Abstract: The emergence of digital gig economy has changed the social relationships formed in the production. It represents a progress of technology, which makes labor contract less important and results in a decrease in wage stickiness. Such structural changes may weaken the effectiveness of monetary policy. This paper discusses the effect of digital gig economy on monetary policy effect by establishing a TANK-DSGE model which includes both conventional labor and digital gig industry, from the perspective of wage stickiness. To conclude, the rise of digital gig economy will reduce the positive effect of monetary policy on output and employment, in both quantity-based policy and price-based policy. It will boost the volatility in wage and price inflation caused by policy shock, and social welfare will decrease consequently. This research suggests that improve the statistical ability of the digital economy and standardizing the labor relation of digital gigs, to mitigate the negative effects above. And the central bank needs to manage well inflation expectations when executing monetary policy.
