The authors examine the timing and quality of product introduction in an R&D stopping game, where they allow for horizontal and vertical differentiation in the product market. They observe that discontinuous changes in introduction dates can occur as firms' abilities as researchers change....

We examine the timing and quality of product introduction in an R&D stopping game, where we allow for horizontal and vertical differentiation in the product market. We observe that discontinuous changes in introduction dates can occur as firms' abilities as researchers change. Further, when the...

This paper investigates the effect of market size on innovation activities across different durable good industries in the Chinese manufacturing sector. We use a potential market size measure driven only by changes in the Chinese income distribution which is exogenous to changes in prices and...

Häufig ist zu hören, dass die Industrie ein aussterbender Wirtschaftszweig sei. Die Zukunft gehöre den Dienstleistungen und der Wissensproduktion. Tatsächlich basiert die moderne Ökonomie ganz wesentlich auf Informationstechnologie. Diese bedarf aber der Hardware. Dienstleistungen und...

We study how exploration versus exploitation innovations impact economic growth through a tractable endogenous growth framework that contains multiple innovation sizes, multi-product firms, and entry/exit. Firms invest in exploration R&D to acquire new product lines and exploitation R&D to...

Collective dismissal costs are an important part of employment protection legislation (EPL) and make firms' exit more costly. We show in a model with step-by-step innovations that dismissal costs spur innovation if product markets are not too competitive: technologically more advanced firms...

We present a model in which two of the most important features of the long-run growth process are reconciled: the massive changes in the structure of production and employment; and the Kaldor facts of economic growth. We assume that households expand their consumption along a hierarchy of needs...

Recent empirical studies find vast industry differences in how patent protection influences innovation and growth. An optimization of aggregate growth, therefore, implies the need for a flexible patent regime responding to each industry's characteristics. In practice, sector-specific...

Recent empirical studies suggest a need for a flexible patent regime responding to industry characteristics. In practice, sector-specific modifications of patent strength already exist but lack theoretical foundation. This paper intends to make up for this neglect by scrutinizing in what...
