Offering a unifying theoretical perspective not readily available in any other text, this innovative guide to econometrics uses simple geometrical arguments to develop students' intuitive understanding of basic and advanced topics, emphasizing throughout the practical applications of modern theory and nonlinear techniques of estimation. One theme of the text is the use of artificial regressions for estimation, reference, and specification testing of nonlinear models, including diagnostic tests for parameter constancy, serial correlation, heteroscedasticity, and other types of mis-specification. Explaining how estimates can be obtained and tests can be carried out, the authors go beyond a mere algebraic description to one that can be easily translated into the commands of a standard econometric software package. Covering an unprecedented range of problems with a consistent emphasis on those that arise in applied work, this accessible and coherent guide to the most vital topics in econometrics today is indispensable for advanced students of econometrics and students of statistics interested in regression and related topics. It will also suit practising econometricians who want to update their skills. Flexibly designed to accommodate a variety of course levels, it offers both complete coverage of the basic material and separate chapters on areas of specialized interest.

Estimation and Inference in Econometrics

Good corporate reputations are critical because of their potential for value creation, but also because their intangible character makes replication by competing firms considerably more difficult. Existing empirical research confirms that there is a positive relationship between reputation and financial performance. This paper complements these findings by showing that firms with relatively good reputations are better able to sustain superior profit outcomes over time. In particular, we undertake an analysis of the relationship between corporate reputation and the dynamics of financial performance using two complementary dynamic models. We also decompose overall reputation into a component that is predicted by previous financial performance, and that which is ‘left over’, and find that each (orthogonal) element supports the persistence of above-average profits over time.

Corporate reputation and sustained superior financial performance

The theory of precautionary saving is shown in this paper to be isomorphic to the Arrow-Pratt theory of risk aversion, making possible the application of a large body of knowledge about risk aversion to precautionary saving, and more generally, to the theory of optimal choice under risk In particular, a measure of the strength of precautionary saving motive analogous to the Arrow-Pratt measure of risk aversion is used to establish a number of new propositions about precautionary saving, and to give a new interpretation of the Oreze-Modigliani substitution effect

Precautionary Saving in the Small and in the Large

Despite the wide use of reputational mechanisms such as eBay's Feedback Forum to promote trust, empirical studies have shown conflicting results as to whether online feedback mechanisms induce trust and lead to higher auction prices. This study examines the extent to which trust can be induced by proper feedback mechanisms in electronic markets, and how some risk factors play a role in trust formation. Drawing from economic, sociological, and marketing theories and using data from both an online experiment and an online auction market, we demonstrate that appropriate feedback mechanisms can induce calculus-based credibility trust without repeated interactions between two transacting parties. Trust can mitigate information asymmetry by reducing transaction-specific risks, therefore generating price premiums for reputable sellers. In addition, the research also examines the role that trust plays in mitigating the risks inherent in transactions that involve very expensive products.

Evidence of the effect of trust building technology in electronic markets: price premiums and buyer behavior

Many have speculated that trust plays a critical role in stimulating consumer purchases over the Internet. Most of the speculations have rallied around U.S. consumers purchasing from U.S.–based online merchants. The global nature of the Internet raises questions about the robustness of trust effects across cultures. Culture may also affect the antecedents of consumer trust; that is, consumers in different cultures might have differing expectations of what makes a web merchant trustworthy. Here we report on a cross-cultural validation of an Internet consumer trust model. The model examined both antecedents and consequences of consumer trust in a Web merchant. The results provide tentative support for the generalizability of the model.

Consumer Trust in an Internet Store: A Cross‐Cultural Validation

The absolute and relative impact of current quality and reputation variables on consumer decisions are examined using data from the market for Bordeaux wine. The estimates indicate that a model of consumer decision making which incorporates information on reputation (past quality) and collective reputation (average group quality) rejects alternative models that include current quality. The results also indicate that reputation has a large impact on the willingness to pay of consumers, that long term reputation is considerably more important than short term quality movements, and that consumers react slowly to changes in product quality. Collective reputation is shown to have an impact on consumer willingness to pay that is as large as that of individual firm reputation. If reputation and collective reputation effects are ignored, the estimated impact of current quality and short term changes in quality on consumer behaviour are overstated.

The Use of Quality and Reputation Indicators by Consumers: The Case of Bordeaux Wine

The impact on price of current product quality and reputation are estimated using data from the market for Bordeaux wine. A model is proposed in which price is a function of current quality and expected quality, where the latter depends on reputation. Equations determining price and expected quality are estimated jointly. The empirical findings show that the price premium associated with better individual and collective (or group) reputation far exceeds that associated with improvements in current quality. As well, the market values collective reputation indicators only to the extent that they are useful predictors of product quality.

Stock markets and the exchange rate: A multi-country approach☆

Estimates are presented for the impact of debt accumulation by the central and subcentral governments of a federation on the creditworthiness of other federation member governments. The estimates, calculated using an ordered probit model and Canadian provin- cial data, indicate that debt accumulation by the central government has reduced the credit- worthiness of indebted provincial governments. Interprovincial debt accumulation effects are negative but relatively small, except for the debt of the largest province, which has a strong positive effect on the creditworthiness of the other provinces. These findings may have
