The transitional dynamics for both a developed and a less developed country are derived when North-South trade leads to technological diffusion through reverse engineering of intermediate goods in a quality ladder model of endogenous growth. Domestic technological progress occurs via innovation...

It is becoming increasingly clear that the evaluation of policy measures that affect the growth performance of the economy requires adequate treatment of their effects on technological change. Environmental policy and regulations fit in this category. In this paper, I study the effects of taxes...

In industrial economies, firms build their market position by consistently investing in R&D over time and accumulating knowledge protected by secrecy, patents and other appropriability devices. To explore the macroeconomic implications of this fact, I construct an economy where oligopolistic...

To account for the qualitative differences between developed and developing countries, this paper argues that the expensive in-house R&D that manufacturing firms undertake in advanced industrial economies cannot be supported in countries that are in the early stage of industrialization and do...

We develop a dynamic general equilibrium model of capital accumulation where credit is intermediated by banks operating in a Cournot oligopoly. The number of banks affects capital accumulation through two channels. First, it affects the quantity of credit available to entrepreneurs. Second, it...

Evidence shows that firms build their market position by accumulating knowledge protected by secrecy, patents and other appropriation devices. I explore the implications of this fact in a model economy where oligopolistic firms establish in-house R&D programs. In symmetric equilibrium, the...

In the early stage of western industrialization, innovation was the domain of individuals who devoted their entrepreneurial talents to the development of a new product or process, typically setting up a new firm in order to take the innovation to the market. Today, commercial R&D is almost...

Unemployment occurs when some agents, say unions, have control over the wage and set it above the market-clearing level. In other words, it is generated by their exercise of market power. What if, in addition, firms have control over prices in the product market? In this case, market power of...
