Traditionally identified monetary shocks in a structural vector autoregression (SVAR) model typically result in long-lasting effects on output and total factor productivity (TFP). In this paper, I argue that the typical monetary shock has been confounded with the news shock about future technology. I propose and implement a novel SVAR approach that effectively “cleans” the technology component from the traditional Cholesky monetary shock. With the new identification, I find that a monetary shock exerts smaller and less persistent effects on output and the level of measured TFP than a traditionally identified monetary shock. Finally, I show that the SVAR impulse responses can be replicated by augmenting the standard New Keynesian model with a time-varying inflation target and a non-Ricardian fiscal policy regime.

Evaluations of generic advertising programs by commodity check-off programs involve analyses of counterfactual scenarios in which advertising and promotion expenditures are set to zero over the program's history. In actual practice, the counterfactual is rarely realized. We present a case in which such a natural experiment occurred when generic advertising and promotion expenditures for U.S. orange juice were cut nearly to zero. Using structural econometric and autoregression models, we estimate losses in consumption and sales revenue and examine the time required for the market for orange juice to recover from the check-off's strategy of going nearly dark.

This paper considers a nonborrowed-monetary-base VAR and a targets and instrument framework favored by the monetarists to resolve the puzzles thrown up by monetary VAR studies. The results show that nonborrowed-monetary-base shocks produce responses consistent with a priori expectations about the effects of monetary policy on interest rates, prices, and output.
