Chinese economic growth has been spectacular in the last 30 years.  We investigate the role of International Joint Ventures with Technology Transfer agreements, an understudied area.  Technology transfer is the traditional mechanism for developing countries to "catch up" and has been a key...

High frequency financial data allows us to learn more about volatility, volatility of volatility and jumps.  One of the key techniques developed in the literature in recent years has been bipower variation and its multipower extension, which estimates time-varying volatility robustly to...

This paper introduces a new class of multivariate volatility models which is easy to estimate using covariance targeting, even with rich dynamics. We call them rotated ARCH (RARCH) models. The basic structure is to rotate the returns and then to fit them using a BEKK-type parameterization of the...

Economic models of reputation make strong assumptions about the information available to players.  In particular, it is assumed that they know the entire history of the game to date.  Such models can seldom reproduce the cycling of reputations we observe in the real world.  We build a model...

We construct a simple probit model of the determinants of real house price slump endings.  We find that the probability of a house price slump ending is higher, the smaller was the pre-slump house price run-up; the greater has been the cumualtive house price decline; the lower are real mortgage...

This paper extends the standard model of bundling to allow products to be substitutes and for products to be supplied by separate sellers.  Whether integrated or separate, firms have an incentive to introduce a bundling discount when demand for the bundle is elastic relative to demand for...

Rational demand for hedging products, where there is a risk of contractual nonperformance, is fundamentally different to that for indemnity insurance.  In particular, optimal demand is zero for infinitely risk averse individuals, and is nonmonotonic in risk aversion, wealth and price.  For...

This paper analyses collusion-proof multilateral insurance contracts between a risk neutral insurer and multiple risk averse agents in an environment of asymmetric costly state verification.  Optimal contracts involve the group of agents pooling uncertainty and the insurer acting as reinsurer...

This paper investigates the interaction between corruption and infrastructure policy reforms.  I construct a simple model to illustrate how both an incerase in regulatory autonomy and privatisation may influence the effect of corruption.  This interaction is then analysed empirically using a...

A common sales tactic is for a seller to encourage a potential customer to make her purchase decision quickly, before she can investigate rival deals in the market.  We consider a market with sequential consumer search in which firms can achieve this either by making an exploding offer (which...
