The paper relates cumulative prospect theory to the moments of returns distributions, e.g. skewness and kurtosis … related to the skewness. However, the relation is negative when probability weighing is set aside. This shows that cumulative … prospect theory investors display a preference for skewness through the probability weighting function. Furthermore, the …

In this paper a test procedure is proposed for the skewness in autoregressive conditional volatility models. The size …

We exploit inequality restrictions on higher-order moments of the distribution of structural shocks to sharpen their identification. We show that these constraints can be treated as necessary conditions and used to shrink the set of admissible rotations. We illustrate the usefulness of this...

The techniques of exploratory data analysis include a resistant rule, based on a linear combination of quartiles, for identification of outliers. This paper shows that the substitution of the quartiles with the median leads to a better performance in the non-Gaussian case. The improvement occurs...

This paper provides a brief survey of the bootstrap and its use in econometrics. As an introduction, the paper gives a description of the basics of the method, with a special emphasis on boostrap testing. A fairly large amount of space is devoted to discuss why bootstrap tests provide...

The presence of seasonal fluctuations (regular behavior along the year related to weather or institutional factors) invalidates monthly (quarterly) comparisons. In turn, since inter-annual variations depend on the comparison basis being used, they could provide very little information to the...

This paper summarizes the background, type, logic, and working procedure of the statistical matching used in the Levy Institute Measure of Economic Well-Being (LIMEW) project to combine the various data sets used to produce the synthetic data set with which the LIMEW is constructed. The authors...

Propensity score based-estimators are commonly used to estimate causal effects in evaluation research. To reduce bias in observational studies researchers might be tempted to include many, perhaps correlated, covariates when estimating the propensity score model. Taking into account that the...

This paper assesses the quality of the statistical matching used in the LIMTIP estimates for Italy for 2008 and 2014. The match combines the 2008-9 and 2013-14 Italian Time Use Survey (IT-TUS) with the Italian data collected for the European Survey on Income and Living Conditions (IT-SILC) in...
