Effects of Patent Protection on Optimal Corporate Income and Consumption Taxes in an R&D‐Based Growth Model

Does reducing the corporate income tax accompanied by an increase in the consumption tax to meet the government's budget constraint improve welfare? To respond, we examine the welfare‐maximizing corporate income tax and consumption tax rates in an R&D‐based growth model under the constraint that the government's budget is balanced at each point of time. Further, we consider how welfare‐maximizing tax rates change as patent protection becomes stronger, as seen in many countries. The results show that as patent protection becomes stronger, the corporate income tax rate should be higher and the consumption tax rate should be lower. This implies that under stronger patent protection, recovering production at the expense of innovation by raising corporate income tax and reducing consumption tax improves welfare.

The Long‐run and Short‐run Effects of Foreign Direct Investment on Financial Development in African Countries

This paper contributes to the understanding of the other neglected effects of foreign direct investment (FDI) by analysing how FDI affects financial development in the short run and long run for a panel of 49 African countries over the period 1990–2016. The empirical evidence is based on a pooled mean group approach. With three panels differentiated by income level, the following findings are established: first, while there is a positive and significant long‐run relationship between FDI and financial development in Africa, in the short run the effect of FDI on financial development is negative. Second, the effect of FDI is positive and significant in the long run in the three sub‐samples. However, in the short run, the effect of FDI is negative and significant in lower‐income countries and non‐significant in lower‐middle‐income and upper‐middle‐income countries. Overall we find strong evidence supporting the view that FDI promotes financial development in African countries in the long run.     

Trade Opening,Fiscal Reforms,Poverty, and Inequality: A CGE Analysis for Bangladesh

We assess the short‐ and long‐run impacts of tariff reform policies on Bangladeshi households' poverty and income distribution by developing an 86‐sector, four‐factor, and nine‐household‐group computable general equilibrium (CGE) model. The main findings are that the complete removal of tariffs leads to a decrease in overall poverty with rich household groups in a relatively better position. In the short run poverty incidence increases for rural landless, urban illiterate, and low‐educated household groups whereas rural large farmer and urban medium household groups enjoy improvements in all poverty indicators. In terms of income distribution, trade liberalization enhances inequality slightly, but there is a tendency towards more equitable distribution in the long run. The choice of a fiscal compensatory mechanism with consumption tax is likely to play a negative role in terms of poverty and inequality in the short run; however, interestingly, the results are pro‐poor in the long run.     

Dynamic Relationships between Exchange Rates and Foreign Direct Investment: Empirical Evidence from Korea

This paper examines the short‐run and long‐run dynamic relationships between exchange rates and foreign direct investment (FDI) in Korea. Monthly data retrieved from the Bank of Korea from January 1999 to March 2012 are examined. A cointegration test, a vector error correction model, the Wald test and impulse responses techniques are applied to analyze the data. The present study finds that, first, long‐run causation between exchange rates and FDI flows exists, which implies that a change in exchange rates negatively affects FDI flows in the long run. Second, short‐run causation between exchange rates and FDI flows exists, which confirms that there is reciprocal feedback between the two variables. Finally, the study finds evidence of a structural break from the global financial crisis of 2007–2009 shock to FDI flows in Korea. An external shock affects changes in the endogenous variables and, thus, causes instability in the cointegrating vector in the system.     

Factor shares,inequality, and capital flows

I present an endogenous growth model where innovations are factor saving and model the choice of technologies in an Overlapping Generations framework. Markets are competitive and factor prices are determined by marginal productivity of factors; therefore, the income share of reproducible factors increases with the stage of development. Beyond the standard results of this type of model I find that (i) without bequests long‐run growth is not possible, (ii) if the economy presents long‐run growth then intrageneration inequality may last forever but if the economy does not present long‐run growth then in steady state, there is no intrageneration inequality, (iii) when the economy is open, the pattern of capital flows depends not only on the relative abundance of factors but also on the technologies and, for this reason, capital may not flow from rich to poor economies, and (iv) consistently, capital flows may not help to break poverty traps.     

Is there any gain from social security privatization?

Increasing calls for a social security reform of switching from the pay-as-you-go (PAYG) system to a funded system has been seen in recent decades. This paper examines the effect of this reform on capital accumulation and the welfare of each generation. Three methods are used to finance the pension debt, government debt financing, tax financing, and government asset financing. With government debt or tax financing, the market equilibrium remains unchanged and all generations are as well off in the new system as in the PAYG system. Thus, switching from the PAYG system to a funded system is neutral. With government asset financing, the interest rate will decrease, private capital will increase, but the total output may either increase or decrease. The welfare effect is also ambiguous in general, depending on the rate of return of government assets. With plausible parameters, our simulation shows that the reform will lower the interest rate, increase private capital, and lower government capital in the short run, but raise government capital and increase output in the long run.     

How Can China Avoid the Middle Income Trap?

Many middle income economies have been unable to advance to become high income economies over a period of 50 years or longer, not due to the existence of middle income traps, but because of the overly broad income range in the definition of middle income economies. The middle income trap is, in essence, a growth trap, and refers to the situation in which a middle income economy experiences growth stagnation or a growth rate that is lower than that of high income economies. Nonetheless, it is hard to fully comprehend the formation of the trap solely based on growth theories. Historical data indicate that the middle income economies do not lack growth potential, and the real problem is that although their long‐term average growth rates are higher than those of the high income economies, their average growth rates over a business cycle or an even longer period of time often fall below those of the high income economies. The cause of this phenomenon is neither short‐term macroeconomic fluctuations nor long‐term growth potential, but the frequent occurrence of financial crises in middle income economies. As a middle income economy, China is also facing the risk of a financial crisis, and the key to avoiding the middle income trap is to guard against future financial crises, preventing unsound financial liberalization and mismanagement of the corporate debt ratio.     

LONG-RUN M3 DEMAND IN SOUTH AFRICA: A COINTEGRATED VAR MODEL

This paper presents a system cointegration analysis of a long‐run demand for money (measured in terms of M3) in South Africa. In particular, the paper estimates a cointegrated vector autoregression model, consisting of real money, income and the opportunity cost of holding money. Using a variety of theory consistent identification schemes, the money demand function is identified along with other two cointegrating relations, namely, an IS‐type relationship and a relationship relating inflation to the spread between long‐ and short‐term interest rates. The model shows that of the variables used, only income and real money are error‐correcting to the money demand relation. The money demand relation is found to be relatively stable over the sample period, when short‐run fluctuations are corrected for. The model further shows that the long‐run link between money and inflation is rather weak.     

The Elasticity of Taxable Income during the 1990s: New Estimates and Sensitivity Analyses

Over the past two decades, the elasticity of taxable income has emerged as the central parameter for assessing efficiency and revenue implications from changes to tax policy. This article estimates short‐ and longer‐run responses of taxable (and gross) income to changes in tax rates using panels of U.S. tax returns for the 1990s. With the richest set of income controls, income—weighted elasticity estimates range from 0.19 to 0.33, depending on whether responses are measured over one‐ or three‐year intervals. An alternative approach designed to capture delayed and anticipatory responses yields much larger estimates—ranging from 0.43 over the short term and from 0.78 to 1.46 over the longer term. A continuing obstacle to identification encountered here is that the income controls most likely to control for mean reversion and divergence within the income distribution are also the most likely to absorb independent variation in tax rates, also needed for identification.     

Strategic Tax and Financial Reporting Decisions: Theory and Evidence*

This paper examines the effect of book‐tax differences on the probability that a transaction is audited and the probability that additional taxes are collected. It constructs a stylized model in which the taxpayer reports both financial accounting income and taxable income. The government observes both reports before deciding whether to conduct an audit. The analysis of the equilibrium yields two hypotheses. First, the probability that the government will audit a transaction is higher if the transaction generates a positive book‐tax difference (e.g., an expenditure that is deducted for tax purposes but capitalized for financial reporting purposes) than if the transaction generates no book‐tax difference. Second, conditional on being selected for audit, transactions with and without book‐tax differences are equally likely to have detected understatements of tax liability. These hypotheses are tested using Internal Revenue Service (IRS) data from the Coordinated Examination Program. The empirical tests are consistent with the predictions of the strategic tax compliance model.     

Balanced‐budget rule,distortionary taxes and aggregate stability

It has been established under perfect competition and constant returns‐to‐scale that a one‐sector growth model may exhibit multiple stationary equilibria and local indeterminacy when income tax rates are endogenously determined by a balanced‐budget rule while government expenditures are fixed. The present paper shows that determinacy of the equilibrium trajectory is, however, generically preserved for a non‐empty range of initial values of the capital stock.     

Tax‐Avoidance Activities of U.S. Multinational Corporations*

This paper investigates whether economies of scale exist for tax planning. In particular, do larger, more profitable, multinational corporations avoid more taxes than other firms, resulting in lower effective tax rates? While the empirical results indicate that, ceteris paribus, larger corporations have higher effective tax rates, firms with greater pre‐tax income have lower effective tax rates. The negative relation between effective tax rates (ETRs) and pretax income is consistent with firms with greater pre‐tax income having more incentives and resources to engage in tax planning. Consistent with multinational corporations being able to avoid income taxes that domestic‐only companies cannot, I find that multinational corporations in general, and multinational corporations with more extensive foreign operations, have lower worldwide ETRs than other firms. Finally, in a sample of multinational corporations only, I find that higher levels of U.S. pre‐tax income are associated with lower U.S. and foreign ETRs, while higher levels of foreign pre‐tax income are associated with higher U.S. and foreign ETRs. Thus, large amounts of foreign income are associated with higher corporate tax burdens. Overall, I find substantial evidence of economies of scale to tax planning.

House Price Dynamics with Household Debt: The Korean Case*

This paper revisits the long‐run determinants of house prices, and analyzes the house price dynamics using Korean data taking into account the close relationship between house prices and household debt. The results of cointegrating regression indicate that the major portion of the rise in house prices in Korea over the last 15 years can be explained by changes in macro variables such as household income, the demographic structure, the user cost of home ownership and the housing stock supply. The results also confirm that house prices are, indeed, closely linked to the steep increase in household debt seen over this period. Estimation of an error correction model shows that the extent of convergence of actual house prices to their long‐run equilibrium path has weakened somewhat since the global financial crisis while the speed of convergence has slowed, indicating structural changes in the Korean housing market. Finally, a forecast for house prices over the next several years suggests that they are unlikely to rise as sharply as they did in the 2000s, given the likely changes in the macro‐financial environment, and that their future path will be closely associated with that of the household debt‐to‐income ratio.     

实质性减税降费与经济高质量发展

本文通过对我国减税降费政策发展演变过程的分析,阐释了实质性减税降费与经济高质量发展之间的关系。经济高质量发展就是以供给侧结构性改革为主线,推动经济发展质量变革、效率变革和动力变革。而我国减税降费政策的目标指向就是要实现经济高质量发展,通过降低增值税实现经济增长质量提升和经济结构改善,通过降低企业所得税实现企业效率变革,通过降低高层次人才个人所得税提高我国经济增长的知识含量和技术水平,从而实现动力变革。为此,一要在我国企业所得税支持国家创新体系"双重激励"的基础上,进一步完善高层次人才的税收支持体系,形成对国家创新体系的"三重激励";二要打造政府、企业、居民"多支柱养老模式",为企业轻装上阵奠定制度基础;三要适应经济金融化发展趋势,加强对数字经济的公平课税;四要落实好高质量征管,为实质性减税降费政策的实施保驾护航;五要处理好中央政府与地方政府间的财政关系。     

股利所得税差别化征收的市场效应研究——基于金融市场税收运行机制视角

财政部、国家税务总局、证监会于2012年11月16日颁布了《关于实施上市公司股息红利差别化个人所得税政策有关问题的通知》,此次税收调整的目的是通过有针对性的税收优惠政策进行结构性减税,确保资金的合理配置和股票市场的正常运行。通过事件研究法,从金融市场税收运行视角分析发现,此次股利所得税调整对过去一年发放股利的公司具有正向影响并且该影响具有时效性,同时由于持有过去一年股利发放公司股票的投资者大多属于长线投资者,此次税改对该类投资者而言是一种实质上的减税,因此本次税改在短期内产生了显著的微观经济效应,达到了政策设计的初衷,为大盘蓝筹股的价值提升了市场地位,为公司的直接融资提供了市场基础。     

Export taxes and income distribution: The Philippines coconut levy

Export Taxes and Income Distribution: The Philippines Coconut Levy. — A large, empirically based general equilibrium model of the Philippine economy is used to analyze the implications of a tax on coconut oil exports. The analysis shows how general equilibrium models can be used to derive optimal tax rates and to show the detailed relationship between the rates at which these taxes are applied and their economic effects. The analysis explores in particular the effects such taxes have on economic welfare and on income distribution within the country. The distributional effects of this export tax are shown to be highly regressive, revealing more clearly the policy trade-offs such taxes involve.     

Monetary Policy Impulses and Retail Interest Rate Pass‐Through in Asian Banking Markets

This paper considers the integration of financial markets and mutual influences of monetary policies in the USA and Asia based on monthly data from 1994 to 2007. We used panel‐type and time‐series and quantile panel‐type error correction models to test the influences of expected and unexpected monetary policy impulses on the interest rate pass‐through mechanism in the financial markets of 9 Asian countries and the USA. The empirics show that if interest rate integration exists in the financial markets, the following effects are observed: (i) positive impulses of unexpected monetary policy will lead to an increase in the long‐run multiplier of the retail interest rate; (ii) the adjustment of retail interest rates with short‐run disequilibrium will lead to an increase in the long‐run markup; and (iii) the empirical results of quantile regression prove that when the interest variation is greater than the 0.5th quantile and unexpected monetary policy impulses are greater than the expected monetary policy impulses, the short‐run interest rate pass‐through mechanism becomes more unstable.     

Taxation and Foreign Direct Investment Inflows: Time Series Evidence from the US

Abstract

This study investigates long run and short run relationships between the corporate income tax rate and foreign direct investment (FDI) inflows to the US. The tax rate is found to exert a significant negative effect on total FDI and transfer fund inflows in the long run. A 1% decrease in the tax rate would increase total FDI by 2.4% and transfer funds by 4.2%. Collectively, results suggest that the US can use tax policies to attract FDI from abroad. Concern over the possibility of tax competition among countries to attract foreign capital is warranted.
