We study the structure of inter-industry relationships using networks of money flows between industries in 20 national economies. We find these networks vary around a typical structure characterized by a Weibull link weight distribution, exponential industry size distribution, and a common community structure. The community structure is hierarchical, with the top level of the hierarchy comprisi...

In a variely of contexts regulatory agencies are legally obliged to use a cost-benefit rule (or some variant there of) to revise environmental standards to reflect improvements m pollution-control techniques, but have considerable discretion over the timing of such revision. How should the agency use this discretion? In a simple model of standard-setting under endogenous technical change we sho...

This paper explores the application of oblivious equilibrium to concentrated industries. We define an extended notion of oblivious equilibrium that we call partially oblivious equilibrium (POE) that allows for there to be a set of “dominant firms”, whose firm states are always monitored by every other firm in the market. We perform computational experiments that show that POE are often close to...

Throughout East Asia, the growth process and its sources are changing in a number of important respects, especially for middle and higher income economies. Growth will increasingly come from the strength of innovative activities in these economies instead of factor accumulation as in the past. Recent research suggests that such innovative activities, especially in producer services and the crea...

In recent years convergence in information industries has often taken the form of vertical agreement between different stage of the value chain and with content owners and distribution channels in a prominent position, suggesting an increasing degree of vertical integration. But when considering indicators at firm level, as the value added to revenues ratio, emerges often a reduction in vertica...

Our activities affect the environment and. the environment affects our health. As the number of humans on earth increases, our agricultural and industrial activities have a greater impact on the environment, particularly on the atmosphere. As our most precious resource, the atmosphere has been polluted, so it is imperative to take measures to control air pollution. It becomes necessary to know ...
