Transmission of CSR requirements in supply chains: investigating the multiple mediating effects of CSR activities in SMEs

In recent years, scholars have increasingly turned their attention to the separate areas of corporate social responsibility (CSR) and supply chain management (SCM). However, little scholarly attention has been paid to the transmission of CSR requirements from a small to medium-sized enterprises (SME) perspective. Drawing on institutional and innovation diffusion theories, this paper investigates to what extent the CSR requirements of customers influence the CSR activities of SMEs and their CSR requirements toward their own suppliers. Multiple mediation analysis was performed on data from a sample of 146,060 French SMEs. The findings indicate that the CSR requirements of customers have a direct negative effect on SMEs’ CSR requirements toward suppliers. However, the relationship becomes positive when we take into account the mediating role of the SMEs’ own CSR activities (i.e. economic, social and environmental activities). Furthermore, the study reveals that the indirect effect through economic CSR activities is the greatest, followed by social and then environmental CSR activities. Our main contribution is that implementing CSR activities within SMEs is a necessary step so that SMEs can be brokers in the transmission of CSR requirements in the supply chain.     

Market impact: a systematic study of the high frequency options market

This paper deals with a fundamental subject that has seldom been addressed in recent years, that of market impact in the options market. Our analysis is based on a proprietary database of metaorders—large orders that are split into smaller pieces before being sent to the market—on one of the main Asian markets. In line with our previous work on the equity market [Said, E., Bel Hadj Ayed, A., Husson, A. and Abergel, F., Market impact: A systematic study of limit orders. Mark. Microstruct. Liq., 2018, 3(3&4), 1850008.], we propose an algorithmic approach to identify metaorders, based on some implied volatility parameters, the at the money forward volatility and at the money forward skew. In both cases, we obtain results similar to the now well-understood equity market: Square-Root Law, Fair Pricing Condition and Market Impact Dynamics.     

The impact of the United States subsidies on world cotton price: evidence from ARDL bounds tests

This article investigates the impact of the United States subsidies on world cotton price in a structural framework. It starts with a simultaneous equations model of world cotton market, and then, it focuses on the reduced form. Using the Autoregressive Distributed Lag (ARDL) bounds tests of Pesaran et al. (2001), no evidence of cointegration is found between the underlying variables. This contrasts with results found in the classical framework, which highlight a strong evidence of a negative impact of subsidies on cotton price, either in the short or long run.     

Government Spending, Taxation, and Oil Revenues in Mexico

The paper analyzes the intertemporal relationship between oil duties, taxes, government spending, and GDP in Mexico during the 1981–98 period. The results from estimating a VAR model, impulse response functions, and variance decompositions on the quarterly series of taxes, government spending, oil duties, and GDP suggest that there seems to be a substitution effect between oil duties and tax revenues, and that tax revenues are not able to absorb temporary decreases in oil duties. Also, increases in tax revenue might lead to increasing government spending, but short–run increases in government spending are not likely to lead to political pressure to reduce the expected budget deficit via increased taxation and/or oil revenues. Lastly, GDP is not stimulated in the short–run by temporary increases in government spending and, thus, stabilization measures adopted in recent years to reduce the size of the government are not likely to significantly undermine GDP growth.     

Inflation,real economic growth and unemployment expectations: an empirical analysis based on the ECB survey of professional forecasters

Expectations are at the centre of modern macroeconomic theory and policymakers. In this article, we examine the predictive ability and the consistency properties of macroeconomic expectations using data of the European Central Bank (ECB) Survey of Professional Forecasters (SPF). In particular, we provide evidence on the properties of forecasts for three key macroeconomic variables: the inflation rate, the growth rate of real gross domestic product and the unemployment rate.     

Nonlinear models with panel data

Panel data play an important role in empirical economics. With panel data one can answer questions about microeconomic dynamic behavior that could not be answered with cross sectional data. Panel data techniques are also useful for analyzing cross sectional data with grouping. This paper discusses some issues related to specification and estimation of nonlinear models using panel data.JEL Classification: C230The research behind this paper was supported by the National Science Foundation, the Gregory C. Chow Econometric Research Program at Princeton University, and Danish National Research Foundation (through CAM at the University of Copenhagen).

Increasing the usability and accessibility of geodynamic modelling tools to the geoscience community: UnderworldGUI

Geoscientists are faced with a number of complexities that represent obstacles to the development of realistic simulation of deep earth processes. Realistic 4D thermo-mechanical simulation using software packages like Underworld and Gale, when combined appropriately with geoscientific expertise, can lead to novel insights into the deformation of geological structures at a wide range of time and spatial scales. The challenge for end-user geoscientists lies in applying their knowledge within the framework of the software’s input specification, including initial, internal, and boundary conditions and output visualization parameters. We have built a Graphical User Interface (GUI) to remove many of the difficulties related to editing the Extensible Markup Language (XML) encoded input files of Underworld/Gale geomodels and therefore, to greatly broaden the user base of these software packages. By helping Underworld/Gale to meet a large audience, we provide a tool to the geoscience community that helps to move from untested conceptual models to physically valid, properly scaled modelling. Furthermore, the UnderworldGUI offers a mechanism for storing and retrieving experimental models in a centralised database, thus providing the geoscience community with a means to share the outcomes of its experimental research. Further details of the UnderworldGUI are available at the web site http://www.wiki.vislab.usyd.edu.au/moinwiki/UnderworldGUI.     

The fundamental theorem of asset pricing under transaction costs

This paper proves the fundamental theorem of asset pricing with transaction costs, when bid and ask prices follow locally bounded càdlàg (right-continuous, left-limited) processes. The robust no free lunch with vanishing risk condition (RNFLVR) for simple strategies is equivalent to the existence of a strictly consistent price system (SCPS). This result relies on a new notion of admissibility, which reflects future liquidation opportunities. The RNFLVR condition implies that admissible strategies are predictable processes of finite variation. The Appendix develops an extension of the familiar Stieltjes integral for càdlàg integrands and finite-variation integrators, which is central to modelling transaction costs with discontinuous prices.
