Uncertainty shocks and asymmetric dynamics in Korea: a non-linear approach

This study investigates the impact of uncertainty shocks on macroeconomic activity in Korea. For this purpose, a Smooth Transition VAR model is employed to document the state-dependent dynamics of two distinct types of uncertainty shocks, namely, financial market based and news-based. When non-linearity is allowed to play a role in our model, quantitatively very different asymmetric dynamics are observed. Following inflation targeting, the responses tend to be smoother and less pronounced. Our empirical results support the view that the link between uncertainty and macroeconomic activity is clear over both recessions and expansions. Furthermore, the impact of uncertainty shocks is more pronounced when economic activity is depressed especially after shocks originate from the financial market, and not from news-based policy uncertainty in Korea.     

Forecasting growth during the Great Recession: is financial volatility the missing ingredient?

The Great Recession endured by the main industrialized countries during the period 2008–2009, in the wake of the financial and banking crisis, has pointed out the major role of the financial sector on macroeconomic fluctuations. In this respect, many researchers have started to reconsider the linkages between financial and macroeconomic areas. In this paper, we evaluate the leading role of the daily volatility of two major financial variables, namely commodity and stock prices, in their ability to anticipate the output growth. For this purpose, we propose an extended MIDAS model that allows the forecasting of the quarterly output growth rate using exogenous variables sampled at various higher frequencies. Empirical results on three industrialized countries (US, France, and UK) show that mixing daily financial volatilities and monthly industrial production is useful at the time of predicting gross domestic product growth over the Great Recession period.     

金融危机的货币政策反应

自20世纪90年代以来,我国已经历两次由国际金融危机所引发的宏观经济紧缩,这表明外源性冲击已成为影响国内经济增长的重要制约因素.实证研究表明,在当前国内经济受到外部冲击而出现紧缩时,货币政策对消费和投资的影响依然显著,但在效果上存在差异.降低利率能长期稳定提高消费增长;而货币供应量扩张仅在五个季度内能显著刺激投资增长,长期基本无效.因此,本文认为现阶段在与财政政策和产业政策配合拉动内需时,应将带动国内消费增长作为货币政策长期任务,而将提高国内投资作为短期目标.     

Employment and output effects of financial shocks

This paper develops a New Keynesian model featured with financial frictions in the form of an exogenous credit constraint to explore the employment and output effects of financial shocks. I show that the equity payout adjustment costs are crucial for the transmission mechanism of financial shocks. The model is estimated using the Bayesian methods and simulated using the observed exogenous shocks for two periods, 1954:III–1983:IV and 1984:I–2015:I. Overall, it is found that financial shocks can account for the observed dynamics of employment and output, especially the sharp decreases during the Great Recession 2007–2008. Additionally, the financial shock is the third and second biggest contributor to output and employment variations, respectively, in the earlier period, but it turns out to be the main source of employment and output fluctuations in the later period. I find that firms are faced higher equity payout adjustment costs in the period 1984:I–2015:I, which accounts for greater variations in the equity payouts in the period.     

金融加速器效应在中国存在吗?

本文从金融加速器理论出发,运用门限向量自回归(TVAR)模型在宏观层面上对中国信贷市场与宏观经济波动的非线性关联展开实证研究。通过非线性脉冲响应函数的检验结果我们发现:在1990年1月至2006年5月期间,中国存在显著的金融加速器效应,表现为对于相同特征的各种外生冲击,经济波动在信贷市场处于"紧缩"状态下的反应均明显强于信贷市场处于"放松"状态下的反应。另外,信贷冲击对于信贷市场状态变化的作用最为显著,其次是货币冲击和价格冲击,最后是实际冲击。进一步的检验还表明:信贷市场在宏观经济波动过程中既是重要的波动源,同时也是波动的有力传导媒介,运用金融加速器理论有助于合理解释中国宏观经济波动的轨迹特征。最后本文阐述了实证结论的政策含义和未来研究的侧重点。     

It ain’t over till it’s over: A global perspective on the Great Moderation-Great Recession interconnection

A large-scale Factor-Augmented Vector Autoregressive (FAVAR) model of the global economy is used to investigate the determinants of the Great Moderation and the transition to the Great Recession (1986–2010). Beside the global-economy perspective, the model presents the novel feature of a broad range of included financial variables and risk factor measures. The results point to various mechanisms related to the global monetary policy stance (Great Deviation), financial institutions’ risk-taking behaviour (Great Leveraging) and global imbalances (savings glut), determining aggregate fluctuations. Finally, an out-of-sample forecasting exercise provides evidence against the ‘end of the Great Moderation’ view, showing that the timing, though not the dimension of the Great Recession episode (2008–2010), was predictable on the basis of the same macroeconomic mechanisms at work over the two previous decades.     

The Great Recession,Household Income,and Children's Test Scores

Economic downturns may have important implications for the educational attainment and human capital accumulation of children. We examine how income losses during the Great Recession were associated with children's educational performance in Ireland, one of the countries most severely affected by the global financial crisis. Using longitudinal data from a nationally representative child cohort study, collected before and after the recession at ages 9 and 13 years, we estimate panel models to examine the impact of income changes on standardized tests. We explore both objective and subjective measures of recession impact, and investigate non-linearities and effect heterogeneity using quantile regression. While income is strongly associated with educational performance overall, there is little evidence of a short-run negative impact of income shocks during the Great Recession on children's test scores.     

Unemployment dynamics in emerging countries: Monetary policy and external shocks

This paper quantifies the impact of three key external shocks – external demand, interest rate, and uncertainty shocks – on emerging market economies (EMEs). We find that external shocks have a sizeable impact on macroeconomic fluctuations in EMEs and that a considerable fraction of this impact is through the domestic stock market. A decrease in external demand and an increase in external interest rate and uncertainty lead to a higher unemployment rate, lower stock market return, and a depreciation of the domestic currency. The EMEs' monetary policy actively responds to external shocks and dampens their impact on domestic activity.     

Hayek, Keynes, and modern macroeconomics

The Great Recession seems to be creating a change in the trend of macroeconomic thinking. Prior to the financial crisis of 2008, dynamic stochastic general equilibrium (DSGE) models dominated the macroeconomics literature without any apparent challengers on the horizon. Since then, however, we have seen an increasing interest in macroeconomic models that address the state of confidence (??animal spirits??), complexity, cognition, and radical uncertainty. Most of the renewed interest in animal spirits, complexity, cognition, and radical uncertainty has come from a more or less ??Keynesian?? perspective. We discuss the potential to emphasize these elements from a more ??Hayekian?? perspective and argue that Austrian approaches to macroeconomics along these lines are more likely to resonate with mainstream economists than in years past.     

Macroeconomic Uncertainty,Fund Demand and Corporate Investment

Using a unique set of data on fund use by China’s listed companies, this paper examines how macroeconomic uncertainty works on corporate investment. The study shows that macroeconomic uncertainty affects corporate investment behavior through the three channels of external demand, liquidity demand and long-term fund demand. However, the result is influenced by expectations and can differ across firms depending on their economic cycle, shareholder character, industrial character and the financial constraints they are exposed to. Specifically, high macroeconomic uncertainty can weaken the positive roles of these channels, especially those of external demand and liquidity demand, in driving corporate investment. During economic upturns, the effect of these channels is the most evident among state-owned firms, manufacturing firms and low cash dividend firms. The lessons from this study are that macroeconomic policies should be leveraged taking account of the channels through which economic shocks find their way, and monetary policies have to be implemented by targeting microscopic fund demand.     

Asymmetric effects of uncertainty shocks: Normal times and financial disruptions are different

We examine whether the response of the euro area economy to uncertainty shocks depends on financial conditions. We find strong evidence that uncertainty shocks have much more powerful effects on key macroeconomic variables in episodes marked by financial distress than in normal times. We also document that the recovery of economic activity following an adverse uncertainty shock is state dependent: it is gradual in normal times, but displays a more accelerated rebound when the shock hits during financial distress, reflecting monetary accommodation provided by the central bank. These findings are based on a non-linear data-driven model that accounts for regime switching and time-varying volatility. Our findings imply that whether financial markets are calm or distressed matters when it comes to the appropriate policy responses to uncertainty shocks.     

Economic uncertainty in South Africa

The idea that heightened uncertainty among firms contributed to the Great Recession and the lacklustre subsequent recovery has inspired a substantial literature examining the impact of changes in uncertainty on output and investment decisions. Yet to date there has been little research on business uncertainty in emerging markets. This paper is one of the first to develop a set of survey-based proxies for business uncertainty for an emerging market, South Africa, based on micro-data from business tendency surveys. These survey-based proxies are combined with more common measures of uncertainty, based on financial data and text mining, to obtain a composite measure of economic uncertainty. The paper then examines whether the uncertainty indicators have plausible and significant relationships with real economic activity, even after controlling for other economic variables. The indicators exhibit a significant negative correlation with real GDP growth, consistent with the findings for developed countries, and a positive shock to uncertainty is generally followed by a significant decrease in real activity growth.     

BUSINESS FAILURES AND MACROECONOMIC FACTORS IN THE UK

We examine the interactions between business failures and macroeconomic aggregates, and specifically the accounts of policy-induced changes in the macroeconomy for the observed fluctuations of UK business failures in the period 1966–2003 using the vector error-correction model (VECM). The results demonstrate that macroeconomic aggregates, i.e., interest rate, credit, profits, inflation and business births, exert differential impacts on business failures both in the short run and in the long run. The study reveals that structural changes in the financial and real sectors during the examined period have made an impact on the way in which the macroeconomy affects business failures. In particular, business failures are increasingly reacting to monetary policy changes in the post-1980 period. Furthermore, the shocks to business failures can generate large fluctuations in macroeconomic aggregates, suggesting the importance of corporate balance sheets in financial stability and economic growth. The paper's findings carry policy implications that are related to the survival of firms in distress and finance-driven business cycles.     

MONETARY POLICY UNCERTAINTY AND ECONOMIC FLUCTUATIONS

We investigate the relationship between uncertainty about monetary policy and its transmission mechanism, and economic fluctuations. We propose a new term structure model where the second moments of macroeconomic variables and yields can have a first‐order effect on their dynamics. The data favor a model with two unspanned volatility factors that capture uncertainty about monetary policy and the term premium. Uncertainty contributes negatively to economic activity. Two dimensions of uncertainty react in opposite directions to a shock to the real economy, and the response of inflation to uncertainty shocks varies across different historical episodes.     

Fiscal Multiplier in Microstates: Evidence from the Caribbean

The global financial crisis and the attendant Great Recession of 2007–2009 have spawned a full-scale re-examination on the effectiveness of fiscal policy throughout the world. While this has led to a plethora of analyses in developed countries, the same abundance of the work has not been evident for developing counties. This paper uses time-series analysis to examine the multiplier impact of fiscal policy on growth and other macroeconomic variables in the case of four Caribbean states. Although these countries have similar degrees of openness, they differ in debt burdens and economic structures, thus providing a natural laboratory for this investigation. We concluded that fiscal multipliers among the sample countries are quite low and that the contemporaneous fiscal stance appears to be pro-cyclical.     

International Integration,Trade, and the Great Recession

In the wake of the Great Recession, almost all countries suffered a severe and synchronized trade collapse unlike any seen since the Great Depression. To the extent that economic integration fosters trade among countries, this paper examines the role that international integration played in moderating the negative shock caused by the Great Recession on trade. The methodology adopted is a modified gravity model in which we control for the Great Recession, different forms of integration, as well as the interaction between integration and the recession. Measuring integration in three different ways, the findings show that countries that were more integrated fared better in trade – the extent of trade collapse was milder – than less integrated countries. Specifically, Regional Trade Agreement, as a form of trade integration, had a positive and robust effect on trade during the Great Recession. This positive effect is also robust across regions and countries around the world. In a nutshell, countries that are into some form of trade agreements are better-positioned to absorb negative demand-side shocks caused by economic recessions than similar countries without such agreements.     

ON THE SOURCES OF AGGREGATE FLUCTUATIONS IN EMERGING ECONOMIES

Recent research on macroeconomic fluctuations in emerging economies has advocated introducing a stochastic productivity trend or allowing for interest rate shocks and financial frictions. We estimate a model that encompasses these two approaches, shedding light on their relative merits and on how financial frictions affect the transmission of shocks. The model accounts for aggregate fluctuations by assigning a dominant role to financial frictions in amplifying conventional (temporary) productivity shocks, whereas trend shocks play a minor role. A link between spreads and expected future productivity emerges as essential for a reasonable approximation to the data.     

Is the relationship between gold and the U.S. dollar always negative? The role of macroeconomic uncertainty

The main work of this article is to access the role of macroeconomic uncertainty in effecting the correlation between gold and the dollar. The empirical analysis is divided into two parts. Firstly, we examine the impact of macroeconomic uncertainty on short and long correlation between gold and the dollar. Secondly, we analyse the explanatory power of economic uncertainty for the abnormal market relation between gold and the dollar with a threshold model. In particular, we investigate impacts of economic uncertainty sourced from different economies. The empirical results indicate that economic uncertainty generates direct impacts on the correlation between gold and the dollar. Moreover, our results emphasize that uncertainty sourced from different economies have different impacts on the dynamics between gold and the dollar. This article also presents the relative contribution of gold and the dollar shocks to the likelihood of being in the high-uncertainty regime. These results have implications for risk management, international asset allocation and hedging strategies.     

WHAT DO VARS TELL US ABOUT THE IMPACT OF A CREDIT SUPPLY SHOCK?

In the aftermath of the recent financial crisis, a variety of structural vector autoregression (VAR) models have been proposed to identify credit supply shocks. Using a Monte Carlo experiment, we show that the performance of these models can vary substantially, with some identification schemes producing particularly misleading results. When applied to U.S. data, the estimates from the best performing VAR models indicate, on average, that credit supply shocks that raise spreads by 10 basis points reduce GDP growth and inflation by 1% after one year. These shocks were important during the Great Recession, accounting for about half the decline in GDP growth.     

油价冲击、货币政策调整与产出波动——基于中国的经验证据

本文基于我国2001-2010年宏观经济月度数据,采用SVAR模型分析了国际油价波动时,央行货币政策在排除回应油价干扰与未排除干扰下的反应差异及油价波动对产出的影响。研究发现,在排除货币政策回应油价波动干扰后,通过脉冲响应函数反映的油价波动对产出的短期负面影响消失。方差分解结果显示,长期内产出波动由油价冲击和货币政策解释的比例分别为5716%和32480%,比排除干扰前分别下降了2569%和4560%。这说明我国油价冲击带来的经济衰退主要是因为货币政策及其回应油价冲击紧缩所致。此外,面对油价的短期冲击,CPI指数并未随着生产者购进价格指数上升而上升,产出也未发生明显的衰减;但在较长时间内,油价上升会因为相对价格的改变,而影响CPI水平和货币政策,从而对产出产生显著的负面影响。
