We consider a representative agent, infinite-horizon economy where production requires private and public capital. The supply of public capital is financed through distortionary taxation. The optimal (second best) tax policy of a benevolent government is time inconsistent. We therefore introduce explicitly the constraint that at no point in time the revision of the original tax plan is desirable. We completely characterize the (third best) tax plan that satisfies this constraint, and estimate the difference in tax rate between the second and third best policy for a wide range of parameters. For some of these the difference between the second and third best tax rates is large, and so are the associated rates of economic growth. 相似文献

In this paper we analyse the potential asymmetric response of retail prices for gasoline and diesel‐fuel to changes in oil prices for the Spanish economy and its relation with the so‐called ‘rockets and feathers’ behaviour. We show that the assumption made by previous studies, which use as the key explanatory variable the sign –positive or negative‐ of the change in international oil prices, is inadequate for the Spanish case and the magnitude of the change in international oil prices is also relevant. For small changes in international oil prices there is neither price asymmetry nor rockets and feathers behavior in the retail markets. However, price asymmetries in line with rockets and feathers behavior in retail gasoline and gasoil markets are present when these changes exceed a certain threshold. Following Martín‐Moreno et al. (2018) we first apply an Auto‐regressive Error Correction Model and endogenously estimate the threshold triggering the rockets and feathers behaviour. A time‐varying nature for the dynamic response of retail prices to oil price shocks is revealed when we estimate the TAR‐ECM model using rolling windows. Hence, in a second stage, we use a Markov‐switching estimation of the model to test the robustness of the results given its suitability to changing environments. This study could have relevant policy implications for the Spanish gasoline and gasoil retail markets due to the ongoing debate on the existence of a rockets and feathers behavior in gasoline and gasoil retail markets between the Spanish regulatory body and the oil companies. 相似文献

We examine the effect of financial constraints on firm investment and cash flow. We combine data from the Spanish Mercantile Registry and the Bank of Spain Credit Registry to classify firms according to whether they are family‐owned, not family‐owned, or belong to a family‐linked network of firms and according to their number of banking relations (with none, one, or several banks). Our empirical strategy is structural, based on a dynamic model solved numerically to generate the joint distribution of firm capital (size), investment, and cash flow, both in cross sections and in panel data. We consider three alternative financial settings: saving only, borrowing and lending, and moral hazard constrained state‐contingent credit. We estimate each setting via maximum likelihood and compare across these financial regimes. Based on the estimated financial regime, we show that family firms, especially those belonging to networks based on ownership, are associated with a more flexible market or contract environment and are less financially constrained than nonfamily firms. This result survives stratifications of family and nonfamily firms by bank status, region, industry, and time period. Family firms are better able to allocate funds and smooth investment across states of the world and over time, arguably done informally or using the cash flow generated at the level of the network. We also validate our structural approach by demonstrating that it performs well in traditional categories, by stratifying firms by size and age, and find that smaller and younger firms are more constrained than larger and older firms. 相似文献

西部地区禀赋比较优势与制成品产业结构优化 总被引:1,自引:0,他引:1
在中国入世和西部开发的背景下,西部地区面临着全面开放和要素禀赋结构不断变化的环境。西部原先的产业结构及计划经济体制下的隐性失业逐渐暴露,并且缺乏经济发展及结构优化所必须的资金。这要求地方政府的相关政策要有很强的务实性。西部地区的制成品产业结构优化应建立在当地客观的要素禀赋结构基础之上,动态比较优势的实现要依赖于禀赋结构的有效升级。因此,民间资金与外资的积极参与在很大程度上有赖于西部市场化进程的加快和禀赋比较优势的充分体现。 相似文献

This paper compares the performance of a log-linear method and a parameterized expectations method in solving a dynamic general
equilibrium endogenous growth model with human capital. Quantitative evaluation based on second moment statistics shows that
the results provided by the two numerical methods are very similar in this framework whenever the propagation mechanism of
technology shocks is weak. However, the cross correlations of some relevant variables in the RBC literature obtained from
the two methods are significantly different when the model exhibits a strong propagation mechanism. The parameterized expectations
method captures the sensitiviness of second moment statistics to the curvature of the utility function while the log-linear
method does not. 相似文献

Climate change and its marginalizing effect on agriculture 总被引:1,自引:0,他引:1
The agriculture of some areas considered marginal in the EU agricultural context is being questioned due to its low productivity and growing dependence on economic aid programs Common Agricultural Policy (CAP). This study shows that climate change increases these areas marginalisation of since worsens crop growth conditions. The influence of climate change on the agricultural sector is analyzed using the Multicriteria Decision Paradigm with information provided by the Erosion-Productivity Impact Calculator (EPIC) and a General Circulation Model (GCM) as inputs for multicriteria mathematical programming models. The results obtained show climate change effects on the crop portfolio. Further results suggest that climate change effects are not only economics and environmental, reducing the suitable area for crops, but also social as it causes loss of jobs in the agricultural sector. 相似文献

This article presents new econometric evidence on the comparative behavior of worker cooperatives and capitalist firms, highlighting the differences in wages and employment responses. We use a comprehensive panel data set that covers the entire population of cooperatives and their capitalist counterparts registered in the social security records in Uruguay from April 1996 to December 2005. We analyze the data to study the employment and wage decisions in both types of enterprises, the results of which suggests that their adjustment mechanisms to idiosyncratic price changes and macroeconomic shocks may differ greatly. The data set also allows us to estimate wage and employment variations for members and non-members of cooperatives separately, and provides an empirical test for the so-called degeneration hypothesis. Our findings are broadly consistent with previous studies for Italian cooperatives and plywood cooperatives in the United States. As studies of this kind are so few, our research provides a significant contribution to the empirical literature on labor managed firms. Moreover, comparing worker cooperatives and capitalist firms offers an exceptional opportunity to determine how control by workers may lead to different organizational behavior. 相似文献

Over a five-year period in the 1990s Vietnam experienced annual economic growth of more than 8% and a 15 point decrease in the proportion of children chronically malnourished (stunted). We estimate the extent to which changes in the distribution of child nutritional status can be explained by changes in the level and distribution of income, and of other covariates. This is done using data from the 1993 and 1998 Vietnam Living Standards Surveys and a flexible decomposition technique based on quantile regression that explains change throughout the complete distribution of child height. One-half of the decrease in the proportion of children stunted is explained by changes in the distributions of covariates and 35% is explained by change in the distribution of income. Covariates, including income, explain less of the decrease in very severe malnutrition, which is largely attributable to change in the conditional distribution of child height. 相似文献
