This article reexamines and synthesizes two streams of research dealing with the relationship between market beta and accounting risk measures. It is shown that, with some minor rearrangement the Mandelker and Rhee (1984) model can be shown to be as a decomposition of the familiar accounting beta (Beaver, Kettler and Scholes 1970) into operating leverage, financial leverage, and an adjusted accounting beta. The adjusted accounting beta can be further decomposed into productivity gains and the relative cyclical sensitivity of the accounting flows of the firm. Empirical estimates of this extension made using three accounting flow measures in addition to earnings show that the intrinsic business risk factor not identified in the original Mandelker and Rhee model is the most significant explanatory factor related to market beta. 相似文献
A survey of contemporary literature suggests that empirical studies on developing economies are few or almost non-existent. Engle and Patton (2001, What good is a volatility model. Quantitative Finance, 1, 237–245) as well as Poon (2005, A Practical Guide to Forecasting Financial Market Volatility. New Jersey: Wiley.) suggest that a good volatility model is one that utilizes the empirical regularities of financial market volatility (of which most were observed on industrialized economies markets). This paper uses exchange rate series from Ghana, Mozambique and Tanzania to show that;
they are not different from other financial markets as they exhibit most of the empirical regularities including volatility sign asymmetry, non-normal distribution and volatility clustering. It is however observed that the three exchange rate series are very volatile, with induced volatile shocks highly persistent and asymmetric, and extreme prices commonplace;
the ARCH technique (which has been well documented to capture these empirical regularities and produce good forecasts) generally produced a good fit to the three exchange rate series when compared with volatility forecasts generated using the EWMA technique. In the simple analysis of a day-ahead volatility forecast abilities of estimated models, it was observed that best fit does not necessarily ensure best forecast.
The current study is a qualitative exploration of the presence of the money illusion in the lived experiences of Ghanaian
adult consumers after a currency redenomination. The results indicated that a switch from the old currency to the new currency
had implications for self-worth determination, trivialization of price increases, changes in spending behaviour, and changes
in the extent of benevolence. All these changes were related to the tendency to make judgments based on the nominal value
of an amount of money, rather than its real value; the judgment bias is known as the money illusion. 相似文献
This study conducts a survey among households in three cities in Ghana on how water delivery should be managed. The contingent valuation method was used to estimate the willingness to pay for improved water delivery under private sector participation. Results indicate that most households will remain connected to their current water supplies if private sector is engaged to improve water delivery at higher monthly water bills. Given that the mean household monthly water bill of GH¢10.82, the results indicate that there is demand for water quality improvement, and private sector engagement is likely to provide these services. However, this policy measure marginalises the poor in terms of access to water. Therefore, private sector participation in water delivery may require a complementary programme to promote access to water. 相似文献
Although improving international trade on the back of financial sector development is one of the preoccupations of countries in Africa, empirical literature on financial development-trade nexus has not been rigorous in examining how finance shapes trade. In this study, we examine the effect of financial development on international trade in Africa relying on data for 46 countries over the period 1980–2015. Results from our system generalized method of moments reveal differential effects of finance on trade. In particular, we notice that, private credit does not promote trade while domestic credit positively affects trade. These effects are robust to measures of trade. Thus, improving the level of private (domestic) credit dampens (amplifies) exports and trade openness. However, we also find a U-shaped relationship between private credit and trade measures suggesting that financial sector development may be detrimental (helpful) to trade for economies with low (high) level of private credit. 相似文献

The financial services sector is characterised by a high level of consumer perceived risk and irrational behaviour in decision-making, which is predominantly influenced by the effect of communication and the application of heuristics as a function of communication in consumer decision-making. This situation promotes marketing communication as one of the most essential activities that financial institutions rely on to mitigate the perceived risks and to satisfy consumers’ quest in understanding financial products. Hence the importance of this research is to establish the effects of marketing communication on consumer purchasing behaviour in emerging economies that are experiencing expanded financial markets but limited corresponding research insight. To achieve the aim of this study, the research uses data from 360 customers of selected financial institutions in Ghana. The hypotheses are tested using the structural equations modelling technique. The results of the study reveal marketing communication strategies evaluated have positive and significant impacts on consumer purchase behaviour. However, amongst the marketing communication strategies tested advertising and celebrity endorsement were found to have an insignificant relationship with consumer purchase behaviour. The study offers practical and theoretical insights into understanding the dynamics and nuances of the integrated marketing communication mix and how they influence the purchase behaviours of consumers.
We compute a time-varying metric of monetary policy credibility based on Ghana’s experience, using both symmetric and asymmetric approaches. We then follow-up with some empirical evidence to address the linkages between macroeconomic developments and central bank credibility. The empirical results reveal high and low credibility cycles with an average duration of 2 years over the study period. Particularly, higher levels of credibility were associated with stable domestic currency and lower nominal interest rates. This reinforces the notion that efficient monetary policy delivers higher central bank credibility with better outcomes for macroeconomic variables. In contrast, the level of credibility tends to worsen in the wake of weakening macro fundamentals which are not adequately countered by monetary policy decisions. There is therefore the need for efficient monetary policy formulation to achieve a stable macroeconomic environment in Ghana. This will in the long-run build policy credibility towards attaining the central bank’s medium-term inflation target. 相似文献
