This study aims to analyze the relationships between entrepreneurship, innovation and economic growth, and to show the feedback effects in these relationships. A Schumpeterian approach considering three equations linking GDP, innovation, and entrepreneurship facilitates this analysis. This paper presents empirical analysis of entrepreneurial activity in 13 developed countries. Panel data with fixed effects methodology, for the period 2002 to 2007, provides the means to estimate the equations. The analysis shows that several factors have positive impacts on innovation and entrepreneurship, including monetary policy and social climate. Additionally, a feedback effect is at work: economic activity promotes entrepreneurship and innovation activities, and the latter enhances economic activity. Therefore, policymakers must consider this effect when designing economic policies.  相似文献

Our paper assesses the impacts of the 1996 US Farm Bill on production decisions. We apply the expected utility model to analyze farmers’ behavior under risk and assess how farmers’ production decisions change in the presence of government programs. Specifically, we empirically evaluate the relative price and the risk-related effects of farm policy changes at the intensive margin of production, as well as the extra value that these policies add to farmers’ certainty equivalent. We use farm-level data collected in Kansas to estimate the model. We find evidence that decoupled government programs have only negligible impacts on production decisions.  相似文献

The present paper addresses the dynamics of innovation, by extending the analysis beyond a static-economic perspective. It offers a dynamic-institutional mapping of relational capacities to dynamically innovate. Its main goal is to contribute to the above-mentioned research theme by presenting a new methodology able to pinpoint different trends in the relational capacities of institutions when they are innovative. Thereby, major characteristics in the networks of innovation are identified. This investigation uses an extended set of private institutions and public organizations located in Portugal, evaluated by their WebPage contents. To this data set a new combination of multivariate statistical methods is applied to detect group performances, to compare them, and to identify gradients of capacity to dynamically innovate. The results demonstrate that this method can provide extremely useful and tailor-made information for policy evaluation at regional or national levels.  相似文献

We propose tests of the two assumptions under which anchoring vignettes identify heterogeneity in reporting of categorical evaluations. Systematic variation in the perceived difference between any two vignette states is sufficient to reject vignette equivalence. Response consistency - the respondent uses the same response scale to evaluate the vignette and herself - is testable given sufficiently comprehensive objective indicators that independently identify response scales. Both assumptions are rejected for reporting of cognitive and physical functioning in a sample of older English individuals, although a weaker test resting on less stringent assumptions does not reject response consistency for cognition.  相似文献

Our article assesses the impacts regarding on-farm investment and production decisions resulting from the Partially Decoupled (PD) payment scheme implemented during the 1990s and first half of the 2000s within the framework of the Common Agricultural Policy (CAP). The Spanish Cereal, Oilseed and Protein (COP) sector is taken as a case study regarding this effect due to its economic and political relevance in Spain. The empirical analysis is applied to farm-level data from 2000 to 2004 using the Farm Accountancy Data Network (FADN). We use a reduced-form application of the dual model of investment under uncertainty and estimate a system of censored and uncensored equations. PD payments are found to increase short-run production and generate a statically significant increase in the investment in farm assets. Results also show the importance of assessing the effects of PD payments in a dynamic framework as applied in this article.  相似文献

The aim of this paper is to provide a better understanding of the effect of social networks on innovation through the analysis of territorial systems of firms. Although industrial districts enjoy a number of advantages, they also present some relevant limitations. We have labelled the difficulties that have been identified as the exploring concern. However, periphery actors, such as supporting organisations, playing the role of intermediary agents allow districts to escape from exploring restrictions, since they can monitor what is happening outside the district and, in consequence, the involvement of supporting organisations has a positive effect on innovation. The study reported in this paper is based on a sample of 154 manufacturing firms that belong to industrial districts in the Valencia Region (Spain). Findings support the positive association between local institution involvement and innovation of companies.  相似文献

This paper examines the effects of macro-environmental variables on country-level patterns of participation by firms on the US NASDAQ stock exchange. NASDAQ’s popularity can be linked to the strength of its technological system, as well as the high frequency of listings of technology-oriented firms. Using concepts from organization theory, strategy and international business, we consider the impact of political, legal, cultural, and colonial heritage status on the strategic capital-seeking behavior of non-US companies in US markets. We empirically demonstrate that similarity in legal systems and a shared colonial heritage will influence the probability of a non-US country having firm participation on the NASDAQ. The results also indicate that the effects of institutional forces are not static processes  相似文献
