We investigate the dynamics of return and liquidity (co) jumps for three most traded emerging market currencies vis-à-vis US dollar.

We decompose bid and ask quote log returns into three linear latent components: a common factor reflecting the informative efficient return and two noisy components capturing market side specific frictions, like liquidity-induced quote revisions. The latent return components are assumed to follow a conditionally heteroscedastic VAR(1) model where the conditional means and variances of the indiv...
