The Pricing of Critical Applications in the Internet

A number of authors have recently proposed techniques for pricing access to Internet resources in the case of congestion. However, these approaches do not take into account the fact that some applications necessitate guaranteed capacity over a relatively long period of time. This paper discusses some elements of the theory of a mechanism that would accommodate such applications. We begin by reviewing both current practice and theory. We then build infinite horizon stationary models with asymmetry of information, which we first use to show the limits of smart markets (McKie-Mason and Varian). Finally, in a very simplified model, we compute the optimal mechanism, and in a specific example, we show that the optimal mechanism favors the high-type long-term user. J. Japan. Int.

Transition from School to Work in Japan

Using retrospective data of young people's work experience in Japan, this paper found that initial labor market conditions, i.e., when workers first enter the labor market after permanently leaving school, have a significant lasting impact on the employment experiences of workers in their teens and twenties. An increase in the unemployment rate at the time of labor market entry reduces the probability of gaining full-time regular employment and, more important, increases the future probability of workers of leaving employers by lowering the quality of job matches. It was also found that the vocational guidance or recommendations workers received at school could be effective in raising the quality of job matches. The adverse effect of initial unemployment rates on employment opportunities was most profoundly observed among female college graduates. J. Japan. Int. Econ., December 2001, 15(4), pp. 465–488.

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.

Unemployment and Labor Market Institutions: An Empirical Analysis

The development of the unemployment rate differs substantially between OECD countries. In this paper we investigate to what extent these differences are related to labor market institutions. In our analysis we use data of eighteen OECD countries over the period 1960–1994 and show that the way in which institutions interact is important. J. Japan. Int.

The End of Lifetime Employment in Japan?: Evidence from National Surveys and Field Research

Using both quantitative data from national surveys and qualitative data from our recent field research, this paper provides evidence on the recent transformation of Japan's celebrated practice of lifetime employment (or implicit long-term employment contracts for the regular workforce). Overall, contrary to the popular rhetoric of the end of lifetime employment, evidence points to the enduring nature of this practice in Japan. Specifically, we find little evidence for any major decline in the job retention rates of Japanese employees from the period prior to the burst of the bubble economy in the late 1980s to the post-bubble period. In general, our field research corroborates the main finding from the job retention rates by describing vividly that large firms in Japan have been trying to accomplish their restructuring and downsizing targets by relying heavily on transfers of their employees to their subsidiaries and related firms and hiring cuts, thus avoiding layoffs. Last, the burden of downsizing appears to fall disproportionately on young workers and middle-age workers with shorter tenure. J. Japan. Int. Econ., December 2001, 15(4), pp. 489–514.

Fiscal Reconstruction and Local Interest Groups in Japan

This paper investigates the politicoeconomic properties of the fiscal reconstruction process in Japan by analyzing the dynamic game among local interest groups with concessions of region-specific privileges. Free-riding behavior of local interest groups brings numerous deficits. Our empirical evidence indicates that local privileges were powerful in the 1990s, which is the main reason fiscal reconstruction did not perform very well in the 1990s. J. Japan. Int.

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.

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.

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.

The Fiscal Investment and Loan Program in Transition

This paper discusses the adequacy of the activities of the Fiscal Investment Loan Program (FILP) agencies after the fundamental reform in April 2001, which disconnected postal savings and public pension reserves from the FILP. It is found that many ideas of justifying the government interventions to the financial sector have now lost their relevancy. The activity of government financial intermediaries should be streamlined. Among infrastructure construction projects, the most serious part of welfare loss lies on national motorway construction, which is estimated to be about 14.5 trillion yen of welfare loss. J. Japan.

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.

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.

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.

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.

To Spend the U.S. Government Surplus or to Increase the Deficit? A Numerical Analysis of the Policy Options

This paper provides a numerical analysis of the likely benefits from adopting alternative ways of reducing the projected fiscal surplus (as of the summer 2001) in the United States economy. Calibrating a small growth model, our results suggest that investing the surplus in public capital is likely to yield the greatest long-run welfare gains, although decreasing the capital income tax is only marginally inferior. Both these options dominate increasing government consumption expenditure or decreasing the tax on labor income. By shifting resources from consumption toward capital the two superior policies involve sharp intertemporal tradeoffs in welfare; significant short-run welfare losses are more than compensated by large long-run welfare gains. By contrast, the two inferior options are gradually welfare-improving through time. A crucial factor in determining the benefits of reducing the government surplus through spending is the size of the government sector relative to the social optimum. We find that the second-best optimum is to increase both forms of government expenditure to their respective social optima, while at the same time restructuring taxes by reducing the tax on capital and raising the tax on wage income to achieve the targeted reduction in the surplus.

Sectoral Price Movements under the Yen Appreciation

This paper analyzes the movements of tradable goods prices in Japan. The import price indices and the export price indices are matched with the domestic wholesale price indices at the most detailed level available for Japan, and the pricing behavior in the yen appreciation period (1985–1995) is examined. In the import-side analysis, we investigate how far the price movements under currency appreciation deviate from the law of one price. We find that internal–external price differentials have surprisingly expanded for most of the products since 1985. For a number of commodities, the import prices do not decline as far as the exchange rate appreciates, and the domestic wholesale prices do not decrease as far as the import prices decline. Although the expanded price gaps cannot necessarily be interpreted as a result of deliberate trade barriers, they suggest that some sort of handicap is imposed on imported goods and the large fraction of rent generated by the yen appreciation is intercepted in the middle. In the export-side analysis, the relationship between the globalization of firms' activities and export pass-through is investigated. Our cross-sectional regression analysis indicates that the export path-through rates tend to be low when the value added ratios of foreign production of Japanese firms are high. Low export pass-through under currency appreciation is often interpreted as a result of firms' attempts to keep their foreign market share, but the globalization of firms' activities may be another important factor in lowering the pass-through.J.

Trade and the Wage Structure in the Presence of Price Differentials in the Product Market: The Japanese Labor Market 1965–1990

The decomposition of demand into domestic, export, and import components in a cross-industry study of 18 two-digit manufacturing industries suggests that export growth has less of an impact on interindustry wage differentials than the equivalent growth in domestic demand. The difference seems to be greatest in the case of full-time workers in large firms. This result for Japan is different from those of similar studies for the United States and is consistent with a model of industry rent-sharing with domestic–international price differentials in the product market.J.

Determinants of Individual-Firm Markup in Japan: Market Concentration, Market Share, and FTC Regulations

This paper estimates individual firm level markup for more than 400 major manufacturing firms in Japan. Our estimates suggest the presence of significant market power for most of these firms, due not only to market concentration but also to the firms' own market shares, as well as advertizing and sales promotion efforts. The paper then goes on to assess systematically the impact on estimated markups of regulatory measures taken by the Fair Trade Commission (FTC) of the Japanese Government. We find that non-punitive FTC activities are directed toward the right targets and are reasonably effective, whereas injunctions, the strongest measure endowed to the FTC, has essentially no effect on the markups of firms in our sample.

THE ECONOMICS OF IMPORT PARITY PRICING: A PEDAGOGICAL NOTE

This paper demonstrates that pricing to import parity is not necessarily prima facie evidence of the exercise of market power. It is shown that in the presence of imports both market structures, perfect competition and monopoly, can price to import parity. If markets can be segmented enabling the firm to discriminate between the export and domestic market it is shown that the imperfectly competitive firm can differentially price. Furthermore, as the number of domestic firms is increased, and if these firms are able to segment the market, the differential between domestic and foreign prices is reduced. The import parity price may or may not be charged in the domestic market. A measure of the exercise of market power is therefore the differential between export parity and the domestic price.     

Are China's energy markets cointegrated?

The paper investigates energy price co-movement over the period 01/1999–12/2005 for China as a whole, and over sub-periods and for seven regions, using panel unit root and panel cointegration tests developed by Pedroni (1999, 2004). The results suggest that not all energy sources are spatially homogenous in prices and the processes of energy price cointegration are different over sub-periods; over groups of fuels; and over regions. Coal and electricity prices have co-moved since 2003 while gasoline and diesel prices have co-moved since 1997. The results show that there are clearly variations in the emergence of energy price co-movement over regions, implying that regional fuel markets have emerged in China. Important lessons that can be learnt from the results are that an energy market has, to some extent, already emerged in China and, as a result, energy prices are substantially less distorted than before. If correct, these findings have significant global implications both in terms of future emission reductions, emission trading and trade negotiations where China should be treated as a ‘market driven economy’.
