Optimality of the Friedman rule under ambiguity
Eisei Ohtaki

This article reexamines optimality of the Friedman rule in an economy, wherein (i) spatial separation and limited communication create a transactions role for money (ii) banks arise to provide liquidity, and (iii) agents are nonsmooth ambiguity aversion. It is shown that the structure of the set of “second-best” monetary policies crucially depends on the relation between the set of beliefs and the marginal productivity of capital. Especially, in order for the Friedman rule to be suboptimal, it is necessary for the maximum of subjective probabilities of realizing liquidity events to be sufficiently small.

Transmission Channels and Welfare Implications of Unconventional Monetary Easing Policy in Japan
Hiroshi Ugai

This paper examines the effects of the Quantitative and Qualitative Monetary Easing Policy (QQE <2013-current>) of the Bank of Japan (BOJ) by transmission channels in comparison with those of the Comprehensive Monetary Easing Policy (CE) and the subsequent monetary easing policies (2010-2012), based on the event study using financial market data. As for the QQE under normal market conditions, depreciation of foreign exchange rate in the context of portfolio balance channel functions quite strongly, while as for the CE, signaling channel through the commitment and credit easing channel at the dysfunctional markets work. The direct inflation expectation channel is weak for both QQE and CE, although the QQE has adopted various ways to exert a direct and strong influence on inflation expectation. It can be conjectured that the gradual rise in inflation expectation comes mainly from other channels like the depreciation of the yen. The most crucial characteristic of the QQE is to maximize the potential effects of easing policy by explicitly doubling and later tripling the purchased amount of JGBs and then the monetary base proportionally. The amount of JGB purchases by the BOJ surpasses the issuance amount of JGBs, thereby reducing the outstanding amount of JGBs in the markets. Shortage of safety assets would increase the convenience yield, which itself would reduce the economic welfare and not permeate the yields of other risky assets theoretically. This paper then examines the impact of reduction in JGBs on yield spreads between corporate bonds and JGBs based on money-in-utility type model applied to JGBs, and finds that at least severe scarcity situations of JGBs as safe assets are avoided, since the size of Japan’s public debt outstanding is the largest in the world. Even so, the event study shows no clear evidence that the decline in the yield of long-maturity JGBs induced by the QQE permeates the yields of corporate bonds. Recently demands for JGBs have been increasing from both domestic and foreign investors as collaterals after the Global Financial Crisis and from financial institutions that have to correspond to strengthened global liquidity regulation, while the Government of Japan is planning to consolidate the public debts. These recent changes as well as market expectation for future path of JGB amounts should also be taken account of to examine the scarcity of safe assets in case of further massive purchases of JGBs.

Conservatism and Liquidity Traps
Taisuke Nakata and Sebastian Schmidt

In an economy with an occasionally binding zero lower bound (ZLB) constraint, the anticipation of future ZLB episodes creates a trade-off for discretionary central banks between inflation and output stabilization. As a consequence, inflation systematically falls below target even when the policy rate is above zero. Appointing Rogoff’s (1985) conservative central banker mitigates this deflationary bias away from the ZLB and enhances welfare by improving allocations both at and away from the ZLB.

Multiplier Impacts and Emission Reduction Effects of Joint Crediting Mechanism: Analysis with a Japanese and International Disaggregated Input-Output Table
Makoto Sugino, Minoru Morita, Kazuyuki Iwata and Toshi H. Arimura

The reduction of emissions from developing countries is essential in tackling climate change. The Clean Development Mechanism has been effective but criticized by various parties. In response, the Japanese government has proposed the Joint Crediting Mechanism (JCM). Using the 2010 Japanese domestic and the 2005 Asian international input-output tables, we disaggregate the automobile industry and other electrical devices and parts industry to capture hybrid vehicles and solar panels. Moreover, we add the wind turbine industry and the geothermal turbine industry. In evaluating the JCM, we find that the multiplier impacts of hybrid vehicles, wind turbines and air conditioners are high, whereas boilers and solar panels produce smaller effects. In contrast, the results for the employment effects show that the coke dry quenching plants and lighting equipment create more jobs. We also estimate the emission reduction from the JCM. Taking into account the lifetime of each product/technology and country-specific emission coefficients, we find that lighting equipment’s emission reductions are the greatest, whereas washing machines’ reductions are the least. Thus, it is important to choose the technologies/items suitable for the JCM by balancing their economic and reduction effects. The government must assess various technologies/items before determining the eligibility of each technology/item.

Fiscal Cost to Exit Quantitative Easing: The Case of Japan
Hiroshi Fujiki and Hajime Tomura

This paper simulates the cash flows and balance sheets of the Bank of Japan (BoJ) before and after exiting from Quantitative and Qualitative Monetary Easing (QQE) under various scenarios. The simulations show that the BoJ will record significant accounting losses after exiting QQE. These losses are fiscal costs for the consolidated Japanese government as they represent increased interest expenses to the public and will arise because the BoJ will acquire a large amount of Japanese government bonds at very low interest rates during QQE, whose interest payments will then be insufficient to cover interest expenses on excess reserves after exiting QQE. Moreover, any cumulative accounting losses will ensure the BoJ’s net asset position remains negative for a sustained period of time. We also find that the BoJ’s accounting losses will increase with the duration of QQE and the interest rate elasticity of banknote demand, and decrease if the BoJ conducts tapering following the ending of QQE. Finally, the effect of tapering will be significantly stronger if there is no safety channel for the long-term interest rate.

Poverty decomposition by regression: An application to Tanzania
Tomoki Fujii

We develop a poverty decomposition method that is based on a consumption regression model. Because this method uses an integral of the partial derivatives of a poverty measure with respect to time, the resulting poverty decomposition satisfies time-reversion consistency and sub-period additivity. Unlike the existing poverty decomposition methods, it allows us to ascribe the observed change in poverty to various covariates of interest collected at a disaggregate level. This method is applied to two datasets from Tanzania to assess, among others, the short- and long-term impacts of infrastructure and market access on poverty.

Electric Appliance Ownership and Usage: Application of Conditional Demand Analysis to Japanese Household Data
Shigeru Matsumoto

Although both appliance ownership and usage patterns determine residential electricity consumption, it is less known how households actually use their appliances. In this study, we conduct conditional demand analyses to break down total household electricity consumption into a set of demand functions for electricity usage, across 13 appliance categories. We then examine how the socioeconomic characteristics of the households explain their appliance usage. Analysis of micro-level data from the Nation Survey of Family and Expenditure in Japan reveals that the family and income structure of households affect appliance usage. Specifically, we find that the presence of teenagers increases both air conditioner and dishwasher use, labor income and nonlabor income affect microwave usage in different ways, air conditioner usage decreases as the wife。ッs income increases, and microwave usage decreases as the husband。ッs income increases. Furthermore, we find that households use more electricity with new personal computers than old ones; this implies that the replacement of old personal computers increases electricity consumption.

Effects of Parental Leave Policies on Female Career and Fertility Choices
Shintaro Yamaguchi

This paper constructs and estimates a dynamic discrete choice structural model of labor supply, occupational choice, and fertility in the presence of parental leave legislation. The estimated structural model is used for an ex ante evaluation of parental leave expansions that change the duration of job protection and/or the replacement rate of the cash benefit. Counterfactual simulation results indicate that a one-year job protection significantly increased maternal employment and earnings, but extending it from one to three years and offering cash benefits have little effect. Overall, parental leave policies have little effect on fertility. I also find that policy effects are stronger for younger cohorts who observe a policy change several years before childbearing, because they adjust their career paths accordingly as soon as the policy change.

Inter-industry labor reallocation and task distance
Ayako Kondo and Saori Naganuma

This paper investigates factors preventing inter-industry labor reallocation by estimating the determinants of inter-industry worker flow and earnings change after a job change. We find that the difference in required tasks is an important reason for earnings reduction after an inter-industry job change, and thus, workers may hesitate to move to industries requiring a different set of tasks for fear of losing the wage premium acquired by task-specific human capital. In addition, more workers switch to industries with which their previous industry had larger transactions, although it affects earnings changes only marginally. On the other hand, industry performance does not affect labor inflow or wage changes significantly for inter-industry job changes. Young men, less educated women, and those quitting previous jobs for family or health reasons are more likely to move to industries requiring a different set of tasks, and young individuals who lost their jobs involuntarily are less likely to do so. Individuals more likely to move are not necessarily those whose earnings loss associated with the move is small: earning losses associated with task distance are relatively small among younger and less educated workers and are uncorrelated with the reasons for quitting the previous job.
