3+ chelation and release. Furthermore, the sorbed SRFA weakens Fe-O bonds at the goethite surface, increasing the population of kinetically labile Fe. This work demonstrates the positive, though indirect role of SRFA in increasing the bioavailability of Fe3+

Labor disruption costs and real wages cyclicality

In this paper, we propose a matching and search model with adjustment costs in the form of labor disruption charges that can generate counter-cyclical real wages. Empirically, we use a measure of wage cyclicality based on the generalized impulse response function of real wages to a shock in a cycle measure. We provide evidence that wages in the United States are counter-cyclical during the first few quarters. The calibration and simulated results of the model match remarkably well the counter-cyclicality obtained from our empirical model
