Feenstra and Ma (2008) develop a monopolistic competition model where firms choose their optimal product scope by balancing the profits from a new variety against the costs of “cannibalizing” sales of existing varieties. While more productive firms always have a higher market share, there is...

In the paper factors of economic growth according to Solow have been discussed. The role of technology as the determinant of this growth has been underlined. An attention has been focused on disastrous situation of scientific research in Poland due to very low financing from budget and industry...

In markets where spatial competition is important, many models predict that average prices are lower in denser markets (i.e., those with more producers per unit area). Homogeneous-producer models attribute this effect solely to lower optimal markups. However, when producers instead differ in...

The analysis of innovation and the evolution of industries evolution has witnessed major progress in several areas. Contributions at the empirical, appreciative, econometric and modelling levels have greater advanced our understanding of innovation, industrial dynamics and the different...

In this paper, we specify a theoretical dynamic oligopoly model with regard to asymmetric firms. We then estimate a structural dynamic model of demand and pricing relations for the semiconductor industry. Using quarterly firm-level output and cost data as well as industry prices from 1974 to...

A substantial number of studies have extended the work on universal properties in physical systems to complex networks in social, biological, and technological systems. In this paper, we present a complex networks perspective on interfirm organizational networks by mapping, analyzing and...

This paper analyses the determinants of intra-industry trade (CININ), vertical (CININV) and horizontal (CININH), inside the commercial relationship between Mexico and United States, in the period 1985-2006, for 22 industries, employing Adjusted Grubel-Lloyd and Kojima indices. Estimations...

It is well known that economic growth and services have a positive association. In particular, the more developed an economy is, the higher the share of the services sector. While most research has focused on service output, this study also examines services as input. Recently, the need for...

The Council for Scientific and Industrial Research (CSIR) Ghana, together with the Natural Resources Institute of the United Kingdom and with input from the Ghana Institute of Management and Public Administration convened a one-day Policy Dialogue Forum on “Broadening Monitoring and Evaluation...

It is well known that new businesses are typically much smaller than their established industry competitors, and that this size gap closes slowly. We show that even in commodity-like product markets, these patterns do not reflect productivity gaps, but rather differences in demand-side...
