Acquisition of innovative firms is a widely observed phenomenon in high-tech industries. On the basis of distinct advantages of large and small firms, in this paper, we build a tournament model with possible acquisition activity of large firms to derive hypotheses on interdependencies between acquisition frequency and post-acquisition success rates. We find empirical support for our hypotheses that (1) acquisitions increase overall innovation output and (2) that the number of acquisitions is higher in industries with larger heterogeneity between established firms and young start-ups. However, our third hypothesis derived from the formal model that innovation success following from acquisitions varies across industries is only partially confirmed. 相似文献

Risk preferences related to accidents or other situations involving the possibility of multiple fatalities were studied in 87 persons in Sweden belonging to two separate groups with professional or educational knowledge of risk‐ and crisis‐management issues. Use was made of a tradeoff method, the results obtained consisting of von Neuman–Morgenstern utility functions over the range of 0–1000 fatalities. Most of the utility curves for the number of fatalities were found to be convex, implying the majority of subjects to display risk‐seeking behaviour. Implications of the findings for societal risk decision making are discussed, along with prospective areas of application and the possibilities of considering other dimensions than the number of fatalities. 相似文献

Policy makers rely on a mix of government spending and tax cuts to address the imbalances in the economy during an economic crisis, by promoting price stability and renewed economic growth. However, little discussion appears to focus explicitly on quantifying the cost of economic crises in terms of human lives, especially the lives of the most vulnerable members of society, infants. Using a statistical approach that is robust to the increases of mortality in outlying years, we quantify the effect that economic crises, periods of prolonged economic recession, have on infant mortality. Moreover, we investigate whether different levels of public spending on health across advanced industrialized democracies can mitigate the impact of crises on infant mortality. We find that economic crises are extremely costly and lead to a more than proportional increase in infant mortality in the short-run. Substantial public spending on health is required in order to limit their impact. 相似文献

This paper explores the properties of jackknife methods of estimation in stationary autoregressive models. Some general results concerning the correct weights for bias reduction under various sampling schemes are provided and the asymptotic properties of a jackknife estimator based on non-overlapping sub-samples are derived for the case of a stationary autoregression of order p when the number of sub-samples is either fixed or increases with the sample size at an appropriate rate. The results of a detailed investigation into the finite sample properties of various jackknife and alternative estimators are reported and it is found that the jackknife can deliver substantial reductions in bias in autoregressive models. This finding is robust to departures from normality, ARCH effects and misspecification. The median-unbiasedness and mean squared error properties are also investigated and compared with alternative methods as are the coverage rates of jackknife-based confidence intervals. 相似文献

We demonstrate that Rybczynski's classic comparative statics can be reversed in a Heckscher-Ohlin world when preferences in each country favor the exported commodity. This taste bias has empirical support. An increase in the endowment of a factor of production can lead to an absolute curtailment in the production of the commodity using that factor intensively, and an absolute expansion of the commodity using relatively little of the same factor. This outcome - which we call “Reverse Rybczynski” - implies immiserizing factor growth. We present a simple analytical example that delivers this result with unique pre- and post-growth equilibria. In this example, production occurs within the cone of diversification, such that factor price equalization holds. We also provide general conditions that determine the sign of Rybczynski's comparative statics. 相似文献
