Capital income taxation,depreciation allowances and economic growth: A perfect-foresight general equilibrium model

Conclusions The results indicated in Table 1 show that incomplete depreciation allowances reinforce the distortions in the equilibrium growth path brought about by an ideal capital income tax. A reduction in the deductible share of economic depreciation, like an increase in the tax rate, raises the current level of consumption, but reduces the steady state levels of consumption and capital per efficiency unit of labour.The reason for these distortions is that the tax law is able to drive wedges both between the rate of time preference and the market rate of interest, and between the latter and the marginal productivity of capital. The first wedge is created through capital income taxation as such and its size is directly related to the tax rate. The second wedge is created by the incomplete deductibility of depreciation. Its size is directly related to the tax rate and inversely to the deductible share of depreciation. For the distortion in the growth path of the economy it is the sum of the two wedges that counts. Therefore it is plausible that incomplete depreciation allowances reinforce the effects of capital income taxation.Knowing the determinants of the two wedges one can easily derive the influence of a tax reform on the marginal productivity of capital, the market rate of interest and the rate of time preference (cf. Table 2). In the short run, the system of these three interest rates is anchored by the marginal productivity of capital, and hence any measure that widens a wedge is translated into a reduction in the rate or those rates below the wedge. In the long run the system is anchored by the rate of time preference and an increase in the width of a wedge is translated into an increase in those rates or that rate above this wedge.The paper was written in association with the Sonderforschungsbereich 5 (Staatliche Allokationspolitik im marktwirtschaftlichen System).     

CONSUMPTION AND LEISURE EXTERNALITIES, ECONOMIC GROWTH AND EQUILIBRIUM EFFICIENCY

This paper analyzes the effects of consumption and leisure externalities on growth and welfare in a two‐sector endogenous growth model with human capital accumulation. Both types of externalities are shown to affect the long‐run equilibrium and optimal growth rates in a rather different way. The relationship between the steady state of the market and the centrally planned economy is also analyzed. The optimal growth path can be decentralized by resorting to consumption or labor income taxation, whereas capital income should be untaxed. Numerical simulations suggest that growth and welfare effects of mild consumption and leisure externalities may be quantitatively important.     

The Division of Labor, Capital, Communication Technology and Economic Growth: The Case of China 1952–99

The implications of the division of labor, capital, and technology for economic growth have long been a fundamental issue in development economics. This paper employs the bounds testing approach to cointegration to examine the relationship between the division of labor, capital accumulation, communication technology, and economic growth for China over the period 1952–99. We find that in the long run, capital stock and the division of labor both have statistically significant positive effects on growth, while in the short run the effects are not significantly positive. Telecommunication technology, rather surprisingly, has a statistically insignificant impact on growth both in the long run and in the short run. Our findings indicate that there exists a long run equilibrium relationship between capital and the division of labor on the one hand, and economic growth on the other, thereby lending support to the division of labor theory of growth.

Fiscal Competition and Growth When Capital Is Imperfectly Mobile*

Is tax competition good for economic growth? We address this question using a simple model of endogenous growth. Governments in a system of many small jurisdictions benevolently maximize the welfare of immobile residents. Quadratic (de‐)installation costs limit the mobility of capital. We look at optimal taxation and long‐run growth, and we analyse the effects of cost parameter variations on taxation and growth. A race to the bottom in capital tax rates is only one possibility; the relationship between capital mobility and capital tax rates is not monotonic. Growth and capital mobility are unambiguously positively related.     

Ramsey fiscal policy and endogenous growth

This paper examines the effects of fiscal policies on capital accumulation and economic performance in a simple endogenous growth model with elastic labor supply by focusing on the implementability of a competitive equilibrium with productive public spending and distortionary taxation. Given a feasible exogenous fiscal policy, productive public spending can, at first, lead to positive short-run and long-run growth in the unique competitive equilibrium. However, although strictly positive growth is possible in the short run, a Ramsey policy with productive public spending does not implement positive capital accumulation in the long run. Also, the local indeterminacy of Ramsey allocations, in conjunction with the global multiplicity, arises as an implementable competitive equilibrium with Ramsey policies: namely, a continuum of transitional dynamics and multiple balanced growth paths.

Redistributive policy,inequality and growth

Does redistribution increase inequality? Is inequality harmful for growth? Both questions have recently been addressed in a number of single-tax models. In this paper, I examine the relationship between policy, growth and inequality when income and inherited wealth can be taxed at different rates. In the model, parents accumulate human capital and a return-bearing, storable good in order to increase the quality of their children. Inequality arises because the learning ability of children is stochastic. Redistributive labor income taxation has a negative impact on short- and long-run growth while taxation of inherited stocks increases growth. Effects of both taxes on income inequality are ambiguous. A switch from income to inheritance taxation may increase average utility of all generations involved. I calculate a structure-induced equilibrium of the political process by means of a stochastic simulation of the model. In the short run initial wealth-inequality can stimulate growth, while initial inequality of the endowment with human capital is harmful for growth.     

人工智能的财富分配效应研究*

人工智能对经济不平等的影响引起学术界的广泛重视，但是现有研究以分析其对劳动收入不平等的影响为主，关于人工智能对财富分配从而对财产性收入不平等影响的相关研究尚有欠缺。本文通过构建一个连续时间异质性个体动态一般均衡模型，将人工智能对生产技术的影响看作一揽子偏向性技术进步，研究人工智能技术对财富分配的影响。分析发现，人工智能对财富不平等的影响在短期和长期表现有所不同，短期中人工智能技术的应用会提高经济中财富分配不平等程度，而长期中其财富分配效应则取决于人工智能对不同类型技术进步的促进程度。核心机制在于，人工智能技术进步的多样性在短期和长期中对资本回报率产生不同影响，短期中各类技术进步总是会提高资本回报率，而在长期，不同类型的技术进步对资本回报率的影响出现差异。基于以上结论，本文就我国如何在应用人工智能促进增长的同时预防不平等程度扩大提出了政策建议。

Exchange rate volatility–economic growth nexus in Uganda

The global financial crisis has disrupted trade and capital flows in most developing economies, resulting in an increased volatility of exchange rates. We develop an autoregressive distributed lag model to investigate the effect of exchange rate volatility on economic growth in Uganda. Using data spanning the period 1960–2011, we find that exchange rate volatility positively affects economic growth in Uganda in both the short run and the long run. However, in the short run, political instability negatively moderates the exchange rate volatility–economic growth nexus. These results are robust to alternative specifications of the economic growth model.     

Welfare improving distributionally neutral tax reforms

In a new model with incomplete markets, I quantitatively determine tax reforms that are welfare improving, distributionally neutral, and leave the budget balance unchanged in the long run. I consider a new reform. I eliminate capital income taxation and replace it with progressive consumption taxation, consisting of taxing necessities and luxuries at different rates. I compare steady states under various tax regimes. I find that progressive rather than uniform consumption taxation generates higher welfare gains in the long run and during the transition to the steady state. While this type of reform achieves redistribution neutrality only in the long run, it generates welfare gains for the whole population during the transition.     

Equilibrium capital taxation in open economies under commitment

This paper analyzes equilibrium capital taxation in open economies with strategic interaction in a neo-classical growth model. Under perfect commitment, I show that non-cooperative capital taxes are zero in the long run for a large open economy, thereby generalizing the result previously established only for the special cases of a closed and a small open economy. This does not represent a race to the bottom, though, since the result is independent of the degree of capital mobility, the number of countries, or a country׳s size relative to the rest of the world. Moreover, when countries cooperate, they still set capital taxes to zero in the long run. These outcomes are robust to different equilibrium specifications, the inclusion of endogenous government spending, and heterogeneous agents and non-linear labor income taxation. Governments find it optimal to implement the efficient capital allocation in the long run, both in a closed and an open economy; this trumps incentives to tax foreigners’ domestic capital holdings by raising capital taxes and attracting capital from abroad by lowering capital taxes.     

China's Growing Government Debt in a Computable Overlapping Generations Model

This paper simulates the effects of China's growing government debt in a computable equilibrium model of overlapping generations. Our model assumes that the government increases debt to finance its spending in the short run, and then increases taxes or cuts spending to keep the debt–GDP ratio constant. The spending‐driven government debt increases public capital and output in the short run, but decreases private investment, total capital stock, output, and net exports in the long run, and makes the future generations worse off. Among various means of debt control, a decrease in government spending seems to be the least harmful to private investment, capital stock, and output while an increase in capital taxation is most detrimental.     

The influence of capital controls on long run growth: Where and how much?

The financial crisis in East Asia generated a revival of interest in the merits of financial openness. The ensuing debate on the benefits of openness has focused more on short and medium run issues than on the long run effects. Within the empirical literature on economic growth, little or no attention has been paid to the effects of financial openness. Contrary to the orthodox position, the few results that exist suggest that capital controls have no effect on economic growth. This paper argues that this conclusion emerges from a failure to account for underlying differences across countries with similar degrees of capital controls. We show that the degree of ethnic and linguistic heterogeneity in a country plays a significant role in explaining the effects of controls on economic growth. For countries with relatively higher degrees of ethnic heterogeneity, the effects are particularly adverse whereas for countries with high degrees of homogeneity, capital controls actually have a net positive effect on economic growth. On balance, more developing countries suffered due to controls than not. Within the sample of 57 non-OECD countries that did implement controls for the period 1975–1995, as many as 39 saw a reduction in their growth rates. This result is robust to a number of variables commonly used in the economic growth regressions.     

财政政策、货币政策与国外经济援助

本文通过把国外经济援助分成直接对私人的经济援助和直接对政府的经济援助来讨论这两类经济援助对政府财政政策和货币政策的影响。我们发现对私人的经济援助的增加可以使得私人消费水平和政府公共消费水平增加 ,但是它也导致政府收入税税率和通货膨胀率的提高 ;另一方面 ,对政府的经济援助增加可以使得均衡时的私人资本存量、私人消费水平和政府公共消费水平增加 ,同时可以使得均衡时的收入税税率和通货膨胀率下降。     

ICT效应下外商直接投资、经济增长与能源消耗 ---基于半参数空间向量自回归模型的研究

基于中国30个省份面板数据，通过构建半参数空间向量自回归模型（SSPVAR），利用时空脉冲响应函数、偏导图探讨了经济增长、能源消耗及外商直接投资的时空传导效应与信息与通讯技术（ICT）非线性的影响作用。研究结果显示：外商直接投资、经济增长及能耗强度受到彼此冲击后的响应较为明显；能耗强度具有自强化效应，空间溢出作用促进了周边省份经济发展，短期内不利于其外资引入，但长期却能提高外资利用。经济发展产生不可持续的自身累积效应，与单位产值能耗走在了“U”的上行区，但却对邻近区域产生了积极的正向溢出。外资长期利好效应凸显，发挥经济发展和能源节约的促进作用；短期内却抑制经济发展，强化能耗度，更无法发挥“示范”效应吸引更大规模的外资流入。ICT具有正向的节能、增产和引流效应，分别以倒V和V型形态推进，但是发展的初级阶段却没有任何影响作用。加速ICT应用，智能化和信息化商业、生产模式转型将有助于更少能耗的经济高质量发展。     

R&D, Imperfect Competition and Growth with Human Capital Accumulation

This paper studies the long‐run consequences of imperfect competition on growth and the sectoral distribution of skills within an R&D‐based growth model with human capital accumulation. We find that steady‐state growth is driven only by incentives to accumulate skills. In the model imperfect competition has a positive growth effect, while influencing the allocation of human capital to the different economic activities employing this factor input. Contrary to general wisdom, the share of resources invested in R&D turns out not to be monotonically increasing in the product market power and its correlation with the equilibrium output growth rate is not unambiguous.     

Capital specificity,imperfect labor mobility and growth in developing economies

Labor markets in developing economies may be afflicted by a multiplicity of interacting distortions. We consider a general equilibrium model of an economy distorted by both sector-specific sticky wages and imperfect mobility of labor. In this framework, we contrast the implications of capital accumulation in the short and long run. We show that, in contrast to both the case in the absence of a sector-specific sticky wage and the case in the absence of imperfect labor mobility, the short and long-run effects of growth on the economic system converge as the degree of labor mobility is limited.     

CIGARETTE TAXATION AND DEMAND: AN EMPIRICAL MODEL

This paper evaluates the impact of taxation on cigarette consumption, using a recursive model that includes a retail price equation and a dynamic demand equation. The analysis is based on panel data for 11 western states over the period 1967–1990. Results indicate that cigarette consumption is price-sensitive, with a demand elasticity of –0.40 in the short run and –0.48 in the long run. A tax increase, such as that imposed in California in January 1989, can have a strong effect of reducing cigarette consumption by between 11.2 percent in the short run and 13.4 percent in the long run. These results support the theory of rational addiction and the hypothesis that, as a part of their oligopoly behavior, the tobacco companies often do raise end-market prices by more than the amount of the increase in tax rates .     

Solving optimal growth models with vintage capital: The dynamic programming approach

This paper deals with an endogenous growth model with vintage capital and, more precisely, with the AK model proposed in [R. Boucekkine, O. Licandro, L.A. Puch, F. del Rio, Vintage capital and the dynamics of the AK model, J. Econ. Theory 120 (1) (2005) 39-72]. In endogenous growth models the introduction of vintage capital allows to explain some growth facts but strongly increases the mathematical difficulties. So far, in this approach, the model is studied by the Maximum Principle; here we develop the Dynamic Programming approach to the same problem by obtaining sharper results and we provide more insight about the economic implications of the model. We explicitly find the value function, the closed loop formula that relates capital and investment, the optimal consumption paths and the long run equilibrium. The short run fluctuations of capital and investment and the relations with the standard AK model are analyzed. Finally the applicability to other models is also discussed.
