Fiscal sustainability in Japan

This paper investigates fiscal sustainability of Japan by providing a dynamic stochastic general equilibrium (DSGE) model that features the low interest rate of the government bond relative to the economic growth rate to mimic the actual data. We evaluate fiscal sustainability by investigating whether the expected path of the debt-to-GDP ratio stabilizes or increases without bound. The debt-to-GDP ratio depends crucially on the projected growth rate and the fiscal policy rule. If the government does not react to the current fiscal crisis, the debt-to-GDP ratio will increase without bound, and then the fiscal policy is not sustainable. If the fiscal rule uses Bohn’s (1998) idea that involves the response of the primary surplus to the debt, sustainability improves. This rule provides a useful and realistic reform plan in the short and long runs.     

Forecasting U.S. car sales and car registrations in Japan: Rationality, accuracy and herding

We analyze forecasts of car sales in the U.S. and forecasts of car registrations in Japan. We document a substantial heterogeneity of forecasts, and we show that, based on traditional criteria, forecasts are neither rational nor unbiased. We also report that forecasters anti-herd, that is, forecasters seem to intentionally scatter their forecasts around a consensus forecast. We further show that cross-sectional heterogeneity of forecasts with regard to anti-herding transmits onto cross-sectional heterogeneity of forecast accuracy. Specifically, we document that forecasters who herd provide more accurate forecasts than their colleagues who anti-herd.     

Cooperative fiscal policy at the zero lower bound

This paper investigates the use of fiscal policy in response to a large negative aggregate demand shock which may push the global economy into a liquidity trap. Fiscal policy may be an effective tool to respond to a liquidity trap, but its international spillover effects may operate quite differently from its domestic effects. We derive the optimal cooperative fiscal response to a global liquidity trap in a two country world economy. Surprisingly, we find that the optimal fiscal spending response for a partner country to a negative aggregate demand shock in a source country may be negative. If fiscal policy can be chosen under policy commitment, the optimal response involves current fiscal expansion combined with future fiscal contraction, after the liquidity trap has ended.     

Monetary policy rules for a developing country: Evidence from Pakistan

This paper estimates forward-looking monetary policy rules to examine the interest rate setting behavior of the State Bank of Pakistan. Considering the external constraints on monetary policy, core inflation and a country-specific measure of the output gap, we demonstrate that the State Bank of Pakistan reacts to changes in inflation, the output gap and the federal funds rate.     

Responding to the global financial crisis: Vietnamese exchange rate policy, 2008–2009

The paper presents an analysis of exchange rate policy in Vietnam during 2008–2009. In early 2008, the country faced a sudden reversal of capital flows as signs of developing domestic vulnerabilities became evident. The downward pressure on the dong then intensified with the onset of the global financial crisis in the fall. In these environments, the Vietnamese authorities responded with various exchange rate policy measures. The paper documents a shift in Vietnam's de facto exchange rate regime, from a basket peg to a simple US dollar peg, when the domestic vulnerabilities became compounded by the evolving global crisis. The authorities utilized additional measures to relieve pressure on the parallel exchange rate. An event study methodology finds little evidence of systematic effectiveness for these policy actions; any effectiveness was short-lived. A close examination of individual actions suggests that the impact of foreign exchange market intervention appeared more consistent than any other type of measure and most effective when combined with other measures.     

Japanese government debt and sustainability of fiscal policy

We construct quarterly series of the revenues, expenditures, and debt outstanding for Japan from 1980 to 2010, and analyze the sustainability of the fiscal policy. We pursue three approaches to examine the sustainability. First, we calculate the minimum tax rate that stabilizes the debt to GDP ratio given the future government expenditures. Using 2010 as the base year, we find that the government revenue to GDP ratio must rise permanently to 40–47% (from the current 33%) to stabilize the debt to GDP ratio. Second, we estimate the response of the primary surplus when the debt to GDP ratio increases. We allow the relationship to fluctuate between two “regimes” using a Markov switching model. In both regimes, the primary surplus to GDP ratio fails to respond positively to debt, which suggests the process is explosive. Finally, we estimate a fiscal policy function and a monetary policy function with Markov switching. We find that the fiscal policy is “active” (the tax revenues do not rise when the debt increases) and the monetary policy is “passive” (the interest rate does not react to the inflation rate sufficiently) in both regimes. These results suggest that the current fiscal situation for the Japanese government is not sustainable.     

Bayesian analysis of time-varying parameter vector autoregressive model for the Japanese economy and monetary policy

This paper analyzes the time-varying parameter vector autoregressive (TVP–VAR) model for the Japanese economy and monetary policy. The parameters are allowed to follow a random walk process and estimated using the Markov chain Monte Carlo method. The empirical result reveals the time-varying structure of the Japanese economy and monetary policy during the period from 1981 to 2008. The marginal likelihoods of the TVP–VAR model and other fixed parameter VAR models are estimated for model comparison. The estimated marginal likelihoods indicate that the TVP–VAR model best fits the Japanese economic data.     

The usefulness of earnings versus book value for predicting stock returns and cross corporate ownership in Japan

Using a sample of Japanese firms, this paper evaluates the usefulness of the two fundamental products of an accrual accounting system, namely accrual earnings and book value of equity for predicting stock returns. Our analysis shows that both earnings and book value for Japanese firms have the ability to provide for profitable trading strategies or improved portfolio decisions, and that relative to the trading strategy based on earnings or book value alone, the trading strategy based on a combination of both earnings and book value generates substantially higher returns for all cases. This suggests that book value (or earnings) captures certain aspects of equity values that are not captured by earnings (book value). Our multivariate regression results further indicate that the predictive ability of earnings is dominated by that of book value. Finally, it is found that the predictive ability of book value is sensitive to the degree of cross corporate ownership, while it is insensitive to the degree of real estate holding.     

Entrepreneurship and business culture in Japan and the U.S.

It seems to me likely that entrepreneurship will take a different path in Japan than it has in the U.S. Given the prominence of large organizations in key areas of Japan's economy and the emphasis its society places on lifetime employment relationships, many of the “startups” of the sort that transformed the American business are more likely to happen within existing firms rather than as new enterprises. Such development, called “intrapreneurship” in the U.S. requires new institutional structures and rewards. Such changes will not come easily, because they run against the grain of Japanese society and business culture, yet I believe that success will come to those who can execute such strategies.     

Political instability and inflation in Pakistan

This study investigates the effects of political instability on inflation in Pakistan. Applying the Generalized Method of Moments technique and using data from 1951 to 2007, we examine this link through two different models. The results of the ‘monetary’ model suggest that the effects of monetary determinants are rather marginal and that they depend upon the political environment of Pakistan. The ‘nonmonetary’ model's findings explicitly establish a positive association between political instability and inflation. This is further confirmed through analysis based on interactive dummies that reveal political instability significantly leading to high (above average) inflation.     

Monetary vs. fiscal policy: Some evidence from vector autoregression for India

This paper investigates the relative importance of monetary and fiscal policy for India. Unlike previous studies, a more general approach of multivariate vector autoregression has been employed. Analysis of the causality results based on the joint F-tests and the dynamic multipliers based on the variance decompositions and the impulse response functions unambiguously support the Keynesian stance on the importance of fiscal policy. There is very little evidence of exogeneity of money supply, undermining the validity of the monetarist proposition. On the contrary, Indian monetary policy appears to have accommodated changes in government expenditure, prices and output, lending support to the structuralist-Mundellian views.     

A new anatomy of the retirement process in Japan

In Japan, retirement is a gradual process that transpires over a particularly long period of time. Using large scale micro-level datasets from the Survey of Employment of the Elderly compiled by the Japanese government, we provide some stylized facts on the development of retirement behavior since the 1980s and explore factors affecting the individual retirement decision. First, we observed a general declining trend in the proportion of retired individuals aged 55–59 (especially females) while the proportion of retired individuals aged 65–69 (especially males) increased. Second, the survival analysis on actual retirement age shows that those who are more educated are more likely to retire earlier and those who experienced mandatory retirement are less likely. Third, the survival analysis on the expected retirement age shows that individuals who are satisfied with their job in terms of nonmonetary rewards are less likely to retire earlier.     

Health insurance reform and economic growth: Simulation analysis in Japan

This paper evaluates the drastic reforms of Japanese public health insurance initiated in 2006. We employ a computable general equilibrium framework to numerically examine the reforms for an aging Japan in the dynamic context of overlapping generations. Our simulation produced the following results: first, an increase in the co-payment rate, a prominent feature of the 2006 reform, would promote economic growth and welfare by encouraging private saving. Second, the ex-post moral hazard behavior following the increase in co-payment rates, however, reduces economic growth. Third, Japan's trend of increasing the future public health insurance benefits can mainly be explained by its aging population, and increasing the co-payment rate does little to reduce future payments of public health insurance benefits. Fourth, the effect on future economic burdens of reducing medical costs through efficiencies in public health insurance, emphasis on preventive medical care, or technological progress in the medical field is small. Finally, a policy of maintaining public health insurance at a fixed percentage of GDP will require reducing public health insurance benefits, perhaps up to 45% by 2050. Such a policy also reduces economic growth until approximately 2035. Our simulation indicates that the reform does not significantly reduce future public health insurance benefits, but it can enhance economic growth and welfare by encouraging private saving.     

Business cycle transmission and interdependence between Japan and Australia

This paper investigates business cycle transmission and interdependence between Australia and Japan over the period 1961.1–1994.4. Vector autoregression (VAR) and vector error correction (VEC) models were constructed utilizing GDP/GNPs, producer prices, interest rates and money supplies. The model is tested for cointegration. Two cointegrating vectors are found, and a vector error correction (VEC) model is estimated. The coefficients and the F-tests of the VEC are used to measure the effect of one economy upon the other. Impulse responses from a VAR are examined for evidence of business cycle transmission, and recursive least squares estimates are used to check for structural change in the relationship. Figures are used to graphically demonstrate these relationships and have been collected in an appendix, which can be found at the end of the text.While the two countries engage in a close trading relationship, the two economies are found to be only somewhat interdependent in macroeconometric terms. Japan is found to transmit some of its business cycle fluctuations to Australia, but there is little reverse transmission.     

Money demand in China and time-varying cointegration

Many studies analyze the money demand using a (fixed coefficient) cointegrating regression model, which may not be appropriate to deal with the money demand of a transition economy like China. This paper investigates this issue using a time-varying cointegration approach based on the quarterly data from 1996 to 2009. We find some interesting results: (i) the estimates of the income elasticities are between 0.60 and 0.75, which are comparable with the previous studies; (ii) the estimated interest rate elasticity supports the argument that the overall effect of the interest rate on the money holding is weak although there are some mild evidences that it has been strengthened in recent years; (iii) the substitution effect of equity asset dominates the wealth effect, especially, during the bullish market period. Our result is robust to the alternative choices of the scale or opportunity cost variables and shows that omission of the stock prices in the money demand function would possibly yield a misspecification problem.     

What causes business cycles? Analysis of the Japanese industrial production data

We explore what causes business cycles by analyzing the Japanese industrial production data. The methods used are spectral analysis and factor analysis. Using the random matrix theory, we show that two largest eigenvalues are significant. Taking advantage of the information revealed by disaggregated data, we identify the first dominant factor as the aggregate demand, and the second factor as inventory adjustment. They cannot be reasonably interpreted as technological shocks. We also demonstrate that in terms of two dominant factors, shipments lead production by four months. Furthermore, out-of-sample test demonstrates that the model holds up even under the 2008–2009 recession. Because a fall of output during 2008–2009 was caused by an exogenous drop in exports, it provides another justification for identifying the first dominant factor as the aggregate demand. All the findings suggest that the major cause of business cycles is real demand shocks.     

Asian holding of US Treasury securities: Trade integration as a threshold

This paper empirically investigates if there have been any shifts in regimes with Asian holding of US long-term Treasury securities with particular attention paid to the role of growing regional integration in trade. A panel regression estimation of eight Asian countries for 1998–2004 confirms the striking persistency of the portfolio weight of US Treasury securities. It also reveals, without a surprise, that the traditionally strong trade link with US as well as exchange rate regime and volatility of local currency bond index explain observed overinvestment in US Treasury securities deviating from what can be warranted by the market share of the US Treasury securities. What is interesting, however, is the estimated regime switches as found when examined with a threshold estimation (Hansen, 1999). We find three thresholds which divide the sample into four regimes—a decreasing persistency as intraregional trade link becomes tighter.
