• Dynamic spillover effects across petroleum spot and futures volatilities, trading volume and open interest

      Magkonis, Georgios (2017-07)
      This paper examines the existence of dynamic spillover effects across petroleum based commodities and among spot-futures volatilities, trading volume and open interest. Realized volatilities of spot-futures markets are used as inputs to estimate a VAR model following Diebold and Yilmaz (2014, 2015) and distinguish dynamic spillovers in total and net effects. Results reveal the existence of large and time-varying spillovers among the spot-futures volatilities and across petroleum-based commodities when examined pairwise. In addition, speculative pressures, as reflected by futures trading volume, and hedging pressures, as reflected by open interest, are shown to transmit large and persistent spillovers to the spot and futures volatilities of crude oil and heating oil-gasoline markets, respectively.
    • The effect of banking supervision on central bank preferences: Evidence from panel data

      Chortareas, G.; Logothetis, V.; Magkonis, Georgios; Zekente, K. (2016-03)
      We examine the effects of banking supervisory architecture on central bank preferences, quantified through a recently proposed measure of central bank conservatism. Using a dynamic panel data specification we document that central banks serving both monetary policy and banking supervision functions are less inflation conservative than those with only a price stability mandate.
    • Exploring the effects of financial and fiscal vulnerabilities on G7 economies: Evidence from SVAR analysis

      Magkonis, Georgios; Tsopanakis, Andreas (2014-07)
      We examine the possible interactions of the financial cycle and fiscal position for G7 economies. We employ the innovative aggregate financial and fiscal stress indexes which are able to depict the perplexed nature of modern economies. A SVAR model is developed to investigate the effects of both financial and fiscal stress on key macroeconomic variables. The results, using two different identification methods, reveal that financial and fiscal shocks affect negatively the key macroeconomic variables. Additionally, there is a weak feedback effect from a financial shock to fiscal sector and vice versa.
    • Factors contributing to the strength of national patent protection and enforcement after TRIPS

      Papageorgiadis, Nikolaos; Wang, Chengang; Magkonis, Georgios (2019)
      In this paper we study the determinants of the strength of patent enforcement in 43 member countries of the World Trade Organization (WTO) between 1998 and 2011, a period after the signing of the Trade-Related Aspects of Intellectual Property Rights (TRIPS) agreement. We do so by building on and expanding the seminal work of Ginarte and Park (1997) on the pre-TRIPS determinants of patent rights in the years 1960-1990. We find that in the years after TRIPS was signed, the strength of patent enforcement of a country is positively determined by two variables that signify the usage of the patent and intellectual property system, and the number of patent and trademark applications. We also find that the level of research and development expenditure, the quality of human capital, and the level of development of a country have positive effects on the strength of the enforcement of patent law in practice. Intellectual property rights enforcement is one of the key investment-related policies included in the United Nations Conference on Trade and Development (UNCTAD) Investment Policy Framework for Sustainable Development. Identifying the determinants of strong patent systems will help policymakers at the national and supranational levels to design and implement effective policies that strengthen national patent systems, thereby enhancing economic benefits such as greater levels of commercialization of intangible assets and greater levels of international trade and investment.
    • The financial and fiscal stress interconnectedness: The case of G5 economies

      Magkonis, Georgios; Tsopanakis, Andreas (2016-07)
      In this paper, we focus on the financial and fiscal stress transmission for the G5 economies. Using financial and fiscal stress indexes, we assess the spillovers within each economy, as well as the cross-sectional effects. Two supplementary methodologies, measuring the degree of interconnectedness, are employed. Our findings indicate that the interactions between these two kinds of distress are intensive, especially during and after the Global Financial Crisis outbreak. The above reiterates the necessity for coordinated macroprudential policies, as a means to confine the adverse effects of excessive financial and fiscal stress.
    • Financial Development and Economic Activity in Advanced and Developing Open Economies: Evidence from Panel Cointegration.

      Chortareas, G.; Magkonis, Georgios; Moschos, D.; Panagiotidis, T. (2015-02)
      This study considers the effects of financial development on output in a panel cointegration framework, focusing on the implications of trade and financial openness. Our analysis indicates that after controlling for cross-sectional dependence, the typical relationship between finance and output does not hold in the long run. This relationship, however, is re-established once we account for economic openness. While trade openness emerges as more important for developing countries, financial openness is more important for advanced economies. In the long run, causality runs from financial development to output in the advanced economies, while in developing economies causality is bidirectional. There is no short-run causality between financial development and output, however.
    • The financial development and growth nexus: A meta-analysis

      Magkonis, Georgios; Arestis, P.; Chortareas, G. (2014-08)
      We conduct a meta-analysis of the literature of financial development and economic growth. We cover a large number of empirical studies and estimations that have been published in journal articles. We measure the degree of heterogeneity and identify the causes of the observed differentiation. Among the most significant factors behind this heterogeneity is the choice of financial-variable proxies, the kind of data used as well as whether a study takes into account the issue of endogeneity. Our results suggest that the empirical literature on the finance–growth nexus is not free from publication bias. Also, a genuine positive effect exists between financial development and economic growth.
    • Inflation linkages within the Eurozone: core vs. periphery

      Magkonis, Georgios; Sharma, Abhijit (2019-05)
      We examine the process of inflation transmission among GIIPS countries (Greece, Ireland, Italy, Portugal and Spain) and Germany. Our findings suggest that inflation spillovers have increased since 2001. We also find that peripheral economies are (dis‐)inflation transmitters to the core. This finding is significant for policy formulation, given the very low inflation environment that currently exists in the Euro area and the macroeconomic implications that arise from this.
    • Inflation targeting and inflation convergence: International evidence

      Arestis, P.; Chortareas, G.; Magkonis, Georgios; Moschos, D. (2014-04)
      We examine whether the inflation rates of the countries that pursueinflation targeting policies have converged as opposed to the expe-rience of the OECD non-inflation targeters. Using a methodologyintroduced by Pesaran (2007a), we examine the stationarity prop-erties of the inflation differentials. This approach has the advantageof avoiding setting arbitrarily a specific country as the benchmarkeconomy. Our results indicate that the inflation rates converge irre-spective of the monetary policy framework.
    • The asymmetry of the New Keynesian Phillips Curve in the euro-area

      Chortareas, G.; Magkonis, Georgios; Panagiotidis, T. (2012)
      Using a two-stage quantile regression framework, we uncover significant asymmetries across quantiles for all coefficients in an otherwise standard New Keynesian Phillips Curve (NKPC) for the euro area. A pure NKPC specification accurately captures inflation dynamics at high inflation quantiles.
