The debate on deindustrialization assumes that domestic industry is a leading sector and produces positive externalities for the whole economy. This paper will partially refute this. Since the early 1990’s, most developed and emerging economies have been subjected to two paradoxes: the paradox of Solow, which calls into question the relationship between ICT investment and productivity gains, an...

Although the motivating role of feedback and progress indicators is understood in formal learning, their role in supporting incidental mobile learning is less well understood. In this paper we argue that well-designed feedback and progress indicators (FPIs) offer guidance and structure that may encourage mobile app users to move from fragmented learning episodes towards a longer term, reflectiv...

For user-friendliness purposes, many modern software systems provide progress indicators for longrunning tasks. These progress indicators continuously estimate the percentage of the task that has been completed and when the task will finish. However, none of the existing program compilation tools provide a non-trivial progress indicator, although it often takes minutes or hours to build a large...

We construct a general equilibrium model of urban unemployment with a continuum of heterogeneous urban firms producing differentiated products in a monopolistic competitive market. We show that an increase in urban institutionally fixed minimum wage reduces urban aggregate output and each urban firm will experience an output cut proportional to the change in aggregate output. However, such prop...

This paper presents a brief survey on Speech Recognition and discusses the major themes and advances made in the past few years of research, so as to provide a technological perspective and an appreciation of the fundamental progress that has been accomplished in this important area of speech communication. After years of research and development the accuracy of automatic speech recognition rem...

Heuristic search planners are so far the most successful. Almost all use as their heuristic an estimate of the distance to a goal state. We formalize a logical measure of progress, defined as a predicate P (x̄, s) true of objects x̄ at a situation s. Actions which increase P ’s extension are guaranteed to move closer to a goal situation, so that P enables us to form plans without search. One exam...

Theories suggesting either static or dynamic productivity gains derived from exports often assume the prior existence of a perfect market. In the presence of market failure, however, the competition effect and the resource reallocation effect of exports on productive efficiency may be greatly reduced; and there may actually be disincentives for innovation. This paper analyses the impact of expo...

On the optimal path of an economy with capital and non-renewable resource inputs, and constant returns output of consumption and investment, the rate of exogenous technical progress in net national product equals the rate of progress in (gross) production, divided by one minus the production elasticity of the resource flow.
