The objective of this note is to analyze some implications of the model of commodity money described in Banerjee and Maskin (1996) which may seem paradoxical. In order to do this, we incorporate a general production cost structure into the model. We focus on two different results. First, the existence of technologies that make counterfeiting a commodity more difficult may exclude it from being ...

Despite the impressive photovoltaic performances with power conversion efficiency beyond 22%, perovskite solar cells are poorly stable under operation, failing by far the market requirements. Various technological approaches have been proposed to overcome the instability problem, which, while delivering appreciable incremental improvements, are still far from a market-proof solution. Here we sh...

Use of efficiency measures as a proxy for performance to test the market structureconduct-performance (SCP) hypothesis is explored. Utilizing Battese and Coelli specification, we estimate stochastic frontier production function and SCP equations with output and efficiency measures as endogenous variables. An empirical application to U.S. trucking carries over the period 1994-2003 with emphasis ...

Wearable computing promises to gain efficiency improvements in industrial applications due to augmentation of the device as well as improved interaction between the user and the device. In this paper, we present the results of a study with focus on utilization of wearable computing in industrial service applications. Our study consisted of a preliminary market scan with regard to wearable compu...

As we enter the post-pandemic period, United Nations' first priority related to sustainable development is facilitate a green transition, whereby “investments must accelerate decarbonization of all aspects our economy.” A 2009 study conducted by The Rocky Mountain Institute stated that “The role energy efficiency has historically played in US generally under appreciated. If productivity had rem...

the paper examines industrial concentration in iranian food products and beverages industries using firm level data aggregated to the 4-digit isic industry level between 2002 and 2004. based on different concentration indices the average level of concentration has increased slightly for the period of study. the empirical results show that increase in the level of concentration is more likely in...

This paper analyses the impact of technological change and productive efficiency on the dynamics of industrial competition. Our theoretical model takes into account the innovation possibilities and the organisational structure of the firm. It considers three decision stages in which firms first have to solve for output and profits (and the market price), given the state of production techniques...

This work presents some preliminary results of a project aimed at the application of industrial Model Predictive Control (MPC) to thermal Power Plants. The rationale which motivates this research is the need to improve the efficiency of power plants to cope with the high levels of competitions induced by the liberalization of the energy market. A detailed plant simulator is coupled to an indust...
