Financial systems and economic growth in South Africa: a dynamic complementarity test

This study examines the relationship between banks, stock markets and economic growth in South Africa. The study attempts to answer one critical question: are stock markets and banks complementary to one another in the process of enhancing economic growth? The complementarity between the stock markets and banks is examined by including a set of interactive terms in a standard growth model, alongside bank development and stock market development proxies. In order to test the robustness of the results, three proxies of stock market development have been used, namely stock market capitalization, stock market traded value and stock market turnover – against the ratio of bank credit to the private sector, a proxy for bank-based financial development. The economic growth is, however, proxied by real GDP per capita. Using the ARDL-Bounds testing procedure, the study finds that the complementarity between stock market development and bank-based financial development is weak and sensitive to the proxy used to measure stock market development.     

Oil shocks and stock volatility: new evidence via a Bayesian,graph-based VAR approach

ABSTRACT

This article examines the temporal dependence between three oil shocks and realized volatility in the stock markets of G20 countries between 1994 and 2019. By applying a novel, graphical, Bayesian VAR (BGVAR) model, we calculate unidirectional linkages of oil and stock volatility with a full and segmented sample. The results suggest an overall causality from stock volatility to oil shocks. For certain short, specific periods, the causal direction reverses. Depending on the country and the source of an oil shock, the magnitude and type of the effect can vary considerably. Specific oil-market shocks occur most often in our full sample. In a time-varying structure, oil supply shocks’ impact on stock volatility is more prominent, and net oil-importing countries’ responses to these shocks are greater than for oil-exporting countries. In addition, we find that relationship dynamics can capture market information, such as global economic growth during the 2008–2009 financial crisis.     

Financial development,economic growth and convergence clubs

To study the role of financial development in economic growth, we apply an array of convergence tests designed to capture nonlinear transitional dynamics to real outputs per capita. Strong evidence of multiple convergence clubs is observed, implying that the clubs are formed based on the initial level of real output per capita and average growth rate. Our empirical results show that the stage of economic growth of each country plays an important role for the composition of the convergence clubs. Furthermore, financial development emerges to be a significant determinant, albeit plays differently in the economic growth of each convergence club.     

Non linear and asymmetric linkages between real growth in the Euro area and global financial market conditions: New evidence

This paper deals with transition mechanisms through which financial market conditions affect real economic growth in the Euro area. The informational content of financial variables for predicting real economic growth is assessed, allowing for asymmetric responses to shocks. A nonlinear framework is developed based on a smooth transition model for which the effects of shocks can vary across business cycles when financial indicators modify both the endogenous and state variables. Global financial variables are shown to significantly affect real growth in the Euro area, particularly during periods of recession. Changes in stock market index and yield slope have asymmetric effects on real growth. In recessionary periods, the slope of the US yield curve does not have a significant impact on growth in the Euro area.     

Financial Development and Economic Growth: The Tunisian Experience

The aim of this paper is to investigate empirically the question of whether financial development leads to economic growth in a small, developing country like Tunisia. The paper focuses on the causal link between finance and economic growth in order to discriminate between several alternative theoretical hypotheses. The results suggest the existence of a stable long-run relationship between the development of the financial sector and the evolution of per capita real output that is consistent with the view that financial development can be an engine of growth in this country.     

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.     

Corporate credit,stock price inflation and economic fluctuations

This study analyses the empirical interaction between real corporate credit, real income, real stock prices, the short-term interest rate and inflation for the Netherlands and the USA. The framework is based on a five-variable structural vector error correction model which identifies the permanent and temporary shocks within the system. Erratic shocks in the real amount of corporate credit and in stock prices could potentially have some impact on inflation in the case of the USA and on real output in the Netherlands. However, the structural VAR analysis also shows that the above-mentioned erratic shocks only explain a small proportion of the variation in inflation and economic activity, and inflation objective shifts and supply side shocks are much more important determinants for economic fluctuations.     

CENTRAL PLANNING LEGACIES: THE LINGERING EFFECTS OF THE GREAT LEAP FORWARD IN CHINA

The Great Leap Forward (GLF) (1958–61) in China was a natural experiment that removed private property rights to achieve rapid growth via central planning, producing immediate famine and death. Using three measures for the GLF, we find that it still exerts a significant negative effect on output per worker in 2004 across Chinese provinces. This result is robust to the use of political factors from the GLF period as instruments. The causal relationship persists after controlling for climate conditions and initial output per capita. Moreover, the causal relationship exists when we change the dependent variable to output per worker in 1978, which refutes the notion that market‐oriented reforms alone explain the difference in income in 2004. Therefore, the GLF has had a lasting, negative effect on output.     

Technological innovations and economic prosperity: A time series analysis

Using a univariate decomposition of per capita real GDP into its permanent trend and irregular components, the objective of this paper is to measure, rank, and compare the relative importance of the major technological innovations of the past two centuries as measured by their contribution to the growth rate of real per capita GDP. The paper uses the growth model and Beveridge and Nelson’s (1981) univariate decomposition method to measure and to compare the economic impact of random technological shocks, as measured by the average increase in real per capita GDP during sub-periods of major technological advancements.     

Economic openness and income growth in developing countries: a regional comparative analysis

This article examines and compares the openness–growth relationship between the high-performing Asian economies (HPAEs) and the rest of the developing world (Sub-Saharan Africa-SSA, South East Asia-SEA and Latin America and Caribbean-LAC). We applied the SYS-GMM estimator to a dynamic standard endogenous growth model which relates economic openness to real per capita income growth. A few key findings emerged from this study. First, economic openness led to increase in real per capita GDP growth in HPAEs and SSA, but not in LAC and SEA. Second, openness to trade accelerated income convergence among countries in SSA, SEA, and HPAEs, however, whereas foreign direct investment inflows accelerated income convergence only in SSA, it rather de-accelerated income convergence in HPAEs. Thirdly, the HPAEs recorded higher positive effect of openness on real per capita GDP growth than any of the other developing regions because they created sufficient stock of human capital that enhanced their absorptive capacity of imported advanced technology. They also created a more stable macroeconomic environment which consolidated the income growth gains from openness. The results of this study highlight the importance of the implementation of policies that are complementary to economic openness in promoting economic growth in the developing world.     

The effects of economic policy uncertainty on China’s economy: evidence from time-varying parameter FAVAR

ABSTRACT

This article explores the effects of China’s economic policy uncertainty (EPU) on its fiscal policy, monetary policy and a wide range of macro-economic variables using a time-varying parameter FAVAR model. Based on monthly data from 07/2003 to 08/2017, the time-varying structure of the model allows us to capture the time-varying characteristics of the macro-economic variables and which channel is relevant. Empirical results reveal that the reaction of monetary and fiscal policies to EPU is highly asymmetric across macro-economic circumstances. Loose monetary and fiscal policies are adopted in response to EPU shocks during the financial crisis, while policies are moderately tightened after the crisis. The China Interbank Offered Rate (Chibor) responds more sensitively and severely than M2 to EPU shocks. Additionally, EPU shocks have a significant and negative impact on economic growth, consumption, exchange rates, bonds and the stock market, but showing a positive impact on credit, real estate and fixed asset investment (which might be due to China’s special economic market environment and the high investment return). The results indicate that EPU shocks significantly affect macroeconomic fundamentals through precautionary savings and financial market channels but lose their effectiveness through a ‘real options’ effect.     

An empirical study of credit shock transmission in a small open economy

In this paper, we identify and estimate the dynamic effects of foreign (US) and national (Canadian) credit shocks in a small open economy. We use standard credit spreads as proxies to the external finance premium. Our first result suggests that the US and Canadian credit spreads contain substantial forecasting power for several measures of the Canadian real economic activity, especially during the recent financial crisis and its aftermath. Secondly, an adverse US credit shock generates a significant and persistent economic slowdown in Canada: the national external finance premium rises immediately while interest rates, credit aggregates, output and employment indicators decline. Variance decomposition reveals that credit shocks have a sizeable effect on real activity measures, leading indicators and credit spreads. Yet, the unexpected shocks in domestic credit spreads are not able to generate any significant dynamic response of the real activity once we control for the US credit market conditions.     

Oil booms and inequality in Iran

We study the response of income inequality to positive per capita oil and gas revenue shocks in Iran. Using historical data from 1973 to 2016 and vector autoregression (VAR) as well as vector error correction (VECM) model‐based impulse‐response functions, we find a positive and statistically significant response of income inequality to oil booms. We also explore possible channels through which oil booms may increase inequality, including private sector credit growth, construction investment, international trade (imports) and real economic output. We find that following an oil boom, higher imports, private sector credit growth, and real economic output can explain the increased income gap to a certain degree in Iran's oil‐based economy. Our analysis can help policymakers evaluate and accommodate the possible positive or negative effects of inequality in Iran resulting from the 2016 lifting of the embargo against the country.     

Research output and economic growth in G7 countries: new evidence from asymmetric panel causality testing

Recent studies have shown increasing interest on the relationship between research output and economic growth. The study of such a relationship is not only of theoretical interest, but it can also influence specific policies to improve the quality, and probably the quantity of research output. This article has studied this relationship in G7 countries using the asymmetric panel causality test of Hatemi-J (2011). Our results show that only the UK shows a causal relationship from the output of research to real GDP. However, when the signs of variations are taken into account, there is an asymmetric causality running from negative research output shocks to negative real GDP shocks.     

The impact of product market competition on GDP per capita growth in the EU countries: does the model of capitalism matter?

This article assesses whether the intensity of product market competition is a factor affecting economic growth (measured by the growth rate of real GDP per capita) and whether this impact depends on the model of capitalism. The study covers the 1997–2015 period and all EU28 countries. Product market competition is measured by two types of variables: product market regulation indicators and the number of enterprises. New elements in the analysis include, among others, nonlinear impact and overlapping observations. The regression equations are estimated on the basis of Blundell and Bond’s GMM system estimator. The results generally indicate that stronger product market regulations (and theoretically lower product market competition) are linked with faster growth of output. However, the impact of product market competition on economic growth depends on the type of capitalism. For post-socialist countries, unlike the Western European model of capitalism, more regulation tends to reduce the rate of economic growth.

Insurance development,banking activities,and regional output: evidence from China

This paper applies panel cointegration tests and panel vector error correction models to investigate the interrelationship among the banking sector, insurance market, and regional output based on the samples from 25 Chinese provinces. We first find that there is a fairly strong long-run cointegrating relationship among real GDP, banking credit, and real insurance premiums. Second, both insurance markets (life and non-life) and the banking sector have a positive effect on real output. Third, we determine that banking activities and economic growth exhibit long-run and short-run bidirectional causalities. Fourth, there is fairly strong evidence in favor of the hypothesis for the long-run bidirectional causal relationships between insurance premiums and economic growth, taking into account the critical channel of the banking sector. Finally, we provide some beneficial suggestions for investors and policy-makers.     

On poverty traps,thresholds and take-offs

Recent studies on economic growth focus on persistent inequality across countries. In this paper we study mechanisms that may give rise to such persistent inequality. We consider countries that accumulate capital in order to increase the per capita income in the long run. We show that the long-run growth dynamics of those countries can generate a twin-peak distribution of per capita income. The twin-peak distribution is caused by (1) locally increasing returns to scale and (2) capital market constraints. These two forces give rise to a twin-peaked distribution of per capita income in the long run. In our model investment decisions are separated from consumption decisions and we thus do not have to consider preferences. Empirical evidence in support of a twin-peak distribution of per capita income is provided.     

Global distribution and dynamics of economic freedom: Non-parametric approach

The paper exploits the distributional dynamics and structural changes in the endogenous distribution of economic freedom across countries over time by utilizing the Rosenblatt–Parzen Kernel density estimator compared to the original distribution based on the methodology proposed by the Heritage Foundation. We utilize the distribution of economic freedom as a tool to identify which policies enhanced the overall level of economic freedom. We develop the distribution of endogenous economic freedom by decomposing effects of economic freedom on the level of income per capita in IV–2SLS estimation framework for a panel of 134 countries to identify the effect of institutions of economic freedom on the level of per capita income. Structural estimates indicate that improvements in the monetary, fiscal, and labor freedom exert the strongest direct effect on the level of economic freedom and indirect effect on the level of real income per capita. Our study demonstrates considerable differences between the original and endogenous distributional dynamics of economic freedom over time. In exploiting the non-parametric setting of endogenous economic freedom, we identify a recent emergence of twin-peak distribution across countries where developing nations have improved the level of economic freedom considerably compared to the initial year.     

Convergence and the Caribbean

This paper examines the convergence experience of selected Caribbean countries. It examines evidence of reduced dispersion in real per capita income—Sigma convergence—and ‘catch up’ growth across the group—Beta convergence. Estimation of the Solow—Swan cross-section model for the Caribbean shows weak evidence of β and σ convergence. However, structural instability and evidence of divergence over the sample period, suggest this convergence to be spurious. Further tests on individual country data showed an absense of steady state convergence for any country over time. Institutional structures and adjustments to economic shocks appear to have been important for the determination of per capita income in the long run.
