Generation and distribution of the total factor productivity gains in US industries

This study estimates productivity gains and their distribution among inputs and outputs for 63 American industries over the period 1987–2012. Using the traditional surplus accounting method, the Total Factor Productivity (TFP) growth rates are divided into their price change components in order to determine the stakeholders who do or do not receive price advantages.

An initial analysis showed that TFP of US industries increased at an average trend of 0.8% and established that remunerations to employees and firms’ profitability constituted 49% and 39%, respectively, of the accumulated economic surplus from the productivity gains. Suppliers of intermediate inputs retained 12.1% of the surplus. Finally, customers, equipment and structure providers were the losers in the distribution of economic surplus via, respectively, a significant growth of relative final demand prices and a substantial price decrease of these assets.

A second step analysis underlined that industries with high TFP growth rates mainly benefited customers and firms via output price decreases and profitability improvements while industries with low or negative TFP changes hurt customers through significant output price increases. The sectoral level analysis also showed that employees’ remunerations depend only slightly on productivity gains produced within their industrial sectors.     

Effect of financial development on international trade in Africa: Does measure of finance matter?

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.     

Deceiving Our Minds: A Qualitative Exploration of the Money Illusion in Post-redenomination Ghana

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.

Why have freedom and the liberal economy declined in Africa since independence? Charles Mensah of the independent Institute of Economic Affairs in Ghana offers an economic explanation.     

Adjusted accounting beta,operating leverage and financial leverage as determinants of market beta: A synthesis and empirical evaluation

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.     

The influence of marketing communications strategy on consumer purchasing behaviour in the financial services industry in an emerging economy

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.
