Corruption,growth, and growth volatility

While the existing studies focus on the corruption–growth relationship, this paper introduces a new focus involving corruption and growth volatility. The Ehrlich–Lui (1999) framework provides the theoretical background of the paper, which produces testable hypotheses regarding the corruption–growth and the corruption–growth volatility relationship. The cross-section dataset that is used in the empirical analysis contains 121 developed and developing countries. In terms of the relationship between the governance-related variables and growth rates, only corruption control and government effectiveness significantly and adversely affect the average growth rate. Regarding the relationship between growth volatility and governance-related variables, the results suggest that higher corruption control, expropriation risk control, government effectiveness, and government consumption decrease growth volatility.     

Output volatility and economic growth

This paper proposes a new instrument to identify the causal effect of output volatility on economic growth, which is based on (exogenous) volatility spillovers from abroad. Cross-section evidence from 128 countries points to a negative effect of volatility on growth.     

The link between economic growth and growth volatility

This paper investigates the relationship between economic growth and growth volatility through simultaneous equations system. By employing the identification through heteroskedasticity method of Rigobon (Rev Econ Stat 85:777–792, 2003) and using a panel of 158 countries over the period 1960–2010, we find that output volatility is detrimental to economic growth, suggesting that stabilization policies to mitigate short-run economic fluctuations contribute to long-run economic growth. And economic growth accelerates output variability, supporting the feedback effects from growth to the volatility. The evidence is robust to a number of sensitivity tests.     

Financial structure on growth and volatility

By applying the pooled mean group estimator to a large panel up to 40 countries over the 1960–2009 period, this study finds that financial structure is significantly cointegrated to both economic growth and its volatility. In particular, the relationship is positive in nature, suggesting that more market-based countries enjoy faster economic growth but suffer more from economic fluctuations in the long run. Accordingly, in sharp contrast to the existing evidences, we conclude that the architecture of an economy's financial system matters for real sector performance. Moreover, the findings are robust to a variety of sensitivity checks, including the problem of endogeneity, the use of different financial structure (and growth volatility) indicators, the inclusion of extra growth (volatility) determinants, and the control of cross-sectional dependence in the panel data.     

On the link between volatility and growth

A model of growth with endogenous innovation and distortionary taxes is presented. Since innovation is the only source of volatility, any variable that influences innovation directly affects volatility and growth. This joint endogeneity is illustrated by working out the effects through which economies with different tax levels differ in their volatility and growth process. We obtain analytical measures of macro volatility based on cyclical output and on output growth rates for plausible parametric restrictions. This analysis implies that controls for taxes should be included in the standard growth-volatility regressions. Our estimates show that the conventional Ramey–Ramey coefficient is affected sizeably. In addition, tax levels do indeed appear to affect volatility in our empirical application.     

Forms of democracy and economic growth volatility

Using a panel of 140 countries over the 1975–2007 period, we disaggregate democracies across five institutional dimensions (government forms, electoral rules, state forms, number of veto players, and age of democracies), to study the precise forms of democracy that may explain the lower economic growth volatility (EGV) in democracies compared to dictatorships, usually emphasized by the literature. We find that, while all government forms decrease EGV to the same extent, proportional electoral rules outperform majoritarian and mixed electoral rules, suggesting a role for a more inclusive political decision-making process. In addition, EGV is significantly lower in unitary states, suggesting a role for a limited separation of power between the central government and the local authorities, while the effect of the number of veto players and the age of democracies is significant only in developed countries. Consequently, the choice between various forms of democracy may not be neutral for EGV, and, possibly, for countries' development path.     

Exchange rate volatility and export growth in Nigeria

This article examines the impact of exchange rate volatility on Nigeria's exports to its most important trading-partner–the United States over the quarterly period January 1980 to April 2001. Using cointegration and vector error correction (VECM) framework, empirical tests indicate the presence of a unique cointegrating vector linking real exports, real foreign income, relative export prices and real exchange rate volatility in the long run. Furthermore, the results show that increases in the volatility of the real exchange rate raise uncertainty about profits to be made which exert significant negative effects on exports both in the short- and long-run. Our results also show that improvements in the terms of trade (represented by declines in the real exchange rate) and real foreign income exert positive effects on export activity. Most importantly, we found that the trade liberalization and economic reform policies implemented in the post-1986 structural adjustment period contributed to Nigeria's export performance. Overall, our findings suggest that Nigeria's exporting activities can be further boosted by policies aimed at achieving and maintaining a stable competitive real exchange rate.     

Exploring GDP growth volatility spillovers across countries

This study takes a portfolio approach to investigate GDP growth volatility spillovers among 120 countries of the world during the 1960–2017 period. Based on the ratios of growth rate to standard deviation, we rank these countries in pools of high-, midsize-, and low-income growth. Using a spillover index that is based on variance decompositions under a vector autoregressive framework, we analyze the sources of growth volatility dynamics in the world in terms of volatility proportions from and to others. We find that high-income growth countries are net transmitters, while low-income growth countries are net recipients of growth volatility. We also find that it takes several years for low-income growth countries to absorb growth shocks of global nature. Overall, our analyses illustrate the importance of partnership in risk sharing as it is related to portfolio strategies and risk management.     

Political democratization, economic liberalization, and growth volatility

This study empirically investigates the effects of political and economic liberalization on growth volatility using a difference-in-difference method for a sample of 158 countries over the 1970-2005 period. The results show that, when examined separately, economic liberalization leads to a significant reduction in volatility while democratization is not followed by a decrease in growth volatility. For countries that undertake only one liberalization, opening up the economy to international trade reduces volatility in growth; becoming a democracy, on the other hand, seems to increase macroeconomic instability. For countries that implement both political and economic liberalizations, no statistically significant effect on volatility is detected. These results serve to provide additional support for the policy recommendation that developing countries should liberalize their economy first and then consider political liberalization.     

Scaling the volatility of GDP growth rates

The distribution of shocks to GDP growth rates is found to be exponential rather than normal. Their standard deviation scales with GDP^β where β=−0.15±0.03. These macroeconomic results place restrictions on the microeconomic structure of interactions between agents.     

Government size, composition, volatility and economic growth

This paper analyses the effects in terms of size and volatility of government revenue and spending on growth in OECD and EU countries. The results of the paper suggest that both variables are detrimental to growth. In particular, looking more closely at the effect of each component of government revenue and spending, the results point out that i) indirect taxes (size and volatility); ii) social contributions (size and volatility); iii) government consumption (size and volatility); iv) subsidies (size); and v) government investment (volatility) have a sizeable, negative and statistically significant effect on growth.     

The impact of volatility on growth in China

China’s path to emerging as the world’s second largest economy has not been a smooth one. This paper considers whether the volatility of growth has had an impact on the trend rate of growth. In doing so it aims to promote a better understanding of the determinants of China’s impressive trend rate of growth and also shed light on questions such as whether the trend rate of growth might have been even higher had the government and central bank been better able to offset volatility. Utilizing a GARCH-M model, the results of the empirical analysis suggest that the impact of volatility has been either positive or insignificant, but not negative.     

Declining output growth volatility: A sectoral decomposition

A decomposition of the U.S. aggregate output growth volatility using two-digit industry-level data shows that more than 60% of the post-1983 reduction in aggregate output growth volatility is attributed to the lowered comovement in total factor productivity (TFP) growth between industries. In contrast, stabilized input and TFP growths within an industry contribute little.     

Inflation volatility,economic growth and monetary policy in Bangladesh

This article provides an overview of the trends and movements of CPI-inflation in Bangladesh since the early 1950s and examines the key issues in rule-based monetary policy for price stability, implying low and stable inflation, in this country. Under a fixed exchange rate system, inflation in Bangladesh was moderately high and volatile during the 1950s and 1960s. Since the country’s independence from Pakistan in 1971, inflation in Bangladesh has remained moderately high on average and highly volatile and persistent under a fixed-pegged exchange rate system or under a managed floating system since 2003. Using data from the early 1970s or earlier depending on data availability, the article undertakes both Granger-causality and the structural vector autoregression (SVAR) analysis with two models. The first model is comprised of such variables as inflation, the real interest rate, the real exchange rate and output growth, and the second model is comprised of the volatilities of money growth, real output growth and inflation. Then, based on the empirical findings, the article concludes that a rule-based monetary policy, namely monetary targeting or inflation targeting, remains appropriate for Bangladesh provided that it adopts a more flexible, if not freely floating, exchange rate system. The article suggests that the use of monetary policy to achieve multiple objectives under a fixed-pegged exchange rate system creates a time-inconsistency problem, reduces monetary policy credibility and makes it (monetary policy) ineffective in lowering inflation and its volatility. Low credibility of monetary policy in particular raises inflation persistence. Within the present monetary-policy framework in Bangladesh, the article illustrates how the fixed-pegged exchange rate system has generated money growth volatility in the presence of large-scale inflows of overseas workers’ remittances and readymade garments export earnings. This does not seem to be a concern of the central bank of Bangladesh (Bangladesh Bank); rather, it (Bangladesh Bank) pursues monetary-base targeting to keep inflation low and stable after considering economic growth. The consequent diminishing credibility of monetary policy has kept inflation volatile and persistent, which has adversely affected economic growth.     

The effect of growth volatility on income inequality

This paper assesses the long-run effect of growth volatility on income inequality using a comprehensive panel of annual U.S. state-level data during the 1945 to 2004 period. Using the pooled mean group (PMG) estimator, we find evidence supporting the hypothesis that larger growth volatility positively and significantly associates with higher income inequality. Our key finding is robust to alternative lag structures, conditioning variables, inequality measures, volatility indicators, time periods, and panel estimators. Our key finding does change for asymmetric effects, where larger growth volatility positively and significantly associates with higher income inequality only for positive economic growth. The volatility effect proves positive, but insignificant, for negative economic growth.     

Does exchange rate volatility hinder export growth?

The paper examines the impact of exchange rate volatility on trade using an ARCH-in-mean model. The advantages of this statistical approach vis-a-vis earlier approaches is that it provides more efficient coefficient estimates and avoids the problem of spurious regressions. Exchange rate volatility was found to have a negative impact on Canadian and Japanese exports to the United States and on Australian exports to the world. For Sweden, the United Kingdom and the Netherlands, the relationship was found to be positive. The magnitude of the impact of a 10% increase in exchange rate volatility on export volumes was found to range from a reduction of 7.4% (Canada) to an increase of 5% (Sweden). The results indicate that exports invoiced in the importer's currency are affected negatively by exchange rate volatility, and exports invoiced in the exporter's currency are affected positively. A partial equilibrium, profit maximization model is derived to support these findings.     

Sovereign credit ratings,growth volatility and the global financial crisis

Using monthly data from January 1996 to May 2010 for a panel of 76 developed and emerging economies and adopting an instrumental variable (IV) estimation technique by correcting for both heterogeneity and endogeneity with the generalized two-stage least squares (G2SLS, EC2SLS) procedure method suggested by Balestra and Varadharajan-Krishnakumar (1987) and Baltagi and Li (1995), this article provides empirical evidence that volatility of per capita GDP growth is reduced when there are positive changes in credit ratings; in other words when sovereign credit risk improves. To deal with potential simultaneity between sovereign credit ratings and output volatility, a system (3SLS) approach is undertaken, and our findings remain robust. By weakening the volatility dampening effects of ratings changes, it is found that the global financial crisis (GFC) has enhanced macroeconomic volatility. One of the channels via which sovereign rating changes affect growth volatility is the financial markets’ repricing of sovereign default risk that is reflected in sovereign credit default swap (CDS) spreads and its volatility.     

A spatial econometric analysis of the regional growth and volatility in Europe

Based on a sample of 1,084 European regions (EU15) from 1995 to 2004, we estimate the relationship between the average growth rate of GDP per capita and the volatility of the growth rate allowing for spatial effects. The spatial lag and spatial error models show that the regional per capita growth rate and volatility are significantly positively related on average. However, the inclusion of country interaction terms reveals that the volatility impact is not uniform across countries. In particular, the relationship between growth and volatility is significantly positive for the majority of countries but significantly negative for three countries (namely Finland, Italy, and Ireland).

宏观经济景气波动对就业增长的影响

中国不成熟的市场经济和特殊的人口环境使得用就业弹性和奥肯定律均无法有效反映我国经济增长与就业关系,更无法刻画经济波动对就业的冲击。本文从宏观经济景气波动影响就业增长的三个路径：劳动力供给、劳动力需求和政府公共就业政策来建立系统的分析模型,以探析经济波动与就业增长的长期均衡关系和滞后冲击效应。在劳动力供给系统中,经济波动使经济活动人口增多,加快了就业增长;在劳动力需求系统中,经济波动不利于经济增长,从而不利于劳动力需求增长;在政府就业促进政策系统中,社会保障和就业的投入缓和了经济波动对就业增长的冲击。
