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....

German technology policy has undergone a remarkable change during the last years. The first thing to mention is that technology policy in Germany takes a broader view now, focussing not only on knowledge creation (i.e. the invention process per se) but also on knowledge diffusion and faster...

This paper examines the association between the outcome of business incubation and the resources used by incubators, by using a small panel of science and technology business incubators (STBIs) in China. We find that while the number of firms graduating from an STBI is closely correlated with...

Acemoglu, Johnson, Robinson, and Yared (2008) demonstrate that estimation of the standard adjustment model with country-fixed and time-fixed effects removes the statistical significance of income as a causal factor of democracy. We argue that their empirical approach must produce insignificant...

If a product has two dimensions of quality, one observable and one not, a firm can use observable quality as a signal of unobservable quality. The correlation between consumers' valuation of high quality in each dimension is a key determinant of the feasibility of such signaling. A firm may use...

As consumers’ demand for organic products and especially organic food grows, organic certification for tropical fruit is increasingly promoted in many developing countries. Certified organic pineapple exports only started taking off after 2005 and are rapidly increasing. The organic and...

Companies with market power occasionally engage in intentional quality reduction of a portion of their output as a means of offering two qualities of goods for the purpose of price discrimination, even absent a cost saving. This paper provides an exact characterization in terms of marginal...

During the recent decades, multitasking has become a more and more common phenomenon at workplaces. Rather than specializing in a job task, workers perform bundles of tasks. Bundling occurs when tasks are complements. Using individual-level data about job tasks, we analyze which tasks are...

Ex-ante regulations and ex-post liabilities for using a new technology will induce additional costs for adopters. The standard model is advanced by including irreversibility and uncertainty and taking into account transaction costs of negotiating possible cost reductions. The case analysed is...

This paper sheds light on how changes in the organization of work lead to wage inequality. We present a theoretical model in which workers with a wider span of competence (higher level of multitasking) earn a wage premium. Since abilities and opportunities to expand the span of competence are...
