Exchange rate, monetary policy rate (otherwise known as the central bank rate in Kenya), inflation rate, crude oil price and credit rating were used as the traditional cross-border investment vehicles while capital market performance was proxied by All Share Index. Ex post facto research design was used in a multiple regression analysis framework to determine the partial effects of the endogenous variables on the explained variable. Pretesting was done using the Augmented Dickey-Fuller method to establish the stationarity of the model variables.  The test showed that the data series were of mixed order of integration which necessitated the application of the Autoregressive Distributed Lag (ARDL) model. The ARDL bounds test indicated that the influence of traditional cross border investment vehicles on the performance of the Nigerian and Kenyan Capital markets was bound by a long-run relationship. Specifically, the long-run estimates showed that, whereas the Nigerian capital market was significantly affected by the dynamics of exchange rate and monetary policy more than Kenya, the Kenyan capital market was affected the most by the crude oil price changes and inflation than Nigeria. In terms of credit rating, the Nigerian capital market was largely negatively affected whereas Kenya seemed less volatile. Regarding the speed of adjustment to disequilibrium, it was observed that all the models exhibited an automatic adjustment to equilibrium after very short-run shock. The study concluded that traditional cross border investment vehicles had huge impact on the performance of the two markets and therefore recommended among others that, all the stakeholders should make concerted efforts towards improving the investment climates of East and West African leading stock markets.","PeriodicalId":73720,"journal":{"name":"Journal of economics, trade and marketing management","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89848690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stock market plays an important role in economic development and growth by creating liquidity and allocation of resources to deficit sectors of the economy. The study used the ARDL-ECM in the determination of the relationship between the two variables, using data for the period 1990 to 2020. Eviews Version 9.0 Statistical Package was used to run the regressions. This study found that Diaspora Remittances have an insignificant negative relationship with Stock Market Development for Zimbabwe. This may have been due to Diaspora Remittances flowing through informal channels and, therefore, may have not be tapped on for Stock Market Development. The study recommend an inclusive framework that allows the government to take measures to boost investor confidence, to encourage the diaspora population to invest more in Zimbabwe through elimination of corruption, having stable political environment, formulation of policies that ensures stability in the macroeconomic environment, and having the right governance systems. Encouraging campaigns which must be run by the government and nongovernmental organizations educating Zimbabweans in the diaspora of the benefits of investing home. Allowing the government to set up formal diaspora remitting channels which have minimal charges to encourage more remittances to flow through the channels. Government must also offer favourable interest rates on bond holders so as to lure those in the diaspora to invest in the stock market.","PeriodicalId":73720,"journal":{"name":"Journal of economics, trade and marketing management","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90068942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The past performance of a fund is not always indicative of its future performance, but it is the only quantitative way to judge how good a fund is at present. Investors always prefer funds which give high returns and have low risk. Thus while building a fund portfolio the fund manager should understand the impact of portfolio allocation in different instruments on the performance of the portfolio. The objective of the present study was to find the short-term effects of portfolio allocation on the performance of mutual funds. The data for the study consisted of the portfolio allocations and the performance measures of a sample of one hundred and nineteen open-ended mutual fund schemes, of which thirty-eight were diversified debt/ income funds, forty-eight were diversified equity funds, twenty-one were balanced funds, and twelve were short-term debt funds. The performance measures used for the analysis were: mean returns, standard deviation in returns, beta, and Sharpe ratio. The portfolio allocation of the funds was described both in terms of the percentage allocated in equity, debt, and cash & equivalents, and in terms of the percentage allocated in different sectors. The data was entirely secondary data, and was collected from the AMFI website. The findings of the study indicate that, for different types of funds, allocation in different asset classes, that is, equity, debt, and cash & equivalents, as well as their sector-wise allocation tend to impact the performance of the fund.","PeriodicalId":73720,"journal":{"name":"Journal of economics, trade and marketing management","volume":"37 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75981571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nearly, all cement industries have struggled with many problems over the last decade because of the unstable political situation, that negatively affects the Libyan economy. This research seeks to explore the development of the current industry sector in Libya, focusing in cement manufacturing, and assesses recent efforts to attract further foreign development. It sheds the light on the importance of logistics cost, as a factor in increasing the production capacity of the cement industry. Furthermore, to understand the significance of this subject, it provides an assessment of improving the capacity of cement manufacturing products in Libya through the “logistics strategy”. A survey was conducted among the target companies. The analysis of the survey responses indicates that, the management body within the surveyed companies has a modest strategy in most areas, which are considered very crucial for any level successful implementation of new strategies.","PeriodicalId":73720,"journal":{"name":"Journal of economics, trade and marketing management","volume":"54 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90757729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When the economy is not doing well, prompted by calamities like Covid-19 or occasioned by ordinary life cycles, individuals seek to migrate seeking job opportunities that pay better, enabling them to save for investment, eventually increasing welfare. Economic entities left at home continue to look for ways of mobilizing savings for growth. This article proposes analytic solutions to the labour migration and national savings problem by determining activation rationality pay-off, the labour migration rationality threshold and computing national savings using the income consumption rationality function deriving from the entropy rationality model – a behavioural framework that determines economic rationality exercised by an economic agent on a percentage scale. It is hoped that the proposed analytic solutions will be found useful by especially labour migrants and labour policymakers in this exponentially global growing society.","PeriodicalId":73720,"journal":{"name":"Journal of economics, trade and marketing management","volume":"50 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84549650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
