Machining economics problems usually contain highly nonlinear equations which may present difficulties for some nonlinear programming algorithms. An earlier article by Duffuaa et al. [1] compared the performance of several nonlinear programming algorithms, including a geometric programming algorithm, applied to five machining economics problems. Those authors concluded that the Generalized Redu...

Economic activity in different industries is linked to each other through aggregate income (horizontal linkages) and input-output relationships (vertical linkages). Could such linkages give rise to vicious circles of underdevelopment or virtuous circles of development when there are increasing returns to scale at the firm level? We show that vicious or virtuous circles based on demand linkages ...

Microbial cellulases have shown their potential application in various industries including pulp and paper, textile, laundry, biofuel production, food and feed industry, brewing, and agriculture. Due to the complexity of enzyme system and immense industrial potential, cellulases have been a potential candidate for research by both the academic and industrial research groups. Nowadays, significa...

The paper compares Feinstein’s and Clark’s consumer price and real wage indices for the British industrial revolution. The sources for their weights and component price series are evaluated. While some of Clark’s innovations are improvements, many of his changes degrade the price index. A new price index is developed using the best components of Clark’s and Feinstein’s. This index is much close...

The relationship between climate change and the macroeconomy in pre-industrial Europe has attracted considerable attention in recent years. This study follows the combined paradigms of evolutionary economics and ecological economics, in which wavelet analysis (spectrum analysis and coherence analysis) is applied as the first attempt to examine the relationship between climate change and the mac...

Using the framework of an endogenous growth model, this paper empirically analyses the relationship between trade policies and industrial growth in Pakistan during the period 1973-1995. The cointegration and error correction modelling approaches have been applied. The empirical results suggest that there exists a unique long-run relationship among the aggregate growth function of industrial val...

Academicians and practitioners are becoming increasingly interested in the economics of Information Technology (IT). In part, this interest stems from the increased role that IT now plays in the strategic thinking of most large organizations, and from the significant dollar costs expended by these organizations on IT. Naturally enough, researchers are turning to economics as a reference discipl...

In the last half-century, development economics has gone from being a fringe field of to at very centre discipline, and field’s foremost proponents have been elevated highest levels discipline. At same time, economists who study situations wherein multiple market failures lead persistent poverty ‘development-and-x’ economists, where x is any agricultural, demographic, environmental, health, lab...
