Factors affecting investors’ intention to purchase gold and silver bullion: evidence from Malaysia

Gold and silver prices have surged since the 1980s, and they have been used as a store of value for fear of a financial meltdown. However, gold and silver in the form of bullion are still not so popular compared with other gold and silver products (jewellery) and other financial instruments in Malaysia. Limited study has actually verified the factors that affect the investors’ intention to purchase bullion. Thus, this study explores factors affecting investors’ behaviour and their intention to purchase bullion based on the Theory of Planned Behaviour. This study also examines the moderating effect of scepticism between investors’ behaviour and their intention to purchase bullion. A total of 208 sets of data collected in a self-administered online structured survey was analysed using PLS-SEM. This study finds that investors’ behavioural belief and control belief significantly and positively affect their respective attitude towards behaviour and perceived behavioural control and, thus, intention to purchase bullion. Results are found insignificant for normative belief, normative attitude and intention to purchase bullion and the moderating effect of scepticism in affecting investors’ intention to purchase bullion. The findings of this study hope to provide insight and deeper understanding to bullion traders and financial advisors in improving their marketing strategies in growing interest in the bullion market.

互联网金融影响了商业银行流动性创造吗?

选取2010-2019年中国98家商业银行年度数据就互联网金融对银行流动性创造的影响及其作用机制进行实证分析.研究发现:互联网金融通过分流银行存款及理财资金对银行盈利形成冲击,由此引发的"鲶鱼效应"会倒逼银行加大存贷期限错配来缓解盈利下降压力,从而促进银行流动性创造.相对于国有银行与城农商行,互联网金融对股份制银行流动性创造的促进力度更大.金融脱媒仅在P2P网络借贷对银行流动性创造的影响中承担着中介作用,但"第三方支付-金融脱媒-银行流动性创造"的传导渠道无效.银行业景气度提高会加剧互联网金融对流动性创造的促进作用,银行流动性创造存在顺周期倾向.     

Impact of Outward Foreign Direct Investment on Chinese Manufacturing Firms' Financialization and Servitization

This study examines the impact of outward foreign direct investment (OFDI) on Chinese manufacturing firms' financialization and servitization. Using a difference-in-differences approach with propensity score matching, we found that OFDI encouraged firms' financial and service activities. The effects of OFDI on financialization were stronger for firms specializing in short-term financial assets, operating in labor and technology-intensive sectors, investing overseas to pursue production, resources and markets there, and investing in non-OECD and Belt and Road Initiative (BRI) countries. Meanwhile, firms investing overseas were more likely to provide services at the sale or postsale stages. Outward foreign direct investment has also boosted the service activities of firms operating in the technology-intensive sector by investing overseas to seek resources and markets, as well as investing in non-OECD and BRI countries. Finally, OFDI partially influenced the extent of financialization and servitization of firms by affecting their profit-making ability.
