External shocks and Japanese business cycles: Evidence from a sign-restricted VAR model

This study investigates the sources of Japanese business fluctuations since the 1990s, taking into account both external shocks (e.g., risk premium and foreign demand shocks) and domestic supply and demand shocks. We use the sign-restricted VAR model based on the theoretical model to identify these shocks. The presented results show that approximately 30–50% of the forecast error variances in output can be explained by external shocks. Further, we demonstrate that supply shock is the main influencing factor in Japanese business fluctuations throughout the sample period and that the role of external shocks has been growing in the post-Lehman period, including the effect of the Great East Japan Earthquake.     

An estimated search and matching model of the Japanese labor market

This paper studies how well a simple search and matching model can describe aggregate Japanese labor market dynamics in a full information setting. We develop a discrete-time search and matching model with a convex vacancy posting cost and three shocks: productivity, separation, and markup shocks. We use the model as a data-generating process for our empirical analysis and estimate it by using Bayesian methods. The model is successful in replicating the behavior of unemployment and vacancies in Japan. However, we also find that the success of the model relies on shock processes that are not empirically plausible.     

Great Moderation in the Japanese economy

This paper investigates the contribution of technology and nontechnology shocks to the changing volatility of output and labor growth in the postwar Japanese economy. A time-varying vector autoregression (VAR) with drifting coefficients and stochastic volatilities is modeled and long-run restriction is used to identify technology shocks in line with Galí (1999) and Galí and Gambetti (2009). We find that technology shocks are responsible for significant changes in the output volatility throughout the total sample period while the volatility of labor input is largely attributed to nontechnology shocks. The driving force behind these results is the negative correlation between labor input and productivity, which holds significantly and persistently over the postwar period.     

News shocks and Japanese macroeconomic fluctuations

Are the changes in the future technology process, the so-called “news shocks,” the main contributors to the macroeconomic fluctuations in Japan over the past forty years? In this paper, we take two structural vector-auto-regression (SVAR) approaches to answer this question. First, we quantitatively evaluate the relative importance of news shocks among candidate shocks, estimating a structural vector-error–correction model (SVECM). Our estimated results suggest that the contribution of the TFP news shocks is nonnegligible, which is in line with the findings of previous works. Furthermore, we disentangle the source of news shocks by adopting several kinds of restrictions and find that news shocks on investment-specific technology (IST) also have an important effect. Second, to minimize the gap between the SVAR approach and the Bayesian estimation of a dynamic stochastic general equilibrium model, we adopt an alternative approach: SVAR with sign restrictions. The SVAR with sign restrictions reconfirms the results that the news shocks are important in explaining the Japanese macroeconomic fluctuations.     

A Quantitative Assessment of the Role of Incomplete Asset Markets on the Dynamics of the Real Exchange Rate

I develop a two-country New Keynesian model with capital accumulation and incomplete international asset markets that provides novel insights on the effect that imperfect international risk-sharing has on international business cycles and RER dynamics. I find that business cycles appear similar whether international asset markets are complete or not when driven by a combination of non-persistent monetary shocks and persistent productivity (TFP) shocks. In turn, international asset market incompleteness has sizeable effects if (persistent) investment-specific technology (IST) shocks are a main driver of business cycles. I also show that the model with incomplete international asset markets can approximate the RER volatility and persistence observed in the data, for instance, if IST shocks are near-unit-root. Hence, I conclude that the nature of shocks, the extent of financial integration across countries and the existing limitations on asset trading are central to understand the dynamics of the real exchange rate and the endogenous international transmission over the business cycles.     

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.     

Fiscal stimulus and labor market dynamics in Japan

The paper studies the effects of fiscal expansion on the Japanese labor market. First, using a structural VAR model, we find that the unemployment rate falls and employment rises following an increase in government spending. We also find that fiscal expansion affects flows in and out of unemployment. While an increase in government spending increases the job-finding rate, it reduces the separation rate. We then incorporate search and matching frictions into a standard dynamic general equilibrium model, and study whether the model can explain what we observed in data. While the model fails to predict the exact size of the impact of government spending shocks on the Japanese labor market variables, it can consistently capture the empirical pattern of responses of labor market variables to shocks.     

The effect of inheritance receipt on individual labor supply: Evidence from Japanese microdata

This paper examines the effects of wealth on individual labor supply by considering inheritance receipts as an exogenous change in household wealth. Using Japanese microdata consisting of individuals aged 26–51, we find that (i) while men’s probability of working does not respond to inheritance receipt, women’s probability of working decreases; and (ii) in the case of most respondents the receipt of an inheritance seems to be unanticipated. We also test the unitary household model using information on respondents’ spouses. The results indicate that who received an inheritance influences the labor supply decision of each household member, meaning that we find no support for the unitary model.     

A comparison of the Japanese and U.S. business cycles

This paper constructs a consistent set of quarterly Japanese data for the 1960–2002 sample period and compares properties of the Japanese and U.S. business cycles. We document some important differences in the adjustment of labor input between the two countries. In Japan most of the adjustment is in hours per worker of males and females and also in employment of females. In the U.S. most of the adjustment is in employment of both males and females. We formulate, estimate, and analyze a model that makes the distinction between the intensive and extensive margin and allows for gender differerences in labor supply. A weak empirical correlation between hours per worker and employment in Japanese data is a puzzle for our theory.     

Policy Shocks and Macroeconomic Fluctuations in a Two‐country Dynamic Stochastic General Equilibrium Model: Evidence from China*

In this paper, we construct a two‐country dynamic stochastic general equilibrium model to investigate the sources of business cycles in China and the contributions of policy shocks in economic fluctuations. The empirical results from Bayesian estimation show that, apart from the traditional supply and demand shocks, monetary and fiscal policy shocks also play important roles in determining China's economic fluctuations. In addition, we find significant feedback effects between monetary and fiscal policies in China, indicating that policy coordination is an important feature of China's monetary and fiscal policies. Overall, these results not only shed new light on the policy factors behind China's economic fluctuations, but also provide new evidence that is helpful for understanding the policy transmission mechanisms in China.     

Persistence of business cycles in multisector real business cycle models

In this paper we explore whether the changing composition of output in response to technology shocks can play a significant role in the propagation of shocks over time. For this purpose we study two multisector real business cycle models, with two and three sectors. We find that, although the two-sector model requires a high intertemporal elasticity of substitution of consumption to match the various dynamic properties of US macroeconomic data, the three-sector model has a strong propagation mechanism under conventional parameterizations, as long as the factor intensities in the three sectors are different enough.     

Automatic stabilizers in the Japanese tax system

When studying the role of taxes as an automatic stabilizer, excluding the effects of discretionary tax reform is troublesome. A fruitful approach to identifying tax movements over business cycles would be to utilize cyclical information. From this perspective, we exploit wavelets in order to characterize the automatic response of taxes to output at business cycle frequencies in the postwar Japanese economy. We find the presence of automatic stabilizers in the Japanese tax system under the influence of relatively high output volatility but the absence of such stabilizers during the period of the “Great Moderation” in Japan in the 1980s.     

Welfare Implications of Currency Integration: Labor Mobility and Pricing-to-Market

In this paper, we examine the welfare cost of renouncing monetary policy autonomy in a model that includes labor mobility and pricing-to-market (PTM) behavior in firms. We find that renouncing monetary policy autonomy becomes a cost of currency integration when the consumption basket weights differ between candidate countries and when country-specific total factor productivity (TFP) shocks hit economies, even when the union fulfills the classic optimum currency area theory of labor mobility. We also found that a firm's PTM behavior has a significant effect on the welfare implications of currency integration combined with labor mobility. For instance, currency integration does not produce greater welfare losses in the PTM case (where the labor input weights differ across member countries and asymmetric labor disutility shocks occur), although greater welfare losses arise in the case of producer currency pricing.     

Hot Money and Business Cycle Volatility： Evidence from China

This paper investigates the link between hot money and business cycle volatility in China from January 1997 to December 2009. Using the structural vector error correction model we find a considerable degree of long-run cointegration and bidirectional causality effects between hot money and business cycle volatility. The speculative shocks are found to temporarily promote China＇s economic growth, but also to exacerbate business cycle volatility. The liquidity shock stemming from hot money is shown to be the primary factor responsible for the significantly enhanced fluctuation in business cycles during the most recent global financial crisis period This could be detrimental to the smooth operation of financial markets. Therefore, informing future policies, it is critical for policy-makers to take precautions against the speculative factors.     

SYNCHRONISATION BETWEEN SOUTH AFRICA AND THE U.S.: A STRUCTURAL DYNAMIC FACTOR ANALYSIS

This paper studies the synchronisation of the South African and the US cycles and transmission channels through which supply and demand shocks from the US affect economic activity in South Africa in a structural dynamic factor model framework. We find, using the full-sample period, US supply shocks are transmitted to South Africa through business confidence and imports of goods and services; while US demand shocks are transmitted via interest rates, stock prices, exports of goods and services, and real effective exchange rates. Second, there is a decrease in integration over time translated by a drop in synchronisation of cycles. The impact of an increase in comovement of GDP is outweighed by the structural reforms initiated by the government after the end of apartheid. Finally, the idiosyncratic component still plays an important role in the South African economy.     

The boom and the bust of the Japanese economy: A quantitative look at the period 1980–2000

In this paper we quantitatively investigate the boom and the bust of the Japanese economy during 1980–2000 using the business cycle accounting technique. This method helps us identify the distortion margins called “wedges” that played a significant role in accounting for the output fluctuations. Applying our model to Japan, we find that efficiency and investment wedges can almost wholly account for output increases of the 1980s. Labor wedges by themselves would have caused a recession beginning in late 1980s but was overwhelmed by the positive impact of efficiency and investment wedges. In the 1990s, efficiency, labor and investment wedges all contributed to the recession. We next extend the literature by conducting robustness tests to investigate the sensitivity of BCA results to small modifications in methodology.     

The driving forces of China's business cycles: Evidence from an estimated DSGE model with housing and banking

We study the approximate sources of China's business cycles in an estimated dynamic stochastic general equilibrium (DSGE) model with housing and banking. The model replicates well the volatility and cyclicality of key macroeconomic variables observed in the past two decades in China. A host of shock decomposition exercises demonstrate that, among the shocks being considered, both financial and housing shocks are driving China's business cycles, accounting for a particularly large fraction of the variance in most macroeconomic and financial variables at the business cycle frequencies. In particular, the capital quality, housing demand, and loan-to-value shocks display prominent contributions to the business cycle fluctuations. Moreover, there exists substantial interactions between the banking and housing sectors in China, where the collateral constraint and the financial constraint amplify with each other. The results shed new light in the understanding of China's business cycles, and may serve as a useful benchmark for future quantitative analyses of China's macroeconomic fluctuations using DSGE frameworks.     

EMPLOYMENT,CAPITAL, AND PRODUCTIVITY DYNAMICS: EVIDENCE FROM THE MANUFACTURING SECTOR IN URUGUAY

Using a sample of Uruguayan manufacturing establishments we analyze employment, capital, and productivity dynamics over a period of currency appreciation; changes in trade policy; and changes in the institutional setting of wage negotiations. As the relative capital–labor price ratio fell, capital intensity increased. At the same time, there was an increase in labor and total factor productivity. Creation and destruction rates were relatively high and pervasive over time, sectors, establishment size, and establishment age, with exits explaining a sizeable part of destruction rates. Most of the excess reallocation was due to movements “within” rather than “between” sectors. Thus, high reallocation rates were linked to establishment‐level heterogeneity rather than aggregate shocks.     

What accounts for Chinese Business Cycle?

This paper investigates the sources of economic fluctuations in China since its reform that started in 1978. Using the framework of a standard neoclassical open economy model with time-varying frictions (wedge), we study the relative contribution of the efficiency, labor, investment and foreign debt wedges to the business cycles of China. The business accounting procedure suggests that productivity best explains the behavior of aggregate economic variables in China throughout the period of 1978–2006. The labor wedge plays a major role in explaining the movement of labor force. The foreign debt wedge and investment wedge primarily affect the composition of output, but their role in explaining the movement of output is modest. Our results suggest that the focus of government policies should be to combat the problems of inefficient factor utilization and labor market rigidity.     

The China shock and job reallocation in Japan

This study investigates the characteristics of manufacturing job reallocation in Japan induced by import shocks from China during 1996–2016. Three types of import shocks are considered: direct, upstream, and downstream. Some salient features of job reallocation include decrease in total jobs from direct import, increase in small establishments’ jobs from downstream import, and job changes mainly induced establishments’ entry and exit. The sizeable difference of implied job changes in industry-level analysis and those in region-level analysis attributes to the local reallocation and aggregate demand effects determined by regional characteristics. The total job effect of three import shocks is negative in all cases examined. The method of decomposing job changes into detailed job flows and further into industry and regional factors, proposed in this study, enabled obtaining a clearer view of job reallocation and how import shocks travel through labor market.
