Mixture Models of Missing Data

This paper proposes a general framework for the analysis of survey data with missing observations. The approach presented here treats missing data as an unavoidable feature of any survey of the human population and aims at incorporating the unobserved part of the data into the analysis rather than trying to avoid it or make up for it. To handle coverage error and unit non-response, the true distribution is modeled as a mixture of an observable and of an unobservable component. Generally, for the unobserved component, its relative size (the no-observation rate) and its distribution are not known. It is assumed that the goal of the analysis is to assess the fit of a statistical model, and for this purpose the mixture index of fit is used. The mixture index of fit does not postulate that the statistical model of interest is able to account for the entire population rather, that it may only describe a fraction of it. This leads to another mixture representation of the true distribution, with one component from the statistical model of interest and another unrestricted one. Inference with respect to the fit of the model, with missing data taken into account, is obtained by equating these two mixtures and asking, for different no-observation rates, what is the largest fraction of the population where the statistical model may hold. A statistical model is deemed relevant for the population, if it may account for a large enough fraction of the population, assuming the true (if known) or a sufficiently small or a realistic no-observation rate.     

Explaining Differences in Economic Growth among OECD Countries

This paper re-examines the determinants of growth of GDP per capita using panel data for OECD countries for the period 1970–1999 with data averaged over five-year periods from new perspectives. First, we introduce indicators of innovation input and technological specialization simultaneously into the empirical growth equation. Second, we employ the system-GMM (Generalized-Method-of-Moments) panel estimator that controls for (a) the possible specification bias when variables are highly persistent over time and (b) the possible simultaneity bias. We find a large and statistically significant impact of business enterprise R&D (BERD) intensity on GDP per capita with an elasticity of 0.22. The share of high-technology exports is also significantly positively related to GDP per capita, but the magnitude suggests that BERD is more important than technological specialization in explaining the level of GDP per capita. Furthermore, we find that the budget deficit and government consumption (both measured as percentages of GDP) and the volatility of growth are significantly negatively related to GDP per capita.The authors would like to thank Gunther Tichy for helpful comments on an earlier draft of this article.

Attitudes Towards Paying Taxes in Austria: An Empirical Analysis

People mostly pay their taxes although there is a low probability of getting caught and being penalized. Thus, new attempts in the tax compliance literature try to go beyond standard economic theory. This paper examines citizens attitudes toward paying taxes – what is sometimes termed their tax morale, or the intrinsic motivation to pay taxes. Tax morale may be a key determinant to explain why people are honest. However, there are very few papers that explore the concept of tax morale theoretically and empirically. This study, based on the World Values Survey and the European Values Survey, therefore attempts to fill this gap in the literature, focusing on tax morale in Austria. Societal variables such as trust or pride have been identified as key determinants that shape tax morale in Austria. Furthermore, a lower perceived compliance leads to a decrease of tax morale, which indicates that social comparisons are relevant. The results also show a decrease of tax morale between 1990 and 1999, although Austrias taxpayers still have a very high tax morale compared to other European countries.     

Signalling cost with investment in compatibility

When buyers value products in terms of the expected compatibility between the current and the new vintage, firms can invest strategically in R&D to control for the switching costs. Open announcements of R&D budgets transmit information. The announcements determine the buyers' beliefs of the compatibility. As only an efficient firm finds it optimal to have a large R&D-budget, a firm can signal its unit cost. The likely outcome is a unique separating equilibrium if the marginal cost of R&D is low but the uncertainty over the rival's unit cost large. With high R&D cost, the dominating motive is to affect the rival's cost belief.     

Does Networking with Colleagues Matter in Enhancing Job Performance?

The present study empirically investigates the link between network properties and job performance using a sample of 121 middle managers from Beijing, China. The primary objective is to examine how characteristics of the person and the job moderate the effects of networks on self-rated performance. This study contributes to the network literature by investigating both the impact of network characteristics in terms of information accessibility and diversity on job performance and the interaction effects of gender, managerial rank, and functional areas of the ego with the network characteristics.     

How Network Strategies and Institutional Transitions Evolve in Asia

This article contributes to the literature on network strategies and institutional transitions in emerging economies in Asia by identifying a realistic, intermediate phase between the early and late phases of institutional transitions suggested by Peng (2003). Focusing on the intermediate phase, we advance two arguments based on network strength and network content. First, in terms of network strength, we leverage earlier insights that networks can be classified as strong ties and weak ties. Consequently, we suggest that as institutional transitions unfold, strong-tie-based networks, instead of being phased out, are being transformed into weak-ties-based networks. Second, from a network content standpoint, we argue that the various scale and scope of institutional transitions shape the content of different networks which focus on business-to-government (B2G) ties and business-to-business (B2B) relationships. Our propositions delineate how different transitions of political and legal institutions affect the evolution of B2G and B2B networks. Overall, we suggest that networks not only differ in strength but also in content, and that their evolution is driven by the impact of different dimensions of institutional transitions governing B2G and B2B relationships.

Perspectives—New Era,New Realities: Musings on a New Research Agenda… from an Old Timer

This paper provides an overview of my three primary research streams and the six principles that have guided me in topic selection in the past and which will continue to assist me in choosing research topics in the future. The paper then outlines several important themes that pertain to Asia that merit research attention in the next five to ten years.     

The Financial Impact of Organisational Downsizing Practices—The New Zealand Experience

Partly in response to the Asian economic crisis, many organisations in the Asia Pacific rim reduced staff numbers. This research examines the New Zealand experience of this change intervention from 1997 to 1999. This includes an examination of the impact on financial performance, and how the process followed may moderate such an impact. A questionnaire instrument was designed to measure this, to which responses were received from 155 New Zealand for-profit organisations employing fifty or more people.There is some evidence to suggest that those respondents who had downsized over the period of the study reported lower measures of profitability than those who did not (p < .05). Also, ensuring the procedure was perceived as just by the employees, and offering outplacement help to those who lost their jobs, went some way to improving the financial performance of downsized firms (p < .05). This may suggest that if downsizing is necessary then attention needs to be given to how the process is implemented in order to maximise the financial return.Peter Carswell teaches, consults and researches in the areas of organisational change, development, and innovation; leadership; strategic management; team building; people management and human resource training; organisational culture; management development; and entrepreneurship.

The Exogamic Nature of Sino-Foreign Joint Ventures

The paper suggests that Sino-foreign joint ventures areexogamicpartnerships. Three hypotheses were formulated: (1) partners pool differentiated sets of idiosyncratic and non-substitutable resources into their joint ventures; (2) they establish cooperation to gain access to resources provided by their counterparts; (3) the younger the partnership, the less the partners contribute with idiosyncratic resources. A questionnaire investigation was conducted into 67 Sino-foreign joint ventures. The test for H1 clearly demonstrated that each partner pools very different resources into the joint venture. H2 was also clearly supported by the data collected. However, H3 was weakly supported.     

Technology and the Size Distribution of Firms: Evidence from Dutch Manufacturing

Empirical studies have shown that the size distribution of firms can be described as a Pareto distribution. However, these studies have focused on large firms and aggregate statistics. Little attention has been placed on the role of technology in shaping firm size distributions. Using a comprehensive dataset of manufacturing firms and the Community Innovation Survey from the Netherlands, the paper investigates the relationship between firm size and technology. It shows that technological factors shape the distribution of firm size, suggesting that the Pareto law is not an invariant property and that technology can constrain the “self-organising” character of industrial economies.
