Abstract This study aimed to investigate the effects of social network propaganda on exchange rate and also exchange rate fluctuations on Iran economic growth. This study uses annual data to analyse the long-run and short-run relationship between variables for the period of 1993–2018. Data were collected from the Central Bank of Iran. The autoregressive distributive lag (ARDL) method proposed by Pesaran, Shin, and Smith (2001) was used. The results of long-run analysis show that a 1% increase in negative propaganda of social media about the exchange rate leads to a 3.8% decline in long-run economic growth. Also, a 1% increase in exchange rate fluctuations results in a 3.5% decrease in economic growth. Research findings also indicate negative short-run impacts of social networks on the excitement of the foreign exchange market and, ultimately, on economic growth.

As the Chinese government has been trying to promote the Belt and Road Initiatives and enhance the openness of its economic development, it is important to study and understand the depreciation/appreciation mechanism of Chinese yuan (CNY), especially how this affects or is affected by some key economic growth and openness measures like gross domestic product (GDP) and foreign direct investment (FDI). This paper is just to examine the short-run dynamics and long-run equilibrium relationships among the three important macroeconomic time series of CNY exchange rate, FDI and GDP. Twenty-year annual data from 1996 to 2015 for the top ten cities (in terms of GDP) in Guangdong, one of the economically influential provinces in China, are specifically collected for the study. The panel unit-root test, Johansen-Fisher cointegration test, Granger causality test, and vector autoregression (VAR) model are applied to analyze the data for exploring long-run relationships. Vector error correction (VEC) model and block exogeneity Wald test are also adopted to examine the short-run dynamics. Key research results include that, there is a long-run cointegration relationship among exchange rate, FDI and GDP, FDI and GDP are the long-run Granger causes of exchange rate such that FDI positively affects exchange rate whle GDP negatively influence exchange rate, and FDI is also the short-run Granger cause of exchange rate but the short-run relationship is negative. Discussions, and policy implications and future research directions are presented finally.

This research is motivated to scrutinise the effects of real bilateral exchange rate fluctuation on China-Nigeria bilateral trade, taking into consideration volatility and third country’s bilateral exchange rate effect to determine their consequences. Due to its robustness in time series analyses, an ARDL approach to co-integration was used to determine the long-and short-runs effects. Both export and import were considered separately. Outcome revealed that Nigeria’s import from China responds negatively to real bilateral exchange rate increase just as it does to its volatility. Her export to China reacts positively on both front, most especially in the short-run. Japan was integrated as a third country in this research due to her competing presence in Nigerian market. Third country’s real bilateral exchange rate play prominent but negative role in China-Nigeria trade, and is mostly effective in the long-run. With the absolute value of the co-efficient of real bilateral exchange rate greater than one, depreciating the Naira against the Renminbi will tend to ameliorate the negative balance of trade Nigeria has with China. Finally, democratic regime was found to be very essential in enhancing international business.

This paper examined the impact of Exchange Rate Management on economic growth in Nigeria between 1980 and 2015. The study was set to gauge how the management of exchange rate in Nigeria has impacted the economy. The study employed the Ordinary Least Square (OLS) method in its analysis. Co-integration and Error Correction Techniques were used to establish the Short-run and Long-run relationships between economic growth and other relevant economic indicators. The result revealed that exchange rate management proxy by various exchange rates regimes in Nigeria was not germane to economic growth. Rather, government expenditure, inflation rate, money supply and foreign direct investment significantly impact on economic growth in Nigeria. It is against this backdrop that the Nigerian economy must diversify her export base to create room for more inflow of foreign exchange.

The purpose of the paper is to see if there is any relationship exist between free floating exchange rate and export performance of Bangladesh. It inspects the monthly data of exchange rate and export value for the time period between year 2000 and 2017. It utilized the Johansen [1] cointegration approach to identify the extent of long run and short run relationship between them. The study could not establish neither any long term trend nor any short term dynamics between the variables. Respective variables are significantly related to their own immediate past values. Distant past values do not have any implications. This study suggests that short run macroeconomic policy would be beneficial to influence the foreign exchange market and eventually the performance of export of Bangladesh.

This paper highlights the role of higher education for the economic growth inPakistan. We explore the impact of increase in enrolment at tertiary level on thegrowth rate of income per worker. Estimating a growth model developed byMankiv et. al. (1992), using the annual data of Pakistan, we find a robustrelationship between higher education and economic growth in the long run. Themodel has also shown that investment in fixed capital has positive impact oneconomic uplift. Applying Johansen’s cointegration test, we show that the longrun elasticity of income with respect to capital stock is different from its share inGDP, and increase in the enrolment per unit of effective worker helps inbolstering economic growth. But, like earlier literature we also find statisticallyinsignificant relationship between higher education and GDP per worker. Thereare some fundamental reasons concerning to the ambiguous impact of investingin human capital on economic growth, particularly in the short run in case ofPakistan. First, the sharp increase in enrollment, recently, has been damaging thequality of education. Second, the unequal distribution of educational services hasheld back the efficiency of public expenditures, particularly before the reformsundertaken by higher education commission. Third, the low private return ofeducation has limited the demand for higher education in Pakistan for almost fiftyyears.

AbstractOne of the contending issues in Nigeria in the recent time is external debt and exchange rate fluctuations. In view of the above, this study examined the relationship between external debt and exchange rate fluctuations in Nigeria over the period of 1981 to 2018. Consequently, the study employed Autoregressive Distribution Lag Model to address the objective of the study. The major findings that originated in this paper are as follows: external debt, debt service payment and foreign reserve have a significant positive impact on exchange rate fluctuations in the short run in Nigeria. Furthermore, based on these findings, recommendations are made for the policy makers that external debt as a means of financing budget deficit should be minimized if not totally discouraged in Nigeria because its servicing in particular and repayment put pressure on foreign exchange market in the short run and thereby leads to exchange rate fluctuations in terms of depreciation of naira in the country. Also, country’s foreign reserve should be strengthened through the implementation of aggressive export promotion policy in Nigeria.

Abstract This paper provides new evidence to contribute to the current debate on the relative impact of public and private investment on economic growth and the crowding effect between the two components of investment in South Africa. Using annual data from 1970 to 2017, the study applies the recently developed Autoregressive Distributed Lag (ARDL)-bounds testing approach to cointegration. The study finds that private investment has a positive impact on economic growth both in the long run and short run, while public investment has a negative effect on economic growth in the long run. Further, in the long run, gross public investment is found to crowd out private investment, while its infrastructural component is found to crowd in private investment. The results of the study also reveal that both gross public investment and non-infrastructural public investment crowd out private investment in the short run. Overall, the study finds private investment to be more important than public investment in the South African economic growth process and that the importance of infrastructural public investment in stimulating private investment in the long run cannot be over-emphasized.

This article aims to understand the effects of exchange rate movements on economic growth in Bangladesh. Using a suitable analytical framework to derive an empirical specification, we construct a real exchange rate series and employ cointegration techniques to determine the output response to Bangladeshi currency depreciations. Our results suggest that in the long run, a 10 per cent depreciation of the real exchange rate is associated with, on average, a 3.2 per cent rise in aggregate output. However, a contractionary effect is observed in the short run so that the same magnitude of real depreciation would result in about a half per cent decline in GDP. While the long-run expansionary effect of real depreciations may be appealing for considering exchange rate policy as a development strategy, the likelihood of rising inflationary pressures needs to be kept in mind while pursuing this policy option.

This paper investigates, using annual data from 1980 to 2014, whether adoption of information and communication technologies (ICT) fosters economic growth in Indonesia. We employ an Autoregressive Distributed Lag cointegration technique on an augmented neoclassical growth model. The empirical results indicate a positive effect of ICT development on economic growth in both the long-run and short-run. The other regressors, such as total factor productivity, human capital, and capital per worker, also positively affect economic growth. From a policy perspective, the Indonesian government should promote ICT development through greater investment.

This study examines the link between unemployment and violence by controlling for income and security expenditure as an antidote to reduce violence in Nigeria. Violence claims many lives and properties in the country, which further increased the demand for public security as tax on the nation’s resources. Also, the increased unemployment in Nigeria, deserving urgent attention to be reduced, as literature has pointed out, causes idleness, deception, frustration and anger. The idea of criminal motivation and strain as an inducement to violence are supported by evidence. Considering the nature of the variables in this study, we tested for endogeneity by using annual data set from 1980 to 2015 before proceeding to test for the long-run and short-run relationship. The Bound Test used to test the cointegration while the Autoregressive Distributed Lag Model (ARDL) approach was used to conduct endogeneity test. ARDL Instrumental Variable is also employed to determine long-run and short-run estimates. The results showed that unemployment causes violence while income as a variable to economic growth reduces violence at the 1% level of significance. Similarly, the deterrence variable of security expenditure adversely affects violence at the 10% level of significance. Therefore, this study suggests policy to promote economic growth as the means of income-employment generation among the youth and the unemployed. Youth programs should be provided especially among the unemployed by granting credit facilities to finance their own projects and further strengthen the deterrence institutions. RESUMEN Este estudio examina el vínculo entre el desempleo y la violencia mediante el control de los ingresos y el gasto de seguridad, como un antídoto para reducir la violencia en Nigeria. La violencia se cobra muchas vidas y propiedades en el país, lo que aumenta aún más la demanda de seguridad pública, traducida como un impuesto a los recursos de la nación. Además, el aumento del desempleo en Nigeria, la cual merece una atención urgente que se reduzca ya que, la literatura señala, provoca ociosidad, engaño, frustración e ira. La idea de la motivación y la tensión delictiva como un incentivo a la violencia está respaldada por la evidencia. Teniendo en cuenta la naturaleza de las variables en este estudio, probamos la endogeneidad mediante el uso de datos anuales de 1980 a 2015, antes de proceder a la prueba de la relación de largo y corto plazo. El Bound Test se usó para probar la cointegración, mientras que el enfoque del Modelo de retardo distribuido autorregresivo (ARDL), se usó para realizar pruebas de endogeneidad. La variable instrumental de ARDL también se emplea para determinar estimaciones a largo y corto plazo. Los resultados mostraron que el desempleo causa violencia; mientras que el ingreso, como variable del crecimiento económico, reduce la violencia, al nivel de significancia del 1%. De manera similar, la variable de disuasión del gasto en seguridad afecta adversamente la violencia, al nivel de significancia del 10%. Por lo tanto, este estudio sugiere una política para promover el crecimiento económico como el medio de generación de empleo-empleo entre los jóvenes y los desempleados. El empoderamiento de la juventud debe proporcionarse especialmente entre los desempleados mediante la concesión de servicios de crédito para financiar proyectos propios y fortalecer aún más las instituciones de disuasión.
