Global competition has forced companies, including small and medium enterprises (SMEs), to improve their competitive advantage. Supply chain management practices are the ways to improve the competitive advantage, particularly in the global competition context. However, there is still doubt SMEs can compete globally, considering they face limited resources, skilled workforce, and business networks. Therefore, this study aims to examine the influence of supply chain management practices, covering cross-functional integration, partnership, responsiveness, and resilience. Moreover, this study has examined which practices dominate in improving competitive advantage. The quantitative study involved 445 SMEs located in East Java, Indonesia. The respondents are supervisors or higher levels and work in departments related to supply chain management, as they can provide the relevant information and possess complete knowledge of management practices. The data were collected via a questionnaire designed with a five-point Likert scale. The responses were analyzed using SmartPLS software 4.0. The results show that cross-function integration improves supply chain partnership, responsiveness, and resilience (β = 0.705, 0.382, 0.324; t-value = 25.177, 6.697, 5.783). Supply chain partnerships affect supply chain responsiveness, resilience, and competitive advantage (β = 0.327, 0.257, 0.249; t-value = 5.933, 4.536, 5.651). Moreover, supply chain responsiveness improves supply chain resilience and competitive advantage (β = 0.285, 0.106; t-value = 5.690, 2.099). Supply chain resilience improves competitive advantage (β = 0.435 and t-value = 8.987). SMEs can enhance their competitive advantage by integrating their internal cross-functional integration and adopting supply chain partnership, responsiveness, and resilience.

The government bond (GB) has become the most attractive investment portfolio option, even though many macroeconomic factors affect the bond yield. This paper aims to investigate the determining factor of local currency government bond yield by considering the inflation rate, credit default swap, stock market index, exchange rate, and volatility index. This study used 240 data panel from the Bloomberg stock market in the form of data panel covering Southeast developing countries, namely Indonesia, Thailand, Malaysia, and the Philippines, for five years or sixty months from January 2015 to December 2019. Data analysis used recursive models and multivariate regression techniques using EViews software. The random effect model results revealed that change in the foreign exchange rate and volatility indexes affected, partially and simultaneously, the changes in the stock market index. The result also showed that changes in the stock market index, inflation rate, and credit default swap affected, partially and simultaneously, government bond yield changes. These results suggest that the government bond yield could be managed by controlling volatility index, foreign exchange rate, stock market index, inflation rates, and credit default swaps. This finding could provide an insight into the policymaker and fiscal authority on managing the risk of government bonds under control during high volatility or even making it reasonably lower. This result could contribute to the current research in the field of financial management.
