In a dynamic model with a keeping‐up‐with‐the Joneses preference and market imperfections, we attempt to investigate under what circumstances and for what reason the optimal tax should be state‐varying. We extend the Ljungqvist and Uhlig (2000) proposition to include preferences that exhibit non‐homotheticity. We show that a keeping‐up‐with‐the‐Joneses preference (a non‐intertemporally‐dependent preference) can lead the social planner to commit to a state‐contingent tax on labor income. Moreover, the optimal labor income tax can be either procyclical or countercyclical with respect to economic fluctuations, this crucially depending on whether the level of contemporaneous consumption increases or decreases the wedge between the intertemporal substitution elasticity of households and of the social planner. 相似文献

In this paper, we extend the standard model of private provision of public goods by including consumption externalities to characterize a situation in which economic activities pollute the environment. We consider a case in which there are an industrial country which can afford to invest in the environment and a developing country which cannot. Then, we show that international income transfers in both directions can improve the global environmental quality as well as the welfare of each country. We also show that the results have important implications for policies such as official development assistance or the assignment of tradable emission permits. 相似文献

The Environmental Protection Agency is currently gathering data to regulate livestock facilities under the Clean Air Act, legislation that purports to protect public health. To set rational policy, estimates of health externalities associated with livestock farming are necessary. This study uses geographic shifts in the industry to measure the impact of pollution on infant health. The article finds that a doubling of production leads to a 7.4% increase in infant mortality. This finding is robust with respect to the inclusion of multiple fixed and time-varying controls. The mortality increases are driven by elevated levels of respiratory diseases, providing suggestive evidence of an air pollution mechanism. 相似文献

Using an overlapping generations model in which human capital accumulation has positive external effects on the production
of the human capital of future generations, this paper analyzes implications of agents’ having preferences for educational
status, represented by human capital holdings relative to the social average. Examining the value and sign of the optimal
distortionary tax in the optimal taxation scheme, we analyze the efficiency of the level of human capital accumulation in
a decentralized economy. The desire for educational status can compensate for insufficient accumulation of human capital stemming
from human capital externalities directed toward future generations. 相似文献

Summary. The paper studies a model of accumulation and growth where a continuum of heterogeneous firms play dynamically optimal strategies along a (rational expectations) equilibrium. The key feature of the model is that
firms' technological decisions are assumed subject to both friction and external effects. This gives rise to a wide multiplicity of equilibrium behavior, any path of sustained growth requiring that the
economy tackle a never-ending chain of fresh coordination problems. This setup is modelled as a (non-atomic) dynamic game,
suitable conditions being provided that partially characterize when sustained growth is a possible (never the unique) equilibrium
outcome.

Two highly influential articlesin the literature on green taxes and double dividends are Bovenbergand de Mooij (1994) and Goulder (1995). Goulder's primary concernis whether or not green tax reforms may increase welfare definedexclusive of environmental quality, while Bovenberg and de Mooijprimarily focus on the employment effects of such reforms. Unfortunately,Goulder misinterprets Bovenberg and de Mooij's results in takingthe sign of the uncompensated wage elasticity of labour supplyas being the decisive factor for whether or not welfare exclusiveof environmental quality rises under a green tax reform. Thiserror is pointed out and corrected in this note. 相似文献

In network industry under Cournot and Bertrand competition, we examine a model when owners of firms hire biased managers who have incorrect market demand. Contrast to previous studies, we show that (i) regardless of the strength of network externalities when consumers form the responsive and passive expectations, owners realize strategic advantage by hiring biased managers to be more aggressive under Cournot and Bertrand competition, (ii) firms prefer facing passive expectations for the weak network externalities and vice versa for the strong network exteranlities under Bertrand and Cournot competition, (iii) if the network size is sufficiently large, then the prisoner's dilemma that firms hire aggressive managers no longer exists under both competition modes. As with no delegation case, we obtain the different rankings of firms' profit depending on both network externalities and forming of expectations under Cournot and Bertrand competition. 相似文献

现行土地流转决策的依据就是土地使用价值的简单比较,导致农地流失严重。因农地向城市的流转具有不确定性与不可逆性,本文在对农地的选择价值与外部性分析的基础上,构建出具有科学性与前瞻性的理论决策模型。 相似文献

Using data on US manufacturing, I estimate internal returns to scale and external effects for the consumption and investment sectors. I construct panels of data at the industry level and use results of gross output production function estimation to derive implied estimates in a value added specification. For the investment sector, returns to scale appear to be slightly increasing, with evidence of a positive external effect. For consumption, the evidence indicates decreasing to constant returns to scale. I discuss the implications of these results for the empirical plausibility of indeterminacy in recent multi-sector models of the business cycle. 相似文献
