The Intertemporal Relationship Between the Currency Spot Market and the Currency Option Market

This study examines the lead/lag relationship between currency option and currency spot markets for the Deutsche mark and the Japanese yen. Using intraday currency option transactions data for the year 1989 and applying a European type currency option pricing model, pair data series of the implied and the observed exchange rates are compiled. Causality tests are then employed to test the causal relation between the observed and the implied exchange rate changes. The results indicate that the currency spot market leads the currency option market by about ninety minutes.     

Erratum to: Ethics,Diversity Management,and Financial Reporting Quality

This article proposes and empirically tests a theoretical framework incorporating Reidenbach and Robin’s (J Bus Ethics 10(4):273–284, 1991) conceptual model of corporate moral development. The framework is used to examine the relation between governance and business ethics, as proxied by diversity management (DM), and financial reporting quality, as proxied by the magnitude of earnings management (EM). The level of DM and governance quality are measured in accordance with the ratings of Jantzi Research (JR), a leading provider of social and governance research for institutional investors. This DM score is part of an index developed by JR that investment managers use to integrate DM criteria into their investment decisions. As expected, a negative relation between corporate DM development and financial reporting quality is found while controlling for other factors known in the literatures on governance and accounting choices to affect earnings quality. Despite some caveats presented in conclusion, this study contributes to the ethics, governance, and financial reporting literatures by studying the dynamics between governance and ethics in the prevention of EM.     

Causality Between Corporate Social Performance and Financial Performance: Evidence from Canadian Firms

This study assesses the causal relationship between corporate social performance (CSP) and financial performance (FP). We perform our empirical analyses on a sample of 179 publicly held Canadian firms and use the measures of CSP provided by Canadian Social Investment Database for the years 2004 and 2005. Using the “Granger causality” approach, we find no significant relationship between a composite measure of a firm’s CSP and FP, except for market returns. However, using individual measures of CSP, we find a robust significant negative impact of the environmental dimension of CSP and three measures of FP, namely return on assets, return on equity, and market returns. This latter finding is consistent, at least in the short run, with the trade-off hypothesis and, in part, with the negative synergy hypothesis which states that socially responsible firms experience lower profits and reduced shareholder wealth, which in turn limits the socially responsible investments.     

Oligopoly equilibria in exchange economies: a limit theorem

In a pure exchange economy, agents have the possibility of behaving strategically by putting only a part of their initial endowments on the market. An oligopoly equilibrium is defined to be a Nash equilibrium of the game in which agents choose simultaneously quantities to be put on the market. It is proved that under standard hypotheses, the oligopoly equilibrium leads to the competitive equilibrium when the economy is replicated an infinite number of times.

Spillover analysis across FinTech,ESG, and renewable energy indices before and during the Russia–Ukraine war: International evidence

This study is epicentral to analyze the impact of the Russia–Ukraine war on the financial markets, specifically focusing on the connectedness and spillover dynamics of FinTech, Environmental, Social, and Governance (ESG), renewable energy, gold, and Morgan Stanley Capital International (MSCI) indices in developed and emerging countries. Data are collected from Thomson Reuters, ranging from May 8, 2020, to May 11, 2022, and a time-varying parameter vector autoregression (TVP-VAR) and the dynamic conditional correlation (DCC) generalized autoregressive conditional heteroskedasticity (GARCH) t-Copula (DCC-GARCH t-Copula) are used to analyze the data. The results show that FinTech, ESG, and MSCI are net transmitters in developed countries, whereas gold and renewable energy are net receivers pre- and during war periods. ESG and MSCI are net transmitters in emerging countries, while FinTech, renewable energy, and gold become net receivers in both periods. The hedging ratio sheds light on the costs and weights of efficient pair investments that might change in the context of each region and under the combined scenario. The study has important implications for merchant bankers, policymakers, investors, hedgers, and risk managers.     

More competition to alleviate poverty? A general equilibrium model and an empirical study

In this paper, we theoretically and empirically analyze the impact of competition on poverty. We consider a general equilibrium framework with vertical preferences and compare poverty in a Monopoly setting versus a Duopoly setting considering explicitly the ownership structure. Poverty is measured by the size of the population living below an absolute poverty line. Theoretical results show that the impact of competition on poverty is contingent to the ownership structure, the poverty line and the relative dispersion of the individuals with respect to their intensity of preference for quality and sensitivity to effort: competition can improve or worsen poverty depending on the model's parameters. Empirical findings for the three existing poverty lines ($1.9, $3.2, and $5.5) are consistent to a large extent with our theoretical results.     

Scheduling Shipbuilding Using a Constraint Directed Graph Search: DAS-ERECT

To build a scheduling system for shipbuilding, we have adopted a hierarchical architecture and developed a constraint directed graph search technique for erection scheduling at the dock. First, in the hierarchical architecture, detailed schedules for the lower-level assembly plants are delegated to the individual plant's schedulers as long as the requirements from the higher-level scheduler are satisfied. However, if lower-level scheduling is impossible, the higher-level scheduler attempts to adjust the original requirements. Second, in the constraint directed graph search, the concepts of graph expansion and constraint directed pruning are amalgamated into an algorithm. The approaches are implemented in the DAS-ERECT system which is a sub-system of the DAS project undertaken for the Daewoo Shipbuilding Company.
