Using a stylized two-period model we compare portfolio solutions from two local solution approaches–the approach of Judd and Guu (2001) and the approach of Devereux and Sutherland (2010, 2011)–with the true nonlinear portfolio solution. 相似文献

In the last decade, there has been an increasing interest in the link between new product launch strategy and market performance. So far, new product launch research has focused on this performance relationship without giving much attention to background factors that can facilitate or inhibit successful launch strategies. However, investigating such antecedents that set the framework in which different strategic launch decisions enable or prevent the market performance of new products is useful for enhancing the current state of knowledge. Drawing on the concept of a firm's orientation, the present study discusses the influence of the corporate mind‐set on new product launch strategy and market performance. It is hypothesized that the capability to successfully launch new products is based on the interplay between a firm's mind‐set (i.e., an analytical, risk‐taking, and aggressive posture) and its strategic launch decisions on setting launch objectives, selecting target markets, and positioning the new product. A research model with mediating effects is proposed, where the corporate mind‐set determines the launch strategy decisions, which in turn impact market performance. The model is tested with data on 113 industrial new products launched in business‐to‐business markets in Germany using a multiple informant approach. The results support the mediated model as the dimensions of the corporate mind‐set have a significant impact on most strategic launch decisions, which in turn significantly contribute to market performance. It is found that while an analytical posture relates to all three strategic launch decisions, risk taking and an aggressive posture have a significant impact on two, respectively one, launch strategy elements. These findings confirm the importance of investigating antecedents for a successful new product launch, as the corporate mind‐set serves as a background resource that sets the framework for successful new product launch decisions. In the final section implications for research and managerial practice as well as limitations of this research are provided. 相似文献

When studying individuals, when is the combination of qualitative and quantitative methods better than just one method alone?
Whereas the debate in macro-level research, such as in political science about comparing nations, has made progress in identifying
meaningful logics for a combination of methods, it is yet unclear how these logics can be applied to the study of individuals.
Individual-level dynamics are in tendency less inert than those of nations or organisations. Therefore, a combination of methods
is more difficult to justify in individual-level analysis since differences in measurement results could be due to changes
in the dynamics rather than due to the application of different techniques. In contrast, the assumption of unit homogeneity
seems to be more easily met for individuals than for countries or other higher-level aggregates, facilitating a comparison
of like and like. First, this article presents a compilation of conditions scattered across the literature for the analysis
of individuals, according to which a mixed-method is preferable to a single-method approach. Second, the application of these
conditions is illustrated with an analysis of the impact of intergenerational relationships on welfare state attitudes in
Germany on the basis of survey and focus group data. 相似文献

We report four repetitions of Falk and Kosfeld’s (Am. Econ. Rev. 96(5):1611–1630, 2006) low and medium control treatments with 476 subjects. Each repetition employs a sample drawn from a standard subject pool
of students and demographics vary across samples. We largely confirm the existence of hidden costs of control but, contrary
to the original study, hidden costs of control are usually not substantial enough to significantly undermine the effectiveness
of economic incentives. Our subjects were asked, at the end of the experimental session, to complete a questionnaire in which
they had to state their work motivation in hypothetical scenarios. Our questionnaires are identical to the ones administered
in Falk and Kosfeld’s (Am. Econ. Rev. 96(5):1611–1630, 2006) questionnaire study. In contrast to the game play data, our questionnaire data are similar to those of the original questionnaire
study. In an attempt to solve this puzzle, we report an extension with 228 subjects where performance-contingent earnings
are absent i.e. both principals and agents are paid according to a flat participation fee. We observe that hidden costs significantly
outweigh benefits of control under hypothetical incentives. 相似文献

Are entrepreneurs influenced by risk attitude,regulatory focus or both? An experiment on entrepreneurs' time allocation 总被引:1,自引:0,他引:1
“Hybrid entrepreneurs” — those who maintain a wage job while starting a new enterprise — outnumber pure entrepreneurs in many countries. Yet, how hybrid entrepreneurs allocate their working hours between these two activities is not well understood. To better understand the relationship between hybrid entrepreneurs' division of time between their wage jobs and new enterprises we develop a model that captures hybrid entrepreneurs' decisions on the tradeoffs between financial risk and return as it relates to time allocation. We test two hypotheses based on utility theory, and challenge them with two hypotheses based on regulatory focus theory in a controlled experiment with 25 early stage entrepreneurs and 29 undergraduate students. In the computer-based experiment, entrepreneurs' and students' time allocation decisions (tied to monetary incentives) are used to test what would motivate them to work more or less hours in their entrepreneurial startups. We find that the actual time allocation decisions of the student group are somewhat in tune with utility theory, but that the entrepreneurs' time allocation decisions are better explained by regulatory focus theory. 相似文献

Export Behavior and Firm Productivity in German Manufacturing: A Firm-Level Analysis 总被引:2,自引:0,他引:2
This paper examines the causal relationship between productivity and exporting in German manufacturing. We find a causal link from high productivity to presence in foreign markets, as postulated by a recent literature on international trade with heterogeneous firms. We apply a matching technique in order to analyze whether the presence in international markets enables firms to achieve further productivity improvements, without finding significant evidence for this. We conclude that high-productivity firms self-select themselves into export markets, while exporting itself does not play a significant role for the productivity of German firms. JEL no.

The paper assesses the stability and predictive performance of a European money demand function as compared to national money demand functions. With respect to the explanatory accuracy, the national functions perform better than the aggregated function. Examination of the residuals of the national money demand equations indicates that currency substitution is not the major cause for the stability of the aggregated money demand function. The aggregate relation mainly seems to reflect German money demand. This conclusion is supported by the instability of aggregated money demand resulting from the exclusion of Germany from the aggregate. 相似文献
