The Impact of Respondent and Interviewer Characteristics on the Number of “No Opinion” Answers

In this article we analyse the number of no opinion answers to attitude items. We argue that that number can be considered as a count variable that should be analysed using Poisson regression or negative binomial regression. Since we're interested in the effect of both respondent and interviewer characteristics on the number of no opinion's we use multilevel analysis that takes into account the hierarchical structure of the data. As a consequence multilevel Poisson regression and multilevel negative binomial regression are applied. Our analysis shows that answering no opinion is related to some sociodemographic respondent characteristics. In addition we find a significant interviewer effect, but we are not able to explain that effect in terms of interviewer variables.     

International Momentum Strategies

International equity markets exhibit medium-term return continuation. Between 1980 and 1995 an internationally diversified portfolio of past medium-term Winners outperforms a portfolio of medium-term Losers after correcting for risk by more than 1 percent per month. Return continuation is present in all twelve sample countries and lasts on average for about one year. Return continuation is negatively related to firm size, but is not limited to small firms. The international momentum returns are correlated with those of the United States which suggests that exposure to a common factor may drive the profitability of momentum strategies.

Asian management in the 21st century

Contrary to popular opinion, the crucial elements of the management process show strong continuity over time, but differ from one country to another, as a function of the local culture. Recent research reveals fundamental differences in the goals of business leaders from different societies. The article explores general characteristics of Asian management as opposed to management elsewhere, and what the study of Asian management and its cultural origins mean for the emerging Asian multinationals and for the state of the art in management research worldwide in the twenty-first century.

Risk,uncertainty, and asset prices

We identify the relative importance of changes in the conditional variance of fundamentals (which we call “uncertainty”) and changes in risk aversion in the determination of the term structure, equity prices, and risk premiums. Theoretically, we introduce persistent time-varying uncertainty about the fundamentals in an external habit model. The model matches the dynamics of dividend and consumption growth, including their volatility dynamics and many salient asset market phenomena. While the variation in price–dividend ratios and the equity risk premium is primarily driven by risk aversion, uncertainty plays a large role in the term structure and is the driver of countercyclical volatility of asset returns.     

Land management,erosion problems and soil and water conservation in Fincha’a watershed,western Ethiopia

The knowledge of soil erosion processes, attitude towards rational use of resources and institutional support affect the capability of farmers to implement soil and water conservation (SWC) measures. This research was conducted to determine soil erosion problems and the factors that affect the adoption of SWC measures in Fincha’a watershed, western Ethiopia. A total of 50 farmers were interviewed using a semi-structured questionnaire, and two group discussions were held with 20 farmers. Moreover, transects were walked to classify erosion features, and a quantitative erosion survey was made on 19 farm plots during the rainy season of 2004. The results showed that crop fields are affected by annual soil losses ranging from 24 to 160 Mg ha⁻¹. Farmers are well aware of these erosion problems, and related the soil loss to steep slopes and a decline in soil fertility. However, they did not invest much in SWC measures, but apply soil management practices to sustain crop yields. The wealth status of farmers, land tenure arrangements and lack of access the farmers have to information are the major factors affecting SWC adoption. High labour demand of SWC measures, lack of short-term benefits and free grazing have negatively affected SWC adoption. Soil erosion problems in Fincha’a watershed have both on-site and off-site effects that require integrated SWC planning at watershed scale.     

External technology sourcing: The effect of uncertainty on governance mode choice

External knowledge sourcing is increasingly important for corporate entrepreneurship. In this study, we examine the effect of external and relational uncertainty on the governance choice for inter-organizational technology sourcing. We develop a number of hypotheses about the impact of environmental turbulence, technological newness, technological distance and prior cooperation on the choice between different governance modes. Data about external technology sourcing transactions in the pharmaceutical industry do not provide evidence for a continuum from less to more integrated sourcing modes. However, we find that the ranking depends on the type of uncertainty, indicating that firms tackle different types of uncertainty with different governance modes.     

Innovative work behaviour and performance-related pay: rewarding the individual or the collective?

In order to change employee behaviour, companies frequently turn to forms of performance-related pay (PRP). At the same time, there is a clear imperative to encourage employee innovation. In this study we focus on the relation between PRP, organizational and job-level task resources and innovative work behaviour (IWB). In doing so, we distinguish between individual and collective PRP and build on insights from high-performance work systems and employee creativity literature. Using survey data of 927 employees from five Belgian industries, we find that individual PRP weakens the important positive relation of task-level job resources like learning opportunities on IWB. The combination of both individual and collective PRP, on the contrary, strengthens the positive relationship between organizational resources like upward communication and IWB.     

Political embeddedness and firms’ choices of earnings management strategies in China

We examine whether and how political embeddedness influences financial reporting quality in China by investigating how government ownership and political connections affect Chinese listed firms’ choices of earnings management strategies. The results show that state-owned enterprises (SOEs), and in particular, central SOEs, are more likely to substitute accrual-based earnings management strategies with costlier but less detectable real earnings management strategies than non-SOEs. The results also indicate that politically connected enterprises (PCEs) are more likely to employ less detectable real earnings management strategies than non-PCEs, so much so that PCEs’ total earnings management level is higher than that of non-PCEs.
