This note studies exchange rate pass-through to the prices of domestically produced goods, exploring the firm-level pricing survey conducted by the Bank of Korea. The data reveal the imported inputs channel of, as well as nonlinear and asymmetric, exchange rate-pass-through.

This paper investigates nonlinear effects of government debt on private consumption. The estimated consumption function shows smooth regime switching depending on the debt-to-GDP ratio, and a higher level of government debt crowds out private consumption to a greater extent.

Linearity testing against smooth transition autoregressive (STAR) models when deterministic trends are potentially present in the data is considered in this work. Our findings show, in contrast to results recently reported in Zhang (2012), that linearity tests against STAR models lead to useful...

Pesaran and Yamagata (Pesaran, M.H., Yamagata, T., Testing slope homogeneity in large panels, Journal of Econometrics 142, 50–93, 2008) propose a test for slope homogeneity in large panels, which has become very popular in the literature. However, the test cannot deal with the practically...

This paper analyzes the maximum likelihood estimation for vector autoregressions with stochastic volatility. The stochastic volatility is modeled following Uhlig (1997). The asymptotic distribution of the maximum likelihood estimate is discussed under mild regularity conditions. The maximum...

A particular robust regression estimator has gained popularity among applied econometricians. We show that this estimator is inconsistent for the parameters of the conditional mean when the errors are skewed and heteroskedastic, and conclude that therefore its use cannot be generally recommended.
