Abstract

A nurse home care scheduling system is described. The objective is to provide medical care at patients’ homes using the fewest number of nurses possible to deliver the required care. The heuristic scheduling system is easy to implement as a computerized adaptive system. As such, it is easy to use on a daily basis and easy to update as new data related to completed treatment and new requests are obtained. A case study illustrates the advantages of implementing such a system.

This study investigates the impact of the Russia–Ukraine war (2022) on the volatility connectedness between Egyptian stock market sectors.

Abstract

Purpose

This study investigates the impact of the Russia–Ukraine war (2022) on the volatility connectedness between Egyptian stock market sectors.

Design/methodology/approach

This study employs the newest dynamic conditional correlation (DCC)-generalized autoregressive conditional heteroskedasticity (GARCH)-CONNECTEDNESS approach to examine volatility connectedness in a sample of ten sectors in the Egyptian stock market, namely banks, education, food, healthcare, industry, information technology, real estate, resources, transportation and travel, ranging from February 1, 2019 to May 31, 2022.

Findings

The findings show that connectedness among the Egyptian stock market sectors varies depending on the time. The average dynamic connectedness measure among sectors in Egypt is 73.24%. This average was 85.63% during the Russia–Ukraine War (2022). The author also shows that the transportation sector is the most significant net transmitter of volatility in the remaining sectors during the Russia–Ukraine War (2022).

Practical implications

This study intends for policymakers to examine the co-movements, market variations and volatility spillover of stock markets, particularly during crises. Furthermore, the results help investors gain insight into diversifying the investors' portfolio assets to optimize profits.

Originality/value

To the best of the authors' knowledge, no study has investigated the implications of the war between Russia and Ukraine (2022) on sectoral interconnectedness within the stock markets in any country and discussion and empirical evidence from African countries are lacking. This study fills this gap in the literature. Additionally, the author uses the newest approach, the DCC-GARCH-CONNECTEDNESS approach, to describe the time-varying volatility spillover between economic sectors in Egypt.

This paper studies the political economy of the endogenous urban–rural divide in two dimensions: labor market and provision of public goods.

Abstract

Purpose

This paper studies the political economy of the endogenous urban–rural divide in two dimensions: labor market and provision of public goods.

Design/methodology/approach

This paper gives a dual-sector model endogenously depending on the consumption of public goods (club goods), the number of rural–urban migrants and the tax rate (transfer payments).

Findings

According to the research findings in this paper, the constraints on the participation of rural residents portray the rural residents' bargaining power, and in the game between the urban elites and the rural residents, tax rates depend on the preferences of the urban elites and the constraints urban elites and the rural residents jointly face. Therefore, the urban elites have to set tax rates deviating from the most preferred ones. The model in this paper can explain a series of empirical findings and yield new theoretical findings for empirical testing.

Originality/value

Significantly, the paper finds that the increase in agricultural productivity will lead to industrialization, accompanied by the disintegration of the dual-sector model. However, though the increase in industrial productivity can accelerate industrialization, it will further expand the urban–rural divide.

Abstract

Purpose

The construction sector (CNS) occupies a very unique position in any economy depending on whether developed or developing economy. The size and linkages of the CNS are expected to be high to help push or pull the economy from developing to developed economy through elaborate forward and backward linkages, a cardinal aim of developing economies. This paper aims to investigate the forward and backward linkages of the CNS in the Nigerian economy.

Design/methodology/approach

In contrast to the traditional input–output analysis to assess sectoral economic performance and production interdependence, this paper used econometric techniques, including unit root test, cointegration test and Granger causality test to analyze the data. Time-series data (TSD) for the study were extracted from United Nations Statistical Department database.

Findings

The result indicated that the CNS has low forward linkages but high backward linkages to virtually all the sectors of the Nigerian economy. Thus, the outputs of construction mainly satisfy the manufacturing and other activities.

Originality/value

The paper gives an insight into the construction on backward linkages but less extensive forward linkages. The paper recommends a massive local content development of sector to deepen backward and forward linkages and thus helps pull or push weak sectors out of stagnation.

Abstract

Purpose

This paper aims to examine the cycle of labour protests in Sweden, comparing the contentious actions of trade unions in public and private sectors over 40 years. Prior studies have focused on industrial conflicts or labour protests, but a long-term perspective on the broad protest repertoire across sectors is lacking. The goal is to test the argument of diversification of action repertoire and differences between the public and private sectors.

Design/methodology/approach

The authors apply the grievance and political opportunity theories of social movement research for explaining the cycles of labour protests and differences between sectors in Sweden over 40 years (1980–2020). The unique protest event data are combined with the official strike statistics. The research period includes the globalisation of the economy and two economic crises.

Findings

Although unions in both sectors have decreased protest mobilisation over time, private sector unions have resigned the most, whereas public sector unions continue to mobilise a diverse set of protest actions. Swedish unions have not replaced strikes with other protest repertoires. The open opportunities have allowed them to use various protests as part of “routine” operations.

Research limitations/implications

Protest event data are derived from newspapers, leading to an over-representation of large events in the urban areas. Future studies should combine data from newspapers with data about online protests.

Originality/value

By thoroughly examining all protest events mobilised by all trade unions in different sectors over 40 years (1980–2020), the paper presents a comprehensive analysis of the cycles of labour protest. The findings should interest industrial relations and social movement scholars.

The purpose of this paper is to explore the dynamic interdependence structure and risk spillover effect between the Chinese stock market and the US stock market.

Abstract

Purpose

The purpose of this paper is to explore the dynamic interdependence structure and risk spillover effect between the Chinese stock market and the US stock market.

Design/methodology/approach

This paper mainly uses the multivariate R-vine copula-complex network analysis and the multivariate R-vine copula-CoVaR model and selects stock price indices and their subsector indices as samples.

Findings

The empirical results indicate that the Energy, Materials and Financials sectors have leading roles in the interdependent structure of the Chinese and US stock markets, while the Utilities and Real Estate sectors have the least important positions. The comprehensive influence of the Chinese stock market is similar to that of the US stock market but with smaller differences in the influence of different sectors of the US stock market on the overall interdependent structure system. Over time, the interdependent structure of both stock markets changed; the sector status gradually equalized; the contribution of the same sector in different countries to the interdependent structure converged; and the degree of interaction between the two stock markets was positively correlated with the degree of market volatility.

Originality/value

This paper employs the methods of nonlinear cointegration and the R-vine copula function to explore the interactive relationship and risk spillover effect between the Chinese stock market and the US stock market. This paper proposes the R-vine copula-complex network analysis method to creatively construct the interdependent network structure of the two stock markets. This paper combines the generalized CoVaR method with the R-vine copula function, introduces the stock market decline and rise risk and further discusses the risk spillover effect between the two stock markets.

Abstract

Purpose

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.

Design/methodology/approach

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.

Findings

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.

Practical implications

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.

Originality/value

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.

Abstract

Purpose

The purpose of this study is to dissect the transport infrastructure performance, public spending in transport infrastructure development and the manufacturing sector in determining the transport sector energy consumption.

Design/methodology/approach

An analysis of transport energy consumption with the transport infrastructure performance, public spending in transport infrastructure and manufacturing sector output in India using annual data for the period 1987–2019. The study used the autoregressive distributed lag (ARDL) bounds test approach along with FMOLS, DOLS and canonical cointegration regression (CCR) methods.

Findings

The results of the ARDL bounds test provide evidence for the long- and short-run relationships among study variables. It evidenced that transport infrastructure performance reduces transport energy consumption by using FMOLS, DOLS and CCR methods. Furthermore, the inference of the positive impact of value added in the manufacturing sector on transport energy consumption validates the higher energy demand of the manufacturing sector from a mobility perspective.

Practical implications

The estimated finding of this study is expected to be contributing to policy-making discussions on transport infrastructure and manufacturing sector development in an emerging economy like India with insights on energy consumption.

Originality/value

To the best of the authors’ knowledge, this is the first study that integrates the impact of manufacturing sector output on transport sector energy consumption along with transport infrastructure performance and public investment in the transport infrastructure.

Abstract

Purpose

Every shock, starting from the banking sector reform in 1992 to the global crisis due to Covid-19 pandemic, affects the performance of banks. The shocks and transformations jeopardise the bank’s performance. This study cover period of 30 years starting from 1992. So, the reason behind taking only public sector banks is that after 1991–92 many banking sector reforms took place, and many new private sector banks and foreign sector banks entered into competition due to the liberalization, privatization, globalization (LPG) policy. So, it has been difficult for public sector bank to manage their performance in a competitive market. So, the purpose of this study is to find out influencing factors of bank performance especially public sector bank, because, it has been vital to identify factors influencing their performance.

Design/methodology/approach

The current study explores the determinant of the performance of public sector banks in India. Currently, in India, 12 banks are public sector banks, which capture 59.8% market share in the banking industry. After 1994 new licences were issued by Reserve Bank of India for many banks, and foreign sector banks entered the market as an effect of LPG policy, and market competition is one of the significant determinants of the performance of banks. Thus, the panel regression model is used to analyse the impact of various determinants on the performance of public sector banks (from 1992 to 2021). Return on equity and return on assets are used as indicators of performance, whereas influencing factors are divided into two parts, bank-specific factors, which include bank size, asset quality (AQ), liquidity, credit deposit ratio (CDR), capital adequacy, debt-equity ratio, employee’s productivity and macroeconomic factors which include inflation rate, tax rate and gross domestic product (GDP).

Findings

Results of the study show that bank size is not an essential factor for measuring bank performance because it is insignificant with both indicators of performance. AQ, liquidity ratio and CDR are significant in both models with negative impact. Macroeconomic factors like GDP are insignificant with both indicators with positive relations and tax rates are significant with a positive relationship. The inflation rate is significant but affects negatively to performance.

Research limitations/implications

This study only focuses on public sector banks. So, the results for private and foreign sector banks might differ. Considering the larger market share compared to other sector banks, the authors are focusing on public sector banks only. Foreign banks and cooperative banks are not included current analysis because of huge numbers and different working environments.

Originality/value

Determining influencing factors of bank performance is crucial because it will help the bank take various policy implications and formulation. Since independence measuring bank performance are important area.

Abstract

Purpose

This article examines dynamic volatility spillovers between stock index returns of four main hospitality sub-sectors in US during the coronavirus disease 2019 (COVID-19) pandemic. These are tourism and travel, hotel and lodging, recreational services and food and beverages. Volatility spillovers are explicitly used as accurate and informative proxies for risk contagion between sectors during turbulent times.

Design/methodology/approach

The authors employ dynamic conditional correlation-generalized autoregression heteroskedasticity (DCC-GARCH) and wavelet coherence analysis (WCA) to analyze the phenomenon. The authors’ timeframe is divided into three main sub-periods, namely the pre-pandemic, the first wave and the second wave periods.

Findings

This study’s results reveal immense negative shocks in returns of all four sub-sectors on the Black Monday (8th March 2020). Moreover, high volatility persistence was observed during both waves with an exception of tourism and travel which exhibited lower volatility persistence during the second wave. The authors discovered magnified contagion effects between tourism and travel, hotel and lodgment and recreational services during the first wave of the pandemic with tourism and travel being the main volatility transmitter. Lower magnitudes of spillovers were observed between food and beverages and other sub-sectors with a decoupling effect being evident during the second wave.

Research limitations/implications

This study’s findings contribute to the contagion theory by providing evidence of disproportional volatility spillover among hospitality sub-sectors despite being exposed to similar turbulent economic conditions.

Practical implications

Crucial implications can be drawn from this study’s findings to assist in risk management, asset valuation and portfolio management. The importance of close monitoring, safety measures, international diversification and adequacy of liquid assets during health crises cannot be stresses enough for hospitality firms. Retail investors, speculators and asset managers can take advantage of this study’s findings to design trading strategies and hedge against risk.

Originality/value

A body of knowledge pertaining to effects of crises such as COVID-19 on hospitality stocks has been proliferating. Nonetheless, there is still a relative dearth of empirical literature on volatility spillover between hospitality sub-sectors especially during periods of rising economic uncertainties.
