This research is an event study that deals with shareholder reaction to the announcement of the merger of two bank holding companies (BHC). The work spans the time period 1980-1987. The period was chosen because of its correspondence with significant deregulation of the industry and significant swings in economic activity. The changing economic activity during the period allowed the study of th...

In this lecture I want to briefly describe some techniques for evaluating dynamic econometric models like the models for gasoline demand you have been estimating. Until now, we have implicitly assumed that these models satisfied the classical assumptions of the Gaussian linear model. In particular, we have assumed that the error sequences {ut} were iid and approximately Gaussian, thus justifyin...

The forecasts accuracy evaluation became a constant preoccupation of specialists in forecasting, because of the failure of predictions that caused the actual economic crisis. The objective of this research is to model and predict some economic variables corresponding too few macroeconomic blocks for Romanian economy. The forecast method is represented by econometric models. Moreover, the accura...

Due to the mispricing of options, no-arbitrage condition put-call parity (PCP) violations lead to inefficiency in the currency options market. Through transaction costs, the effects of these violations are reduced to negligible levels, indicating that PCP is not a sufficient condition for an options market efficiency test. Thus, this study developed a transaction cost-adjusted put-call parity (...

“The preparation of essentially descriptive accounts of immigration into particular countries, together with indications of the supposed effects produced by this immigration, entails little difficulty. Much difficulty, however, besets attempts to isolate and evaluate with precision specific effects, economic and otherwise, produced in countries of immigration by foreign-born individuals who cam...

This study examines three alternative models of correcting for heteroskedasticity in wheat yield: the time trend variance, the GARCH, and an econometric model that includes the potential sources of heteroskedasticity. Nonnested test results suggest that modeling the sources of heteroskedasticity is the preferred procedure. Including potential sources of heteroskedasticity as explanatory variabl...

The purpose of this paper is to try and identify some of the factors behind the comparatively poor R&D performance of the UK in the 1990s, a decade when R&D intensity in the business sector declined consistently. We estimate an econometric model of R&D expenditure using a panel of UK manufacturing industries. Our results highlight the importance of industry characteristics such as sales and pro...

We review the econometric literature on measuring the returns to R&D. The theoretical frameworks that have been used are outlined, followed by an extensive discussion of measurement and econometric issues that arise when estimating the models. We then provide a series of tables summarizing the major results that have been obtained and conclude with a presentation of R&D spillover returns measur...

More than thirty years ago Milton Friedman proposed a `plucking' model of business °uctuations in which output cannot exceed a ceiling level, but will, from time to time, be plucked downward by recession. The model implied that business °uctuations are asymmetric, that recessions have only a temporary e®ect on output, and that recessions are duration dependent while expansions are not. Subseque...

I their article, “Structural Modeling in Marketing: Review and Assessment,” Chintagunta, Erdem, Rossi, and Wedel (2006) provide a comprehensive survey of the contributions to the empirical marketing literature made by researchers using structural econometric modeling. More importantly, their review poses the question of whether structural methods should become more prominent in marketing resear...
