Firstly, by surveying recent research, this paper confirms that both the production and use of ICT have been the factors behind the improved economic performance of the United States in the 1990s. However, the evidence for the New Economy is much weaker outside the United States. Secondly, the paper applies growth accounting to estimate the impacts in Finland. It is shown that the contribution ...

the study examined relationship between the gross domestic product (gdp) of nigeria with the inputs of labour, capital and the output of fisheries. this is to ascertain that the fisheries contribution to the economy is more than is recorded in the sense that taking its indirect and direct economic impact into account, its overall contribution to the gdp of nigeria may be higher than that measur...

We study how external versus internal innovations promote economic growth through a tractable endogenous growth framework with multiple innovation sizes, multi-product firms, and entry/exit. Firms invest in external R&D to acquire new product lines and in internal R&D to improve their existing product lines. A baseline model derives the theoretical implications of weaker scaling for external R&...

Product lines engineering was born in the 80’s as an economic theory to increase economy of scale. Nowadays, the software product lines approach is promising, encouraging researchers and industrials to collaborate in order to increase software quality and to reduce software development costs. Convincing results have been achieved in specific domains, focusing on constructive (not opportunistic)...

The welfare cost of imperfect competition in the product and labor markets in the United States is quantified in a dynamic general equilibrium model. We find that the welfare cost of imperfect competition in the product market is 3.62 percent while it is 0.58 percent in the labor market, taking the transition path from the distorted to the optimal steady state into account. If we also take into...

I present a model where firms and workers set wages above the market-clearing level. Unemployment is thus generated by their exercise of market power. Because both the labor and product markets are imperfectly competitive, market power in the labor market interacts with market power in the product market. This interaction sheds new light on the effects of policy interventions on unemployment an...

With the continuous development of economy and science, medical instrument entered the digital and informational age. Conflicts between the urgent requirement and severe lack for ergonomics in the industrial design of medical instrument products became increasingly fierce. In the present paper, we attempted to use the research achievements in the area such as product form design theory, ergonom...

In a dynamic general equilibrium model we explictly consider the relationship between the product attributes ’durability’ and ’recyclability’. Both efficiency and sustainability aspects are taken into account. It turns out (a) that durability may be inefficient even in a perfectly competitive economy in which environmental externalities are absent, (b) that in case where markets for product des...
