This paper studies the role of intrinsic motivation, reputation, and reciprocity in driving open source software innovation. Unlike previous literature based on survey data, we exploit the observed pattern of contributions - the .revealed preference. of developers - to infer the underlying...

We introduce a model of product development in a firm. Our model describes the process as a multi-stage contest (i.e., race) with an endogenous length (with one stage or two stages) between two workers. We model the payments to workers from the new product using the normatively appealing Nash...

Interactions between economic development and financial development are studied by looking at the roles of financial institutions in selecting R&D projects (including for both imitation and innovation). Financial development is regarded as the evolution of the financing regimes. The...

How much would output increase if underdeveloped economies were to increase their levels of schooling? We contribute to the development accounting literature by describing a nonparametric upper bound on the increase in output that can be generated by more schooling. The advantage of our approach...

This report provides and interim account of some aspects of research undertaken in to the adoptions and use of the electronic prescription service (EPS) in England. The role of EPS is a fundamentally simple one. It allows the transmission of prescription messages and digitally-signed...

Remote work arrangements and increased virtual communication are commonplace. Particularly in organizations, virtual communication has become an essential tool for collaboration and exchanging information. Virtual communication channels, such as text or video messages, provide different levels...

This paper conducts a broad-based comparison of iterated and direct multi-step forecasting approaches applied to both univariate and multivariate models. Theoretical results and Monte Carlo simulations suggest that iterated forecasts dominate direct forecasts when estimation error is a...

In this paper we specify a multi-factor long-memory process that enables us to estimate the fractional differencing parameters at each frequency separately, and adopt this framework to model quarterly prices in three European countries (France, Italy and the UK). The empirical results suggest...

This paper investigates the limit properties of mean-variance (mv) and arbitrage pricing (ap) trading strategies using a general dynamic factor model, as the number of assets diverge to infinity. It extends the results obtained in the literature for the exact pricing case to two other cases of...
