Policy Uncertainty and the Demand for Money in Korea: An Asymmetry Analysis

Previous studies included money supply volatility as well as output volatility as measures of uncertainty in estimating the demand for money. However, a more comprehensive measure of uncertainty is now constructed for many countries and is known as policy uncertainty. When we included this new measure in the formulation of the demand for money in Korea and relied upon a nonlinear specification of the money demand which allows us to assess the asymmetric effects of changes in the policy uncertainty measure, we found asymmetric long-run effects of policy uncertainty on the demand for cash in Korea. Our conjecture is that increased uncertainty induces Koreans to hold less cash in favor of safer assets and decreased uncertainty has opposite effects, though at different rate.     

相机抉择政策、经济增长与地区产出波动

本文旨在研究地方政府的相机抉择政策对经济增长和产出波动的实际影响。本文首先从预算软约束和晋升激励的角度分析这一政策的作用方式，然后用模型测度出相机抉择政策，并以2000—2013年的省际面板数据进行实证检验。研究表明，相机抉择的确刺激了地方经济增长，但却带来了明显的产出波动。不过相机抉择政策具有明显的时滞，其真实效果集中凸显在政策实施的两年后。因此，我国应加强公共财政制度的建设，使相机抉择政策在规则的框架下更为合理地使用。     

The macroeconomic effects of fiscal rules in the US states

Fiscal policy restrictions are often criticized for limiting the ability of governments to react to business cycle fluctuations and, consequently, the adoption of quantitative restrictions is viewed as inevitably leading to increased macroeconomic volatility. In this paper, we use data from 48 US states to investigate how budget rules affect fiscal policy outcomes. Our key findings are that (1) strict budgetary restrictions lead to lower policy volatility (i.e. less aggressive use of discretion in conducting fiscal policy) and (2) fiscal restrictions reduce the responsiveness of fiscal policy to output shocks. These two results should have opposite effects on output volatility. While less discretion should reduce volatility, less responsiveness of fiscal policy might amplify business cycles. We provide empirical support for the first effect: restrictions, by reducing discretion in fiscal policy, can reduce macroeconomic volatility.     

Uncertainty and the macroeconomy: evidence from an uncertainty composite indicator

This article proposes a uncertainty composite indicator (UCI) based on three distinct sources of uncertainty (namely financial, political, and macroeconomic) for the US economy on the period 1985–2015. For that, we use a dynamic factor model, summarizing efficiently six individual uncertainty proxies, namely two macroeconomic and financial uncertainty factors based on the unpredictability, a measure of (micro)economic uncertainty, the implied volatility index, the corporate bond spreads, and an index of economic policy uncertainty. We then compare the effects of uncertainty on economic activity when the UCI is used instead of individual uncertainty proxies in structural VAR models. The interest of our UCI is to synthesize theses effects within one measure of uncertainty. Overall, the UCI was able to account for the most important dynamics of uncertainty which play an important role in business cycles.     

Economic policy uncertainty and the Chinese stock market volatility: Novel evidence

In this study, we investigate the impact of global economic policy uncertainty (GEPU) on Chinese stock market volatility. More importantly, for the first time, we explore the effects of directional GEPU based on the changing directions of GEPU and Chinese economic policy uncertainty (EPU). We make several noteworthy findings. First, the in-sample estimated results show that up and down GEPU can lead to substantially high stock market volatility for China. Second, the out-of-sample estimated results support the contention that the GEPU index is helpful for predicting volatility. Moreover, compared to GEPU alone, directional GEPU can provide more useful information that can increase the forecast accuracy. Third, we empirically find that directional GEPU is more effective in predicting Chinese stock market volatility when GEPU and EPU rise in the same month.     

Do the central bank actions reduce interest rate volatility?

This paper investigates how Central Bank of Brazil (CBB) actions influence market uncertainty. We consider two kinds of actions: the monetary policy decision about the interest rate target and the pure communication event of this decision published one week later. Unlike related papers, we measure the market uncertainty by the implied volatility extracted from interest rate options. Implied volatility is more suitable than physical volatility to assess economic effects since it encompass market beliefs adjusted by risk. We use an event study approach to evaluate the impact of CBB actions. The results show that both the decisions about the target rate and the communication event reduce the interest rate volatility.     

Social polarization, fiscal instability and growth

We present a dynamic model of fiscal policy in a simple growth framework where social polarization (of preferences) plays a central role in the evolution of fiscal instability and growth collapse. In a highly polarized society, a deficit occurs endogenously, fiscal spending path becomes more volatile, output collapses, and economic growth rate is reduced along the transition path to a new lower level of output. One novel feature is that the size of fiscal deficit, the magnitude of fiscal volatility, and the size of reduction in output and growth rate are explicitly shown to be increasing functions of the degree of social polarization. This is because of the positive relationship between the polarization of preferences and the incentive for policymakers (or socio-economic groups) to overexploit the government resources in a common pool setting (polarization effect). Thereby, we offer a fiscal instability channel that negatively links social polarization and growth, which is an alternative yet distinct explanation for the empirical finding that social polarization is harmful to growth. Moreover, we fully distinguish the incentive to engage in such short-term policies under political uncertainty from that under polarization. Polarization and political uncertainty are shown to be distinct yet critical to the dynamic coordination failure in the common pool setting.     

Economic Risk and Political Risk in Fiscal Unions

A fiscal programme that redistributes income from rich to poor individuals indirectly redistributes tax revenues from regions hit by a favourable shock to regions hit by an unfavourable one. Centralised fiscal redistribution has therefore been advocated as a way to insure individuals against region-specific shocks. In this paper, we argue that a centralised fiscal policy, while reducing the uncertainty on the tax base, may create additional uncertainty on the tax rate. Using a simple model we show that the higher uncertainty on the policy instrument might more than offset the lower uncertainty on the tax base.     

预期到的与未预期到的财政政策冲击及其宏观影响*

本文根据1999-2014年中国宏观经济季度数据,在动态随机一般均衡模型框架下,考察了预期到的与未预期到的财政政策的宏观经济效应及其传导机制。本文研究发现：第一,预期到的与未预期到的财政政策均具有显著的宏观经济效应,二者合起来可以解释3634%的产出波动、1424%的就业波动和618%的物价波动;第二,与未预期到的财政政策直接影响经济均衡系统不同,预期到的财政政策主要是通过影响经济主体关于未来经济状态的信念来改变经济的均衡配置;第三,财政政策的宏观经济效应不仅取决于所选取的政策类型,而且受公众预期的影响。因此,政府不仅应当根据宏观经济目标理性选择财政政策工具,而且需要合理引导公众预期,以增强财政政策的针对性和有效性。     

Political,Institutional, and Economic Factors Underlying Deficit Volatility

It is well known that fiscal policy can counter‐cyclically smooth out the effect of unexpected shocks and public deficit volatility may reflect the (optimal) policy response to them. However, the welfare losses associated to fiscal instability are also an important challenge for many countries, as it typically implies an inefficient allocation of resources, higher sovereign risk premium and an inadequate provision of public services. In this paper, we empirically analyze the political, institutional, and economic sources of public deficit volatility. Using the system‐generalized method‐of‐moments (GMM) estimator for linear dynamic panel data models and a sample of 125 countries analyzed from 1980 to 2006, we show that higher public deficit volatility is typically associated with higher levels of political instability and less democracy. In addition, public deficit volatility tends to be magnified for small countries, in the outcome of hyper‐inflation episodes and for countries with a high degree of openness.     

Fiscal institutions and public spending volatility in Europe

This work provides empirical evidence for a sizeable, statistically significant negative impact of the quality of fiscal institutions on public spending volatility for a panel of 23 EU countries over the 1980–2007 period. The dependent variable is the volatility of discretionary fiscal policy, which does not represent reactions to changes in economic conditions. Our baseline results thus give support to the strengthening of institutions to deal with excessive levels of discretion volatility, as more checks and balances make it harder for governments to change fiscal policy for reasons unrelated to the current state of the economy. Our results also show that bigger countries and bigger governments have less public spending volatility. In contrast to previous studies, the political factors do not seem to play a role, with the exception of the Herfindahl index, which suggests that a high concentration of parliamentary seats in a few parties would increase public spending volatility.     

Price stabilizing, Pareto improving policies

One possible justification for a stabilization policy is that there is volatility in macro variables that individual agents cannot insure against. We study the simplest possible extension of the stochastic two-period, one agent and one commodity OLG model, where we have added one more period, with only one potential activity, namely, trading of contingent commodities. We assume, however, that markets are incomplete. In this case the Monetary equilibrium is not Pareto Optimal and for an open set of economies an allocation where fluctuations in realized savings are removed, Pareto dominates the monetary equilibrium. This allocation may be implemented by means of a monetary/fiscal policy. The policy considered has a simple rationale, namely that it removes some of the uncertainty that agents face by reducing price, i.e interest rate volatility. We consider two fundamental sources of such volatility, namely, respectively an objective and a subjective signal about the distribution of future endowments. The first case is when agents have rational expectations while the second case is studied in the context of agents having rational beliefs, beliefs which are consistent with empirical observations but not (necessarily) correct.     

The macroeconomic effects of fiscal policy in a stochastically growing economy

This paper develops a stochastic model of endogenous growth with productive government expenditure. Herein, we specify the CES production function according to recent empirical evidence. The elasticity of substitution plays a key role in determining macroeconomic performance and the effectiveness of fiscal policy under uncertainty. Results demonstrate that a large elasticity of substitution provides a large expected growth rate and also large volatility of the growth rate. Regarding these effects, the growth-maximizing tax rate and welfare-maximizing tax rate under uncertainty are larger or smaller than those of deterministic economy according to the elasticity of substitution.     

Macroeconomic Policy and Employment Growth in Australia

Abstract
This article, which explores various aspects of macroeconomic policy and employment growth, is prompted by the relative lack of attention given to these issues in the Green and White Papers on unemployment. The problem of hysteresis reinforces the generally recognised need to reduce the excessive volatility of output and employment growth in Australia. International comparisons presented in the article suggest that Australian output and employment growth have been more volatile than those of the three major OECD countries. Reduction in macroeconomic volatility requires more effective short-term demand management than we have had in the recent past, and in turn, means that we must know more about the strength and timing of the effects of major macroeconomic policy instruments on employment growth and unemployment. This article presents employment growth equations for Australia over the period 1979–93 which incorporate domestic macroeconomic policy effects as well as the influences of the international business cycle. We show that monetary and fiscal policy have had a significant impact on the evolution of employment in Australia and, in particular, that tight monetary and fiscal policy contributed substantially to the recession of 1990–92.     

Macroeconomic Stabilization in the EMU: Rules Versus Institutions

This paper investigates the macroeconomic implications of different regimes of international fiscal coordination and monetary‐fiscal cooperation in a monetary union with independent fiscal authorities, that act strategically vis‐à‐vis a common central bank. In the presence of other policy goals than cyclical stabilization, such as interest rate smoothing and fiscal stability, we show that coordination among national fiscal authorities can reduce output and inflation volatility relative to the non‐cooperative setting in specific circumstances, as in case of demand disturbances, while turning potentially counterproductive otherwise. The adverse effects of union‐wide coordinated fiscal measures can be attenuated in a regime of global coordination, namely, when a centralized fiscal stabilization is coordinated with the common monetary policy as well.     

HOW DO FISCAL CONSOLIDATION AND FISCAL STIMULI IMPACT ON THE SYNCHRONIZATION OF BUSINESS CYCLES?

Using quarterly data for a panel of advanced economies, we show that synchronized fiscal consolidation (stimulus) programmes in different countries make their business cycles more closely linked. We also find: (i) some evidence of decoupling when an inflation targeting regime is unilaterally adopted; (ii) an increase in business cycle synchronization when countries fix their exchange rates and become members of a monetary union; (iii) a positive effect of bilateral trade on the synchronization of business cycles. Global factors, such as a rise in global risk aversion and uncertainty and a reversal of nonstandard expansionary monetary policy, can also reduce the degree of co‐movement of business cycles across countries. From a policy perspective, our work shows that an inflation targeting regime coupled with simultaneous fiscal consolidations can lead to more business cycle synchronization.     

Financial Uncertainty and Business Investment

The paper contributes to the empirical analysis of financial uncertainty and investment from a Post Keynesian perspective. The paper uses the volatility of the exchange rate, the volatility of the stock market index, and the real gold price as indicators for financial uncertainty. An increase in the volatility of a variable is a sufficient, but not a necessary condition for an increase in uncertainty regarding this variable. The effects of changes in uncertainty on investment are investigated econometrically for the United States, the United Kingdom, the Netherlands, Germany and France. Financial uncertainty, we find, has significant negative effects in the US and the Netherlands.     

The reaction of disagreements in inflation expectations to fiscal sentiment obtained from information in official communiqués

Using official communiqués about fiscal policy, we develop a fiscal sentiment indicator, and we verify the reaction of disagreements in inflation expectations to fiscal sentiment. This analysis is relevant to inflation targeting (IT) countries because transparency and communication can influence expectations. The results suggest that a more optimistic fiscal sentiment reduces disagreements in inflation expectations. Estimates show that, for higher disagreements in inflation expectations at 12-month maturity, an optimistic fiscal sentiment can reduce the disagreement more sharply. In turn, the fiscal sentiment effect on the disagreement for the 48-month maturity is stronger the smaller the disagreement is. The results allow us to outline the following policy recommendations. First, an optimistic fiscal environment is important in the task of guiding inflation expectations and reducing inflation uncertainty. Second, fiscal communication is an important tool for the expectations formation process, and therefore it must be carefully managed to help in the task of forward guidance of inflation expectations, being important for the IT regime. Third, both fiscal credibility and monetary policy credibility are important for the expectations formation process, particularly for the reduction of inflation uncertainty, representing aspects that must be preserved in countries that adopt the IT regime.     

Commodity prices and fiscal policy in a commodity exporting economy

This paper analyzes the macroeconomic effects of commodity price shocks on a commodity exporting country. In doing so, we use a DSGE model developed to describe the business cycle in Chile, a copper exporting country. We compare the effects of commodity-price shocks under different fiscal rules. The results show that if the fiscal policy is conducted in a way such that the government saves most of the extra revenues from the higher commodity price, then the macroeconomic effects of a commodity price increase of 10% are an expansion of output below 0.2% and a real exchange appreciation of 0.5%. In contrast, when fiscal policy is highly expansive, the same commodity price increase implies an output expansion above 0.5% and a real exchange rate appreciation of 0.8%. With our model, we also analyze the effects of persistent reduction in the commodity price, the relevance of exchange rate flexibility and the role of imperfect credibility of the fiscal rule.     

Foreign Debt,Foreign Direct Investment and Volatility

We investigate how foreign debt and foreign direct investment (FDI) affect the growth and welfare of a stochastically growing small open economy. First, we find that foreign debt influences the growth of domestic wealth by lowering the cost of capital, while FDI affects the country's welfare by providing an additional source of permanent income. Second, a decline in domestic investment may improve domestic welfare as FDI replaces the gap. Even when the welfare deteriorates, its magnitude is mitigated, leaving more room for discretionary fiscal policy. Third, a fiscal policy aimed to stabilize domestic output fluctuations needs to be conducted not to crowd out the welfare benefit of FDI too much. Fourth, an economy with both types of foreign capital experiences wider welfare swings by external volatility shocks than the one with foreign debt alone, while the welfare effects from domestic volatility shocks are mitigated. The welfare effects of fiscal shocks are much smaller with both types of foreign capital. Lastly, the first-best labor income tax covers the government absorption by the labor's share of total output, and the capital income tax covers the rest. Investment is penalized or subsidized depending on the social marginal cost-gain differential.
