The diversity in innovation patterns across manufacturing and service industries and in their outcomes in terms of hourly labor productivity are investigated in this article considering six European countries. The Schumpeterian insights into the variety of innovation are developed in this work by identifying different innovation–performance relationships for industries and countries, relying either on the dominant role of product innovation, or on the diffusion of process improvements. Moreover, the “push” effect of innovation is combined with the “pull” effect of demand, by considering the impact of the dynamics of consumption and investment at the sectoral level. The results point out a “North-South” divide across EU countries, with the three countries of Northern Europe closely associated to the model of productivity growth based on product innovation, and the three Southern countries, mainly relying on the mechanisms by which process innovation is at the root of productivity improvements. 相似文献
We study the efficiency property of responsive pricing, a scheme that proposes to increase prices as a function of the level
of capacity utilization in environments where traditional allocation schemes (e.g. competitive markets, non-linear pricing)
cannot be implemented in practice. We show that although responsive pricing implements allocations that are arbitrarily close
to full capacity utilization (no wasted capacity and no excess demand), these allocations are not always efficient. We identify
conditions under which efficiency occurs and discuss implications for the use of responsive pricing.

This paper studies precautionary saving when many small risks are considered. We first introduce two simultaneous risks: labor income and interest rate risks. We show that, in this context, sufficient conditions for precautionary saving are weaker than in similar models. Moreover, we find that, unlike previous literature, precautionary saving can occur in the case of negative covariance between the two risks and in the case of imprudence. We then extend our analysis to a three-risk framework, where a background risk is included. We derive sufficient conditions for precautionary saving which are interpreted in the light of the previous literature. 相似文献
This article advances the theoretical and instrumental understanding of corporate heritage identities. This exploratory, empirical study focuses on both the nature and the relevance of corporate heritage identity as employed by managers for corporate identity management purposes. The research is undertaken within Britain's oldest brewery – one of the oldest corporate entities in Great Britain with a provenance spanning many centuries – and utilizes a qualitative and theory building case study. The research reveals two classes of management responsibilities vis-à-vis corporate heritage identity management, namely corporate heritage management activities and corporate heritage implementation strategies, which follow a particular corporate heritage identity implementation pattern identified. A normative framework synthesizes and marshals the findings. The empirical study provides insight into corporate heritage identity management and is potentially useful to both scholars and practitioners. This study advances the nascent area of corporate heritage identity management by providing empirical and theoretical insight into the salience and strategic relevance of corporate heritage identity as a resource for corporate marketing. The article provides a normative framework of actionable categories of activities related to the management and implementation of substantive corporate heritage identity dimensions. 相似文献
Using information from the Peruvian administrative consumer system from 1998 to 2010, the paper assesses hypotheses taken from selection theory in the context of legal disputes (Priest and Klein, The Journal of Legal Studies 13(1):1, 1984) and political science. Hypotheses from selection theory regarding the influence of plaintiff stakes, informational asymmetry and, to a lesser extent, litigation costs on both selection decisions and trial outcomes were confirmed. In addition, the results corroborate other implications of selection theory, such as the non-random nature of selection processes. However, no evidence has been found regarding the theory’s prediction that the share of plaintiff victories at trial will converge to 50%. The results also show that in the Peruvian consumer protection system, plaintiffs win more often than do defendants, suggesting the pre-eminence of pro-consumer trial standards over other factors. Moreover, the evidence confirms the hypotheses taken from “party capability theory” (Galanter, Law & Society Review 9(1):95–160, 1974) regarding the influence of litigant characteristics on consumer protection legal outcomes. Finally, the results also demonstrate the relevance of ideological and attitudinal factors as determinants of consumer administrative trial decisions. 相似文献
This paper is a theory‐based study of the long‐run determinants of the current account (CA). For many OECD economies after the Second World War, there has been more long‐run variation in the CA data than is emphasised by a ‘Permanent Income’ version of the intertemporal approach that is based on consumption‐smoothing and that allows only transitory CA imbalances. A theoretical model of the CA is developed, based on the ‘broader’ variant of the intertemporal approach that stresses the long‐term component of the CA. We find that some key theoretical predictions hold, while others fail, validating the approach but also pointing to its limitations. 相似文献
The current study examines the antecedents of youth financial behavior. By grounding the conceptual framework on empowerment theory, we argue that in addition to financial knowledge other elements such as intrapersonal (e.g., locus of control and motivation) and interactional elements (e.g., parental financial teaching and behavior) also impact youth financial behavior. To test the hypotheses, structural equation modeling is used on a data set of youth from Western Canada. The results indicate that external locus of control has the highest total effect on youth financial behavior followed by parental influence and motivation. Findings are validated by performing several robustness checks and multigroup analysis. Organizations trying to influence youth financial behavior should broaden the understanding of empowerment to include personal worldview, motivation, as well as social surroundings. 相似文献
We introduce a general framework for Markov decision problems under model uncertainty in a discrete-time infinite horizon setting. By providing a dynamic programming principle, we obtain a local-to-global paradigm, namely solving a local, that is, a one time-step robust optimization problem leads to an optimizer of the global (i.e., infinite time-steps) robust stochastic optimal control problem, as well as to a corresponding worst-case measure. Moreover, we apply this framework to portfolio optimization involving data of the . We present two different types of ambiguity sets; one is fully data-driven given by a Wasserstein-ball around the empirical measure, the second one is described by a parametric set of multivariate normal distributions, where the corresponding uncertainty sets of the parameters are estimated from the data. It turns out that in scenarios where the market is volatile or bearish, the optimal portfolio strategies from the corresponding robust optimization problem outperforms the ones without model uncertainty, showcasing the importance of taking model uncertainty into account. 相似文献
We examine a problem of demand for insurance indemnification, when the insured is sensitive to ambiguity and behaves according to the maxmin expected utility model of Gilboa and Schmeidler (J. Math. Econ. 18:141–153, 1989), whereas the insurer is a (risk-averse or risk-neutral) expected-utility maximiser. We characterise optimal indemnity functions both with and without the customary ex ante no-sabotage requirement on feasible indemnities, and for both concave and linear utility functions for the two agents. This allows us to provide a unifying framework in which we examine the effects of the no-sabotage condition, of marginal utility of wealth, of belief heterogeneity, as well as of ambiguity (multiplicity of priors) on the structure of optimal indemnity functions. In particular, we show how a singularity in beliefs leads to an optimal indemnity function that involves full insurance on an event to which the insurer assigns zero probability, while the decision maker assigns a positive probability. We examine several illustrative examples, and we provide numerical studies for the case of a Wasserstein and a Rényi ambiguity set.
