The current account in developed countries is highly persistent and volatile in comparison to output growth. The standard intertemporal current account model with rational expectations (RE) fails to account for the observed current account dynamics together with persistent changes in...

Previous studies argue that, based on the New Keynesian framework, a fiscal stimulus financed by money creation has a strong positive effect on output under a reasonable degree of nominal price rigidities. This paper investigates the effects of implementation lag in the moneyfinanced fiscal...

Implementation lags are one of policymakers' concerns about fiscal policies, as these may reduce their efficacy. Using a standard New Keynesian model with an effective lower bound on the nominal interest rate, we compare the impacts of fiscal stimulus on output across various lengths of...

The search for new ideas by profit-seeking firms and knowledge spillovers are well-known and fundamental sources of modern economic growth. This paper examines the implications of idea production and knowledge capital for monetary business cycles. We construct a sticky-wage model where workers...

Previous studies have argued that output growth in advanced economies declined during the Great Recession and remained low afterward. This paper proposes a model to explain this slowdown in output growth. We incorporate wealth preferences and downward nominal wage rigidity into a standard...

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...

Recent studies on fiscal policy use cross-sectional data and estimate local fiscal multipliers along with spillovers. This paper estimates local fiscal multipliers with spillovers using Japanese prefectural data comparable with the national accounts. We estimate the local fiscal multiplier on...
