R&D investment spending exhibits a delayed and hump-shaped response to shocks. We show in a simple partial equilibrium model that rapidly adjusting R&D investment is costly if the probability of converting new hires into productive R&D workers ("onboarding") is decreasing in the number of new...

We present a sticky-wage model with two types of labors: while worker's labor contributes to current production, researcherís work helps develop new ideas to add to firm's knowledge capital that enhances its productivity for many periods. The long-lived effect of knowledge capital on...

We develop a multisector model in which capital and labor are free to move across firms within each sector, but cannot move across sectors. To isolate the role of sectoral specificity, we compare our model with otherwise identical multisector economies with either economy-wide or firm-specific...

According to the Taylor principle a central bank should adjust the nominal interest rate by more than one-for-one in response to changes in current inflation. Most of the existing literature supports the view that by following this simple recommendation a central bank can avoid being a source of...

One of the most significant characteristics of optimizing models is that the behavioral equations involved are typically forward looking, i.e., agents are concerned about the future rather than the past. This creates difficulties when modelling some of the business-cycle patterns widely observed...

The propagation mechanism of monetary shocks in an otherwise standard sticky-price model is examined, modified to incorporate factor hoarding in the form of variable capital utilisation rates and labour effort. In contrast to previous studies, it is found that real effects of monetary shocks can...
