The Influence of Teaching on Research in Economics

An extensive literature in education shows little relationship between teaching and research. Authors advance the notion that research enhances teaching, but they typically ignore the prospect of teaching enhancing research. We report the results of a survey of active researchers in economics who were asked if they could cite a specific instance in which their research was substantively influenced by their teaching. About 50% reported such an experience, with a further 35% indicating, without prompting, that their teaching had a very positive effect on their research in general. Their comments identify a variety of channels through which teaching influences research.     

Predicting Business Failures in Canada*

Empirical researchers and practitioners frequently use the bankruptcy prediction models developed by Altman (1968) and Ohlson (1980). This poses a potential problem for practitioners in Canada and researchers working with Canadian data because the Altman and Ohlson models were developed using U.S. data. We compare Canadian bankruptcy prediction models developed by Springate (1978), Altman and Levallee (1980), and Legault and Véronneau (1986) against the Altman and Ohlson models using recent data to determine the robustness of all models over time and the applicability of the Altman and Ohlson models to the Canadian environment. Our results indicate that the models developed by Springate (1978) and Legault and Véronneau (1986) yield similar results to the Ohlson (1980) model while being simpler and requiring less data. The Altman (1968) and Altman and Levallee (1980) models generally have lower performance than the other models. All models have stronger performance with the original coefficients than with re‐estimated coefficients. Our results regarding the Altman and Ohlson models are consistent with Begley, Ming, and Watts (1996), who found that the original version of the Ohlson model is superior to the Altman model and is robust over time. Les chercheurs empiriques et les praticiens ont souvent recours aux modèles de prédiction des faillites élaborés par Altman (1968) et Ohlson (1980). Or, le fait que ces auteurs aient utilisé des données des États‐Unis dans l'élaboration de leurs modèles soulève un problème particulier pour les praticiens canadiens et les chercheurs qui traitent des données canadiennes. Les auteurs comparent les modèles canadiens de prédiction des faillites mis au point par Springate (1978), Altman et Levallée (1980) et Legault et Véronneau (1986) aux modèles proposés par Altman et Ohlson, en se servant de données récentes pour évaluer la robustesse de tous ces modèles dans le temps et l'applicabilité des modèles d'Altman et Ohlson au contexte canadien. L'analyse révèle que les modèles de Springate (1978) et de Legault et Véronneau (1986) produisent des résultats similaires à ceux du modèle d'Ohlson (1980), bien qu'ils soient plus simples et exigent moins de données. De façon générale, les modèles d'Altman (1968) et d'Altman et Levallee (1980) sont moins performants que les autres modèles. Tous les modèles sont plus efficaces lorsqu'ils font usage des coefficients initiaux que lorsqu'ils sont appliqués à de nouvelles estimations des coefficients. Les résultats obtenus en ce qui a trait aux modèles d'Altman et d'Ohlson corroborent ceux de Begley, Ming et Watts (1996) qui constatent que la version initiale du modèle d'Ohlson est supérieure au modèle d'Altman et résiste au passage du temps.     

London bus tendering: the impact on costs

Bids for cost contracts in London Regional Transport bus routes between 1986 and 1993 are analysed for three purposes: to estimate costs for different types of bus operation; to test hypotheses about bidding under competition; to estimate cost savings attributable to tendering. There is no statistically significant difference in costs of operation between public and private sector operators on the tendered network. Bidding behaviour conforms to some features predicted by theoretical models. The estimated cost saving from tendering is 20%.     

The Effect of Trade Unions on the Provision of Training: Australian Evidence

This paper uses data from the Australian Workplace Industrial Relations Survey conducted in 1989–90 to examine the net impact of trade unions on the extent of formal types of employer-provided training. A net positive effect is found, but only where unions are active in the workplace and not merely de jure representatives of the work-force. The results also indicate, with respect to in-house training, that unions shift the emphasis towards work-forces with long tenure, a finding that is consistent with 'union voice' arguments.     

Shaping of Strategic Behavior: How Macro-Environmental Effects Pattern the Country-Level Participation of Non-US Firms in US Equity Markets

This paper examines the effects of macro-environmental variables on country-level patterns of participation by firms on the US NASDAQ stock exchange. NASDAQ's popularity can be linked to the strength of its technological system, as well as the high frequency of listings of technology-oriented firms. Using concepts from organization theory, strategy and international business, we consider the impact of political, legal, cultural, and colonial heritage status on the strategic capital-seeking behavior of non-US companies in US markets. We empirically demonstrate that similarity in legal systems and a shared colonial heritage will influence the probability of a non-US country having firm participation on the NASDAQ. The results also indicate that the effects of institutional forces are not static processes     

The Association between Trading Recommendations and Broker-Analysts' Earnings Forecasts

This study examines analyst forecast errors within the context of stock recommendations. We predict positive forecast error (i.e., optimism) for buy recommendations and negative forecast error (i.e., pessimism) for sell recommendations. We offer two explanations for this prediction: (1) the unconscious tendency to process information in a manner that supports one's goal, which we refer to as the "objectivity illusion" hypothesis, and (2) the economic incentive to boost trade, which we refer to as the "trade boosting" hypothesis. The pattern of analyst forecast bias we predict (i.e., optimism for buys and pessimism for sells) is opposite in direction to that predicted by the management relations hypothesis—a commonly cited hypothesis for analyst forecast bias.
We find broker-analyst earnings forecast errors are significantly optimistic for buy recommendations and significantly pessimistic for sell recommendations, consistent with the objectivity illusion and trade boosting hypotheses. Our study indicates that the pattern of results reported in prior research (i.e., increasingly optimistic earnings forecasts as the stock recommendation becomes less favorable) is likely driven by a correlated omitted variable, actual earnings. Results of an analysis to distinguish between trade boosting and objectivity illusion appear more consistent with the objectivity illusion.     

A Political Economic Analysis of U.S. Rice Export Programs to Japan and South Korea: A Game-Theoretic Approach

The Uruguay Round Agreement on agriculture has contributed to the increase in U.S. and world rice trade since 1994. Despite this, the Japanese and Korean rice markets continue to be characterized by high levels of trade intervention. This article attempts to analyze both import markets incorporating econometric estimates and public choice theory in a game-theoretic framework. Various scenarios are analyzed. The results show that the overall Nash equilibrium occurs with a 4% tariff reduction for Japan and Korea under the U.S. Market Development Program, which includes the Market Access Program and Foreign Market Development Program.
