Cobb Douglas production function parameters are not identified from cross-section variation when inputs are perfectly flexible and chosen optimally, and input prices are common to all firms. We consider the role of adjustment costs for inputs in identifying these parameters in this context. The...

Schooling is typically found to be highly correlated with individual earnings in African countries.  However, African firm or sector level studies have failed to identify a similarly strong effect for average worker schooling levels on productivity.  This has been interpreted as evidence that...

This paper develops a sequential learning estimator of production functions and productivity dynamics for unbalanced establishment panels. Extending an idea from the literature on dynamic industry models, establishments are uncertain about their own idiosyncratic productivities and update...

We develop a model in which cash-constrained entrepreneurs seek a venture capitalist (VC) to finance a new firm. Costly monitoring is employed by VCs to reduce entrepreneurial moral hazard. When monitoring reveals poor performance, VCs want to punish the entrepreneur with liquidation. However,...

We present a model of cash constrained entrepreneurs who need an investor to finance their project. Investors can either be uninformed, such as individual bondholders, or informed, such as venture capitalists and banks. There is an entrepreneurial moral hazard problem, which can be partially...

We study two platforms competing for members by investing in network quality.  Quality is complementary to the network size: the marginal utility generated by an additional member increases with the network's quality.  Platforms are imperfect substitutes: a share of the potential members are...

This paper analyses the survival of the complete cohort of more than 162,000 limited companies incorporated in Britain in 2001 over the subsequent five-year period.  For this purpose, we estimate firms' hazards of failure and survival functions using nonparametric and semi-parametric...

We construct a unique panel dataset to examine how R&D and intellectual property (IP), via patents and trade marks, increase firm productivity. Knowledge has public good characteristics of non-depletability and non-excludability. Even with IP, imitation and inventing around other firm`s products...

Three dimensions of the performance of firms in Ghana’s manufacturing sector are investigated in this paper: their technology and the importance of technical and allocative efficiency. We show that the diversity of factor choices is not due to a non-homothetic technology....
