This paper examines how firm characteristics and local anti‐corruption effort moderate the influence of political connections on enterprises’ private R&D investment using data from 2,587 Chinese A‐share listed enterprises. Our results show that the local anti‐corruption institutional environment significantly moderates the strong relationship between political connections and enterprises’ private R&D investment. Firm characteristics (i.e., firm size and firm age) also show a moderating effect on the relationship between political connection and enterprises’ private R&D investment; larger and older enterprises are more likely to have innovative resources and business cooperation partners, and thus are able to reduce their degree of reliance on political connections and government funding. The results of our study suggest the importance of having a transparent and fair institutional environment for enterprise innovation activities. 相似文献

Identifying the value orientations of subjects participating in market or non-market decisions by having them participate in a ring game may be helpful in understanding the behaviour of these subjects. This experiment presents the results of changes in the centre and the radius of a value orientations ring in an attempt to discover if the measured value orientations exhibit income or displacement effects. Neither significant income effects nor displacement effects are identified. An external validity check with a voluntary contribution game provides evidence that value orientations from rings centred around the origin of the decision-space explain significant portions of voluntary contributions while value orientations from displaced rings do not. 相似文献

Mix the wisdom of internal and external networks and you might just come up with brilliant and unexpected solutions to apparently intractable problems. Julian Birkinshaw and Stuart Crainer report on how Roche Diagnostics is exploring an experimental approach to harvesting bright ideas. 相似文献

This paper proposes that customers often respond to brand extension concepts by visualizing the product. We call this process
spontaneous visualization and suggest that it precedes concept evaluations. In two studies, we show that spontaneous visualization
is enhanced by the fit between the parent brand and the extension category and by the ease with which the product category
can be imagined. The appeal of the visualized image in turn determines whether visualization enhances or decreases concept
evaluations. In addition, we find a stronger link between product evaluations and delayed choice when evaluations are based
on visualization; evaluations based on visualization hence appear to be more “valid” in the sense of predicting subsequent
behavior. Implications of these findings and ideas for future research are discussed.

The generation of new markets is an emerging area of interest among researchers working in the traditions of evolutionary
economics. And true to those traditions, the current study incorporates empirical evidence from psychology and cognitive science
to develop micro-foundations for evolutionary theories of new market generation. In this paper we present an in-depth analysis
of how expert entrepreneurs use effectual logic to conceptualize the creation of new markets. Our results challenge received
wisdom based on search and selection processes and move beyond combinatorial ideas to develop instead a “transformational”
view of market genesis. 相似文献

AbstractAims: For this economic analysis, we aimed to model: (1) the cost-efficiency of prophylaxis with biosimilar pegfilgrastim-bmez for chemotherapy-induced (febrile) neutropenia (CIN/FN) compared to reference pegfilgrastim, and (2) the expanded access to CIN/FN prophylaxis and anti-neoplastic treatment that could be achieved with biosimilar cost-savings on a budget-neutral basis.Methods: In a hypothetical panel of 20,000 cancer patients receiving CIN/FN prophylaxis and using the average sales price (ASP) for the second quarter of 2019 for reference pegfilgrastim, we: conducted an ex ante simulation from the payer perspective of the cost-savings of 10–100% conversion from reference to biosimilar pegfilgrastim-bmez using drug price discounting ranging from 10–35%; estimated the budget-neutral expanded access to biosimilar pegfilgrastim-bmez enabled by these cost-savings; and estimated the budget-neutral expanded access to anti-neoplastic treatment with pembrolizumab. The simulations were replicated using fourth quarter 2019 wholesale acquisition cost (WAC) for reference pegfilgrastim and biosimilar pegfilgrastim-bmez in a post facto analysis.Results: In ASP simulations, cost-savings of using pegfilgrastim-bmez over reference pegfilgrastim in a 20,000 patient panel range from $1.3?M (at 15% price discount) to $3?M (35%) at 10% conversion rate and from $6.4?M to $14.9?M, respectively, at 50% conversion. These savings could provide prophylaxis with pegfilgrastim-bmez to an additional 352 (15% discount) to 1,076 patients (35%) at 10% conversion or 1,764–5,384, respectively, at 50% conversion. Alternatively, savings could be reallocated for anti-neoplastic treatment with pembrolizumab to 3 (15% discount) to 9 (35%) patients at 10% conversion or 19–45, respectively, at 50% conversion. When utilizing WAC, cost-savings range from $4.6?M (10% conversion) to $23.1?M (50%) which could provide pegfilgrastim-bmez to an additional 1,174 (10% conversion) to 5,873 patients (50%).Conclusions: Prophylaxis with biosimilar pegfilgrastim-bmez increases the value of cancer care by generating significant cost-savings that could be reallocated to provide expanded access to CIN/FN prevention and anti-neoplastic therapy on a budget-neutral basis. 相似文献

Much of the mainstream literature on macroeconomic policy proceeds by making assertions about the relative efficiency of governments and markets. All too often coordination is assumed to be performed by some mythical deus ex machina, such as the Walrasian auctioneer or a benevolent and more or less omniscient government. The limitations of this approach and the sterile debate to which it gives rise are illustrated and examined in sections 2 and 3. To overcome this problem the relative efficiency of alternative government and non-government allocation and coordination mechanisms need to be analysed explicitly. Section 4 provides a simple illustrative sketch of this approach. 相似文献

This study investigates supply-side investments in the tourism sector, analysing the return and risk relationship of investments in tourism across several countries. The performance of tourism sector companies listed on the stock exchange, for the top one dozen countries according to the World Economic Forum (WEF) tourism rankings, is investigated by region, across these countries and within each country by comparison to other sectors. Several metrics are used to compare the risk-adjusted returns, over a 15-year period ending March 2007 and sub-periods to check the persistence of performance over time. The results present a strikingly different ranking than those of the WEF. The implications for the flow of investment funds are of importance in a global capital market. Money will flow to those investments with the highest expected returns for a given risk level and this has consequential impacts for economic growth and employment in the tourism sector. 相似文献
