This paper analyzes peer effects among university scientists. Specifically, it investigates whether the number of peers and their average quality affects the productivity of researchers in physics, chemistry, and mathematics. The usual endogeneity problems related to estimating peer effects are...

The Wong-Viner Envelope Theorem on the equality of long-run and short-run marginal costs (LRMC and SRMC) is reformulated for convex but generally nondifferentiable cost functions. The marginal cost can be formalized as the multi-valued subdifferential a.k.a. the subgradient set but, in itself,...

This paper examines the investment strategies of regulated companies in abatement technologies, market participants' trading behaviors, and the liquidity level in an inter-temporal cap{and{trade market using laboratory experiments. The experimental analysis is performed under varying market...

The recent crisis underlined that proper estimation of distress-dependence amongst banks in a global system is essential for financial stability assessment. We present a set of banking stability measures embedding banks’ linear (correlation) and nonlinear distress-dependence, and their changes...

We investigate the rapid influx of overseas students into UK higher education and the impact on the number of domestic students. Using administrative data since 1994/5, we find no evidence of crowd out of domestic undergraduate students and indications of increases in the domestic numbers of...

Gaps in welfare attainment between boys and girls in China have attracted international attention. In this paper demand analysis is used to try and uncover the factors which may be driving the emergence of the gender gaps. Drawing on household expenditure data from a poor (Sichuan) and rich...

The “short-run approach” calculates long-run producer optima and general equilibria by building on short-run solutions to the producer’s profit maximization problem and on profit-based valuation of the fixed inputs. We outline this method and illustrate it on an example of peak-load pricing.

This paper sheds new light on the subtle relation between probability and logic by (i) providing a logical development of Bruno de Finetti's conception of events and (ii) suggesting that the subjective nature of de Finetti's interpretation of probability emerges in a clearer form against such a...

This paper proposes an approach to proving nonparametric identification for distributions of bidders' values in asymmetric second-price auctions. I consider the case when bidders have independent private values and the only available data pertain to the winner's identity and the transaction...

This paper centres around the question of ownership of firms and managerial competition and how these affect managers and employees’ incentives to invest in human capital. We argue that employees’ incentives in human capital investment are affected by both ownership and competition since...
