In this article we investigate the changes in corporate investment dynamics in the aftermath of the global financial crisis. Using firm-level data from six Latin American countries from 2002 to 2015, we show that firms are less constrained and have greater ability to invest after the crisis. However, the willingness of firms to invest optimally is reduced. This is supported by strong evidence that during the postcrisis period investment–cash flow sensitivity disappears, investment-q sensitivity increases, and the estimated speeds of adjustment for target investment decrease. Moreover, after the crisis, firms notably increase their efforts to attain optimal cash and leverage levels. Our analysis implies that firms may not always be willing to invest optimally. The willingness to invest optimally appears to be time variant and moves together with the dynamics of cash and leverage policies, albeit in opposite directions. 相似文献

Bio-economic modelling has become a useful tool for anticipating the outcomes of policies and technologies before their implementation. Advances in mathematical programming have made it possible to build more comprehensive models. In an overview of recent studies about bio-economic models applied to land-use problems in agriculture and forestry, we evaluated how aspects such as uncertainty, multiple objective functions, system dynamics and time have been incorporated into models. We found that single objective models were more frequently applied at the farm level, while multiple objective modelling has been applied to meet concerns at the landscape level. Among the objectives, social aspects are seldom represented in all models, when being compared to economic and environmental aspects. The integration of uncertainty is occasionally a topic, while stochastic approaches are more frequently applied than non-stochastic robust methods. Most multiple-objective models do not integrate uncertainty or sequential decision making. Static approaches continue to be more recurrent than truly dynamic models. Even though integrating multiple aspects may enhance our understanding of a system; it involves a tradeoff between complexity and robustness of the results obtained. Land-use models have to address this balance between complexity and robustness in order to evolve towards robust multiple-objective spatial optimization as a prerequisite to achieve sustainability goals. 相似文献

Cognition,Social Impulse,and the Principle of Adaptation: Insights into the Peirce-Veblen Connection
Manuel Ramon Souza Luz 《Journal of economic issues》2019,53(2):349-354
This article seeks to offer insights into the connections between Charles S. Peirce and Thorstein B. Veblen regarding their understanding of the logic of scientific thought and cognition. In this sense, this work explores how both Veblen and Peirce dismissed the Cartesian notion of unmediated cognition and how they sought to depict cognition as a process. Furthermore, this article presents Peirce’s concept of “social impulse” and Veblen’s “principle of adaptation” as complementary perspectives on science and cognition that have strong evolutionary content. 相似文献

Our inquiry advances a comparison of the anthropological content of Thorstein Veblen’s evolutionary perspective with the foundations of the political anthropology drawn from selected works of Pierre Clastres. We seek to establish that what can be referred to as a clastrean reference can simultaneously offer new perspectives on institutionalism, while maintaining a radical and emancipatory understanding of Veblen’s writings. In this sense, we seek to reconsider and reevaluate the role of economic surplus drawn from Veblen’s anthropology, while also offering a general and critical perspective for understanding the emergence of coercive power within societies. 相似文献

We consider a consumption and investment problem where the market presents different regimes. An investor taking decisions continuously in time selects a consumption–investment policy to maximize his expected total discounted utility of consumption. The market coefficients and the investor's utility of consumption are dependent on the regime of the financial market, which is modeled by an observable finite-state continuous-time Markov chain. We obtain explicit optimal consumption and investment policies for specific HARA utility functions. We show that the optimal policy depends on the regime. We also make an economic analysis of the solutions, and show that for every investor the optimal proportion to allocate in the risky asset is greater in a "bull market" than in a "bear market." This behavior is not affected by the investor's risk preferences. On the other hand, the optimal consumption to wealth ratio depends not only on the regime, but also on the investor's risk tolerance: high risk-averse investors will consume relatively more in a "bull market" than in a "bear market," and the opposite is true for low risk-averse investors. 相似文献

This study aimed to explore how young adults in Puerto Rico perceive and respond to corporate social responsibility (CSR) initiatives in comparison with young adults in the United States. It explored the awareness of CSR, the importance placed on four CSR dimensions (economic, legal, ethical, philanthropic), and how such perceptions potentially link to individuals' behavioral intentions. An online survey found that Puerto Rican respondents perceive themselves as having a higher level of awareness of CSR than young adults in the United States; however, the level of CSR awareness among these demographic groups was low in both countries. Puerto Rican respondents placed more importance on the economic dimension of CSR, while U.S. respondents placed more importance on the legal dimension of CSR. CSR awareness was positively linked to behavioral intentions only among U.S. respondents. The allocated importance of CSR was a critical factor for respondents in Puerto Rico to show more favorable behavioral intentions. 相似文献

Optimal capital taxes may be positive in the steady state in Ramsey models with an incomplete set of factor taxes. I show this possibility crucially depends on how fiscal policy is constrained at date t = 0. If the government is barred from manipulating the value of initial assets, the Chamley–Judd result reappears: the optimal capital tax is always zero in the steady state. 相似文献

Science and Technology Parks (STP) have attracted considerable attention and public funds in recent years. However, the conclusions on their effectiveness remain mixed. This work evaluates the impact of STP on firm product innovation in the Spanish context, as an example of a less developed innovation system in which regional and national governments are prioritizing STP initiatives. This work draws on a large sample of firms provided by the Spanish Survey on Technological Innovation that is conducted annually by the National Statistical Institute. We explore alternative econometric methods to obtain average treatment effects for firms located in 22 Spanish STPs. Our results show that Spanish STPs have a strong and positive impact on the probability and amount of product innovation achieved by STP located firms. These results hold when the endogeneity of STP location is taken into account. 相似文献

Corporate diversification is one of the broadest investigation topics in strategic management, but there are important gaps in the literature regarding entry mode choice. Few studies have examined the extent to which pre-entry conditions influence the choice of entry mode into new businesses. Past research has focused exclusively on internal development and acquisition as ways of entering new businesses, without considering the existence of hybrid forms, such as strategic alliances, that have experienced extensive growth during the last decade. Here we present an in-depth analysis of entry mode choice that uses an integrative perspective of corporate diversification and considers strategic alliances as an alternative to traditional approaches. A survey of 272 domestic diversifying entries by 155 Spanish firms allows us to characterize the use of cooperative agreements in diversification and to stress the role of inter-firm cooperation in acquiring the knowledge and capability required to grow into new businesses. 相似文献

Learner-centred approaches follow the prevailing tendency in modern University reforms which are primarily concerned about
“how people learn”. The methodologies can be learner-centred in the sense of placing the student as the main actor of the
teaching–learning process by increasing his interactivity and participation, but also considering what is relevant for the
student by measuring the learner satisfaction. In order to promote both aspects, this paper proposes a synchronous software-based
active methodology that makes use of the simulations to show a virtual scenario to the students and challenge them to predict
and discuss the evolution of the scenario. The proposed methodology improves the visual interface, promotes discussion both
among students and with the teacher in a brainstorming stage and shows real-world examples. This software-based methodology
has been implemented into an Electric Machinery course at the University of Seville (Spain), and the evaluation has been carried
out considering both the affective and cognitive domains. Principal components analysis proves to be useful to highlight the
dimensions with a higher influence on learner satisfaction and the affective and cognitive results confirm the successful
implementation of the proposal. 相似文献
