We consider partial identification of finite mixture models in the presence of an observable source of variation in the mixture weights that leaves component distributions unchanged, as is the case in large classes of econometric models. We first show that when the number J of component...

In this paper we review the existing empirical literature on price asymmetries in commodities, providing a way to classify and compare different studies which are highly heterogeneous in terms of econometric models, type of asymmetries and empirical findings. Relative to the previous literature,...

In this paper, we explore how competition among stock exchanges, operated as self-regulatory organizations (SROs), affects the design of their members' surveillance. We develop a model where two for-profit SROs compete for trading volume, while brokers execute transactions on behalf of the...

This paper studies the asymptotic relationship between Bayesian model averaging and post-selection frequentist predictors in both nested and nonnested models. We derive conditions under which their difference is of a smaller order of magnitude than the inverse of the square root of the sample...

The paper generalizes the Taylor principle---the proposition that central banks can stabilize the macroeconomy by raising their interest rate instrument more than one-for-one in response to higher inflation---to an environment in which reaction coefficients in the monetary policy rule evolve...

Analizie poddano modele ekonometryczne z parametrami generowanymi przez niestacjonarny proces stochastyczny. Przedstawiono i omówiono trzy konstrukcje (model Cooleya-Prescotta model ze zbieżnymi parametrami Rosenberga, oraz model z filtrami Kalmana). Podano obszerną listę...

The purpose of this paper is to introduce a modification of a standard four input production process where energy is used in an inefficient way due to partly unnecessary waste of energy. In this production process, R&D investment is an additional input in order to improve energy efficiency. It...

While it is widely believed that bribery is ubiquitous among Asian firms, few studies have offered systematic evidence of such activities, and the dynamics of bribery in Asian firms have not been well understood. The research reported here used World Business Environment Survey (WBES) data to...

Simulation estimators, such as indirect inference or simulated maximum likelihood, are successfully employed for estimating stochastic differential equations. They adjust for the bias (inconsistency) caused by discretization of the underlying stochastic process, which is in continuous time. The...

Health economic evaluation has become increasingly important in medical research and recently has been built on solid statistical and decision-theoretic foundations, particularly under the Bayesian approach. In this article we review the basic concepts and issues associated with the statistical...
