Tax changes are often announced before their implementation and are not permanent, but rather only temporary. Accordingly, R&D firms will optimally adjust their investment decisions to fit tax schedule changes. This study analyzes how changes in various tax rates relevant to corporate activities...

We develop a Keynesian cross analysis with a dynamic optimization setting that explains long-run stagnation caused by aggregate demand deficiency. We show that an increase in government purchases boosts GDP through a multiplier process, but the implication is quite different from the...

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...

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...

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...

In this paper, I find (1) that Japan showed massive and persistent current account surpluses from at least 1981 and until at least 2011, (2) that Professor Ronald McKinnon was correct, at least in the case of Japan, and that these large and persistent current account surpluses were due primarily...

It has been empirically observed that consumption responds positively to government spending shock, however, existing models with intertemporally-optimizing households do not easily reconcile this stylized fact. This paper aims to address this discrepancy between models and data, focusing on the...

We propose a microeconomic foundation of the multiplier effect and that of the consumption function using a dynamic optimization model that explains a shortage of aggregate demand and unemployment. We show that government purchases boost aggregate demand through a multiplier-like process but...

In a Diamond-type overlapping-generations setting public debt issuance places no burden on future generations including those who repay the debt if prices and wages are fixed and unemployment occurs in the periods in which public bonds are issued and repaid. Whether the collected fund is spent...

Unless free international lending/borrowing is allowed, domestic saving equals domestic investment and hence saving and investment taxes have the identical effect, as is the case in a closed-economy context. However, if it is allowed, households can accumulate foreign assets besides domestic...
