This study identified the determinants of improved rice variety adoption and measured their impact on farm productivity and the income of smallholder farmers in Indonesia.

We used a multistage sampling procedure and data from household surveys in four districts in the Banten region of Indonesia. An endogenous switching regression (ESR) model was used to estimate the impact of adoption, and the propensity score matching (PSM) non-parametric method tested the strength of the ESR findings.

The farm productivity of adoption increased by 11.45% and the income of smallholder farmers increased by 12.10% when compared to that of traditional methods.

The positive and significant effects of improved rice variety adoption indicated that research programs that develop improved rice varieties can optimize the productivity and income of smallholder farmers.

Adopting improved rice varieties increases the productivity and income of smallholder farmers, and the level of education, rice farming experience, access to extension workers, off-farm work, and mobile phone ownership have positive and significant effects on the adoption of improved rice varieties.

The role of Technology Transfer Units, examined in this study, was found to be vital to expedite the process of disseminating new varieties and their production technology.

A total of 1,000 households were surveyed in the sampled states. A probit model was used to analyse.

Age, education, land holding, tractor use and number of working family members in agriculture were found to significantly affecting adoption of the new seed varieties. Technology transfer through licensing has impacted the adoption of new seed varieties positively by highlighting Punjab possessing the highest adoption and western Uttar Pradesh was majorly adopting the old variety.

The authors believed in farmers’ memory to recall the varietal information of wheat.

The study recommended various incentives to attract the seed industry in UP to minimize the economic loss potentially suffered by them.

Quality seeds are germane to increase the productivity of crops, and it is paramount to disburse the seed varieties to the end users in an efficient way to achieve the overall objective of productivity enhancement.

In this context, a study was conducted in three states of India, namely, Punjab, Haryana and Uttar Pradesh (UP) to find out the adoption rate of newly developed varieties of wheat, HD 3086 after three years (2014–2015) of its commercialization by IARI as well as HD 2967, which was released in 2011.

The purpose of this study is to evaluate whether a diversification by grape varieties may help wine producers reduce uncertainty in quantity and quality variations due to increasingly erratic climate conditions.

This study hand-collects granular quantity and quality data from wine harvest reports for vintages 2003 to 2017 for the Valais region in Switzerland. The data allows us to obtain detailed data on harvested kilograms/liters and Oechsle/Brix degrees. It is then merged with precise meteorological data over the same sample period. The authors use this data set to capture weather conditions and their impact on harvested quantities and quality. Finally, they build portfolios including different grape varieties to evaluate whether this reduces variations in quality and quantity over vintages.

The findings highlight that the weather varies relatively strongly over the sample period and that climate hazards such as hail, frost or ensuing vine diseases effectively occur. These strongly impact the harvested quantities but less the quality of the wine. The authors further show that planting different grape varieties allows for a significant reduction in the variation of harvested quantities over time and thus acts as a good solution against climate risk.

The effect of climate change on viticulture is becoming increasingly important and felt and bears real economic and social consequences. This study transposes portfolio diversification which is central to reducing risk in the finance industry, into the wine industry and shows that the same principle holds. The authors thus propose a novel idea on how to mitigate climate risk.

The purpose of this study was to analyze, through a sequential model, the underlying mechanisms connecting transformational leadership with employee task performance. Specifically, it examined the causal chain of transformational leadership-job characteristics (task variety and task significance)-job engagement-task performance.

The hypotheses were tested on a sample of 320 employees and their supervisors from Spanish young technology and knowledge-intensive small and medium-sized enterprises (SMEs) using structural equations.

The results show that the effect of transformational leadership on task performance (assessed by supervisors) occurs sequentially via task significance and job engagement. Additionally, job engagement mediates the relationship between task variety and task performance.

Findings highlight the relevance for supervisors to employ a transformational leadership style that leads employees directly and indirectly, through task significance, to be more engaged and achieve higher task performance. They also emphasize the importance of proper job design that allows employees to be fully invested in their job performance.

Despite the importance of leadership and employee performance for the survival and growth of these firms, the study of these relationships is largely unexplored. This study proposes and tests a serial model in which supervisor transformational leadership is linked to employee task performance through two sequential mediators: job characteristics (task variety and task significance) and job engagement.

Farmers in developing countries are used to recycling and purchasing seeds of old and low-yielding varieties, leading to low seed and varietal replacement rates. Seed companies in Nepal have started to conduct traders' meetings (TMs) to promote new rice varieties. This paper aims to assess the effectiveness of this approach in promoting new rice varieties.

The authors assess the effectiveness of TMs by surveying 238 agrodealers from 7 districts of Nepal. The authors used the binary logit model to study the determinants of participation in TM and an instrumental variable approach to estimate the impact of TMs on sales of the promoted rice varieties.

Results indicate that the TM significantly influences traders' knowledge and increases the probability of selling new rice varieties promoted. However, TMs did not significantly increase the overall sales of promoted rice varieties.

The study is based on cross-section data; thus, unobserved fixed effects could not be accounted for. The study finds only one relevant and valid instrumental variable and therefore could not conduct any exogeneity test.

Seed companies in Nepal started to conduct TMs to promote new rice varieties since 2019. However, to the best of the authors’ knowledge, the usefulness of TMs and the impact of these events in changing traders' attitudes toward domestic rice seed varieties or in business performance (annual sales of the promoted varieties) have not been assessed. Therefore, the study findings will help to promote the market-driven seed system and increase the seed replacement rate.

Understanding the effect of assortment composition on attentional levels is an essential topic for academic researchers and practitioners. This work has important implications when analyzing the influence of shopping frame time and search effort on the relationship between the reaction to assortment composition and visual attention to stock-keeping units (SKUs) pricing.

Two experimental studies through gauze behavior analysis technology (using eye-tracking equipment) analyze the variable's large assortment, visual attention to SKU pricing, search effort and shopping frame time.

The results suggest that, although it increases the search effort, a large assortment decreases the visual attention to SKU pricing. Further, our results indicate a moderating effect associated with mitigating the negative effect by medium-low levels of search effort and a moderating impact of time in this relation.

Marketing professionals can carefully optimize the in-store experience by managing the assortment and variety and by influencing consumers' visual attention to SKU pricing along the journey as part of the experience. Assortment and SKU pricing strategies need to be aligned with consumer journey design.

Our findings contribute to assortment theory and management by detailing the relationship between consumers' reactions to assortment perception and visual attention to SKU pricing in time flow. We reinforce the importance of considering assortment strategies from the consumer perspective and giving reliable information about in-store behavior.

Although prior research highlights the organizational and cognitive challenges associated with achieving innovation ambidexterity, comparatively limited attention has been paid to the affective characteristics that may differentiate top management teams (TMTs) of firms. The authors build on emerging research and identify TMT entrepreneurial passion diversity as an affective characteristic with particular relevance to innovation ambidexterity.

Based on data collected from 195 small- and medium-sized enterprises in China, this study uses ordinary least squares regression models to test the hypotheses.

The results show that TMT passion intensity separation is negatively related to innovation ambidexterity, while TMT passion focus variety has an inverted U-shaped relationship with innovation ambidexterity. In addition, environmental dynamism weakens the effects of TMT passion intensity separation and strengthens the effects of passion focus variety.

This study pushes forward the research agenda on affective microfoundations of innovation ambidexterity. It also reveals the potential dark side of TMT entrepreneurial passion by explicitly delineating its effects on innovation management.

This study aims to determine white wine drinkers’ interest in Grüner Veltliner wine, a potential signature wine for the Commonwealth of Pennsylvania in the USA and identify the consumer segments likely to look for and purchase this wine varietal.

A total of 676 wine consumers from the Mid-Atlantic region in the USA were compared based on familiarity with Grüner Veltliner wine, variety-seeking (VARSEEK) scores and the likelihood of looking for and purchasing Pennsylvania Grüner Veltliner wine.

Although only a third of participants had some experience with Grüner Veltliner wine, 77% were “somewhat interested” to “very interested” in being able to sample and taste the wine, and 66%–67% were “somewhat likely” to “very likely” to look for and purchase the wine from both growing regions. Generation, wine consumption behavior and familiarity with Pennsylvania wine and Grüner Veltliner wine differed between participants based on purchase intent and VARSEEK scores (i.e. low VARSEEK/likely, high VARSEEK/unlikely). Differences in factors motivating Grüner Veltliner purchasing were also identified between low VARSEEK/likely and high VARSEEK/likely participants.

The paper presents evidence of potential demand for a signature wine from an emerging wine region. This provides direction for target marketing and related promotional strategy, along with identifying wine consumers interested in tasting and purchasing the wine.

This paper aims at understanding the causes of low adoption of hybrid rice technology. The paper also assesses the impact of adoption of hybrids and modern varieties on crop yield, vis-à-vis the old or traditional varieties.

Using unit-level data from a large-scale survey of farm households (19,877 paddy cultivators), the authors applied multi-nomial regression method to understand the factors for adoption of hybrid rice and instrumental variable method of regression to estimate its impact.

The findings demonstrate that in India, hybrid rice is often grown on relatively poor soils, resulting in greater irrigation costs and for other inputs, such as fertilizers. Further, farmers' poor access to information on the traits of hybrid rice and the associated agronomic practices, as well as poor access to financial resources, hampers efforts to scale up its adoption. More importantly, the findings reveal that the relative yield advantage of hybrids over open-pollinated modern varieties is not large enough to incentivize the rapid adoption of hybrid rice technology.

Given the higher cost of hybrids than the inbred varieties, enhancing paddy cultivators' access to financial resources can accelerate the adoption of hybrid rice in India.

The study is based on unit level data from a large-scale, nationally representative survey of farm households, comprising a sample of 19,877 paddy cultivators, spread across states in India.

The purpose of this study is to investigate the relationship between support (i.e. supervisor support (SS) and co-worker support (CS)), job characteristics (job autonomy, job complexity and skill variety) and work engagement (WE). Furthermore, the study examined whether there is a mediating effect of employee resilience (ER) on the aforementioned variables.

Data were collected from employees working in SMEs in Uganda. A sample of 324 responses was used for data analysis. Structural equation modelling and bootstrapping procedures were used to test the hypothesized relationships.

The study findings confirmed that SS, CS and job characteristics were positively related to WE. The study revealed that SS, job autonomy, job complexity and skill variety were found to foster WE through ER. Yet, CS was found not to have an indirect impact on WE through ER.

Because this study was conducted using a cross-sectional research methodology, it makes it hard to draw causal inferences.

This study’s findings contribute to the existing body of literature on WE and job characteristics and also adds to the growing body of research on ER.
