In this paper, we consider a family of recently-proposed measurement invariance tests that are based on the scores of a fitted model. This family can be used to test for measurement invariance w.r.t. a continuous auxiliary variable, without pre-specification of subgroups. Moreover, the family...

Measurement invariance is a fundamental assumption in item response theory models, where the relationship between a latent construct (ability) and observed item responses is of interest. Violation of this assumption would render the scale misinterpreted or cause systematic bias against certain...

A poor liquidity level and a high liquidity risk significantly raise the required return for small-cap stocks. Euronext allows these firms to hire designated market makers (DMMs) who guarantee a minimum liquidity supply for a lump sum annual fee. In an event study based on 74 DMM stocks, we find...

This paper investigates the effect of robot adoption on employment adjustment in China. By using detailed Chinese firm-level data and addressing endogeneity, we find that using industrial robots increases employment within firms, especially when focusing on the employment of high-educated and...

This paper investigates the effect of robot adoption on employment adjustment at the firm level in China. Using an instrument that exploits the source of the firm-level variation in robot adoption, we find that using industrial robots increases employment within firms, especially when focusing...

This paper highlights a previously-unnoticed property of commonly-used discrete choice models, which is that they feature parallel demand curves. Specifically, we show that in random utility models, inverse aggregate demand curves shift in parallel with respect to variety if and only if the...
