Due to a sharp decline in the fertility rate and a rapid increase in longevity, Japan's population aging is the furthest advanced in the world. In this study we explore the macroeconomic impact of population aging using a full-fledged overlapping generations model. Our model replicates well the...

Between 1960 and 1990 Japanese labor productivity rose from 27 percent of the U.S. to 87 percent. These productivity gains are associated with large variations in Japanese TFP. We find that movements in Japanese TFP are associated with prior movements in U.S. R&D expenditures. Model simulations...

After empirically showing imperfect financial integration among the euro countries, i.e., bank loan market heterogeneities in stickinesses of loan interest rates and markups from policy interest rate to loan rates, we build a New Keynesian model where such elements of imperfect financial...

Despite the theoretical prediction based on sticky-price models, it is empirically suggested that the tie between the frequencies of price adjustment across goods and the relative price responses of goods (price index of specific goods over non-durable aggregate price index) to a monetary policy...

The co-movement of output across the sector producing non- durables (that is, non-durable goods and services) and the sector producing durables is well-established in the monetary business-cycle literature. However, standard sticky-price models that incorporate sectoral heterogeneity in price...

Recent empirical studies reveal that the oil price-output relationship is weakening in the US. Oil price-output correlation is less negative, and output reduction in response to oil price rise is more moderate after mid 1980s. In contrast to the conventional view that there have been changes in...

Japan is facing severe fiscal challenges. The aging of the population is projected to raise total pension and health expenditures. There is already a huge debt to output ratio, which is the highest among the advanced economies. In this paper we ask, gIf the consumption tax rate is raised to 15...
