  • Sensitivity of economic policy uncertainty to investor sentiment

    Rehman, Mobeen Ur; Apergis, Nicholas; University of Piraeus; University of Derby; Institute of Science and Technology Islamabad, Pakistan (Emerald, 2019-06-24)
    A series of global financial crises in 21st century, steep economic decline and slow recoveries have intensified the concern of regulatory bodies for economic policy certainty. This study explores the effect of investor sentiment on economic policy uncertainty (EPU), spanning the period 1995-2015. The analysis is carried out for Asian, Developed and the European market samples by applying the method of quantile regressions. The findings document the presence of a negative impact of investor sentiment on EPU. Robustness analysis illustrates the validity of the results for the cases of Asian and Developed markets.
  • Monetary policy and the gender pay gap: Evidence from UK households

    Apergis, Nicholas; Hayat, Tasawar; Kadasah, Nasser; University of Derby; King Abdulaziz University (Taylor & Francis, 2019-04-16)
    This paper studies how monetary policy decisions affect the gender pay gap across UK households through a survey database. The results signify the impact of monetary policy shocks on the gap; monetary authorities’ decisions carry welfare effects for households through their pay income.
  • Modeling the time varying volatility of housing returns: Further evidence from the U.S. Metropolitan condominium markets

    Apergis, Nicholas; Payne, James; University of Derby; University of Texas, El Paso (Wiley, 2019-04-22)
    This study extends the literature on modeling the volatility of housing returns to the case of condominium returns for five major U.S. metropolitan areas (Boston, Chicago, Los Angeles, New York, and San Francisco). Through the estimation of ARMA models for the respective condominium returns, we find volatility clustering of the residuals. The results from an ARMA-TGARCH-M model reveal the absence of asymmetry in the conditional variance. Dummy variables associated with the housing market collapse unique to each metropolitan area were statistically insignificant in the conditional variance equation, but negative and statistically significant in the mean equation. Condominium markets in Los Angeles and San Francisco exhibit the greatest persistence to volatility shocks.
  • Contagion across US and EU financial markets: Evidence from the CDS markets

    Apergis, Nicholas; Christou, Christina; Kynigakis, Jason; University of Derby; Open University of Cyprus; University of Kent (Elsevier, 2019-05-02)
    This study investigates whether contagion occurred during the recent global financial crisis across EU and US financial markets. The methodology used to test for contagion is the Forbes and Rigobon cross-correlation test, the Li and Zhu non-parametric test, the Fry et al. coskewness test and the Hsiao cokurtosis and covolatility tests. These tests are applied to a set of bank sector CDS, insurance sector CDS, sovereign bonds, equity and volatility indices. The findings indicate significant evidence of contagion, especially through the channels of higher order moments.
  • Convergence in condominium prices of major U.S. metropolitan areas

    Apergis, Nicholas; Payne, James; University of Piraeus; Benedictine University (Emerald, 2019-11-04)
    The purpose of the study is to examine the long-run convergence properties of condominium prices based on the ripple effect for five major U.S. metropolitan areas (Boston, Chicago, Los Angeles, New York, and San Francisco). Specifically, we test for both overall convergence in condominium prices and the possibility of distinct convergence clubs to ascertain the interdependence of geographically dispersed metropolitan condominium markets. Our analysis employs two approaches to identify the convergence properties of condominium prices: the Lee and Strazicich (2003) unit root test with endogenous structural breaks and the Phillips and Sul (2007; 2009) time-varying nonlinear club convergence tests. The Lee and Strazicich (2003) unit root tests identify two structural breaks in 2006 and 2008 with rejection of the null hypothesis of a unit root and long-run convergence in condominium prices in the cases of Boston and New York. The Phillips and Sul 92007; 2009) club convergence test reveals the absence of overall convergence in condominium prices across all metropolitan areas, but the emergence of two distinct convergence clubs with clear geographical segmentation: on the east coast with Boston and New York and the west coast with Los Angeles and San Francisco while Chicago exhibits a non-converging path. The results highlight the distinct geographical segmentation of metropolitan condominium markets, which provides useful information to local policymakers, financial institutions, real estate developers, and real estate portfolio managers. The limitations of the research is the identification of the underlying sources for the convergence clubs identified due to the availability of monthly data for a number of potential variables. The absence of overall convergence in condominium prices, but the emergence of distinct convergence clubs that reflects the geographical segmentation of metropolitan condominium markets raises the potential for portfolio diversification. Unlike previous studies that have focused on single-family housing, this is the first study to examine the convergence of metropolitan area condominium prices.
  • The relationship between investments in lean practices and operational performance: exploring the moderating effects of operational intellectual capital

    Onofrei, George; Fynes, Brian; Wiengarten, Frank; Humphreys, Paul; Prester, Jazna; University College Dublin (Emerald, 2019-05-03)
    Prior research has shown that operational intellectual capital (OIC) and investments in lean practices (ILP) lead to better operational performance. However, there has been no empirical studies on the synergetic effects between OIC components and ILP. More specifically, the question: can the efficacy of ILP be increased through OIC has not been studied. Accordingly, the purpose of this study is to report the empirical results of potential synergetic effects between operational intellectual capital (OIC), as a knowledge-based resource, and ILP. The empirical data used for this study was drawn from the fifth round of the Global Manufacturing Research Group (GMRG) survey project (with data collected from 528 manufacturing plants). The hypotheses are empirically tested using three ordinary least square (OLS) models. Our findings highlight the importance of leveraging a system of complementary knowledge based resources (OIC dimensions) and addresses the need for the reformulation of lean theory in terms of the emergent knowledge-based view (KBV) of the firm. The results facilitate greater understanding of the complex relationship between ILP and operational performance. Building on the contribution of Menor et al. (2007), we argue that OIC represents a strategic knowledge based resource that is valuable, hard to imitate or substitute and when leveraged effectively, generates superior operational and competitive advantage.From a managerial standpoint, this study provides guidelines for managers on how to leverage OIC to enhance the efficacy of ILP. We argue that firms consider investing in OIC to increase the return from ILP, which in turn will enhance their operational performance and provide competitive advantage. Our findings provide strong evidence of the importance of human, social and structural capital to enhance the efficacy of ILP. This is the first research paper that extends the application of intellectual capital theory in lean literature, and argues that the operational intellectual capital contributes to the efficacy of ILP. The analysis facilitates greater understanding of the complex relationship between OIC dimensions, ILP and operational performance.
  • Building routines for non-routine events: Supply chain resilience learning mechanisms and their antecedents.

    Scholten, Kirstin; Sharkey Scott, Pamela; Fynes, Brian; University College Dublin; University of Groningen; Dublin City University (Emerald., 2019)
    Organisations must build resilience to be able to deal with disruptions or non-routine events in their supply chains. While learning is implicit in definitions of supply chain resilience, there is little understanding of how exactly organisations can adapt their routines to build resilience. The aim of this study is to address this gap. An in-depth qualitative case study based on 28 interviews across five companies exploring learning to build supply chain resilience. This study uncovers six learning mechanisms and their antecedents that foster supply chain resilience. The learning mechanisms identified suggest that, through knowledge creation within an organisation and knowledge transfer across the supply chain and broader network of stakeholders, operating routines are built and/ or adapted both intentionally and unintentionally during three stages of a supply chain disruption: preparation, response and recovery. This study shows how the impact of a supply chain disruption may be reduced by intentional and unintentional learning in all three disruption phases. By being aware of the antecedents of unintentional learning organisations can more consciously adapt routines. Furthermore, findings highlight the potential value of additional attention to knowledge transfer, particularly in relation to collaborative and vicarious learning across the supply chain and broader network of stakeholders not only in preparation for, but also in response to and recovery from disruptions. This study contributes novel insights about how learning leads both directly and indirectly to the evolution of operating routines that help an organisation and its supply chains to deal with disruptions. Results detail six specific learning mechanisms for knowledge creation and knowledge transfer and their antecedents for building supply chain resilience. In doing so, this study provides new fine grained theoretical insights about how supply chain resilience can be improved through all three phases of a disruption. Propositions are developed for theory development.
  • Prediction of financial distress for multinational corporations: Panel estimations across countries.

    Apergis, Nicholas; Bhattacharya, Mita; Inekwe, John; University of Piraeus; Monash University; Macquarie University (Taylor & Francis, 2019-03-21)
    This research predicts ex-ante financial distress and analyses the link between financial distress, performance, employment, and research and development (R&D) investment in the case of multinational companies (MNCs). The conditional logit and hazard models are employed to predict financial distress, while a conditional mixed process model is employed to obtain consistent and efficient estimates. Financial distress generates contractions in performance, employment, and R&D investment. Hedging against risk mitigates the effect of financial distress on R&D. Our findings vary across countries, for example, we find MNCs in Canada, Israel and the U.S. benefit from hedging against risk. The findings also indicate that ex-ante financial distress is detrimental to employment for Canada, the U.K., the Netherlands and the U.S. The findings indicate the MNCs play different roles across countries in contributing jobs, investment in R&D during the distress period.
  • Are shocks to natural gas consumption temporary or permanent? Evidence from a panel of U.S. states

    Apergis, Nicholas; Loomis, David; Payne, James; University of Piraeus; Illinois State University; Illinois State University (Elsevier, 2010-08)
    This short communication examines whether or not U.S. natural gas consumption follows a stationary process. Unlike previous research that has focused on regional country or industrial sector-based panel studies, this study undertakes a sub-national investigation of natural gas consumption for the 50 U.S. states. Levin et al. (2002), Im et al. (2003), Maddala and Wu (1999), and Hadri (2000) panel unit root and stationarity tests reveal that natural gas consumption is integrated of order one. However, once allowance is made for endogenously determined structural breaks, the Carrion-i-Silvestre et al. (2005), Im et al. (2005), and Westerlund (2005) panel unit root and stationarity tests indicate that natural gas consumption is integrated of order zero. Discussion of the structural breaks is briefly surveyed in relation to the natural gas industry’s response to legislative actions.
  • Food price volatility and macroeconomic factor volatility: 'heat waves' or 'meteor showers'?

    Apergis, Nicholas; Rezitis, Antonios; University of Ioannina; University of Ioannina (Taylor & Francis, 2010-10-06)
    This paper investigates volatility spillover effects between relative food prices and explicit macroeconomic fundamentals, i.e. exchange rates, money balances, inflation, and the deficit to income ratio, through the methodology of GARCH models. The findings showed that significant and positive macroeconomic volatility effects influence the volatility of relative food prices. Moreover, the volatility of relative food prices exerts a positive and statistically significant impact on its own volatility. The results imply that the participation of Greece in EMU will diminish the volatility of those macroeconomic factors, implying lower volatility in food prices and thus higher benefits for both producers and consumers.
  • International technology spillovers, human capital and productivity linkages: evidence from the industrial sector

    Apergis, Nicholas; Economidou, Claire; Filippidis, Ioannis; University of Piraeus; University of Utrecht; Aristotelian University of Thessaloniki (Springer, 2009-11)
    The paper estimates an empirical model that is consistent with a variety of Research and Development (R&D)-driven models of growth where technology is transmitted via trade to other industries, both domestically and internationally, by being embodied in differentiated intermediate goods. The evidence is based on data from 21 manufacturing industries in six European Union countries for the period 1980–1997. The contribution of the paper lies in showing how by including human capital in the model and employing suitable econometric procedures the magnitude of R&D spillovers reported in the existing literature can be affected, while pointing to a major role of human capital in economic growth process.
  • The emissions, energy consumption, and growth nexus: Evidence from the commonwealth of independent states

    Apergis, Nicholas; Payne, James; University of Piraeus; Illinois State University (Elsevier, 2010-01)
    This study examines the causal relationship between carbon dioxide emissions, energy consumption, and real output within a panel vector error correction model for eleven countries of the Commonwealth of Independent States over the period 1992–2004. In the long-run, energy consumption has a positive and statistically significant impact on carbon dioxide emissions while real output follows an inverted U-shape pattern associated with the Environmental Kuznets Curve (EKC) hypothesis. The short-run dynamics indicate unidirectional causality from energy consumption and real output, respectively, to carbon dioxide emissions along with bidirectional causality between energy consumption and real output. In the long-run there appears to be bidirectional causality between energy consumption and carbon dioxide emissions.
  • Financial Deepening and Economic Growth Linkages: A Panel Data Analysis

    Apergis, Nicholas; Fillipidis, Ioannis; Economidou, Claire; University of Piraeus; University of Piraeus; University of Utrecht (Springer, 2007-04)
    The paper examines whether a long-run relationship between financial development and economic growth exists employing panel integration and cointegration techniques for a dynamic heterogeneous panel of 15 OECD and 50 non-OECD countries over the period 1975–2000. Three different measures of financial deepening are used to capture the variety of different channels through which financial development can affect growth. Our findings support the existence of a single long-run equilibrium relation between financial deepening, economic growth and a set of control variables. Further, the evidence points to a bi-directional causality between financial deepening and growth.
  • Total Factor Productivity and Monetary Policy: Evidence from Conditional Volatility

    Apergis, Nicholas; Miller, Stephen; University of Piraeus; University of Nevada Las Vegas (Wiley, 2007-08-14)
    This paper empirically assesses whether monetary policy and its volatility affect real economic activity through their effect on the aggregate supply side of the macroeconomy. Analysts typically argue that monetary policy either does not affect the real economy (the classical dichotomy) or only affects the real economy in the short run through aggregate demand (new Keynesian or new classical theories). Real business cycle theorists try to explain the business cycle with supply‐side productivity shocks. We provide some preliminary evidence about how monetary policy and its volatility affect the aggregate supply side of the macroeconomy through their effect on total factor productivity and its volatility. Total factor productivity provides an important measure of supply‐side performance. The results show that monetary policy and its volatility exert a positive and statistically significant effect on the supply side of the macroeconomy. Moreover, the findings buttress the importance of reducing short‐run swings in monetary policy variables as well as support the adoption of an optimal money supply rule. Our results also prove consistent with the effective role of monetary policy during the so‐called ‘Great Moderation’ in US gross domestic product volatility beginning in the early 1980s.
  • Renewable energy consumption and economic growth: Evidence from a panel of OECD countries

    Apergis, Nicholas; Payne, James; University of Piraeus; Illinois State University (Elsevier, 2010-01)
    This study examines the relationship between renewable energy consumption and economic growth for a panel of twenty OECD countries over the period 1985–2005 within a multivariate framework. Given the relatively short span of the time series data, a panel cointegration and error correction model is employed to infer the causal relationship. The heterogeneous panel cointegration test reveals a long-run equilibrium relationship between real GDP, renewable energy consumption, real gross fixed capital formation, and the labor force with the respective coefficients positive and statistically significant. The Granger-causality results indicate bidirectional causality between renewable energy consumption and economic growth in both the short- and long-run.
  • Testing Purchasing Power Parity: results from a new foreign exchange market

    Apergis, Nicholas; University of Ioannina (Taylor & Francis, 2010-10-06)
    This study examines whether the Purchasing Power Parity hypothesis holds in the foreign exchange market of Armenia, following the initiation of an independent foreign exchange market, after the country seceded from the Soviet Union and the rouble zone in 1993. OLS and highly efficient unit root tests provide results suggesting that PPP fails to hold both in the short-run and in the long-run, respectively. In addition, variance decompositions justify - in terms of the Balassa-Samuelson effect - why in the long-run the PPP is rejected by identifying real shocks as the main determinant of the Dram real exchange rate.
  • FINANCIAL STRUCTURE AND INDUSTRIAL STRUCTURE

    Apergis, Nicholas; Antzoulatos, Angelos; Tsoumas, Chris; University of Piraeus; University of Piraeus; University of Piraeus (Wiley, 2010-10-12)
    This paper explores the relationship between financial structure and industrial structure in a panel cointegration framework, using annual data for 29 countries and 28 industrial sectors for the period 1990–2001. The results indicate that financial structure is to a significant extent related to industrial structure in the long run, yet their relationship is partly consistent with the industrial sectors' technological orientation postulated by the theoretical literature. It is in line, however, with the so‐called ‘financial services view’ that stresses the importance of a well developed financial system for growth, irrespective of its structure. In addition, the results indicate that financial structure does not seem to play a role in a sector’s performance relative to GDP.
  • Integration properties of disaggregated solar, geothermal and biomass energy consumption in the U.S.

    Apergis, Nicholas; Tsoumas, Chris; University of Piraeus; University of Piraeus (Elsevier, 2011-09)
    This paper investigates the integration properties of disaggregated solar, geothermal and biomass energy consumption in the U.S. The analysis is performed for the 1989–2009 period and covers all sectors which use these types of energy, i.e., transportation, residence, industrial, electric power and commercial. The results suggest that there are differences in the order of integration depending on both the type of energy and the sector involved. Moreover, the inclusion of structural breaks traced from the regulatory changes for these energy types seem to affect the order of integration for each series.
  • Innovation, Technology Transfer and Labor Productivity Linkages: Evidence from a Panel of Manufacturing Industries

    Apergis, Nicholas; Economidou, Claire; Fillipidis, Ioannis; University of Piraeus; University of Utrecht; Aristotelian University of Thessaloniki (Springer, 2008-10)
    The paper explores the linkages between labour productivity, innovation and technology spillovers in a panel of manufacturing industries. The roles of R&D, human capital and international trade are considered in stimulating innovation and/or facilitating technology transfer. Using panel-based unit root tests and cointegration analysis, the results indicate the existence of a single long-run equilibrium relation between labour productivity, innovation and technology transfer. Further, R&D, trade and human capital have statistically and, especially the latter, quantitatively important effects on labour productivity both directly via innovation and indirectly as they enhance technology diffusion.
  • CO2 emissions, energy usage, and output in Central America

    Apergis, Nicholas; Payne, James; University of Piraeus; Illinois State University (Elsevier, 2009-08)
    This study extends the recent work of Ang (2007) [Ang, J.B., 2007. CO2 emissions, energy consumption, and output in France. Energy Policy 35, 4772–4778] in examining the causal relationship between carbon dioxide emissions, energy consumption, and output within a panel vector error correction model for six Central American countries over the period 1971–2004. In long-run equilibrium energy consumption has a positive and statistically significant impact on emissions while real output exhibits the inverted U-shape pattern associated with the Environmental Kuznets Curve (EKC) hypothesis. The short-run dynamics indicate unidirectional causality from energy consumption and real output, respectively, to emissions along with bidirectional causality between energy consumption and real output. In the long-run there appears to be bidirectional causality between energy consumption and emissions.
