Due to its impact on nominal firm profits, price rigidity amplifies the response of entry and exit to supply shocks. When those supply shocks are negative, such as those following supply chain disruptions, this “entry-exit multiplier” substantially magnifies the associated welfare losses—especially when wages are also rigid. This is in stark contrast to the benchmark New Keynesian model (NK), which predicts a positive output gap in response to that same shock under the same monetary policy. Endogenous entry-exit thus radically changes the consequences of nominal rigidities.

We study the transmission of monetary policy shocks using daily consumption, corporate sales and employment series. We find that the economy responds at both short and long lags that are variable in economically significant ways. Consumption reacts in one week, reaches a local trough in one quarter, recovers, and declines again after three quarters. Sales follow a similar pattern, but the initial drop, while delayed (one month), is deeper. In contrast, employment falls monotonically for five quarters albeit with a smaller impact reaction.

In this paper, I investigate how the Net-Zero transition affects the transmission of monetary policy. I first document an upward trend in environmental performance among US publicly listed companies over the last decade. Second, I evaluate the implications of firms becoming ‘greener’ for the transmission of monetary policy on asset prices, credit risk and firm-level investment. In response to a shock to monetary policy, ‘green’ firms (with high environmental scores) are significantly less impacted than their ‘brown’ counterparts (with lower environmental scores).
