Should We Be Afraid of Friedman's Rule?

Should one think of zero nominal interest rates as an undesirable liquidity trap or as the desirable Friedman rule? I use three different frameworks to discuss this issue. First, I restate H. L. Cole and N. Kocherlakota's (1998, Fed. Res. Bank Minn. Quart. Rev., Spring, 2–10) analysis of Friedman's rule: short run increases in the money stock—whether through issuing spending coupons, open market operations, or foreign exchange intervention—change nothing as long as the money stock shrinks in the long run. Second, two simple Keynesian models of the inflationary process with a zero lower bound on nomianl interest rates imply either that deflationary spirals should be common or that a policy close to the Friedman rule and thus some deflation is optimal. Finally, a formal baby-sitting coop model implies multiple equilibria, but does not support the injection of liquidity to restore the good equilibrium, in contrast to P. Krugman (1998, Slate, August 13). J. Japan. Int. Econ., December 2000, 14(4), pp. 261–303.

On the Role of Monetary Policy in a Deflationary Economy: The Case of Japan

In this paper we review the role of monetary policy for a country facing deflationary pressure based on the recent experience of the Japanese economy. We discuss economic background of inflation policy in Japan and analyze the impacts of the policy. We made simple calculations regarding how much the debt of selected companies and government can be reduced by mild inflation. Noting that the Fisher effect does not work perfectly under liquidity traps, the effect of inflation on debt issue appears quite large. To maintain controllable stable inflation, inflation targeting is a good candidate for the policy rule. J. Japan. Int. Econ., December 2000, 14(4), pp. 238–260.

Efficient Monetary Policy Design near Price Stability

Using dynamic programming methods, we study the design of optimal monetary policy in a simple, calibrated open-economy model and evaluate the effect of the liquidity trap generated by the zero bound on nominal interest rates. We show that the optimal policy near price stability is asymmetric. As inflation declines, policy turns expansionary sooner and more aggressively than would be optimal in the absence of the zero bound. This introduces an upward bias in the average level of inflation. We also discuss operational issues associated with the interpretation and implementation of policy at the zero bound in relation to the recent situation in Japan. J. Japan. Int.

The Role of Monetary Policy in Japan: A Break in the 1990s?

This article documents time series evidence suggesting the case for a possible structural break in the role of Japan's monetary policy during the 1990s. It uses a simple vector autoregressive framework and offers some suggestive results: While a persistent effect of monetary policy on real output is detected over the full sample of 1975–1998 and the subsample that ends in 1993, such effect disappears with the recent subsample of the 1990s. The stability analysis also provides more specified evidence that there is a break in the reduced form dynamic system in 1995. Some interpretations are offered to intuitively support these findings.

Quantitative easing and Japanese bank equity values

One of the primary motivations offered by the Bank of Japan (BOJ) for its quantitative easing program—whereby it maintained a current account balance target in excess of required reserves, effectively pegging short-term interest rates at zero—was to maintain credit extension by the troubled Japanese financial sector. We conduct an event study concerning the anticipated impact of quantitative easing on the Japanese banking sector by examining the impact of the introduction and expansion of the policy on Japanese bank equity values. We find that excess returns of Japanese banks were greater when increases in the BOJ current account balance target were accompanied by “non-standard” expansionary policies, such as raising the ceiling on BOJ purchases of long-term Japanese government bonds. We also provide cross-sectional evidence that suggests that the market perceived that the quantitative easing program would disproportionately benefit financially weaker Japanese banks. J.

Monetary Policy, Credit, and Real Activity: Evidence from the Balance Sheet of Japanese Firms

We analyze the mechanism of monetary transmission in the Japanese economy by using the quarterly time series data disaggregated by firm size. In particular we examine the channels through which monetary policy influences the firm's fixed investment with special focus on the firm's land. We estimate the vector autoregressive model where we encompass two competing hypotheses on the monetary transmission: monetary and credit channels. Our evidence is in support of the credit channel. We find that land has played a vital role in the monetary transmission, especially for small firms. Moreover, we find that fall of land value in 1990s weakened the efficacy of monetary policy considerably. J. Japan. Int. Econ., December 2000, 14(4), pp. 385–407.

Budgetary Consolidation in Europe: Quality, Economic Conditions, and Persistence

In this article we study the importance of the quality of fiscal adjustments and macroeconomic conditions for the persistence of budgetary consolidations. In contrast to previous work in this area, we do not arbitrarily predefine a measure of persistence to evaluate consolidation “success.” By employing duration analysis techniques, the length of a consolidation spell is rather determined endogenously. Our results based on a sample of industrialised OECD countries show that “consolidation fatigue” and the quality of fiscal consolidations are indeed important determinants of their longevity. Moreover, high debt–GDP ratio and fiscal tightening in other OECD countries raise the likelihood of consolidations to persist. Applying our results to European countries in the 1990s provides only weak evidence suggesting that the Maastricht process contributed much to the fiscal consolidations observed in Europe during the 1990s.

Output-Inflation Trade-Off at Near-Zero Inflation Rates

The purpose of this paper is to provide new evidence about the cost of near-zero inflation using Japanese data. We test the hypothesis that the short-run Phillips curve becomes flatter as the rate of inflation approaches zero. In implementing the test, we pay special attention to how to control for other factors affecting the rate of inflation. First, we use the skewness of the distribution of relative-price changes as a measure of supply shocks. Second, we use information contained in the cross-prefecture Phillips curve to control for changes in the expected rate of inflation. Through a series of empirical analyses, we find evidences consistent with the hypothesis. In particular, we find that the estimated slope in the 1990s is smaller than before. J. Japan. Int.

Fiscal Policy Effectiveness in Japan

The effectiveness of fiscal policy in Japan over the past decade has been a matter of great controversy. We investigate the effectiveness of Japanese fiscal policy over the 1976–1999 period using a structural VAR analysis of real GDP, tax revenues, and public expenditures. We find that expansionary fiscal policy, whether in the form of tax cuts or of public works spending, had significant stimulative effects. Using a new method of computing policy multipliers from structural VARs, we calculate that the multiplier on tax cuts is about 25% higher at a four-year horizon than that on public works spending, though both are well in excess of one. A historical decomposition reveals that Japanese fiscal policy was contractionary over much of the 1990s, and a significant proportion of the variation in growth can be attributed to fiscal policy shocks; accordingly, most of the run-up in public debt is attributable to declining tax revenues due to the recession. Examining savings behavior directly, we find limited evidence of Ricardian effects, insufficient to offset the short-term effects of discretionary fiscal policy. J. Japan. Int.

Invoicing currency and the optimal basket peg for East Asia: Analysis using a new open economy macroeconomic model

An important characteristic of trade in Asia is that the US dollar is the dominant invoicing currency. This fact might have a consequence on the region's choice of the currency regime. To investigate this possibility, I develop a three country “new open economy macroeconomics” model that consists of East Asia, Japan, and the US. Assuming that East Asia pegs its currency to a basket of the other two's currencies, the optimal basket weights are derived numerically. It is shown that the weights under a realistic invoicing pattern are drastically different from those in the textbook case of “producer currency pricing.” J. Japanese Int.

Life cycle and bequest savings A study of Japanese and U.S. households based on data from the 1984 NSFIE and the 1983 survey of consumer finances

This paper investigates whether the elderly save or dissave in light of two newly available sets of cross-section micro data, the 1983 “Survey of Consumer Finance” for the United States and the 1984 “National Survey of Family Income and Expenditure” for Japan. Contrary to dominant earlier findings we find for the United States that families after retirement dissave on average about a third of their peak wealth by the time of death, leaving the rest (mostly their homes) as bequests. For Japan, special handling is made to eliminate possible sample selection bias due to the different economic characteristics of the elderly forming independent households and those living with children. We find that the elderly belonging to both groups continue to save, and moreover, there appear to be significant signs of ongoing wealth transfer between the generations. The data in both countries also show that the elasticity of saving with respect to a life time income measure is significantly greater than unity, and more strongly so within higher age groups. J.

Fluctuations in Unemployment and Industry Labor Markets

Throughout the 1990s, and particularly in the mid- to late-1990s, the Japanese employment situation went from bad to worse. We investigate the causes of rising unemployment in Japan, using data on individual workers from the “Special Survey of the Labor Force” between 1988 and 1999. This research focuses on the effect of labor market segmentation by industry on labor flows. Our findings reveal that unemployment in the construction industry and, more recently, in the service industry has contributed greatly to the national unemployment rate. We also find that most successful job transfers occur within the same industry, even though workers may experience some periods of unemployment. Finally, our results show that labor market conditions in each industry affect the probability that a worker will fall into unemployment as well as the probability that an unemployed worker will find new employment. These findings suggest that the Japanese labor market is segmented by industry and this segmentation contributed to the worsening unemployment in Japan. J. Japan. Int.

Stock market rationality and price volatility: Tests using Japanese data

This paper tests the stock market rationality hypothesis, which implies that a stock price is determined as the discounted sum of optimally forecasted future dividends. Mankiw-Romer-Shapiro volatility tests and new volatility tests which do not use the unobservable “ex post rational price” are applied to the data from a stock market in Japan. A Hausman type specification test of the market rationality hypothesis is also developed and applied to the data. The results suggest that we cannot reject the hypothesis that the Japanese stock market is rational. A couple of variance inequalities are violated by the data but the violation does not seem to be significant. J. Japan. Int. Econ., December 1987, 1(4), pp. 441–462.

Measuring the Liquidity Effect: The Case of Japan

In this paper, we measure the liquidity effect in Japan, complementing the work done by F. Hayashi (2001, Int. Econ. Rev.42, 287–316) and compare it to the liquidity effect in the United States. Since institutional features are similar across these two countries, we apply J. Hamilton's (1997, Amer. Econ. Rev.87, 80–97; 1998, Carnegie-Rochester Conf. Ser. Public Pol. 49, 1–44) methodology to estimate the liquidity effect for each day of the maintenance period. Detailed daily data supplied by the Bank of Japan enable us to obtain more accurate estimates for Japan. Our key findings, which are not found in F. Hayashi (2001, Int. Econ. Rev.42, 287–316) are as follows: (1) On the final day of a reserve maintenance period, both countries show the strongest evidence of the liquidity effect, and (2) in both countries the liquidity effect tends to be larger and more statistically significant toward the end of the period.

Nonlinear Aspects of Goods-Market Arbitrage and Adjustment: Heckscher''s Commodity Points Revisited

We propose that analysis of purchasing power parity (PPP) and the law of one price should explicitly take into account the possibility of “commodity points”—thresholds delineating a region of no central tendency among relative prices, possibly due to lack of perfect arbitrage in the presence of transaction costs and uncertainty. More than 80 years ago, Heckscher stressed the importance of such incomplete arbitrage in the empirical application of PPP. We devise an econometric method to identify commodity points. Price adjustment is treated as a nonlinear process, and a threshold autoregression offers a parsimonious specification within which both thresholds and adjustment speeds are estimated by maximum likelihood methods. Our model performs well using post-1980 data, and yields parameter estimates that appear quite reasonable: adjustment outside the thresholds might imply half-lives of price deviations measured in months rather than years, and the thresholds correspond to popular rough estimates as to the order of magnitude of actual transport costs. The estimated commodity points appear to be positively related to objective measures of market segmentation, notably nominal exchange rate volatility.J. Japan Int.

The Euro and International Equity Flows

We use a new panel data set on bilateral gross cross-border equity flows between 14 countries. We fit a “gravity model” to these data and a strictly comparable set of data for manufactures trade between these countries. The results are strikingly similar, although the coefficient on the distance variable is lower for equity than for trade flows (but still highly significant). We use the results to throw some light on the likely consequences of unifying the European equity markets.J. Japan. Int. Econ.December 1998,12(4), pp. 406–423.

Confronting the Mystery of Urban Hierarchy

The size distribution of cities in the United States is startlingly well described by a simpler power law: the number of cities whose population exceedsSis proportional to 1/S. This simple regularity is puzzling; even more puzzling is the fact that it has apparently remained true for at least the past century. Standard models of urban systems offer no explanation of the power law. A random growth model proposed by Herbert Simon 40 years ago is the best try to date—but while it can explain a power law, it cannot reproduce one with the right exponent. At this point we are in the frustrating postion of having a striking empirical regularity with no good theory to account for it.J. Japan. Int. Econ., December 1996,10(4), pp. 399–418.

Deficit Spending in the Nazi Recovery, 1933–1938: A Critical Reassessment

This paper examines the effects of deficit spending and work-creation on the Nazi recovery, employing archival data on the public deficit and modern time series techniques. Although deficit spending was tried and full employment was reached within four years, the fiscal impulse generated by the deficits does not appear to have driven the speed of recovery. VAR forecasts of output using fiscal and monetary policy instruments suggest only a minor role for active policy during the recovery. Nazi policies deliberately crowded out private demand to ensure high rates of rearmament. Military spending dominated civilian work-creation already in 1934. Investment in autobahn construction was minimal during the recovery and gained momentum only in 1936 when full employment was approaching. Continued fiscal and monetary expansion after that date may have prevented the economy from sliding back into recession. We find some effects of the Four Years Plan of late 1936, which boosted government deficits further and tightened public control over the economy. J. Japan. Int.

Government Deficit, Public Investment, and Public Capital in the Transition to an Aging Japan

This paper examines the effects of government deficits, public investment, and public capital on welfare in the transition to an aging Japan by applying a simulated general equilibrium growth model. One of the main results of this paper is that targeting only high economic growth would mislead us as to economic policies, and that a policy to reduce future government deficits is most preferable for almost all generations, even though a cut in future deficits must be followed by a decrease in public investment, thus a decrease in public capital in the future.

Who bears the burden of social insurance? Evidence from Japanese health and long-term care insurance data

Using the society-managed health insurance data, which is cross-sectional time-series and covers 1670 health insurance societies for seven years (FY1995–2001), we found for the first time in Japan that the majority of the employers' contribution to health insurance is shifting back onto the employees in the form of wage reduction. On the other hand, we cannot find such evidence for the contribution to long-term care insurance using a two-year (FY2000–2001) panel data set. The difference can be theoretically explained by how employees value the contribution relative to social security benefits they enjoy. J. Japanese Int. Economies 18 (4) (2004) 565–581.
