Do investment-specific technological changes matter for business fluctuations? Evidence from Japan

The observed decline in the relative price of investment goods to consumption goods in Japan suggests the existence of investment-specific technological (IST) changes. We examine whether IST changes are a major source of business fluctuations in Japan, by estimating a dynamic stochastic general equilibrium model with Bayesian methods. We show that IST changes are less important than neutral technological changes in explaining output fluctuations. We also demonstrate that investment fluctuations are mainly driven by shocks to investment adjustment costs. Such shocks represent variations of costs involved in changing investment spending, such as financial intermediation costs. We then find that the estimated series of the investment adjustment cost shock correlates strongly with the diffusion index of firms' financial position in the Tankan (Short-term Economic Survey of Enterprises in Japan). We thus argue that the large decline in investment growth in the early 1990s is due to an increase in investment adjustment costs stemming from firms' tight financial constraint after the collapse of Japan's asset price bubble

Identifying News Shocks with Forecast Data

Recent studies attempt to quantify the empirical importance of news shocks (ie., anticipated future schocks) in business cycle fluctuations. This paper identifies news schocks in a dynamic stochastic general equilibrium model estimated with not only actual data but also forecast data. The estimation results show new empirical evidence that antecipated future technology shocks are the most important driving force of U.S. business cycles. The use of the forecast data makes the anticipated shocks play a much more important role in fitting model-implied expectations to this data, since such shocks have persistent effects on the expectaions and thereby help to replicate the observed persistence of the forecasts.

Determinacy under inflation targeting interest rate policy in a sticky price model with investment (and labor bargaining)

In a sticky price model with investment spending, recent research shows that inflation-forecast targeting interest rate policy makes determinacy of equilibrium essentially impossible. We examine a necessary and sufficient condition for determinacy under interest rate policy that responds to a weighted average of an inflation forecast and current inflation. This condition demonstrates that the average-inflation targeting policy ensures determinacy as long as both the response to average inflation and the relative weight of current inflation are large enough. We also find that interest rate policy which responds solely to past inflation guarantees determinacy when its response satisfies the Taylor principle and is not large. These results still hold even when wages and hours worked are determined by Nash bargaining.

Labor market search and interest rate policy

We investigate implications of search and matching frictions in the labor market for in ation targeting interest rate policy in terms of equilibrium stability. When the interest rate is set in response to past or present in ation, determinacy of equilibrium is ensured similarly to comparable previous studies with frictionless labor markets. In stark contrast to these studies, indeterminacy is very likely if the interest rate is adjusted in response solely to expected future in ation. This is due to a vacancy channel of monetary policy that stems from the labor market frictions and renders in ation expectations self-ful lling. The indeterminacy can be overcome once the interest rate is adjusted in response also to output or the unemployment rate or if the policy contains interest rate smoothing. When E-stability is adopted as an equilibrium selection criterion, a unique E-stable fundamental rational expectations equilibrium is generated under active, but not too strong, policy responses only to expected future in ation. This suggests that the problem is not critical from the perspective of learnability of the fundamental equilibrium.

Inflation dynamics and labor market specifications: a Bayesian DSGE approach for Japan's economy

Which labor market specification is better able to describe inflation dynamics, a widely-used sticky wage model or a recently-investigated labor market search model? Using a Bayesian likelihood approach, we estimate these two models with Japan’s data. This paper shows that the labor market search model is superior to the sticky wage model in terms of both marginal likelihood and out-of-sample forecast performance, particularly regarding inflation. The labor market search model is better able to replicate the cross-correlation among inflation, real wages, and output in the data. Moreover, in this model, real marginal cost is determined by both hiring cost and unit labor cost that varies with employment fluctuations, which gives rise to a high contemporaneous correlation between inflation and real marginal cost as represented in the New Keynesian Phillips curve.Inflation dynamics; Marginal cost; Labor market search; Extensive margin; Bayesian estimation
