The impact of job embeddedness on innovation‐related behaviors

It has often been argued that low turnover leads to less innovation in organizations, not only because fewer job vacancies are available for outsiders with new ideas, but also because longer‐tenured employees might be more resistant to change. In this study, we propose that job embeddedness may actually strengthen employees' motivation to generate, spread, and implement innovative ideas in organizations. In a longitudinal study with a diverse sample, we found that job embeddedness was positively and significantly related to innovation‐related behaviors, even after controlling for demographic variables, the job attitudes, and the job perceptions that are frequently associated with job embeddedness. In addition, we found some support for the proposed moderating effects of career stage; that is, the relationship between job embeddedness and implementing innovative ideas was stronger for individuals in the mid‐ and late stages of their careers than for those in the early stage of their careers. This article concludes with directions for developing future theory. © 2010 Wiley Periodicals, Inc.     

Elasticity estimates of farmed salmon demand in Spain and Italy

In this paper, estimates of the elasticities that characterize the structure of demand for farmed salmon in Spain and Italy are reported. The demand models are specified using a Box-Cox transformation of the variables and a Hausman test is used to determine price endogeneity in the demand equations. The results show short-run unitary own-price elasticity of demand for farmed salmon in both markets, but long run estimates show significant elastic price response. Short run substitution of salmon for other fish species is not observed and, for both Spain and Italy, farmed salmon is characterized as a luxury good. Interestingly, we show that our a priori expectations about own-price elasticities being lower in smaller market areas is confirmed. Finally, the results obtained are compared to other recent results reported in the salmon demand literature.

Measuring a boom and bust: The Sydney housing market 2001–2006

The Sydney housing market peaked in 2003. The period 2001–2006 is, therefore, of particular interest since it captures a boom and bust in the housing market. We compute hedonic, repeat-sales and median price indexes for five regions in Sydney over this period. While the three approaches are in broad agreement regarding the timing of the turning point in the housing market, some important differences also emerge. In particular, we find evidence of sample selection bias in our hedonic and repeat-sales data sets (with the former focusing more on better quality dwellings and the latter more on lower quality dwellings). These sample selection biases could in turn cause bias (in opposite directions) in our hedonic and repeat-sales indexes. Median indexes may likewise be biased as a result of an apparent decline in the average quality of dwellings sold in the latter part of the sample. We also find evidence of convergence in prices across regions during the boom and divergence in the subsequent bust.     

Organizational differences in managerial compensation and benefits in Chinese firms

More than two decades of economic reforms have brought profound changes in human resource management practices in both the state and non-state sectors in China. This study focuses on the impact of organizational factors on compensation and benefits for Chinese managers in state-owned enterprises (SOEs), publicly listed firms (PLFs), and foreign-invested enterprises (FIEs). The empirical investigation of 465 firms located in three major Chinese cities, Shanghai, Nanjing and Guangzhou, provides evidence that organizational factors, such as ownership, firm size, firm age, location and industrial sector, have significant impacts on the variances in Chinese managers' compensation levels, compensation structures and benefits. The trends in the development of compensation and benefits for Chinese managers are also discussed as the Chinese economy moves closer to a more globalized, highly dynamic economy after China's accession to the World Trade Organization in 2001.     

Significant drivers of growth in Africa

We employ bootstrap techniques in a production frontier framework to provide statistical inference for each component in the decomposition of labor productivity growth, which has essentially been ignored in this literature. We show that only two of the four components (efficiency changes and human capital accumulation) have significantly contributed to growth in Africa. Although physical capital accumulation is the largest force, it is not statistically significant on average. Thus, ignoring statistical significance would falsely identify physical capital accumulation as a major driver of growth in Africa when it is not.     

Coping with Technological Change: The Role of Ability in Making Inequality so Persistent

This study provides an explanation to the evolution of wage inequality over the last 30 years and supports this explanation with evidence. A faster rate of technological progress introduces new unknown elements at the workplace. The need to cope with the unknown accentuates the role of ability and thus increases wage inequality within and between education groups. Inasmuch as education is an irreversible investment project the rise in within group inequality BOOSTS UP the rise of between group inequality. Guided by this theory we turn to the PSID for evidence. Using parents' education to approximate child's ability we show the following set of results: (a) Controlling for education of the child, parents' education contributed much more in the 1980s to his wage growth than in the 1970s. (b) The correlation between the parents' and the child's education increases from the 1970s to the 1980s. (c) The return to college education for an individual with no ability rents did not change—it remains steady at the 23 percent. (d) Facts (a)–(c) CANNOT be attributed to the impact of parent's income. It is parents' education and not parents' income that is more relevant for son's economic outcomes in the 1980s.     

Planting flexibility: Implications for agricultural sustainability

There is a general belief that federal commodity programs restrict adoption of more sustainable production systems. In the 1990 farm legislation, Congress introduced limited planting flexibility to address these concerns and to reduce federal farm program costs. This program estimates the impact of planting flexibility on selected agricultural sustainability indicators and its policy implications. Results show that planting flexibility is a necessary but not sufficient condition for implementing more sustainable production systems. Other factors such as the availability of economically viable alternatives, macroeconomic conditions, and local resource and environmental concerns need to be considered. Policy reforms can help in achieving economic and environmental gains only in locations with economically viable alternatives. In other cases, increased research and development of new systems are needed to achieve desired results.
