abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
risk prediction plays an increasing role in financial risk management. this study aims to investigate existence of asymmetry and long memory volatility in tehran stock exchange index daily data over period of 1998-2006. 1467 daily index returns are used for volatility modeling via garch (long & short memory) processes for both normal and t-student innovations. the specification and forecasting ...
The main aim of this paper is to determine the factors which enhance or temper firms’ private incentives to use communications technologies that are characterised by network externalities and allow firms to influence their rate of technological change or total factor productivity (TFP). As regards the impact of the network effect on TFP, we find that when the externality parameter is low, a sli...
According to standard dynamic choice theories, patience is a key driving factor behind the accumulation of the proximate determinants of economic development. Using a novel representative data set on time preferences from 80,000 individuals in 76 countries, we investigate the empirical relevance of this hypothesis in the context of a development accounting framework. We find a significant reduc...
abstract the main purpose of this study was to investigate whether there was any significant difference between the speaking achievement of learners who were trained by means of consciousness raising of sociolinguistic skills and that of learners who were trained without the above mentioned task. the participants of this study consist of 60 intermediate level students participating languag...
Intra-household Resource Allocation: Do Parents Reduce or Reinforce Child Cognitive Ability Gaps? Do parents invest more or less in their high ability children? We provide new evidence on this question by comparing observed ability differences and observed investment differences between siblings in the NLSY. To overcome endogeneity issues we use sibling differences in handedness as an instrumen...
This paper examines the impact of being an innovator on firm productivity in Taiwan. Using a panel of 48794 firms observed over the 1997-2003 period, and distributed across 23 industries, we compute TFP by estimating Translog production functions with conventional K, L, E, M inputs. We evaluate the impact of being an innovator on TFP using propensity score matching. The rationale is that, over ...
This paper presents, within a framework of the Solow model, evidence that there should be two different reasons for convergence. One is due to diminishing returns to capital and the other is due to technological diffusion. This paper shows that OECD and low income countries follow a pattern of conditional convergence but middle income countries do not. This seems to imply that technological dif...
