Two main approaches are commonly used to empirically evaluate linear factor pricing models: regression and SDF methods, with centred and uncentred versions of the latter. We show that unlike standard two-step or iterated GMM procedures, single-step estimators such as continuously updated GMM...

We propose new approaches to test for spanning in the return and stochastic discount factor mean-variance frontiers, which assess if either the centred or uncentred mean and cost representing portfolios are shared by the initial and extended sets of assets. We show that our proposed tests are...

We analyze the effects of the observed increased share of delegated capital for trading strategies and equilibrium prices by introducing delegation into a standard Lucas exchange economy. In equilibrium, some investors trade on their own account, but others decide to delegate trading to...

A methodology is presented allowing manufacturers and retailers vertical contracting in their pricing strategies on a differentiated product market to be introduced. This contribution allows price-cost margins to be recovered from estimates of demand parameters both under linear pricing models...

We present a methodology allowing to introduce manufacturers and retailers vertical contracting in their pricing strategies on a differentiated product market. We consider in particular two types of non linear pricing relationships, one where resale price maintenance is used with two part...

We present the first empirical estimation of a structural model taking into account explicitly the endogenous buyer power of downstream players facing two part tariffs contracts offered by the upstream level. We consider vertical contracts between manufacturers and retailers where resale price...

We provide practical advice for applied economists regarding specification and interpretation of linear regression models with interaction terms.

The political economy of resource rich countries is surveyed. The empirical evidence suggests that countries with a large share of primary exports in GNP have bad growth records and high inequality, especially if the quality of institutions and the rule of law are bad. The economic argument that...

In this paper, we construct a large Bayesian Vector Autoregressive model (BVAR) for the Euro Area that captures the complex dynamic inter-relationships between the main components of the Harmonized Index of Consumer Price (HICP) and their determinants. The model is estimated using Bayesian...

The paper addresses the issue of forecasting a large set of variables using multivariate models. In particular, we propose three alternative reduced rank forecasting models and compare their predictive performance for US time series with the most promising existing alternatives, namely, factor...
