An Alternative to even swaps for modeling decision in a multi attribute problem. The case of labor formality

El presente trabajo analiza dos alternativas para resolver problemas de múltiples criterios a la hora de tomar decisiones.Son analizados los modelos de “EVEN SWAPS” y “CHOICE BASED CONJOINT (CBC), utilizando una elección entre trabajos hipotéticos como marco de la toma de decisiones.Se muestra que no solo se puede utilizar el análisis de “CHOICE BASED CONJOINT” (CBC) para evaluar intercambios asociados, sino que el mismo también se puede utilizar para predecir las elecciones de las personas incluso cuando no son conscientes de los cambios entre criterios.Finalmente, se utilizó una encuesta experimental realizada a medida para mostrar en práctica el método CBC, permitiendo obtener importantes conclusiones sobre la voluntad de las personas para pagar varios aspectos de las formalidades laborales.This paper discusses two different alternatives to deal with the problem of multiple objectives in decision making. Even Swaps and Choice Based Conjoint are analyzed using an election between hypothetical jobs as a frame of decision. We show that not only Choice Based Conjoint Analysis can be used to value the different tradeoffs associated, but it can also be used to predict people choices even when they are not aware of the trades involved between objectives. Finally a tailored pilot survey is used to show the Choice Based Method in practice, allowing us to obtain important conclusions regarding people willingness to pay for several Labor Formality aspects

Biased Perceptions of Income Distribution and Preferences for Redistribution: Evidence from a Survey Experiment

Individual perceptions of income distribution play a vital role in political economy and public finance models, yet there is little evidence regarding their origins or accuracy. This study examines how individuals form these perceptions and posits that systematic biases arise from the extrapolation of information extracted from reference groups. A tailored household survey provides original evidence on the significant biases in individuals’ evaluations of their own relative position in the distribution. Furthermore, the data supports the hypothesis that the selection process into the reference groups is the source of those biases. Finally, this study also assesses the practical relevance of these biases by examining their impact on attitudes towards redistributive policies. An experimental design incorporated into the survey provides consistent information on the own ranking within the income distribution to a randomly selected group of respondents. Confronting agents’ biased perceptions with this information has a significant effect on their stated preferences for redistribution. Those who had overestimated their relative position and thought of themselves relatively richer than they were demand higher levels of redistribution when informed of their true ranking. This relationship between biased perceptions and political attitudes provides an alternative explanation for the relatively low degree of redistribution observed in modern democracies.preferences for redistribution, limited information, perceptions of income distribution, field experiment

Quality of Life in Buenos Aires Neighborhoods: Hedonic Price Regressions and the Life Satisfaction Approach

This paper studies quality of life in urban neighborhoods in the Buenos Aires Metropolitan Area. First, hedonic price regressions for residential prices are augmented with neighborhood characteristics, based on a real estate database with indicators on each property’s distance to public facilities and amenities, and on a smaller survey with greater detail. Second, following recent developments in the field of happiness research, the document assesses the importance of different neighborhood characteristics on quality of life by interacting objective and subjective indicators. Indices of quality of life related to local amenities are derived for the different neighborhoods for both the hedonic regression and life satisfaction approaches. The results indicate a strong but not perfect correlation between real estate prices, income levels and neighborhood characteristics, suggesting scope for welfare-improving policy interventions.

Biased perceptions of income distribution and preferences for redistribution: Evidence from a survey experiment

Individual perceptions of income distribution play a vital role in political economy and public finance models, yet there is little evidence regarding their origins or accuracy. This study examines how individuals form these perceptions and explores their potential impact on preferences for redistribution. A tailored household survey provides original evidence on systematic biases in individuals' evaluations of their own relative position in the income distribution. The study discusses one of the mechanisms that may generate such biases, based on the extrapolation of information from endogenous reference groups, and presents some suggestive evidence that this mechanism has significant explanatory power. The impact of these biased perceptions on attitudes toward redistributive policies is studied by means of an experimental design that was incorporated into the survey, which provided consistent information on the own-ranking within the income distribution to a randomly selected group of respondents. The evidence suggests that those who had overestimated their relative position and thought that they were relatively richer than they were tend to demand higher levels of redistribution when informed of their true ranking.Fil: Cruces, Guillermo Antonio.

Determination of Protein–Ligand Binding Constants of a Cooperatively Regulated Tetrameric Enzyme Using Electrospray Mass Spectrometry

This study highlights the benefits of nano electrospray ionization mass spectrometry (nanoESI-MS) as a fast and label-free method not only for determination of dissociation constants (<i>K</i>_D) of a cooperatively regulated enzyme but also to better understand the mechanism of enzymatic cooperativity of multimeric proteins. We present an approach to investigate the allosteric mechanism in the binding of inhibitors to the homotetrameric enzyme fructose 1,6-bisphosphatase (FBPase), a potential therapeutic target for glucose control in type 2 diabetes. A series of inhibitors binding at an allosteric site of FBPase were investigated to determine their <i>K</i>_Ds by nanoESI-MS. The <i>K</i>_Ds determined by ESI-MS correlate very well with IC₅₀ values in solution. The Hill coefficients derived from nanoESI-MS suggest positive cooperativity. From single-point measurements we could obtain information on relative potency, stoichiometry, conformational changes, and mechanism of cooperativity. A new X-ray crystal structure of FBPase tetramer binding ligand <b>3</b> in a 4:4 stoichiometry is also reported. NanoESI-MS-based results match the current understanding of the investigated system and are in agreement with the X-ray structural data, but provide additional mechanistic insight on the ligand binding, due to the better dynamic resolution. This method offers a powerful approach for studying other proteins with allosteric binding sites, as well
