This paper provides nonparametric identification results for a class of latent utility models with additively separable unobservable heterogeneity. These results apply to existing models of discrete choice, bundles, decisions under uncertainty, and matching. Under an independence assumption,...

The source code of the package tvReg is publicly available for download from the Comprehensive R Archive Network. The five basic functions in this package are the tvLM, tvAR, tvSURE, tvPLM, tvVAR and tvIRF, which cover a large range of semiparametric models with time-varying coefficients....

Spanish Abstract: En este documento se presenta un análisis de la causalidad entre el crecimiento del producto por trabajador y la inversión en capital físico por trabajador. Mediante la metodología de los modelos de Vectores Autorregresivos (VAR) se desarrolla una evaluación empírica para...

In this paper, we analyse the determinants of gold prices in the Turkish free market using classic linear regression techniques. We modeled the gold price movement using two static models, a simple linear and a polynomial of degree three. We compared two models and concluded that third degree...

The paper lists salient characteristics of the certainty theory of consumer choice and discusses the import of prominent empirical analyses of the theory. All of them reject the theory's empirical relevance which suggests that the theory is unfit to analyze consumer choice in an uncertain world....

This paper analyzes Structural Vector Autoregressions (SVARs) where identification of structural parameters holds locally but not globally. In this case there exists a set of isolated structural parameter points that are observationally equivalent under the imposed restrictions. Although the...

An algorithm is developed for the empirical selection of valid instrumental variables based on graph-theoretic causal search (or Bayes-net) methodologies for directed cyclical graphs. The method also helps to identify causal structure when the underlying relationships are simultaneous or...

This paper analyzes Structural Vector Autoregressions (SVARs) where identification of structural parameters holds locally but not globally. In this case there exists a set of isolated structural parameter points that are observationally equivalent under the imposed restrictions. Although the...

The paper begins with a figurative representation of the contrast between present-day and formal applied econometrics. An explication of the status of bridge principles in applied econometrics follows. To illustrate the concepts used in the explication, the paper presents a simultaneous-equation...

The seminal work by Baumol et al. (1982) has highlighted the importance of analyzing firms' costs structure. This allows to design proper policy measures and to understand the impacts of those policies in markets. The note presents an original method and an application for testing costs...
