Studies that evaluate the effects of technology shocks often employ structural VARs identified with long‐run restrictions. In the presence of a mismatch between the lag structures of the true data‐generating process and the adopted VAR, estimates based on long‐run restrictions can be biased. This paper offers a method that can reduce this bias substantially. Using artificial data, I assess the performance of the proposed method and find that it can outperform a range of alternative procedures. Applying the procedure to the US data, I find that per‐capita hours exhibit a positive hump‐shaped response profile in response to a technology shock.
