Sources of Economic Growth in Models with Non-Renewable Resources

This paper re-examines the possibility of endogenous long-term economic growth in neoclassical models with non-renewable resources. Instead of using a Cobb-Douglas production function as in most existing studies, we consider a general class of production functions in which physical capital is functionally separable from labour and natural resources. It is shown that if the elasticity of substitution between labour and resources is identical to one, then long-term economic growth is endogenous. But if this elasticity is bounded above or below by one, as suggested by empirical evidence, then long-term economic growth is determined a priori by an exogenous technological factor

Sources of Economic Growth in Models with Non-Renewable Resources

This paper re-examines the possibility of endogenous long-term economic growth in neoclassical models with non-renewable resources. Instead of using a Cobb-Douglas production function as in most existing studies, we consider a general form in which physical capital is functionally separable from labour and natural resources. It is shown that if the elasticity of substitution between labour and resources is identical to one, then long-term economic growth is endogenous. But if this elasticity is not equal to one, as suggested by empirical studies, then long-term economic growth is entirely driven by an exogenous technological factor

Sources of Economic Growth in Models with Non-Renewable Resources

This paper re-examines the conditions under which endogenous economic growth can emerge in neoclassical models with non-renewable resources. Unlike most of the existing studies which focus exclusively on Cobb-Douglas production function, our analysis is based on a general specification. We formally prove that endogenous growth can emerge only under the "knife-edge" condition of a unitary elasticity of substitution between labour input and resource input. If this elasticity is not equal to one (as suggested by empirical evidence), then long-term economic growth is entirely driven by an exogenous technological factor. We also explore the implications of this on resource taxation

(Promoting Knowledge Sharing Behavior of Educational Quality Assurance Officers in Srinakharinwirot University) Abstract   The purpose of this mixed method research were 1) to study knowledge sharing behavior; 2) to study  factors  related  to knowledge sharing behavior; and 3) to find guiding principles to promote knowledge sharing behavior of educational quality assurance officers  in Srinakharinwirot University (SWU), Bangkok.  Data were collected by questionnaires, in-depth interviews, and focus group discussions.  The sample consisted of 262 educational quality assurance officers from 33 units of  SWU and the results were as follows: 1) Explicit and Tactic knowledge sharing behavior were at a high level.  2) All of social and psychological factors  were positively correlated to explicit  and tactic knowledge sharing behavior. Findings showed that explicit knowledge sharing behavior had the highest correlation with ability of work , followed by information  technology  and achievement motivation respectively. Moreover, explicit knowledge sharing behavior had the highest correlation with ability of work, followed by achievement motivation and organization atmosphere respectively.  3) The results of this research could be used to develop and promote knowledge sharing behavior of educational quality assurance officers in SWU.   Keywords: knowledge sharing behavior, educational quality assurance officers

Three Essays on Natural Resources, Climate Change and Economic Growth

This thesis contains three main chapters that explore various issues related to natural resources, climate change and long-term economic growth. In Chapter 2, we examine the conditions under which endogenous long-term economic growth will emerge in an overlapping-generation model with productive non-renewable resources. We formally prove that the elasticity of substitution between labour and natural resource input plays a crucial role in generating endogenous long-term economic growth. In Chapter 3, we examine how the substitutability between renewable and non-renewable resources will affect long-term economic growth. To achieve this, we develop two discrete-time endogenous growth models with both renewable and non-renewable natural resources. These two types of resources enter into the production function through a constant-elasticity-of-substitution (CES) aggregator. The ease or difficulty in substituting between these two inputs is then captured by a single parameter, namely the elasticity of substitution. We then analyse how changes in this elasticity will affect long-term economic growth. Finally, in Chapter 4, we develop a multi-sector neoclassical growth model to analyse the effects of climate change on economic growth and the allocation of productive inputs and outputs across sectors. A novel feature of this model is that it takes into account the differential impact of global warming on agricultural and non-agricultural productivity growth. In particular, the effect of climate change on long-run growth is well-characterised. However, the impacts on long-run allocation of labour across sectors as well as value-added shares are ambiguous due to ambiguity effect of the climate impact on capital return.</div

The Structural Transformation of Thailand: The Role of Policy Distortion

Thailand and the Republic of Korea were developing at a similar pace during the 1960s. However, the Republic of Korea’s economic development rapidly expanded from the 1970s onward, leaving Thailand lagging far behind. This paper investigates the labor productivity slowdown in Thailand using a nine-sector, structural transformation model setting with policy distortions. Our findings suggest that the economic underdevelopment of Thailand, when compared with the Republic of Korea, lies in a tendency toward relative labor productivity slowdowns resulting from both direct and indirect policy distortions in the agriculture sector. The agriculture sector has consistently been overlooked by the government in favor of the infant industrial sector for many decades. Moreover, as the agriculture sector accounts for a relatively considerable share of employment, the magnitude of the negative impact from policy distortions is amplified, inducing a delay in Thailand’s structural transformation

Effect of sweet basil ocimum basilicum l. leaves powder on qualities of pork emulsion sausage (Moo Yor)

RMUTP Research Journal, Vol. 12, No. 1, (Jan-Jun. 2018), p.77-91Effect of sweet basil (Ocimum basilicum L) leaves powder (SBP) (0.25-1.0%) on qualities and lipid oxidation of pork emulsion sausages (Moo Yor) during 21 days of refrigerated storage was investigated. Control sample had lower fiber content than samples added with SBP (p<0.05) at day 0 of storage. Samples treated with SBP (0.25-1.0%) had lowr L* value but higher b* value, compared to the control samples (p<0.05). With the addition of SBP, peroxide value (PV) and thiobarbituric acid-reactive substances (TBARS) value in the sausages were retarded effectively, compared to the control sample (p<0.05), especially when the SBP at high contents were used. Samples treated with SBP had higher hardness, compared with control sample during storage (p<0.05). SBP had no detrimental effect on the sensory attributes of sausages. Therefore, SBP can be utilized in sausages to enhance shelf life quality.Rajamangala University of Technology Phra Nakho
