Subject Terms: Hydroelectric plants/Electricity generation/Prices/Kenya Electricity Generating Company ;

Abstract:

The objectives of this study were to determine whether the availability of the KenGen Hydropower plants impacts on electricity consumer prices; to determine the general impact of the Power Purchase Agreements on the electricity consumer prices; and to interrogate the impact of liberalization in the electricity subsector on the electricity consumer prices. Primary data was collected by way of questionnaires which were administered to senior KenGen Management Staff while secondary data was obtained from Kenya Power and validated by the same data from Energy Regulatory Commission and KenGen. Primary data was analyzed using descriptive statistics while secondary data was analyzed using regression analysis model. One major finding of the study is that there is a negative relationship between consumer prices and Availability of the KenGen Hydropower plants. The study further demonstrated that Availability of the KenGen Hydropower plants does not affect the consumer prices. The use of the model developed to forecast the consumer electricity price is therefore not recommended as one might get predictions that are inaccurate. The study found that about 70 percent of KenGen's power generation consisting of hydropower was not a good strategy for consumers and KenGen needed to invest more in other energy sources. The study also emphasized that KenGen has the capacity and strategy to bring down electricity prices at the same time electricity prices would be lower if other independent producers also owned hydro power plants. This is also in line with the opinion of majority of the respondents that electricity prices would come down in the future.

Subject Terms: Strategic management/Airline industry/Price increases/Gasoline ;

Abstract:

The study sought to determine the strategic responses by Kenyan airlines to the changes in the price of aviation fuel. It further investigated whether Kenyan airlines had adopted financial and/or non financial strategies, the extent to which these strategies had been implemented and the level of success that they had with these strategies in responses to the changes in the price of aviation fuel. The study was based on a census of the six airlines operating in Kenya. The respondents of the study were the Finance and Flight Operations managers in the respective airlines. A semi structured questionnaire was applied as the data collection tool which contained a mix of open-ended and closed-ended questions. Data was analyzed through the use of The Statistical Package for Social Sciences (SPSS). It was observed that Kenyan airlines have adopted a number of strategies in response to the changes in the price of aviation fuel. These have been through fleet management decisions, weight reduction programs and modification of flight operations procedures. It was further observed that these strategies have been applied in differing degrees by the respective airlines with varying degrees of success based on the total savings achieved. The study suggests further research studies in the area of the air traffic management and different operational practices hold some prospect for reductions in fuel usage or mitigation of environmental effects of aviation.

Subject Terms: Rates of return/Stock prices/Nairobi Securities Exchange ;

Abstract:

The presence of the seasonal or January effect in stock returns has been reported in several developed and emerging stock markets. Over the last couple of decades, there has been a steadily growing interest in new and different forms of investment. The objective of this study was to investigate the existence of January effect on stock returns: evidence from Nairobi Securities Exchange. The target population for this study included 50 companies listed in the Nairobi Securities Exchange as at 31 December 2011. The study was carried out focusing on a period of ten years up to 2011. This study utilized secondary data. Data on the market share prices was obtained from the share prices as reported by N.S.E. Data collected was analyzed using simple linear regression and correlation analysis. The study concluded that January effect has no significant relationship with the stock returns at NSE. In particular the study established that although other studies find that volatility tends to be higher in January, this study fmds it to be period-specific and mostly in value-weighted return series, but not in equal-weighted return series. This is true for both the unconditional and conditional return volatility. The study findings indicate that there is no significant relationship between the mean monthly January Effect on stock returns and the mean monthly stock returns of February through December. Comparisons between our economy and other economies and stock exchanges to find out the reasons why the fluctuations are either positive or negative need to be done. A research on the macro-economic and other factors to find out the other causes of these fluctuations should also be done to shed more light on why there are these fluctuations.

Abstract:

Globalization is the ongoing social, economic, and political process that deepens and broadens the relationships and inter-dependencies amongst nations, their people, their firms, their organizations, and their governments. International competition involves the battle between businesses to win consumer acceptance and loyalty in the international field. As multinationals diversify through foreign direct investments in other countries, they are posing major threats to the local firms which in return have resulted to various tactics to ensure that their market share is not threatened by new entrants. This study was set to determine the effect of Multinational Chinese Firms in competition with the Local Firms in Kenya. The study was conducted on a sample of 15 Multinational Chinese Firms and 25 Local Kenyan Firms doing business in Kenya. Data was collected using questionnaires which were delivered to both Local firms and Multinational Chinese firms targeting middle level employees. The results were analyzed and the findings from the study indicate that Local Kenyan Firms are being adversely affected by the Multinational Chinese Firms in terms of pricing, quality and marketing of their products. To remain competitive, the local firms have resulted to price reduction thus affecting their profits, advertisement thus increasing their expenses and quality improvement thus a need for them to invest more in research and development. The findings of this study are important because they will assist in developing policies and strategies that will ensure that Local Kenyan Firms are able to compete successfully with the Multinational Chinese Firms in Kenya. This include as identified in the study, becoming more innovative, responding efficiently to customers' needs, developing affordable products, developing new & better quality attractive products and being proactive in coming up with competitive strategies to beat competition.

Subject Terms: Nairobi Securities Exchange ; Shares ; Stock prices ; Trade volume ;

Abstract:

This study intended to examine the price- volume movements in the NSE, in order to determine the impact of changes in trade volume on the volatility of stock prices. Traded volume is the , measure of how many trades take place for a security or on an exchange on a given trading day. A high trading volume is an indicator of a high level of interest in a security at its current price. The research design was a correlational study and the population of study consisted of all the 20 companies forming the NSE20 - share index by December 31, 2011. The sample consisted of 14 companies continuously forming the NSE 20-share index between the periods January 2007 - 3151 December, 2011. Secondary data for the period was collected from NSE data bank. Purposive sampling was used. The sample of. 14 was based on the factthat some companies such as Uchumi Ltd and CMC motors had been suspended while Athi River mining co, Safaricom and Equity bank were included in the index in 2008 and Kenol Kobil was removed from the index in 2009. Volume of shares was computed using the average monthly traded volumes while share price volatility was determined using the standard deviation. Karl pearson's correlation 00- efficient model was used for the purpose of analysis to determine whether there exist a relationship between the variables. A regression model was also used to further assert the outcome of the study. The T -tests were below 0.5 which was insignificant and the R2 also were below 0.5 indicating that major variations of price were explained by other variables other than changes in traded volumes. It was concluded that there is a weak correlation between traded volume and the share price volatility of listed firms at the NSE. It is however recommended that a study of similar nature to be carried out on all the listed companies to give a more varied and valid conclusion.

Abstract:

This paper examined the impact of cross-border listing on stock returns. The objective of the study was to establish the impact of cross-border listing on stock returns in the Nairobi Securities Exchange. This paper further examined the impact of cross-border listing on risk. The period covered was between 2001and 2011. The sample consisted of seven Kenyan firms which had cross-listed in the neighbouring stock exchanges between 2001and 2011. Event study methodology was used to analyze the impact of cross-border listing on stock returns. The study finds positive average abnormal returns around the date of the cross-border listing. The study also finds insignificant positive cumulative average abnormal returns around the cross-border listing date. The impact of cross-border listing on risk was found to be varied across the different sampled stocks. There are several other benefits associated with cross-border listing other than an increase in stock returns hence it should be encouraged in the region. Therefore, policy makers for both the country of primary listing (home country) and secondary listing (host country) need to come up with the right policies to encourage cross-border listing in the region. Some of these policies include: provision of incentives to companies wishing to cross-list, introduction of policy measures that encourage shareholder protection and transparency, improvement of the regional flow of information and coordination and communication infrastructure to facilitate cross-listings and harmonization of listing rules, accounting laws and disclosure requirements across the region.

Abstract:

Both cultivated rice species, Oryza sativa (L.) and Oryza glaberrima (Steud.), are grown in Africa. To take advantage of superior traits from each species, AfricaRice Center and partners developed inter-specific rice cultivars called NERICA (NEw RICe for Africa) for rain-fed upland ecosystems. NERICA rice cultivars showed different susceptibilities to both S. hermonthica and S. asiatica species under controlled environment conditions. Some cultivars showed good broad-spectrum resistance against several Striga ecotypes and species whilst others showed intermediate resistance or were very susceptible. In addition, some cultivars showed resistance to a particular ecotype of Striga but were susceptible to others. The phenotype of a resistant interaction was often characterized by necrosis at the host parasite interface and an inability of the parasite to penetrate the host root endodermis. In general, the most resistant NERICA cultivars grew better than the very susceptible cultivars although even a small number of parasites caused a reduction in above ground host biomass. There was however, genetic variation for tolerance to Striga (the ability to grow and yield well in the presence of Striga) amongst the NERICA cultivars. The NERICA cultivars were also grown in field trials at Kyela in Tanzania (under S. asiatica infestation) and at Mbita Point in Kenya (under S. hermonthica infestation) in 2010 and 2011 to determine the impact of environment on the expression of resistance. The resistance of the NERICA cultivars against S. hermonthica and S. asiatica, in the field, was broadly similar to that observed in the laboratory although there were some exceptions. These results allow us to recommend particular cultivars for Striga-infested regions but they also illustrate the necessity of understanding the genetic basis of resistance to different ecotypes of Striga for breeding of durable resistance (and pyramiding of appropriate resistance genes) in host cultivars adapted to different rice agro-ecosystems in sub-Saharan Africa. Sixty four lines of an inter-specific CSSL population and the parent cultivars O. glaberrima MG12 and O. sativa Caiapo were phenotyped for resistance to S. hermonthica. MG12 showed good resistance to S. hermonthica whilst Caiapo was very susceptible. The CSSLs showed a range of susceptibility to the parasite, however, only two CSSLs showed the same strong resistance phenotype as MG12. Graphical genotyping and a Quantitative Trait Loci (QTL) analysis revealed a large QTL on chromosome 12 (designated STR12.1) which explained at least 80 % of the variation for resistance in the population and suggests that resistance to S. hermonthica (in MG12) is due to one (or a few genes) of major effect. This finding opens the way for the identification of candidate Striga resistance genes (through fine mapping approaches) and their transfer to farmer-preferred cultivars via marker assisted breeding.

Subject Terms: Maize/Prices/Volatility ;

Abstract:

Volatility provides a measure of the possible variation or movement in the price of a commodity experienced over a given period of time and is measured using the standard deviation. In this study, volatility of maize prices for Kenya, Uganda, and Tanzania in comparison with the F AO Global prices for the period of January 2003 to August 2011 is estimated. The study employs measures of dispersion like unconditional standard deviation and the coefficient of variation together with a 20% band around the trend line compared with time series models, the ARMA and EGARCH. Maize prices in Kenya, Tanzania, and F AO Global were found to be time varying and thus estimated using the EGARCH model and the average unconditional standard deviation used as a measure of volatility. Volatility of Uganda maize prices was constant over time and was estimated using ARMA (1,1). Different from other studies that have investigated volatility of commodity prices in the region, we compare volatility as estimated by both measures of dispersion and time series models. The study shows that by both methods, maize prices in Uganda were the most volatile followed by Kenya, Tanzania and then F AO Global implying that volatility in the East African markets is high compared to the global maize market. The study finds time series models to be more appropriate in quantifying volatility than measures of dispersion because they account for the time varying pattern that is common in commodity prices and can be used to predict future volatility which can be used as a risk management tool. Key words: volatility, Maize Prices, ARMA, EGARCH
