Exploring the effect of ICT and tourism on economic growth: a study of Israel
In this paper, we explore the impact of information and communications technology (ICT) and tourism on per worker output over the period 1960β2016 by using an augmented Solow (Quart J Econ 70(1): 65β94, 1956) framework estimated through the autoregressive distributed lag procedure for cointegration (Pesaran et al. in J Appl Econ 16(3):289β326, 2001). The results show that mobile cellular subscriptions (measure of ICT pervasiveness) and visitor arrivals as a percent of workers (measure of tourism) are cointegrated and positive, however, only ICT is statistically significant in the long-run. The long-run elasticity coefficient of ICT and tourism is 0.03 and 0.05, respectively. We note a unidirectional causality from ICT to output per worker, from tourism to output per worker, from capital per worker to tourism, and from ICT to tourism. From the results, we emphasize that focusing on technology advancement and tourism expansion will provide the necessary support for economic growth in the country
Revisiting the threshold effect of remittances on total factor productivity growth in South Asia: a study of Bangladesh and India
Both Bangladesh and India are among the top recipient of remittances in absolute terms. However, in relative terms β remittances as a per cent of GDP β the two countries stand at 6.1% and 2.8%, respectively, well below the levels of the top 10 recipients. In this article, we explore the effect of remittances on the total factor productivity (TFP) growth considering Bangladesh and India, as reference countries over the periods 1980β2012 and 1977β2012, respectively. We examine the presence of a long-run association between remittances and TFP using a number of tests. The results indicate that remittances have threshold effects on TFP growth in both countries. Despite the two countries receiving substantial amount of remittances, we note that Bangladesh has a U-shaped relationship whereas India has an inverted U-shaped relationship with TFP growth. For Bangladesh, a minimum threshold of remittances (% GDP) is 5.3% and for India, a tipping point of remittances (% GDP) is at 1.8%. The causality tests confirm a bidirectional effect, which implies that remittances and TFP growth are mutually reinforcing. Interestingly, while the two economies have similar remittances impact in regards to causality, the study highlights two different tipping points of remittances
The Importance of Sociality for Understanding Knowledge Sharing Processes in Organizational Contexts
This paper explores how different models of sociality can contribute to a
better understanding of the dynamics of knowledge sharing within different
organizational settings. It is asserted that the dynamics of knowledge
sharing is organized according to a mix of four relational models
distinguished by the relation models theory (Fiske, 1991). It is described
how each of these models (communal sharing, authority ranking, equality
matching and market pricing) have their own implications for
understanding and supporting the knowledge sharing process. What model
of social relations is in use, is influenced by cultural implementation rules,
the kind of activity with its division of labor and the characteristics of
knowledge being shared and technologies being used. By knowing
according to what relational model(s) knowledge is being shared, one can
better understand and consequently better facilitate the organizational and
technical conditions for sharing knowledge (and vice versa)
Does more market competition lead to higher income and utility in the long run?
In this paper, we investigate if more competition leads to higher per capita incomes and/or to a higher level of utility in the long run. To this end, we use a Diamond overlapping-generations model but relaxing the assumption of perfect competition in the good market. We show that the weaker the competition the more unequal the distribution of income. Surprisingly, we note that in general, tougher competition does not lead either to an increase in per capita incomes or to an increase in nonfirm ownersβ utility in the long run
Tourism and economic growth in the Pacific region: evidence from five small island economies
We present a country-specific analysis on the effect of tourism on the economic growth of five small Pacific Island Countries (PICs) β Fiji, Samoa, Solomon Islands, Tonga and Vanuatu. The results show tourism development is growth-enhancing for all five countries. Foreign direct investment (FDI) is growth-enhancing for Fiji, Samoa, Solomon Islands and Vanuatu, and in the short run, a delayed negative association for Fiji and Vanuatu is found. Remittances are growth-retarding for Fiji, Samoa and Tonga, with a short-run delayed positive association for Fiji, Tonga and Samoa. Financial development is growth-retarding for Solomon Islands and Tonga, with a short-run positive association for Fiji and Samoa. While the results underscore the huge importance of tourism in generating growth and FDI in the Pacific, given the ongoing adverse effects of Coronavirus disease 2019 (COVID-19) pandemic, PICs will have to focus on alternative sectors to progress economic activities. Policy suggestions are discussed along these lines
Study on the Effect of Post Weld Heat Treatment Parameters on the Relaxation of Welding Residual Stresses in Electron Beam Welded P91 Steel Plates
AbstractResidual stresses are created by localised heating effects that occur during the welding process. Post weld heat treatment (PWHT) is the most convenient method for stress relief of welds. But PWHT cannot completely eliminate the residual stresses. So, it is essential to determine the influence of PWHT parameters like holding temperature and time on the stress relaxation for optimising the process. The selected material is modified 9Cr-1Mo (Grade 91) steel in the form of plates welded together using a high intensity electron beam. To facilitate the study, a numerical thermo-elastic-plastic model has been developed to simulate the welding of the plates. As P91 steels undergo phase transformations, the corresponding volumetric change and transformation plasticity are taken into consideration during the analysis and welding residual stresses are predicted. PWHT is implemented using Norton creep law and the residual stresses after relaxation are determined. The developed model and the predictions are validated using neutron diffraction measurements on as welded and post weld heat treated plates. A good agreement has been achieved between the measurements and predictions. The validated model has been used to study the effect of variation of heat treatment parameters like holding temperature and time on the relaxation of welding stresses
Adult Learning, Economic Growth and the Distribution of Income
Technological change causes three consequences: it guarantees economic growth, it requires employees to acquire more skills and human capital, and it increases inequality if employees are not capable adapting to new technologies. The second consequence makes it almost necessary for employees to learn during their whole working life, thereby accelerating technological change. Accordingly, the OECD (the Organization for Economic Co-operation and Development) and many governments supports the idea of lifelong learning, but it remains unclear how to finance the education of adult students who are working efficiently. In this paper, we use an overlapping generation model with human capital accumulation and inequality to derive a mechanism which reduces income inequality and provides an incentive for all adults to invest more in education. As a consequence, the growth rate of per capita income will increase and income inequality will be reduce
Nuclear spin-lattice relaxation rate in the D+iD superconducting state: implications for CoO superconductor
We calculated the nuclear spin-lattice relaxation rate for the D+iD
superconducting state with impurities. We found that small amount of unitary
impurities quickly produces the residual density of states inside the gap. As a
result, the T-linear behavior in 1/T is observed at low temperatures. Our
results show that the D+iD pairing symmetry of the superconducting state of
NaCoOH O is compatible with recent Co 1/T
experiments of several groups.Comment: 5 pages, 4 figures, minor change
