The main goal when fitting GARCH models to conditionally heteroscedastic time series is to estimate the underlying volatilities. It is well known that outliers affect the estimation of the GARCH parameters. However, little is known about their effects when estimating volatilities. In this paper,...

The objective of this paper is to analyze the finite sample performance of two variants of the likelihood ratio test for detecting a level shift in uncorrelated conditionally heteroscedastic time series. We show that the behavior of the likelihood ratio test is not appropriate in this context...

This paper analyzes the effects caused by outliers on the identification and estimation of GARCH models. We show that outliers can lead to detect spurious conditional heteroscedasticity and can also hide genuine ARCH effects. First, we derive the asymptotic biases caused by outliers on the...

This paper investigates the implications of major ¯nancial markets crises for the human capital accumulation decisions of households. We use data for Argentinean households over the period 1995-2002 to examine households' response to negative idiosyncratic income shocks in di®erent...

We estimate the return to education using a sample drawn from the National Longitudinal Survey of Youth 1979 (NLSY79). Rather than accounting for the endogeneity of schooling through the use of instrumental variables we employ a parametric version of the Klein and Vella (2006a) estimator. This...

Using a sample of mother-child pairs from the National Longitudinal Survey of Youth 1979 we explore the intergenerational transmission of a social norm regarding women¿s roles and examine its implications for the labor market behavior of females. We find that a mother¿s attitudes towards...

This paper investigates the degree of intergenerational transmission ofeducation for individuals from the National Longitudinal Survey of Youth1979. Rather than identifying the causal effect of parental education viainstrumental variables we exploit the feature of the transmissionmechanism...

This paper investigates the effect of disclosing information on the discriminatory behaviour against immigrants in the Spanish rental market. We conduct a field experiment where emails are sent showing interest on vacant rental apartments. Fictitious applicants whose names represent different...

This paper studies discrimination against immigrants in the consumer market in Spain. We send emails of fictitious buyers to a popular Spanish second hand market webpage similar to ebay. Sellers are approached randomly by buyers with Spanish native or foreign sounding names to signal their...

We conduct a field experiment to show that discrimination in the rental market represents a significant obstacle for the geographical assimilation process by immigrants. We employ the Internet platform to identify vacant rental apartments in different areas of the two largest Spanish cities,...
