We explore a methodological improvement to the standard dynamic demand model for petrol–a general model which allows for slowly evolving, unobservable habits. If this habit formation model is correct, then standard estimation techniques produce inconsistent estimates. We find price elasticities of -0.13 (short-run) and -0.20 (long-run). Importantly, standard techniques are misleading about the ...

For a stable supply of electricity power plants are required to provide ancillary services in addition to energy production. This paper suggests a solution for optimal bidding strategy for hydroelectric units operating in markets where both energy and ancillary services are priced simultaneously. The model is illustrated on a numerical example of a hydro unit operating in such markets of New Yo...

This paper develops a theoretical framework of consumer learning and product valuation when attending to new information is costly. The key attribute of the model is that agents are unsure what product characteristics are present in a good. In the model increased beliefs that a good contains valuable attributes serves to increase learning and, possibly, willingness to pay for the good. We devel...

In this paper we examine the joint performance of FDI and trade under a full liberalization process consistent with New Trade Theory models. The testing framework consists of the estimation of demand for exports and imports of manufactured goods for a panel containing the majority of the EU countries as well as the US and Japan. The model includes as explanatory factors, not only the traditiona...

This paper provides an estimation and testing framework to identify the source(s) of spuriousness in a large nonstationary panel. This can be determined by two non mutually exclusive causes: pooling units neglecting the presence of heterogeneity and genuine presence of I (1) errors in some of the units. The paper proposes two tests that complement a test for the null of cointegration: one test ...

this study investigates the relationship between market structure and profitability in the iranian manufacturing industries. in this study, raw data based on international standard industrial classification (at four digit code) has been used. fixed effects panel estimation method (based on diagnostic test results) has been chosen for empirical investigation. the result of the study confirms the...

We consider a class of panel tests of the null hypothesis of no cointegration and cointegration. All tests under investigation rely on single-equations estimated by least squares, and they may be residual-based or not. We focus on test statistics computed from regressions with intercept only (i.e., without detrending) and with at least one of the regressors (integrated of order 1) being dominat...

This paper presents results concerning the performance of both single equation and system panel cointegration tests and estimators. The study considers the tests developed in Pedroni (1999, 2004), Westerlund (2005), Larsson, Lyhagen, and Löthgren (2001) and Breitung (2005); and the estimators developed in Phillips and Moon (1999), Pedroni (2000), Kao and Chiang (2000), Mark and Sul (2003), Pedr...
