This work analyses the decision-making process underlying choice behaviour. First, neural and gaze activity were recorded experimentally from different subjects performing a choice task in a Web Interface. Second, choice models and ensembles were fitted using rational, emotional, and attentional features. The model's predictions were evaluated in terms of their accuracy and rankings were made for each user.The results show that (a) the attentional models are the best in terms of its average performance across all users, (b) each subject shows a different best model, and (c) ensembles may perform better than single choice models but an optimal building method has to be found.
During Substitution Industrialization (1930-1975), wages rose, and unemployment and poverty were low. During the “neoliberal process” (1976-2002) the liberalization of the goods and financial markets resulted in the regression of the productive structure, high unemployment and the decline of real wages. Finally, since the collapse of 2002, Argentina has had enormous success in terms of unemployment, with limited achievements in wages or poverty. This paper tries to answer why Argentina faces difficulties to return to past labor market figures highlighting the process of capital differentiation and the new international division of labor.
El artículo se propone estudiar la evolución del mercado laboral argentino durante las últimas tres décadas a la luz de un abordaje que toma en consideración la vigencia en cada momento del tiempo, con los distintos modelos de acumulación, del determinante estructural del ciclo económico nacional: la relación entre el rezago de productividad internacional y su disponibilidad de fuentes de compensación. Para ello, se analiza la dinámica de diferentes variables laborales relevantes (empleo, salario, evolución del sector informal urbano y calidad del vínculo laboral) en etapas identificadas según la dinámica económica general: 1991-2002, 2003-2011 y 2012-2021. La principal conclusión es que sólo en instancias de un flujo particularmente elevado de renta de la tierra (2008-2011) se logró una mejora genuina en las condiciones de empleo y de vida de la población argentina, la cual no logró revertir su pronunciado deterioro ocurrido desde mediados de la década de los setenta. Dicho deterioro se realizó a partir de una creciente diferenciación en las condiciones de reproducción de la fuerza de trabajo, lo cual tiene su correlato en la marcada fragmentación que caracteriza a la sociedad argentina actual vis-à-vis aquella de comienzos de la década de los setenta, que se destacaba en el panorama regional.
