GOVERNANCE OF GLOBAL SUPPLY CHAINS VULNERABILITY BY BUSINESS-BASED INTERORGANIZATIONAL INFORMATION PLATFORM

The paper introduces the business-based interorganizational information platform（IOP） and analyzes the feasibility and mechanism of business-based IOP governing global supply chains vulnerability,and then aims to develop a risk evaluation software under reliable algorithm to appraise the capability of an interorganizational information platform resisting to global supply chains risks that supports platform users and providers to make decisions.The paper respectively starts with a basic conceptual model of global supply chains vulnerability and a conceptual model of global supply chains vulnerability in business-based IOP,and then gives the simulation model of governance of global supply chain vulnerability in business-based IOP;then has a discussion with the beneficial model of governing global supply chains vulnerability by using business-based IOP or not.The results of research：（1） If given the ratio of expense per income on global supply chains using business-based IOP, we can estimate the costs to take precautions against risks that decides to the maximum value of the average income of per transaction on global supply chains using business-based IOP.（2） If given total income of transaction on global supply chains using business-based IOP,we can estimate the maximum value of the ratio of expense per income on global supply chains using business-based IOP, which would help to make pricing policy for IOP service provider.

A blockchain-based multisignature approach for supply chain governance:A use case from the Australian beef industry

This paper designed and implemented a blockchain-based multisignature approach to digitally transform supply chain governance in multi-tier food supply chains,particularly in a geographically dispersed beef supply chain.An exploratory case study was utilised to demonstrate the design,implementation,and evaluation of a blockchainbased multisignature approach that was deployed on the Smart Trade Networks(STN)Proof of Authority(PoA)blockchain system for data collection and validation in a beef supply chain context.The multisignature approach was implemented with a use case to track a shipment of 92 cattle and meat products through key events from farm to food service.The use-case deployment records approximately 6000 data points registered on the STN PoA blockchain system.The real-case deployment illustrates the capability of the blockchain-based multisignature approach to digitally improve beef supply chain governance by enabling whole-of-chain transparency and trustworthy information sharing and supports supply chain professionals to have a better understanding of how to unlock blockchain potential for supply chain transformation.

Cultural similarities and housing market linkage： evidence from OECD countries

The subprime crisis provoked a growing study on international housing market linkage. Nevertheless, the extant literature fails to explore housing price co-movements in terms of culture and a country＇s responses （e.g. housing market conditions and government participation）. Employing the databases on cultural similarities, housing market conditions and government participation in 18 OECD countries over 1970-2016, this article suggests that culture similarities affect house price co-movements via information dissemination efficiency and investment conduct consistency. In addition, housing supply elasticity and government participation are able to mitigate house price contagion. Hence, to withstand external shocks, countries should pay attention to the role of cultural similarities in housing price interdependence. Moreover, it is necessary to ensure that housing supply is resilient and improve government participation.

A Case Against Zero Capital-Income Taxation

This paper develops a dynamic general equilibrium model to investigate the optimal level of capital income taxation in light of stochastic endogenous economic growth. Although endogenous human capital is incorporated into our model, we restrict our investigation to the issue of optimal physical capital income tax; and the labor supply is also endogenously determined. This paper proves that the optimal capital income tax should be zero provided exogenous government expenditure on production; however, capital income should be taxed if we consider endogenous government consumption.
