PurposeThe paper examined the relationship between financial development and economic growth for the period 1996 to 2018 in Eswatini.Design/methodology/approachThe Autoregressive Distributed Lag bounds test (ARDL) was employed to determine the long-run and short-run dynamics of the link between the variables of interest. The Granger causality test was also performed to establish the direction of causality between financial development and economic growth.FindingsThe ARDL results revealed that there is a long-run relationship between financial development and economic growth. The Granger causality test revealed bidirectional causality between money supply and economic growth, and unidirectional causality running from economic growth to financial development. The results highlight that economic growth exerts a positive and significant influence on financial development, validating the demand following hypothesis in Eswatini.Practical implicationsPolicymakers should formulate policies that aims to engineer more economic growth. The policies should strike a balance between deploying funds necessary to stimulate investment and enhancing productivity in order to enliven economic growth in Eswatini.Originality/valueThe study investigates the finance-growth linkage using time series analysis. It determines the long-run and short-run dynamics of this relationship and examines the Granger causality outcomes.

Brundtland Report

The papers that corporate governance have been examined are widely available in the literature. However, the studies which investigated the relationship between corporate governance and corporate sustainability is limited. Although corporate governance is reputed to some companies’ scandals such as Enron and Parmalat, corporate governance came into question with certain reports such as Cadbury and Hampel. But corporate sustainability conception spreads throught the World by Brundtland report more. The aim of this study is to explore whether there is relationship between corporate governance and corporate sustainability or not and to investigate the direction and strength of the relationship if there is a link. In this context, BIST XKURY and XUSRD indexes are used and Granger causality test is employed to study relationship between said variables. Results emphasize that there is a positively strong relationship between said variables and the causality relation is in two-way. Consequently, an overview has been demonstrated.Keywords: Corporate governance, corporate sustainability, shareholder, stakeholder, social responsibility

Purpose This paper aims to examine the validity of the question of whether oil dependence has a negative impact on the relationship between financial development and economic growth in Yemen. Design/methodology/approach The auto-regressive distributed lag approach for cointegration is used to examine the relationship between financial development and economic growth by capturing the impact of oil dependence on this relationship. The Granger causality test, based on a vector error correction model (VECM) framework, is used to investigate the causal relationships between financial development and economic growth. Findings The most interesting finding is the negative sign of interaction term between financial development and oil dependence, which implies that the positive effect of financial development on economic growth decreases with the increasing oil dependence. The result of the VECM Granger causality test revealed the existence of unidirectional causality running from financial development to economic growth. Research limitations/implications The short sample period and the worry of losing degrees of freedom limited us when including control variables in the model. If the data are available in the future, other control variables can be added. Practical implications The government should reduce the level of oil dependence in Yemen by diversifying the country’s economy. Accelerating the pace and efficiency of the financial sector will bear fruitful returns in this regard. The government could achieve this strategy by playing a more proactive role in encouraging the expansion of credit to enable the financial sector to provide a more efficient intermediary role in mobilizing domestic savings and channeling them to productive investments across various economic sectors. Originality/value This is the first study to examine the impact of oil dependence on the finance-growth nexus in Yemen. A new indicator for oil dependence is also proposed.

PurposeThe aim of this article was to analyze how the presence of the elements that constitute organizational links are related to sensemaking in a cooperative system of medical work.Design/methodology/approachA content analysis was conducted following interviews with the managers of the cooperative, which is a member of the Brazilian cooperative system and one of the largest in the world. This analysis enabled the systematization of the categories that were identified through the coding of responses, aided by Atlas.ti 8.0 software.FindingsAfter the analysis, it was possible to resize the constitutive elements identified in the specialized literature into three categories: identification, cooperation and recognition. The proposed resizing does not preclude the presence of the constitutive elements identified in the analysis, but it evidences the presence of these elements in a contextualized manner, suggesting a model of an organic organizational link that is dependent on the relationship between subject–object (organization), in which the different perceptions of meanings affect identification, and this can strengthen or weaken the link in a constant process of resignification.Originality/valueWith regard to its theoretical relevance, the work helps to bring concepts related to organizational links and sensemaking closer together as a process in the realm of intersubjectivity. This provides evidence of the presence of constituent elements of ties in a contextualized manner, demonstrating that the interpretation of managers aids sensemaking in a process of circularity and resignification.

The Relationship

This chapter examines the relationship between stock market indices of the biggest six economies of the European Union and BIST 100. In this context, this study used the daily time series regarding indices of DAX for Germany, CAC 40 for France, FTSE MIB for Italy, IBEX 35 for Spain, AEX for Holland, FTSE 100 for United Kingdom, and BIST 100 for Turkey from 2014 to 2018. To test whether there is a co-integration relationship among indices, Johansen co-integration test was used. Since a co-integration relationship was not found between series, causality relationship between the European stock market indices and Turkey was tested with Granger causality test by establishing standard VAR model. As a result, a unidirectional Granger causality relationship was found from DAX, FTSE 100, CAC 40, IBEX 35, and AEX to BIST 100 according to lag length 1 and 2. However, a unidirectional Granger causality relationship was only found from FTSE MIB to BIST 100 for lag length 1. For lag length 1 and 2, no causality relationship was found from BIST 100 to the selected European stock market indices.

This study entitled "Analysis of The Relationship Between Gross Domestic Product and Indonesian Exports (Granger causality test)”. This research was conducted because of the dualism of the theory between the two variables. In macroeconomic theory, the relationship between Gross Domestic Product is one of the similarities, because exports contribute to Gross Domestic Products on the demand side, while neoclassical trade theory emphasizes causality related to household production and assistance for exports.The purpose of this study is to determine the relationship between Gross Domestic Product and exports. This study uses several analytical methods: Unit Root Test, CointegrationTest, Granger Causality Test using the E-views program7 and using Quarterly data.The results of the estimation of this study are the estimation of the relationship in GDP and exports, or in other words the Gross Domestic Product affects Indonesia's exports. This is concluded based on the estimation results that can be seen from the statistical F value that is greater than the f-table (8.958205> 3.841466) on the Null hypothesis. GDP is not an Export Granger with a 95% confidence level. This means, GDP affects exports When GDP can affect the level of exports in the intervals of 2000 to 2012.Keywords:Gross Domestic Product(GDP), Exports, Granger Causality Test
