An omitted variable in the household's preferences specification may lead to overestimate the volatility of consumption, or alternatively to overvalue the risk aversion coefficient required to match the equity premium. This paper proposes to augment the utility function by adding a nontradable...

This paper considers structural nonparametric random utility models for continuous choice variables. It provides sufficient conditions on the structural model to yield reduced-form systems of nonparametric stochastic demand functions that constitute a global homeomorphism between demands and...

This paper considers parametric estimation problems with i.i.d. data. It focusses on rate-efficiency, in the sense of maximal possible convergence rates of stochastically bounded estimators, as an optimality criterion, largely unexplored in parametric estimation. Under mild conditions, the...

The literature on unemployment dynamics is mainly concerned with the nature and impact of shocks to unemployment. In this paper we use OECD unemployment data to infer the nature of these shocks using factor analysis. We find that two Principal Components can account for a large part of the...

This paper explores the relationship between imports of services by the United States and the international sourcing of services production activities using a number of different panel data estimators for a number of different categories of services. A conventional import demand relationship is...

This paper analyzes equilibria in sequential take-it-or-leave-it sales and sequential auctions when demand is stochastic. It is shown that equilibria in the former mechanism trade-off allocative efficiency and competing buyers' opportunities to acquire an item to be sold, permitting prices and...

The linkage between stock market and aggregate consumption has been extensively studied in the context of linear econometric models. This paper proposes a less restrictive approach: short-run dynamics in US consumption are analysed applying semi-parametric techniques to a large sample of monthly...

Recently, the large T panel literature has emphasized unobserved, time-varying heterogeneity that may stem from omitted common variables or global shocks that affect each individual unit differently. These latent common factors induce cross-section dependence and may lead to inconsistent...

We consider a service system (Qs) that operates according to the FCFS discipline, and in which the service rate is an increasing function of the queue length. Customers arrive sequentially to the system and decide whether or not to join, using decision rules based upon the queue length on...

In a dynamic optimising model with costly tax collection, a tax cut by one nation creates positive externalities for the rest of the world if initial public debt stocks are positive. By reducing tax collection costs, current tax cuts boost the resources available for current private consumption,...
