Internal And External Adjustment To New Technologies

Schumpeterian creative destruction occurs not only at the industry level, but also with each firm trying to maintain or improve its position in the technology race. Based on a rich data set on more than 4,000 German business units, this paper shows that the simultaneous occurrence of hiring and separations is more likely in firms with the most advanced technologies in use than in units more distant from the technological frontier. This positive relation between technological advance and creative destruction documented also by churning and ‘excess job reallocation equations - holds particularly in recovery years, while it is weak during a recession. The explanation provided for this finding in the paper is that firms can also improve technologies by upgrading machinery and/or retraining workers, and these ‘implementation’ costs arc likely to be lower during economic downturns.     

The business model and balanced scorecard in creative tourism: the ultimate strategy boosters

Despite the various studies on creative tourism, little managerial frameworks such as a business model and a balanced scorecard are investigated for this new phenomenon. The overall image that emerges from the literature is ambiguous and fuzzy. Also, many activities known as creative tourism experiences may provide new participative experiences but rarely include a creative process. This study covers a whole aspect in designing a feasibility test model for creative experiences based on balanced scorecard through qualitative content analysis and as the essence of that, a Business Model by content validity and clustering analysis. Analysis of data by the mentioned methods reveals that four perspectives and 13 critical success factors are essential for the feasibility of a creative tourism experience. In addition, 22 indicators in 3 main dimensions determine the success of a creative tourism business model. This study is part of a growing body of research focused on discovering hidden aspects of creative tourism.

Reconciling sustainability, systems theory and discounting

Most definitions of sustainability imply that a system is to be maintained at a certain level, held within certain limits, into the indefinite future. Sustainability denies run-away growth, but it also avoids any decline or destruction. This sustainability path is hard to reconcile with the renewal cycle that can be observed in many natural systems developing according to their intrinsic mechanisms and in social systems responding to internal and external pressures. Systems are parts of hierarchies where systems of higher levels are made up of subsystems from lower levels. Renewal in components is an important factor of adaptation and evolution. If a system is sustained for too long, it borrows from the sustainability of a supersystem and rests upon lack of sustainability in subsystems. Therefore by sustaining certain systems beyond their renewal cycle, we decrease the sustainability of larger, higher-level systems. For example, Schumpeter's theory of creative destruction posits that in a capitalist economy, the collapse and renewal of firms and industries is necessary to sustain the vitality of the larger economic system. However, if the capitalist economic system relies on endless growth, then sustaining it for too long will inevitably borrow from the sustainability of the global ecosystem. This could prove catastrophic for humans and other species. To reconcile sustainability with hierarchy theory, we must decide which hierarchical level in a system we want to sustain indefinitely, and accept that lower level subsystems must have shorter life spans. In economic analysis, inter-temporal discount rates essentially tell us how long we should care about sustaining any given system. Economists distinguish between discount rates for individuals based on personal time preference, lower discount rates for firms based on the opportunity cost of capital, and even lower discount rates for society. For issues affecting even higher-level systems, such as global climate change, many economists question the suitability of discounting future values at all. We argue that to reconcile sustainability with inter-temporal discounting, discount rates should be determined by the hierarchical level of the system being analyzed.     

Creative Destruction, Investment Volatility, and the Average Age of Capital

In this article, a new numerical procedure is used to compute the equilibrium of a vintage capital growth model with nonlinear utility, where the scrapping time is nonconstant. We show that equilibrium investment and output converge nonmonotonically to the balanced growth path due to replacement echoes. We find that the average age of capital is inversely related to output, which is consistent with recent micro evidence reinforcing the importance of the embodied question. We also find that an unanticipated permanent increase in the rate of embodied technological progress causes labor productivity to slowdown in the short run.
