Joint tests of contagion with applications

Joint tests of contagion are derived which are designed to have power where contagion operates simultaneously through coskewness, cokurtosis and covolatility. Finite sample properties of the new tests are evaluated and compared with existing tests of contagion that focus on a single channel. Applying the tests to daily euro zone equity returns from 2005 to 2014 shows that contagion operated mainly through higher order moment channels during the GFC and the European debt crisis, which were not necessarily detected by traditional tests based on correlations. The empirical results have important implications for pricing risk and constructing well diversified portfolios.     

Mandatory IFRS adoption and management forecasts: The impact of enforcement changes

We examine how concurrent enforcement changes affect the positive relationship between mandatory IFRS adoption and firms’ voluntary disclosure. We show that the increase in the issuance of management forecasts after IFRS adoption is smaller for firms from IFRS-mandating countries with concurrent enforcement changes than for those from countries without such changes. We find no difference in the increase of forecast informativeness between firms from IFRS-mandating countries without concurrent enforcement changes and firms from non-IFRS-mandating countries; however, firms domiciled in IFRS-mandating countries with concurrent enforcement changes exhibit a significantly smaller increase in forecast informativeness. Our findings suggest that better IFRS enforcement distinctly weakens (strengthens) the positive effect of IFRS adoption on voluntary (mandatory) disclosure.     

Linking owner–managers' personal sustainability behaviors and corporate practices in SMEs: The moderating roles of perceived advantages and environmental hostility

Drawing on managerial discretion and conflicting institutional logics literature, this study investigates the relation between the personal sustainability behaviors (PSB) of owner–managers and the corporate sustainability practices (CS practices) of SMEs. The research proposes a contingency model that assesses the moderating effects of perceived economic advantages and environmental hostility on this relationship. Based on linear hierarchical multiple regression analyses of a cross‐sectoral sample of French SMEs, the results suggest a positive influence of the manager's PSB on the SME's CS practices that appears to be differently moderated depending on the type of practice considered. The influence on environmental practices is fostered through the perception of economic advantages. The influence on workplace practices is only effective when the business environment is deemed benign and the influence on community practices is dampened by the perception of environmental hostility. Highlighting the trade‐off between the manager's personal values and the SME's economic constraints, these findings contribute to a better understanding of the critical antecedents of sustainability in small businesses.     

Dynamic programming for valuing American options under a variance-gamma process

Lévy processes provide a solution to overcome the shortcomings of the lognormal hypothesis. A growing literature proposes the use of pure-jump Lévy processes, such as the variance-gamma (VG) model. In this setting, explicit solutions for derivative prices are unavailable, for instance, for the valuation of American options. We propose a dynamic programming approach coupled with finite elements for valuing American-style options under an extended VG model. Our numerical experiments confirm the convergence and show the efficiency of the proposed methodology. We also conduct a numerical investigation that focuses on American options on S&P 500 futures contracts.     

Central bank credibility and the expectations channel: evidence based on a new credibility index

This article investigates the relationship between central bank credibility and the volatility of the key monetary policy instrument. First, we propose a time-varying measure of central bank credibility based on the gap between inflation expectations and the official inflation target. While this new index addresses the main limitations of the existing indicators, it also appears particularly suited to assess the monetary experiences of a large sample of inflation-targeting emerging countries. Second, by means of EGARCH estimations, we formally prove the existence of a negative effect of credibility on the volatility of the short-term interest rate. In line with the expectations channel of monetary policy, the higher the credibility of the central bank, the lower the need to move its instruments to effectively fulfill its objective.     

Technological spillovers from multinational firms

This paper aims to identify genuine technological spillovers from multinational firms (MNEs). To this end, we use data on R&D from MNEs to measure spillovers, while most of the existing literature uses output to measure the foreign presence in an industry (what we call output-based spillovers). In line with the existing literature, we distinguish between horizontal spillovers (i.e., intra-industry linkages) and vertical spillovers (i.e., backward—or downstream—and forward—or upstream—inter-industry linkages). Our results show that the three types of technological spillovers from MNEs are positive, with the horizontal spillovers the larger ones, followed by backward spillovers. The effect of forward spillovers is much smaller in magnitude. Moreover, we find that not controlling for industry size (i.e., technological spillovers from all firms in an industry) leads to underestimating both horizontal and backward spillovers from MNEs, and to overestimating forward spillovers from MNEs. Finally, we find that the distinction between technological and output-based spillovers is of great relevance. The size of backward technological spillovers is approximately 44% of the size of output-based backward spillovers, while for horizontal spillovers both types of spillovers are quite similar. Importantly, output-based forward spillovers are negative while technological forward spillovers are positive.     

Road transport productivity in the sixteenth‐century Low Countries: the case of Brabant, 1450–1650†

Though there is a consensus that transport plays a central role in economic development, for the period before the eighteenth century there is a lack of strategic information for assessing the importance of road transport productivity changes in economic development. Transport prices in particular are crucial missing pieces of the puzzle. Sources rarely reveal information that meets the standards of reliable price history. However, it is possible to create a reliable transport price series on the basis of the transport of millstones to ducal mills in Brabant. Assessing the impact of the ‘transport productivity changes’ that can be inferred from this transport price series is a hazardous exercise. Moreover, as Masschaele has observed, land transport prices closely match general agricultural price trends. Land transport was essentially an agricultural service, determined both by cost (especially horse provender) and income effects. Transport price inflation was not demand‐led. However, while transport did not impede urbanization and economic growth, conversely, in sixteenth‐century Brabant—a highly urbanized region that experienced considerable growth in the volume of land transport—no significant land transport productivity gains were achieved.     

Product-harm science communication: The halo effect and its moderators

Science communication on a product-harm situation aims to create awareness on the product's potential impacts for consumers. However, consumers tend to overestimate the information provided, due to possible halo effects. Here we designed a contextual model of halo development including individual and message characteristics detected in the literature as potential moderators. Our experimental study, based on a sample of 3,766 European respondents, evaluates these halo moderators in the context of a product-harm science communication. The results reveal a stronger halo effect on consumers' beliefs when the focal topic is considered as more important (health vs. ethics) and simultaneously when the source of information is more credible (official vs. non-official). Highly involved consumers are also subject to greater halo effects. Suggested implications mainly focus on the need to consider potential amplifying halo effects and on the importance of responding to a product-harm communication via a very accurate communication approach.     

Networks of foreign affiliates: Evidence from Japanese micro-data

The paper provides evidence of the investment patterns of Japanese multinational enterprises (MNEs) across countries and industries and analyses the main drivers of their location strategies, using detailed micro-data on Japanese parents and their affiliates including the final destination of affiliate sales. The breakdown of affiliate sales by destination market reveals that Japanese MNEs establish services affiliates primarily to maximise proximity to local customers, while foreign affiliates in manufacturing sectors tend to engage more widely with third countries. Yet, some economies emerge as strategic gateways to other destinations in their region. The empirical analysis delves into the drivers of host country attractiveness for FDI seeking new markets, production efficiency and to act as regional or global platforms. Important factors shaping Japanese FDI decisions include trade and investment policies in goods and services, deep FTAs, as well as streamlined customs procedures. Furthermore, well-calibrated rules for digital commerce and investments in digital infrastructure and innovation contribute to attracting MNEs. Overall, the paper stresses the factors behind better integration into global production networks and the policy priorities to attract various types of FDI inflows.
