Openness and the Effects of Fiscal and Monetary Policy Shocks on Real Output in Nigeria (1960–2003)*

Abstract: This study investigates the effects of monetary and fiscal policies on the real output growth in a small open economy. It is a country‐specific, time series study that verifies the implication of increasing economic openness on the efficacy of monetary and fiscal policy. A modified GARCH model was used to estimate the anticipated and unanticipated shocks. Two measures of fiscal and monetary shocks were combined with openness and real oil price shocks in a VECM model to assess the effects of anticipated and unanticipated policy shocks on the output equations. The empirical results showed that anticipated and unanticipated fiscal and monetary shocks had no significant positive effects on real output. This suggests that the open macroeconomic version of the policy ineffectiveness proposition was valid for both monetary and fiscal policy shocks in Nigeria. This is in consonance with earlier works in this area. Furthermore, the degree of openness and oil price shocks had a negative implication on the efficacy of macroeconomic policy in Nigeria; also in agreement with the Dutch Disease Syndrome. Finally, the policy implication of this study therefore is that trade liberalization policy should be implemented cautiously. The Nigerian economy is weak to withstand the unwholesome consequences of full economic integration.     

Reactions to Shocks and Monetary Policy Regimes: Inflation Targeting Versus Flexible Currency Board in Sub‐Saharan Africa

The paper examines the monetary policy actions through which central banks in sub‐Saharan Africa have tried to eliminate the negative impacts of the shocks facing their economies. We compare two different monetary policy regimes: a currency board regime (in the CFA zone) and an inflation targeting policy regime (Ghana and South Africa) when central banks respond to demand, supply, and fiscal shocks. We extend the usual forecasting and policy analysis system models to replicate the economic features of these economies during the period 2002–12 and to evaluate the impact of several policies in response to these shocks. We find that both policies are inappropriate in helping the economies escape from the effects of negative demand shocks, both are essential when negative shocks to primary balance occur, while inflation targeting dominates the currency board regime as a strategy to cope with positive shocks to inflation.     

Sustainability of the fiscal imbalance and public debt under fiscal policy asymmetries in Sri Lanka

This paper investigates the sustainability of Sri Lanka’s fiscal imbalance and public debt. To test for sustainability of the fiscal imbalance, the study applies a symmetric ARDL (autoregressive distributive lag) technique to estimate a government intertemporal budget constraint. And to test for sustainability of public debt, it applies an asymmetric ARDL technique to estimate a fiscal reaction function, which allows for differential responses in the primary budget balance depending on whether shocks to regressors are positive or negative. Annual data for the period 1961–2018 are used in the estimations. The results indicate that Sri Lanka’s fiscal management is inconsistent with strong form sustainability, which requires that expenditures not grow faster than revenues. However, estimation of the fiscal reaction function finds robust evidence for fiscal policy asymmetries. Evidence emerges that Sri Lanka’s fiscal policy stance is procyclical with strong stabilization tendencies in economic expansions that are not sustained in contractions. Against upsurges in the debt-to-GDP ratio, authorities are found to pursue fiscal consolidation, thus suggesting weak form sustainability.     

政府支出与经济波动——基于省级面板数据的实证分析

政府支出能否起到稳定经济增长的作用是一个值得研究的重要问题。使用1987-2013年30个省市自治区的面板数据,文章考察了政府支出对我国经济波动的影响。在考虑政府支出规模的内生性后,2SLS估计结果发现政府支出对经济波动的影响具有两面性。一方面政府支出规模主要发挥了财政自动稳定器作用,因而减少了经济波动;另一方面,政府支出变动对总量产出冲击较大,从而增加了经济波动。进一步控制了贸易开放、通货膨胀、货币政策冲击、金融发展和产业结构等因素,估计结果表现出较好的稳健性。研究结论意味着,在保持经济稳定增长方面,需要权衡政府支出规模与政府支出变动对经济波动的影响。     

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.     

财政支出、居民消费与经济波动——基于动态随机一般均衡模型(DSGE)的分析

在动态随机一般均衡(DSGE)模型中引入财政支出冲击和居民消费习惯,将财政支出分为生产性支出和消费性支出,分别纳入生产函数和总消费函数,通过DSGE模型模拟了财政支出对居民消费、产出、就业、投资等经济变量的动态影响。模拟结果显示财政支出增加对居民消费产生了挤出效应,而对产出、就业等经济变量产生挤入效应。考虑消费习惯后,经济变量对外生冲击的响应呈驼峰状,并且影响程度加大。因此,合理划分政府支出的类型并恰当评估居民的消费习惯对把握财政政策的操作力度甚为重要。     

Sectoral and aggregate estimates of the cyclical behavior of markups: Evidence from Germany

Sectoral and Aggregate Estimates of the Cyclical Behavior of Mark-ups: Evidence from Germany. — The paper presents evidence of the cyclical behavior of the price to marginal cost ratio for Germany. Average markups are estimated both for two-digit manufacturing industries and for the aggregate economy, the results being quite similar once the difference between gross output and and value-added markups is accounted for. Over the business cycle, markups appear to be countercyclical for most parameter constellations. This is interpreted as empirical support for business cycle theories that rely on aggregate demand shocks to affect markups inversely, thus producing procyclical real wages and productivity without having to assume technology shocks.     

The Effects of Fiscal Policy in a Small Open Economy with a Fixed Exchange Rate

We study the empirical effects of fiscal policy in Denmark since the adoption of a fixed exchange rate policy in 1982. Denmark’s fixed exchange rate implies that the nominal interest rate remains fixed after a fiscal expansion, facilitating a substantial impact of the fiscal stimulus on the real economy. On the other hand, the large degree of openness of the Danish economy means that a sizeable share of the fiscal stimulus will be directed towards imported goods. Our results suggest that the ‘monetary accomodation channel’ dominates the ‘leakage effect’ in the short run. We demonstrate that fiscal stimulus has a rather large impact on economic activity in the very short run, with a government spending multiplier of 1.1 on impact in our preferred specification. We also find that the effects of fiscal stimulus are rather short-lived in Denmark, with the effect on output becoming insignificant after around two years. The fiscal multiplier is above 1 only in the first quarter, and drops to 0.6 one year after the shock. We also find that in the short run, the government spending multiplier is larger than the tax multiplier. Finally, we demonstrate that exogenous shocks to government spending account for less than 10 % of the movements in output over the business cycle in Denmark.     

Sub-Saharan Africa's rising public debt stock: Is there a cause for concern?

The study investigated public debt sustainability in sub-Saharan Africa (SSA) by testing the reaction of the primary balance to positive and negative shocks in public debts in a panel of 45 SSA countries. The study adopts the innovative nonlinear fiscal reaction function and the dynamic panel threshold model to account for the potential asymmetric phenomenon in the public debt series. In line with extant studies, the study found that public debts in SSA are weakly sustainable and there is a highly procyclical fiscal policy bias in SSA countries, particularly in resource-rich countries, indicating that governments' fiscal policy responses are expansionary during economic upturns and contractionary during recessions, which may aggravate recessions and worsen debt situations across SSA. For robustness, the study compares the results with emerging and developed economies. The results indicate that in advanced economies, public debt is sustainable and that fiscal policy response is countercyclical. The research and policy implications are discussed.     

Oil shocks and endogenous markups: results from an estimated euro area DSGE model

This paper estimates a linearised DSGE model for the euro area. The model is New Keynesian and allows for a role for oil usage and endogenous price markups. The importance of shocks to monetary policy and oil prices is estimated to have declined in the post-1990 period, in line with the higher predictability of policy and the fall in the persistence and—to a lesser extent—variability of oil disturbances. Counterfactual exercises show that oil efficiency gains would alleviate the inflationary and contractionary consequences of oil shocks, while higher wage flexibility would help ease the impact on real output at the expense of larger inflationary pressures. While we report evidence of “countercyclical” price markups, the rise in markups induced by an oil disturbance is not found to considerably amplify the inflationary and contractionary effects of the shock. The paper discusses the policy implications of our empirical results for the euro area economy.     

The persistence of government expenditure shocks and the effect of monopolistic competition on the fiscal multiplier

In this paper, we demonstrate that the influence of monopolisticcompetition in the product market on an economy's impact responseto fiscal shocks depends on the persistence of these shocks.While short-lived increases in lump-sum financed governmentexpenditure have a stronger effect on labor supply if pricesare above marginal costs, the response of employment decreasesin the markup if shocks are highly persistent. However, we alsoshow that, while the impact response of labor supply to temporarygovernment expenditure shocks may be reduced by monopolisticcompetition, the fiscal multiplier is always higher if firmshave market power.     

Effects of foreign and domestic economic policy uncertainty shocks on South Korea

This paper investigates the effects of foreign and domestic economic policy uncertainty shocks on South Korea via structural VARs. The results show that both foreign and domestic policy uncertainty shocks exert negative and significant impacts on South Korea. Foreign economic policy uncertainty shocks are found to be more dominant than domestic economic policy uncertainty shocks in influencing the Korean output. The results also indicate that economic policy uncertainty that originates from foreign countries is a significant source of disturbance to the Korean economy, but domestic policy uncertainty plays a rather limited role in explaining Korean business fluctuations.     

Negative economic shocks and child schooling: Evidence from rural Malawi

This study investigates the impacts of negative economic shocks on child schooling in households of rural Malawi, one of the poorest countries in sub-Saharan Africa. Both individually-reported and community-level shocks are investigated. There is evidence that community-level shocks negatively impact the school enrolment of children. The point estimates suggest that this effect is larger when shocks and school enrolment are reported by men as compared with women. However, we cannot conclude with statistical confidence that the impact of idiosyncratic shocks is larger when reported by males than when reported by females. Similarly, although the point estimates suggest that the impact of community-level shocks on the school enrolment of children is larger than that of idiosyncratic shocks, we cannot conclude with statistical significance that the impacts of community-level and idiosyncratic shocks are different.     

A history of aggregate demand and supply shocks for the United Kingdom, 1900 to 2016

This paper presents a history of aggregate demand and supply shocks spanning 1900 – 2016 for the United Kingdom. Sign restrictions derived from a workhorse Keynesian model are used to identify the signs of those shocks. We compare the 30 largest shocks implied by a vector autoregressive model in unemployment and inflation with the narrative historical record. Our approach provides a new perspective on well-known events in economic history. We highlight two episodes of particular interest: an aggregate supply shock in the late 1920s, which we attribute to changes in the bargaining power of labor, and positive aggregate demand shocks in the mid-1970s, which we attribute to fiscal policy.     

地方政府财政支出政策效果差异化分析——基于四川省面板数据

基于四川省1995—2006年面板数据,利用工具变量评估财政支出乘数模型并借鉴分位数模型思想,发现财政支出政策不利于缩小区域内经济发展差距,即对于经济发展水平越高的地方,财政支出效果越好,原因在于其资本利用能力,即财政支出对投资的溢出效应,造成第二产业增长幅度不同,最终呈现出财政支出效果不同.认识这一点对于在经济处于新常态背景下,有利于优化开发财政产业政策的作用空间.     

财政分权、空间外溢与区域经济增长

分税制改革以后,税收体系被划分为中央与地方两大部分,正式建立起以分税制为中心的财政分权体制。各地区的财政分权程度不仅对本地经济增长有直接影响,还对其他地区的经济增长有间接影响,即存在空间溢出效应。利用我国2005年至2018年31个省（市、自治区）的面板数据,运用空间面板模型,估计和检验财政分权对经济增长的空间效应。研究结果表明：各地区的财政分权不仅促进本地经济增长,还对其他地区的经济增长有显著正向溢出效应。     

Competition in the Chinese market: Foreign firms and markups

This study addresses the issues of whether foreign firms outperform domestic firms in markups and whether the presence of foreign firms dampens the markup of their local counterparts in the Chinese market. Analysis of a firm-level panel dataset, we find foreign-invested enterprises (FIEs), particularly those not from Hong Kong–Macau–Taiwan, charging a higher markup. Estimations on the determinants of markups highlight the important roles played by technological capability and intangible assets. The potential channels and mechanisms are also discussed. Entering the Chinese market through joint ventures helps FIEs raise markups, and this effect is notable for HMT–FIEs, which might have a relative advantage of cultural proximity than other FIEs. Sharing equality with national capital to construct political connection (guanxi) also helps facilitate markups. Crucially, foreign presence is positively related to local firms’ markups, suggesting that the spillover and linkage effects dominate the competition pressure brought about by foreign direct investment.     

中国财政赤字和国债政策的经济增长效应研究

本文通过构建一个VAR模型,选取财政赤字率和国债负债率为财政政策指标,来分析财政政策对经济增长和通货膨胀的影响。实证显示:财政赤字增加短期能够促进经济增长,但长期对经济增长无效,且不会引起通货膨胀;相反,负债率增加虽在短期内对经济增长影响不明显,但长期具有显著负影响,同时会导致通货紧缩。结论表明,国家应对金融危机的积极财政政策短期是有效刺激经济增长的,但是长期是无效的,尤其是通过大量发行国债弥补赤字扩大财政支出的政策,对经济增长有较大的负作用。因此,本文认为目前政府应该给市场更多自由,减少对市场的政策干预。     

LINKING POVERTY AND INCOME SHOCKS TO RISKY SEXUAL BEHAVIOUR: EVIDENCE FROM A PANEL STUDY OF YOUNG ADULTS IN CAPE TOWN

Is there a link between household income and income stress, and risky sexual behaviour of young people? Anecdotal and qualitative evidence suggests this may be the case, but there is little quantitative research measuring this relationship. We use two waves of new data from the Cape Area Panel Study to investigate this link for 2,993 African and coloured youths aged 14 to 22 in 2002. In the process, we discuss one type of research design that could allow for a causal interpretation of the effect of income poverty on HIV risk. This design plausibly separates out the effect of income stress from the effect of living in a poor household by comparing behaviours across households with and without negative economic shocks, conditional on baseline income. Our results indicate that females in poorer households are more likely to be sexually active in 2002 and more likely to sexually debut by 2005. In addition, girls in households experiencing negative economic shocks are more likely to reduce condom use between 2002 and 2005. However, they are less likely to have multiple partners in 2002 or have transitioned to multiple partners by 2005. Males who experienced a negative shock are more likely to have multiple partners. Despite the tight research design for assessing shocks, the findings on the impacts of shocks do not generate clear recommendations for policy. There appears to be no systematic difference in condom use at last sex by household income levels or income shocks.     

Effect of Money Supply on Real Output and Price in China

Over the past 30 years, China has achieved remarkable long-term economic growth. Using quarterly data, we study the effects of money supply on real output and inflation in China between 1993 and 2008. To this end, we use money supply shocks afler filtering out the expected component of the money supply. Our findings provide evidence supporting the asymmetric effect of positive and negative money supply shocks on real output and inflation in China. That is, real GDP growth in China responds to negative money supply shocks but not positive money supply shocks. In addition, inflation responds to positive money supply shocks but not negative money supply shocks. We conclude that the People＇s Bank of China＇ s policy of steady monetary growth appears to be appropriate. Our study offers important policy implications for China.
