Canadian consumer acceptance of gene-edited versus genetically modified potatoes: A choice experiment approach

In 2016, second-generation genetically modified (GM) potatoes were approved for production and sale in Canada. In this study, we analyze how consumer acceptance of GM potatoes may be affected by various factors, including the trait introduced (i.e., the product benefits), the type of breeding technology used, and the developer of the potato using any technology. We conduct an online survey and use a stated choice experiment to collect data on consumer acceptance of GM and other potatoes in Canada. Random utility models are used to analyze the economic value consumers place on the various attributes of the potatoes. Our results show that consumers are willing to pay more for a health attribute (reduced acrylamide produced when potatoes are fried) and an environmental attribute. Respondents in general need to face discounted prices to buy potatoes created by either gene editing or GM (either transgenic or cisgenic/intragenic) technologies. However, consumers are in general more accepting of the gene editing technology than the GM technologies. Our results also show that government is the most preferred developer of the potatoes, regardless of technology. Results from this study can help guide public and private management of the introduction of new foods when the products are developed with unpopular technologies.     

The leverage effect and the basket-index put spread

Benchmark models that exogenously specify equity dynamics cannot explain the large spread in prices between put options written on individual banks and options written on the bank index during the financial crisis. However, theory requires that asset dynamics be specified exogenously and that endogenously determined equity dynamics exhibit a “leverage effect” that increases put prices by fattening the left tail of the distribution. The leverage effect is larger for puts on individual stocks than for puts on the index, thus increasing the basket-index spread. Time-series and cross-sectional variation in the leverage effect explains option prices well.     

Information asymmetry and the speed of adjustment: debasements in the mid‐sixteenth century

This article examines the impact of information asymmetry on the movement of London–Antwerp exchange rates against the backdrop of the Great Debasement of 1544–51. The case of the revaluation of gold coins in the Habsburg Netherlands in 1539, about which the sovereign and the public possessed similar information, is used as the benchmark to judge how far the speed of adjustment was affected by information asymmetry. This article is also part of the recent literature that estimates the degree of financial market integration in late medieval and early modern Europe. In the framework of the threshold autoregressive model, the speed of adjustment and the transaction costs associated with arbitrage are estimated, and the results are judged using the speed of communication as a benchmark since the flow of information played a critical role in financial arbitrage. The results reveal that the sixteenth‐century London–Antwerp exchange markets were already as integrated as that during the late nineteenth century, but information asymmetry severely disturbed the effectiveness of exchange arbitrage.

“五年规划”该规划什么,不该规划什么?

在市场经济条件下，政府制定规划的基本作用与思路为“研判未来趋势，提出发展愿景，规划政府任务”，对市场进行“负面清单管理”，对政府进行“正面清单约束”。政府应提高治理能力，努力把自己该做的事做足、做好，少搞产业政策，减少对市场干预，做真正体现小政府、大市场、由市场起决定性作用的规划。     

Regional disparity of embedded carbon footprint and its sources in China: a consumption perspective

Carbon emission reduction could be achieved through extensive cooperation between relevant groups such as businesses, governments and consumers. Generally, carbon emissions stem from consumer behaviour. To tackle the increasingly serious energy crisis and climate change in China, it is thus vital to control carbon emissions generated by the country's urban consumers. From a consumption perspective, we utilize a self-organizing feature map model to analyse the spatial differentiation of per capita embedded carbon footprint (ECF) in urban China. We found that the spatial differentiation is significant with the per capita ECF of the east coastal area at a high level and that per capita disposable income is the key factor affecting ECF. Based on these findings, potential business opportunities to develop low-carbon products are discussed.
