This paper investigates the research and development activity of heterogeneous and rationally bounded firms. The latter conduct this activity through in-house research and by collecting information originating in other firms’ spillovers. Thus, research and development activity owes both to independent searching and to interaction diffusing information. We study the conditions under which this idiosyncratic effort yields effects that have either local, system-wise negligible impacts or cumulate to generate significant aggregate ones. In the latter case, global effects feed back upon the incentive to innovate and therefore on the strength of local interaction as well as on autonomous research efforts. It is these dynamic forces that we model. We compare cases in which significant aggregate effects do emerge with cases in which they do not and study their outcome on innovation-directed investment and on long-term growth.  相似文献

The future of pensions in Europe   总被引:1,自引:0,他引:1  
Unfunded state pension schemes are projected to become financially unsustainable. This is usually attributed to demographic trends. Yet trends in unemployment and in female labour force participation are quantitatively as important. Improvements in either or both might be sufficient to rescue existing state schemes, especially if combined with an end to the practice of allowing, even after retirement, the value of a pension to rise with national earnings rather than prices.
Attempts at piecemeal reform are important because nothing in economic theory suggests a switch to the alternative, fully funded pensions is desirable. Not only would such a transition be costly, and therefore politically difficult; it also neglects the fact that it makes sense to diversify the retirement portfolio, holding claims both on labour productivity and on capital assets. One can even view pensions as part of a more sophisticated system of intergenerational transfers through which workers finance their earlier education and subsequent retirement.  相似文献

This paper focuses on a specific strategy that developers of mobile applications may use to stimulate demand: The release of updates. We develop a theoretical analysis that shows that developers have incentives to release updates when experiencing a drop in performance. The predictions of the model are then tested using an unbalanced panel of top 1,000 apps in iTunes and Google Play for five European countries. We estimate that while in iTunes the release of an update stimulates a 26% increase in download growth, in Google Play updates play a less significant role. This difference is partly due to systematic differences in apps and in developers operating in the two stores (“selection effect”), and partly to a lack of quality control on apps and updates in Google Play (“quality check effect”). These findings highlight the crucial importance of an appropriate management of updates as well as the relevance of institutional characteristics of the app stores.  相似文献

Consumer satisfaction has been defined as an objective or subjective state variable. This paper presents an emerging view where satisfaction is construed as a subjective process of consumption experience. We examine studies that have explicitly or implicitly explored the conceptual and empirical domain of satisfaction as a multidimensional process of interactions among mental and overt behavior activities unfolding after purchase over time. Using a dynamic, six-dimension process framework we integrate previous, seemingly disjoint research efforts, and derive related research propositions. Issues in researching satisfaction as a process are also discussed.  相似文献

Revisiting EMU's Stability Pact: A Pragmatic Way Forward   总被引:1,自引:0,他引:1  
The Stability and Growth Pact is under fire. Some countriesare meeting major problems in sticking to the rules. Proposalsto reform the Pact or ditch it altogether abound. The allegedweaknesses of the Pact tend to reflect trade-offs typical ofsupra-national arrangements. This aspect has to be factoredin when considering reforms of the current fiscal rules: thereis no miracle solution. EMU without rules would be an interestingexperiment, but a risky policy option. Given the existing degreeof political integration in EMU, internal adjustment ratherthan attempting to redesign the rules from scratch appears amore suitable way forward. Redefining the medium-term budgetarytarget, improving transparency, tackling the pro-cyclical fiscalbias in good times, moving towards non-partisan applicationof the rules, and improving transparency in the data can achieveboth stronger discipline and higher flexibility.  相似文献

In this paper, we focus on the role of persistence and heterogeneity of innovative activities at the level of the firm in determining the patterns of technological change in different industries and countries. We ask: are persistence and heterogeneity associated with higher degrees of concentration in innovative activities, stability in the ranking of innovators, and lower degrees of entry and exit in the population of innovators? Or, do the patterns of innovation depend on other variables like firm size and industrial concentration? Moreover, what are the relationships between the patterns of innovative activities, their determinants, and the technological specialization of countries? We compute indicators of persistence and heterogeneity using the OTAF-SPRU patent database at the firm level for five European countries over the period 1969–1986 for 33 technological classes. Then, we estimate the relationships between our indicators of the sectoral patterns of innovative activities and international technological specialization on the one hand, and our indicators of persistence, heterogeneity and market structure on the other. Results show that persistence and asymmetries are important (and strongly related) phenomena that affect the patterns of innovative activities across countries and sectors, while the role of market structure variables is less clear. Finally, international technological specialization is associated to a competitive core of persistent innovators.  相似文献
