从制造业的角度出发,分析了政府对环境管制(ER)的两种形式:正式管制(FER)和非正式管制(I-ER),建立了环境管制均衡方程,并且采用面板数据的分析方法对理论假设进行了验证。研究表明,假设的影响制造业环境管制的主要因素:政府保护意愿、劳动密集程度、产业规模、经济外向度、产业国有化程度、科技吸收转化支出和劳动力素质的高低均产生了显著的影响。 相似文献

The present research proposes a new generalisation of the logistic model aiming at technology diffusion forecasting. Regarding criticisms and failures reported in the literature to apply logistic function for long-term forecasting, in our work we focused on short-term accuracy of forecast. To formulate the model, based on mathematical approximation, at first the differential equation governing the diffusion process is found and then by solving the derived differential equation, the forecast function is obtained. In all steps, mathematical tools from numerical analysis are used. We compared the New Generalized Logistic Model with eight of the most renowned models in the literature. The model led to more accurate fits and forecasts than those obtained from other models we applied for comparison. 相似文献

Although the number of regional trade arrangements (RTAs) among the lowest-income developing countries is surging, the literature on their welfare effects is still scarce, and the few that exist fail to provide conclusive results. Furthermore, these RTAs are dominated by countries with a small share of total exports destined for intraregional trade flows. Our study focuses on the welfare effects of RTAs (pertaining to trade creation and trade diversion) among this group of countries. We use a theoretically justified gravity model to estimate welfare effects, focusing on trade creation and trade diversion and deviating from the norm in related studies, accounting for heterogeneity in third countries. Using ECOWAS as a sample, we estimate welfare effects on 1992–2012 annual bilateral imports for 14 countries from 169 countries. Contrary to conventional expectations in the literature, we find that economic integration among small and relatively low-income countries that have a small share of total trade with each other is welfare-improving for the members as a group, for the majority of the individual member countries, and for some third countries. Accounting for heterogeneity in third countries reveals that an RTA among low-income countries has a particularly robust trade-creation effect. 相似文献

Theories of multinational enterprises emphasize that foreign direct investment (FDI) is undertaken in different industries for different reasons, yet studies of the effects of rights and governance on FDI generally rely on aggregate-level FDI data. This paper evaluates US FDI outflows to 15 industries (eight manufacturing, seven non-manufacturing) in 54 countries in a linear dynamic panel data gravity FDI model using a ‘system’ generalized method of moments estimator and several widely used rights and governance indexes. At the aggregate level, we estimate that stronger rights and governance have a positive effect on FDI, consistent with most prior studies. At the industry level, we estimate larger positive effects of rights and governance on FDI for service than manufacturing industries, particularly for the information and the finance and insurance industries. 相似文献

The proper panel econometric specification of the gravity equation: A three-way model with bilateral interaction effects 总被引:6,自引:0,他引:6
We argue that the proper specification of a panel gravity model should include main (exporter, importer, and time) as well
as time invariant exporter-by-importer (bilateral) interaction effects. In a panel of 11 APEC countries, the latter are highly
significant and account for the largest part of variation.

Family influences on economic performance are investigated. In particular, sibship sex composition is related to hourly wages using data from the National Longitudinal Survey of Youth 1979. The wages of men are increasing in the proportion of siblings who are brothers, but the wages of women are insensitive to sibling gender. Nonwage outcomes are generally unaffected. Contrasts by age structure and demographic group are also presented. The analysis addresses econometric challenges like the endogeneity of fertility and selection into the workforce. In addition, mechanisms such as labour market interactions, human capital investment and role model effects are documented. A questionnaire on job search indicates a same-gender bias in the use of brothers and sisters in obtaining employment. Developmental and psychological assessments suggest that brothers may be associated with worse childhood home environments and more traditional family attitudes among women. The findings are policy relevant and contribute to an understanding of gender differences and earnings inequality. 相似文献

This paper investigates the relationship between the practices put in place by firms to search for local and distant knowledge, ambidexterity and firms’ performances; attention is then focused on analysing the antecedents and consequences of ambidexterity in the search phase of the innovation process. Structural equation modelling has been used in order to test these hypotheses in a sample of Italian high-tech companies. Results of the study show a positive impact of the practices used by firm to search for distant knowledge on both ambidexterity and firms’ performances as well. Implications of these results are discussed in the paper. 相似文献

We examine whether Italian household consumption exhibits excess sensitivity to “severance pay”, a sizable lump-sum that workers receive at job termination. We find no evidence of excess sensitivity of non-durable expenditure to this anticipated cash-in-hand change. 相似文献

We examine the effect of simultaneous price changes on the total demand for a group of goods, which we call a compound commodity. Specifically, we consider unit and proportional cost components (e.g., taxes, transportation costs) imposed on compound commodities. If the unit cost is positive, then the proportional cost raises the relative price of the more expensive good, and thus induces substitution towards the less expensive good within this group. Then, the substitution effect of the proportional cost for a compound commodity is non‐negative if and only if the compound commodity and the other goods are, on average, not strongly substitutable. 相似文献
