This paper demonstrates that observable trade cost measures in logs are not linearly related
to the overall log trade costs nor to the conditional mean of log bilateral trade flows. This is …

The 'paradox of progress' is an empirical regularity that associates more education with
larger income inequality. Two driving and competing factors behind this phenomenon are …

This paper extends the Oaxaca-Blinder decomposition method to the quantile regression
random-coefficients framework. Mean-based decompositions are obtained as the integration …

An increase in globalization and financial integration has induced countries to depend on
each other to survive. This has facilitated trade and investments among economies across …

This paper uses quantile regression techniques to investigate the temporal dependence
patterns of major exchange rates around the globe. Specifically, we estimate quantile …

This paper proposes a new econometric model for asymmetric price transmissions. We
estimate long-run equilibrium equations between upstream and downstream prices and use …

We provide a comprehensive view on volatility dynamics in precious metals and crude oil
markets. Using high-frequency futures data, we construct realized volatilities and estimate …

We evaluate two density estimators based on the quantile variance and the quantile-mean
covariance estimated by bootstrap. We review previous developments on density estimation …

The 'paradox of progess' is an empirical regularity that associates more education with
larger income inequality. Two driving and competing factors behind this phenomenon are …

Evaluamos dos estimadores de densidades basados en la varianza y la covarianza entre
media y varianza estimados por bootstrap. Revisamos otros desarrollos de estimadores de …
