Macroeconomic shocks and stock market returns: the case of Korea

This study examines the effects of macroeconomic shocks on key macro variables, including stock market returns in Korea, using the structural vector autoregression (SVAR) model. We suggest a three-variable SVAR model incorporating inflation, output growth and stock returns. We adopt a nonzero z-ratio restriction for the long-run identifying assumption to allow for economically meaningful relationships among variables. While our results support the negative (positive) relation of demand (supply) shocks to stock returns, we also find that demand shocks influence stock market variance more significantly than supply shocks do. The sub-period analysis finds that global market fluctuations during the global financial crisis have relatively little effect on Korean stock market performance. We also examine a generalized five-variable model that includes the foreign exchange rate and interest rate, confirming the results from the three-variable case.     

Macroeconomic shocks under alternative exchange rate regimes: the Irish experience

The paper investigates the nature of Irish macroeconomic shocks and their correlation with German and UK shocks. A restricted VAR of real output and prices is employed to distinguish aggregate demand and supply shocks for the three countries. To identify the role of Irish exchange rate policy two periods are considered: the preERM period and the ERM period. The results indicate that while the change in exchange rate policy had an effect on the nature of demand and supply shocks, the ERM did not have the effect of increasing the correlation of Irish shocks with Germany or the UK. Evidence of substantial asymmetric shocks with Germany and the UK exist. Thus, Ireland as a member of the EMU faces increased cost of adjustment to asymmetric macroeconomic shocks.     

Macroeconomic and financial effects of oil price shocks: Evidence for the euro area

The paper investigates the macroeconomic and financial effects of oil price shocks for the euro area, with a special focus on post-2009 oil price dynamics and the recent slump. The analysis is carried out episode by episode, by means of a large-scale time-varying parameter model. We find that recessionary effects are triggered by oil price hikes and, in some cases, also by oil price slumps. In this respect, the post-2009 run-up likely contributed to sluggish growth, while uncertainty and real interest rate effects are the potential channels through which the 2014 slump has depressed aggregate demand and worsened financial conditions. Also in light of the zero interest rate policy carried out by the ECB, in so far as the Quantitative Easing policy failed to generate inflationary expectations, a more expansionary fiscal policy might be required to counteract the deflationary and recessionary threat within the expected environment of soft oil prices.     

Macroeconomic policy uncertainty shocks on the Chinese economy: a GVAR analysis

This article studies the spillovers of economic policy uncertainty (EPU) from developed economies to China in terms of the source, extent and persistence by estimating a global vector autoregressive (GVAR) model with both financial and trade variables acting as the transmission channels. Our findings confirm the existence of international transmissions of policy uncertainty, while the patterns differ markedly. The US EPU appears to be the most significant cause of the fall of export, industrial production, equity price and exchange rate, meanwhile, the EU EPU is also to be blamed for the depreciation of RMB. In contrast to industrial production, which shows the largest negative impact, Chinese inflation increases to a relatively smaller extent with the EPU shocks ranking as the US, Japanese and the EU. Regardless of the minor impact on a long-term interest rate, the short-term interest rate in China reacts positively to the European and US EPU shocks. Despite the independent national monetary policies, EPUs from the EU, Japan and the UK can decrease the Chinese monetary aggregate. In summary, the Chinese economy responds the most to the US EPU, especially to its inflation expectation disagreement component, whereas it responds the least to the UK EPU.     

Macroeconomic impacts of fiscal policy shocks in the UK: A DSGE analysis

This paper develops and estimates a new-Keynesian dynamic stochastic general equilibrium (DSGE) model for the analysis of fiscal policy in the UK. We find that government consumption and investment yield the highest GDP multipliers in the short-run, whereas capital income tax and public investment have dominating effect on GDP in the long-run. When nominal interest rate is at the zero lower bound, consumption taxes and public consumption and investment are found to be the most effective fiscal instruments throughout the analysed horizon, and capital and labour income taxes are established to be the least effective. The paper also shows that the effectiveness of fiscal policy decreases in a small open-economy scenario and that nominal rigidities improve effectiveness of public spending and consumption taxes, whereas decrease that of income taxes.     

Macroeconomic effects of government spending shocks: New narrative evidence from Canada

This paper examines the macroeconomic effects of government spending shocks in Canada for the period of 1949–2012. We construct a novel measure of news about exogenous government spending changes identified through the narrative approach. We use government documents, mostly the budget speech, to identify the size, timing, and principal motivation for all planned major federal government spending changes. To achieve identification, we consider those changes that are unrelated to the contemporaneous movements in the economy. The implied government spending multiplier estimates using our exogenous government spending news series are between 1.08 and 1.69.     

Macroeconomic volatility and anti-refugee violence in developing countries: Evidence from commodity price shocks

I investigate the effect of macroeconomic (output) volatility on anti-refugee violence in developing countries. Opportunity cost, rapacity, and state capacity theories predict ambiguous effects. For causal inference I leverage output volatility caused by plausibly exogenous commodity price shocks. I find that adverse commodity price shocks increase both violence of natives against refugees and violence between refugees. My results suggest that anti-refugee violence increases during recessions and decreases during economic booms.     

Demand shocks,supply shocks and the cyclicality of real wages

The behaviour of real wages over the business cycle has received increasiing attention in recent years. The cyclicality of real wages constitues an important aspect of recent models of the business cycle. However,empirical studies undertaken to determine whether real wages are procyclical or countercyclical have reported conflicting findings. In thiis paper we use vector-autoregressions to analyse the cyclicality of real wages. We find that the source of the disturbance plays a decisive role in the cyclical behaviour of real wages. In particular, we demonstrate that a supply shock generates procyclical real wages,whereas a demand shock yields countercyclicality.     

The contemporaneous correlation between price shocks and output shocks

Until the 1990s, prices were believed to be procyclical. Several researchers have since presented evidence of counter-cyclical prices. This evidence proved robust, but its interpretation has varied. Some have argued that the contemporaneous correlation between output and prices reflects both the source of the current shock and the adjustment process from short-run to long-run equilibrium; the adjustment to the long run imparts a bias towards a negative price-output correlation. The issue of dynamics is addressed by estimating price shocks and output shocks. The sign of the correlation between these shocks does not reveal anything about the relative importance or frequency of demand versus supply shocks; however, some understanding is gained from the time-series of the product of the shocks. In periods when the product is negative, supply shocks must have been either relatively large or relatively important. In periods when the product is positive, demand shocks must have been either relatively large or relatively important. The data suggest that the economies of the USA, Canada and the UK were buffeted by both demand and supply shocks in about equal portions.     

宏观调控与实体经济

我国当前的宏观经济面临通货膨胀和经济增长下行的双重压力,两者都会在实体经济上反映出来。针对通货膨胀应该高度关注并采取适度的宏观调控政策,但不能反应过度。现阶段的主要矛盾已经转到经济增长下行问题。宏观经济学的精髓在于均衡,合适的宏观政策应该是在保持经济增长和控制通货膨胀之间找到均衡,选择一个合适的均衡点。我国近期根据宏观经济的走势实施稳健的货币政策和积极的财政政策,意味着将会释放出数量较大的流动性,而这些流动性应该重点流向实体经济。有效的宏观调控必须是以市场化改革所形成的经济体制为基础的。不能因为宏观调控而放慢市场化改革的步伐,尤其要支持实体经济领域民营经济的发展。     

Macroeconomic Consequences of the EMU

European Monetary Union was sold to the German public on the claim that the common currency would make the European economy stronger and that this would yield significant welfare gains. Such claims are commonly based on three propositions. (1) The common currency will be a strong international currency and the real appreciation of the euro against other currencies will make the EMU citizens richer. (2) The common currency will change labor market relations and increase labor market flexibility, and this will reduce the high rate of structural unemployment in Europe. (3) The common currency will create competition among the governments in the dimension of regulatory and tax policies and induce governments to undertake structural reforms which are long overdue, and this will set the EMU economy on a higher growth path.In this paper we discuss these three claims. We agree with the basic ideas of each of them. But the suggested result of a stronger EMU economy remains questionable. The euro may lead to more or to less labor market inflexibility, and competition among governments in the EMU has a high and a low-regulation equilibrium. Where the euro takes the European economy depends largely on the political willingness to engage in reforms.     

Macroeconomic fluctuations and bargaining

I study the limit rule for bilateral bargaining when agents recognize that the aggregate economy (and thus the match surplus) follows a finite-state Poisson process. The rule derived in this paper is of special importance for decentralized exchange economies with bargaining. Two simple applications are presented to illustrate this fact. The first example is a model of wage bargaining and trade externalities. I show that in such situations sophisticated bargaining tends to increase the volatility of the wage bill. The second example is based on the Kiyotaki-Wright model of money. I explain how equilibrium prices depend in a fundamental way on the dynamic bargaining solution.     

Using Romer and Romer's new measure of monetary policy shocks to identify the AD and AS shocks

This article re-examines the series of (exogenous) Federal Funds Rate (FFR) shocks created by Romer and Romer (2004) for the period 1969:01–1996:12. We hypothesize that if Romer and Romer have constructed a reasonable set of monetary policy shocks, then including them in a small Vector Autoregression (VAR) should help to identify other structural shocks that affected the United States economy during their sample period. Using a sample period of 1971:01–1996:12 we are easily able to identify both an Aggregate Demand (AD) shock and an Aggregate Supply (AS) shock without imposing any sign or long-run restrictions. We present historical decompositions that allow us to compare the relative importance of these shocks with that of the exogenous monetary policy shocks in explaining output fluctuations during the 1973–1975, 1980–1984 and 1990–1991 business cycle episodes.     

Financial shocks and worry about the future

Using data from the Health and Retirement Study and the Survey of Consumer Finances, we show that households that experience adverse financial shocks worry more about the adequacy of their financial resources in retirement, even after controlling for the effects of these shocks on overall wealth. We find supporting evidence that suggests that at least part of the increased worry about retirement is due to general pessimism rather than changes in an individual’s own circumstances. Specifically, experiencing idiosyncratic financial shocks is also associated with greater pessimism about the general future of the economy.      

Macroeconomic Theorizing and the Instability of Post-Keynesian Capitalism

Financial innovations are associated with market crises. Hyman Minsky singles out financial innovations as particularly prone to instability so as to necessitate governmental intervention. Processes of innovation and diffusion in new products and in new financial instruments have commonalities as well as differences. This paper focuses on the differences with a view to better understand why financial innovations are more likely to generate significant negative repercussions. Differences that distinguish financial innovations include the role of intermediaries, variability in quality, and the extent of externalities. This paper further discusses the implications of these differences.     

Technology shocks around the world

This article investigates the effects of a permanent technology shock on labor input in the major seven developed countries. The recent empirical literature which uses Structural Vector Autoregressions (SVAR) with long-run restrictions has argued that technology shocks lead to a persistent and significant decline in employment in most of the G7 countries. We claim that the international transmission of shocks prevents the use of existing SVAR models, but also suggests alternative specifications to properly uncover their effects. We show in a quantitative two-country model that a measure of labor productivity aggregated across countries is more immune to persistent, if not permanent, shocks and allows to accurately identify the responses of the labor input to a technology shock. Using labor productivity at the G7 aggregate level, we find that the response of employment changes critically in most of the major seven developed countries.     

Understanding the effects of technology shocks

The research led by Gali (AER 1999) and Basu et al. (AER 2006) raises two important questions regarding the validity of the RBC theory: (i) How important are technology shocks in explaining the business cycle? (ii) Do impulse responses to technology shocks found in the data reject the assumption of flexible prices? Using an RBC model, this paper argues that the conditional impulse responses of the U.S. economy to technology shocks are not grounds to reject the notion that technology shocks are the main driving force of the business cycle and the assumption of flexible prices, in contrast with the conclusions reached by the literature.     

Monetary policy and the transmission of oil shocks

This paper provides evidence on the role played by monetary policy in the transmission of oil shocks to the US economy. We show that for the period since 1986, oil shocks have had a negative effect on stock returns, regardless of whether the oil shock is defined as the percentage change in the price of oil or a nonlinear transformation of that series. We then demonstrate that there is no relationship between the reaction of individual stock prices to oil shocks and to monetary policy shocks. This implies that oil shocks do have effects on the economy beyond their effect on monetary policy. We conclude that systematic monetary policy is not as effective as suggested in some previous studies.
