Sunk costs for R&D are an important determinant of the level of innovation in the economy. In this paper I recover them using a Markov equilibrium framework. The contribution is twofold. First, a model of industry dynamics which accounts for selection into R&D, capital accumulation and...

We examine the relationships between productivity growth, IT investment and organisational change (∆O) using UK firm data. Consistent with the small number of other micro studies we find (a) IT appears to have high returns in a growth accounting sense when ∆O is omitted; when ∆O is included...

Using a dynamic model of a step-by-step innovation race between financially constrained firms, I study how financial constraints affect innovation activity. The novel theoretical results derive from an analysis of the interaction between the incentive effect of competition on innovation and the...

Economists have long puzzled over the astounding differences in productivity between firms and countries. For example, looking at disaggregated data on U.S. manufacturing industries, Syverson (2004a) found that plants at the 90th percentile produced four times as much as the plant in the 10th...

An expert must train a novice. The novice initially has no cash, so he can only pay the expert with the accumulated surplus from his production. At any time, the novice can leave the relationship with his acquired knowledge and produce on his own. The sole reason he does not is the prospect of...

This paper provides a comprehensive description of the financial environment for households and small businesses in a defined geographical region. It develops a new, functional approach to financial access surveys, which involves asking detailed questions about how respondents meet their...

This paper shows that increasing product market competition can have a direct impact on the employment relationship and on wage inequality. I develop a simple model in which an increase in product market competition increases returns to skill through the effect of competition on the sensitivity...

We model the coordination of specialised tasks inside an organisation as "attribute matching". Using this method, we compare the performance of organisational forms (M-form and U-form) in implementing changes such as innovation and reform. In our framework, organisational forms affect the...

We analyze the contracting structure in a moral hazard setting with several agents where output is produced jointly and is the only contractible variable. Since the salary of each agent is a function of all agents efforts, a positive externality arises between them. This externality is not...

We are concerned with the design of a constitution for a firm - an ex ante contract which assigns residual rights of control (and possibly residual income rights) without reference to the issue to be decided. We focus attention on two polar constitutions: non-profit cooperatives and outside...
