The poverty–vulnerability–resilience nexus: Evidence from Bangladesh

Vulnerability and resilience lie at the core of the new paradigm governing natural disaster risk management frameworks. However, empirical understandings of socio-economic resilience and its links with poverty and vulnerability are limited. This paper presents an empirical investigation of socio-economic resilience to natural disasters in a tropical cyclone-prone coastal community in Bangladesh. The results indicate that the cyclone in question had negative impacts on the community, particularly in terms of income, employment and access to clean water and sanitation. Consistent with the findings of the social vulnerability literature, our results also suggest that the poor were more vulnerable and suffered significantly higher economic, physical and structural damage. However, this high vulnerability did not necessarily lead to low resilience, as these individuals exhibited a greater ability to withstand the shock compared to their non-poor neighbors. This refutes the flip-side hypothesis of the link between vulnerability and resilience (i.e. vulnerability is the flip side of resilience). The findings imply that the increased risk of tropical cyclones is likely to reduce incomes and standards of living among the tropical coastal communities. However, the burden of these adverse impacts is unlikely to be disproportionally borne by the poorer segment of the society.     

Finance–growth nexus: does causality withstand financial liberalization? Evidence from cointegrated VAR

The main finding of the paper is that, contrary to Rousseau and Wachtel (Economic growth and financial depth. Is the relationship extinct already? UNU-Wider discussion paper no. 2005/10, 2005), a long-run equilibrium relationship between financial and economic development is identified with data up to 2006—well over the financial openness boom of the nineties—in countries whose history is characterized by numerous years of high inflation and/or episodes of crisis or other structural change. Also, financial openness, or lack thereof, proves to be an important feature both in explaining differences in sensitivity of financial development to capital accumulation and in determining the direction of causality between financial and economic development. The paper finds that bidirectional causality between economic and financial development is not as frequent an outcome as in Luintel and Khan (J Dev Econ 60:381–405, 1999), and in several cases, Joan Robinson’s (The generalization of the general theory in the rate of interest, and other essays, Macmillan, London, pp 67–142, 1952) statement on the primacy of economic development over finance is supported by the estimations.     

What matters in the finance–growth nexus of advanced economies? Evidence from OECD countries

Over the last decades, a large strand of finance and growth literature has provided ample evidence on the importance of financial deepening for economic development. Yet, recently, the focus of public debate has shifted towards the role of the financial system structure, an area in which empirical research remains relatively sparse and exploratory in nature. With this article, we aim to contribute to that debate by analysing the role the financial system structure plays in economic growth and risk. Focusing on stock markets and studying OECD economies over 1994–2013, we find that, ceteris paribus, financial systems with relatively larger stock markets facilitate economic growth and dampen economic risk. Our findings remain robust under application of instrumental variable and system generalized method of moments estimators, as well as when we use an alternative definition of stock market development, estimate median regressions, examine relatively high-frequency annual data, control for systemic banking crises or apply quadratic specifications. We find no such effect for private bond markets or private credit volume. Overall, our results suggest that financial system structure matters for the economic development of advanced economies and highlight the importance of a debate about the optimal structure of an economy’s financial system.     

Re-examining the threshold effects in the inflation–growth nexus with cross-sectionally dependent non-linear panel: Evidence from six industrialized economies

This paper analyzes the empirical relationship between inflation and output growth using a novel panel data estimation technique, Panel Smooth Transition Regression (PSTR) model, which takes account of the non-linearities in the data. By using a panel data set for 6 industrialized countries that enable us to control for unobserved heterogeneity at both country and time levels, we find that there exists a statistically significant negative relationship between inflation and growth for the inflation rates above the critical threshold level of 2.52%, which is endogenously determined. Furthermore, we also control cross-section dependency by using the CD test modified to non-linear context and remedy cross-section dependency with Seemingly Unrelated Regression Equations through Generalized Least Squares (SURE-GLS) and newly proposed Common Correlated Effects (CCE) estimation techniques. We find that these methods change the critical threshold value slightly. The estimated threshold values from these estimation methods are 3.18% and 2.42%, respectively.     

Is energy consumption effective to spur economic growth in Pakistan? New evidence from bounds test to level relationships and Granger causality tests

The present study investigates the relationship between energy (renewable and nonrenewable) consumption and economic growth using Cobb–Douglas production function in case of Pakistan over the period of 1972–2011. We have used the ARDL bounds testing and Gregory and Hansen (1990) structural break cointegration approaches for long run while stationarity properties of the variables have been tested applying Clemente-Montanes-Reyes (1998) structural break unit root test.Our results confirm cointegration between renewable energy consumption, nonrenewable energy consumption, economic growth, capital and labor in case of Pakistan. The findings show that both renewable and nonrenewable energy consumption add in economic growth. Capital and labor are also important determinants of economic growth. The VECM Granger causality analysis validates the existence of feedback hypotheses between renewable energy consumption and economic growth, nonrenewable energy consumption and economic growth, economic growth and capital.     

Exchange rate volatility–economic growth nexus in Uganda

The global financial crisis has disrupted trade and capital flows in most developing economies, resulting in an increased volatility of exchange rates. We develop an autoregressive distributed lag model to investigate the effect of exchange rate volatility on economic growth in Uganda. Using data spanning the period 1960–2011, we find that exchange rate volatility positively affects economic growth in Uganda in both the short run and the long run. However, in the short run, political instability negatively moderates the exchange rate volatility–economic growth nexus. These results are robust to alternative specifications of the economic growth model.     

Economic freedom–growth nexus in European Union countries

This study examines the economic freedom and economic growth nexus in a panel of 28 European Union countries. We investigate the relationship between growth and different components of economic freedom, measured in five major areas of the Economic Freedom of the World index. The aim of the article is to assess which aspects of economic freedom – and to what extent – contribute to economic growth in the EU. Our empirical analyses suggest that the results are sensitive to the method of estimation. Using the Generalized Method of Moments estimator which allows addressing endogeneity, we found a positive relationship between economic growth and four of the five aspects of economic freedom: security of property rights, quality of monetary policy, freedom to trade and regulatory policies.     

Non-linearity in the inflation–growth relationship in developing economies: Evidence from a semiparametric panel model

Using data on developing economies, we estimate a flexible semiparametric panel data model that incorporates potentially nonlinear effects of inflation on economic growth. We find that inflation is associated with significantly lower growth only after it reaches about 12 percent, which is notably lower than the comparable estimate obtained from a threshold model. Our results also suggest that models with restrictive functional form assumptions tend to underestimate marginal effects of inflation on economic growth. We also document significant variation in the effect of inflation on growth across countries and over time.

Inflation and the finance–growth nexus

This paper re-investigates whether there exist inflation thresholds in the finance–growth linkage. By applying the Caner and Hansen's (2004) instrumental-variable threshold regression approach to the dataset of Levine et al. (2000), we find strong evidence of a nonlinear inflation threshold in the relationship, below which financial development exerts a significantly positive effect on economic growth, while, above which, the growth effect of finance appears to be insignificant. Furthermore, we also find a positive and significant relationship between finance and productivity for inflation rates below the threshold level, but no such relationship is detected for inflation rates above the critical level. This result suggests that finance influences growth mainly through the productivity channel.     

Explosive bubbles in the US–China exchange rate? Evidence from right-tailed unit root tests

In this article we apply novel right-tailed unit root (sup Augmented Dickey-Fuller (SADF) and generalized sup ADF) tests to the China–US exchange rate. The empirical results document that the recent financial crisis in 2008 may be preceded by early warning signs of exuberance. Using the SADF test, evidence of an explosive behavior in the nominal exchange is found from 2005 onwards. This period coincides with both financial reforms in China and early indications of an impending US crisis that both have been reported in the literature. Our findings suggest that such an explosive behavior may be attributable to differences in the relative prices of traded goods. Policy implications are also derived.     

Non-linearities in inflation–growth nexus in the SADC region: A panel smooth transition regression approach

The main objective of central banks around the world is the achievement and maintenance of price stability, which actually creates an environment conducive for faster economic growth. Therefore, it is important for policy makers to understand the relationship between inflation and economic growth in order to make sound policies. If inflation is detrimental to economic growth, then policy makers should aim for low rates of inflation. This leads to a question; how low should the inflation rate be? Previous research in the non-linearities of the inflation–growth relationship has found that a positive relationship exists when the inflation rate is low and a negative relationship when the inflation rate is high. This implies the existence of a threshold level of inflation at which the sign switches. In this paper we use panel data for the period 1980–2008 to examine the inflation–growth nexus in the Southern African Development Community (SADC) region and to endogenously determine the threshold level of inflation. To deal with problems of endogeneity and heterogeneity, the paper uses the Panel Smooth Transition Regression (PSTR) method developed by González et al. (2005) to examine the non-linearities in the inflation–growth nexus. This technique further estimates the smoothness of the transition from a low inflation to a high inflation regime. The findings reveal a threshold level of 18.9%, above which inflation is detrimental to economic growth in the SADC region.     

Predictability within the energy consumption–economic growth nexus: Some evidence from income and regional groups

In re-examining the nexus between energy consumption and economic growth through the predictability framework, we adopt a panel data predictive regression model to examine the possibility of growth, conservative, feedback, or neutrality hypotheses for 135 countries. A predictive regression model is fitted to panels of countries on the basis of location and level of economic development. Findings suggest strong support for the neutrality hypothesis. A developing economy panel (90 countries) favours the conservative hypothesis, although a panel of 32 lower middle-income countries suggests that energy consumption per capita predicts real GDP per capita. These forecasts could provide future policy directions.     

Nonlinear dynamics and the exports–output growth nexus

The untested assumption of a linear relationship between exports and output growth in previous empirical investigations may lead to invalid inference if the actual relationship is nonlinear. This paper re-examines the relationship between exports and economic growth in five industrialized economies (Canada, Italy, Japan, UK, and the US) with emphasis on the effect of nonlinearities on the causal relationships. Results from linearity tests show that nonlinearities do exist in the dynamic relationship between exports and GDP growth. Nonlinear smooth transition autoregressive (STAR) model results suggest that nonlinear Granger causality flows from exports to output growth and vice versa. Predictive accuracy tests further confirm the appropriateness of the nonlinear models over the linear model specification.     

Are there bubbles in Chinese RMB–dollar exchange rate? Evidence from generalized sup ADF tests

This article uses recently developed generalized sup ADF (GSADF) unit root tests into the analysis of nominal RMB–dollar exchange rates bubbles. Based on the results from the GSADF tests, we find strong evidence of explosive behaviour in the nominal exchange rate and investigate two bubbles there. The first bubble is during 2005–2006 which is determined neither by the relative prices of traded goods nor the relative price of nontraded goods. The second bubble busts in 2008 during subprime crisis period, and which is determined by the relative prices of traded goods but not the relative price of nontraded goods. There is no bubble before 2005 as the exchange rate is under fixed regime. As for this result, some expansionary monetary and fiscal policies are required in China since these are the most efficient and effective under a bubble burst scenario.     

Earning functions in Portugal 1982–1994: Evidence from quantile regressions

This paper uses quantile regressions to describe the conditional wage distribution in Portugal and its evolution over the 1980s as well as the implications for increased wage inequality. We find that, although returns to schooling are positive at all quantiles, education is relatively more valued for highly paid jobs. Consequently, schooling has a positive impact on wage inequality. Moreover, this tendency has sharpened over the period. We also find that most of the estimated change in wage inequality was due to changes in the distribution of the worker's attributes, rather than to increased inequality within a particular type of worker. this version: January 2000     

Does corruption impede economic growth in Pakistan?

The present study reinvestigates the impact of corruption on economic growth by incorporating financial development and trade openness in growth model in case of Pakistan. We have used time series data over the period of 1987–2009. We have applied structural break unit root test to test the integrating order of the variables. The structural break cointegration has also been applied to examine the long run relationship between the variables.The long run relationship between the variables is validated in case of Pakistan. We find that corruption impedes economic growth. Financial development adds in economic growth. Trade openness stimulates economic growth. The causality analysis has exposed the feedback effect between corruption and economic growth and same inference is drawn for trade openness and corruption. Trade openness and economic growth are interdependent. Financial development Granger causes economic growth implying supply-side hypothesis in case of Pakistan.     

The tax–spending nexus: evidence from Romania using wavelet analysis

This article investigates the relationship between government revenue and expenditure in Romania between 1991 and 2015 using the wavelet approach. The article presents detailed information for different sub-periods and frequencies, emphasising the lead–lag nexus between variables under cyclical and anti-cyclical shocks. The main findings show that using individual taxation techniques under structural reforms should control short-term budget deficits. Separately, when an economic crisis arises, expenditure adjustment is a more appropriate fiscal instrument. In the medium and long term, the taxation system for individuals is recommended to be used to control for budgetary deficits during crisis. At the same time, in the medium term, government expenditures also represent a suitable policy choice.     

Does export variety determine economic growth in Pakistan?

This study explores the impact of export variety on economic growth in Pakistan. Export variety is decomposed into export related (within sector) and unrelated variety (between sectors) to examine the long run effect of export related variety and unrelated variety on economic growth. For this purpose, we incorporated export related variety and unrelated variety into the production function. The result of cointegration test shows that variables of the study are cointegrated in the long run. The result of fully modified ordinary least squares confirms the positive and significant effect of export related variety and unrelated variety on economic growth. Furthermore, the long run estimates show that the magnitude of export related variety is more than export unrelated variety. This study also finds the positive and significant effect of human capital on economic growth in the long run. It can be deduced from the results of the study that a specific sector shock will not disturb the economic pace of Pakistan.
