We analyze the productivity effects of environmental (green) investment as well as of environmental expenditures and energy expenditures. For this purpose, we follow a production function approach where we account for these investment and expenditure categories as inputs. Based on a panel...

The paper reviews the application of the data envelopment analysis (DEA) method for measuring the efficiency of national innovation systems (NIS). The paper firstly visualizes the logic of DEA method and briefly summarizes the key advantages and main limitations of the DEA method. Further, this...

Efficiency scores of the National Innovation System (NIS) for 22 countries, including the BRICS, G7, are calculated with the Data Envelopment Analysis (DEA). Relevant factors that may affect the innovation system efficiency are summarized based on the NIS Approach and the New Growth Theory....

Recent studies have documented extensive heterogeneity in firm performance within countries, and innovation has been found as an important determinant. This paper addresses the issue of innovation firm performance across countries. A growing number of national firm level studies on the...

We introduce a class of production function whose inputs and outputs constitute multiples of quality and quantity. Under the efficiency unit approach, we precisely reduce innovation regarding qualitative and quantitative improvements of production to the measurement of quality-adjusted...

We stress some efficiency aspects of monopolistic competition justifying it on account of its tendency to innovate and the questionable excess capacity paradigm. Some further efficiency aspects revealed are product variety and transaction cost savings. We view the monopolistically competitive...
