We document how inflation expectations evolved in the United States during the fall of 1933 using narrative evidence from historical news accounts and the forecasts of contemporary business analysts. We find that inflation expectations, after rising substantially during the spring of 1933, moderated in the fall in response to mixed messages from the Roosevelt Administration. The narrative accounts and our econometric model connect the dramatic swings in output growth in 1933 – the rapid recovery in the spring and the setback in the fall – to these sudden movements in inflation expectations.

This study investigated the gender wage gap in Nigeria by analysing two waves of household surveys (in 2003–2004 and 2018–2019) in order to understand the dynamics or polarisation of the labour market in Nigeria in terms of the gender wage gap over time.

The study applied an extension of Oaxaca–Blinder decomposition that relies on the re-centred influence function (RIF) regressions to analyse the gender wage gap at all points along the wage distribution.

The results unambiguously show that there is a significant gender wage gap in Nigeria at all points along the wage distribution, such that for the two surveys used and after nearly two decades, men still earn more than women. That is, the log wage difference between males and females is statistically significant at all points between the 10th and the 90th quantiles. In 2003–2004 period, the authors found that most of the wage difference was significantly accounted for by the wage structure effect, whilst the composition effect was negative and only significant at the bottom of the wage distribution. Since the 2018–2019 period, the authors found that there has been a visible change such that most of the gender wage gap is now accounted for by the composition effect at all points along the wage distribution. Another interesting finding is that there has been a general decline in the gender wage gap along the entire wage distribution, such that inequality was higher in 2003–2004 than in 2018–2019. This decline is bigger at the top than at the bottom of the wage distribution. The authors also found that, contrary to some of the studies on the wage gap, the raw gaps for the two surveys appear to show inverted U-shape, but the gap has fallen quickly since the 2018–2019 period. Thus, the authors found strong evidence of a “sticky floor” compared to a “glass ceiling” effect in both periods, and this becomes more pronounced over time. In terms of the contributions of individual covariates on gender pay gap in Nigeria, the authors found that urban residence, unionisation, education and occupation variables exhibit major influence. However, the effects of covariates on the composition and wage structure components of the wage gap have changed over time.

The major policy implication of these findings is that to address the gender wage gap in Nigeria, policy should focus more on how labour is rewarded and improving human capital for women.

This study is a novel paper in Nigeria that has investigated the gender wage gap in Nigeria by extending the focus of literature in three ways. First, the authors applied an extension of Oaxaca–Blinder decomposition that relies on the RIF regressions to analyse the gender wage gap at all points along the wage distribution. Second, the authors used sample selection bias to account for the non-randomness of participation in wage employment. And third, the authors applied similar analysis to two waves of household surveys (in 2003/2004 and 2018/2019) in order to understand the dynamics or polarisation of the labour market in Nigeria in terms of the gender wage gap over time.

The Bureau of Economics in the Federal Trade Commission has a three-part role in the Agency and the strength of its functions changed over time depending on the preferences and ideology of the FTC’s leaders, developments in the field of economics, and the tenor of the times. The over-riding current role is to provide well considered, unbiased economic advice regarding antitrust and consumer protection law enforcement cases to the legal staff and the Commission. The second role, which long ago was primary, is to provide reports on investigations of various industries to the public and public officials. This role was more recently called research or “policy R&D”. A third role is to advocate for competition and markets both domestically and internationally. As a practical matter, the provision of economic advice to the FTC and to the legal staff has required that the economists wear “two hats,” helping the legal staff investigate cases and provide evidence to support law enforcement cases while also providing advice to the legal bureaus and to the Commission on which cases to pursue (thus providing “a second set of eyes” to evaluate cases). There is sometimes a tension in those functions because building a case is not the same as evaluating a case. Economists and the Bureau of Economics have provided such services to the FTC for over 100 years proving that a sub-organization can survive while playing roles that sometimes conflict. Such a life is not, however, always easy or fun.

The editorials of the then-new Business Week during the 1929–1933 contraction offered sophisticated Keynesian policy prescriptions: against a laissez-faire response, against deflation, against balanced-budget fetishism, for monetary expansion. These editorials, which seem to have been largely forgotten, likely played a considerable role in the dissemination of Keynesian economics in the United States in the 1930s. This chapter reviews the editorials and their congruence with Keynes’s writings. The magazine’s archives, including surveys of their readers, suggest that the editorials were among the most read and most valued parts of the magazine. The magazine cultivated an elite executive readership at that time, so the editorials may well have been important in gaining business support for Keynesian policies in the early New Deal.

This paper aims to examine the prospect of utilising corporate social responsibility and entrepreneurship (CSRE) as antidotes for mitigating the incidences of poverty, insecurity and underdevelopment in Nigeria. The paper derives its theoretical foundation from the stakeholder, instrumental and legitimacy theories, which all justify the use of CSRE for actualisation of Triple Bottom Line (i.e. the social, economic and environmental concerns of business organisations).

The study used the quantitative research method relying on the use of secondary data published by institutional bodies. The quantitative method entail a systematic extraction of reliable data on corporate social responsibility (CSR), insecurity, poverty and development from the publications of Office of the Millennium Development Goals in Nigeria, CLEEN Foundation, National Bureau of Statistics and Central Bank of Nigeria, respectively. For missing years, the authors improvised using projections as well as proxies. The extracted data, which spanned a period of 13 years, were subjected to econometric tests using SPSS, on the basis of which informed conclusions were drawn.

The first econometric result indicates a negative relationship between gross domestic product and poverty. The second result indicates that there is a positive significant relationship between gross domestic product and total crime rate. The third result indicates that there exists a positive relationship between gross domestic product and unemployment rate. The fourth result indicates that there is a negative relationship between gross domestic product and industrial growth rate. The last result indicates that there is a significant positive relationship between gross domestic product and CSR.

The results of this research have macro-level application, hence the outcomes cannot be narrowed to any particular sector of the economy. A micro-level analysis across diverse sectors of the economy is recommended in future studies. The implication of this empirical research is that policymakers in the Nigerian private sector need to reinvent their CSR programmes as mechanisms for poverty eradication, entrepreneurship development (CSRE), dousing tension of restive youth, empowerment/support for security agencies for better crime prevention and for impacting on sustainable development.

In the face of dwindling financial resources in the treasury of governments, the reinvention of CSRE by private sector organisations as complementary mechanisms for combating social problems is becoming acceptable in both developed and developing nations. This paper therefore boldly recommends that policymakers reinvent CSRE as development mechanisms through a sound partnership between government, advocacy groups and business corporations in Nigeria.

The paper explicates that CSR can indeed be reinvented by corporations as part of their social concerns to their operating environment instead of leaving all social problems to governments.

The research lends credence to stakeholder, instrumental and legitimacy theories of CSR. It also justifies the plausibility of CSRE, a novel concept being promoted in this research.

The purpose of this paper is to optimise the cost‐based performance of a tubular linear generator and to minimise cogging forces.

Optimisation of a tubular linear generator with longitudinal flux topology has been undertaken using a finite element method. The computational models used have been verified experimentally.

The use of an oversized stator linear generator design as opposed to an oversized translator design has the potential to increase the output electromotive force per unit material cost by 25 per cent for slotless iron core topologies and approximately 14 per cent for air core topologies. For cogging force minimisation, optimisation of the length of the stator core is an effective technique for both oversized stator and oversized translator constructions. Comparisons of magnet materials also indicate that the higher cost of rare earth magnets to ferrites is compensated by their superior specific performances.

In this paper, a broader range of design parameters than in previous investigations has been optimised for the slotless iron core and air core topologies. The result relating to cogging force reduction and cost savings (in particular) has the potential to make direct drive wave energy extraction a more competitive technology in terms of reliability and cost.

This study aims to assess financial development and debt status impact on energy efficiency in Nigeria as a developing economy.

This study combined the autoregressive distributed lag (ARDL), fully modified ordinary least squares and canonical cointegration regression analytical methods to estimate the parameters for energy efficiency policy recommendations. Secondary data between 1990 and 2020 were used for the analysis.

The result confirms the long-run nexus between energy efficiency, financial development and total debt stock. Furthermore, the ARDL estimates for this study’s key variables show that financial development promotes energy efficiency in the short run but hinders long-run energy efficiency. Total debt stock limits energy efficiency in Nigeria in short- and long-run periods.

The limitation of this study is that the scope is limited to Nigeria as a developing economy. The need to support energy efficiency projects is a global call requiring cross-country analysis. Despite this study’s focus on Nigeria, it provides useful insights that can guide energy efficiency policy through the financial sector and debt management.

The financial sector must ensure the availability of long-term credit facilities to clean energy investors. The government must maintain a sustainable debt profile to pave the way for capital expenditure on clean energy projects that promote energy efficiency.

The environmental consequences of energy intensity are being felt globally, with the developing countries most vulnerable. The cheapest way to curb these consequences is to promote energy efficiency to reduce the disastrous effect. Driving energy efficiency requires investment in energy-efficient technology but the challenge for developing economies, i.e. Nigeria’s funding, remains challenging amid a blotted debt profile. This becomes crucial to investigate how financial sector development and debt management can accelerate energy-efficient investments in Nigeria.

Purpose: This chapter explores the strategic role of human resource development (HRD) as a function of talent management (TM) and discusses how HRD activities can help to facilitate more creative behaviours, in the international hospitality industry.

Approach: We focus on TM and HRD research exploring how these lenses are conceptually positioned given our current knowledge on creativity. We draw on the system-based approach to creativity and reconceptualise the creativity components by levels of flexibility/plasticity and outline how such approaches can help creative practice development.

Findings: We rationalise the existing conceptual approaches to creativity and propose a simplified model considering the developmental aspects of creativity. First, we theorise the TM/HRD strategies, such as training and development via learning, as a mechanism to connect TM/HRD to creativity in the organisational setting. We inform the current literature on whether and how creative processes emerge at work and affect creative flow in the bottom-top and top-bottom directions. Second, we advance the development of creativity theory by reconceptualising the established creativity components by degrees of flexibility/plasticity. Such re-conceptualisation allows for more nuanced examinations of organisational stimuli (i.e. training and development) on developmental conceptions of creativity.

Originality: This is the first piece of work that has investigated the fit between TM/HRD and creativity research. Our conceptual model illustrates that creativity can be promoted and developed at work by incorporating developmental initiatives such as TM/HRD.

First, the effect of magnetic field intensity and nano-ferrofluid concentrations on surface roughness was evaluated in magnetic minimum quantity lubrication (MMQL). Then, the effect of lubricant flow rate and nozzle position on surface roughness was investigated in MQL, MMQL, electrostatic MQL (EMQL) and electromagnetic MQL (EMMQL).

This study examined the performance of MQL under magnetic and electric fields in turning AISI 304 stainless steel in terms of surface roughness and compared the results with those obtained from wet cutting and MQL turning operations. To prepare the nano-ferrofluid used in different states of MQL, Fe₃O₄ nanoparticles were added to the base fluid.

The results showed that the surface roughness under the EMMQL technique decreased by 36% and 49.4% on average compared with wet and MQL techniques, respectively. The lubrication technique affected the surface roughness by 90.2%, whereas it was 8.3% for the lubricant flow rate. EMQL and EMMQL techniques had no significant difference in their effects on surface roughness. In the innovative MMQL technique, the nano-ferrofluid concentration of 6% and magnetic field intensity of 93 G resulted in lower surface roughness of the workpiece relative to other counterparts.

Examining previously published studies showed that using nano-ferrofluids under a magnetic field for cooling purposes in machining processes have less considered by researchers. This study applies an innovative method of lubrication under the concurrent effect of magnetic and electric fields, called EMMQL, to improve the efficiency of MQL in machining hard-to-cut materials. For comprehensively inspecting the newly presented method, the effects of several parameters, including the nano-ferrofluid concentration, magnetic field intensity, lubricant flow rate and position of lubricant spray nozzle, on the surface roughness of workpiece in turning of AISI 304 stainless steel are investigated.

The reason for concern is the rapid decline in loans to small enterprises which is critical to their performance, compared to large businesses following the periods of banking reformations in Nigeria. Thus, the purpose of this paper is to investigate the influence of risk perception on bank lending behaviour to small enterprises. It also investigates the impact of government intervention, consolidation and recapitalization on the relationship between risk perception and bank lending behaviour to small enterprise.

This study empirically analysed (ordinary least square) secondary data obtained from the Central Bank of Nigeria Statistical Bulletins, Annual Statement of Accounts covering the period 1992–2020.

The results show that the absence of government interventions and the presence of banking reformations have statistically negative significant effect on bank lending to small enterprises. The findings challenge the argument that generally assumes risk aversion of banks towards small enterprise lending because of small enterprise’s inability to prove their credit worthiness and consequently constraining access to finance to the sector. Instead, the results and analysis from this study found theoretical support for the variation of bank behaviour in lending to small enterprises depending on the status of wealth of the financial system.

A key lesson from this study for government concerned about promoting performance of the small enterprise sector is that regulating and enforcing lending requirements on access to debt financing of the sector is necessary if constraints in access debt finance is to be eliminated. Second, while strategies such as bank consolidation, recapitalization may help strengthen and make financially robust the banking system; it places the banks in a gain position where losses looms to them than gain.

This study challenges the argument that generally assumes risk aversion of banks towards small enterprise lending as a result of inability to prove their credit worthiness and consequently constraining access to finance to the sector. Instead, the results and analysis from this study reveal a variation in lending to small enterprises and suggests that the position of the bank in relation to a reference point influences how risk is perceived by the bank and thus impacts on their risk decision-making behaviour.
