This paper investigates the role of non-technological innovation on firms' innovation propensity and performance. We note that emphasis on technological innovation alone is misleading, as a firm's decision to undertake technological innovation brings about a more complex and general process which may involve new attitudes regarding organization and market orientation. We analyse the relationship between product and marketing innovation in manufacturing, focusing specifically on the food industry. We propose a bivariate probit model in which product and marketing innovation are estimated taking into account their reciprocal interactions. This enables us to provide more efficient and realistic estimates of a firm's probability of introducing either a new or improved product or a new marketing technique. In addition, the proposed model provides the determinants of such probabilities.  相似文献

The literature on antidumping (AD) has documented various aspects of this protectionist tool. However, a peculiar feature of AD has not received much attention: these measures are endogenous to the behaviour of the exporting firms, which can adjust the dumping margin by changing their export price and ask the authority to amend the AD measures accordingly. The objective of this paper is to fill part of this gap in the literature by analysing the AD reviews conducted by the European Union for affirmative petitions initiated in 1980–2009. To this end, a novel data set of all such reviews has been assembled. Summary statistics reveal that more than a third of all petitions concluded with the imposition of AD measures are reviewed at least once before their expiration, and most reviews lead to lower AD duties (although, almost 20 per cent of the firms investigated through interim reviews see their duties increase). There are significant differences in the outcome of the reviews depending on the party requesting them (i.e. reviews lodged by European producers are less likely to lead to lower duties). These conclusions are confirmed by the econometric analysis, which also shows that Chinese firms see their duties reduced significantly less than those of firms from other countries.  相似文献

This paper tests for structural stability of the Solow growth model, as recently extended to human capital and applied to a large section of countries by Mankiw, Romer and Weil. The evidence is obtained by ranking each explanatory variable of the model in ascending order and then running recursive regressions and by then splitting the original sample according to cluster analysis before running separate regressions. The evidence shows that the model exhibits overall structural breaks; the convergence coefficient, however, is very stable; the coefficients of the production factors become unstable where the factors become very abundant or very scarce; the coefficient of labour growth is negative and significant, as required by the theory, only if a small group of countries with scarce labour is considered; the same coefficient is instead positive and significant for a group of countries with abundant labour and favourable initial income and investments; the coefficient of investment in human capital is not significant if abundant labour countries or, simply, if influential countries in the regression are not considered.  相似文献

The reform of water pricing policies may represent an effective instrument for enhancing the efficient use of water resource. However, policy makers fear that a change in the pricing methods may cause income loss for some farmers, and that this income inequality may generate public discontent and policy inertia. The aim of this paper was to compare some pricing methods in order to measure their effects on income distribution. The analysis focuses on the income distribution among different types of farms, and the income distribution between different social groups (landowners, capitalists and workers) in the short term. A linear programing model based on expected utility theory is used to take into account the effect of commodity prices and rainfall variability, which are among the most relevant factors affecting farmers’ income. According to the findings, water pricing schemes do not affect the income distribution among farm types, although a significant impact emerges on the distribution among social groups, and in particular on the wages of temporary workers.  相似文献

In high-frequency financial data not only returns, but also waiting times between consecutive trades are random variables. Therefore, it is possible to apply continuous-time random walks (CTRWs) as phenomenological models of the high-frequency price dynamics. An empirical analysis performed on the 30 DJIA stocks shows that the waiting-time survival probability for high-frequency data is non-exponential. This fact imposes constraints on agent-based models of financial markets.  相似文献

The greenhouse effect forces national Governments to design environmental tax policies for facing not only global warming but also the negative economic consequences resulting from the reduction of emissions such as a negative change of GDP. This paper aims at verifying the impact of an environmental fiscal reform able to attain both the reduction of greenhouse gas emissions and the regional double dividend. We have decided to follow the computable general equilibrium approach for modelling the multisectoral income circular flow in the case of a bi-regional economy as described by a Social Accounting Matrix we have built for this purpose. The tools of analysis we chose represent suitable and consistent instruments in order to quantify the effects of an environmental tax reform. They can in fact highlight the possible differences in responses between macro regions in terms of regional GDP changes, regional prices and regional employment rate. In fact, the extended multi-sectoral framework, on which the model is developed, represents economic activities, imperfect labour market and institutional sectors behaviours in each macro region. The simulations performed concern the introduction of a progressive and proportional green tax on each type of commodity according to the corresponding level of CO2 emissions. Furthermore all simulations introduce a recycling scheme of green tax revenues, whose aim is reducing both the income tax and the regional tax on activities (IRAP). The application is done on a bi-regional Social Accounting Matrix for Italy for the year 2003.  相似文献

The aim of this study is to provide new theoretical insights and empirical evidence on the effect of market and technological uncertainty on the market valuation of a firm's R&D capital. A set of hypotheses is developed adopting a real options logic and tested on a panel dataset of 290 manufacturing firms traded in the UK. Consistently with our theoretical model, we show that market and technological uncertainty have distinct effects on the valuation of R&D investments. The results have several important implications for resource allocation to R&D under uncertainty, which we discuss in the concluding section. Copyright © 2008 John Wiley & Sons, Ltd.  相似文献

We explore sensory experiences and expectations of Italian and German organic consumers when purchasing and eating organic food. Ten focus group interviews were performed and the results were analyzed using qualitative content analysis. Outcomes indicated that although sensory attributes are not the main purchase drivers, flavor and odor are the most important in driving consumers' choice. Findings also suggested that training consumers' sensory abilities offers new market opportunities to organic marketers. From a marketing perspective, Italian consumers seem to equally appreciate nonsubjective as well as subjective marketing information about organic products, whereas in Germany non subjective aspects appear to be predominant.  相似文献

Abstract. In the United States many antidumping petitions are withdrawn before the investigations are completed. Prusa (1992) argues that petitions are used by domestic industries to induce foreign industries into collusive agreements. In his model, all antidumping petitions should be withdrawn, which is not the case. This paper provides a model in which only some petitions are withdrawn. Withdrawal depends on two key parameters: coordination cost and bargaining power of domestic and foreign industries. A new data set is constructed to test the model on the U.S. experience for the period 1980–97. The econometric analysis supports the theoretical conclusions of the model.
