This study tackles the puzzle of why increasing entrepreneurial experience does not always lead to improved financial performance of new ventures. We propose an alternate framework demonstrating how experience translates into expertise by arguing that the positive experience–performance relationship only appears to expert entrepreneurs, while novice entrepreneurs may actually perform increasingly worse because of their inability to generalize their experiential knowledge accurately into new ventures. These negative performance implications can be alleviated if the level of contextual similarity between prior and current ventures is high. Using matched employee–employer data of an entire population of Swedish founder-managers between 1990 and 2007, we find a non-linear relationship between entrepreneurial experience and financial performance consistent with our framework. Moreover, the level of industry, geographic, and temporal similarities between prior and current ventures positively moderates this relationship. Our work provides both theoretical and practical implications for entrepreneurial experience—people can learn entrepreneurship and pursue it with greater success as long as they have multiple opportunities to gain experience, overcome barriers to learning, and build an entrepreneurial-experience curve. 相似文献

Based on the work of Suzuki, we consider a generalization of Merton’s asset valuation approach in which two firms are linked by cross-ownership of equity and liabilities. Suzuki’s results then provide no arbitrage prices of firm values, which are derivatives of exogenous asset values. In contrast to the Merton model, the assumption of lognormally distributed assets does not result in lognormally distributed firm values, which also affects the corresponding probabilities of default. In a simulation study we see that, depending on the type of cross-ownership, the lognormal model can lead to both over- and underestimation of the actual probability of default of a firm under cross-ownership. In the limit, i.e. if the levels of cross-ownership tend to their maximum possible value, these findings can be shown theoretically as well. Furthermore, we consider the default probability of a firm in general, i.e. without a distributional assumption, and show that the lognormal model is often able to yield only a limited range of probabilities of default, while the actual probabilities may take any value between 0 and 1. 相似文献

Kapitel I. Bibliographisches Die versicherungstechnische Litteratur hat sich verhältnismässig wenig mit den aktuariell-finanziellen Fragen befasst. Bemerkenswert ist es deshalb, dass die meisten von den bis jetzt abgehaltenen neun internationalen Aktuarkongressen die eine oder die andere Frage aus oben erwähntem Gebiet in ihrem Programm aufgenommen haben. So z. B. beschäftigte sich der erste Kongress, der 1895 in Brüssel tagte, mit dem Gegenstand: “Des mesures qui pourraient être prises par les institutions qui contractent des engagements à long terme, pour se premunir contre les conséquences des variations du taux d intérêt.” Der Kongress im Jahre 1900 in Paris hatte in seinem Programm das Thema: “Méthodes à employer pour evaluer les titres mobiliers compris dans l'actif d'une Société quelconque.” Bei dem New Yorker Kongress 1903 wurde die Prage über “The Probable Future Course of the Rate of Interest” erörtert. Dem Wiener Kongress 1909 war die Frage über “Kapitalsanlagen der Versicherungsgesellschaften mit besonderer Berücksichtigung der modernen Entwickelung” zur Behandlung vorgelegt. Das Programm des Londoner Kongresses 1927 enthielt das Thema “Currency Depreciation as affecting Life Assurance Contracts”. 相似文献

We consider a robust version of the classic problem of optimal monopoly pricing with incomplete information. In the robust version, the seller faces model uncertainty and only knows that the true demand distribution is in the neighborhood of a given model distribution. We characterize the pricing policies under two distinct decision criteria with multiple priors: (i) maximin utility and (ii) minimax regret. The equilibrium price under either criterion is lower then in the absence of uncertainty. The concern for robustness leads the seller to concede a larger information rent to all buyers with values below the optimal price without uncertainty. 相似文献

The collapse of communism, the success of the US economy and the rise of the internet have led many to argue that the rest of the world should adopt American capitalism. This article uses evidence from the ancient Mediterranean and Middle East to argue that the most successful form of capitalism in each area (and era) depends on the context of the time, the culture of the people and the history of the region. 相似文献

One approach to trade liberalization is the zero-for-zero sectoral approach which involves agreements to eliminate export subsidies, import tariffs, and export taxes in a sector. This article provides an assessment of the impact of border trade liberalization on oilseeds and oilseed products trade. The analysis suggests that under all of the scenarios examined, North American oilseed crushers and oilseed producers gain from trade liberalization. The exact size and the distribution of these gains depends on the number of countries that participate in trade liberalization. The results suggest that the United States and Canada would gain from the adoption of the zero-for-zero proposal. 相似文献

A set of improvements were introduced on a railway line in the south of Sweden in January 1992, including a new train concept, improved timetable and lower fares. The new train replaced a combination of old rail cars and standard coaches (bus). Furthermore, 18 months later, a new high comfort coach (bus) service was introduced as a complement to the train timetable to increase the number of departures. Forecasts from a national four-step model system, based on Revealed Preference data, which did not cover explanatory factors like mode concept, comfort, mode image, was made and compared with a forecast based on stated preference data choice model. Both type of forecasts were compared to travel statistics. Stated Preference data have been collected from car drivers, coach and train passengers. The set of improvements have been included in the SP alternatives presented to the subjects. A structured logit model, a regression model and a linear programming model are compared. Unstructured and structured logit models are compared. Logit models have been estimated and used to form a mode choice model which predicts the changes in market shares between the train and car. The choice model forecast coincide, accidentally, with actual demand 8–9 months after the introduction of the set of improvements (a 40% increase in journeys). The set of improvements, including the new train service, has proven to be a success with more than 100% increase in travel after only two years of operation. Differences in estimated logit models for 1991 and 1992 are explained as partly due to asymmetry effects and partly to shortcomings in the SP data collection technique. Logit model estimates for train and coach are compared. The value of high standard coach service, running in parallel to the train, is estimated. The new coach gained few new passengers and also a much lower monetary value than the train by both train and bus passengers. 相似文献
