The Impact

The main objective of this study is to analyze the impact of climatic variables (temperature and precipitation) on sorghum productivity in the Cercle of Koutiala in Mali. To do this, the model of the production function was used to estimate the variation of sorghum yield during a period of 30 years (1986-2015). After the test of the unit root of Dickey-Fuller Augmented (ADF), the estimation of the semi-logarithmic model by the Ordinary Least Square method (OLS) showed that the yield of sorghum was affected by the climatic variables. The increase in average rainfall over the period June-September positively affects the performance to a certain threshold. On the other hand, the average temperatures during June-July have no significant effects on the yield. The temperatures observed during August and September, negatively affect the performance of sorghum during the study period to a certain threshold. The precipitations of August and September have a positive impact but not significant on the yield. The interaction between mean precipitation and average temperature during the same period negatively influences the yield of the sorghum. Indeed, the increase of the precipitation combined with an increase of the temperature for the period June to September causes a reduction in the yield of sorghum. Depending on this situation, it is important and necessary to take measures to mitigate the negative impacts of climate on sorghum yield in the Cercle of Koutiala.

The Impact

<p><em>Research on the impact of migration on workers' wages in destination areas has long been debated in the literature. However, studies that link migration to wage rates in different percentiles along the distribution have not been widely implemented, as migration does not have the same impact on wage levels in all groups of workers. By establishing a counterfactual using the semi-parametric DFL method of National Labor Force Survey data, this study found that migration promotes changes in the distribution of wages, especially in the upper and lower percentiles. After controlling the magnitude of in-migration in each percentile group by using the ordinary least square method, this study also proves that migration leads to wage decreasing in percentile groups where migrant workers are overrepresented, which is in the 75th and 90th percentile groups. Meanwhile, no negative impacts were found on wage levels in the lower middle percentile. In fact, migration has proven to encourage an increase in the average wage of workers in the lowest percentile of the distribution.</em></p><p><strong><em>JEL Classification: </em></strong><em>J01, J11, J61</em><strong></strong></p><strong><em>Keywords</em></strong>: <em>counterfactual, migration, wage distribution</em>

Purpose The purpose of this paper is to examine the behavior of the stock market returns in the different days of the week and different months of the year in accordance with the Islamic calendar. Further, the study estimates the risk-adjusted returns to test the performance of the indices during the Ramadan and non-Ramadan days. Finally, the study investigates the impact of Ramadan on the returns and the volatility of the stock market indices in India. Design/methodology/approach Initially, the study applies the Ordinary Least Square method to test the day-of-the-week and the month-of-the-year effect of the common and Shariah indices. Next, the study employs the risk-adjusted measurement to examine the underperformance and over-performance of the indices for both the periods. Finally, the study estimates the GARCH (1,1) and GJR-GARCH (1,1) models to observe the impact of Ramadan on the returns and the volatility of the Shariah indices in India. Findings The study finds that an average return of the indices during the Ramadan days are higher than non-Ramadan days. Further, the average returns of the Shariah indices are significantly higher on Wednesday than other days of the week. In addition, the highest and significant mean returns and mean risk-adjusted returns of the indices during the Ramadan days are observed. Finally, the study finds an evidence of the Ramadan effect on the returns and volatility of the indices in India. Originality/value The study observes evidence that the Ramadan effect influences the Shariah indices, but not the common indices in the stock market of the non-Muslim countries. It indicates that the Ramadan creates the positive mood and emotions in the investors buying and selling activities. The study suggests that investors can buy the shares before Ramadan period and sell them during the Ramadan days to get an abnormal return in the emerging markets.

The research aims to analyze the impact of managerial overconfidence on corporate investment (investment scale, overinvestment and underinvestment) using companies listed in Indonesia’s Stock Exchange in 2012-2018 as a sample. The analysis method used Ordinary Least Square and robustness test used Maximum Likelihood  Estimation. The result shows that managerial overconfidence has a significantly positive impact on the corporate investment scale. It means that managerial overconfidence makes overinvestment problem more severe (more inefficient) and underinvestment problem less severe (more efficient).

This research examined the direct and indirect impact of taxation on the Nigerian economic growth. This research centered on two major objectives by focusing on the trend of direct and indirect tax and the impact of the Nigerian tax system on the growth of the economy.  The research adopted the descriptive research design.  The secondary source of data was also engaged as this data was from CBN statistical bulletin and the annual reports from 1994-2013. The research also used the ordinary least square regression technique. With the use of E-views 7.1 to analyze the data, the first objective was achieved by using graphical analysis while the second objective used ordinary least square regression analysis. The results reveal that the direct and indirect tax have a positive impact on the economy of Nigeria. Therefore, it is recommended that government should take advantage of taxation and promote tax system in Nigeria.

This study examines the impact of capital inflows on economic growth of developing economies; the case of Nigeria, Ghana and India from 1986-2012. This is necessitated by the doubts being raised as whether the huge inflows of foreign capital in developing economies over the years have transmitted to real economic growth. Augmented Dickey Fuller unit root test was employed to evaluate the stationarity of the data, while Johansen Co-integration was used to estimate the long-run equilibrium relationship among the variables. The casual relationship was tested using Granger Causality, and Ordinary Least Square method was used to estimate the model. The findings reveals that capital inflows have significant impact on the economic growth of the three countries. In Nigeria and Ghana, foreign direct and portfolio investment as well as foreign borrowings have significant and positive impact on economic growth. Workers’ remittances significantly and positively related to the economic growth of the three countries. The enabling environment should be created in the developing countries to encourage more inflow of foreign investments and workers remittances. This will help in closing the savings-investment gap and encourage economic growth in these countries. The study signifies that capital inflows is indispensable in closing the savings-investment gap required for economic growth of developing countries.
