Monetary policy regime switches and macroeconomic dynamic
This paper investigates how different monetary policy regime switching types impact macroeconomic dynamics. Policy switches that either affect the inflation target or the response to inflation deviations from target lead to different determinacy regions and different output, inflation, and interest rate distributions. With regime switching, the standard Taylor Principle breaks down in multiple ways; satisfying the Principle period-by-period is neither necessary nor sufficient for determinacy. Switching inflation targets primarily affects the economy's level, whereas switching inflation ...

How Have Changing Sectoral Trends Affected GDP Growth?
Trend GDP growth has slowed about 2.3 percentage points to 1.7% since 1950. Different economic sectors have contributed to this slowing to varying degrees depending on the distinct trends of technology and labor growth in each sector. The extent to which sectors influence overall growth depends on the degree of spillovers to other sectors, which amplifies the effect of sectoral changes. Three sectors with slowing growth and linkages to other sectors?construction, nondurable goods, and professional and business services?account for 60% of the decline in trend GDP growth.

Optimal monetary policy regime switches
Given regime switches in the economy?s growth rate, optimal monetary policy rules may respond by switching policy parameters. These optimized parameters differ across regimes and from the optimal choice under fixed regimes, particularly in the inflation target and interest rate inertia. Optimal switching rules produce welfare gains relative to constant rules, with switches in the implicit real interest rate used for policy and the degree of interest rate inertia producing the largest gains. However, gains from switching rules decrease if the monetary authority trades-off the probability of ...

Financial crises, unconventional monetary policy exit strategies, and agents' expectations
This paper considers a model with financial frictions and studies the role of expectations and unconventional monetary policy response to financial crises. During a financial crisis, the financial sector has reduced ability to provide credit to productive firms, and the central bank may help lessen the magnitude of the downturn by using unconventional monetary policy to inject liquidity into credit markets. The model allows parameters to change according to a Markov process, which gives agents in the economy expectation about the probability of the central bank intervening in response to a ...

The asymmetric effects of uncertainty.
Recovery from the recent financial crisis has been sluggish by historical standards, and employment growth has been similarly disappointing. Three periods of heightened economic uncertainty?the European sovereign debt crisis, the U.S. debt ceiling crisis, and, to a lesser extent, 2013's brief "taper tantrum"?may have contributed to this lackluster response. Foerster introduces a statistical model to analyze spikes in stock market volatility during these periods and thus quantify uncertainty's influence. He finds that uncertainty has asymmetric effects, with large increases in uncertainty ...

Sectoral vs. aggregate shocks : a structural factor analysis of industrial production
This paper uses factor analytic methods to decompose industrial production (IP) into components arising from aggregate shocks and idiosyncratic sector-specific shocks. An approximate factor model finds that nearly all (90%) of the variability of quarterly growth rates in IP are associated with common factors. Because common factors may reflect sectoral shocks that have propagated by way of input-output linkages, we then use a multisector growth model to adjust for the effects of these linkages. In particular, we show that neoclassical multisector models, of the type first introduced by Long ...

Perturbation methods for Markov-switching DSGE model
The macroeconomic environment often changes repeatedly over time, and often in a recurring manner. For example, the economy may switch between periods of high and low growth, or monetary policy may switch between periods of strong versus weak responses to inflation. An important question for economists is how to model the presence of these switches, and to capture how expectations about switches in the future may impact economic behavior. ; This paper develops a methodology for solving dynamic stochastic general equilibrium (DSGE) models in the presence of switching environments. The approach ...
