Contrasting paradigms: segmentation and competitiveness in the formation of the chinese labour market

An urban labour market is in the process of being formed in China. The objective of this paper is to analyse the stage that it has reached. A 1999 household survey is used to investigate whether the labour market has three tiers comprised of recently retrenched and re-employed urban workers, non-retrenched urban workers, and rural–urban migrants. It tests whether wage levels and structures differ across these categories of worker. Panel data are used to model the evolution of the wage structure and, specifically, the impact of retrenchment and re-employment. The results indicate that non-retrenched urban workers enjoy a wage premium, although migrants receive similar returns to education. Re-employed workers receive no return to education and appear to have lost out on the wage rises enjoyed by the non-retrenched. There is evidence to suggest that the urban labour market is segmented into these categories, which differ in their openness to market competition. The urban labour market has a long way to go before it is fully competitive.     

Advertising's Sales Effect Can Be Measured and Evaluated Very Well

Not long ago businessmen despaired because they thought that advertising's effects could not be measured at all. Now they despair because they think that measuring advertising's effects must always be a super-complicated mumbo-jumbo of econometrics and other arcane techniques that can only be understood by experts. There is no need to despair.     

Labor market integration policies and the convergence of regions: the role of skills and technology diffusion

We study the role of different labor market integration policies on economic performance and convergence of two distinct regions in an agent-based model. Production is characterized by a complementarity between the quality of the capital stock and the specific skills of workers using the capital stock. Hence, productivity changes in a region are influenced both by the investment of local firms in high quality capital goods and by the evolution of the specific skill distribution of workers employed in the region. We show that various labor market integration policies yield, via differing regional worker flows, to distinct regional distributions of specific skills. Through this mechanism, relative regional prices are affected, determining the shares that the regions can capture from overall consumption good demand. There occurs a trade-off between aggregate output and convergence of regions with closed labor markets resulting in relatively high convergence but low output, and more integrated labor markets yielding higher output but lower convergence. Furthermore, results differ substantially in several respects as distinct labor market opening policies are applied.     

THE EXPECTED SHORTFALL OF QUADRATIC PORTFOLIOS WITH HEAVY‐TAILED RISK FACTORS

Computable expressions are derived for the Expected Shortfall of portfolios whose value is a quadratic function of a number of risk factors, as arise from a Delta–Gamma–Theta approximation. The risk factors are assumed to follow an elliptical multivariate t distribution, reflecting the heavy‐tailed nature of asset returns. Both an exact expression and a uniform asymptotic expansion are presented. The former involves only a single rapidly convergent integral. The latter is essentially explicit, and numerical experiments suggest that its error is negligible compared to that incurred by the Delta–Gamma–Theta approximation.     

Time varying VARs with inequality restrictions

In many applications involving time-varying parameter VARs, it is desirable to restrict the VAR coefficients at each point in time to be non-explosive. This is an example of a problem where inequality restrictions are imposed on states in a state space model. In this paper, we describe how existing MCMC algorithms for imposing such inequality restrictions can work poorly (or not at all) and suggest alternative algorithms which exhibit better performance. Furthermore, we show that previous algorithms involve an approximation relating to a key prior integrating constant. Our algorithms are exact, not involving this approximation. In an application involving a commonly used U.S. data set, we present evidence that the algorithms proposed in this paper work well.     

Information sharing and group efficacy influences on communication and decision quality

Group efficacy has generally been found to have a positive effect on group performance. This study reveals a less favorable consequence of high group efficacy, its tendency to promote inferior group decisions under certain circumstances. Previous studies have found that members in a group generally exhibit bias towards utilizing shared information to make decisions. This study examines the effect of group efficacy on both the process (in terms of communication) and outcomes (in terms of decision quality and deviation from initial individual preference) of group decision-making. When information was not completely shared by group members prior to group discussion, members of low-efficacy groups communicated more and more readily changed their initial decision preferences. In the end, they were able to make objectively better decisions. These effects of group efficacy were even more pronounced when individual group members had conflicting information in the beginning about the issues prior to group discussion.

Tourism development in Cambodia: An analysis of opportunities and barriers

Cambodia has been perceived as one of the major destinations for development in the southeast Asia region. Information regarding the country and its attractions have been difficult to obtain. This study investigated the opportunities and barriers the Cambodian tourism industry now faces.     

Domestic market context and international entrepreneurs’ relationship portfolios

The importance of relationships to international entrepreneurs’ internationalization is well recognized, but we still know little concerning how entrepreneurs find, develop and use different types of relationships for their internationalization. In a study based on international entrepreneurship and network theories, we examine how having or not having a domestic market affects the relationship portfolios developed by born global software entrepreneurs. We find it profoundly influences the personal relationship strength they seek in new international relationships, and their activeness towards developing new relationships that are embedded in foreign markets. Further, the analytical model we develop shows how and why the presence of a domestic market influences international entrepreneurs’ portfolios of relationships.     

Going green: the evolution of micro‐business environmental practices

This paper examines the process through which micro‐businesses ‘go green’. It builds upon previous studies that have identified the different drivers of this greening process. However, rather than a static focus on specific drivers, the study articulates the evolution of environmental practices over time. The paper uses comparative case studies of six micro‐businesses to build a composite sequence analysis that plots the greening process from its roots through to large‐scale and ambitious ecological projects. The study identifies three distinct stages that businesses pass through during this greening process. This has important implications for policy‐makers and advisors as it was found that the support needed by the businesses changed as they passed through these different stages. In particular, it was found that appropriate support is currently lacking at certain key points of the businesses' greening development. The paper therefore adds to current understanding of small business ecological responsibility by showing how activities and drivers change with the level of engagement. Pointers are provided as to how support can be improved.
