This paper explores the nature of postwar business cycles in Japan. Our basic strategy is to study different production behaviors of various manufacturing industries over business cycles. We are particularly interested in the problems of whether only monetary shocks are important and, if not, what kind of real shocks are important. We conclude that purely monetary theory is inadequate, and that construction activities were major causes of aggregate fluctuations in the pre-first oil shock period of rapid growth. We also present some evidence suggesting that real business cycle theory is implausible.  相似文献

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.  相似文献

This paper investigates the synchronization of Hong Kong's economic growth with mainland China and the US. We identify trends of economic growth based on the permanent income hypothesis. Specifically, we first confirm whether real consumption in Hong Kong and mainland China satisfies the permanent income hypothesis, at least in a weak form. We then identify the permanent and transitory components of income of each economy using a simple state-space model. We use structural vector autoregression models to analyze how permanent and transitory shocks originating from mainland China and the US affect the Hong Kong economy, and how such influences evolve over time. Our main findings suggest that transitory shocks from the US remain a major driving force behind Hong Kong's business cycle fluctuations. On the other hand, permanent shocks from mainland China have a larger impact on Hong Kong's trend growth.  相似文献

This paper discusses causes of capital flows in Korea and Mexico. Both countries received substantial amounts of foreign capital in the late 1980s and early 1990s. International capital helped these countries achieve a higher standard of living and faster economic growth. However, undesirable macroeconomic effects such as appreciation of real exchange rate and widening current account deficits usually accompany foreign capital inflows. The vector autoregressive (VAR) method is applied to investigate the underlying shocks causing the capital inflows. The main findings are that the U.S. business cycle and shocks to foreign interest rates account for more than 50% of capital inflows to both countries in the past two decades.  相似文献

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.  相似文献

Abstract

Staggered wage-setting and price-setting have frequently been used to construct business cycle models that can replicate long-lasting real effects of monetary shocks. We examine how the two seemingly equivalent sources of nominal rigidities compare in generating persistence in real output following monetary expansion. We show that staggered wage-setting is in general better able to generate persistence, because it can lower the procyclicality of marginal cost considerably more than staggered price-setting does.  相似文献

This overview paper places in context eight papers coveringa wide spectrum of views on modern business cycle modelling.Inter alia, these address some gaps in the real business cycle(RBC) literature (e.g. the extremely limited treatment of creditand asset markets) and various other anomalies (e.g. the failureto explain volatility and persistence of employment and unemployment,and the non-cyclicality of real wages). The paper then focusesfurther on two issues central to RBC models. Such models aredriven by large and persistent technology shocks. However, empiricalevidence from UK manufacturing shows that correcting for cyclicalutilization results in shocks which are small and non-persistent.The second issue is one of empirical methodology. Though theRBC approach was intended as a response to the Lucas critique,by largely assuming away government policy feedback rules, thesemodels are far from policy-relevant. The alternative vectorautoregression (VAR) approach implicitly incorporates theserules, but ignores shifts in rules. A constructive responseto the Lucas critique needs to incorporate policy rule shiftsand private-sector reactions directly, which looks hard to achieveoutside the context of structural econometric modelling.  相似文献

We evaluate whether shocks to “animal spirits” affect real outcomes at business cycle frequencies, using data on consumer confidence and region- and state-level coincident activity indexes in a vector autoregression (VAR) with long run restrictions. We assume that animal spirits shocks do not affect the long run level of activity. Innovations in fundamentals explain most variation in the level of activity, but animal spirits have economically significant effects at business cycle frequencies. A positive innovation in animal spirits causes real activity to rise by between 0.2 and 0.6% in the medium term, and animal spirits may explain up to about half of real fluctuations in the medium run.  相似文献

This paper develops and estimates a dynamic optimizing model of the current account. The model focuses on real factors that determine the evolution of saving and investment and hence the external balance. Three types of shocks are at the center of the analysis: productivity shocks, shocks to labor input, and tax policy shocks. While our approach is in line with the real business cycle models of the current account, the distinguishing feature of the work is the application of econometric methods to time series data for a small open economy so as to directly estimate the parameters governing saving and investment under rational expectations restrictions.  相似文献

In this paper we study how firms react to demand shocks, examininghow different aspects of flexibility shape their responses.Our main findings are: (i) very few firms choose to adjust pricein response to a demand shock; (ii) firms with more flexibilityare more likely to respond to demand shocks by adjusting employmentand hours. Our results provide a microeconomic explanation forrecent macroeconomic evidence that labour input has become moreclosely aligned to the business cycle.  相似文献

This paper assesses the costs of forming a monetary union among the Gulf Cooperation Council (GCC) countries by looking at economic linkages within the GCC, and between the GCC and the potential anchors (the US, and major European countries such as France, Germany and Italy) for their proposed new currency. We investigate the importance of the US dollar compared to the Euro by focusing on aggregate demand (AD) and aggregate supply (AS) shock symmetry across these countries. We differentiated between oil and non-oil sector by estimating structural vector autoregression (SVAR) models with a combination of variables: oil output, non-oil output, total output, nominal/real price of oil and overall price level. One set of models was identified with the long-run restrictions of Blanchard and Quah (Am Econ Rev 79(4):655–673, 1989), whereas the set that assesses the robustness of the findings was estimated with the short-run restrictions of Sims (Eur Econ Rev 36(5):975–1000, 1992). We find overwhelming support for AD shock symmetry across the GCC countries and between the GCC and the US, but none for the major European countries with the GCC. Non-oil AS shocks are mostly asymmetric, but oil AS shocks are mostly symmetric when the real price of oil is included. This agrees with the view that GCC countries are subjected to common oil shocks. It also suggests that previous VAR models estimated to pass judgment on the feasibility of monetary union across GCC countries may have suffered from problems of mis-specification if the real price of oil was not considered. We surmise that the US dollar is a better anchor candidate for anchoring the new GCC currency than the Euro, since US monetary policy can at least help smooth demand shocks in these countries.  相似文献

Over a sample of nineteen industrial countries, more variable aggregate demand and/or higher mean inflation attenuates (augments) the effect of aggregate demand shocks on real output growth (wage and price inflation) while having no effect on the response of the real wage to such shocks. In all countries examined, aggregate demand shocks are positively (negatively) correlated with nominal variables (real output). Among explanations of the business cycle based on shocks to aggregate demand, this evidence favors the new Keynesian sticky wage explanation over the sticky price and the new classical imperfect information explanations.  相似文献

The Role of the Exchange Rate as a Shock Absorber in a Small Open Economy   总被引:2,自引:0,他引:2  
This paper analyses interactions between the real exchange rate and business cycles in a small open economy like Norway. Using a structural vector autoregression model, the role of different shocks are analysed, to investigate to what extent the real exchange rate is absorbing shocks, or a source of shocks itself. The results are ambiguous. Output and the real exchange rate are mainly explained by separate shocks, so that relinquishing exchange rate independence should come at little cost. However, the importance of nominal shocks in the business cycle emphasises that stabilisation is possible. Hence, remaining monetary independence may be attractive.  相似文献

In order to investigate the impacts of technology shocks on the recent Japanese business cycles, we construct an aggregate technological measure from industry-based data. Our approach is to estimate production function by industry, by controlling for the returns to scale factor and unobserved factor utilization. We find that positive technology shocks result in a contraction of labor input on impact. This result implies that the standard real business cycle (RBC) model is not supported and the new Keynesian model or the labor reallocation model is a candidate to explain the Japanese business cycles. From further empirical studies, we find that the labor reallocation model is plausible for explaining the Japanese business cycles.  相似文献

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.  相似文献

In the conventional Keynesian model, nominal wage contracts (acting as a friction) transmit monetary shocks to real variables. In contrast, the new classical or real business cycle theory claims that firms and workers ignore the behavior of the actual real wage and instead generate an efficient level of employment (hence, output) based on a shadow real wage. Using Brazilian data covering a period during which the economy suffered hyperinflation and wage contracts were indexed by the government, results show that these fixed nominal wage contracts did not generate a nonneutrality of money as proposed by the Keynesian model. Instead, results support the view that contracts cannot propagate nominal shocks.  相似文献

Standard dynamic small open economy models have predicted a counterfactual perfectly positive correlation between output and hours worked over the business cycle. In addition, this class of models exhibits a weak internal propagation mechanism. To address these anomalies, this paper incorporates intertemporally non‐separable labor supply and variable capital utilization into the canonical Mendoza (1991) model with adjustment costs of net investment. Our analysis shows that a dynamic, technology shock–driven small open economy model with internal habit formation in labor hours and endogenous capital utilization is able to account for the main real business cycle regularities of Canada after 1981.  相似文献

This paper analyzes the drivers of cross-border bank lending to 49 Emerging Markets (EMs) during the period 1990Q1–2014Q4, by assessing the impact of monetary, financial and real sector shocks in both the US and the euro area. The literature has traditionally highlighted the influence of US monetary policy on driving cross-border bank flows, and more recently the importance of both US and Euro Area (EA) financial/banking sectors’ related variables. Our contribution is the simultaneous analysis of the role of these US and EA drivers, as well as their interactions with real sector shocks. We corroborate the negative impact of US monetary policy tightening on cross-border lending to EMs, but we find that EA monetary policy seems to have an impact mostly on Emerging Europe, reflecting the fact that cross-border lending to most other EM regions is dollar denominated. We also find that real sector shocks in both the US and EA trigger an increase in cross-border lending, but less in EA when modeling the financial sector. Finally, for financial sector shocks, such as those associated with a decrease in bank leverage, our results indicate a broad-based overall contraction of cross-border lending if the shock originates in the US, and heterogenous effects across borrowing regions if the shock originates in the EA.  相似文献

This paper studies the trade balance dynamics in the G-7 countries plus Spain. We estimate a SVAR model to identify three different shocks: real supply shocks, real demand disturbances and nominal shocks. A microfounded stochastic open-economy model is built to derive the long-term identification restrictions. Estimates show that real demand shocks explain most of the variability of trade imbalances, whereas, contrary to previous findings, nominal shocks play a very limited role. These results are consistent with the predictions of a widely set of open-economy models and illustrate that demand policies are the main responsible of trade imbalances.  相似文献

Globalisation brought about worldwide changes, including economic and financial integration between countries. The objective of this paper is to establish if there is synchronisation between developed and developing countries with the world cycle. Research results show that business cycles have become less volatile after globalisation, but there is not much consensus on whether business cycles have become less or more synchronised since globalisation. Little research has been done on co‐movement between emerging markets, such as South Africa, and the world business cycle. This paper derives common factors for developed and developing countries by applying principal component analysis (PCA) to output, consumption and investment data, which represents the countries' business cycles. The empirical analysis shows co‐movement between some countries and the world business cycle (G7 countries as proxy). The results suggest that there are idiosyncratic and globally common shocks, which play different roles over time in different countries. The paper goes on to suggest that there are clear differences in how developed and emerging markets co‐move with the world business cycle. A key finding is that the co‐movement between developing economies and the world business cycle has increased since globalisation. This research also confirms previous research that most economies follow the world business cycle when large shocks – such as the recent economic downturn – occur. This has implications for forecasting the business cycle, especially in times of economic turmoil.  相似文献
