The Distribution of Wealth and the Marginal Propensity to Consume

We present a macroeconomic model calibrated to match both microeconomic and macroeconomic evidence on household income dynamics. When the model is modified in a way that permits it to match empirical measures of wealth inequality in the U.S., we show that its predictions (unlike those of competing models) are consistent with the substantial body of microeconomic evidence which suggests that the annual marginal propensity to consume (MPC) is much larger than the 0.02_0.04 range implied by commonly-used macroeconomic models. Our model also (plausibly) predicts that the aggregate MPC can differ greatly depending on how the shock is distributed across categories of households (e.g., low-wealth versus high-wealth households).

Assessing the Risks to the Japanese Government Bond (JGB) Market

Despite the rise in public debt, Japanese Government Bond (JGB) yields have remained low and stable, supported by steady inflows from the household and corporate sectors, high domestic ownership of JGBs, and safe-haven flows from heightened sovereign risks in Europe. Over time, however, the markets capacity to absorb new debt will likely shrink as population ages and risk appetite recovers. In the short term, a decline in fund supply from the corporate sector, where financial surpluses are abnormally high, and spillovers from global financial distress could push up JGB yields. Fiscal reforms to reduce public debt more quickly and lengthen the maturity of government bonds will help limit these risks.

Does the Business Environment Affect Corporate Investment in India

Since the global financial crisis, corporate investment has been weak in India. Sluggish corporate investment would not only moderate growth from the demand side but also constrain growth from the supply side over time. Against this background, this paper analyzes the reasons for the slowdown and discusses how India can boost corporate investment, using both macro and firm-level micro data. Analysis of macro data indicates that macroeconomic factors can largely explain corporate investment but that they do not appear to account fully for recent weak performance, suggesting a key role of the business environment in reviving corporate investment. Analysis of micro panel data suggests that improving the business environment by reducing costs of doing business, improving financial access, and developing infrastructure, could stimulate corporate investment.

'Lost Decade'? In Translation: What Japan's Crisis Could Portend About Recovery from the Great Recession

Is the recovery from the global financial crisis now secured? A strikingly similar crisis that stalled Japans growth miracle two decades ago could provide some clues. This paper explores the parallels and draws potential implications for the current global outlook and policies. Japans experiences suggest four broad lessons. First, green shoots do not guarantee a recovery, implying a need to be cautious about the outlook. Second, financial fragilities can leave an economy vulnerable to adverse shocks and should be resolved for a durable recovery. Third, well-calibrated macroeconomic stimulus can facilitate this adjustment, but carries increasing costs. And fourth, while judging the best time to exit from policy support is difficult, clear medium-term plans may help.

Intergenerational Implications of Fiscal Consolidation in Japan

In Japan, intergenerational inequality in lifetime resources is substantial, with a heavier fiscal burden on the young than the old. Moreover, given the need for fiscal consolidation, the inequality is even worse than existing policy would suggest. However, this does not mean that fiscal consolidation would make the young worse off. Lack of fiscal consolidation would eventually increase interest rates, which would reduce output and hit young generations harder. Simulations using an overlapping generations model indicate that, from the perspective of intergenerational fairness, it would be desirable to include both social security spending reforms and revenue measures in a fiscal consolidation package. The simulations also show that delaying fiscal consolidation could be costly and worsen intergenerational resource inequality.

Buffer-stock saving in a Krusell–Smith world

We modify the widely-used Krusell and Smith (1998) model (KS) to accommodate an income process with permanent and transitory components. Appropriately calibrated permanent shocks help explain a substantial part of the empirical wealth heterogeneity unexplained in the baseline KS model.

Pension Reforms in Japan

This paper analyzes various reform options for Japan’s public pension in light of large fiscal consolidation needs of the country. The most attractive option is to increase the pension eligibility age in line with high and rising life expectancy. This would have a positive effect on long-run economic growth and would be relatively fair in sharing the burden of fiscal adjustment between younger and older generations. Other attractive options include better targeting by “clawing back” a small portion of pension benefits from wealthy retirees, reducing preferential tax treatment of pension benefit incomes, and collecting contributions from dependent spouses of employees, who are currently eligible for pension benefits even though they make no contributions. These options, if implemented concurrently, could reduce the government annual subsidy and the government deficit by up to 1¼ percent of GDP by 2020.
