This paper aims to investigate the sentiment connectedness among 10 European stock markets between January 2020 and July 2022, associating such connectedness with the level of the geopolitical risk index.

For this purpose, a time-varying parameter vector autoregressive connectedness framework is used.

Results show a high degree of sentiment connectedness. Overall, the sentiments of Portugal, France, the Netherlands, Spain, Germany and Italy are net transmitters of shocks while those of Poland, Sweden, Norway and Romania are net receivers. Additional evidence indicates that when geopolitical risks increase, the sentiment connectedness tends to decrease. However, the reverse holds under extremely high levels of geopolitical risks.

Overall, this study provides some significant contributions to the literature. First, to the best of the authors’ knowledge, this is among the first few studies to examine the dynamic connectedness among stock market sentiment across countries. This issue needs special consideration for European countries because of their close geographical distance and strong integration due to the European Union’s co-development strategies. Second, the association of sentiment connectedness with geopolitical risk is examined for the first time. This is even more meaningful in the context of growing geopolitical risks stemming from the Ukraine war, which could affect international financial markets.

This research aims to examine the effect of organisational culture on supply chain collaboration and firms’ competitive advantage in the garment industry in Vietnam.

Underpinned by the relational view and the organisational culture theories, the conceptual framework was proposed. This study obtained data from a survey of 192 managers in garment firms in Vietnam. A structural equation modelling was employed to examine the relationship between organisational culture, supply chain collaboration and competitive advantage.

There was a significant positive relationship between organisational culture in terms of group and development types and supply chain collaboration. Besides, the results revealed a significant positive relationship between supply chain collaboration and competitive advantage in terms of cost and differentiation. Furthermore, the cost competitive advantage was also found to have a significant positive effect on differentiation competitive advantage.

This study is perhaps one of the first empirical attempts to examine the relationship between organisational culture, supply chain collaboration and competitive advantage in the garment industry in Vietnam. Moreover, this study extends the application of the relational view and organisational culture theories in explaining these relationships in a new research context.

The study investigates determinants of willingness to pay (WTP) for laser land leveling (LLL) technology, its demand heterogeneity across individual farmers and plot characteristics and the technology's empirical impact on paddy productivity.

The study applies the Becker-DeGroote, Marschak style to elicit the WTP for LLL technology and the Cragg model to examine the determinants of the WTP to capture both the demand decision and affordability. The randomized controlled trials (RCT) are incorporated with a production function model to analyze the technology effects on paddy productivity.

The Cragg model finds that the key demographic and behavioral traits such as age, extension services and risk acceptance significantly influence the adoption decision; however, the plot area, bank and financial capacity become predominant factors in the adoption affordability. The LLL treatment effect results in a statistically significant increase in paddy yield of 6.48%, equivalent to 492,138 kg ha^-1.

The analysis underscores the factor complexity, illustrating that the LLL-promoting interventions need to address both the adoption barriers and the enablers for greater affordability. A composite of climate-smart agricultural programs should be employed to facilitate the LLL adoption. The empirical evidence highlights the positive effect on agricultural productivity, potentially offering a significant boost to output and farmer income.

The study contributes to existing literature by analyzing the heterogeneous demand for LLL technology with two distinguishable features of the paddy mono-cropping system and land fragmentation and by incorporating the RCTs alongside a production function for the effects on paddy productivity.
